We have studied formation of carbon nanoparticles using Ar+CH 4 high pressure nanosecond discharge non-thermal plasmas. Transition pressure from uniform glow discharges to filamentary ones was clarified to obtain conditions under which uniform glow discharges are sustained. We have produced nanoparticles using the glo…
In Japan, high level radioactive waste (HLW) produced by reprocessing spent fuels has been planned to be fixed in the glass solid body which is enclosed in the stainless steel canister which is further enclosed in the metal overpack. The overpacks are emplaced in tunnels at a deep underground facility. Carbon steel is…
We study the particle scale response of a 2D frictionless disk system to bulk forcing via cyclic shear with reversal amplitude γ_{r}. We find a subdiffusive γ_{r}-dependent regime, which is consistent with models of anomalous diffusion with scale-invariant cage dynamics, and a crossover to diffusive grain motion at hi…
We theoretically investigate the transport properties of bilayer graphene junctions, where the ferromagnetic strips are attached to the middle region of the graphene sheet. In these junctions, we can control the band gap and the band structure of the bilayer graphene by using the bias voltage between the layers and th…
It is shown that low-pressure DC discharge treatment of PTFE films at both the anode and cathode leads to substantial enhancement of the contact properties of the polymer surface and alters considerably the adhesion properties of PTFE film surface. A procedure is developed for determination the adhesion characteristic…
This study deals with the eff ect of dye-sublimation printing on the performance of underwear. Two groups of polyester knitted fabrics were analysed. The change of tree selected groups of properties was investigated before and after the application of dye-sublimation printing, namely durability (breaking force and elo…
Abstract Ta 3 Ru 5 B 2 , Zr 2.86(5) Ru 5.14(5) B 2 , and Hf 2.83(2) Ru 5.17(2) B 2 have been successfully synthesized as polycrystalline powders as well as single crystals and characterized by powder and single‐crystal X‐ray diffraction and EDX analysis. Furthermore, their electronic structures and bonding characteris…
Small changes in the synthesis of MnAs nanoparticles lead to materials with distinct behavior. Samples prepared by slow heating to 523 K (type-A) exhibit the characteristic magnetostructural transition from the ferromagnetic hexagonal (α) to the paramagnetic orthorhombic (β) phase of bulk MnAs at Tp = 312 K, whereas t…
We investigated the phase transformations of amorphous solid acetone under confined geometry by preparing acetone films trapped in amorphous solid water (ASW) or CCl4. Reflection absorption infrared spectroscopy (RAIRS) and temperature-programmed desorption (TPD) were used to monitor the phase changes of the acetone s…
Abstract BACKGROUND Environmental regulations are moving to tighter control of NOx emissions produced at both stationary and mobile sources. Selective catalytic reduction ( SCR ) of NOx with NH 3 is an efficient treatment technique capable of operating at high gas flow rates (e.g. using monolithic catalysts) and a wid…
Theoretical and experimental studies of the director distribution of a chiral nematic liquid crystal placed in a wedge-shaped cell with weak surface anchoring were performed. We measured local value of pitch as function of position inside each Grandjean-Cano zone by registering selective reflection spectra from narrow…
Abstract A series of new rare‐earth cadmium metal tellurite chlorides were synthesized by the salt flux technique and characterized by single‐crystal X‐ray diffraction. The new compounds CdSm 2 (TeO 3 ) 2 Cl 4 ( I ), CdEu 2 (TeO 3 ) 2 Cl 4 ( II ), and CdGd 2 (TeO 3 ) 2 Cl 4 ( III ), adopt layered structures correspond…
This paper investigates the separation possibilities of model emulsion oil-in-water using polypropylene fibre bed coalescence. Experiments were carried out over a wide range of physico-chemical characteristics of mineral oils, bed permeability and operating fluid velocities. The aim of this study was to analyse the in…
Dedicated integrated experiments have been used to determine in situ the corrosion rate of carbon steels in geological repository mock-ups (90°C, anaerobic, slow synthetic water flux…). Electrochemical impedance spectroscopy (EIS) measurements were performed, allowing for the extraction of instantaneous corrosion rate…
Abstract A convenient approach for the straightforward synthesis of highly dispersed silver nanoparticles (below 5 nm) in a carbon or silicon dioxide matrix through twin polymerization is reported. The obtained mainly microporous carbon (type I isotherm) and mesoporous silica materials (type IV isotherm) exhibit a rat…
Abstract The crystal structures of synthesized d–f hybrid tetranuclear heterometal Zn II 2 Eu III 2 and Cd II 2 Eu III 2 complexes, involving a pair of carboxylate ligands in a rare μ 4 ‐η 2 :η 2 bridging mode, reveal that the metal centers are arranged alternately in a rhombic plane within 4 Å from each other. The Zn…
ABSTRACT β‐Cyclodextrins/polyacrylonitrile/copper nanorods (β‐CDs/PAN/CuNRs) composite fibers were fabricated by two steps including the preparation for the β‐CDs/PAN composite fibers by electrospining, and the preparation of the β‐CDs/PAN/CuNRs composite fibers by adsorption and reduction. The β‐CDs/PAN/CuNRs composi…
Nanoparticle surface enhanced Raman scattering (SERS) tags have attracted interest as labels for use in a variety of applications, including biomolecular assays. An obstacle to progress in this area is a lack of standardized approaches to compare the brightness of different SERS tags within and between laboratories. H…
The negatively charged nitrogen-vacancy (N-V(-)) color center in diamond is an important solid-state single photon source for applications to quantum communication and distributed quantum computation. Its full usefulness relies on sufficient radiative emission of the optical photons which requires realizable control t…
The catalyst of Ni 2 B nanoparticles was successfully prepared using nickel and boron as precursors with the quenching gas in radio frequency thermal plasmas. The generating of Ni 2 B needs adequate reaction temperature and boron content in precursors. The quenching gas is beneficial for the synthesis of Ni 2 B in RF…
