Plant materials have significantly different biomass configuration which does not breakdown readily, due to the sturdy cell walls, perplexing the separation of ingredients within the matrix (Campbell et al., 2011). In addition, the presence of a plethora of compounds, from polysaccharide to phenols,...
While bronze mostly contains copper (87-88%) and tin (12-12.5%), other materials are often added to create a range of alloys with different properties. These materials could be metals (such as aluminum, manganese, or zinc) as well as nonmetals or metalloids (such as phosphorus or arsenic...
The hydrometallurgical processes in chloride media are particularly useful for zinc recovery from low-grade ores, complex sulfide ores, and also secondary zinc materials. In a number of processes, the extraction–stripping step is used for the purification and the concentration of zinc(II) chloride ...
Synthesis of high capacity cation exchangers from a low-grade Chinese natural zeolite The Chinese natural zeolite, in which clinoptilolite coexists with quartz was treated hydrothermally with NaOH solutions, either with or without fusion wit... Y Wang,F Lin - 《Journal of Hazardous Materials》 被...
PLURALITY OF HEAT ACCUMULATORS FOR HEAT ENERGY/COLD ENERGY ACCUMULATING SYSTEM PURPOSE: To minimize a loss of heat exchange between phase change materials and a heat exchange tube and to improve thermal efficiency, by connecting mutually a large number of heat accumulators charged with the phase ...
Fig. 1: Crystal structures of the starting materials bound to the two proteins. Shown are the compounds (magenta carbon atoms) and water molecules and amino acids from the proteins that are within 3.5 Å of the compound (with green carbon atoms) and with red oxygen, blue nitrogen and ...
MOF materials have been applied to the synthesis of membrane in recent years36–40. The main bot- tlenecks for the application of membrane are the high cost of membrane materials, and usually the separation performances of them have come up to short when characterized as thin membranes with ...
2. Materials and methods 2.1. Conversion methods The conversion of the concentration measurements of individual substances Ci to odour concentrations of the mixture COD and odour intensity OI is done by the four different methods briefly outlined in the introduction; the equations used are summarised ...
2.1. Materials All chemicals used in this work were of analytical grade and used without further purification for which details are given in Table 1. Choline chloride (ChCl) and sorbitol (S) with mass-basis purity > 0.99 were purchased from Solarbio and Sigma-Aldrich, respectively. Double-deio...
Knowledge of solvent phase behaviors is highly important to determine the attractiveness of using ionic liquids in these applications as well as in new applications such as absorption cooling or heating.Another need is a medium to store and transport volatile materials. Ammonia, for instance, is ...
