5. Surface Chemistry Absorption and Adsorption – physisorption and chemisorption, factors affecting adsorption of gases on solids and liquids. Catalysis; homogenous and heterogenous, activity and selectivity, enzyme catalysis. Colloidal state distinction between true solutions, colloids and suspension; lyophi...
The section on the recent progress in the synthesis of well-defined functional polymer–protein conjugates aims to inspire new ideas for future contributions of macromolecular chemistry to the construction of materials derived from bio-(in)organic macromolecular building blocks. 2. Complexity and ...

This pushes electrons towards the secondary amine which in turn polarizes the carboxylate of Glu339, strengthening the H-bond with the meta-hydroxy group of DHB and increasing basicity. After deprotonation, this cluster acts as a proton-relay, before it is promptly broken and reordered to ...
To validate our design strategy, 4-oxyquinolines that lose a key hydrogen bond interaction with Asp1083 G9a (secondary amine was replaced by ether) were synthesized. The corresponding primary activity of one of such compounds, CM-1021, was reduced in more than 2.5 log units (Fig. 1a and ...
Finally, based on protein sequence alignment of the ACT, HCBT, and THTs, we suggest that ACT is a new class of the amineN-hydroxycinnamoyltransferases belonging to a diverse transferase family. EXPERIMENTAL PROCEDURES Plant Material Barley (H. vulgare L., cv. Triumph) was sown on top of ...

electrolyte exhibits a smooth and highly compact lithium deposit, without dendrite growth and obvious non-uniform volume expansion during the whole plating process (Fig.5cand Supplementary Movie13), once again confirming the good interfacial chemistry of the DMDOHD-based electrolyte with the Li-metal....
However, the formation of ionic centers via coordination chemistry is rare in this kind of polyelectrolytes. Fig. 1 Diverse topologies of metallo-polyelectrolytes. a metal ions attached to the side chain of organic polyelectrolytes through electrostatic interaction; b neutral metal complexes at the ...
