The MgCl2?NH3 reactive system is investigated in terms of heat and mass transfer coupled with chemical reaction through numerical simulation. reversible nature the captured by including adsorption desorption rate expression simultaneously. kinetic coefficients are directly adopted from literature, while those for calculated based on thermodynamic relations. impact changing pressure pellet poros...

The reaction pathways and kinetics for the selective deposition of palladium on copper from the metalorganic precursor Pd(hfac)2 have been established by means of reactive molecular beam-surface scattering where a flux of Pd(hfac)2 (ranging from 1013 to 1014 molecules cm-2 s-1) impinges continuously on the copper surface. The surface selectivity of the deposition process is a consequence of a “...

Coal and gas outburst is an urgent constantly perplexing problem with coal resource extraction, threatening mine safe sustainable production severely. Its mechanism the participation of in breaking are still unclear. To explore this problem, paper, desorption-diffusion regularity bituminous different particle sizes its influence on outburst-coal were investigated through mercury intrusion poros...

High entropy alloys belong to a new and promising class of functional materials for solid-state hydrogen storage. In this context, novel single-phase body centered cubic (bcc) high alloy Ti0.30V0.25Zr0.10Nb0.25Mo0.10 was prepared. The physicochemical sorption properties have been determined by both laboratory large-scale facilities. This can quickly absorb up 2.0 H/M (2.8 wt.%) at room temperat...

Food wastes have traditionally been considered as dead-end materials; however, recent international, national, and regional policies strongly promote the use of these potential resources. This change perception considers need for sustainable exploitation natural In this context, artichoke processing produces high amounts wastewaters, specifically, wastewaters from blanching step present a conte...

In this study, two types of modified cassava starch samples (MCS and MWS) prepared from commercially available native (NCS) extracted using the wet method (NWS) were investigated for removal Pb(II) ions aqueous solutions. MCS MWS synthesized under acidic conditions Pluronic 123 as structure-directing agent tetraethylorthosilicate (TEOS) chemical modifying agent. Modified characterized Fourier t...

Release of sorbed phosphate from ferric iron oxyhydroxides can contribute to excessive algal growth in surface water bodies. Dissolved silicate has been hypothesized facilitate desorption by competing for mineral sites. Here, we conducted and adsorption experiments with goethite under a wide pH range (3–11), both individually (P or Si) simultaneously plus Si). The entire experimental data set w...

chemical stabilization of heavy metals is one of the soil remediation methods based on the application amendments to reduce mobility of heavy metals. a laboratory study was conducted to investigate the influence of different kinds of amendments on cadmium (cd) stabilization in a cd-spiked soil. the amendments were municipal solid waste compost (mswc), coal fly ash (cfa), rice husk biochars prep...
