The nitrogen compound semiconductor comprising Al is stable in scientific manner at a high temperature while easy to cause lateral growth compared to GaN, and a dislocation is further reduced to provide a flat-surface film 108. While introduced into the clad layer of a semiconductor laser element...
Most of us start learning about molecular structures in school. We are taught that we can draw structures comprising element symbols that we join together with lines and, later, that we can combine some groups in units, such as -CH3. At this stage of a science student’s education, space-...
Having sorted out ideas about elements and compounds in terms of atoms and molecules, attention shifted tosynthesis— the making of new compounds, and progress thereafter was rapid, especially in thechemistryof compounds containing the element carbon, what we call OrganicChemistry. It seems pertinent...
this article particularly focuses on the electronic structure regulation strategies employed to improve the intrinsic activity for three types of noble metal-free oxygen catalysts (i.e., transition metal compounds, single-atom catalysts (SACs), and metal-free catalysts) in alkaline electrolytes (Fig....

The reactivity of aluminium compounds is dominated by their electron deficiency and consequent electrophilicity; these compounds are archetypal Lewis acids (electron-pair acceptors). The main industrial roles of aluminium, and classical methods of synthesizing aluminium–element bonds (for example, hydroalu...
Overall, the drug resistance analysis of this conserved motif supports its role as a crucial structural element in Pdr5, and the PDR family. However, it also revealed a rather complex pattern that highly depends on the nature of the drug. The ATPase activity of these mutants was also ...
A wide variety of aromatic nitrogen compounds is found in the coals; no evidence of saturated amine is found. Pyrroles, pyridines, pyridones, and aromatic amines are found in coal; of these, pyrrolic structures are the most prevalent. Pyridine nitrogen is prevalent in all except low-rank ...
1B) (5). The nitroreductase family members, which are typically homodimeric enzymes, exhibits sequence variation and structural diversity. In particular, structural diversity is characterized by the insertion of an extension element into the central α + β fold at three different insertion sites (...
The compound structures were identified using spectroscopic techniques, including 1H and 13C NMR, along with X-ray diffraction. Furthermore, the electronic structures of the synthesized compounds were investigated through theoretical calculations using density functional theory (DFT) at the B3LYP/6-311G...
