In this work, we used the bark of eucalyptus grafted with acrylic acid (EAA) as an adsorbent for removing Co2+ ions from aqueous solutions. EAA was characterized using Fourier Transformed Infrared Spectroscopy (FTIR), X-Ray diffraction (XRD), ... see more

The separation of ammonium bisulfate (ABS) from ammonium sulfate (AS) in aqueous solutions by monovalent ion selective membranes was studied. Optimised usage of these chemicals is both an important and challenging step towards a more efficient CO2 mineral... see more

This study was conducted in the framework of the PILOT CO2-DISSOLVED project, which provides an additional approach for CO2 sequestration, with the aims of capturing, injecting, and locally storing the CO2 after being dissolved in brine. The brine acidity... see more

A Monte Carlo simulation was performed for Co2+ in 18.6 % aqueous ammonia solution at a temperature of 293.16 K, using ab initio pair potentials and three-body potentials for Co-H2O-H2O, Co-NH3-NH3 and Co-H2O-NH3 interactions. The first solvation shell co... see more

Malaysia is anticipating an increase of 68.86% in CO2 emission in 2020, compared with the 2000 baseline, reaching 285.73 million tonnes. A major contributor to Malaysia’s CO2 emissions is coal-fired electricity power plants, responsible for 43.4% of... see more

O Bioma Amazônico vem sofrendo com a supressão de sua cobertura vegetal, alterando dessa forma o fluxo de carbono na interface solo-atmosfera. O desequilíbrio desse fluxo de carbono por sua vez altera as propriedades físicas e químicas do solo. Para verif... see more

The presence of phosphate in wastewaters can cause eutrophication of surface  water bodies leading  to algal-blooming  in the aquatic environment and degradation  of  water  quality.  Phosphate  removal  from&n... see more

Cap-rock integrity is an important consideration for geological storage of CO2. While CO2 bearing fluids are known to have reactivity to certain rock forming minerals, impurities including acid gases such as SOx, NOx, H2S or O2 may be present in injected ... see more

Hydroxyapatite, the main mineral phase of mammalian tooth enamel and bone, grows within nanoconfined environments and in contact with aqueous solutions that are rich in ions. Hydroxyapatite nanopores of different pore sizes (20 Å = H = 110 Å, where H is t... see more
