Reductions by Cobalt-Catalyzed Production of Hydrogen Gas from NaBH4 in a Two-Chamber System
… a bench-scale methodology involving a <em>two-chamber system </em>for conducting catalytic hydrogenation reactions by obtaining hydrogen (H<sub>2</sub>) gas from stable sodium borohydride (NaBH<sub>4</sub>). Whereas NaBH<sub>4</sub> is widely used for a variety of reductions and is known to …

Treatment of azo dyes in industrial wastewater using microbial fuel cells
… with concomitant bioelectricity generation in two-chamber MFCs. Power densities up-to 37 mWm-2 were observed in the two-chamber MFC system during AO-7 decolourisation. Co-metabolic reductive degradation of azo dye mixtures using dye acclimated mixed microbial populations under industrially …

Architectures for individual and stacked micro single chamber solid oxide fuel cells
… catalysis. Conventional SOFCs are designed in a two-chamber system, separating the fuel and oxidant flow to the anode and cathode, respectively. However, fuel cell manufacturing cost and robustness have proven to be the main challenges to rapid commercialization. A promising alternate method to …

Sustainable electro-bioremediation of multi-contaminated groundwater
… Initially, nitrate removal was evaluated in a two-chamber BES, focusing on the influence of hydraulic retention time on denitrification performance. Advanced cathode materials were further evaluated using carbon nanotube (CNT)-based membranes for denitrification. Subsequently, a three-chamber …

THE EFFECT OF NALTREXONE ON NICOTINE-INDUCED CONDITIONED PLACE PREFERENCE IN RATS
… and alcohol addiction in humans. Using standard two-chamber shuttleboxes, we first sought to establish a place preference for nicotine in rats, and once this was achieved, we sought to block nicotine place preference with naltrexone. In the first experiment, subjects did not show a place …

A microfabricated solid oxide fuel cell
… to investigate the design of one such device, a two-chamber microfabricated solid oxide fuel cell (SOFC). This device produces electric current through the electrochemical oxidation of fuel through an ionic conductor. Oxide ions permeate across a ceramic electrolyte membrane to react with the …

Endangered species : the harpsichord and its new repertoire since 1960
… from the perspective of the harpsichordist, the two types of harpsichord prominent in the musical mainstream in the twentieth century, and specific pieces written for both between 1960 and 1990. The two types of instrument under discussion are (1) the modern pedal harpsichord modelled after the …

Quintet for two violins, viola, cello and piano, and string quartet no. 1 by Lazar Nikolov
… Nikolov felt that the masters from the previous two generations had already used all the successful means to incorporate neo-Romantic features and Bulgarian folk material into art music. He was perceptive enough to recognize the danger of his generation's music sounding like mere imitation of …

Methane Emissions from Direct-Seeded, Delayed-Flood Rice Grown on a Clay Soil
… emissions from a clay soil, 2) the effect of chamber size (i.e., 15.2-cm and 30-cm inner diameter) on measurements of CH4 fluxes and emissions, and 3) the impact of previous crop [rice or soybean (Glycine max L.)] and cultivar (Cheniere, Taggart, and CLXL745) on CH4 fluxes and emissions. Total …

Seals and fisheries: a study of the conflict and some possible solutions
… as the prevention of accidental by-catch are two sides of the same problem; a solution to one is also a solution to the other. However, development of new fishing gear is challenging and time-consuming. It requires better knowledge of both fish and seal behaviour. At present suitable …

The Role of Platelets In Ovarian Carcinoma
… were evaluated using BrdU-PI flow cytometric and two-chamber chemotaxis assays. In vivo effects of platelet depletion on tumor growth, proliferation, apoptosis, and angiogenesis were examined using an anti-platelet antibody (anti-mouse glycoprotein 1ba, Emfret) to reduce platelets by 50%. Complete …

Development and Application of a Microfluidic Cultivation Platform for the Analysis and Control of Industrially Relevant Synthetic Microbial Co-Cultures
… since the analysis of the interaction between two or more different microbial organisms in co-culture is highly challenging due to the complex dynamics on different temporal and spatial scales, there are only few tools and methods available that allow accurate analysis of these interactions.<br …
