Microplastics, small pieces of plastic, less than 5 mm (0.2 inch) in length, that occur in the environment as a consequence of plastic pollution. Microplastics are present in a variety of products, including cosmetics, plastic bags, and bottles. Many of
Gelatin is a soluble protein compound obtained by partial hydrolysis of collagen, the main fibrous protein constituent in bones, cartilages and skins; therefore, the source, age of the animal, and type of collagen, are all intrinsic factors influencing the properties of the gelatins (Johnston-Bank...
Tannins prevent this decomposition, and the process of applying tannin is called “tanning.” Sure Fit Soft Suede Chair Slipcover Finishing the Leather At this point, the leather that will be used to make suede is in a more-or-less finished state. To make a fabric recognizable as suede,...
Laser transmission welding of plastics is a joining technique which permits the welding of plastic parts with low process inherent thermal and mechanical stresses. In order to compute the temperature fields during the welding process a simulation model of the process is established. Especially the ...
Depending on the ability to divide, stem cells are classified into four categories: totipotent SCs that may differentiate into any kind of cells, including cells of the placenta; pluripotent SCs that may be a source of any kind of cell, except...
Carbon is considered to exist in three basic forms: diamond, graphite/graphene/fullerenes, and carbyne, which differ in a type of atomic orbitals hybridization. Since several decades the existence of the fourth basic carbon allotropic form with the face-
