New passive and active tags/labels are suggested to provide a long-term security identification of nuclear waste containers. An active version of the tag is based on the use of a mixture of alpha-emitting isotopes, such as Am with materials, e.g. B and Na, which easily undergo alpha-induced reactions with emission of…
The stability of the oxide layer at the surface of stainless steel is very important to protect medical implants, knowing that chemical product like hydrogen peroxide can change its behaviour. When used medical implants go through various steps in which hydrogen peroxide is involved. Corrosion of 316L stainless steel…
The inhibitive effect of a 8-hydroxyquinoline derivative (1) and the corresponding Fe 2+ chelate (2) in the corrosion of Fe in 1 M HCl was studied.The adsorption mechanism of these compounds was considered and the post-treatment effect of these compounds was studied.An increase in the concentration of compounds 1 and…
Ensuring the integrity of fuel-clad and clad-clad bonding in nuclear fuels is important for safe reactor operation and assessment of fuel performance, yet the measurement of bond strengths in actual fuels has proved challenging. The laser shockwave technique (LST) originally developed to characterize structural adhesi…

Two series of DDSQ (double-decker silsesquioxane)-containing oligomers were synthesized and their self-aggregation behaviors were investigated. Result shows that DDSQ-(C18-2A) could form well-organized lamellar structure with a d-spacing 8.2 nm. Considering the demand of microelectronic industry, this branched alkylat…
A graphene-based biopolymer is developed which exhibits saturable absorption and optical limiting behavior in the femtosecond and nanosecond regime respectively. Further this composite film when irradiated with nanosecond pulses indicates a damage threshold >50 J/cm2.
Collective mode optical Thomson scattering has been used to investigate the interactions of radially convergent ablation flows in Tungsten wire arrays. These experiments were carried out at the Magpie pulsed power facility at Imperial College, London. Analysis of the scattered spectra has provided direct evidence of a…
The unsymmetrical air flow of the dual slot die in the melt blowing process is simulated. The diameter and transverse displacement of the threadline are obtained numerically. The result shows that the threadline diameter in the unsymmetrical air flow is larger than that in the symmetrical one. This paper helps to poin…
Multiferroic Pb(Fe0.5Ti0.5)O3 is a system which has coupled co-existence of ferroelecticity and ferromagnetism at room temperature. We have been successful in synthesizing multiferroic Pb(Fe0.5Ti0.5)O3 nanoparticles of average size 36 nm using wet chemical route and studied the ferromagnetic, ferroelectric and multife…
Patterns of the thermoelectric iron silicide were fabricated on alumina substrates with a continuous-wave ytterbium fiber laser. The laser irradiation process was further examined to construct an iron silicide device without damaging the substrates upon thermal shock. The multi-step irradiation process of powder mount…
InGaAs-embedded photonic crystal photodetectors were demonstrated towards realizing photoreceivers with small junction capacitance. A 1-A/W responsivity and a 40-Gb/s eye opening were successfully confirmed for the 1.7-μm-long device.
Surface and interface analysis techniques are reviewed mainly about electron microscopy and surface analysis methods. The principal of the techniques, fundamental and preferable way of using them, some examples, and future prospects of them are presented.
Tulachan et al. found that silk cocoon membrane can generate electrical current due to ionic conduction. We argue that the current is produced by osmosis as that in a commercial osmotic plant.
Epoxy based glass fiber reinforced plastic composites G-10 CR grade are suitable material for electrical insulation breaks of the superconducting fusion device. At IPR, under the national fusion program, characterization of G-10 CR material with the neutron irradiation dose is studied. This study will help us towards…
The effect of thickness of Au buffer layer (15-25 nm) between TiO2 film and substrate on the wettability of TiO2 films is reported. TiO2 films grown on Au buffer layer have a higher contact angle of 96-;100° as compared to 47.6o for the film grown without buffer layer. The transition from hydrophobicity to hydrophilic…

Surface effects on the persistence length of quasi-one-dimensional nanomaterials are investigated by using the theory of surface elasticity and the core–shell model of nanobeams. A simple and unified expression is provided to determine the persistence length of nanowires and nanotubes with any regular polygonal cross-…
The cold testing of ITER prototype cryoline (PTCL) is part of technical qualification procedure for multi process pipe ITER cryolines. The detailed plan has been developed for the warm and cold testing of PTCL, which includes pressure and leak test at room temperature followed by cooldown of all the process pipes of P…
This work aims to investigate the glycerin from the biodiesel as fuel in the combustion synthesis into two routes, one for high temperature called direct route, in order to inhibit the formation of acrolein and compare it with the conventional combustion synthesis at low temperatures, using as fuels saccharose, pure g…
