Oligothiophene-proline hybrids were synthesized via click-reaction showing intriguing self-assembly behavior in an aqueous environment by forming chiral superstructures, whose helicity is controlled by the configuration of the amino acid moiety.
The fabrication of nano porous silicon, nPSi, using alkali etching process has been studied and carried out. The surface chemistry of anisotropic etching of n-type Si-wafer is reviewed and the anisotropic chemical etching of silicon in alkaline solution using wetting agents is discussed. Transformation of crystallogra…
Redox responsive nanotubes were fabricated by the template assisted layer-by-layer (LbL) assembly method and employed as platforms for molecular payload release. Positively and negatively charged organometallic poly(ferrocenylsilane)s (PFS) were used to construct the nanotubes, in combination with other polyions. Duri…
A sensitive and simple method for the determination of chelerythrine (CHE) was developed based on the fluorescence quenching effect of CHE for glutathione (GSH)-capped CdTe/CdS quantum dots (QDs). Under optimum conditions, a good linear relationship was obtained from 0.073 to 24.0 μg mL−1 with a correlation coefficien…
Hypervelocity-impact experiments are performed on SiO2 glass plates to investigate its damage process. The damage propagation behavior induced by a hypervelocity impact is observed using a high-speed video camera. The postmortem observations reveal that the damage structure of the impacted plates consists mainly of cr…
As-synthesized Pd/MCM-41 and Au/MCM-41 including the residual SDA organic templates, cetyltrimethylammonium bromide (CTABr), within the mesoporous channels exhibit superior catalytic activities than the conventionally calcined ones without templates, owing to the stabilizing effect of metal nanoparticles, concentratio…
Nanometer sized ZnO clusters are produced in the gas phase and subsequently deposited on clean Au(111) surfaces under ultra-high vacuum conditions. The zinc blende atomic structure of the approximately spherical ZnO clusters is resolved by high resolution scanning transmission electron microscopy. The large band gap a…

In this paper, we successfully synthesized amino-terminated poly(ethylene glycol)-block-poly (epsilon-caprolactone) (NH2-PEG-PCL) block copolymer from polyethylene glycol 2000, epsilon-caprolactone (epsilon-CL) and hydrazine hydrate. The obtained copolymer was characterized by nuclear magnetic resonance (1H-NMR), the…
Aurivillius phase (Li,Ce) doped CaBi4Ti4O15 (CBT) ceramics were prepared using the conventional solid state methods. The crystal structure and microstructure were determined by X-ray diffraction and scanning electron microscopy. It was found that the (Li,Ce) ions diffused into the A site of CBT's pseudo-perovskite str…
The hierarchic structure of short glass fiber reinforced isotactic polypropylene (GF/iPP) composites with β-nucleating agent were investigated by wide-angle X-ray diffraction, differential scanning calorimetry, polarized light microscopy and scanning electronic microscopy measurements. It was found that the content of…
Ceramic materials such as silicon carbide (SiC) are promising candidate materials for nuclear fuel cladding and are of interest as part of a potential accident tolerant fuel design due to its high temperature strength, dimensional stability under irradiation, corrosion resistance, and lower neutron absorption cross-se…
Abstract Owing to socio-cultural and safety concerns, fishgelatin is considered to be a potential alternative tomammalian gelatin. The purpose of the currentstudy was to investigate how functional propertiesof fish gelatin are influenced at different environ-mental conditions such as pH and NaCl concentra-tions. The f…
The aim of this study was to evaluate the possibility of using some models developed to study the plant-bacteria interaction mechanisms for the assessment of the impact of chronic exposure to nanoparticles. Rice-associated bacteria showed that some models are sensitive to the presence of NPs and allow a quantification…
The results of an inter laboratory comparison of thermal diffusivity measurements on two different materials, namely a copper alloy (CuCrZr) and a polymer (PMMA), are presented here. Both materials were selected with respect to their different thermal conductivity, since the copper alloy belongs to the family of good…
Novel austenitic steel of which composition is Fe–20Cr–30Ni–2Nb (at%) is one of the promising material for further advanced steam power plants, which will be operated at 973 K or higher temperature such as 1073 K. This steel is strengthened by intermetallic compounds and has creep rupture strength 80 MPa at 973 K for…
In Fe–C–V–W–Cr–Mo high speed steels, the nature of carbides during the solidification are discussed as a function of C, V and W content by the help of Partial Equilibrium (PE) approximation and thermodynamic calculations. The results show that the solidification path and carbide precipitation can be reasonably predict…
The emulsion explosive is one of the important industrial explosives. The structural stability of the water-in-oil (W/O) emulsion matrix of an emulsion explosive determines the reliability of its initiation, safety and detonation performance. It is known that the emulsifier is one of the most important factors affecti…
Three Mg–Zn–Y ternary alloys in the vicinity of X, W and H phases were prepared and were isothermally heat treated at 833, 793, 723 and 673 K to attain thermodynamic equilibrium. The microstructure was observed using electron probe microanalysis and transmission electron microscopy, and the chemical compositions of th…
Exposure to bioaerosols at various stages of waste management system (collection, transfer and disposal) has been evaluated by recording of the bacterial and fungal concentrations in the air around these facilities. Regardless of the season, the total bacteria and total fungi were detected for all samples, whereas the…
