Mutual diffusion coefficients for calcium chloride (0.100 mol dm(-3)) in aqueous solutions containing lactose at various concentrations (from 0.005 to 0.200 mol dm(-3)) have been measured at 37°C (physiological temperature), by using a conductimetric cell coupled to an automatic system to follow the diffusion. This cell uses an open-ended capillary method based on the measurement of the electri...

The mutant strain of Aspergillus niger NG-110 was evaluated for the present investigation of citric acid production. The cultural conditions optimized during the course of study were pH and K4Fe(CN)6, K2HPO4 and CaCl2 concentrations. Cane-molasses was utilized as the basal fermentation medium. The mutant NG-110 produces maximal amount of citric acid when the pH of the medium was 6. When the con...

The freshly harvested Carambola (Averrhoa Carambola L.) fruits were packed in different packaging matrials like high density polyethylene (HDPE) with a 1% and 2% ventilation with a pretreatment 2 % CaCl2 stored at ambient and also in refrigerated conditions the temperature was in the range of 18.0 to 21.0 0 C and Relative humidity of about 86 per cent. To evaluate the storage condition and pret...

The volatilization of zinc in the electric arc furnace dust–CaCl2 and ZnFe2O4–ZnO–CaCl2–C reaction systems was investigated. Experiments were conducted under an N2 atmosphere infrared lamp heating furnace, activation energy rate determined by Ozawa method. system 123 ± 27 kJ/mol; when dust decarburized, reduced to 84 4 kJ/mol. Further, simultaneous carbothermic reduction carbon contained chlori...

The stepwise chromatographic behaviour on DEAE-Sepharose of rat Fe65, a neuronal protein, was tested, using as eluants KCl, CaCl2, and MgCl2. Assays by western blot showed that Fe65 was eluted by CaCl2, at a ionic strength 20% lower than that of MgCl2 or KCl. Interestingly, in the case of a truncated Fe65, lacking a glutamic acid rich region at the N-terminus, the ionic strengths of the various...

Sorption-based thermal storage has drawn considerable attention for sustainable and cost-effective management energy storage. However, the low sorption capacity of sorbents is a long-standing challenge achieving high-energy-density sorption-based Herein, we demonstrate an ultrahigh-energy/power-density battery (STB) enabled by graphene aerogel (GA)-based composite efficient harvesting with reco...
