Georgiou, Panagiotis G.;Marton, Huba L.;Baker, Alexander N.;Congdon, Thomas R.;Whale, Thomas F.;Gibson, Matthew I. research published 《 Polymer Self-Assembly Induced Enhancement of Ice Recrystallization Inhibition》, the research content is summarized as follows. Ice binding proteins modulate ice nucleation/growth and have huge (bio)technol. potential. There are few synthetic materials that reproduce their function, and rational design is challenging due to the outstanding questions about the mechanisms of ice binding, including whether ice binding is essential to reproduce all their macroscopic properties. Here we report that nanoparticles obtained by polymerization-induced self-assembly (PISA) inhibit ice recrystallization (IRI) despite their constituent polymers having no apparent activity. Poly(ethylene glycol), poly(dimethylacrylamide), and poly(vinylpyrrolidone) coronas were all IRI-active when assembled into nanoparticles. Different core-forming blocks were also screened, revealing the core chem. had no effect. These observations show ice binding domains are not essential for macroscopic IRI activity and suggest that the size, and crowding, of polymers may increase the IRI activity of “non-active” polymers. Poly(vinylpyrrolidone) particles had ice crystal shaping activity, indicating this polymer can engage ice crystal surfaces, even though on its own it does not show any appreciable ice recrystallization inhibition. Larger (vesicle) nanoparticles are shown to have higher ice recrystallization inhibition activity compared to smaller (sphere) particles, whereas ice nucleation activity was not found for any material. This shows that assembly into larger structures can increase IRI activity and that increasing the “size” of an IRI does not always lead to ice nucleation. This nanoparticle approach offers a platform toward ice-controlling soft materials and insight into how IRI activity scales with mol. size of additives.
5445-17-0, Methyl 2-bromopropionate, also known as Methyl 2-bromopropionate, is a useful research compound. Its molecular formula is C4H7BrO2 and its molecular weight is 167 g/mol. The purity is usually 95%.
Methyl 2-bromopropionate is used in the synthesis of poly(ADP-Ribose)polymerase inhibitors derived from benzoxazin-3-one. Also used in the synthesis of 5-HT2C antagonists affecting serotonin levels.
Methyl 2-bromopropanoate is a chemical compound that can be synthesized in an asymmetric manner. The reaction of methyl 2-bromopropanoate with hydrochloric acid gives the corresponding carboxylic acid, methyl propanoate, and hydrogen bromide in a 1:1 ratio. It has been shown that methyl 2-bromopropanoate is a potential catalyst for the reduction of chloride to chloride ion via the borohydride reduction method. Methyl 2-bromopropanoate has also been used as a model system for studying halides and copper complexes. Magnetic resonance spectroscopy studies have revealed that this chemical compound has a high redox potential and kinetic properties., Reference of 5445-17-0
