Microwave assisted activated carbon from rubber seed pericarp (RSP) was successfully produced by using three different chemical activating agents of ZnCl2, KOH, and H3PO4. The process was carried out at 600W of irradiation power for 20 min. The absorption study was applied for these modified activated carbon samples under cationic methylene blue (MB) dye. The Carbonisation of RSP using ZnCl2 (R...

In this study, we demonstrate that OCT speckle decorrelation techniques can be used to probe intracellular motion in cancer cells. Spheroids and cell pellets were used as a model to probe intracellular motion. ZnCl2 was used to inhibit mitochondrial motion within the cells. The results reveal the changes in intracellular motion during the spheroid growth phase. Moreover, to modify the motion of...

The aim of this study was to evaluate the degree of conversion (DC%), water sorption (WS), solubility (SO), and resin-dentin bonding stability of experimental adhesive systems containing ZnCl2. Different concentrations (wt.%) of ZnCl2 were added to a model etch-and-rinse adhesive system consisting of BISGMA, HEMA, UDMA, GDMA, water, and ethanol: Zn0 (0%-control group); Zn2 (2%); Zn3.5 (3.5%); a...

A novel cyclization reaction of ethenetricarboxylate derivative aromatic compounds in the presence of various Lewis acids gave benzo-annulated cyclic compounds such as oxindole and benzofuran derivatives via Friedel-Crafts intramolecular Michael addition in high yields. For example, the reaction of diethyl 2-[(N-methyl-N-phenylcarbamoyl)methylene]malonate (1a) in the presence of ZnCl2 at room t...

DNA synthesis and adenosine(5')tetraphosphate(5')adenosine (Ap4A) levels decrease in cells treated with EDTA. The inhibitory effect of EDTA can be reversed with micromolar amounts of ZnCl2. ZnCl2 in micromolar concentrations also inhibits Ap4A hydrolase and stimulates amino acid-dependent Ap4A synthesis, suggesting that Zn2+ is modulating intracellular Ap4A pools. Serum addition to G1-arrested ...

The effects of ZnCl2 additions on a mercuric reductase, merA, ammonia monooxygenase, amoA, and hydroxylamine (NH2OH) oxidoreductase, hao, gene expression were examined in continuously cultured Nitrosomonas europaea cells. The reactor was operated for 85 days with a 6.9 d hydraulic retention time and with four successive additions of ZnCl2 achieving maximum concentrations from 3 to 90 microM Zn2...

Molten fly ashes generated from melting treatment of municipal solid waste and automobile shredder residues are characterized as hazardous waste due to the high content of heavy metals such as Zn, Pb and Cu. In addition, the heavy metal resources could be depleted in the near future and thus, the research towards conservation of metal resources is required. In the present work, volatilization b...

Biomolecular profiling with Fourier-Transform InfraRed Microscopy was performed to distinguish the Zn(2+)-mediated effects on the crustacean (Porcellio scaber) digestive glands from the ones elicited by the ZnO nanoparticles (NPs). The exposure to ZnO NPs or ZnCl2 (1500 and 4000 µg Zn/g of dry food) activated different types of metabolic pathways: some were found in the case of both substances,...

Pesticide is a pollution problem in agriculture. The usage of ZnCr2O4/CNS and H2O2 as additive liquid fertilizer has potency for catalytic pesticide degradation. Colloid condition needed easy spraying. Rice husk sawdust were used carbon precursor ZnCl2 activator. biomass–ZnCl2 mixtures pyrolyzed using microwave (400–800 W, 50 min). products dispersed water by blending then evaporated to obtain ...
