The fluorine-containing epoxy resin composition of the present invention comprises a fluorine-containing epoxy resin having in one molecule at least one perfluoroalkyl group having 6 to 12 carbon atoms and at least two alicyclic epoxy groups, and a cationic polymerization catalyst....
A +1 B +2 C +3 D +6 3 When considering one molecule of ethene, which row describes both the hybridisation of the atomic orbitals in the carbon atoms and the overall bonding? hybridisation bonding A sp2 4 σ bonds 1 π bond B sp2 5 σ bonds 1 π bond C sp3 4 σ bonds 1 π ...
It most likely is due to that the “C” (in -CF2-) is sp3 hybrid, while the “O” from the “-O-” linker is sp2 hybrid, resulting in a slight change of the shape of the molecule along with the changes of the electron density around the war-head and the conformation of the ...
Molecule for molecule, many of these other gases cause more warming than carbon dioxide does—in the case of methane, 120 times more warming the moment it reaches the atmosphere. But methane doesn’t stay around as long as carbon dioxide. Ultimately, what really matters isn’t the amount of...
Exchange reaction (imidization without water molecule elimination). 7. Polymerization of dianhydrides and diisocyanates. 8. Cycloaddition reaction (Diels-Alders reaction of bismaleimides). 9. C–C coupling reaction. In today's world where science and technology are rapidly developing, focusing on all...
2015). In addition to the above-mentioned tomato lectin-invasin complex, conjugated lipopolysaccharide (LPS), a molecule found on the outer layer of gram-negative bacteria, a pathogen-associated molecular pattern (PAMP) recognized by host cells, can boost particle uptake. LPS is recognized by ...

Silane is a multi-functional molecule which is used as a coupling agent to modify fiber surfaces. The composition of silane forms a chemical link between the fiber surface and the matrix through a siloxane bridge [Citation35]. Silane treatment improves the physico-chemical properties and tribologica...
The central premise of medical chemistry is that a specific small molecule can bind to the desired enzyme or receptor, which results in a specific therapeutic effect. The aforementioned inhibition process can also be achieved using nucleic acid therapies including a technique called RNA interference (...
Using recombinant protein, we show that HIPKs phosphorylate general components of the transcription machinery, such as c-Myc, SPT5, and the RNA pol II C-terminal domain (CTD). Based on a database screen for potential selective HIPK inhibitors, 15 ATP-competitive small-molecule compounds were ...
