Potassium (K) is a primary macronutrient for overall plant growth, yield potential, product quality and stress resistance of crops. Potato (Solanum tuberosum L.) crops require high amount potassium to achieve the ideal quality. Therefore, determination optimum K rate efficient source potato necessary because affects crop physiological processes, dry matter production, cooking, processing requir...

A supercapacitor is an energy-storage device able to store and release energy at fast rates with extended cycle life; thus, it used in various electrical appliances. Carbon materials prepared above 800 °C of activation temperatures are generally employed as electrode material for supercapacitors. Herein, we report carbon from a low-cost petroleum waste precursor that was activated using KOH, Mg...

Potassium Nitrate has been used as a desensitizing agent to treat dentinal hypersensitivity. The effectiveness of a potassium nitrate is evaluated both in the form of a toothpaste and a mouthwash in a clinical study. Thirty patients were assessed using evaporative stimuli and thermal stimuli and response was evaluated using Visual Analogue Scale at baseline, at 2 weeks and 4 weeks. The patients...

Hydration of a commercial hydrophilic polyacrylamide gel in 20 meq Ca(NO 3)2/ liter was reduced to <10% of the maximum hydration in deionized water. Repeated soaking with deionized water to remove soluble salts restored hydration to ≈ 30% of maximum. Incorporating KNO3 at concentrations ranging from 5 to 40 meq·liter -1 with the Ca(NO3)2 in the hydration solution partially reversed the Ca 2+ in...

Oxidative precipitation is a facile synthesis method to obtain ferromagnetic iron oxide nanoparticles from ferrous salts—with unexplored potential. The concentration of base and oxidant alone strongly affects the particle's structure thus their magnetic properties despite same material, magnetite (Fe3O4), obtained when precipitated with potassium hydroxide (KOH) sulfate (FeSO4) treated nitrate ...

background and aims . the aim of this study was to evaluate the clinical desensitizing effects of potassium nitrate and strontium acetate in reduction of hypersensitivity. materials and methods . thirty eight patients who presented dental hypersensitivity were selected and randomly allo-cated into two groups. group i: patients who were treated by potassium nitrate 5% foam, and group ii: patient...
