The magnetic phase diagram in a single crystal of copper metaborate CuB2O4 in a magnetic field parallel to a tetragonal axis c has been investigated. From the resonant, magnetic and magnetostrictive data the phase diagram of CuB2O4 on a plane “temperature magnetic field” is constructed. The magnetic incommensuratecommensurate phase transition is caused by the saturation of weak subsystem of cop...

This document reviews the environmental fate of diuron. The chemical (IUPAC) name for diuron is N-(3, 4-dichlorophenyl)-N, N-dimethylurea (C9H10Cl2N2O). In California, registered products containing the active ingredient diuron include Direx, Karmex, and Krovar (in combination with bromacil), among others. Diuron is often used in combination with other herbicides such as bromacil, hexazinone, p...

The recycling of sodium borohydride poses a huge challenge to the drive towards hydrogen economy. Currently, mechano-chemical, thermo-chemical and electrochemical are only reported methods metaborate into borohydride. Much attention has been devoted mechano-chemical reduction, but little focus methods. This review describes behaviour (BH4−) (BO2−) anions in alkaline solutions. BH4− is stabilize...

Gaseous beryllium metaborate, Be(B02)2,has been identified mass spectrometrically in the vapor above the beryllium-boron-oxygen system. A st-jdy of this system by differential thermal analysis» and Knudsen effusion using a vacuum balance and mass spectrometer, showt-i solid DeoBo0, to be the only condensed mixed oxide phase present with a melting point of 1495 ± 5C. The following thermodynamic ...

Boric acid and its less-known derivative lithium metaborate are inorganic acids used in a wide diverse array of industrial clinical applications. In particular, boric is accepted as natural antimicrobial agent due to activity on many different microbial species. We have examined the possible dependency metaborate-induced yeast toxicity deletion antioxidative CTT1, TRR2 GSH2 genes expressions ce...

We have investigated the spin-wave spectrum of copper metaborate, CuB 2 O 4 , by means of inelastic neutron scattering in the commensurate magnetic phase. We have found two branches of spin-wave excitations associated with the two magnetic sublattices Cu(A) and Cu(B), respectively. In the temperature regime 10K ≤ T ≤ 21K, where only the Cu(A) magnetic moments are ordered, the interaction betwee...

Expressions for dichroic signals in terms of electron multipoles have been used to analyse optical data gathered on a crystal of copper metaborate in the presence of a magnetic field. Calculated signals comply with the established crystal and magnetic structures of CuB(2)O(4), and respect the global symmetries of parity-even and parity-odd dichroic signals in full. We have success in describing...
