abstract balanced nutrition and soil organic mater are among most important factors affecting yield and quality of grape (vitis vinifera cv.peykani). humic acid as an organic acid derived from humus and other organic sources, in accompany with zinc, and acetic acid can reduce deficiency symptoms in grape. to study the effects of zinc, humic acid and acetic acid on yield and yield components, an...

in this study, the ultrasonic, photocatalytic and sonophotocatalytic degradation of organics in textile industrial effluent was studied using zno nano catalyst, zno nano catalyst was synthesized by using sol-gel method. the structure and morphology of the catalyst were investigated using scanning election microscopy (sem), electron dispersive x-ray spectroscopy (eds) and x-ray diffraction patte...

the aim of the present study was to investigate the possibility of improvingproductive performance and immunity of growing japanese quailreared during summer in egypt by supplementing the diets with organic zinc (bioplex zinc) and prebiotic (mannan oligosaccharides). diets were a basal diet or the basal diet supplemented with 20 mg bioplex zinc (3.0 mg zn) (zn1), 40 mg bioplex zinc (6.0 mg zn) ...

Tightening quality standards for European waters has seen a move towards enhanced wastewater treatment technologies such as granulated organic carbon treatment and ozonation. Although these technologies are likely to be successful in degrading certain micro-organic contaminants, these may also destroy compounds which would otherwise complex and render metals significantly less toxic. This study...

metal-organic frameworks (mofs) represent a new class of highly porous materials. on this regard,  two nano porous metal-organic frameworks of [zn2(1,4-bdc)2(h2o)2∙(dmf)2]n (1) and [zn2(1,4-bdc)2(dabco)]·4dmf·1⁄2h2o (2), (1,4-bdc = benzene-1,4-dicarboxylate, dabco = 1,4-diazabicyclo[2.2.2]octane and dmf = n,n-dimethylformamide) were synthesized and characterized. they were used for preparation ...

The complexation of zinc by natural organic ligands in the upper 600 m of the central North Pacific was determined with differential pulse anodic stripping voltammetry at a thin mercury film, rotating glassy-carbon disk electrode. Of the dissolved zinc in surface waters >98% was bound in strong complexes (log Klcond, =“z+ = 11 .O) by relatively zinc-specific organic ligands existing at low conc...

the effect of different levels of zinc and copper organic supplements on performance, plasma copper plus zinc status, serum alkaline phosphatase (alp), ceruloplasmin (cp) activity as well as vitamin ¬a concentration was studied in 25 mehraban male lambs each of 5-6 months of age and 30/64±3/47kg of live weight. the following five dietary treatments were used: 1) control (base diet with no addit...

We succeeded to fabricate p-n heterojunction and bulkheterojunction small-molecular-weight organic thin-film solar cells by combination of dry (p-type = zinc phthalocyanine, n-type = fullerene) and wet (p-type = tetra-tert-butyl zinc phthalocyanine, n-type = [6,6]-phenylC61-buteric acid methyl ester) processes. Relationship between morphologies of semiconducting layers and photovoltaic properti...
