neuroscientist: Somebody who research the construction or perform of the mind and different components of the nervous system.
particle: A minute quantity of one thing.
plastic: Any of a sequence of supplies which are simply deformable; or artificial supplies which were comprised of polymers (lengthy strings of some building-block molecule) that are usually light-weight, cheap and proof against degradation. (adj.) A fabric that is ready to adapt by altering form or presumably even altering its perform.
Plexiglas: or plexiglass The primary is the trademarked title (the second is a extra basic title) for the chemical poly(methyl methacrylate). It’s a clear plastic that may resist shattering. It may be used rather than glass for a lot of functions.
polyester: An artificial materials used mainly to make materials. The precise chemical title for the fabric used is polyethylene terephthalate.
polyethylene: A plastic comprised of chemical compounds which were refined (produced from) crude oil and/or pure fuel. The most typical plastic on the earth, it’s versatile and difficult. It can also resist radiation.
polyethylene terephthalate: A generally used kind of plastic, normally referred to easily as PET. It may be produced as sturdy, secure fibers to be used in making clothes. It is also the idea of many plastic beverage bottles (resembling milk jugs) and semi-hard meals packages (usually used for produce). When utilized in materials, it’s merely often known as polyester. To determine these plastics in items apart from clothes, they have an inclination to hold a labeled on the underside or aspect with the number one surrounded by the triangular “chasing arrows” image and the acronym PET or PETE under the triangle.
polymer: A substance comprised of lengthy chains of repeating teams of atoms. Manufactured polymers embrace nylon, polyvinyl chloride (higher often known as PVC) and lots of kinds of plastics. Pure polymers embrace rubber, silk and cellulose (present in crops and used to make paper, for instance).
polypropylene: The second commonest plastic on the earth. It’s robust and sturdy. Polypropylene is utilized in packaging, clothes and furnishings (resembling plastic chairs).
polystyrene: A plastic comprised of chemical compounds which were refined (produced from) crude oil and/or pure fuel. Polystyrene is among the most generally used plastics, and an ingredient used to make a broadly used white, inflexible foam (usually offered underneath the title Styrofoam).
taint: To infect one thing with an surprising, unnatural or unlawful substance.
