This invention generally relates to a coating for optical surfaces, to improve energy conversion. More particularly, the invention relates to a coating for improving energy conversion in optoelectronic devices. The invention also relates to optoelectronic devices using such coatings.
One of the main focuses in the field of optoelectronic devices is the improvement of energy conversion efficiency (from electromagnetic energy to electric energy or vice versa). The devices often suffer reduced performance due to loss of light. Therefore, research in optical designs of these devices includes light collection and trapping, spectrally matched absorption and up/down light energy conversion.
A potential method of light collection is the reduction of light reflection by having a reflection-free surface. To this end, anti-reflection coatings of suitable refractive indices are commonly used. However, the availability of such materials having a low refractive index, e.g., between 1.0 (air) and 1.49 (glass), is very limited.
It is seen from current research that nanostructured optical thin films with controllable porosity often exhibit a very low refractive index as compared to dense materials. For example, SiO2 nanostructured porous films often have a refractive index of about 1.08, which is much lower than the value of 1.46 for an SiO2 thin film. These single layer anti-reflection coatings reduce reflectivity only in a limited spectral range, and for normal incidence.
Furthermore, the devices suffer loss of efficiency due to a thermalization mechanism in which carriers generated by high-energy photons are lost as phonons in the crystal. The absorption of incident photons with energies greater than the threshold energy for the absorption leads to the generation of only one electron-hole pair per absorbed photon, regardless of the photon energy. The excess energy of an incident photon above the threshold energy is wasted during the thermalization of the generated electron-hole pairs. Certain cell designs, employing a heterojunction window layer, lose high-energy photons due to parasitic absorption in the window layer. It is therefore desirable to convert these high-energy photons (short wavelength) to lower energy photons (long wavelength) that can be effectively absorbed in an absorber layer, and converted to collectable charge carriers.
One well-known method to overcome loss of light and related loss mechanisms involves “down-conversion” of high electromagnetic energy from a shorter wavelength to a longer wavelength. Because the absorption of high-energy photons in an undesired regions/layers of optoelectronic devices must be avoided, a down-converting layer may be disposed on a surface of the device, exposed to electromagnetic radiation.
Usually, deposition of anti-reflection and down-converting layers includes multiple processing steps. Thus, it would be desirable to produce improved coating systems having both anti-reflecting and down-converting properties, in order to meet various performance requirements for optoelectronic devices. Moreover, the new coating system can provide the advantage of easy fabrication. It would also be very desirable to develop an improved optoelectronic device including such coating.

Lesson: Optoelectronic Devices and Energy Conversion

Introduction:
Optoelectronic devices are devices that convert electromagnetic energy into electric energy or vice versa. These devices are widely used in various applications such as solar panels, LED lights, and photodetectors. The efficiency of these devices is crucial for their performance, and therefore, researchers are constantly working on improving their energy conversion capabilities. In this lesson, we will learn about the principles behind optoelectronic devices and the methods used to improve energy conversion efficiency.

Section 1: Optoelectronic Devices and Energy Conversion

Topic 1: Principle of Optoelectronic Devices
Optoelectronic devices work on the principle of converting electromagnetic energy into electric energy or vice versa. This is achieved through the use of semiconductor materials that absorb photons and generate electron-hole pairs. These electron-hole pairs are then separated by an electric field, creating a current flow.

Topic 2: Light Collection and Trapping
One of the main challenges in optoelectronic devices is to collect and trap as much light as possible. This can be achieved through the use of light-trapping structures such as nanostructures, microstructures, and metasurfaces. These structures can increase the path length of light within the device, thereby increasing the chances of photon absorption.

Topic 3: Spectrally Matched Absorption
Another challenge in optoelectronic devices is to ensure that the absorbed light has a wavelength that matches the bandgap of the semiconductor material. This is known as spectrally matched absorption. This can be achieved through the use of quantum dots, which are nanoscale semiconductor particles with size-dependent bandgaps.

Topic 4: Up/Down Light Energy Conversion
In some cases, it is necessary to convert light energy from one type to another. For example, in solar cells, light energy is converted from up-light (photons) to down-light (electricity), while in photovoltaic devices, light energy is converted from down-light (electricity) to up-light (photons). This can be achieved through the use of appropriate materials and structures.

Section 2: Reflection-Free Surfaces

Topic 1: Reflection-Free Surfaces
One of the challenges in optoelectronic devices is the reduction of light reflection. This can be achieved by having a reflection-free surface. A potential method of achieving this is by using anti-reflection coatings of suitable refractive indices. These coatings can reduce the reflection of light and improve the overall efficiency of the device.

