Methods were developed for the preparation of biotinylated trypsin of high specific activity. This was used as a probe for the detection of serine proteinase inhibitory proteins which had been separated by sodium dodecyl ...

Gold is the material of first choice for the realisation of a large number of interesting nanoscale devices and structures due to its unique chemical and optical properties. However, conventional photolithographic processes ...

In this study, the settled floc (sludge) produced by aluminum sulfate (Al2(SO4)3), ferric chloride (FeCl3) and titanium tetrachloride (TiCl4) flocculation was recycled with a novel flocculation process, which has a significant ...

PACS 42.55.Px, 78.55.Cr, 78.60.Hk Cathodoluminescence is applied for evaluation of in-plane variations of light emission from GaN-based laser diode structures. We demonstrate that potential fluctuations affect significantly ...

A pseudo-isothermal method for the kinetic analysis was applied to the recrystallisation of α to β nickel sulphide based on the Ozawa model for non-isothermal crystallisation in the presence of pre-existing nuclei. The ...

This paper reviews the isolation, structure elucidation, proposed biosynthesis and biological activities of the small, but increasing, number of pyrido[1,2-a]azepine Stemona alkaloids.

A method for quantitative analysis of biological soft tissues by laser ablation-inductively coupled plasma-mass spectrometry has been developed. Polymer film standards were produced by spin coating spiked solutions of poly ...

X-ray mapping using energy dispersive spectroscopy or wavelength dispersive spectroscopy is a very popular characterisation tool for determining the elemental distribution in materials. Furthermore, quantitative X-ray ...

This study demonstrates the application of quantitative elemental bio-imaging for the determination of the distribution Cu, Mn, Fe and Zn in Parkinsonism mouse model brains. Elevated concentrations of these metals within ...

There is a strong need for techniques enabling direct assessment of biological activity of biofouling in membrane filtration systems. Here we present a new quantitative and non-destructive method for mapping O2 dynamics ...
