Reductive cleavage of C(6)F(5)SeSeC(6)F(5) with elemental M (M = Zn, Cd, and Hg) in pyridine results in the formation of (py)(2)Zn(SeC(6)F(5))(2), (py)(2)Cd(SeC(6)F(5))(2), and Hg(SeC(6)F(5))(2). Structural characterization of the Zn and Cd compounds reveals tetrahedral coordination environments, while the Hg compound…
This paper presents the adjoint variable method (AVM) for finite-element (FE) analysis of eddy current problems based on complex variables. In the sensitivity analysis based on FE analysis of time-harmonic eddy current fields, the functions for which sensitivity is evaluated are often real-valued, while unknown variab…
Experimental evidence shows that small Cu(2)O nanoparticles exhibit ferromagnetic or paramagnetic properties, allowing for the promising possibility to recycle the catalyst Cu(2)O easily in wastewater treatment. In this paper, theoretical calculation studying the magnetic property of copper/oxide clusters is reported.…
We report molecular dynamics simulations of the effect of the photoisomerization of probe molecules on the nonequilibrium dynamics of a bulk amorphous matrix. Is it the matrix or the probe that drives the dynamics in SRG formation? In the first picture, the probe isomerization induces the motion of the probe inside th…
Abstract Ti 3 AlC 2 has the properties of ceramics and metals. These excellent properties indicate that Ti 3 AlC 2 is a very promising material to extensive applications. Ti 3 AlC 2 ceramic material was prepared by mechanical alloying. The effects of milling time and sintering temperature on the fracture, microstructu…
Spectral shifts in stochastic beam-like fields on interaction with layers of positive- and negative-phase materials are examined on the basis of the ABCD-matrix approach and generalized Huygens-Fresnel principle. It is found that boundaries between such materials may cause spectral switches. Effect of absorption of ne…
Hydrothermally prepared mesoporous silica gel (prepared under acidic condition) was calcined at different temperatures to control concentration of surface hydroxyl groups. These materials were functionalized with 3-aminopropyltrimethoxysilane (APTMS) and used for the adsorption of Cu 2+ ions. Adsorption isotherm and a…
We have studied the correlation between the structural distortion and the magnetic interaction change in the ferrimagnetic $(\text{Lu},L){\text{Fe}}_{2}{\text{O}}_{4}$ ($L=\text{Y}$ and Er) by using neutron powder diffraction and x-ray magnetic circular dichroism (XMCD). The Rietveld profile refinements revealed that…
Abstract Gas atomized 4J36 alloy powder was milled for 72 h then mixed with ZrW 2 O 8 powder and sintered at 600°C for 4 h under argon atmosphere. 4J36/ZrW 2 O 8 composites containing 10 vol.%, 20 vol.%, 30 vol.%, and 40 vol.% ZrW 2 O 8 were fabricated, the relative density of which ranged from 70% to 80%. Thermal exp…
In this paper, transformation optics is presented together with a generalization of invisibility cloaking: instead of an empty region of space, an inhomogeneous structure is transformed via Pendry's map in order to give, to any object hidden in the central hole of the cloak, a completely arbitrary appearance. Other il…
Abstract The effects of small amounts of the rare‐earth element erbium on the microstructure and the mechanical properties of AZ31 magnesium alloy via the electromagnetic stirring (EMS) process have been studied. It has been shown that AZ31‐Er alloys are mainly composed of α‐Mg solid solution and β‐Mg 17 Al 12 phases.…
The present investigation concerns plasma-keyhole welding of UNS S32760 super-duplex stainless steel. Apart from Argon, a mixture of argon with 2 vol% nitrogen was used in both plasma and shielding gas, in order to improve the austenite/ferrite balance. Keyhole welding with argon provides with a narrow fusion zone wit…
Hot compressive deformation behavior of ZK60 magnesium alloy was investigated at the temperature range from 523 to 673 K and strain rate range from 0.001 to 1 s−1 on Gleeble-1500 thermal simulator. The results show that flow stress of ZK60 magnesium alloy decreases with the increase of deformation temperature and the…

Abstract A series of chromophoric Lewis base adducts of methyltrioxorhenium (MTO) was examined. The ligands were pyridine derivatives with different size of the aromatic system and variable substituents, thus providing a variation of electronic and steric parameters. The complexes were fully characterised (UV/Vis, IR…
We studied the methanol adsorption behavior of Pt nanoparticles that were vacuum-deposited on a TiO(2)(110) surface at room temperature by using an ultrahigh vacuum (UHV) scanning tunneling microscope (STM). A large number of bright spots were observed on fivefold-coordinated Ti (Ti(5c)) rows of the TiO(2)(110) surfac…
We studied very large graphene/Ru systems by ab initio calculations. It is shown that the graphene monolayer on Ru is nearly flat rather than strongly corrugated. The large corrugation is found to be unfavorable and disagrees with the observed bias dependence of scanning tunnel microscope images. The C-Ru bonds are me…
We study the interplay between proximity-induced superconductivity and ferromagnetism in graphene by self-consistently solving the Bogoliubov de Gennes equations on the honeycomb lattice. We find that a strong triplet proximity effect is generated in graphene, leading to odd-frequency pairing correlations. These odd-f…
For the present work, a heat‐set microfibre polyester woven fabric was treated with five different sodium hydroxide concentrations in similar conditions. Their physical and mechanical properties were studied and discussed. Changes in eight properties due to the weight reduction, i.e. surface properties, tear strength,…
