in this research, acute toxicity (lc) of zinc oxide nanoparticle on beluga (huso huso) andcommon carp (cyprinus carpio) was studied. the experiment was conducted using theorganization for economic co-operation and development (no. 202) method. for bothspecies, 96hlc10 was determined to be more than 200 mg/l. to assess the effects of zinc oxidenanoparticles on blood factors, leukocyte index coun...

The search for active catalysts that efficiently oxidize methane under ambient conditions remains a challenging task for both C1 utilization and atmospheric cleansing. Here, we show that when the particle size of zinc oxide is reduced down to the nanoscale, it exhibits high activity for methane oxidation under simulated sunlight illumination, and nano silver decoration further enhances the phot...

Disclosed is a method of preparing pigmentary chromium oxide nano particles having 50 percent particle size less than about 100 nm. Preparation of nano chromium (III) oxide is investigated by thermal decomposition method. According to the disclosed method, a substantially dry solid composition of potassium dichromate and carbon active is heated in CO2 atmosphere to a temperature of about 60...

Zinc oxide nanoparticles are highly sensitive towards phosphate ions even at pH 7. Buffer solutions and cell culture media containing phosphate ions are able to destroy ZnO nanoparticles within a time span from less than one hour to one day. The driving force of the reaction is the formation of zinc phosphate of very low solubility. The morphology of the zinc oxide particles has only a minor in...

In the current investigation, an attempt is made to synthesize and characterize Citrullus colocynthis stem extract loaded Zinc Oxide Nano Particles (ZnONP-Cc) evaluate cytotoxicity antimicrobial activities of same. The synthesis ZnONP-Cc was carried out characterization in terms UV-Spectrum, Fourier Transform Infra-Red (FT-IR) spectrum, Transmission Electron Microscope (TEM), X-Ray Diffraction ...
