Catalytic direct (hetero)arylation of (hetero)arenes is an attractive alternative to traditional Kumada, Stille, Negishi and Suzuki-Miyaura cross-coupling reactions, notably as it avoids the prior preparation and isolation of (hetero)arylmetals. Developments of this methodology in the oxazole series are reviewed in this article. Methodologies, selectivity, mechanism and future aspects are prese...

Effects of d-doping on barriers effective heights and series resistance of highly doped n-type GaAs/AIAs/GaAs/AlAs/GaAs heterostructures, grown by molecular beam epitaxy (MBE) at 400?°C, have been studied. As it was expected, inclusion of an n+ d-doped layer at each hetero-interface has reduced the barriers heights and series resistance of the structure significantly, while p+ d-doped layers ha...

A large fraction of the proteome is made by proteins that are not permanently monomeric but form oligomeric assemblies, which can be either homo- or hetero-oligomeric. Here it is described that protomers of hetero-oligomeric proteins tend to resemble each other more than expected. This is verified by comparing the level of similarity of pairs of hetero-oligomeric protein protomers and of pairs ...

A Hetero Dielectric Tunnel field effect transistor with the spacer on both sides of gate is proposed in this paper. The performance and characteristics using ATLAS Technology Computer-Aided Design 5nm regime were analyzed. band-to-band tunneling leakage current will be reduced by introducing heterojunction hetero dielectric material structure. In transistor, double metal high-k improves high su...

CeO2 and Y2O3-stabilized zirconia (YSZ) are two typical candidates for electrolyte materials in solid oxide fuel cells attributed to their high ion conductivities. However, the conductivities of these materials are closely connected with high temperatures. Therefore, it is important to develop electrolyte materials which can conduct oxygen ions at lower temperatures. Recent experiments have sho...

Donor-acceptor strategy is employed for designing low band gap hetero-aromatic copolymers using an artificial intelligence mechanism, viz., particle swarm optimization. The investigated structures include hetero-aromatic donor moieties, viz., pyrrole, thiophene and furan in combination with carbonyl and dicyanomethylene acceptor groups. The electronic properties of all the possible donor and ac...

Sirtuin 1 (SIRT1) is a nicotinamide adenine dinucleotide-dependent deacetylase, and its dysregulation can lead to ageing, diabetes, and cancer. From 346 experimentally confirmed SIRT1 inhibitors, an inhibitor structure pattern was generated by inductive logic programming (ILP) with DMax Chemistry Assistant software. The pattern contained amide, amine, and hetero-aromatic five-membered rings, ea...

Phosphorescence in ethanol and n-pentane at 77 K of the benzologues 1-8 of furan, thiophene, selenophene and tellurophene has been investigated. The rate constants of both the radiative (A.PT) and non-radiative (A:GT) deactivation of the lowest triplet state correlate linearly with X cl C2 where ck denotes the Hückel AO coefficients in the HOMO of the carbon atoms bound to the hetero-atom and (...
