The title compounds are formed by reaction of DyI3, Dy metal and C in stoichiometric amounts in closed Ta ampoules, Dy10(C2)2I18 at 930 ◦C for 7 days, Dy4(C2)I6 at 950 ◦C for 6 days and Dy12(C2)3I17 at 900 ◦C for 11 days as pure samples according to X-ray powder diffraction. Dy10(C2)2I18 crystallizes in space group P21/c with a = 10.470(2), b = 17.152(3), c = 13.983(3) Å and β = 121.14(3)◦ , Dy...

This review article aims to describe the main applications of gas hydrates in industrial processes and related advantages limitations. In particular, storage, energy transportation, final disposal greenhouse gases, desalination, wastewater treatments, food concentration, other technologies are described detail. Similarly, benefits disadvantages solutions, currently adopted improve process effic...

Artificial photosynthesis, in which solar energy drives CO2 to produce hydrocarbon fuels, is considered an effective way solve the increasingly serious crisis and mitigate greenhouse effect. Herein, layered porous Ru-loaded La-doped g-C3N4 nanosheets (Ru-LGCNs) were prepared by one-step calcination, followed situ photoreduction deposition of Ru. The Ru-LGCN showed excellent photocatalytic refor...

To assess the role of cytochrome c2 as a respiratory electron carrier, we obtained a double mutant of Rhodobacter capsulatus defective in cytochrome c2 and in the quinol oxidase260. This mutant was able to grow chemoheterotrophically, indicating that an electron pathway independent of cytochrome c2 was functional between the ubiquinol:cytochrome c2 oxidoreductase and the cytochrome oxidase410.

Direct catalytic non-oxidative coupling is a promising route for the valorization of abundant methane. Understanding mechanism difficult because reactions at surface catalyst and in gas phase via radicals are important high temperatures employed. Herein, series Mo-doped CeO2 samples with isolated Mo sites were prepared by flame spray pyrolysis method screened their performance The selectivity t...

phytoremediation is an emerging green technology that uses plants and their associated microbes to remediate different environments contaminated with various pollutants. phytoremediation, as an effective soil remediation technology, has gained popularity in the past ten years both in developed and developing countries. the main goal of the current article is to improve the understanding of phyt...

Geochemical studies of gases from low-permeability reservoirs have raised new questions regarding the chemical and stable isotope systematics gas hydrocarbons. For instance, possibility thermodynamic equilibrium is recurrently in discussion. However, it not clear whether there anything “unconventional” way these systems continue to be studied. Using molecular carbon data North American unconven...

Waste cork granules of Quercus cerris bark were subjected to isothermal and non-isothermal slow pyrolysis. The heat the reaction, as well yields properties biochar, bio-oil, pyrolysis gas investigated by thermogravimetric analysis, FT-IR, CHN elemental higher heating value (HHV) determinations, scanning electron microscopy (SEM), chromatography (GC). was carried out in a semi-batch reactor usin...
