Using zeolite-rich tuffs for improving soil properties and crop N-use efficiency is becoming popular. However, the mechanistic understanding of their influence on N-processes still poor. This paper aims to shed new light how natural NH4+-enriched chabazite zeolites alter short-term N-ammonification nitrification rates with without use inhibitor (DMPP). We employed 15N pool dilution technique de...

Results are presented from 1 year batch experiments where K-rich hyperalkaline pH 13.5 young cement water (YCW) was reacted with sediments to investigate the effect of high pH, mineral alteration, and secondary mineral precipitation on (90)Sr sorption. After reaction with YCW, Sr sorption was found to be greater than 75% in all samples up to 365 days and 98% in a sample reacted for 365 days at ...

Artificial carbon dioxide capture is an alternative method to remove the already accumulated in atmosphere as well stop its release at large-scale emission points source, such power plants. However, new adsorbents are needed make approach feasible. For this purpose, study, hierarchical mesoporous-microporous chabazite-type zeolites were synthesised by applying a dual-templating method. The micr...

ABSTRACT Located in the southwest corner of Ratanakiri Volcanic Province, Wat Ocheng basalt is first known zeolite locality Cambodia. The a fine-grained, vesicular to amygdaloidal, subalkaline transitional alkaline intraplate tholeiite comprised 30% lath-like plagioclase (average: Ab51An45Or4), 35% interstitial augite Wo44En35Fs21), 25–30% zeolites after and volcanic glass, minor skeletal ulvös...

ine"> Chabazite zeolite membranes were synthesized for their potential application in dehydration of natural gas. The membranes were prepared using secondary growth method on porous <span styl...

The adsorption of alkanes in a protonated zeolite has been investigated at different levels of theory. At the lowest level we use density-functional theory (DFT) based on semi-local (gradient-corrected) functionals which account only for the interaction of the molecule with the acid site. To describe the van der Waals (vdW) interactions between the saturated molecule and the inner wall of the z...