Topic 2: Anti-Reflection Coatings
Anti-reflection coatings are made of materials with a low refractive index, typically between 1.0 (air) and 1.4. These coatings can be applied to the surface of the optoelectronic device to reduce reflection and improve light collection. The choice of material depends on the specific application and the desired wavelength range.

Section 3: Practical Examples

Topic 1: Solar Cells
Solar cells are a common example of optoelectronic devices that convert sunlight into electricity. In order to improve their efficiency, researchers use light-trapping structures, quantum dots, and anti-reflection coatings. These techniques can increase the amount of light absorbed by the solar cell, leading to higher energy conversion efficiency.

Topic 2: LED Lights
LED lights are another example of optoelectronic devices that convert electrical energy into light. To improve their efficiency, researchers use light-emitting structures, quantum dots, and anti-reflection coatings. These techniques can increase the amount of light emitted by the LED, leading to higher energy conversion efficiency.

Section 4: Glossary

Anti-reflection coatings: A thin layer of material applied to the surface of an optoelectronic device to reduce reflection and improve light collection.

Quantum dots: Nanoscale semiconductor particles with size-dependent bandgaps, used to absorb light with specific wavelengths.

Light-trapping structures: Structures that increase the path length of light within an optoelectronic device, increasing the chances of photon absorption.

Metasurfaces: Artificially structured surfaces that can manipulate light at the nanoscale level.

Conclusion:
In this lesson, we learned about the principles behind optoelectronic devices and the methods used to improve energy conversion efficiency. We also learned about the importance of reflection-free surfaces and the practical examples of solar cells and LED lights. By understanding these concepts, we can apply them to new problems and develop more efficient optoelectronic devices.

Lesson: Understanding Door Closers

Introduction:
A door closer is a device that automatically closes a door after it has been opened. It is commonly used in public buildings such as schools, hospitals, and offices to ensure that doors remain closed and secure. In this lesson, we will explore the different types of door closers, their technical diagrams, and their applications.

Section 1: Types of Door Closers

There are two main types of door closers: surface-mounted and concealed.

1. Surface-mounted door closers: These are mounted on the surface of the door and are visible from the outside. They come in different shapes and sizes, but the most common type is the pentagonal shape.

2. Concealed door closers: These are hidden inside the door and are not visible from the outside. They are usually more expensive than surface-mounted closers.

Section 2: Technical Diagram of a Door Closer

A door closer consists of several parts, including the arm, the spring, the strike plate, and the keeper. Here is a technical diagram of a typical door closer:

```mermaid
graph LR
    A(Arm) -->B[Spring]
    B --C[Strike Plate]
    C --D[Keeper]
    D --E[Door]
    E --F[Floor]
    B --G[Door Jam]
    G --H[Hinge]
```

The arm is attached to the spring, which provides the force needed to close the door. The strike plate is attached to the door frame, and the keeper is attached to the door. When the door is opened, the keeper moves away from the strike plate, allowing the door to open. When the door is closed, the spring pulls the arm back to its original position, and the keeper hits the strike plate, closing the door.

Section 3: Applications of Door Closers

Door closers are used in a variety of applications, including:

1. Schools: To ensure that classroom doors remain closed during class time and to prevent unauthorized entry.
2. Hospitals: To maintain a sterile environment and to prevent the spread of germs.
3. Offices: To keep the office secure and to prevent theft or vandalism.
4. Hotels: To maintain the privacy of guests and to prevent unauthorized access to rooms.
5. Public buildings: To ensure that doors remain closed and secure at all times.

Conclusion:
In this lesson, we have explored the different types of door closers, their technical diagrams, and their applications. By understanding the function and importance of door closers, we can ensure that our buildings remain secure and safe.

Efficiency of composite laboratory tests in the diagnosis of liver malignancies.
The utility of the markers CEA, beta-HCG, CA-50, alpha-fetoprotein (APF), ferritin, alkaline phosphatase (AP), its isoenzyme liver-1 (APL1), gamma-glutamyltransferase (gGT), its fast migrating isoenzyme (gGT1) and 5'nucleotidase (5'N) in differentiating liver malignancies and benign involvement was evaluated in the sera of 85 patients with hepatocellular carcinoma (HCC), 157 with chronic liver disease (CLD) and 91 with liver metastases (LM) derived from different tumors. The mean concentrations of all the parameters except CEA and GGT1 were significantly different in HCC and CLD, but a broad overlap existed in the two groups, so different cut-offs were considered to assess the positive and negative predictive values and test efficiency (Eff). The best results were observed considering AFP greater than 100 IU/m (Eff0.86), ferritin greater than 800 ng/ml (Eff0.69), CA-50 greater than 100 U/ml (Eff 0.63), beta-HCG greater than 10 mU/ml (Eff 0.61), AP greater than 300 IU/ml (Eff 0.66), the presence of APL1 (Eff 0.78), 5'N greater than 25 mU/ml (Eff 0.70), gGT greater than 100 mIU/ml (Eff 0.63). Among HCC patients 17% did not secrete AFP; in 26% the protein was less than 100 IU/ml and in 36% less than 400 IU/ml. Apart from AFP the most effective marker was APL1. At the above cut-offs more than three parameters were simultaneously positive in 71% of HCC and 9.9% of CLD. CEA, CA50, AFP were the only parameters that distinguished the HCC from the LM group; in the latter, APL1 was also a very sensitive marker (87%) for neoplastic involvement of the liver.

