Carbon Oxide refers to a group of compounds that include carbon monoxide (CO) and carbon dioxide (CO2). Carbon monoxide is harmful when exposed above 25 ppm, while carbon dioxide is less toxic. Tin dioxide nanowires have been used to sense carbon monoxide in the presence of reducing gases li...

To investigate the utilization of lignin-related aromatic compounds by the collaboration of anaerobic and aerobic bacteria, we employed the acetogen A. woodii and the strictly aerobic ADP1 for this study. ADP1 was chosen as the aerobic production chassis because of its versatile metabolism and the...
Anthropogenic land use changes (LUCs) impart intensifying impacts on soil organic carbon (SOC) turnover, leading to uncertainty concerning SOC mineralization patterns and determining whether soils act as “source” or “sink” in the global carbon budget
Light with one of those polarizations interacts in a different way with a chiral substance, which results in an inequality of left- and right-handed light absorption; this is referred to as circular dichroism (CD). Its value is defined as: CD ¼ AL À AR, with AL and AR being ...
high compression strength and modulus make it an interesting matrix material in this regard. Henkel is following a comprehensive approach and is using its benzoxazine know-how to offer the best possible solutions. As shown in the previous chapters, special monomers have been designed, synthesis metho...
and for its recreational and aesthetic value. However, its role in carbon accumulation has not been fully addressed. We assessed plant diversity, forest structure and carbon stocks in a gradient of three forest types (Natural Forest-NF; Exotic Woodland-EW and Production Forest-PF) in three of ...
In some of its aspects, the invention relates to silicone-based compositions that contain silicone based polymers and carbon nanostructures (CNSs). In some embodiments, compositions or articles contain carbon nanostructures, fragments of carbon nanostructures, fractured carbon nanotubes, elongated CNS ...
