quebracho tannin wood adhesive in non formaldehyde approach has low autocondensation rate and needs more press time than formaldehyde-based wood adhesives to produce wood composites. in this study, boric acid was used to increase autocondensation rate of quebracho tannin adhesive to make poplar plywood. the main ingredients of the adhesives include quebracho tannin, naoh, hexamine, boric acid a...
Nanosilver of nanometer-sized silver (Ag+) particles (2-5 nm diam) are used in various applications as an anti-microbial. Boric acid (H3BO3) is water soluble (pH=7). Boric acid is ethylene synthese inhibitor and reduce ethylene production through reducing the ACC synthase and ACC oxidase delays senescence of flower. In this study of different concentrations of boric acid and nano-silver was eva...
In the crystal structure of the ammonium carboxyl-ate-boric acid cocrystal, (C(3)H(7))(4)N(+)·CH(3)CO(2) (-)·H(3)BO(3), the boric acid forms two O-H⋯O hydrogen bonds to the acetate anion. The acetate-boric acid species is hydrogen bonded to another acetate-boric acid species through the third OH unit of the boric acid about a twofold rotation axis.
BACKGROUND & OBJECTIVES The use of low concentrations of boric acid as a potential and effective control agent for the eggs and immature stages of Aedes aegypti L. and Aedes albopictus Skuse (Diptera: Culicidae) is found to be safe and effective as compared to synthetic chemical insecticides. The study aims to determine the ovicidal concentration of boric acid, its effective concentration for o...
BACKGROUND Boric acid is a commonly cited treatment for recurrent and resistant yeast vaginitis, but data about the extent and mechanism of its antifungal activity are lacking. OBJECTIVES The aim of this study was to use in vitro methods to understand the spectrum and mechanism of boric acid as a potential treatment for vaginal infection. METHODS Yeast and bacterial isolates were tested by ...
Adding catalysts such as boric acid into biomass is a flexible method to achieve high biochar yield with low carbon emission levels. This work is directed towards investigating the effects of boric acid content on biochar yield, composition, and property through a two-step pyrolysis of rice husk. The results showed that biochar yields, compositions, and properties were associated with the amoun...
Micronutriens deficiency is prevalent in case of drought stress conditions, so complementary boron and zinc nutrition are important for crops to overcome drought stress. This study evaluated the effect of zinc and boron foliar application on physiological traits of sesame under different irrigation levels. The experiment was conducted as a split plot in a randomized complete block design with t...

the objective of the present study is to investigate the impact of spraying boric acid on vegetative and reproductive growth of ‘camarosa’ strawberry (fragaria × ananassa duch.). the strawberry plants were sprayed with boric acid at 0 (control), 50 and 100 mg l-1 at 30 days after planting. in general, results indicated that spraying plants with boric acid had a significant effect on yield, frui...
STRUCTURE AND DERIVATION oric acid, also called boracic acid or orthoboric acid, is an inorganic acid with the chemical formula H3BO3. It is available as a white, odorless powder and in crystalline and granular forms. Bo-ric acid vaginal suppositories are not commercially available and, therefore, must be compounded. Most studies documenting efficacy utilize 600 mg of boric acid powder in a gel...
