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.

Introduction Lithium-ion batteries are currently produced on a large scale mainly as equipment for powering portable electronic devices, but simultaneously intensive research is carried out on the development of large and high power batteries for powering hybrid electric vehicles (HEVs) and plug-in HEVs. We have reported that boric ester electrolytes showed the high oxidation potential. Boric e...

Boron (B) in soil is taken up by roots through NIP5;1, a boric acid channel, and is loaded into the xylem by BOR1, a borate exporter. Here, the function of Arabidopsis thaliana NIP6;1, the most similar gene to NIP5;1, was studied. NIP6;1 facilitates the rapid permeation of boric acid across the membrane but is completely impermeable to water. NIP6;1 transcript accumulation is elevated in respon...

Pistachio suffers from some physiological disorders such as fruit abscission, endocarp lesion, blankness, non-split, early-split and deformed nuts. In this experiment, the effects of calcium nitrate (2 gr/lit), calcium chloride (2 gr/lit), boric acid (200 ppm) and their combination treatments were investigated on physiological disorders of ‘Kaleh-Ghoochi’ pistachio. Foliar application was appli...

Boric acid (B) forms a 2:1 hydrogen-bond adduct, M·2B, with melamine (M), wherein, a finite tetrameric ribbon of boric acid forms hydrogen bonds with the nitrogen donor sites of M. Hydrogen-bonded layers of B and M in the bc-plane are connected by boric acid units along the a-axis to give a three dimensional structure. Interestingly, one of the amino groups of M does not participate in hydrogen...

It is possible to obtain pollen germination and pollen tube growth in vitro if boric acid is present. In this work the effect was studied using as a semiquantitative parameter the mean length (J) o f Lilium longißorum pollen tubes. Pollen tube growth was examinated in depend­ ence on boric acid, ortho-silicic acid, nucleic bases, Ca2+ and Zn2+ in 10% sucrose solution. The maximum o f 7is obtain...

optimal nutrition of grapevine is one of the most important factors that affect the quantity, quality and time of fruit ripening. to increase the quantity and quality of ‘askari’ cultivar, a factorial experiment in a randomized complete block design with three replications was conducted at shahrekord in 2010. treatments consisted of four levels of potassium sulfate fertilizer (zero, 300, 600 an...

Chemical oxo-preceipitation (COP) process that combined the oxidant treatment and precipitation using metal salts was developed for boron containing water disposal under relatively milder conditions (room temperature, pH 10) than a precipitation process. Among the selected boron compounds in 1000 mg-B L, including boric acid (H3BO3), metaborate (NaBO2), borax (Na2B4O7) and perborate (NaBO3), th...

Previous studies on the reproductive toxicity of boric acid have indicated that male rodents suffer testicular atrophy after treatment. There were, however, no studies of the potential effects on female fertility or on the neonate. In addition, no study described the development of the testicular lesion, thought to be related to the mechanism of toxicity. A Reproductive Assessment by Continuous...

Fabrication of a test strip for detection of benzoic acid was successfully implemented by immobilizing tyrosinase, phenol and 3-methyl-2-benzothiazolinone hydrazone (MBTH) onto filter paper using polystyrene as polymeric support. The sensing scheme was based on the decreasing intensity of the maroon colour of the test strip when introduced into benzoic acid solution. The test strip was characte...
