Molecular distillation technology has been adopted to obtain a bio-oil fraction rich in carboxylic acids and ketones. This unique bio-oil fraction was then upgraded with a La-promoted solid acid catalyst. Three washing pretreatments were used to prepare catalysts A, B, and C, with the intention of reducing the amounts of residual sulfuric acid. Model reactions were used to estimate their cataly...

Epidemic prevention policies in hospitals address issues such as, indoor air quality control, cleanliness of medical staff clothing and employee hand-washing procedures. Our hospital employed Bio-Kil to treat air-conditioning filters and nursing staff uniforms. We also assessed the efficacy of different detergents. Using Bio-Kil technology, the mean bacterial count in the air was reduced from 1...

We present a versatile method for continuous-flow, on-chip biological processing of cells, large bio-particles, and functional beads. Using an asymmetric post array in pressure-driven microfluidic flow, we can move particles of interest across multiple, independent chemical streams, enabling sequential chemical operations. With this method, we demonstrate on-chip cell treatments such as labelin...

Substitution of coal in coking blend with bio-coal is a potential way to reduce fossil CO2 emissions from iron and steelmaking. The current study aims explore possible means counteract negative influence cokemaking. Washing kaolin coating bio-coals were conducted remove or bind part the compounds ash that catalyzes gasification coke CO2. To further how increase reactivity related more reactive ...

In the search for a renewable energy source that could replace petroleum and other nonrenewable energy sources, pyrolysis of biomass is a hopeful alternative and pretreatment could further improve its potential. There are several possible routes for pretreating lignocellulosic biomass, but many need further refining before becoming economical. The main obstacle for the conversion of biomass to ...

BACKGROUND New brands of potential long lasting insecticide nets (LLINs) and LLIN treatment kits require field evaluation before they are used in a vector control programme. OBJECTIVES The aim of this study was to evaluate the bio-efficacy, usage, washing practice and physical integrity of nets treated with LLIN treatment kit, ICON MAXX in a phase III field trial in Odisha state, India. MET...

Removal of pathogenic organisms from reprocessed surgical instruments is essential to prevent iatrogenic infections. Some bacteria can make persistent biofilms on medical devices. Contamination of non-disposable equipment with prions also represents a serious risk to surgical patients. Efficient disinfection of prions from endoscopes and other instruments such as high-resolution cameras remains...

Dual Energy Harvesting Fabrics In article number 2300530, Ji-Soo Jang, Hyun-Cheol Song, and co-workers demonstrate a dual energy harvesting fabric that enables bio-physicochemical generation through the co-weaving of triboelectric generator- perspiration electric generator-based fibers. The harvests not only from human movement but also sweat to power wearable IoT devices exhibits remarkable wa...

phytoremediation is a technology that uses plants for the remediation of the contaminated soils, sediments, tailings, and groundwaters. in this work, the ability of trifoliumalexanderium for the phytoremediation of the tailings soil in the anjir-tange coal washing plant was investigated. for this purpose, trifolium sp. was cultivated in three soils consisting of the tailings dam, an agricultura...
