The Fries rearrangement reaction is the synthesis of o- or para-acyl phenols from phenolic esters catalyzed by Lewis or Brønsted acids (e.g., HF, AlCl3, BF3, TiCl4, or SnCl4).The Fries rearrangement reaction was first reported by the German chemist Karl Theophil Fries, after whom it was named, ...
Sulfonyl chlorides and sulfonamides are organic compounds containing sulfonyl groups , which are rich in chemical reactivity and diverse chemical structures and are therefore widely used in synthetic chemistry and medicinal chemistry, among other fields.
Alzheimer's disease is one of the most common neurodegenerative diseases in the world. The clinical manifestations are extracellular amyloid plaques and intracellular neurofibrillary tangles that lead to neuronal dysfunction and cell death. At the heart of the disease is differential processing ...
The formation of mutations and the development of cancer both involve damage to a cell's DNA. DNA in human cells is damaged thousands to millions of times a day by both external (exogenous) and internal metabolism (endogenous). Changes in a cell's genome can lead to errors in the transcription ...
lithium- ion batteries are being widely used in power fields such as portable electronic devices, electric vehicles, and large-scale energy storage power stations [1-3]. With the transformation of the energy structure and the upgrading of large electrical equipment, lithium-ion batteries have ...
Lithium- ion batteries (LIBs) are widely used in a wide range of applications due to their high energy density, high Coulombic efficiency, low self-discharge characteristics, and a range of chemical potentials obtainable with different electrode designs. With the rapid development of people's ...
The past two decades have seen breakthroughs in understanding molecular biology, genomics, and nanotechnology. The intersection of these three disciplines has opened up a new field of research - bionanotechnology and nano biomedical technology.
various fields ranging from biomedical engineering to photovoltaic power generation. Most applications take advantage of the excellent optical properties of gold nanoparticles, which can be fine-tuned by changing their shape and size.
Albumin is the most important protein in human plasma and plays an important role in maintaining blood volume and body fluid balance. It is a spherical simple protein soluble in water and coagulated with heat. Its molecular structure was clarified in 1975. It is a single-chain polypeptide with ...
Friedel–Crafts Acylation reactions are a class of reactions in which aromatic hydrocarbons are acylated with chlorides or anhydrides under the conditions of Lewis acids as catalysts. This reaction generally does not produce multiple acylation products like alkylation reactions due to the ...
