We report on a general mechanism for photo-induced phase transitions. The process relies on the photo-injection of hot electrons from an adjacent metallic layer to trigger the structural dynamics of the materials of interest. This mechanism is demonstrated for the semiconductor-to-metal phase transition of VO${}_{2}$…
Paclitaxel (Ptx), one of the most widely used anticancer agents, has demonstrated extraordinary activities against a variety of solid tumors. However, the therapeutic response of Ptx is often associated with severe side effects caused by its nonspecific cytotoxic effects and special solvents (Cremophor EL(®)). The cur…
This work presents the formation of TiO2 nanotube arrays fabricated by electrochemical anodization of titanium in the fluoride-based diethylene glycol (DEG) electrolyte, with an aim towards elucidating how variation of inter-electrode spacing affects changes in electrolyte properties and corresponding morphological fe…
Towards green material, fatigue life of epoxy and its unidirectional kenaf fibre reinforced epoxy composites were investigated. These specimens were hand lay-up made. The specimens were cycled to tension-tension fatigue loading at stress ratio of 0.5 and 5 Hz of frequency to determine the fatigue life and its life cha…
The crystallographic dependence of the DC electric (E) field induced strain and phase transition in Na0.5Bi0.5TiO3-5.6%BaTiO3 (NBT-5.6%BT) single crystals has been investigated. An induced transition between pseudocubic and tetragonal structures was observed under E = 10 kV/cm for fields applied along the 〈001〉 direct…
For the production of advanced types of catalyst support materials, the distinguished properties of graphene nanosheets were combined with the structural properties of conducting polypyrrole by the incorporation of graphene nanosheets into a polymer matrix by the proposed simple and low-cost fabrication technique. A p…
The flexoelectric effect, which describes the induction of polarization from strain gradient, is negligible in bulk but not nanometer scale ferroelectrics. The influence of flexoelectric effects on magnetic field induced electric polarizations in multiferroic nanocomposite thin bilayer films has been investigated. It…
We study heat conduction in one-, two-, and three-dimensional anharmonic lattices connected to stochastic Langevin heat baths. The interatomic potential of the lattices is double-well type, i.e., V(DW)(x)=k(2)x(2)/2+k(4)x(4)/4 with k(2)<0 and k(4)>0. We observe two different temperature regimes of transport: a high-te…
Pure and 1 mol% CuO-added lead-free potassium sodium niobate K0.5Na0.5NbO3 (KNN) ceramics were prepared by the conventional solid-state calcination method. Copper oxide was mainly used as a sintering aid in the KNN structure. Microstructural analyses clearly showed that the CuO formed a secondary phase at the grain bo…
The presence of adsorbate species on diamond surfaces, even in small concentrations, strongly influences electrical, chemical, and structural properties. Despite the technological significance, coverage of diamond by transition metals has received relatively little attention. In this paper, we present the results of d…
Abstract Summary: Biodegradation of film specimens from polyhydroxyalkanoates (PHAs) of two types – poly‐3‐hydroxybutyrate (PHB) and poly‐3‐hydroxybutyrate‐ co ‐3‐hydroxyvalerate (PHBV) – was analysed in different environments: tropical sea waters of the South China Sea (Nha Trang, Vietnam) and soils in the environs o…
In this study, Single-Walled and Multi-Walled Carbon Nanotubes in their perfect forms were investigated by the Finite Element Method. Details on the modeling of the structure are provided in this paper, including the appropriate elements, the element properties that should be defined based on the atomic structure of C…
The accurate prediction of iron losses of soft magnetic materials for various frequencies and magnetic flux densities is eminent for an enhanced design of electrical machines in automotive applications. For this purpose different phenomeno-logical iron-loss models have been proposed describing the loss generating effe…
We report the fabrication of light-sensing thin-film transistors based on solution processed films of ZnO, as the channel material, functionalized with an organic dye as the light sensitizer. Due to the presence of the dye, the hybrid devices show exceptionally high photosensitivity to green light of 106 and a maximum…
Graphene oxide filled silicone rubber nanocomposites were found to possess a large nonlinear coefficient of electrical conductivity, smaller low field conductivity than that of the neat polymer and an increase in the dielectric constant over that of the polymer matrix with a very small increase in the dielectric loss.…
Electrospun poly(ethylene terephthalate) (PET) fibers were prepared from a trifluoroacetic acid (TFA)-based solvent. Rheological studies revealed the concentration (ϕ) dependence of the specific viscosity (η sp ) to be η sp ∼ ϕ 3.7 for PET/TFA solutions in the entangled regime. The determined entanglement concentratio…
Li and H are important electrically active impurities in ZnO and this work presents a detailed experimental and computational study of the behavior of H and Li in ZnO and their effect on its defect structure. We employ AC conductivity measurements as a function of temperature and partial pressure of O 2, H 2 O, and D…
The effect of P-Phenylediamine on the corrosion behaviour of 304 stainless steel in 3M Hydrochloric acid solution contaminated with 3.5% sodium chloride was investigated using weight loss and potentiostatic polarization techniques. Corrosion parameters such as anodic and cathodic Tafel slope constants, corrosion poten…
The topic of polymer nanocomposites remains an active area of research in terms of potential applications for dielectric materials. Although more than a decade has passed since these systems were first considered as dielectric materials, the precise effects of incorporating nanofillers into different polymers are yet…
Despite advances in surgery and drug discovery, brain tumors remain fatal diseases. Early detection and diagnosis of brain tumors is of great importance for improving treatment outcomes. Magnetic resonance imaging (MRI) is a prominent, clinically-relevant imaging modality because of its excellent tissue contrast resol…
