The effects that an increase of environmental pH has on the triple helix of scleroglucan (Sclg) and on the Sclg/borax hydrogel are reported. Rheological experiments show that the hydrogel is less sensitive to pH increase than Sclg alone, while at pH = 14 a dramatic viscosity decrease takes place for both systems. This effect is evidenced also by the reduced water uptake and anisotropic elongati...

Effects of heat-transferring property of silver nanoparticles were evaluated on two solid woods of poplar and fir and in combination with Borax. Nanosilver and Borax were applied in pressure vessel using Rueping method. The size range of silver nanoparticles was 20-80 nm. Specimens of 150×130×9 mm were prepared and five fire-retarding properties were measured using a newly designed slide fire t...

We probe the drainage and imbibition dynamics of foams in which the continuous aqueous phase is a transient gel-like network. To produce these foams, we provide a new method - a PVA (polyvinyl alcohol) solution is first foamed and then a cross-linker, Borax, is added, which binds reversibly to the PVA chains. The resulting foams are ultra-stable-over a month. We find that the typical time for g...

A historical perspective and description of recent studies on the use of borax to treat pine stumps against infection by Heterobasidion annosum in eastside pine stands of northeastern California are presented. The studies indicate that boraxing of pines in eastside pine stands is an effective means of preventing annosus infection. Data and observations suggest that the lower stump diameter limi...

During investigations of the specific rotation of gums, Jennings6 found that the addition of 20 ml. 5 per cent borax solution depressed the pol of pure sucrose by more than 2 per cent. Since other investigators had found similar discrepancies with the original experimental results of Hernandez it was decided that the whole question of using borax to obtain close approximations of sucrose conten...

The Kırka borate deposit (Miocene), in western Turkey, the most important B2O3 producer at present in the world, exhibits a symmetrical zonation in a lateral sense; it is comprised of: a central body of Na borate (borax), an intermediate zone of Na–Ca borate (ulexite), and a marginal zone of Ca borate (colemanite). This mineral zonation is also developed in a vertical sense, although it is some...

During the course of current investigations on the effect of minor elements on the nutrition of flax it has been observed that applications of boron, as sodium tetraborate, to field plots have essentially prevented the development of rust (Melampsora lini) on Bison and Redwing flax. The borax was applied in solution at the rate of sixty pounds to the acre, on May 23, two weeks after germination...
