Computers can be very helpful to us by performing tasks on our behalf. For example, they are very good at performing calculations, storing information and producing visualisations of objects that do not yet exist as a made artifact. Increasingly, however, a different role is being found for the computer. It is the role of a catalyst, or a stimulant, to our own creative thinking. In such cases t...

Electro-osmosis in clayey soils and sediments, for purposes of clay consolidation, dewatering, or cleanup, and electro injection in porous media is widespread recent decades. It is experimentally found that the chemical properties of porous media especially PH change the characteristics of media. Electro-osmotic conductivity is a function of soil and grout material chemistry, altering with time...

A simple and efficient synthesis of aryl and heteroaryl substituted pyrimidines has been developed via initial Knoevenagal, subsequent addition and final cyclization of aldehyde, ethylcyanoacetate and guanidine nitrate. Piperidine has been used as a catalyst. Short reaction time, environment friendly procedure and excellent yields are the advantages of this procedure. All synthesized compounds ...

Catalyst selectivity is associated with well-defined homogeneous active sites. Transition metal complexes and organocatalysts are highly active and selective in the homogeneous phase, and their heterogenization by incorporating them into inorganic solid materials allows combining their excellent catalytic activity with improved separation, recovering and recycling properties. In this article, w...

An iron single-atom catalyst, composed of robust FeN 4 moieties anchored on a nitrogen-doped porous carbon matrix (Fe-SAC/NC), has been developed via surfactant-coordinated metal-organic framework (MOF) approach for application in heterogeneous electro-Fenton (HEF) process. The cohesive interaction between the surfactant and MOF precursor enabled formation abundant stable moieties. Fe-SAC/NC-ca...

background: although stabilization ponds and lagoons are suitable treatment processes due to simplicity of operation and low per capital costs, the effluents of these systems have too high of a total suspended solids concentration to be discharged into receiving waters. this problem is mainly caused by algae. in this study, an electro-coagulation reactor was examined to re­move algae from the f...

we explore electro-catalytic properties of a system consisting of platinum and palladium nanoparticles dispersed over a nanotubular self-organized tio2 matrix. these electrodes prepared by electroess and microemulsion of palladium and palladium nanoparticles on to tio2 nanotubes, respectively. titanium oxide nanotubes were fabricated by anodizing titanium foil in ethylene glycol (eg) fluoride-c...
