The electrical properties of self-assembled monolayers (SAMs) of organic molecules on metal surfaces have gained particular interest due to their potential applications in nanometer-scaled electronics systems [1]. Understanding the transport mechanism through these thin molecular films as well as the dependence of the conductivity on the molecular length and structure, the applied load and the ...

This study assessed the removal efficiency of organic matter and how it relates to the decrease of toxic and mutagenic effects when an anaerobic reactor is used to treat the bleaching effluent from two kraft pulp mills. Parameters such as COD (chemical oxygen demand), DOC (dissolved organic carbon), AOX (adsorbable organic halogen), ASL (acid soluble lignin), color, chlorides, total phenols and...

The overall objective of this research project was to conduct an extensive study of the behavior and use of glass fiber-reinforced polymer (GFRP) and carbon FRP (CFRP) materials for bridge construction. In particular, GFRP honeycomb sandwich panels were used as bridge panels and steel-supported bridge deck panels and CFRP and GFRP bars were used as internal reinforcement for precast concrete br...

Since the 1980s, advances in wastewater treatment technology have led to considerably improved surface water quality in the urban areas of many high income countries. However, trace concentrations of organic wastewater-associated contaminants may still pose a key environmental hazard impairing the ecological quality of surface waters. To identify key impact factors, we analyzed the effects of a...

the cane alcohol vinasse assessment on the removal efficiency of a fixed biomass anaerobic reactor (fbar) was evaluated. crude vinasse was used to feed the reactor. the fbar was operated with organic load rate (olr) of 0.5, 1, 3 and 6 gcod/l/d. removal efficiencies of 85, 82, 75 and 66 per cent were observed respectively. the fba reactor presented an excellent removal of organic matter, however...

Pumped Thermal Energy Storages (PTES) are suitable for bridging temporary energy shortages, which may occur due to the utilization of renewable sources. A combined heat pump (HP)-Organic Rankine Cycle (ORC) system with thermal storage offers a favorable way store small medium sized applications. To address aspect flexibility, part load behavior HP-ORC system, both having R1233zd(E) (Trans-1-chl...

Development of materials with an antimicrobial activity is fundamental for different sectors, including medicine and health care, water and air treatment, and food packaging. Electrospinning is a versatile and economic technique that allows the incorporation of different natural, industrial, and clinical agents into a wide variety of polymers and blends in the form of micro/nanofibers. Furtherm...
