The determinants of effective defluorination by the LiAl-LDHs

Millions of people in poor areas are still under the threat of fluoride contamination.How to effectively separate fluorine in water is an important step to reduce the ecological risk.In this paper,we performed a systematic DFT calculation focused on the defluorination behavior between the LiAl-and MgAl-LDHs.The results indicated that the LiAl-LDHs exhibited high chemical activity before the defluorination,because of the better electronic structure.After the defluorination,the LiAl-LDHs with adso...     

An Experimental Study of Heat Pipe Performance Using Nanofluids

Heat pipe cooling is widely used in computer processors. Advances in microprocessor technology have resulted in reduced heat transfer surface area. Maintaining an efficient cooling process is therefore challenging. The main goal of this experimental study is to perform a parametric study on heat pipe performance using nanofluids. Nanofluids of 1 and 3 vol% of alumina nanoparticles of 20–50 nm diameters in deionized water versus deionized water as a base fluid were considered in the present study. The nanofluids are prepared in our laboratory using two-step method. The nanofluids thermal properties are measured to confirm the properties enhancement that could indicate a corresponding performance enhancement of the heat pipe. A 10 mm inner diameter, 200 mm long brass tube with 50 mm long evaporator, and 50 mm long water cooled condenser were used. Heat pipe wall temperature is reduced with nanofluids as is the temperature difference between the evaporator and condenser. The thermal diffusivity of the nanofluids is increased by 10%. The pipe pressure in case of deionized water was higher than the corresponding one for the nanofluids by 20–32%.

重金属污染水体的高效环保处理技术及研究进展

重金属污染作为影响环境的严重问题之一,不仅因其毒性大、易积累,而且处理后难以回收,对于重金属污染水体的处理技术,大部分仍存在成本高,易造成二次污染等问题。本文综述目前在处理工业废水中重金属离子的多种工艺技术,从环境保护、经济效益角度分析碳黑泥、矿物材料、树脂等的优缺点,提出发展高效环保型的处理技术,包括天然处理剂的应用,如竹炭,壳聚糖,微生物等,为去除重金属、净化水质提供新思路。
