Understanding the thermal decomposition effects in TOPO capped ZnO nanocrystals
CrystEngComm, 2012Different shapes and sizes of TOPO-capped ZnO nanostructures have been obtained by the decomposition of the cupferron complex in the presence of tri-n-octylphosphine oxide (TOPO) under different conditions. The precursor : TOPO ratio, the order of reactants and thermal decomposition temperature play important roles in determining of the shape and size ...

The enduring demand for ever-increasing storage capacities inspires the development of new few nanometer-sized, high-performance memory devices. In this work, tri-n-octylphosphine oxide (TOPO)-stabilized sub-10 nm monoclinic HfO2 nanocrystals (NC) with a rod-like and spherical shape are synthesized and used to build up microscale and nanoscale test ...

Effect of oxidation-reduction on the extraction of uranium from wet phosphoric acid by DEHPA/TOPO
Journal of Radioanalytical and Nuclear Chemistry Articles, 1995Uranium is recovered from wet phosphoric acid by DEHPA/TOPO in kerosene. Uranium is present in wet phosphoric acid in the tetravalent and hexavalent states but DEHPA/TOPO extracts uranium in the hexavalent state only. The ratio of U4+/U6+ depends on several factors such as the origin of the phosphate rock, the method of preparation of phosphoric acid ...

This study examined the effect of globalization on organizational staffing using Administrative Staff College of Nigeria (ASCON), Topo-Badagry, Lagos State as a study. Global forces like technology, information communication, culture and politics are transforming organizations worldwide, though the level of transformation varies from organization to ...

Relative computability in the effective topos
Mathematical Proceedings of the Cambridge Philosophical Society, 1989Let ℕ be the natural numbers object in , the effective topos. It was shown in [1] that the maps ℕ → ℕ are (internally or externally) just the total recursive functions. Now a subset A ⊆ ω of natural numbers corresponds to a ¬¬-closed subobject A ↣ ℕ; let kA be the least topology forcing A to be decidable, and let ℕA be the sheafification of ℕ with ...

The soil types and woody vegetation of Weenen Nature Reserve (WNR), KwaZulu-Natal, were described. Mispah, overlying shale, and Shortlands, overlying dolerite were the most common of 18 the soil forms encountered. Six vegetation types were identified by TWINSPAN which differed in slope, aspect, land-use history, species richness and tree density ...

Antitumor activity and the mechanism of CPUY013, a novel Topo I inhibitor, on gastric adenocarcinoma BGC823 cells were studied in vitro and in vivo. The proliferation was investigated by MTT assay and colony formation assay. Apoptosis was determined by both dual fluorescence staining with AO and EB and DNA agarose gel electrophoresis analysis methods ...
