Silicon (Si) is one of the most abundant elements in the Earth’s crust, second only to oxygen. In nature, silicon mainly exists in inorganic forms such as silicates and silicon dioxide, found in rocks, sand, crystals, glass, and ceramics. For thousands of years, humans have utilized inorganic ...
Carotenoids are a large family of fat-soluble natural pigments widely distributed in nature. They impart yellow, orange and red hues to plants, algae, and certain microorganisms and animal tissues. From a chemical perspective, most carotenoids are C₄₀ polyene compounds composed of 40 carbon ...
The performance of conventional devices is often limited by the intrinsic properties of the underlying materials (such as intrinsic carrier concentration, bandgap, thermal conductivity, etc.). Once we enter the nanoscale, device performance is no longer determined solely by what the material is; ...
During cell lysis, tissue homogenization, and protein extraction, endogenous proteases and protein phosphatases are rapidly activated and brought into full contact with target proteins. This leads to protein degradation and the rapid loss of phosphorylation and other post-translational ...
ADME/Tox: From Basics to Advanced – Metabolizing Enzymes, Transporters and Key Tool Compounds
In a broad sense, any chromophoric system that absorbs light at a shorter wavelength and re-emits it at a longer wavelength is referred to as a fluorophore. A major subgroup consists of small-molecule fluorescent dyes, but fluorophores also include fluorescent proteins and various ...
In organic synthesis, organometallic catalysis, electrochemistry, photolithography, and functional materials, one frequently encounters the abbreviations “TfOH”, “OTf”, “triflate”, and “triflic”. All of these are closely associated with trifluoromethanesulfonic acid (CF₃SO₃H, ...
Polyethylene glycol (PEG) is a hydrophilic polymer composed of repeating –CH₂–CH₂–O– units. Owing to its excellent water solubility, low toxicity, low immunogenicity, and good biocompatibility, pharmaceutical-grade PEG has been widely used in injectable formulations, ...
Polyvinyl chloride (PVC) is a widely used general-purpose thermoplastic resin that combines good mechanical strength, chemical resistance, electrical insulation, and a certain level of flame retardancy. By adjusting additives such as plasticizers, stabilizers, and fillers in the formulation, PVC ...