Lesson Title: Understanding Efficiency in Diagnosing Liver Malignancies

Introduction:
In this lesson, we will learn about the importance of efficiency in diagnosing liver malignancies. We will explore the different markers used to differentiate between liver malignancies and benign involvement, and analyze their effectiveness in detecting liver cancer.

Section 1: What is Efficiency?
Efficiency is a measure of how well a process converts input into output. In the context of medical testing, efficiency refers to the ability of a test to accurately identify those who have a specific condition (in this case, liver malignancies) while minimizing the number of false positives and negatives.

Section 2: Markers for Liver Malignancies
Several markers have been developed to help diagnose liver malignancies. These markers are proteins or enzymes that are present in higher levels in individuals with liver cancer. Some of the most commonly used markers include:

- Alpha-fetoprotein (AFP): This protein is produced by the liver during fetal development but can be elevated in adults with liver cancer.
- Beta-human chorionic gonadotropin (beta-hCG): This hormone is usually only found in pregnant women, but it can also be elevated in some individuals with liver cancer.
- Carcinoembryonic antigen (CEA): This protein is present in higher levels in individuals with certain types of cancer, including liver cancer.
- Cancer antigen 50 (CA-50): This protein is present in higher levels in individuals with certain types of cancer, including liver cancer.
- Ferritin: This protein is involved in iron storage and can be elevated in individuals with certain types of cancer, including liver cancer.
- Alkaline phosphatase (ALP): This enzyme is present in higher levels in individuals with certain types of cancer, including liver cancer.

Section 3: Evaluating Efficiency
To determine the efficiency of these markers in diagnosing liver malignancies, researchers conducted a study involving 85 patients with hepatocellular carcinoma (HCC), 157 with chronic liver disease (CLD), and 91 with liver metastases (LM) derived from different tumors. They analyzed the mean concentrations of each marker in each group and determined the optimal cut-off values for each marker to maximize the positive predictive value (PPV) and negative predictive value (NPV).

Section 4: Conclusion
Understanding the efficiency of diagnostic tests for liver malignancies is crucial for ensuring accurate diagnoses and effective treatment. By evaluating the performance of different markers, researchers can determine which tests are most effective in identifying liver cancer and improve patient outcomes.

Glossary:
- Efficiency: The ability of a process to convert input into output while minimizing waste and maximizing productivity.
- Markers: Proteins or enzymes that can be measured in the blood to indicate the presence of a specific condition or disease.
- Liver malignancies: Cancers that originate in the liver.
- Benign involvement: A condition or disease that is not cancerous or malignant.
- Positive predictive value (PPV): The probability that a test result will be positive given that the person has the condition.
- Negative predictive value (NPV): The probability that a test result will be negative given that the person does not have the condition.

Self-Debating Discussion:
1. How does the efficiency of a diagnostic test affect patient outcomes?
2. Which marker(s) do you think are the most effective in diagnosing liver malignancies? Why?
3. How might the results of this study impact the way liver cancer is diagnosed in the future?

Top 5 Worst Computer Viruses – You should know

Getting infected with a malicious file is something that has happened to all computer operators at least once, in one fashion or the other. For most people, the situation is quite mild, requiring only a simple clean up, by installing and running a full virus scan of their system. But in other cases, the situation can be disastrous, with the computer completely bricking your system, which no antivirus software can protect your system from.

In this article, I will highlight some of the worst computer viruses in history, viruses that have caused a considerable amount of damaged to peoples and property.

This article will include all malicious files that include Trojan horses and worms. To date, these malicious files have been responsible for a considerable amount of damage, numbering in the billions.

Here are the five worse computer viruses:

1. ILOVEYOU

The ILOVEYOU virus was known for being one of the widest spread in history, this virus was successful in wreaking havoc on millions of computer systems all over the world, causing an estimated $10 billion in damages. Estimates put the infected at 10% of the whole internet population at the time. This virus was so bad, that large corporations were forced to put their mailing systems offline, just to prevent it from infecting them.

