The aim of the research presented here was to identify the chemical form of 14C in irradiated graphite. A greater understanding of the chemical form of this longest-lived isotope in irradiated graphite will inform not only management of legacy waste, but also development of next generation gas-cooled reactors. Approxi…
Lithium ion batteries nowadays dominate the market of high power energy storage devices [1]. One of the crucial points for next generation lithium batteries and dual-ion cells for stationary energy storage is the development of lithium salts with enhanced electrochemical stability and without corrosive impact at Al cu…
Lithium is relative expensive and will be exhaust one day due to the limitation of lithium resources on the earth. In contrast to lithium, sodium is more abundant and lower cost of sodium-containing precursors, leading to sodium-ion battery is a promising energy storage device for large-scale systems. 1-3 In the prese…
This chapter summarizes recent devellopment of electrochemical sensors based on functionlized mesoporous silica materials. The nanomatrials based sensors have been developed for sensitive and selective enrironmental detection of toxic heavy metal and uranium ions.
Silicon is known to have large Li storage capacity up to 4.4 Li atoms per Si atom in Li22Si5 compounds, but the large volume change and the mechanical stress during the charge-discharge cycles have damaged the electrode structures leading to rapid capacity fade. Recently, Cui et al. have applied the silicon nanowire s…
Li-ion batteries have contributed to the commercial success of portable electronics and may soon dominate the electric transportation market provided that major scientific advances including new materials and concepts are developed. Layered oxides of the general formula LiNi1/3Co1/3Mn1/3O2, termed as NMC, display the…
Lithium sulfur batteries attract great attention due to their high energy density, while the real applications are still hindered by the rapid capacity degradation. Despite great effort devoted to solving the polysulfide shuttle between the cathode and anode electrodes, it remains as a serious challenge to build high-…
The caption to Fig. 4(a) states that the data shown are for k B T=J 1.2. Actually, the temperature is k B T=J 2.0. This does not have any effect on the conclusions of the Letter.
This technical letter report provides the status of an assessment undertaken by PNNL at the request of the NRC to verify the capability of periodic ASME-required volumetric examinations of reactor vessels to characterize the density and distribution of flaws of interest for applying §50.61a on a plant-by-plant basis.…
The polymer bonded explosive TCV is analogous to PBX compositions used in some nuclear weapons where the PBX will be exposed to high energy ionising gamma radiation. It is therefore important to study how gamma radiation affects the mechanical and chemical properties of the PBX. In this study 60Co was used to irradiat…

There is an increasing interest to develop nanoscale biocompatible graphene structures due to their desirable physicochemical properties, unlimited application opportunities and scalable production. Here we report the preparation, characterization and biocompatibility assessment of novel graphene flakes and their enab…
Development of the 2nd generation ATF FeCrAl alloy has been initiated, and a candidate alloy was selected for trial tube fabrication through hot-extrusion and gun-drilling processes. Four alloys based on Fe-13Cr-4.5Al-0.15Y in weight percent were newly cast with minor alloying additions of Mo, Si, Nb, and C to promote…
Recent reports on the fabrication of phosphorene, i.e., mono- or few-layer black phosphorus, have raised exciting prospects of an outstanding two-dimensional (2D) material that exhibits excellent properties for nanodevice applications. Here we study by first-principles calculations the adsorption of CO, CO2, NH3, NO a…
Polyphosphazene based polymer electrolytes exhibit excellent thermal and electrochemical properties accompanied by a high stability versus lithium metal anodes [1]. The combination of the cross-linked polymer matrix with electrolytes based on organic carbonates or ionic liquids leads to ionic conductivities of 1 mS/cm…
The paper presents the current trends in medicine of regenerative tissue defect caused by resection of tumors or fractures.Although it is a relatively young field of science, it creates new possibilities for the reconstruction of pathologically altered tissue with the use of three-dimensional scaffolds.Tissue engineer…
Neste trabalho, fez-se em estudo experimental das deformacoes residuais oriundas do processo de soldagem. Deste estudo conclui-se que as deformacoes permanentes maximas ocorrem no inicio do processo de soldagem. As deformacoes apresentaram-se heterogenea ao longo do comprimento da chapa. Os resultados aqui apresentado…
By die-attaching GaN-based light-emitting diodes (LEDs) on Si substrates with eutectic AuSn solder, the external quantum efficiency of the LEDs was enhanced by 3.5% at a current input of 120 A/cm2. The enhancement of the external quantum efficiency of the die-attached LED chips is attributed to a reduction in compress…
The features of thermal methods for the determination of kinetic parameters of oxidation of carbon materials are considered in the article. A modified method for the determination of kinetic parameters on the basis of the quantities characterizing the steady state of a system is suggested.
