A rheometer is a device that was developed to measure how a liquid’s suspensions or slurries flow when force is applied to it. Many fluids can be tested with a rheometer when a single numerical viscosity value cannot determine them due to their components. A rheometer can also be used to discover the additional parameters …
A nanotube is a cylinder made up of atomic particles and whose diameter is around one to a few billionths of a meter (or nanometers). They can be made from a variety of materials. Nanotubes are believed to be stronger than steel, but more flexible than plastic, and they also exhibit excellent thermal and electrical conductivity. These …
Biological computers are special types of microcomputers that are specifically designed to be used for medical applications. The biological computer is an implantable device that is mainly used for tasks like monitoring the body's activities or inducing therapeutic effects, all at the molecular or cellular level. The biological computer is made up of RNA (Ribonucleic …
Also known as body armors, there are different types of bullet proof vests. The most common is the soft vest usually used by the police force and private security; it cannot stop ammunition of big caliber. Hard-plate reinforced vests are necessary when heavy ammunition is involved; they are used as part of the default equipment …
An acrylic adhesive is a resin-based adhesive that is comprised of acrylic or methylacrylic polymers. It is rather complicated to produce acrylic adhesives as they must be formed into a polymer, suspended in a catalyst, and cured. Acrylic adhesives are very strong and efficient at bonding multiple objects together. They are resistant to sunlight, not …
Blackbody radiation refers to the electromagnetic radiation that a blackbody material expels. Blackbody materials are substances that absorb all electromagnetic radiation that comes in contact with it, including light and heat. While a perfect blackbody material does not exist in nature, substances such as ash, soot, and granite come close. When a blackbody material is …
Potassium benzoate is the potassium salt of benzoic acid. Benzoic acids are weak acids that are used as food preservatives. Potassium benzoate is also commonly used for preserving food. It is primarily used to inhibit mold and bacteria growth. This allows the product that potassium benzoate preserves to last longer on the shelf, thereby increasing …
An Ultrasonic Pest Repeller is an electronic device that uses ultrasonic sound waves to repel insects, rodents, and other pests. Though humans are incapable of hearing these sounds, many animals, insects, and rodents can. There is much debate concerning the ultrasonic pest repeller’s ability to actually get rid of pests. While some people claim that …
The Boltzmann Constant (Boltzmann’s Constant) is a fundamental physics constant that plays a pivotal role in almost every single statistical formulation in both quantum and classical physics. It is named after Austrian physicist, Ludwig Boltzmann (1844 – 1906), who made significant contributions to the foundation and development of a particular branch of theoretical physics known …
Photoelectron spectroscopy is the study of energy and how it relates to matter in terms of absorption and production. Photoelectron spectroscopy observes both wavelengths and frequencies and is used to view the physical composition of chemicals and solids. It is used in both analytical and physical chemistry and astronomy in order to study an object’s …
