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-
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-...
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....
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...
Crystal structures of elements and inorganic compounds, as determined mainly by X-ray diffraction, are systematically reviewed, paying special attention to variable-pressure polymorphism. At ambient conditions, most metals have simple close-packed structures, elemental non-metals form open-framework or mol...

In the phase diagram of water, superionic ices with highly mobile protons within the stable oxygen sublattice have been predicted at high pressures. However, the existence of superionic ices and the location of the melting line have been challenging to d
Active and passive release of organic compounds from plant roots into the surrounding soil. Rhizosphere Zone surrounding plant roots in which the chemistry and microbiology are influenced by root activity. Root exudates A suite of substances that are secreted by the roots of living plants into the ...
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 three molecules are built on the basis of the same backbone formed by two aromatic rings (phenyl and triazole) linked by imine bridge. The two first compounds L1 and L2 contain tautomers of the Schiff base, where a phenyl ring is substituted by a bromine atom. The third one, L3, ...
