Imine-containing bridging groups were formed during self-assembly of periodic mesoporous organosilicas by in situ dynamic covalent chemistry of aldehyde and amine groups in the presence of poly(ethylene oxide)-poly(dl-lactic acid-co-glycolic acid)-poly(ethylene oxide) block copolymer in acidic aqueous solutions.
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
in this study, the morphological and chemical properties of carob pods and carob beans as well as the effect of different extraction, and purification methods on the physical and chemical properties of the purified gums have been investigated. in order to dehusk carob beans, boiling water as well as acidic methods were used. the endosperm powder was prepared and the effect of endosperm powder c...
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
Dry whey enriched with magnesium and manganese (DW) that contains protein in the amount of 13 %, a concentrate (WPC) content 65 have been chosen as functional bases production complex baking improvers targeted effect. When developing composition improver, rational dosage DW is 2 % by weight flour, WPC – 3 flour. Adding during kneading wheat flour dough predetermines decrease its gluten content,...
For Iranian fermented cheese processing and ripening, different lactic acid bacteria (LAB) that affect on the physicochemical properties and hence the organoleptic characteristics of the cheese is used. Determination of physicochemical changes of cheese, particularly, organic acids is of importance. In this study five cheese formulas with five different group of cheese starters were processed a...
Utilization of genistein as a natural inhibitor was studied alone and in combination with conventional treatments on melanosis and microbial quality of fresh L. vannamei during 10 days ice storage. Treatments were as followed: A (dipping samples in distilled water), B (dipping in 1.25 % sodium metabisulphite solution), C (dipping in 0.01 % genistein + 2% glycerol solution), D (dipping in 0.1 % ...
Lactic acid, a biologically derived compound, exists ubiquitously in nature. Its existence ranges from human being to microorganisms. Having paramount industrial significance, lactic acid should be highly pure, devoid of any contaminants. Hence, development of minimum steps of platform technologies to purify it needs urgent attention. The article proposed a novel and simple process for separati...
Whole plant sunflower and sunflower without head were ensiled in plastic containers using additives in a 2×2×2×2 factorial arrangement in a completely randomized design with three replicates. Additives were molasses, urea (at 4 and 0.5 percent wet basis respectively), and a bacterial inoculant (Agros 6gr/ton of forage as manufacture’s instruction). Compared with silages without head, ensiling s...
