phosalone, malathion and diazinon were analyzed in corn oil using solid phase extraction (spe)with lanthanum silicate as a new solid sorbent followed by gas chromatography with nitrogenphosphorus detection (gc-npd). the efficiency of different eluents (methanol, dichloromethane,ethyl acetate, dichloromethane — ethyl acetate (1:1) and ethyl acetate — methanol (1:1)) werecompared for elution of o...

This work reports on the nanoscale assembly of hybrid lanthanum oxide and silica structures, which form patterns of interfacial dense and porous networks. It was found that increasing the molar ratio of lanthanum nitrate to tetraethyl orthosilicate (TEOS) in an acid catalysed sol-gel process alters the expected microporous metal oxide silica structure to a predominantly mesoporous structure abo...

Novel Fe(3)O(4)@La(x)Si(y)O(5) affinity microspheres consisting of a superparamagnetic Fe(3)O(4) core and an amorphous lanthanum silicate shell have been synthesized. The core-shell-structured Fe(3)O(4)@La(x)Si(y)O(5) microspheres, with a mean size of ca. 480 nm, had rough lanthanum silicate surfaces and displayed relatively strong magnetism (47.2 emu g(-1)). This novel affinity material can be...

Lithium–lanthanum silicate oxyapatite exhibits high lithium-ion conductivity at temperatures above 400 °C. To further enhance its ionic conductivity, the relationships among microstructure, bulk and grain boundary were investigated for Li-rich compositions. LixLa10−xSi6O27−x (x = 1–8), Li5La5Si5O20, Li5La5Si4.5O19, Li6La4Si4.5O18, Li7La3Si4O16 synthesized, their conductivities determined. Using...

The interaction between proteins and membranes has an important role in biological pro-cesses.We have calculated energies of interaction between Melittin and DMPC bilayer in differenttemperatures. We have used the CHARMM software for MD simulation under the canonical (N,V, E) ensemble at different temperatures. The computations have shown that water moleculeshave more penetration into the bilay...

This work presents a characterization of the electrical properties of thulium silicate thin films, within the scope of a possible application as IL (interfacial layer) in scaled high-k/metal gate CMOS technology. Silicate formation is investigated over a wide temperature range (500–900 C) through integration in MOS capacitor structures and analysis of the resulting electrical properties. The re...
