Chemical modification is the change of biomolecular structure and function due to the addition or removal of modifying elements. [1] This is usually accomplished via chemical reactions or a series of chemical reactions that may or may not be reversible. Chemical modifications can be done to any of the four major macromolecules (proteins ...
Surface modification. Surface modification is the act of modifying the surface of a material by bringing physical, chemical or biological characteristics different from the ones originally found on the surface of a material. [1] This modification is usually made to solid materials, but it is possible to find examples of the modification to the ...
Cloud seeding is a type of weather modification that aims to change the amount or type of precipitation, mitigate hail or disperse fog. The usual objective is to increase rain or snow, either for its own sake or to prevent precipitation from occurring in days afterward.
Chemically modified electrode. A chemically modified electrode is an electrical conductor that has its surface modified for different electrochemical functions. Chemically modified electrodes are made using advanced approaches to electrode systems by adding a thin film or layer of certain chemicals to change properties of the conductor ...
In molecular biology, post-translational modification (PTM) is the covalent process of changing proteins following protein biosynthesis. PTMs may involve enzymes or occur spontaneously. Proteins are created by ribosomes, which translate mRNA into polypeptide chains, which may then change to form the mature protein product.
Carbon nanotube chemistry involves chemical reactions, which are used to modify the properties of carbon nanotubes (CNTs). CNTs can be functionalized to attain desired properties that can be used in a wide variety of applications. [1][2][3][4][5] The two main methods of CNT functionalization are covalent and non-covalent modifications. [6]
Biotransformation is the biochemical modification of one chemical compound or a mixture of chemical compounds. Biotransformations can be conducted with whole cells, their lysates, or purified enzymes. [1] Increasingly, biotransformations are effected with purified enzymes. Major industries and life-saving technologies depend on ...
Westwood is the most advanced modern thermo-modification process, patented in 2004. The process has initially developed for treatment hardwoods, which are more complicated compared to softwoods due to thermo-chemical reactions appeared in hardwoods during thermo-treatment.
