Hydrothermal vents appear to be the tip of the subsurface biosphere in the ocean crust. The primary producers in this biosphere are prokaryotes that tolerate a wide variety of physical and chemical conditions and are versatile in their use of inorganic compounds to drive metabolism. A synthesis of...
It might therefore be expected that there would be a large number of sources of these chemicals. Although this is true for inorganic chemicals, surprisingly most organic chemicals can originate from a single source such as crude oil (petroleum)....
Plants grown with the inorganic sources of P had higher P efficiency values (dry matter produced per unit P taken up) than plants grown with organic sources of P. Phosphorus from organic compounds appeared to be more readily available to sorghum plants than P from inorganic compounds. Of the ...
Here we use field observations and air-quality modelling to quantify the major primary and secondary sources of particulate matter and of oxidative potential in Europe. We find that secondary inorganic components, crustal material and secondary biogenic organic aerosols control the mass concentration of ...
Key materials discoveries have prompted the rise of inorganic light-emitting diodes in the lighting industry. Remaining challenges are being addressed to further extend the impact of this technology in lighting, displays and other applications. Philipp Pust , Peter J. Schmidt & Wolfgang Schnick Artic...
The vaporization point of copper is high (about 2350 °C [4262 °F]), and it is rare to encounter these fumes in industry. Another hazard in copper mining is concurrent exposure to more hazardous metals and compounds. Exposure to arsenic, selenium, lead, and cadmium is associated with ...
Composts were added at 20 g kg−1 resulting in a total P addition of 4.1 mg kg−1 soil with the low P compost and 33.2 mg kg−1 soil with the high P compost. The same amount of P was added with the other amendments (residues and inorganic P). All amendments increased ...

3. Pulverized coal particles have a distribution of sizes with a mean diameter of approximately 50 μm [10]. For US coals, approximately 10% of the mass of coal as fired is present as mineral constituents and other inorganic compounds. The minerals can be present as essentially coal-free ...
of magnitude on either side of the\(\alpha\)of the chosen analytical method, those ligands will be detected, while those outside this window will not be detected accurately78. The ASV method has a very low analytical window since it only measures labile Cu complexes (inorganic Cu), and ...
