Highly nitrogen doped carbon nanofibers with superior rate capability and cyclability for potassium ion batteries

open access: yesNature Communications, 2018
Potassium-ion batteries are a promising alternative to lithium-ion batteries. However, it is challenging to achieve fast charging/discharging and long cycle life with the current electrode materials because of the sluggish potassiation kinetics.

Co-Mn-Al mixed oxides promoted by K for direct NO decomposition: Effect of preparation parameters [PDF]

open access: yes, 2019
Fundamental research on direct NO decomposition is still needed for the design of a sufficiently active, stable and selective catalyst. Co-based mixed oxides promoted by alkali metals are promising catalysts for direct NO decomposition, but which ...

Potassium Metabolism [PDF]

open access: yesAnaesthesia and Intensive Care, 1977
In man, mechanisms for potassium excretion are complex and highly developed, while potassium conservation is potentially inadequate. Potassium balance is regulated by alterations in excretion in the distal renal tubule, where mineralocorticoid hormones and Na-K A T Pase are the major regulating factors.

Potassium and phosphorus transport and signaling in plants.

open access: yesJournal of Integrative Plant Biology, 2020
Nitrogen (N), potassium (K), and phosphorus (P) are essential macronutrients for plant growth and development, and their availability affects crop yield. Compared with N, the relatively low availability of K and P in soils limits crop production and thus

Potassium clavulanate [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2010
The title salt, K(+)·C(8)H(8)NO(5) (-) [systematic name: potassium (2R,5R,Z)-3-(2-hy-droxy-ethyl-idene)-7-oxo-4-oxa-1-aza-bicyclo-[3.2.0]heptane-2-carb-oxyl-ate], a widely used β-lactam anti-biotic, is usually chemically unstable even in the solid state owing to its tendency to be hydrolysed. In the crystal structure, the potassium cations are arranged

Potassium: A Vital Regulator of Plant Responses and Tolerance to Abiotic Stresses

open access: yes, 2018
Among the plant nutrients, potassium (K) is one of the vital elements required for plant growth and physiology. Potassium is not only a constituent of the plant structure but it also has a regulatory function in several biochemical processes related to ...

The conduction pathway of potassium channels is water free under physiological conditions. [PDF]

open access: yes, 2019
Ion conduction through potassium channels is a fundamental process of life. On the basis of crystallographic data, it was originally proposed that potassium ions and water molecules are transported through the selectivity filter in an alternating ...

Functioning of potassium and magnesium in photosynthesis, photosynthate translocation and photoprotection.

open access: yesPhysiologia Plantarum : An International Journal for Plant Biology, 2018
Potassium (K) and magnesium (Mg) are mineral nutrients that are required in large quantities by plants. Both elements critically contribute to the process of photosynthesis and the subsequent long-distance transport of photoassimilates. If K or Mg is not
