We report on the thermal stability of an ultrathin hafnium oxide film on a plasma nitrided Si(100) surface. The ultrathin silicon nitride buffer layer was produced by an ECR-plasma ion source. Onto this buffer layer a thin hafnium oxide film was prepared by electron beam evaporation. redThe therm...

The consumption of ethanol is known to increase the likelihood of oral cancer. In addition, there has been a growing concern about possible association between long term use of ethanol-containing mouthwashes and oral cancer. Acetaldehyde, known to be a carcinogen, is the first metabolite of ethan...

Increased level of serum cholesterol (hyperlipidemia) is the most significant risk factor for the development of atherosclerosis. Cholesterol levels are affected by factors such as rate of endogenous cholesterol synthesis, biliary cholesterol excretion and dietary cholesterol absorption. Acyl CoA...

A systematic study on the influence of carbon on the signal of a large number of hard-to-ionize elements (i.e. B, Be, P, S, Zn, As, Se, Pd, Cd, Sb, I, Te, Os, Ir, Pt, Au, Hg) in inductively coupled plasma - mass spectrometry has been carried out. To this end, carbon matrix effects have been evalu...

In order to develop a gas sensor with improved gas-diffusing performance, a three-dimensional (3D) hierarchical CdO nanostructure with a novel bio-inspired morphology was reported. The CdO nanostructures which exhibit a profile of natural leaveleaf were synthesized via a solvothermal approach com...

Recently, various kinds of microvalves have been developed in the field of micro total analysis systems. Most are pneumatic or piezo electric valves, which require significant space on a microchip and hence make the system complicated. This study reports the use of an electroactive polymer-based ...
