High level Liquid Waste (HLW) is generated during the reprocessing of spent nuclear fuel which is used to recover uranium and plutonium. More than 99% of the radioactivity generated during the burning of nuclear fuel in the reactor is present in HLW. For the efficient management of HLW either by vitrification in the suitable borosilicate glass matrix, or partitioning and transmutation (P&T) of ...

Recent two dimensional nuclear magnetic resonance (NMR) techniques access exchange in pore structures through surface relaxation and diffusion based relaxation [1-4]. This research applies these techniques to measure pore changes due to biofilm growth and the impact this growth has on diffusion transport. The porous media used in this study are model beadpacks constructed from borosilicate glas...

Pyrochlore-based glass-ceramics are attracting attention as a promising host material for immobilizing minor actinide in high-level wastes. However, the loading capacity of pyrochlore-based materials elements is to be improved, and only conventional synthetic approaches powder sintering glassy bulk crystallization were reported. Here, new (La,Y)2(Zr,Ti)2O7 subtly designed successfully prepared ...

We report the fabrication and the optical characterization of a hybrid tunable integrated optical filter. It consists of a diffused ion-exchanged channel waveguide on a borosilicate glass substrate with a cover of the same glass to form a gap filled with a holographic grating. The grating morphology, called POLICRYPS (POlymer LIquid CRYstal Polymer Slices), is made of alternating stripes of pol...

As powder bed based additive manufacturing (AM) is gaining more traction in the research and industry, significant efforts are made to expand capability of AM combining different materials. Conventionally, multiple materials, sealants processes necessary order join metal glasses assemblies. The development a single-step process for vacuum-tight strong bonding between glass could drastically red...

The steady-state zero output of static electric field measuring systems often fluctuates, which is caused mainly by the finite leakage resistance of the water film on the surface of the electric field microsensor package. The water adsorption has been calculated using the Boltzmann distribution equation at various relative humidities for borosilicate glass and polytetrafluoroethylene surfaces. ...

We demonstrate a method for measuring elastic back-scattering patterns from single laser trapped micron-sized particles, spanning the scattering angle range of θ=167.7°-180° and φ=0°-360° in spherical coordinates. We calibrated the apparatus by capturing light-scattering patterns of 10 μm diameter borosilicate glass microspheres and comparing their scattered intensities with Lorenz-Mie theory. ...

In the present research work, effect of several process parameters on the machining characteristics of borosilicate glass has been reported. The machining characteristics that are being investigated are material removal rate (MRR) and tool wear rate (TWR). Four different process parameters were considered for this study power rating of the machine, static load, slurry concentration and abrasive...
