Chemistry of Acetalsβ-Ethoxyacrolein, β-ethoxy-α-methylacrolein, β -ethoxy-α-amylacrolein, the sodium enolate of malonic dialdehyde, bromomalonic dialdehyde, and octatrien-2,4,6-dial-1,8 were reduced at a dropping mercury electrode. The reduction waves had diffusion character....
The measurements performed with the use of the same preparation of lipid vesicles with incorporated SpaR (analogously experiments with ESR141 and heliorhodopsin142) were reproducible and showed the analogous character and amplitudes. Confocal fluorescent microscopy...
The proposed π-type character of the central C–C bond of BCBs has led to suggestions that it could also take part in cycloaddition-type chemistry. Importantly, an alkene insertion or [2σ-2π]-type reaction would lead to the formation of bridged bicyclic bicyclo[2.1.1]hexane (BCH) ...
The resistances have an ohmic character (i.e. the current-voltage dependence is linear). A huge advantage of the BLM model is that possibly all the functional membrane proteins, including membrane ionic channels, transporters, pharmaceuticals and toxins, can be incorporated into this model system ...
The Mo–S bonds (Mo–S: 2.43 Å) within the layers are covalent and in the trigonal-prismatic ligand field, a two-electron band of mainly dz2 character is separated from the main part of the Mo 4d band and hybridizes strongly with the S 3p band. The dz2 band is completely filled...
these compounds show a complex diversity of behavior that is primarily characterized by their aliphatic or aromatic character and the presence of other functional groups. Nevertheless, the introduction of chlorine atom(s) into a hydrocarbon significantly influences its physicochemical and biochemical properti...
Other ligands led to unreactive dimers – formally of zirconium(iii). The π-ligand was a Goldilocks solution – just enough stabilisation and just enough zirconium(ii) character. Any π-ligand? Well, no. Cp2ZrII-alkyneη-complexes (like Erker’s) always incorporate the ligand in the product...

The main specific problems to be addressed in cementitious materials are related to physical durability of microencapsulated pigments upon the highly demanding mixing and casting procedures, as well as to the chemical aggressiveness of the highly alkaline character of the cementitious matrix. In the ...
