Nanostructured thin films of Ba-doped indium oxide have been examined for monitoring ppm levels of NOx in ambient air, and their response patterns have been recorded at different operating conditions. These films are found to be capable of sensing down to 0.5 ppm NOx concentration in air. The optimum operating temperature for sensing is found to be 300°C. Response and retrace times are typically 60 s and 300 s respectively. They are highly selective to NOx and do not show significant response to hydrogen and petroleum gas up to 5000 ppm.
A new study published in the Soil Science Society of America Journal investigated the field performance of 5 soil moisture instruments in heavy clay soils.
The HydraProbe outperformed TDR and capacitance-based soil sensors in terms of stability and accuracy in Manitoba’s agricultural soil. Much of soil in the Canadian Prairie farmland is vertisolic.

A natural gas bottleneck in the Permian Basin could force oil producers to shut wells or seek waivers to flare large amounts of natural gas if takeaway capacity does not catch up by the end of this year.

Safe operation of a Water Treatment Plant (WTP) requires careful monitoring of the water supply influent to the plant, as a guard for any substances entering the treatment works that could negatively impact treated water quality in the distribution system. One aspect of water quality that has recently garnered more attention from authorities and utilities is Natural Organic Matter (NOM), which refers to a group of carbon-based compounds found in natural water systems formed by the decomposition of organic materials...
Scientists in South East Asia have been measuring greenhouse gas (GHG) emissions from goats and cattle in a series of research projects investigating the effects of different feeding regimes. In each case, the eructed, or belched, emissions from each animal were measured with a portable FTIR gas analyzer from Gasmet Technologies. The research papers have been published by ‘Livestock Research for Rural Development,’ a peer-reviewed international journal for research into sustainable developing world...
