  2. High-temperature superconductivity - Wikipedia

    en.wikipedia.org/wiki/High-temperature...

    The superconducting transition temperature has been found to peak at an optimal doping value (p =0.16) and an optimal number of layers in each superconducting block, typically n =3. Possible mechanisms for superconductivity in the cuprates continue to be the subject of considerable debate and further research.

  3. Photocatalytic water splitting - Wikipedia

    en.wikipedia.org/wiki/Photocatalytic_water_splitting

    The effiency is due to the synergistic effects of promoting hydrogen–oxygen evolution and inhibiting recombination by operating at an optimal reaction temperature (~70 degrees C), powered by harvesting previously wasted infrared light. An STH efficiency of about 7% was realized from tap water and seawater and efficiency of 6.2% in a larger ...

    How do animals obtain water in the winter when water sources are frozen. Some hibernate; that's all I know. Melchoir 01:09, 1 May 2006 (UTC) []. Although this is a very silly question for us Canadians, I actually found a quote: "Studies in Canada have shown some cows have gone 50 to 60 days with snow as the sole water source without any adverse effects.

    With no potassium intake, it is excreted at about 200 mg per day until, in about a week, potassium in the serum declines to a mildly deficient level of 3.0–3.5 mmol/L. [107] If potassium is still withheld, the concentration continues to fall until a severe deficiency causes eventual death.
