Background & Aims of the Study: Azo Dyes are the most hazardous materials in different industries. Dyes and pigments used in industries for applications such as textiles, leathers, papers, foodstuffs, additives, etc. Application amounts of azo dyes in industries which can cause severe health problems in human and environmental pollutant problems. So, color wastewaters decomposition plan are...

In this study, the amount of photocatalytic degradation perchloroethylene in gas phase was investigated by a fixed bed continuous-flow tubular photoreactor. The photoreactor consists cylindrical glass tube, filled with beads coated nanoparticles TiO2, TiO2 doped carbon (TiO2-C). These were synthesized sol-gel method and deposited on using dip technique. X-ray diffraction (XRD), scanning electro...

The Front Cover illustrates the 3D-printed photoreactor, in which benchmark reaction, specifically an sp2–sp3 cross-electrophile coupling, is performed. reactants enter reactor and product released under blue light irradiation. More information can be found Article by Florian Schiel co-workers.

Cryptosporidium parvum and Giardia lamblia are two of the most chlorine resistant microorganisms with notable adverse effects on humans. Our study shows that waters containing these two protozoa at low concentrations can be efficiently disinfected in continuous flow by using a commercial fibrous ceramic TiO(2) photocatalyst. The efficiency of the photocatalytic disinfection is largely enhanced ...

Deterring the optimum design of large-scale structures is a difficult task. Great number of design variables, largeness of the search space and controlling great number of design constraints are major preventive factors in performing optimum design of large-scale truss structures in a reasonable time. Meta-heuristic algorithms are known as one of the useful tools to d...
