There is growing interest in the rational design of electrolytes for multivalent-ion batteries by tuning the molecular-level interactions of solvate species present in the electrolytes. Herein, we report our effort to control Ca-ion speciation in ionic liquid (IL) based
Calcium is an essential cofactor for metal efflux by the …
6/8/2018· Calcium activates Fpn-mediated iron efflux We considered the hypothesis that Fpn functions as an iron/ion antiporter. Metal transport by both BbFpn and human Fpn was previously shown to be pH-sensitive, but independent of the TM H + gradient 8, 10.In
Loading a Calcium Dye into Frog Nerve Endings Through …
Summary Here, we describe a method for loading a calcium-sensitive dye through the frog nerve stump into the nerve endings. We also present a protocol for the recording and analysis of fast calcium transients in the peripheral nerve endings. Cite this Article Copy
Calcium Sulfate Market: Market Research
Calcium sulfate is also utilized as a soil conditioner in agriculture industry, as a coating agent in paper industry, as a drying agent in chemical laboratories, and as a colored pigment in paints. Increase in use of calcium sulfate in building materials such as quick setting cements, plaster of Paris, and wall plasters is the primary factor that drives the growth of the global calcium sulfate

Iron Chelators - Harvard University
Since these drugs disperse diffusely in the body, they must bind the target metal ion preferentially over others. Desferrioxamine (Desferal ® ), for instance, can be used to treat iron overload since the drug binds iron with a large preference over other metal ions such as calcium (Kd=10 -31 M for iron, Kd=10 -9 M for calcium) (1) .

1-Tetralone - Wikipedia
With calcium in liquid ammonia, 1-tetralone is reduced to 1-tetralol at -33 C in 81% yield. The methylene group in α-position to the keto group is particularly reactive and can be converted with formaldehyde (in the form of the trimeric trioxane) to 2-methylene-1-tetralone in the presence of the trifluoroacetic acid salt of N-methylaniline with yields up to 91% .

Oxalic Acid - Properties and Manufacturing of Oxalic Acid
The precipitation of calcium results in the formation of calcium sulphate dihydrate (CaSO4.2H2O). The mother liquor was then taken to a crystallizer and concentrated to the specific gravity of 300Be. Finally, Crystals of oxalic acid in the form of dehydrating was obtained which was then washed and dried.
