Activated carbon: (also known as activated carbon) A type of carbon that comes as a powder or small granules. It is used to filter out anything that may be harmful, smelly, or have an unpleasant taste. Impurities are adsorbed (attached) to carbon. The small size of the particles increases the surface area of ​​the carbon. The same goes for grainy surfaces, which have many pores, like a sponge, and provide even more places for impurities to stick.
Algorithm: A set of rules or procedures for solving a problem in a series of steps. Algorithms are used in mathematics and computer programs to find solutions.
Analytical: (in chemistry) the field that focuses on how to separate materials into their parts or elements.
Cell: (in biology) the smallest structural and functional unit of an organism. They are usually too small to be seen with the naked eye and consist of a watery fluid surrounded by a membrane or wall. Depending on their size, animals are made up of thousands to trillions of cells.
Chemical bond: An attractive force between atoms that is strong enough to cause the combined elements to function as a single unit. Some gravitational forces are weak, while others are very strong. All bonds appear to hold atoms together through the sharing or attempted sharing of electrons.
Explanation: (in science) An opinion piece written to add perspective, often to accompany another’s paper explaining new research results.
Crops: (in agriculture) a type of plant that is intentionally cultivated and cultivated by farmers, such as corn, coffee, and tomatoes. Alternatively, the term may be applied to the part of a plant that is harvested and sold by a farmer. (zoology) A throat-like structure that allows animals, especially birds, to store food as they return to their nests from the field.
Electronics: A device that is powered by electricity but whose properties are controlled by a semiconductor or other circuit that controls or gates the movement of charge.
Environmental science: The study of ecosystems to help identify environmental problems and possible solutions. Environmental science integrates many disciplines such as physics, chemistry, biology, and oceanography to understand how ecosystems work and how humans can coexist harmoniously with them. can do. People who work in this field are known as environmental scientists.
False positive: In statistics, a conclusion based on data that a difference exists between two or more conditions being tested, even though none actually exists.
Field: Research fields such as: Her field of research is biology.
Filter: (n.) Something that, based on size or other characteristic, can pass through some substances but not others. (v.) The process of sorting some things out on the basis of their properties, such as size, density, or charge. (in physics) a screen, plate, or layer of material that absorbs light or other radiation, or selectively prevents the transmission of some of its components.
Fossil fuel: Fuels such as coal, petroleum (crude oil), and natural gas that have been produced within the Earth over millions of years from the decaying remains of bacteria, plants, and animals.
Laser: A device that produces an intense beam of coherent light of a single color. Lasers are used for drilling and cutting, alignment and guidance, data storage, and surgery.
Machine learning: A method in computer science that allows computers to learn from examples and experience. Machine learning is the basis of several forms of artificial intelligence (AI). For example, a machine learning system might compare her X-rays of a cancer patient’s lung tissue and compare whether and how long the patient survived after receiving a certain treatment. In the future, its AI systems may be able to examine new patients’ lung scans to predict how well they will respond to treatment.
Methyl methacrylate: Also known as MMA, this volatile synthetic chemical is used in the production of certain plastics and acrylic resins. Polymeric versions of MMA are also used to make adhesives, leather and paper coatings, inks, floor polishes, synthetic nails, and some textile finishes.
Micro: Prefix for fractional units of measurement. Here, we are referring to 1/1,000,000 in the international metric system.
Micro plastic: A small piece of plastic less than 5 millimeters (0.2 inches) in size. Microplastics may have been produced due to their small size. Alternatively, its size may be the result of the decomposition of a water bottle, plastic bag, or other object that was large to begin with.
Nano: Prefix indicating one billionth. In the metric system of measurement, it is often used as an abbreviation to refer to objects that are one billionth of a meter (nanometer) in length or diameter.
Nanoparticles: Small particles with dimensions in billionths of a meter.
Online: (noun) on the internet. (adjective) A term used to describe something that can be found or accessed on the Internet.
Particle: A trace amount of something.
PET: Abbreviation for polyethylene terephthalate. It is a commonly used plastic that can be produced as a strong, stable fiber for use in fabric manufacturing. It is also the basis of many plastic beverage bottles (such as milk jugs) and semi-hard food packaging (often used for produce). When used in fabrics, it is simply known as polyester. To identify these plastics in non-clothing products, a label with the number 1 surrounded by a triangular “tracking arrow” symbol and the acronym PET or PETE below the triangle should be placed on the bottom or They tend to be attached to the sides.
Physically: (adjective) A term used to describe something that exists in the real world rather than in memory or imagination. It can also refer to properties of a material due to size or non-chemical interactions (such as when one block collides with another block with force). (In biology and medicine) This term can refer to the body, such as a physical exam or physical activity.
Plastic: Any of a series of materials that are susceptible to deformation. or synthetic materials made from polymers (long strings of component molecules) that are lightweight, cheap, and resistant to deterioration. (adjective) A material that can be adapted by changing its shape or, in some cases, its function.
Polystyrene: Plastic made from chemicals refined from (manufactured from) crude oil or natural gas. Polystyrene is one of the most widely used plastics and is the ingredient used to make the widely used white rigid foam (often sold under the name Styrofoam).
PVC: (or PVC) This is a plastic formed by turning a liquid resin into a solid using heat. Plastics can be soft and flexible, or hard and rigid. The raw materials mainly consist of chlorine and carbon.
Proceedings of the National Academy of Sciences: A prestigious journal founded in 1914 that publishes original scientific research. The journal’s content spans biology, physics, and social sciences. Today, each of his more than 3,000 papers published each year is not only peer-reviewed, but also approved by members of the National Academy of Sciences.
Range: the total extent or distribution of something. For example, a plant or animal’s habitat is the area in which it naturally occurs.
Danger: The probability or mathematical probability that something bad will happen. For example, exposure to radiation poses a risk of cancer. Or danger, or danger itself. (for example: The cancer risks people faced included drinking water contaminated with radiation and arsenic.. )
Ocean: Ocean (or area that is part of the ocean). Unlike lakes and streams, sea water, or ocean water, is salty.
Skeptical: I’m not easily convinced. Having doubts or reservations.
System: A network of parts that work together to accomplish some function. For example, blood, blood vessels, and the heart are the main components of the human body’s circulatory system. Similarly, trains, platforms, tracks, road signals, and elevated tracks are among the potential components of a country’s railway system. Systems can also apply to processes and ideas that are part of a method or ordered sequence of steps for completing a task.
Technology: The application of scientific knowledge for practical purposes, especially in industry, or the devices, processes, and systems resulting from such efforts.
Toxicity: A measure of the likelihood that a substance will poison or harm living organisms.
Toxicologist: A scientist who investigates the potential harm caused by physical factors in the environment. These may include substances that you may be exposed to intentionally, such as chemicals, tobacco smoke, and food, or substances that you may be exposed to out of choice, such as air or water pollutants. . Toxicologists may study the risks such exposures pose, how they cause harm, and how they move throughout the environment.
Vibrate: To rock rhythmically or to move rapidly back and forth continuously.