Two Filipino programmers, Onel de Guzman and Reonel Ramones were found responsible for its creation. It worked by applying social engineering in order to get people to click on the attachment, in this case, it was a confession of love. The attachment, however, was a script disguised as a text document. Windows inability to show file extensions on attachments at the time was what they used to deceive the masses.

Once you clicked on it, it would send itself to everyone on your mailing list, while overwriting your computer files, replacing them with its self, thus making your system unbootable. The two programmers were never sentenced in a court of law, primarily because malware laws didn’t exist back then. However, this one single event led to the eCommerce law.

2. The Concept Virus

The Concept virus, as it was known, was shipped accidentally on a CD-ROM which was supplied by Microsoft way back in 1995. This was the first virus to actually infect Microsoft Word. Within just a couple of days, a significant amount of the computer user population was infected with this virus. The virus itself took advantage of people’s tendency to share documents across the internet.

3. The Anna Kournikova Worm

The Anna Kournikova worm was created and disguised as a picture of the tennis player. The worm was created by Jan de Wit, who was an obsessed admirer of her. He was eventually arrested and given a community service sentence.

4. Code Red

Code Red first arrived in 2001 and was discovered by two security employees at eEye Digital. The virus was named Code Red, because the two security guards were drinking Code Red Mountain Dew when they first discovered it. The worm worked by exploiting vulnerabilities in the buffer overflow problem of computer systems that had Microsoft IIS web server installed. The worm ran entirely on memory, which means little to no trace of it was left on the system. Its file size was around 3 bytes, to its advantage and once it got onto your system, it would proceed to replicate itself while at the same time consuming more and more system resources.

It would then launch a DoS or Denial of Service attack on several IP addresses which were widely used by the White House. It would also allow the hacker to gain backdoor access to a server. One of the most memorable things about it was the message it left on web pages that it had hacked “Hacked by Chinese!” This message went on to become a meme itself. A patch was eventually released which counter the worm, but by that time, it had already caused $2 billion in damages, due primarily to losses in productivity. The worm affected an estimated 1 – 2 million servers, which was a considerable amount, especially when you consider the fact that there were only 6 million IIS servers at that time.

5. Netsky and Sasser

The Netsky and Sasser worms were written by German teenager Seven Jaschan who was eventually caught and arrested. At the time of his arrest, he was found to be responsible for more than 70% of all the malware circulating the internet at the time, but was fortunate to escape prison time, later going on to be hired by a security company as an ethical hacker.

Cutaneous pseudosarcomatous polyp: a recently described lesion.
Three cases of cutaneous pseudosarcomatous polyp, a lesion recently described in the dermatopathology literature, are reported here. These benign proliferations display dramatic cytologic pleomorphism, but despite their disquieting morphological features, they have behaved in a benign fashion to date. All 3 lesions in this study were clinically innocuous, with 1 having been present for 1 year and another for 2 years. The first lesion arose on the back of a 30-year-old man, the second on the nasal columella of a 65-year-old woman, and the third on the back of a 91-year-old woman. All 3 had the typical architecture of a fibroepithelial polyp (acrochordon) with widely separated stellate cells occupying a myxoid to collagenous stroma. Markedly pleomorphic stellate cells were widely dispersed, with an increased density of atypical cells beneath the epidermis and in small foci of adipose tissue in 1 case. Multinucleated cells, some with a floret-type configuration, were also observed. One of the polyps demonstrated focal mild hyalinization of vessel walls. Only rare mitotic figures were identified in 2 cases, but 1 showed atypical forms. Immunohistochemically, the atypical cells reacted diffusely for vimentin and variably for CD34 and factor XIIIa, but they lacked smooth muscle actin and desmin. Cutaneous pseudosarcomatous polyps can be added to the list of pathologic entities with symplastic or pseudomalignant features.

Lesson: Introduction to Cutaneous Pseudosarcomatous Polyp

### Overview
In this lesson, we will learn about cutaneous pseudosarcomatous polyp, a recently described lesion in the dermatopathology literature. We will explore its characteristics, diagnosis, and treatment options.

### Objectives
- Understand the definition and characteristics of cutaneous pseudosarcomatous polyp
- Recognize the diagnostic criteria for cutaneous pseudosarcomatous polyp
- Identify the treatment options for cutaneous pseudosarcomatous polyp

### Section 1: Introduction to Cutaneous Pseudosarcomatous Polyp

Cutaneous pseudosarcomatous polyp is a recently described lesion in the dermatopathology literature. It is a benign proliferation that displays dramatic cytologic pleomorphism. Despite its disquieting morphological features, it has behaved in a benign fashion to date.

