Abstract:
Cyclodextrin played an important role in environmental protection in recent years.Application of cyclodextrins in enviroment science upon aspects;enrichment and removal of organic pollutants and heavy metals from soil,water,and atmosphere. β-cyclodextrin (β-CD) can be linked when it was sulfonation-modified.A convenient method of photocatalytic degradation of pesticide in lab by self-designed photocatalytic equipment was proposed based on analysis and comparison of different methods used to determine pesticide. The effects of illumination,reaction time,and pesticide concentration were analyzed

Abstract:
Solder joints provide mechanical and electronic connections between solders and components for various levels in microelectronic package. However, due to different thermal expansion coefficients and elastic modulus of the associated materials, solder joints are susceptible to fatigue degration, microcracks and fracture. The solder joint reliability is, therefore, critical in the evalution of the joint quality. Recently, the employment of lead-free solder is attractive due to the environmental concern of the Pb-containing solder. Hence, the investigation on the unleaded solder joint is of pract

Abstract:
Bio-based polymers have been considered as an alternative to oil-based materials for their “carbon-neutral” environmentally degrative features. However, degradation is a complex system in which environmental factors and preparation conditions are involved, and the relationship between degradation and these factors/conditions has not yet been clarified. Moreover, an efficient system that addresses multiple degradation factors has not been developed for practical use. Thus, we constructed a decomposition degree predictive model to explore degradation factors based on analytical data and experime

Abstract:
<strong>ABSTRACT</strong> The objective of this study is to reduce the production cost of cellulase by optimizing the production medium and using an alternative carbon source such as agricultural solid waste residue. Present studies describe the optimization of process parameters for the production of cellulases by . The fermentation experiments were carried out in shake flasks. Maximum production of cellulases (0.63 U/ml) was observed after a fermentation period of 72 hrs at an temperature of 40&deg; C. Initial pH of the culture medium was also optimized and a pH of 5 was found to support max
