We have previously shown that CO2 stimulation of the renal Na-HCO3 cotransporter (NBC) activity is abrogated by general inhibitors of protein tyrosine kinases. The more selective inhibitor herbimycin also blocked this effect at concentrations known to preferentially inhibit Src family kinases (SFKs). We therefore examined a role for SFKs in CO2-stimulated NBC activity. To this end, we engineere...

This work investigates three types of biochar (bamboo charcoal, wood pellet, and coconut shell) for postcombustion carbon capture. Each is structurally modified through physical (H2O, CO2) chemical (ZnCl2, KOH, H3PO4) activation to improve capture performance. Three methods (CO2 adsorption isotherms, CO2 fixed-bed adsorption, thermogravimetric analysis) are used determine the capacity. The resu...

Sol-gel modification of mesoporous alumina membranes is a very successful technique to improve gas separation performance. Due to the formed microporous top layer, the membranes show activated transport and molecular sieve-like separation factors. This paper concentrates on the mechanism of activated transport (also often referred to as micropore diffusion or molecular sieving). Based on a theo...

In this study the effects of iron chloride (FeCl3) on the CO2 gasification kinetics of lower sulphur petroleum coke (PC) and sugar cane bagasse (SCB) via thermogravimetric analyser (TGA) were investigated. The FeCl3 loading effects on the thermal behaviour and reactivity of CO2 gasification of PC were studied. The possible synergistic interaction between the PC and SCB was also examined. Then t...

Herein we investigate computationally in detail the mechanism of the formation of the carboxylate adduct during the electroreduction of CO2 in water catalysed by cobalt porphyrin complexes. Specifically, we address qualitatively the competition between the concerted and sequential pathways for the proton-coupled electron transfer. We use a simple methodology for accurate computation of the pKa ...

BACKGROUND Low-level laser therapy (LLLT) with various types of lasers promotes fibroblast proliferation and migration during the process of wound healing. Although LLLT with a carbon dioxide (CO2) laser was also reported to promote wound healing, the underlying mechanisms at the cellular level have not been previously described. Herein, we investigated the effect of LLLT with a CO2 laser on fi...

In base-free CO2 hydrogenation to HCOOH over C3N4-supported Pd catalysts, a synergy between single atoms and nanoclusters has been discovered by observing the highest catalytic activity when an optimum ratio of two states is present in catalyst. It demonstrated that clusters are mainly involved H2 activation dissociative adsorption, while more effective for activation. Thus, at atom (number ato...

A low cost-biomass, olive stone, was used as a carbon precursor to synthesize activated biochar. Experiments were carried by single step activation for two agents (steam and CO2) using bench scale high-pressure thermobalance. Temperature, pressure, flow rate holding time optimized according the highest adsorption capacity of biochar obtained. In this respect, conditions established at 900 °C 30...

Catalysts for CO2-to-methanol are typically evaluated in a single-pass regime using pure CO2streams. In practical process however, CO shall be present as feed impurity or recycled byproduct. Herein, the sensitivity to was on In2O3 catalysts bulk, supported, metal-promoted forms, cycle experiments with variable CO2 and contents at H2/(CO + CO2) = 4. The methanol productivity decreased (?20-?40 %...
