The micro-alloying of 1 at% metals of Au-Group (Ag, Au) and the Pt-Group (Ni, Pd, Pt) with the Ti60Cu40 amorphous alloy resulted in the formation of fine nanoporous copper (NPC) in the order of 6–28 nm. The smallest characteristic pore size of open–cell nanoporous fcc Cu was 7 and 6 nm after dealloying the amorphous T…
A novel single-molecule magnet (SMM) of trans-substituted Tb(III) porphyrin, {[Tb(BIPPP)2](DBU-H)} (BIPPP: 5,15-bis(3,5-isopentoxyphenyl)porphyrin, DBU: 1,8-diazabicyclo[5.4.0]undec-7-ene), is reported here. The alternating current magnetic susceptibility measurements showed the frequency dependence on the in-phase an…
Recently, the need of secondary battery application continues to increase. The secondary battery which using a liquid electrolyte was indicated had some weakness. A solid polymer electrolyte is an alternative electrolytes membrane which developed in order to replace the liquid electrolyte type. In the present study, t…
The paper presents research on use of magnetostrictive cores for the recovery of energy from vibrations and its use to power low-power electronics. To achieve this goal a test stand was constructed to generate and to receive the vibrations in the measurement system at the same time. Selection of an appropriate magneto…
Neutron and X-ray diffraction are key techniques that are used to investigate the atomic and nanometric mesoscale structure of glasses and amorphous materials. These experimental methods probe the nuclear (neutron) or atomic (X-ray) pair correlation func- tions between atoms. For a glass containing N atom types, the i…
Metal-containing ionic liquids comprising cationic Pd(II) chelate complexes and the bis(trifluoromethanesulfonyl)amide (Tf2N) anion were prepared: [Pd(acac)(Me4en)]Tf2N (1), [Pd(acac)(BuMe3en)]Tf2N (2), and [Pd(C8-acac)(Me4en)]Tf2N (3) (acac = 2,4-pentanedionate, C8-acac = 3-octyl-2,4-pentanedionate, Me4en = N,N,N',N'…
The effect of cryogenic treatment on the plastic property of Ti-6Al-4V plate was studied in the present work. After cryogenic treatment, the low temperature temper at 180 ▭ was conducted in one of the groups and the results were compared with that of the untreated and cryotreated ones. The SLX series program controlle…
Summary This paper describes the study of lipid DPPC, carried out on setup for simultaneous investigations by P–V–T and SANS methods. The data allowed us to calculate in area per lipid molecule changes during the lipid phase transition from ripple phase to liquid‐crystalline phase.
Epoxidised natural rubber/polyvinyl chloride (ENR/PVC) thin film composite membrane was prepared by using solution casting technique. Tetrahydrofuran (THF) and rice husk (RH) were respectively used as solvent and reinforcing filler. Effects of RH loadings (0, 1, 2 and 5% wt/wt) in the casting solution on morphology an…
Low energy mixing and higher LiH content effectively destabilize AB for enhanced hydrogen release at a desirable temperature.
The production of nitrogen-doped porous carbons in an air oven at 750 °C with high surface area (≥500 m2 g−1), carbonization yield up to 35 wt% and tuneable nitrogen content from ionic liquids was reported. It utilized inorganic halide salts as the reaction medium, the activation agents, and the physical barrier. This…
Pinning effect on crystalline Be x Zn 1−x O alloy films on Al 2 O 3 (0001).
This work predicts the elastic modulus tensor, equation of state, and coefficients of thermal expansion at all stable thermodynamic states for γ-RDX. The work provides substantial material information for continuum modeling of RDX.
Experimental delta-mu spectra for the H oxidated and the propene co-fed Au nanoparticles were reproduced with XANES simulations with FEFF9. The results support that the propene has pi back-bonding to the Au with binding at defects or steps or in very small nanoparticles. Cationic, or even better, the neutrally charged…
Abstract Cu-Al-Be-Mn shape memory alloys in the range of 9.2-15 wt.% of Aluminum and 0.1-4 wt.% of Beryllium and 0.1-2 wt% of manganese, exhibiting β-phase at high temperatures and manifesting shape memory effect upon quenching to lower temperatures, were prepared through ingot metallurgy. The alloy ingots were homoge…
The paper is concerned with the modeling of reactive powder concrete (RPC) by using the method of numerical homogenization. More specifically, a two-scale modeling approach and the finite element method are used. The behavior of a model of RPC on the macro scale is described on the basis of the phenomena occurring in…
Let f(z) = z + ∑(n=2)(∞) (a)n(z) (n) be analytic in the unit disk with the second coefficient a2 satisfying |a2| = 2b, 0 ≤ b ≤ 1. Sharp radius of Janowski starlikeness is obtained for functions f whose nth coefficient satisfies |a(n)| ≤ cn + d (c, d ≥ 0) or |a(n)| ≤ c/n (c > 0 and n ≥ 3). Other radius constants are al…
A facile and biosynthetic microbial method to produce N-doped graphene nanosheets is described.
The use of ductile irons for structural applications is increasing thanks to their interesting mechanical properties, which can be combined with the casting technology to manufacture components having complex geometries. Mechanical properties can be adjusted by varying the chemical composition and the heat treatment p…
A two-step electrochemical anodization was used to form the anodic aluminum oxide (AAO) thin films with nanotube arrays of self-organized honeycomb structure. Al foil was anodized in 10% sulfuric acid (H2SO4) and 3% oxalic acid (H2C2O4) at 25°C at constant voltage of 40 V for 60 min for two times. Ethylene glycol (C2H…
