This paper describes technology of the electromagnetic valve made in the LTCC (Low Temperature Co-fired Ceramics). The actuation is supplied by mutual reaction between a 3D coil and a neodymium magnet bonded to flexible membrane. Such solution has many advantages like short reaction time, small power consumption and r…
The treatment of peripheral nerve injuries is still one of the most challenging tasks in neurosurgery, as functional recovery is rarely satisfactory in these patients. The concept behind the use of biodegradable nerve guides is that no foreign material should be left in place after the device has fulfilled its task, s…
Poly(ethylene adipte) and poly(ethylene adipate)/silica nanocomposite (PEAd/SiO2) containing 3 wt. % SiO2 were prepared by an in situ method. The examinations on the non-isothermal crystallization kinetic behavior have been conducted by means of differential scanning calorimeter (DSC). The Avrami, Ozawa, and combined…
Material-based solutions,such as metal organic frameworks (MOFs),continue to attract an increasing attention as viable options for hydrogen storage applications.MOFs are widely regarded as promising materials for hydrogen storage due to their high surface areas,porosities,and tunability of the pores and functionality…
Nous avons étudié la cohérence excitonique dans le poly[N- 9’-heptadecanyl-2,7-carbazole-alt-5,5-(4,7-di-2-thienyl-2’,1’,3’-benzothiadiazole] (PCDTBT). À l’aide d’un modulateur spatial de lumière, nous avons forgé des impulsions lasers ultracourtes permettant de sonder les cohérences du système. Nous nous sommes conce…

The weak fixation of biomaterials within the bone structure is one of the major reasons of implants failures. Calcium phosphate (CaP) coatings are used in bone tissue engineering to improve implant osseointegration by enhancing cellular adhesion, proliferation and differentiation, leading to a tight and stable junctio…
These last years Ion Beam Analysis users show an interest in High Energy Alpha beams[1]. These beams can be used for on-site analysis by means of radioactive sources e.g. for space application but they also offer a powerful combination of properties for the analysis of thick layers (about 10 to 20 µm). This kind of la…
This short report presents the neutronic analysis to evaluate the impact of fission product impurity on the Pu content of Sodium-cooled Fast Reactor (SFR) metal- and oxide- fuel fabrication. The similar work has been previously done for PWR MOX fuel [1]. The analysis will be performed based on the assumption that the…
The Savannah River National Laboratory (SRNL) has evaluated the existing waste feed qualification strategy for the Hanford Tank Waste Treatment and Immobilization Plant (WTP) based on experience from the Savannah River Site (SRS) Defense Waste Processing Facility (DWPF) waste qualification program. The current waste q…
This data package contains the K Basin sludge characterization results obtained by Pacific Northwest National Laboratory during processing and analysis of four sludge core samples collected from Engineered Container SCS-CON-210 in 2010 as requested by CH2M Hill Plateau Remediation Company. Sample processing requiremen…
본 연구에서는 carboxylated SBR latex와 zinc oxide가 SBS 복합재의 내마모성과 debris 특성 개선에 미치는 영향을 관찰하였다. 실리카를 첨가한 SBS 복합재는 실리카 입자간의 수소 결합에 의한 강한 filler-filler interaction으로 인한 낮은 분산성 때문에 기계적 강도, NBS 내마모성, debris 특성이 전체적으로 감소하는 것으로 나타났다. carboxylated SBR latex를 첨가한 SBS 복합재는 carboxyl group과 실리카의 silanol group간의 결합을 통하여 filler-filler int…
In article the question of approach to design of selective repair of defective sections of linear part of the main oil pipelines as to the area demanding optimization is brought up. The problem of congestion of the design institutes which are engaged in development of documentation on objects of pipeline transport is…
Bulk (RE)BCO materials can be used potentially as powerful permanent magnets. The magnetic flux distribution above a bulk HTS magnet, however, is strongly non-uniform (conic profile predicted by the Bean model) compared to the rather flat distribution above a ferromagnet. In the present work, we study how FeNi soft fe…
The relatively weak mechanical properties of hydrogels remain a major drawback for their application as load-bearing tissue scaffolds. Previously, we developed cell-laden double-network (DN) hydrogels that were composed of photocrosslinkable gellan gum (GG) and gelatin. Further research into the materials as tissue sc…
The physics of foams, droplets and bubbles describes and explains the intricacies of the materials we see all around us, which range from a sugary meringue to an opal.
The article found that the distribution of the normal components of the along the length of the samples has no significant features associated with different magnetic characteristics, so the magnetization modes of an additive powder on the details of uncertain chemical composition must be installed on the tangential c…
The hexagonal ferrites, also know as hexaferrites, have become massively important materials commercially and technologically, accounting for the bulk of the total magnetic materials manufactured globally, and they have a multitude of uses and applications. They all have a magnetocrystalline anisotropy; that is the in…

This Technical Evaluation Report provides details of preliminary testing/experiments performed using a handheld X-ray fluorescence analyzer. The analyzer will be utilized in upcoming fuel-foil-rolling optimization studies at the INL. The studies are being performed in support of DOE’s Office of Global Threat Reduction…
