The elastic stiffness coefficients of single crystal AlLi with cubic NaTl (B32) structure were calculated at 0 K from the first principles. The obtained elastic stiffness coefficients, in units of GPa, were c11=66.9, c12=38.2 and c44=51.7. Then the bulk modulus, Young’s modulus, shear modulus and Poison’s ratio were e…
In order to confirm and demonstrate Oxide Dispersion Strengthened (ODS) cladding fuel pin survival to high burn-up condition, an irradiation test in BOR-60 was conducted within the framework of JNC-Russian RIAR collaborative work. Two types of 9Cr martensitic and 12Cr ferritic ODS steel claddings were manufactured in…
High cycle fatigue properties of high strength steel were investigated. In the Fuel Cell(FC) system, various metals are used in hydrogen environment under cyclic loading. In this study, hydrogen was artificially charged into specimen of a Cr-Mo high strength steel, and the fatigue properties were compared with those o…
Recent optical measurements on single‐walled carbon nanotubes (SWCNT) showed highly anomalous behaviors indicating strong many‐electron effects. To understand these data, we performed ab initio calculation of electron‐hole interaction (excitonic) effects on the optical spectra of several SWCNTs. We employed a many‐ele…
Cardiovascular disease remains the number one cause of death in the United States. Most current surgical procedures to alleviate this disease rely on the availability of suitable small diameter vascular grafts, which are constrained by several limitations. Tissue engineering brings new hope to this field, but still fa…
On account of the search for the optimal composition and structure-phase state of Zr alloys much attention is paid to upgrade the E110 (Zr-1 %Nb) and E635 (Zr-1 %Nb-0.35 %Fe-1.2 %Sn) alloys that have proved well in terms of irradiation-induced creep and growth, high strength characteristics, and corrosion. The differe…
The corrosion and hydriding behavior of M5 and low tin Zircaloy-4 in PWR have been compared at high burn-ups (>70 GWd/t). Whereas low tin Zircaloy-4 reached about 90 µm in oxide thickness and is subjected to significant precipitation of hydride rims at the metal/oxide interface, the oxide layer on M5 remains be…
A novel catalyst for the Fenton reaction was prepared by immobilizing Fe(III) onto collagen fiber and its high activity as a catalyst for degradation of dyes under irradiation of UVC was proved.
In the presence of ethanol, insulin forms amyloid morphologically distinct from the ambient specimen. Due to stability of fibrils and the autocatalytic character of the process, the two amyloid templates, when seeded, replicate the initial morphologies (and inter-beta-strand hydrogen bonding patterns) regardless of th…
One of the advantages of ultracapacitors is its high power capability, which is applicable for high rate of charging and discharging operation like motor starting and regenerative braking of an electric vehicle. This paper presents a new charging method for ultracapacitors. Comparing with batteries, ultracapacitor can…
A new route to form multiple morphologies was outlined using amphiphilic graft copolymers with interesting biological and pharmacological properties by proper adjustment of backbone and graft chain length.
The effect of texture on magnetic properties by adding specific elements of tin, antimony and boron was investigated. Texture factor was defined as the ratio of the sum of cube and Goss textures to γ fibre. Tin and antimony showed larger effect in enhancing grain size than boron for both hot rolled and cold rolled ban…
Ordered cubic Fd3m mesoporous silica monoliths (HOM-11) were fabricated by using lyotropic and microemulsion phases of block copolymers (EOm–POn–EOm) as templates. Aromatic and aliphatic hydrocarbon molecules were used in the formation of true microemulsion liquid crystal phases, in the expansion of pore sizes, and in…

Thin diamond-like carbon (DLC) coatings deposited by DC or RF magnetron sputtering of a graphite target in argon/methane ambients, and nanocrystalline diamond/amorphous carbon (NCD/a-C) films prepared by microwave plasma chemical vapour deposition (MWCVD) from methane/nitrogen mixtures were investigated with respect t…
The South Korean company, NessCap Co., is one of the about 10 makers of ultracapacitor, devices that can store so much charge that they are beginning to blur the functional distinction between the capacitor and the battery. They offer a unit rated at an impressive 5000 farads at 27 volts in a package a little bigger t…

Ignalina NPP Unit 1 with the RBMK-1500 type reactor enters the preparatory stage for its decommissioning. A big volume of graphite has to be dismantled and managed. This paper evaluates the composition of radionuclides in irradiated graphite on the basis of the calculation scheme with computer codes MCNPX and CINDER'9…
CeO2 (cubic fluorite) thin films have been deposited on no-rolled Hastelloy C276 substrates by metal-organic chemical vapour deposition (MOCVD) from the Ce(hfa)3·diglyme [Hhfa = 1,1,1,5,5,5-hexafluoro-2,4-pentanedione; diglyme = (CH3O(CH2CH2O)2CH3)] precursor. The X-ray patterns of all samples grown in the 350–550 °C…
