This study was carried out in two stages. In the first stage; 2-oxo-2-phenylethyl-2-aminobenzoate (OPA) compound, which an aniline derivative, synthesized by starting appropriate components. Then, poly(OPA) obtained via chemical polymerization of OPA presence ammonium peroxydisulfate (APS) as initiator and DMF solvent. Poly(OPA)/Bentonite (BNT) nanocomposite effectively dispersing inorganic nan...
the present research designed to evaluate the effects of foliar application of methyl jasmonate (meja), salicylic acid (sa) and potassium sulfate on improving fruit quality and photosynthesis system. ten treatments include: sa (0.3, 0.6 and 0.9 mm), meja (0.5, 1 and 2 mm), potassium sulfate (0.5, 1 and 1.5%) and distilled water (control) were sprayed on pomegranate trees 2 and 7 weeks after ful...
The objective of this study was determining the most limiting plant growth factor in the wheat root zone dominated by illite in clay fraction and a high specific surface with ample ammonium acetate extractible potassium. A completely randomized block design with 4 replicates was used in Seyed Miran Research Farm (Gorgan) during 2009-2010 growing season. Treatments were mineral fertilizers (to a...
Polymeric carbon nitride (PCN) has great potential for peroxydisulfate (PDS) activation but still challenge due to the sluggish electron-hole pair dissociation and tardy charge transfer dynamics. Herein, a novel PCN-based donor-acceptor conjugated polymer (PCN/4-MI D-A) is synthesized by copolymerization of urea 4-methoxyphenyl isothiocyanate. The obtained PCN/4-MI D-A exhibited significantly i...
Abstract In this study, low-cost siderite was used to activate peroxydisulfate (PDS, S2O82-)-inactivated Enterococcus faecalis study the inactivation characteristics and mechanism of siderite/PDS. The results showed that siderite/PDS had a better effect on at pH 3. sterilization increases with increase dosage, PDS concentration temperature. rate is decreased initial bacterial concentration. Ino...
In the present study, response of Pistachio (Pistacia vera L.) on nitrate reductase activity, some biochemical characters and ions accumulation to salinity were evaluated. Salinity treatments (0, 75, 150 mM NaCl) and potassium nitrate (0, 10, 15 mM) were imposed and sampling were done 100 days after treatments. Results indicated that sodium chloride at 75 mM plus 10 mM potassium nitrate resulte...
In this research, novel conductive nanocomposites containing urethane acrylate (UA) andpolyaniline/copper (II) oxide nanocomposites (PANi-CuO) were synthesized. At firstpolyaniline/CuO nanocomposites with different amount of CuOnanoparticleswere prepared bychemical oxidationpolymerization of aniline using ammonium peroxydisulfate as an oxidizingagent. Afterward, UA-PANi-...
background in contemporary practice, acute mesenteric ischemia (ami) remains a serious cause of morbidity and mortality in abdominal emergencies. objectives we report the measurement of peritoneal fluid potassium and ph on a small series of rats that developed extensive ami following the surgical ligation of superior mesenteric vessels and compare the results with control groups. materials and ...