### Section 2: Characteristics of Cutaneous Pseudosarcomatous Polyp

Cutaneous pseudosarcomatous polyp typically presents as a fibroepithelial polyp (acrochordon) with widely separated stellate cells occupying a myxoid to collagenous stroma. Markedly pleomorphic stellate cells are widely dispersed, with an increased density of atypical cells beneath the epidermis and in small foci of adipose tissue in some cases.

### Section 3: Diagnosis of Cutaneous Pseudosarcomatous Polyp

The diagnosis of cutaneous pseudosarcomatous polyp is based on histopathological examination. A biopsy of the lesion is taken and examined under a microscope. The presence of widely separated stellate cells, an increased density of atypical cells, and marked pleomorphism are indicative of cutaneous pseudosarcomatous polyp.

### Section 4: Treatment Options for Cutaneous Pseudosarcomatous Polyp

Treatment options for cutaneous pseudosarcomatous polyp include surgical excision, cryotherapy, and topical chemotherapy. The choice of treatment depends on the size, location, and aggressiveness of the lesion. In most cases, surgical excision is recommended as it provides a definitive diagnosis and allows for complete removal of the lesion.

### Glossary
- Cutaneous: related to the skin
- Pseudosarcomatous: resembling sarcoma (a type of cancer) but not actually being sarcoma
- Polyp: a small projection or outgrowth from the surface of an organ, especially one containing fluid-filled cavities or sacs
- Dermatopathology: the study of diseases of the skin
- Stellate cells: star-shaped cells
- Myxoid: resembling or containing myxoma (a type of connective tissue)
- Collagenous: containing or resembling collagen (a type of protein found in connective tissues)

### Conclusion

We present advances in the use of single-molecule FRET measurements with flexibly linked dyes to derive full 3D structures of DNA constructs based on absolute distances. The resolution obtained by this single-molecule approach harbours the potential to study in detail also protein- or damage-induced DNA bending. If one is to generate a geometric structural model, distances between fixed positions are needed. These are usually not experimentally accessible because of unknown fluorophore-linker mobility effects that lead to a distribution of FRET efficiencies and distances. To solve this problem, we performed studies on DNA double-helices by systematically varying donor acceptor distances from 2 to 10 nm.Overview. Molecular physical chemistry:. Anna K.

Lesson: Introduction to Single-Molecule Fluorescence Resonance Energy Transfer (FRET)

## Section 1: Theory

Fluorescence Resonance Energy Transfer (FRET) is a technique used to study the interactions between biomolecules at the molecular level. It involves the transfer of energy from a donor molecule to an acceptor molecule without the emission of a photon. This process is highly dependent on the distance between the donor and acceptor molecules, making it a powerful tool for studying molecular structures and interactions.

## Section 2: Practical Examples

One application of FRET is in the study of DNA structure. By labeling specific nucleotides with donor and acceptor fluorophores, researchers can measure the distance between these labeled nucleotides and determine the 3D structure of the DNA molecule. This information can be used to study the effects of protein binding or DNA damage on the structure of the DNA molecule.

Another application of FRET is in the study of protein-protein interactions. By labeling each protein with a donor and acceptor fluorophore, researchers can measure the distance between the two proteins and determine if they are interacting. This information can be used to study the function of the protein complex and identify potential drug targets.

## Section 3: Real-World Scenarios

A real-world scenario where FRET can be applied is in the study of cellular processes. By labeling specific proteins or nucleic acids with donor and acceptor fluorophores, researchers can track the movement and interactions of these molecules within living cells. This information can be used to study the dynamics of cellular processes and identify potential targets for therapeutic intervention.

## Glossary

- Donor: A molecule that transfers energy to an acceptor molecule in FRET.
- Acceptor: A molecule that receives energy from a donor molecule in FRET.
- Fluorophore: A molecule that emits light when excited by a specific wavelength.
- FRET efficiency: The ratio of the energy transferred to the acceptor molecule to the total energy emitted by the donor molecule.
- Distance: The distance between the donor and acceptor molecules is a crucial parameter in FRET experiments.

## Conclusion

Fluorescence Resonance Energy Transfer (FRET) is a powerful technique for studying molecular structures and interactions. By labeling molecules with donor and acceptor fluorophores and measuring the distance between them, researchers can gain valuable insights into the structure and function of biomolecules. This information can be used to study the effects of protein binding or DNA damage on molecular structure, as well as track the movement and interactions of molecules within living cells.
