Solid potassium-conducting electrolytes in the ferric oxide-silica- potassium oxide and ferric oxide-germanium dioxide-potassium oxide systemBurmakin, E IShekhtman, G Sh
Crude oil is co-produced with water during the water flooding processes which contains dissolved salts of sodium, potassium, calcium, and magnesium, particularly in the case of LSWF. In this regard, systematic investigation of asphaltene-brine interactions is of interest to build fundamental understan...
Bromine, chlorine and iodine are dissolved in water to make aqueous solutions. Potassium iodide is added to each of these solutions. The following observations are made: ||halogen||initial color of solution||final color of solut...
The mixtures of sulfuric and hydrochloric acids are used, or sodium, potassium, magnesium, or calcium chloride is added to the acid solutions. The resulting precipitate of GeO2 is subjected to back extraction with water [27]. Various methods are used to determine the concentrations of trace ...
First, 0.438 g titanium potassium oxalate was added to 3 ml deionized water with ultrasonic treatment for 10 min. Then, 37 ml diethylene glycol was added and continuously stirred 15 min. Before the growth process, the FTO substrate (square resistance ≤ 6 Ω) was cleaned for 30 min in ...
Necessary diversification of battery chemistry and related cell design call for investigation of more exotic materials and configurations, such as solid-state potassium batteries. In the core of their development lies the necessity of discovering new and
The present work demonstrates an easy preparation of potassium ion impregnated calcium oxide in nano crystalline form (supported by powder X-ray diffraction and transmission electron microscopic studies) and its application as a solid catalyst for the transesterification of waste cottonseed oil with ...
An exception are sulfur-rich fuels (e.g. pet-coke), where limestone is added to the bed material, in order to reduce SO2 emissions. The combustion air is injected using jets from below and depending on gas velocity, particle size and density of the bed material, bed material is entrained...
Fenretinide is a synthetic retinoid characterized by anticancer activity in preclinical models and favorable toxicological profile, but also by a low bioavailability that hindered its clinical efficacy in former clinical trials. We developed a new formul
Deionized water (DIW) was used in all experiments. Synthesis of BiOI/CF Firstly, Bi(NO3)3·5H2O (0.97 g) and KI (3.32 g) were added into 50 mL of DIW, which was stirred to obtain the solution A. The pH value of A was adjusted to 1.7 using nitric acid. Simultaneously,...
