Deep ultraviolet and visible crystalloluminescence of sodium chloride.
A protocol has been developed for production of intense crystalloluminescence (XTL) from sodium chloride in aqueous solution by selective doping with transition metal salts (Ag(+), Cu(2+), and Dy(3+)). The method was used to record complete, fully dispersed deep UV-visible (200-650 nm) XTL spectra of sodium chloride for the first time. The results show conclusively that the emissions are due to...
متن کاملSodium chloride
Human toxicity High NaCl intake without corresponding intake of water can lead to hypernatremia: the ratio of sodium to water exceeds normal, and both the plasma sodium concentration and the total body sodium increase. Consequently, the balance of extracellular and intracellular osmolality is disturbed, which can result in several clinical symptoms, like excessive thirst, weakness, headache, ir...
متن کاملEffect of Calcium Chloride on Growth and Yield of Tomato under Sodium Chloride Stress
The effects of salinity and supplied calcium chloride on growth and leaf ions concentration of tomato (Lycopersicon esculentum L.) were investigated in Gorgan, Iran. A factorial experiment was conducted based on RCBD with four NaCl levels (0, 50, 100, and 150 mM) and four CaCl2 levels (0, 100, 200 and 300 mg L-1). Data of growth, yield and leaf’s Ca, K, and Na content were subjected to analyze ...
متن کاملSodium-potassium-chloride cotransport.
Obligatory, coupled cotransport of Na(+), K(+), and Cl(-) by cell membranes has been reported in nearly every animal cell type. This review examines the current status of our knowledge about this ion transport mechanism. Two isoforms of the Na(+)-K(+)-Cl(-) cotransporter (NKCC) protein (approximately 120-130 kDa, unglycosylated) are currently known. One isoform (NKCC2) has at least three altern...

were aged in vitro for 24 hours at 370C. Nor was the normal rate of loss of 2,3-diphosphoglycerate, ATP, or glutathione from the red cells affected by the presence of chloramphenicol over the same period. Consequently, this bacteriostatic agent can be added to blood samples taken under nonsterile conditions, such as from the heel of an infant, in order to preserve them from the effects of micro...
