High aspect ratio (50 : 1), 10 μm long, multifunctional and electrically conductive nanobundles are templated via conformal oxidative chemical vapor deposition (oCVD) of a copolymer of 3,4-ethylenedioxythiophene (EDOT) and 3-thiopheneethanol (3TE). The presence of –OH groups provides a platform, as depicted by covalen…

Luminescent CdS quantum dots have been embedded on the tapes or matrices obtained by the self-assembly of two synthetic short peptides. The X-ray crystallography reveals that both the peptides exhibit a turn-like structure in the solid state and form an intermolecular hydrogen bonded dimer. In higher order assembly, t…
The formation of nanoporous palladium-silver (NPPS) structure through galvanic replacement reaction (GRR) of nanoporous silver (NPS) and palladium (II) nitrate is monitored by chronopotentiometry. During the GRR, the potential of the NPS varied with time from the formal potential of the Ag(I)/Ag couple toward that of…
Aqueous dispersions of γ-alumina powder synthesized by homogeneous precipitation (HP) were investigated and compared with a commercial gamma alumina (TM300). As the isoelectric point (IEP) of the two powders was found to be at the same pH (8.5), the rheological properties of the suspensions were determined under contr…
The alkaline niobate-based perovskite ceramics (Li,Na,K)(Nb,Ta,Sb)O3 has been regarded as a new candidate of lead-free piezoelectric materials due to its excellent piezoelectric properties. In this study, Li0.02(Na0.55K0.45)0.98(Nb0.77Ta0.18Sb0.05)O3 (abbreviated as LNKNTS) piezoelectric ceramics were fabricated by a…
Ultra-high-frequency (UHF) approaches have caught increasing attention recently and have been considered as a promising technology for online monitoring partial discharge (PD) signals. This paper presents a Peano fractal antenna for UHF PD online monitoring of transformer with small size and multiband. The approximate…
Porous resorbable implants are of great interest since they may deliver bioactives or drugs, facilitate the transport of body fluids or degradation products and provide a favorable environment for cell attachment and growth. In this work we report on a method using concentrated emulsions to template interconnected sol…

Various features of Silicon micro and nanostructures have been produced by lasers. Laser micromachining of silicon wafer has been conducted to fabricate devices for microelectronic circuits. The laser beam initiates a chemical reaction between the silicon and HF acid to synthesize porous layers by a laser-induced etch…
Two novel ZnO nanostructures were successfully synthesized using a carbon thermal evaporation process catalyzed by Au films and a AgNO3 solution, respectively. The morphologies were characterized in detail and show pendant necklace-shaped and bead necklace-shaped nanostructures. A new growth mechanism is stated to exp…
Electrohydrodynamic (EHD) destabilisation of a lamellar-forming block-copolymer (BCP) film gives rise to hierarchical pattern formation on the micrometre and 10 nm length scale in one single step. Two BCP morphologies were found in the columns that formed from a homogeneous surface instability. At low electric field s…
High-temperature, pressure-shear plate impact experiments have been conducted to investigate rate-controlling mechanisms for plastic deformation of high-purity aluminum at high strain rates (106 s-1) and at temperatures approaching melt. The objective of these experiments was to look for a possible change in the rate-…
We show that the cytotoxic effect of carbon nanotubes (CNTs) on bacteria is mediated by mechanical damage to the cell wall and membrane. Two β-galactosidase-producing strains of Escherichia coli harboringgenomically integrated reporter gene constructs, namely pchbB:lacZand prpoS:lacZ, were used for the purpose. We fir…
The influences of boron addition on the phase formation, Curie temperature and magnetic entropy change of the Mn0.95Fe1.05P0.5As0.5 compound have been investigated. All the samples crystallize in the hexagonal Fe2P-type structure and boron enters into the basal plane as an interstitial element. The Curie temperatures…
The proposed approach to validation of steam sterilization in autoclaves follows the basic life cycle concepts applicable to all validation programs. Understand the function of sterilization process, develop and understand the cycles to carry out the process, and define a suitable test or series of tests to confirm th…
Waste natural rubber latex was blended with polystyrene (WNRL/PS) for recycling. A mixture with a 50/50 ratio of rubber to PS was blended by an internal mixer (Haake) at 140 °C and 60 rpm. The PS became the matrix, and the WNRL was dispersed within the matrix. Dynamically vulcanized natural rubber/PS (NRv/PS) blends a…
We approach a green method in the production of alkylaromatic ketones over hexagonally ordered mesoporous CrSBA-15 catalysts, which were used, in green routes, in the liquid-phase oxidation of alkylaromatics. A promising chemical treatment method was used with ammonium acetate solution to remove the toxic nature of no…
Up to third-generation sterically crowded polyether dendrons were prepared on a solid support, using a novel building block derived from dimethyl 5-hydroxyisophthalate via O-allylation/Claisen rearrangement key steps. These dendrons underwent smooth disassembly to monomers, when subjected to acidic solution. The reaso…
Al-doped Mg0.5(1+x)AlxTi2−x(PO4)3 has been prepared by a sol–gel method and the conductivity has been evaluated by an ac impedance method to determine the optimum lattice volume for Mg-ion conduction. Instead of using Ti in the samples, 10–15 mol%Al was used, resulting in lattice contraction in the c-axis direction. T…
