A blue reflective photonic polymer coating which can be patterned in full color, from blue to red, by printing with an aqueous calcium nitrate solution has been fabricated. Color change in the cholesteric liquid-crystalline polymer network over the entire visible spectrum is obtained by the use of nonreactive mesogen. The pattern in the coating is hidden in the blue color dry state and appears ...

Microbially induced calcium carbonate precipitation is one of the biomineralization types closely dependent on the parameters of the microenvironment. Minerals are precipitated as a product of environmental and bacterial cell interactions, however, this system has very little control via microorganisms. The aim of research was to determine the influence of abiotic factors (pH, temperature, agit...

Calcium is the third most crucial nutrient for andean blackberry; however, its absorption limited in acid soils, and low mobility plant decreases effects on fruits. Therefore, effect of foliar fertilizers with calcium blackberry fruits was estimated. In three locations, experiments were established five sources (Ca chelate, CaB nitrate, Ca oxide, CaBZn gluconate) a control without calcium, appl...

Roots are subjected to a range of abiotic stresses as they forage for water and nutrients. Cytosolic free calcium is a common second messenger in the signaling of abiotic stress. In addition, roots take up calcium both as a nutrient and to stimulate exocytosis in growth. For calcium to fulfill its multiple roles must require strict spatio-temporal regulation of its uptake and efflux across the ...

groundwater contamination is a serious problem facing the countries. because groundwater is vulnerable to contamination from a variety of sources, and, once contaminated, it is very difficult to restore to its original quality. the main objective of this study was evaluation of groundwater quality in shahrekord aquifer and finding the source of the groundwater contamination. some of the chemica...

in order to study the effect of different levels of nitrogen and copper on yield and nutrients concentrations and nitrate in broccoli head, an experiment was conducted based on a factorial combinations of five levels of nitrogen (0, 100, 200, 300 and 400 kg/ha) and three levels of copper (0, 2.5 and 5 kg/ha) that were applied to soil as ammonium sulfate and copper sulfate respectively, in three...
