The adsorption structures of oxygen and sulfur are compared for both ordered and disordered phases as determined by means of LEED and DLEED, respectively. Emphasis is on the comparison of the different chemical species as well as on the coverage dependence in each case. In the ordered phases ...
SULFUR ISOTOPE EXCHANGE AND METAL ENRICHMENT IN THE FORMATION OF MAGMATIC Cu-Ni-(PGE) DEPOSITS Thin poly(phenylene sulphide) foils were bombarded with fast atomic ions (He-4, C-12, O-16, S-32, Br-79, I-127) in the energy range between 2.5 to 78 MeV. ... EM Ripley - 《Economic ...
4. The small canyon is a perfect place for scientific expedition and education, and also a natural oxygen bar and summer resort with lush vegetation. 5. The environmental protection index will include capital input in the areas of environmental protection, annual sulfur dioxide emission and chemical...

The development of highly active air-cathodes with robust stability and a low price is of crucial significance for rechargeable Zn–air batteries and remains a great challenge. Herein, for the first time, we report a “rigid and flexible” material consi
Oxygen has an oxidation state of −2 in most of its compounds. It forms a large range of covalently bonded compounds, among which are oxides of nonmetals, such as water (H2O), sulfur dioxide (SO2), and carbon dioxide (CO2); organic compounds such as alcohols, aldehydes, and carboxylic...
achieved a lower onset overpotential of 280 mV, and the interesting enhancement in OER activity was due to lower charge transfer resistance, which resulted in a lower Tafel slope (Fig. 9c–h). The excellent activity toward the OER due to a reduced size in terms of QDs andsulfur vacancies...
Substitutional Coinage Metals as Promising Defects for Adsorption and Detection of Gases on MoS 2 Monolayers: A Computational Approach Defective molybdenum disulfide (MoS2) monolayers (MLs) modified with coinage metal atoms (Cu, Ag and Au) embedded in sulfur vacancies are studied at a disp... J ...
[63]synthesized sulfur-doped TiO2materials using theoxidationannealing method of titanium disulfide (TiS2). Oxygen vacancies were generated in the annealing process, which made TiO2show a red-shifted absorption edge. Li et al.[64]constructed orthogonal-monoclinic WO3phase junctions with oxygen ...
