The influence of benzoate anions on the corrosion inhibition effect of benzotriazole (BTA) for mild steel in sulfuric acid has been investigated. The investigation was carried out by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization techniques. The addition of benzoate ions greatly enhances the inhibition efficiency of BTA in a synergistic manner. This effect has bee...

We have developed a magnetic bottle time-of-flight electron-electron coincidence spectrometer to perform measurements on solvated molecules in liquid micro-jet. present here the first results obtained after ionization of oxygen 1 s inner-shell sodium benzoate and show possibilities filter out electron signal arising from phase water gas phase. Both photoelectrons Auger electrons spectra (unfilt...

In this study, benzoate dioxygenase from Rhodococcus ruber UKMP-5M was catalyzed by oxidating the benzene ring to catechol and other derivatives. The benzoate dioxygenase (benA gene) from Rhodococcus ruber UKMP-5M was then expressed, purified, characterized, The benA gene was amplified (642 bp), and the product was cloned into a pGEM-T vector. The recombinant plasmid pGEMT-benA was digested by ...

Abstrak. Minuman sari buah kawista merupakan minuman olahan dari yang siap dikonsumsi. Penambahan natrium benzoat dan suhu penyimpanan berbeda salah satu teknik untuk mempertahankan mutu kawista. Tujuan penelitian ini adalah mengetahui pengaruh penambahan terhadap tingkat kerusakan berdasarkan uji organoleptik Rancangan Acak Lengkap (RAL) faktorial dengan 2 faktor, yaitu penyimpanan. Faktor ter...

N(G)-nitro-arginine (NNA) is known to exhibit stereoselective pharmacokinetics in which N(G)-nitro-d-arginine (d-NNA) has a faster clearance rate than N(G)-nitro-l-arginine (l-NNA) in anesthetized rats, and d-NNA undergoes unidirectional chiral inversion. It was postulated that chiral inversion of d-NNA was performed in a two-step pathway by d-amino acid oxidase (DAAO) followed by an unidentifi...
