Contaminant control is becoming a major issue of nanoscale device. Cryogenic aerosol beam using micron-sized aerosol particles has long been successfully used to remove contaminant particles (CPs) down to 50nm, and supersonic particle beam using particles smaller than 100nm lowered the limit of cleaning down to 20nm size. In this study, the supersonic particle beam technique that uses nanometer...

This study contributes to the improvement of low-cost biotechnology for wastewater treatment in constructed wetlands (CWs). Constructed wetlands are energy efficient engineered systems that mimic the treatment processes of natural wetlands, removing polluting organic matter, nutrients, and pathogens from water. The aim of this study was to investigate the advisability of the inoculation of hori...

Abstract We describe a method for cleaning leaf epicuticular wax and contaminants from herbarium specimens in preparation scanning electron microscopy. Specimens are rinsed chloroform, heated at 50°C 8 hrs, ultrasonicated 70% ethanol, subjected to critical-point drying. This helps preserve reveal the surface details of that heavily covered with contaminants, making many morphologically function...

Renewable energy, water conservation, and environmental protection are the most important challenges today. Osmotic membrane bioreactor (OMBR) is an innovative process showing superior performance in bioenergy production, eliminating contaminants, low fouling tendency. However, salinity build-up main drawback of this process. Identifying microbial community can improve production contaminant tr...
