Polymers

Polymers

The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the...

Protection of Alcohols

Protection of Alcohols

This lesson delves into the concept of protection and deprotection of a functional group fundamental to synthetic organic chemistry. These phenomena are explained in the context of aliphatic and aromatic alcohols.
Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...

Zones of Protection

Zones of Protection

In power systems, the entire setup is divided into protective zones to isolate faults and protect the rest of the network. These zones include generators, transformers, buses, transmission lines, distribution lines, and motors. Each zone can be visualized as a separate room in a house, with each room protected by its own circuit breaker.
Protective zones are defined by closed dashed lines, containing one or more components. A key characteristic of these zones is the strategic placement of...

Radial System Protection

Radial System Protection

Radial systems employ time-delay overcurrent relays to reduce load interruptions. When a fault occurs, the nearest breaker opens first, while upstream breakers remain closed due to longer delay settings. This approach ensures minimal disruption to the rest of the system.
In a radial system with a fault downstream of the third breaker, ideally, only the third breaker will open, isolating the fault and interrupting the load connected beyond it. The second breaker has a longer delay setting,...

Protecting Self-Esteem

Protecting Self-Esteem

Self-esteem, a central component of psychological well-being, is actively maintained through various cognitive and behavioral strategies. Individuals employ specific mechanisms to preserve a positive self-concept and mitigate threats to their self-worth, particularly in contexts involving social evaluation or personal feedback. Four primary techniques are commonly used to sustain self-esteem.Manipulating AppraisalsOne prominent strategy involves manipulating appraisals from others. Individuals...

Background:

Characterizing transparent protective coatings on functional materials is challenging.
Accurate thickness measurement is vital for optimizing coating performance.

Purpose of the Study:

To present a novel toolbox for determining transparent coating thicknesses on window films.
To validate the toolbox against established characterization techniques.
To assess the suitability of the coating for industrial applications.

Main Methods:

Development of a toolbox combining secondary ion mass spectrometry (SIMS) and profilometry.
Characterization of model samples using transmission electron microscopy (TEM) and scanning/transmission electron microscopy (STEM).
Ellipsometry for comparative thickness measurements.

Main Results:

The developed toolbox accurately measures coating thicknesses, comparable to electron microscopy.
The sol-gel alkoxide coating exhibits fast drying and complete condensation.
Low-temperature deposition (<100°C) and roll-to-roll compatibility enable industrial scalability.

Conclusions:

The presented toolbox offers a reliable method for transparent coating thickness characterization.
The developed coating and deposition process are suitable for industrial-scale production of infrared reflective window films.
The findings facilitate precise control over protective coating thickness for enhanced material properties.
