Crystallization of frustrated alkyl groups in polymeric systems containing octadecylmethacrylate

open access: yes, 2022
S.201-228This chapter deals with the crystallization behavior of long frustrated alkyl groups as part of side chain polymers. Results from crystallization experiments on poly(n-octadecylmethacrylate) [PODMA] homopolymers with different molecular weight ...

Interfacial Crystallization within Liquid Marbles

open access: yesCondensed Matter, 2020
We report interfacial crystallization in the droplets of saline solutions placed on superhydrophobic surfaces and liquid marbles filled with the saline. Evaporation of saline droplets deposited on superhydrophobic surface resulted in the formation of cup-

Self-interaction chromatography as a tool for optimizing conditions for membrane protein crystallization [PDF]

open access: yes, 2010
The second virial coefficient, or B value, is a measurement of how well a protein interacts with itself in solution. These interactions can lead to protein crystallization or precipitation, depending on their strength, with a narrow range of B values ...

Understanding the Reaction Crystallization Process of Glycidyl Trimethyl Ammonium Chloride

open access: yes, 2021
Reaction crystallization to produce glycidyl trimethyl ammonium chloride (GTA) via epichlorohydrin with gas-state trimethylamine was investigated. The crystallization process of the GTA gas-liquid reaction was optimized by a seed method.

Scientific problem of modifying of primary crystals a -phase of silumin castings. Solutions

open access: yesЛитьë и металлургия, 2019
It is shown that intermetallic metals of the modifying ligatures are not the crystallization centers of primary crystals of a a-phase. As the main demodifier serves hydrogen dissolved in liquid silumin.

Expression, purification, crystallization and preliminary X-ray analysis of ORF60, the small subunit (R2) of ribonucleotide reductase from Kaposi's sarcoma-associated herpesvirus (KSHV) [PDF]

open access: yes, 2010
Ribonucleotide reductase (RNR) is responsible for converting ribonucleotides to deoxyribonucleotides, which are the building blocks of DNA. The enzyme is present in all life forms as well as in some large DNA viruses such as herpesviruses.

EXPERIMENTAL DETERMINATION OF THE RATES OF NUCLEATION AND OF GROWTH OF PHASE TRANSFORMATION CENTERS

open access: yesТонкие химические технологии, 2016
The processes of granulation by crystallization of molten droplets in the flow of a cooling agent (prilling) and on the cooled surfaces of the granulators are widely used in the chemical and allied industries. The process of granulation (crystallization)
