The nature of the premelted surface layer, its structure, thickness and how the layer changes with temperature have been debated for over 160 years, since Faraday first postulated the idea of a quasi-liquid layer on ice. Here, we briefly review current opinions and evidence on premelting at ...
An acid-salt mixed solution (0.1 mol/L HCl and 0.1 mol/L CuSO4) is used to clean and structure the aluminum substrate for 5–10 min so that micro and nanostructures can be formed. The structured aluminum substrates are immersed into an ethanol solution of 1 wt.% fluoroalkyl ...
acid H2CO3(carbonic acid); but both sulfuric and nitric acids are strong acids and their impact on the pH of rainwater is far greater for a given molar quantity dissolved than is that of carbonic acid. Because of their presence, the average pH of rainfall in the northeastern United States...

Because the carbon dioxide-free attribute requires post-production protection from the atmosphere, it is appropriate to first render the water ammonia-free using the High Purity Water process followed by the boiling and carbon dioxide-protected cooling process. The High Purity Water deionization process...
Gd2O3). Because of the boiling in the tank boric acid cannot be used for reactivity control; however, it is provided as an extra emergency shutdown feature. The control blades contain boron carbide rods or powder placed in channels in the stainless steel blade-wings. In addition to negative...
Secondly, ethylenediamine tetra-acetic acid di-anhydride was mixed with a solution of N, N-dimethylacetamide containing yeast crosslinked biomass that was prepared in the first step. Subsequently, the mixture was washed to remove the unreacted reagent after being stirred for 4 h at 60 °C and ...
The researchers observed a striking difference in the amino acid composition between the crystals and the meteorites in which they were found, indicating both came from separate origins. They suspected that the crystals were ejected into space by ice- or water-spewing volcanic activity on Ceres, a...
Finally, a genome was considered to have broad metabolic capacity (carbon fixation) if any relevant KEGG module was present (CBB pathway, 3HP cycle, 3HP/4HB cycle, Wood Ljungdahl pathway or reverse tricarboxylic acid cycle). The results from METABOLIC for each site are provided in Supplementary...
An antifreeze concentrate comprising an alcohol, buffer, silicate, and a silicate protecting agent comprising an alkane tetracarboxylic acid, preferably a 1, 2, 3, 4-alkane tetracarboxylic acid, and d
