abut a major concern when using it as a HTF is that it is highly reactive with water. While NaK-water heat exchangers are common in the nuclear industry [4], it is still regarded with considerable caution in the solar industry. 但主要关心,当使用它时,因为HTF是它用水是高度易反应的。 当...
From a mechanical integrity standpoint, mixing a highly reactive metal (aluminum) with a corrosive electrolyte solution is a delicate proposition; errors in electrolyte composition can result in premature failure, as evidenced by the “capacitor plague” of the early 2000’s. Another shortcoming of a...
e The hypoxic vasodilation response was not affected by the pretreatment of the vessel with L-NAME, a NOS inhibitor. f The hypoxic vasodilation response of the isolated resistance arteries was inhibited by carbon monoxide. g The dilation in response to Na2S2O4 is NO-mediated, as treatment with ...
Graphene is a two-dimensional single-atom carbon-packed material that possesses fascinating properties, including a large surface area, remarkable electrical conductivity, extraordinary intrinsic electron mobility, high Young's modulus, superior mechanical strength, optical transmittance, catalytic performance, ...
carbon via the rTCA pathway under these conditions requires specific adaptations of the genes involved as recently reported for a marine nitrite-oxidizing bacterium46. Indeed, the gene operon encoding the OOR and POR enzymes inUS. plumahas five subunits instead of the four subunits present in ...
our study represents a unique contribution to soil science based on a large, integrated dataset from a long-term field experiment, offering significant advantages compared to largely lab-based priming studies. Carbon storage in the deep soil is highly sensitive24to porewater fluxes containing fresh ...
These job orders document and track reactive maintenance. The contractor or technician can include information detailing the cause of the breakdown, the type of work performed to restore the system, and necessary measures to prevent such breakdowns from happening in the future.Related: How to Become...
Most plants split water molecules to generate energy, and now we have a clearer picture of exactly how they do it.
Nanoporous S-doped carbon and its composites with graphite oxide were tested as adsorbents of CO2 (1 MPa at 0 °C) after degassing either at 120 °C or 350 °C. The adsorption capacities were over 4 mmol/g at ambient pressure and 8 mmol/g at 0.9 MPa in spite of a low volume of ...
Titanium is a shiny gray metal with a low corrosion rate and high strength. It is a very useful metal for its refractory properties due to its high melting and boiling points. Titanium metal compounds include oxides, sulfides, alkoxides, nitrides, carbides, etc. ...
