In spite of better performance, the disposal used petroleum-based cutting fluids threatens our environment. Thus, it is essential to develop eco-friendly for performing machining operations in industries. The main contribution this paper an fluid plain turning AISI 1010 steel which automotive industry. present work, boric acid (H3BO3) was mixed with neem seed. Neem seed oil easily available man...

With the development of nuclear industry, spent fuel (SNF) generated from power plants arouses people’s attention as a result its high radioactivity, and how to guarantee reliable operation facilities staff’s safety occupies crucial position. To avoid lethal irradiation, lot functional neutron shielding composites have been developed transform fast neutrons into thermal which can be absorbed wi...

The production of nanoparticles as thin film coating performed with electrodeposition method is easier and cheaper than other methods. Because, can be controlled the change ingredients in bath composition. In this study, Co, Ni, CoNi alloy films were fabricated through composition that consists cobalt sulphate (CoSO4.7H2O), nickel (NiSO4.6H2O), (II) chloride (NiCl2 6H2O) boric acid (H3BO3). Cry...

The structure and bioactivity of a polysaccharide extracted and purified from a 4M KOH + H3BO3 solution from Prunus dulcis seed cell wall material was studied. Anion-exchange chromatography of the crude extract yielded two sugar-rich fractions: one neutral (A), the other acidic (E). These fractions contain a very similar monosaccharide composition: 5:2:1 for arabinose, uronic acids and xylose, ...

It is important to develop functional transmucosal implant surfaces that reduce the number of initially adhering bacteria and they need to be modified to improve the anti-bacterial performance. Commercially pure Ti sheets were anodized in an electrolyte containing ethylene glycol, distilled water and ammonium fluoride at room temperature to produce TiO2 nanotubes. These structures were then ann...

Boron (B) is an essential plant micronutrient which can be phytotoxic to plants when present in soils in high concentrations. However, despite its agronomic importance, B toxicity is poorly understood. In the present work, we study the response of the biosynthesis of cysteine and glutathione concentration under conditions B toxicity (500 mM H3BO3), given that this biosynthetic pathway is essent...

In this study, investigation of the combustion properties Oriental beech wood (Fagus orientalis Lipsky) impregnated with boron compound (borax (Na2B4O710H2O), boric acid (H3BO3) doped rosin (C19H29COOH) was aimed. For purpose, samples were prepared according to ASTM E 160-50 and by method medium-term dipping (24 hours) D 1413 producers’ definition. Combustion after process determined 160-50. As...

Objetivou-se com o presente estudo estabelecer uma metodologia para a conservação de grãos pólen da Carnaúba (Copernicia prunifera (Miller) H.E. More). A viabilidade dos pólen, recém-liberados, foi avaliada pelas técnicas coloração por carmim acético 1%, Reativo Alexander e lugol. taxa germinação in vitro verificada através três meios cultura: M1: 100g L-1 sacarose; 10g ágar; M2: 500mg H3BO3; M...
