The creation of nanoporous Cu 3 Sn–Cu–Cu 6 Sn 5 composite structures in the form of self-supporting foils through the concurrence of de-alloying and re-alloying.
A conducting solid biodegradable polymer electrolytes based carboxymethyl cellulose (CMC) doped ammonium thiocyanate (NH4SCN) system with concentration in the range 0 – 25 wt.% of NH4SCN have been prepared via solution casting method. The impedance study of CMC-NH4SCN system was measured via Electrical Impedance Spect…

A mechanical strain occurring during the drilling or punching of a hole on electrical sheets will cause deterioration of the magnetic characteristics around the hole. The result is that, when the sheet is magnetized parallel to the edge, the magnetic flux density has changed its orientation around the hole. In this pa…
A strategy for the development of novel nanocomposite films based on azopolymer and sol–gel synthesized silver-containing titanium oxide nanoparticles with different photoinduced birefringent properties is reported.
Using the density functional theory plus Hubbard Hamiltonian we have investigated the spin up/down electronic band structure, density of states, electronic charge density distribution and the dispersion of the optical properties of microcrystalline β-RbNd(MoO 4 ) 2 .
A 2D segment model for a bi-layer electrolyte solid oxide fuel cell (SOFC) is developed by coupling the mass transport in the channel and electrode, electrochemical reaction at the electrode/electrolyte interface and charge transport in the bi-layer electrolyte.The Butler-Volmer equation is used to describe the electr…
In this paper, uniformly distributed CdSe and CdTe quantum dots (QDs) are deposited simultaneously on the surface of TiO 2 nanorods via electrochemical atomic layer deposition (ECALD) method. XRD and TEM characterization confirm that the deposits are the composite of CdSe and CdTe QDs. SEM observation presents that th…
We report the synthesis of novel LiFe 0.2 Co 0.8 O 2 2D nanomeshes which demonstrate enhanced performance as cathode materials for Li ion batteries, resulting from the porous structure and the introduction of conductive Fe.
Rheological properties of epoxy compounds containing pernigraniline and emeraldine forms of polyaniline were studied. The emeraldine form of polyaniline catalyzes the curing of epoxy compounds. The influence of the emeraldine and pernigraniline forms of polyaniline on the glass transition point of epoxy polymeric mate…
Natural kaoline without any further modification was used as a novel catalyst for the facile green ring-opening polymerization of l -lactide.
The majority of engineering steels are ferromagnetic and structurally inhomogeneous on scales ranging from nanometers to micrometers, and their physical properties depend on the three-dimensional (3D) features in their microstructures. Thus, obtaining a 3D image with a large field of view is desirable for transmission…
Guest editors Zhiqun Lin, Nam-Gyu Park and Gang Li introduce this Journal of Materials Chemistry A themed issue on perovskite solar cells.
The higher-order structure and the formations of SC and HC of the PLLA/PDLA blend melt-electrospun fibers collected on a rotating target were investigated. The diameter of the fiber decreased and the orientation factor increased with increasing take-up velocity. The formation of SC was promoted with decreasing fiber d…
The total attenuation coefficients of 11 biological targets against photon energies were plotted within the energy range 1-10 MeV. From these plots a possible equation describing the relationship between photon energy and the total attenuation coefficient was derived. The suggested equation is mu/ rho = 0.0696/ surd E…
The current investigations deal with the effect of concentration of CeO 2 nanoparticles (NPs) on physical properties of ferroelectric liquid crystal.
The formation of a single-crystal silicon polytype is observed in silicon-on-sapphire structures by high-resolution transmission electron microscopy. The appearance of inclusions with a structure different from that of diamond is attributed to the formation of strong-twinning regions and the aggregation of stacking fa…
In this paper, we study the electrical and thermal conductivities of multi-walled carbon nanotube (MWCNT)/DI-water composites via first order phase transition. Around 0 °C, the contrast ratio of electrical and thermal conductivities reaches 1250 and 3.58 times, with PTC and NTC effects respectively.
The dissociation and recombination rates of physisorbed H2, and the direct and steady state dissociation (i.e., the precursor mediated dissociation) rates of gas phase H2 on Ni(111), as well as the corresponding kinetic isotope effects, are calculated using the quantum instanton method, together with path integral Mon…
Piezoelectric actuators and sensors are widely used for flow control valves, including diesel injectors, ultrasound generation, optical positioning, printing, pumps, and locks. Degradation and failure of material and electrical properties at high temperature typically limits these applications to operating temperature…
