The mechanical properties of polymers, such as tensile strength, toughness, elasticity, and so on, are determined by intermolecular forces in the macromolecules, such as Van der Waal forces and hydrogen bonds.

The purpose of this chapter is to introduce the subject of microelectronic manufacturing defects and to show how they tie in to microelectronics processes. A further purpose of the chapter is to organize defects for ease in understanding, that is, by def
GLOBAL INDUSTRY CLASSIFICATION STANDARD (GICS®) METHODOLOGY FEBRUARY 2025 When no Sub-Industry provides the majority of both the company's revenues and earnings, the classification will be determined based on further research and analysis. In addition, a company significantly diversified across three ...
(NPs) were immobilized on the three silica-alumina materials (2.5 wt% metal loading) via a solution-based synthetic procedure (see further details in Methods) to give the main library of 12 catalysts, i.e., SiO2-Al2O3,Co/SiO2-Al2O3,Ni/SiO2-Al2O3,Ru/SiO2-Al2O3,Zeo-Y_H, Co/...
Condensed tannins (1−30 kDa), namely proanthocyanidins, are made up of polymers and oligomers of polyhydroxy flavan-3-ol and polyhydroxy flavan-4-ol subunits. Catechin and epicatechin are the flavom-3-ol constituents whereas leucoanthocyanidins belong to flavom-3,4-diol. Additionally, ...
FAEs play a key role in providing accessibility for glycoside hydro- lases and polysaccharide lyases to the lignocellulose fib- ers by removal of the ester-bonds between plant polymers [9, 10]. FAEs not only act synergistically with xylanolytic enzymes to convert xylan into its monomers, but ...
Differences are recognized in molecular weight, chemical nature of functional groups and of their core, which is organic in case of polymers and inorganic in case of nanomaterials. Moreover, in case of nanomaterials properties such as aspect ratio, geometry, and diameter could significantly alter ...
Let us start by describing some background information on protein structures. Proteins are complex polymers composed of a series of amino acids attached by peptide bonds. There are 20 different naturally occurring amino acids present in proteins, each with a different residual group, [R]: Sign in...
Copper-chalcogenide-based materials (nanosize and microsize) are another class of inorganic agents that can be used for photomedicine. The d-d transition of electrons results in an absorption band over 900 nm. Hu and co-workers first reported the synthesis of microsized flower-like CuS particle...
