The crystal structure of bis(nitrilo)tris(methylenephosphonato)dodecaaquatrihydrohexasodium europium(III) [EuNa6H3(H2O)12{N(CH2PO3)3}2] was determined; sp. gr. $$P\bar 1$$ P 1 ¯ , Z = 2, a = 11.0801(3) Å, b = 11.5992(3) Å, c = 14.6879(4) Å, α = 70.096(3)°, β = 77.730(2)°, γ = 80.452(2)°. The coordination polyhedron of…
Thermochromic phase transition was studied in CuMoO4 using the Cu and Mo K-edge x-ray absorption spectroscopy in the temperature range of 10–300 K. The hysteretic behavior has been evidenced from the temperature dependence of the pre-edge shoulder intensity at the Mo K-edge, indicating that the transition from brownis…
Radiation-resistant optics, which is necessary to transfer light from plasma to detectors in ITER, will be exposed to neutron fluxes at D-T stage. Achromatic lenses located in the interspace and in the port cell areas must have a sufficient optical radiation hardness to sustain a neutron irradiation without significan…
In the far-ultraviolet (UV) region, optical materials are dispersive and absorbing. The previous successful design method utilized in the visible band should be re-examined. We report on the design and fabrication of a far-UV reflective broadband filter based on dielectric materials lanthanum fluoride (LaF 3 ) and mag…
Oxide dispersion strengthened (ODS) alloys, which contain a high number density of nano-scale oxide particles, are supposed to prevent the long-range diffusion of defects therefore enhance irradiation resistance. The large amount of interfaces between oxide particles and matrix are expected to trap helium atoms as wel…
The Quantum Dots/Graphene (QDs/GR) composites have attracted numerous interests caused by its unique physical and chemical properties in past few decades. The shortages of the single QD and graphene materials could be remedied by the synergistic effects from QDs/GR composite materials; meanwhile, some unique phenomena…
Electronic Phase Separation in Iron Selenide (Li,Fe)OHFeSe Superconductor System* , Mao, Yiyuan, Li, Jun, Huan, Yulong, Yuan, Jie, Li, Zi-an, Chai, Ke, Ma, Mingwei, Ni, Shunli, Tian, Jinpeng, Liu, Shaobo, Zhou, Huaxue, Zhou, Fang, Li, Jianqi, Zhang, Guangming, Jin, Kui, Dong, Xiaoli, Zhao, Zhongxian
Even if polymers are used for decades in electronics and microelectronics, one of the primary drawbacks is their susceptibility to moisture uptake. Moisture penetrating into polymers reduces their mechanical and electrical performances and consequently, moisture becomes a reliability issue for the RDL level. This pape…
Hysteresis effect of core materials contributes sig- nificantly to the power loss and nonlinearity of the transformers and filter inductors in power electronic applications. For design or modeling of the magnetic components, information of the magnetic material’s characteristic under the desired operation condition is…
Today's power utilities are evolving towards a more environment-friendly form. Particularly, in undersea power transmission, offshore renewable energy integration and urban power transmission, HVDC cable systems play a significant role. As an essential part of the cable systems, cable joints are often the weakest and…
A method of local anodic oxidation has been used to obtain graphene-oxide regions on SiC. The change of the surface properties was confirmed by atomic-force microscopy and Raman spectroscopy. Experimental data were obtained on the conductivity, potential, and topography of the oxidized regions. It was shown that the o…
Twelve different natural raw materials were selected as possible fillers for eco-friendly biocomposites. The target was to find the most biodegradable ones. Two mycological tests were held: in the aqueous and agar media. It was found that two tests showed different results. In aqueous media, the fillers with a high co…
Calcium oxide nanoparticles and nanorods were prepared by using chemical method at two Molarities.The field emission scanning electron microscopy (FESEM) images suggested the formation of nanoparticles (50-60) nm and nanorods with diameter about 500 nm and length 3µm.The average surface roughness of CaO thin film was…
4-(Dimethylvinylsilyl)benzoic acid is obtained by organolithium synthesis. Polydimethylsiloxanes containing silicon hydride groups are modified by introducing benzoic acid fragments via the hydrosilylation reaction. The thermal and rheological properties of the copolymers formed are studied. It is found that a rise in…
Aim: The distribution and impact of aerosol-delivered gold nanoparticles (AuNPs) functionalized with a mixture of aminated-polyvinyl alcohol and amino-PEG ([polyvinyl alcohol/PEG]-NH2) upon repeated administration onto a 3D lung model were explored. Materials & methods: AuNPs were aerosolized and uptake and epithelial…
Polyvinyl alcohol polymer was dissolved in water in order to prepare films with different concentration of Fe utilizing casting method. The optical properties were obtained by recording the transmittance spectrum in the wavelength range (300-900) nm. The dispersion parameters were calculated using the Wemple–DiDomenic…
