The spectral imagings were performed in order to examine the lateral resolution of the EDX analysis which is attached in an ultra low acceleration voltage SEM. The spectral imagings were performed for the cross section of the Ni coating on Al, which was cut using microtome, and the cross section of GaAs/AlAs super-lattice, which was cleavaged, using a ultra-low-acceleration-voltage SEM and EDX....

CONTEXT Telomeres are biomarkers of biological aging. Shorter telomeres have been associated with increased adiposity in adults. However, this relationship remains unclear in children and adolescents. OBJECTIVE To evaluate the association between telomere length (TL) and adiposity markers in overweight/obese adolescents after an intensive program. We hypothesize that greater TL at baseline wo...

CONTEXT Deterioration of metabolic syndrome (MetS) has been associated with short telomere length (TL). Large-scale longitudinal studies with repeated measures of MetS and TL are lacking. OBJECTIVES We examined whether baseline MetS components predict TL over time, and whether deteriorations in MetS parallel telomere attrition. DESIGN AND SETTING Participants were part of The Netherlands St...

To establish a rapid trace-quantification scheme for elements contained in highly purified tungsten, we studied the most suitable conditions for separating the elements using solid-phase-extraction as a pretreatment for inductively coupled plasma-mass spectrometry (ICP-MS). We used chemically bonded silica gels belonging to the functional group of benzylsulfonic acid as extracting agent. Tungst...

The thermoluminescence (TL) properties of CVD diamond film irradiated with b rays and illuminated with UV and visible light (200–450 nm) have been studied. The film (23mm) was grown for 47 h on monocrystalline silicon. The TL glow curves are similar for b irradiation and short wavelength UV light. The b dose response curves and UV light time response curves exhibit linear–supralinear–sublinear ...

The cold metal transfer (CMT) welding-brazing process was chosen to join Al alloy and Ni-coated steel using AlSi12 as the filler wire. macrostructure microstructure of joints were tested by an optical microscope (OM), scanning electron (SEM), energy dispersive spectrometry (EDS), X-ray diffraction (XRD). tensile properties corrosion also tested. results showed that Ni coating could improve wett...

In an attempt to control the film composition, factors affecting the composition of Ni-Fe alloy deposits and their crystal structure have been analyzed as a function of bath composition, cathode current density, bath pH, temperature and an addition of citric acid. antimony electrode revealed that the deposition potential of Fe coincides with the potential where the abrupt increase of pH was obs...

In the recent years, not much environmental monitoring has been conducted in the territory of Kosovo. This study represents the first comprehensive monitoring of the drinking water situation throughout most of the territory of Kosovo. We present the distribution of major and minor trace elements in drinking water samples from Kosovo. During our study we collected 951 samples from four different...

in the present study, ni-p-cnt composite coating was successfully fabricated via electroless plating. scanning electron microscopy (sem) was used to characterize the coatings. the effect of cnts concentration in the bath on its content in the composite coatings was studied. furthermore, the corrosion behaviour of the coatings with different contents of cnts was evaluated using tafel polarizatio...
