Superparamagnetic colloidal plates were synthesized from tetrabutylammonium stabilized Ca(2)Nb(3)O(10) nanosheets and oleic acid-stabilized Fe(3)O(4) nanoparticles. Modification with 3-aminopropyltrimethoxysilane produces amine-terminated Ca(2)Nb(3)O(10) with an amine concentration of 0.43 +/- 0.06 groups per Ca(2)Nb(3)O(10) unit as follows from spectroscopic quantification with trinitrobenzene...

Synthesis of BaTiO 3 /Au core-shell nanocavities. The principle of the synthesis of BaTiO3/Au core-shell nanocavities is shown in Fig. S1. All chemicals were of reagent-grade purity and were purchased from Sigma-Aldrich unless specified. 100 nm tetragonal BaTiO 3 nanoparticles were provided by Paul Bowen of the Powder Technology Laboratory at EPFL. Ultraviolet spectroscopy indicated a band gap ...

The effect of a TEI enhancer mixed system consisting of triethanolamine (T), ethanol (E) and isopropyl myristate (IPM) on the skin permeation of acidic, basic and neutral drugs were evaluated in vitro using excised hairless rat skin. The binary enhancer system consisting of IPM and ethanol (El) produced marked improvement on the penetration of all the drugs tested. When T was added to the EI sy...

In recent years, the effects of heterogeneous catalysts for the oxidation of organic and inorganic pollutants in industrial wastewaters are spread. Traditionally, these reactions are usually carried out using suspensions of photo-catalysts such as TiO2. A chemical method including TiCl4, Al(NO3)3, ethanol amine, ethyl acetoacetate and aqueous ammonia were used for the fabrication of TiO2-Al2O3 ...

Phaseolus vulgaris is one of the most widely used traditional remedies for diabetes mellitus. Over a thousand medicinal plants have been found to contain anti-diabetic chemicals, bulk which long in medicine. The pharmacological significance eating diabetics has intensively explored order identify several bioactive components responsible their diabetes-controlling benefits. Researchers previousl...

Sarcophrynium brachyatachys, commonly known as Yoruba soft cane or the praying plant, is traditionally used for packaging food items. Only a few natives recognize usefulness of leaves treatment cough and bronchitis in herbal medicine. This study was designed to isolate characterize bioactive component. Successful percolation carried out with 96 percent ethanol get crude extract. Afterwards, fra...

This study was designed to explore phytochemical screening and antimicrobial activity of the Eucalyptus globulus. Extraction performed by Soxhlet apparatus using ethanol hot water extraction water. The ethanolic extract showed presence alkaloids, carbohydrates, saponins, phenols, tannins, flavonoids, terpenoids, proteins & amino acids, steroids, volatile oils, aqueous glycosides, gums mucil...
