[1] [2] [3] For example, with the use of electrospinning, the flexible nature of PDS allows the control of its structure and can be used in applications such as tissue scaffolding. [ 4 ] It is degraded by hydrolysis, and the end products are mainly excreted in urine, the remainder being eliminated by the digestive system or exhaled as CO 2 .
Worker placing a tire in a mold before vulcanization. Sulfur vulcanization is a chemical process for converting natural rubber or related polymers into materials of varying hardness, elasticity, and mechanical durability by heating them with sulfur [1] or sulfur-containing compounds. [2]
Curing is a chemical process employed in polymer chemistry and process engineering that produces the toughening or hardening of a polymer material by cross-linking of polymer chains. [1] Even if it is strongly associated with the production of thermosetting polymers , the term "curing" can be used for all the processes where a solid product is ...
[2] [3] [4] It is a very common material, [5] and is the oldest known ceramic. Prehistoric humans discovered the useful properties of clay and used it for making pottery. [6] The chemistry of clay, including its capacity to retain nutrient cations such as potassium and ammonium, is important to soil fertility. [7]
POM has a density of 1.410–1.420 g/cm 3. [5] Typical applications for injection-molded POM include high-performance engineering components such as small gear wheels, eyeglass frames, ball bearings, ski bindings, fasteners, gun parts, knife handles, and lock systems. The material is widely used in the automotive and consumer electronics industry.
A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.
Agents on patrol discovered two backpacks stuffed with more than $1.1 million worth of cocaine in Washington state near the border with Canada, U.S. Customs and Border Protection said Monday.
A honeycomb-shaped structure provides a material with minimal density and relative high out-of-plane compression properties and out-of-plane shear properties. [1] Man-made honeycomb structural materials are commonly made by layering a honeycomb material between two thin layers that provide strength in tension. This forms a plate-like assembly.
