Abstract Contact with groundwater in the disposal geological site will induce creation of an amorphous corrosion layer on high-level radioactive glass. This is connected to silicate saturation conditions surrounding medium, and it influenced significantly by geochemical processes near-field minerals at that depth. The international simple glass a six-oxide borosilicate commonly used nuclear int...

Petroleum products and essential oils are produced used in large amounts categorized as Substances of Unknown or Variable composition, Complex reaction Biological materials (UVCBs). These UVCBs notorious difficult-to-test substances, since they complex mixtures hydrophobic volatile compounds. This study introduces two passive dosing (PD) approaches for whole UVCB toxicity testing: (1) headspace...

We present a numerical investigation of energy and charge distributions during electron-beam-induced growth of tungsten nanostructures on SiO2 substrates by using a Monte Carlo simulation of the electron transport. This study gives a quantitative insight into the deposition of energy and charge in the substrate and in the already existing metallic nanostructures in the presence of the electron ...

Several methodologies have been devised for the design of nanomaterials. The "Holy Grail" for materials scientists is the cost-effective, eco-friendly synthesis of nanomaterials with controlled sizes, shapes and compositions, as these features confer to the as-produced nanocrystals unique properties making them appropriate candidates for valuable bio-applications. The present review summarizes ...

FIG.1 Composition diagram showing natural and synthetic crystalline materials (dark blue circles) based on LiO1/2, LiN1/3, PO5/2, and PN5/3 starting materials. The light blue circles indicate compositions of LiPON materials reported in the literature. The black squares indicate stable idealized phosphate chain structures having the composition of ηLi2PO2N + (1-η)LiPO3 studied in this work. Intr...

Magnetic nanorods or nanowires exhibit degrees of freedom associated with their inherent shape anisotropy and the ability to incorporate different components along their length. The introduction of multiple segments along the length of a nanowire can lead to further degrees of freedom associated with the shape of each segment and the coupling between layers. In this paper, we present an overvie...

Continuous postoperative nocturnal pulse oximetry was performed in 20 patients undergoing elective cholecystectomy to examine if the composition of anaesthetic gas mixtures affects postoperative gas exchange. The patients were allocated randomly to receive either nitrogen or nitrous oxide during anaesthesia, and oximetry was performed on the night before operation and the first and third nights...

OBJECTIVE To study the oxygen saturation profile in normal Asian Indian eyes. DESIGN A cross sectional prospective study. SUBJECTS Ninety eight consecutive patients presenting to our hospital with best corrected distance visual acuity (BCVA) of 20/20 and a normal ophthalmic examination were included in the study. Patients having any ocular or systemic disease were excluded from the study. ...

In this Chapter lipids extracted from charred and non-charred surface residues are quantitatively compared to lipids absorbed into the ceramic material of the vessel. The emphasis is on ceramic vessels originating from Uitgeest-Groot Dorregeest, but charred surface residues from other Roman Iron Age settlements and from Neolithic sites were analysed for comparison using Gas Chromatography and G...
