The main goal of this work is to provide a general description the negative photoconductivity effect observed in Ag/AgO films grown by spray-pyrolysis technique. X-ray diffractograms display hybrid with high texturized AgO and metallic Ag phases. Scanning electron microscopy images show small particles on surface. Due its surface nature, photoelectron spectroscopy revealed predominance characte...

Abstract The objective of the study is chemical synthesis ZnO powders, from ZnCl 2 and NaOH solutions according to an appropriate procedure. powders (a) (b) obtained underwent various characterizations such as: optical microscopy, SEM, UV, BET, IR, XRD antimicrobial activity. results showed inhomogeneous distribution, nanometric size, absorbance at 353 346 nm specific surface 25.701 30.534 cm /...

Bilirubin, the yellow substance usually responsible for neonatal jaundice, is currently monitored invasively or by observing/measuring skin colour. This paper investigates the feasibility of monitoring serum bilirubin concentration using light absorbance in a similar fashion to pulse oximetry. The light absorbance of bilirubin is shown to be sufficiently different to haemoglobin to in theory al...

The methods of (14)C-2-deoxyglucose ((14)C-2DG) metabolic mapping and optical intrinsic signal (OIS) imaging were used to evaluate the response evoked in the contralateral primary somatosensory receiving areas (SI and SII) of anesthetized cats by either 25 Hz ("flutter") or 200 Hz ("vibration") sinusoidal vertical skin displacement stimulation of the central pad on the distal forepaw. Unilatera...
