Background and Objective: Microbial fuel cell (MFC) is a new green technology that uses the catabolic ability of microorganisms to produce bioenergy while simultaneously removing organic matter and other wastewater contaminants. Electrode material is one of the factors affecting the performance of microbial fuel cells. The aim of this study was to investigate the performance of microbial fuel c...
توزیع اندازه منافذ (psd) برای استفاده، طراحی و بهبود سیستم های متخلخل در برنامه های مختلفی از جمله مطالعه کاتالیست های نا همگن، انتقال جرم در مواد متخلخل، فرایندهای جداسازی، حذف آلاینده های مختلف، ذخیره سازی گاز و جذب فیزیکی بکار برده می شود. psd نقش تعیین کننده ایی در رفتار جذب مواد متخلخل از جمله جاذب های کربنی نانو ساختار مانند کربن فعال و کربن نانو لوله، دارد. مدل های ریاضی متفاوتی برای تعی...
background and objectives: active coal is applied in tissue culture media as the absorbant of phenolic compounds and toxic materials; but no research has been done regarding its direct application like spray on plants. application of this material as the carbone source is based on researches done by sucrose; which had highly positive effect on plant growth and development. thus; a hypothesis wa...
Influence of Natural Sources of Biologically Active Substances on Livestock and Poultry Reproduction
Synthetic hormones and bioactive substances (vitamins, pigments and isoflavons) which have been used in the feed industry are accumulated in milk, meat and eggs. It is suspected that these are responsible for a number of side-effects such as carcinogenesis, liver and kidney damage, allergies in consumers. Furthermore the synthetic hormones, vitamins, pigments are less active than those extracte...
Nonprecious carbon catalysts and electrodes are vital components in energy conversion and storage systems. Despite recent progress, controllable synthesis of carbon functional materials is still a great challenge. We report a novel strategy to prepare simultaneously Fe-N-C catalysts and Fe3O4/N-doped carbon hybrids based on the sol-gel chemistry of gelatin and iron with controllability of struc...
the aim of this study is to verify the amount of nitrate absorption on latium composite over active carbon in which ph parameters, temperature, pollutant concentration, contact time for absorbent were considered. it was determined that optimum condition for absorbent are ph=3, t= 0 ˚c and initial concentration of solution=10 ppm, then absorption parameters verified and after drawing absorption...
