The refined x-ray crystal structure of the phase Mg(27)Al(10.7(2))Zn(47.3(2)) (Pa3) establishes it as the new 2/1 Bergman-type approximant of the icosahedral quasicrystal. The primitive cubic lattice consists of condensed triacontahedral and novel prolate rhombohedral (PR) clusters. Each triacontahedron encapsulates t…
Purpose Aims to investigate the inhibitive effect of the new series of Schiff base molecules, namely, N, N′‐ethylen‐bis(salicylidenimine) [S1], N, N′‐isopropylen‐bis(salicylidenimine) [S2] and N, N′‐Ortho‐phenylen acetyl acetone imine, (2‐hydroxy Benzophenone imine) [S3] on corrosion of copper during acid pickling tre…
A convenient preparation is reported for subnanometre size uncapped ZnO quantum dots, which permits the previously inaccessible live observation of the growth of the clusters in the molecular size regime. The preparation method utilizes electric field-induced transient pore formation (electroporation) in synthetic uni…
Tantalum liners have been successfully bonded to the inside surface of an M242 Bushmaster barrel using a low-detonation velocity explosive. This report examines the governing equations of the explosive bonding process as they apply to this particular situation. The relevant properties of other high-strength tantalum a…
In this and the following companion articles, the authors present the 2ω method, a novel ac mode local thermal property imaging technique with nanoscale spatial resolution. To demonstrate the use of the thermoelectric probe as an active one that can function as both a heater and a temperature sensor, the authors devel…
Abstract The attenuation of heavy metals in ground water depends on factors such as solid‐solution equilibrium or the solubility product ( K sp ) of the solid phase. Metals are pH dependent, and the solubility of heavy metal hydroxides such as lead, cadmium, zinc, and nickel is minimal within pH range 9 to 11. MgO as…
Abstract As‐grown (100) homoepitaxial diamond films with boron concentrations [B] from 4.6 × 10 16 to 1.5 × 10 21 cm –3 have been analysed using X‐ray photoelectron spectroscopy (XPS). Their C 1s core levels contain a dominant component around 284.17 ± 0.2 eV ascribed to sp 3 C and a main secondary component around 28…
To study the structure-function relationship of the oxidative-damage effect of ascorbic acid, we have focused on the interaction between plasmid DNA pUC19 and a series of ascorbic acid derivatives modified on different OH groups in the presence of transition metal ions. Some ascorbic acid derivatives can selectively c…
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…

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…
