The encapsulation of individual nanoparticles has gained great attention as a method for both stabilizing nanoparticles and tailoring their surface properties. In particular, the encapsulation of nanoparticles with silica shells is advantageous for bioconjugation and applications to (nano)biotechnology. Herein we repo…
Abstract Nanocrystalline diamond (NCD) films were grown by microwave plasma CVD in hydrogen‐based gas mixture. Deposition experiments were performed at different temperatures varying from 370 to 1100 °C. Before growth step, silicon (100) oriented substrates were nucleated by bias enhanced nucleation procedure and glas…
Abstract Three series of novel modified polyazomethines were prepared with mesogenic units and varying kinking groups. The effect of the incorporation of the kinking groups on the thermotropic properties of the alternated and random polymers was studied. Structural elucidation was carried out by elemental analysis, in…
In this review, we report on the newly developed area of research devoted to the formation of self-assembled monolayers of metallophthalocyanines by focusing on some significant examples dedicated to electroanalytical applications. We also summarize recent examples on the use of electropolymerized metallophthalocyanin…
Chitosan/silica hybrids (Chitosan/SiO2) using a sol-gel process were prepared at a wide range of in situ silica content from 0% to 100%. This work was undertaken to investigate the thermal properties, optical, adsorption, and biodegradability properties of this type of hybrid. Fourier transform infrared (FTIR) spectra…
Abstract Conductive polymer composites (CPCs) can be obtained by blending an insulating polymer matrix with conductive fillers. When the percolation of the dispersed particles is achieved, it is possible to obtain a sensible material for self‐regulated heating by the Joule effect. To fit the durable development concep…
Nanotechnology, the design and manipulation of materials at the atomic scale, may well revolutionize many of the ways our society manufactures products, produces energy, and treats diseases. Innovative nanotechnology products are already reaching the market in a wide variety of consumer products. Some of the observed…
Near edge x-ray absorption fine structure (NEXAFS) spectroscopy has been employed to obtain the temperature dependent evolution of the electronic structure of acid treated carbon nanotubes, which were further modified by dielectric barrier discharge plasma processing in an ammonia atmosphere. The NEXAFS studies were p…
This article presents an experimental study on the foaming behavior of recyclable high-melt-strength (HMS) branched polypropylene (PP) with CO 2 as a blowing agent. The foamability of branched HMS PP has been evaluated using a tandem foaming extruder system. The effects of CO 2 and nucleating agent contents on the fin…
The environmental scanning electron microscope (ESEM) represents one of the most exciting breakthroughs in electron microscopy since the invention of the electron microscope. Its ability to observe uncoated and hydrated samples enhances the possibility for investigating the wettability of surfaces at a microscopic lev…
Purpose The paper aims to evaluate the influence of mechanical properties of sewing threads on the seam pucker. Design/methodology/approach The mechanical properties of sewing thread were obtained performing tensile testing research. The seam pucker of lightweight fabric was evaluated after sewing, then after 24 h, af…
The purpose of this review is to re-examine some of the existing knowledge on the ultrastructure of softwood fibres and modelling of the hygroelastic properties of these fibres. The motivation is that the ultrastructure of wood fibres has a strong influence on fibre properties such as stiffness and hygroexpansion. Thi…
Automotive plastic components are often required to withstand impact loadings and dissipate energy in automotive collisions, protecting occupants and pedestrians. The design of plastic components against impact loading is not a trivial engineering task, but still a challenging activity. The optimisation of the impact…
We have quantified two-dimensional dopant profiles in Si with high accuracy using a commercial field emission gun scanning electron microscope with added secondary electron energy-filtering capabilities. Quantification was achieved for dopant concentrations of 2.8×1017–7.5×1019cm−3 with an accuracy of ±8.5%. Using ene…
When a water drop falls onto an oil-water interface, the drop usually rests for some time before merging with the water underneath the interface. We report experiments on this process using water- and oil-based Newtonian liquids and polymer solutions, with an emphasis on the non-Newtonian effects. We deduce that the d…
In this study, we have investigated the effects of grain size on the structural and magnetic properties of La0.8Sr0.2MnO3 powder samples. The Williamson-Hall method was employed on the x-ray peak profile of these powder samples to determine the lattice microstrain. It was found that the microstrain increases by decrea…

Transparent films of Fe-doped indium tin oxide (ITO) were grown at oxygen pressures of 5, 1, 10 -1 , 10 -2 , and 10 -3 Pa on yttria-stabilized zirconia (001) substrates by a pulsed-laser deposition method. We observed X-ray diffraction peaks from (00 h ) planes of In 2 O 3 crystalline phase for the films. The films gr…
X-ray microtomography has been used to investigate the mechanisms responsible for rising crack growth resistance with crack propagation (R curve behaviour) in polygranular nuclear graphite. Tomography can be used to observe changes in the crack shape with propagation, and a side grooved specimen has been developed to…
The performance of the advanced Zr alloys (HANA) for a high burn-up fuel has been evaluated in the out-of-pile and in-pile conditions. The corrosion resistance of the HANA claddings was superior to Zicaloy-4 in a PWR-simulating loop condition. The improved corrosion resistance of the HANA claddings was attributed to t…
