Systematic doping of pure molten KNO3 bath by sodium nitride was used to analyze the effect of salt poisoning on the mechanical performances of chemically tempered soda-lime-silicate float glass. The ion-exchange process appears partially influenced by the presence of limited amount of Na in the potassium nitride bath. The interdif‐ fusion coefficient and the penetration depth of K are invarian...

Abstract During the summer months, greenhouse tomato production is challenged by heat, causing yield reduction; therefore, we conducted a study to test effectiveness of different foliar spray compositions for improvement Lycopersicon esculentum var. cerasiforme ‘Qianxi’ nutrition uptake and fruit yield. Two forms silicon, two kinds organic nitrogenous compounds water as control factor were two-...

present for the formation mechanism. A famous •gPfeffer's semi-permeable membrane•h made of potassium ferrocyanide and copper sulfate in unglazed pottery cylinder by W. Pfeffer in 1877 is quite different from an artificial semi-permeable membrane at present, which is organized only by handling of extending high molecular substances, that is, collodium, cellophane, and various synthetic resins. ...

A linear relationship exists in oxide glasses between glass transition temperature (Tg) and quadrupole splitting ( A ) of Fe , + . DTA and Mössbauer measurements of silicate and tungstate glasses yielded large slopes of 680 and 260 °C/(mm s~ 1 ) f rom the slope of the straight lines when Fe + occupied, as network former (NWF), distorted tetrahedral Si and distorted octahedral W 6 + sites, respe...

Brown corundum dust is a solid waste produced during the preparation of brown with bauxite as raw material. The has relatively high gallium content; therefore, it great value to recover from this kind dust. In paper, range analysis and characterization methods, including XRD, XRF, SEM-EDS, EPMA, were used determine occurrence gallium. It was found that mainly present in potassium-rich phase, wr...

The efficacy of soil conditioner (vermicompost tea), fertiliser (potassium silicate), and biological control agents (BCAs) as practical agroecological copper alternatives against olive leaf spot (Spilocaea oleaginea (Cast.) Hughe.) disease was investigated between 2018 2021 under organic management in a Mediterranean climate. In total, 9 to oxychloride tea, potassium silicate, Bacillus subtilis...
