Selective oxidation is still a challenge for targeted conversion of biomass derived substance to high-value added products. Herein we report an efficient electrochemical strategy transform phenol into p-benzoquinone, by tandem oxidations CuSO4 and CoSO4 catalysts in electrolyte. Co3+ generated at the anode from Co2+ diffuses solution reacts with form hydroquinone, which subsequently oxidized Cu...

A ligand exchange HPLC method for enantioseparation of ofloxacin enantiomers was developed by a using C8 stationary phase. Chromatographic separation was performed on a Zorbax-300SB-C8 column eluted with the mobile phase consisting of 15 % methanol in water containing 10mM phenylalanin and 5 mM CuSO4 at flow rate of 0.8 mL/min. The method was simple, rapid and suitable for routine analytical st...

In this work the physiological effect of copper excess on the peach rootstock MrS 2/5 and GF 677 was studied by means of an in vitro system. Two different copper treatments (10 and 100 μM CuSO4) for each rootstock were carried out and compared to a control containing 0.1 μM of CuSO4. Relative growth rate and copper concentration inside rootstock tissues were measured after 21 days from the begi...

Groundwater is an indispensable resource for humankind and sustainable biomes functioning. Anthropogenic disturbance threatens groundwater ecosystems globally, but to which extent organisms respond stressors remains poorly understood. animals are rare, with small populations, difficult find breed in the lab, poses a main challenge assessment of their responses pollutants. Despite difficulties, ...

Copper-ion conducting gel polymer electrolyte (GPE) systems based on poly(vinyl alcohol) (PVA) and copper sulphate salt doped with glycerin as plasticizer have been synthesized by using solution casting technique. Differential scanning calorimetry (DSC) is used to examine the thermal effect of a electrolyte. With addition various quantities glycerin, in pure PVA + 20 wt% CuSO4 shows decrease va...

Organik bir malzeme olan odun, odun tahripçisi organizmalar tarafından bozundurulmakta ve tahrip edilebilmektedir. Bu amaçla geçmişten günümüze kadar birçok emprenye maddesi geliştirilmiş halen de geliştirilmeye devam etmektedir. çalışmada, sarıçam örnekleri %0,25, 0,5, 1, 1,5 2,5 konsantrasyon seviyesinde çinko klorür (ZnCl2), nano seryum oksit (CeO2), (ZnO) bakır II sülfat (CuSO4) ile edilere...

Though most of the metallic ions are spermicidal in action, the present investigation emphasises the spermicidal activity of anions. Among the inorganic compounds screened at 4 concentrations (0.01%, 0.1%, 1% and 5%) halides are mainly spermicidal, except NaCl, KCl & CsCl which are spermiostatic; sulphates and nitrates are mainly spermiostatic except ZnSO4 at 1% concentration and above; CuSO4, ...

BACKGROUND Scavenger receptors are thought to be involved in the recognition of oxidized low-density lipoprotein (oxLDL) and oxidized erythrocyte (oxRBC). However, there are controversies about the kind of receptors and ligands related to the binding. Macrophages lacking class A scavenger receptor show identical binding of oxRBC with wild-type ones. METHODS RBCs were oxidized with ascorbic ac...
