Soil contamination is a major threat to the sustainability of agricultural fields and safety food production. This paper presented remediation techniques, including surface covering, encapsulation, thermal restoration, stabilization, solidification, phytoremediation, bioremediation, combined remediation. Bioremediation, which uses microorganisms break down contaminants, has gained popularity du...
Patent claims determining the legal protection extent of an invention play an essential role in patent rights. Type and drafting of patent claims constitute indeed the important elements for determining legal protection extent of an invention on the one hand and enforcing patenee's exclusive right against competitors on the other hand. While different drafting or interpreting methods of pate...
Ethylbenzene (EB) dehydrogenation to styrene (SM) on an industrial scale is generally performed using classic and SMART (Styrene Monomer Advanced Reheat Technology) technologies. In the current study, spent catalysts structural changes through classic and SMART technologies were investigated and compared with the fresh catalyst. For this purpose, XRF, XRD, SEM-EDX, FT-IR, BET and crushing s...
This paper aims to assess the environmental efficiency of refineries in the public sector with emphasis on generated effluents and water consumption in the production process. In order to conduct this research, the addressed method was quantitative with a qualitative approach to the environmental aspects of controllable and uncontrollable variables imp...
Generally, tantalum capacitor failure modes have been discussed both for the standard manganese dioxide cathode and the new conductive polymer (CP) type. For standard tantalum in the normal operation mode, an electrical breakdown can be stimulated by an increase of the electrical conductance in channel by an electrical pulse or voltage level. This leads to capacitor destruction followed by ther...
