We report on the synthesis of two and three dimensional carbonaceous sponges produced directly from graphene oxide (GO) into which functionalized iron nanoparticles can be introduced to render it magnetic. This simple, low cost procedure, wherein an iron polymeric resin precursor is introduced into the carbon framewor…
In this study, we electrospun novel poly(propylene carbonate)/poly(ε-caprolactone) (PPC/PCL) nanofibers with a special nanoscale topography using a simple process.
Critical thickness for ferroelectricity and the magnetoelectric effect of Co2FeAl/BaTiO3 multiferroic tunnel junctions (MFTJs) are investigated using first-principles calculations. The ferroelectric polarization of the barriers can be maintained upto a critical thickness of 1.7 nm for both the Co2/TiO2 and FeAl/TiO2 i…

Recent experiments have demonstrated that the typical nonlinear optical material K3B6O10Br can be an excellent photocatalyst under ultraviolet (UV) light irradiation. To understand the origin of the photocatalytic activity and further improve its photocatalytic efficiency to develop alternative photocatalysts, the bui…
within multilayer films. Infiltrated multilayers have shown up to 60% w/w of calcium carbonate which is comparable to structures like bones. X-ray diffraction to characterise the crystallographic structure and micromechanical testing involving nano-indentation have also been conducted. The Young's modulus of mineralis…
A novel phenomenon recently observed in the tempering of Ti-4Fe-7Al alloy, has attracted considerable attention. This phenomenon is induced by the β→α″ transformation during tempering, and its noteworthy features are rapid hardening and a shape change in a U-shaped specimen. It is of interest whether this phenomenon o…
The B(C6F5)3 catalyzed Piers-Rubinsztajn (oxysilylation) reaction of the cubic symmetry Q-cage [(HMe2SiOSiO1.5)8] with ethoxysilanes in hexane forms microporous 3-D networks coincident with ethane evolution. Slow drying provides monoliths whereas fast drying provides powders. The reaction is most efficient if initiate…
A Keggin-type hybrid polyoxometalate is used as a pure semiconductor thin film in the working electrode of a dye-sensitized solar cell fabricated with a D35 organic dye and a cobalt redox mediator system, giving a maximum IPCE of about 91% .
Porous corundum-mullite ceramics were prepared from Al(OH)3 and kaolinite gangue with different CaCO3 amount through an in-situ decomposition pore-forming technique. The effect of the amount of CaCO3 added (ACA) on the phase compositions and pore characteristics was investigated through X-ray diffractometer (XRD), sca…
A series of composite films were prepared using poly(vinyl alcohol) (PVA) and xylan as degradable raw materials under the addition of glycerol and ammonium zirconium carbonate (AZC). The influences of AZC on the mechanical properties, water‐resisting properties, thermal stability, solubility ( S ), and water vapor per…
An efficient caged phosphate charring agent named PEPA was synthesized and combined with melamine pyrophosphate (MPP) to flame-retard polypropylene (PP). The effects of MPP/PEPA on the flame retardancy and thermal degradation of PP were investigated by limiting oxygen index (LOI), vertical burning test (UL-94), cone c…
Eu 3+ doped Mg 2 TiO 4 (2 at% of Eu) nanoparticles which are 5 to 10 nm in diameter are prepared by Pechini-type polymerized complex route followed with the calcination in the temperature range from 400°C to 700°C.

The particle interface has been known to play a critical role in conventional composites. Nevertheless, the understanding of the role of interface in mechanical and thermal properties of polymer nanocomposites remains in its infancy. Similar to the previous study, two different designs of interface modification—molecu…
For the construction of a new design of mechanical heart valve a Ti-6Al-4 V alloy was selected and coated with TiO2 due to it corrosion resistance and biocompatibility. A required feature on surfaces in contact with blood it is a low level of roughness (Ra ≤ 50 nm) that not favor the formation of blood clots. One tech…
The synthesis and characterization of mono-dispersed silica hollow spheres using polystyrene (PS) spheres as template from the hydrolysis and condensation of tetraethylorthosilicate (TEOS) is presented. Successive washing steps with toluene and subsequent calcination at different temperatures were performed, in order…
We apply the Barker-Henderson (BH) perturbation theory to the study of a Lennard-Jones fluid confined in a random porous matrix formed by hard sphere particles. In order to describe the reference system needed in this perturbation scheme, the extension of the scaled particle theory (SPT) is used. The recent progress i…
In this paper, we report the possibility of utilizing nitrogen-doped graphene (N-G) as a novel cathode material for Li-ion hybrid supercapacitors (Li-HSCs) applications. N-G was prepared by a simple one-pot hydrothermal method, followed by freeze-drying in a vacuum treatment. Li-ion hybrid supercapacitors was fabricat…
