The manufacture and application of aluminium phosphide fumigants pose risks of inhalation exposure to phosphine gas. This article presents a case report of suspected inhalation exposure to phosphine gas in a manufacturing facility for aluminium phosphide fumigants, which was associated with acute dyspnoea, hypotension, bradycardia and other signs of intoxication. These symptoms resolved within ...

Through the millennia wood stoves for cooking have been notoriously inefficient and slow. Electricity, gas or liquid fuels are preferred for cooking when they can be obtained. In the last few decades a number of improvements have been made in woodstoves, but still the improved wood stoves are difficult to control and manufacture and are often not accepted by the cook. Gasification of wood (or o...

Using absorption refrigeration cycles instead of vapor compression refrigeration cycles can drastically decrease energy consumption. In these systems, high level of energy consumption is reduced due to the partially elimination of vapor compression refrigeration systems. On the other hand, utilization of waste heat of the plant, which is a very good opportunity for energy saving,  is possible. ...

Costs for biotechnological processes in general are largely dictated by substrate prices. Thus, especially production of bulk chemicals from sugar or molasses suffers economically, if these compounds increase in price. A fairly recent solution to deal with this problem is the use of cheap gases as a carbon and energy source. Both, aerobic and anaerobic gas fermentations have meanwhile reached c...

High methane storage capacity in porous materials is important for the design and manufacture of vehicles powered by natural gas. Here, we report the synthesis, crystal structures and methane adsorption properties of five new zinc metal-organic frameworks (MOFs), MOF-905, MOF-905-Me2, MOF-905-Naph, MOF-905-NO2, and MOF-950. All these MOFs consist of the Zn4O(-CO2)6 secondary building units (SBU...

Whilst columnar zinc oxide (ZnO) structures in the form of rods or wires have been synthesized previously by different liquid- or vapor-phase routes, their high cost production and/or incompatibility with microfabrication technologies, due to the use of pre-deposited catalyst-seeds and/or high processing temperatures exceeding 900 °C, represent a drawback for a widespread use of these methods. ...

The updated Nanostructure materials and nano technological tools are predicted to enable the synthesis of novel polymers, as well as polymer–inorganic composites to manufacture higher qualified membranes possess attractive physical and chemical properties with high performed sensitivity and selectivity. An accurate and simple method for drug analysis is required for forensic toxicological inves...
