Nitrogen oxides (NOx) contribute much to acid rain, photochemical smog, and the depletion of tropospheric ozone. In China, the total amount of NOx emission has been controlled during the National Twelfth Five-Year Plan. The commercial technology for NOx control is the selective catalytic reduction (SCR) of NOx with NH3. Therein, the SCR catalyst is the most important. Previous studies have showed that a lot ofamor...

Ferromanganese minerals occurred in soils, sediments and sea floor are generally enriched in various transition metals (TMs). Hexagonal birnessite is the most ubiquitous and reactive manganese oxide in geological environments. Incorporation of TM ions into birnessites not only affects their valence and speciation, but also results in certain changes in (sub)structure and physicochemical properties, consequently af...

Ceria nanoparticles(NPs)aregenerally recognized as stable under environmental and biological conditions,and are unlikely to release heavy metal ions. Their research has been published on an important journal in nanoscience,ACS Nano(Biotransformation of ceria nanoparticles in cucumber plants. This is the first report confirming the biotransformation of ceria NPs in biological systems This implies that in the assess...

Metallic glasses have been extensively researched due to its special structure and properties. However,the electronic structure of the metallic glasses remains unclear. The team draws a conclusion that the polyamorphic transition in the lanthanide BMGs inherits from solvent component’s crystalline polymorphic transitions related to the 4f electronic state The compressive behavior of pure rare-earth under high pre...

GMS exhibits the representative supramolecular structure of two-dimensional(2D)hydrogen-bonded bilayered motifs under ambient conditions(Figure 1). Figure 1 Crystal structure of GMS under ambient conditions Figure 2 summarizes the evolution of the lattices modes of GMS. Figure 1A.Crystal structure of SS under ambient conditions. 1B Crystal structure of SST under ambient conditions From the representative Raman and...

The interfaces between metals and polymers are of considerable importance in wide-ranging applications, especially in optoelectronic devices, packing, and coatings, because metal layers are usually deposited on polymer films as key functional components (e.g., electrodes and coatings). Therefore, a thorough understanding of the nature at the interfaces between metals and polymers can provide important guidance for...
