A gas is found to obey the equation of state given byP= RT - a--- ---V-b VWhere a and b are constants but not equal to zero.Determine whether this gas a critical point.If it does,express the critical constants in terms of a and b.If does not explain why.A cloud mass moving...
In general, fluidised bed gasifiers allow a high and uniform heat and mass transfer between the solid biomass and the gasifying medium, which allows good mixing and contact that increase the reaction rates and conversion efficiencies, minimising tar and char production (together with biomass ...
This relationship would show which experimental condition (T and t) led to the higher specific methane production, i.e., methane accumulation in relation to the incubated mass of substrate. Eq. (4) describes the behavior of the response variable methane production capacity (kg TOC Nm3 CH4−1...
Evolution has resulted in the development of a robust immune system, which can serve as a source of inspiration and template for the exploration of emerging and innovative strategies for tumor therapy. Neutrophils are the first line of defense of the innate immune system1, and play an important ...
Web spiders connect silk proteins, so-called spidroins, into fibers of extraordinary toughness. The spidroin N-terminal domain (NTD) plays a pivotal role in this process: it polymerizes spidroins through a complex mechanism of dimerization. Here we analy
8. A process according to claim 1, wherein the catalyst is subjected to a reduction before use, said catalyst reduction being performed by contact with a mixture of inert gas with at least one reducing compound in a molar ratio "reducing gas/inert gas+reducing gas" from 0.001:1 to 1:1...
1.A process for making one or more unsaturated oligomeric acids comprising:oligomerizing one or more unsaturated carboxylic acids having from 4 to 38 carbon atoms in the presence of a catalyst,wherein the catalyst is a molecular sieve, andwherein the one or more unsaturated oligomeric acids comp...
Fossil fuels have been the most employed energy source with a consistent and growing consumption; however, they will be replaced by renewable energy sources (RESs). Massively using this type of energy will require new materials, especially metallic-based
The Cu5.4O USNP storage solution from a specific time point was added to 2 mM of H2O2 solution in the dark. The absorbance at 550 nm was measured 2 h later. A mixture with water instead of Cu5.4O USNPs was used as a control (n = 3). All the solutions used were freshly prepared...
Chromatographic separations were carried out using DB-1701 column with 30 m length, 0.25 mm internal diameter, and 0.25μm column phase thickness. Injection mode was splitless while helium was used as a carrier gas, and 1 μl volume of the sample was injected to the inlet heated to 275 ...
