Abstract This paper provided an easy and flexible method to synthesize high molecular weight polyesters by polycondensation and chain extension. Low molecular weight polybutylene adipate, polybutylene succinate, and poly(butylene succinate‐co‐butylene adipate) (PBSA) were synthesized through melt condensation polymeri…
Abstract A boron‐modified ethynylhydridopolycarbosilane (B‐EHPCS) was successfully prepared via the hydroboration reaction of ethynylhydridopolycarbosilane (EHPCS) with 9‐borabicyclo‐[3.3.1]nonane (9‐BBN). The as‐synthesized B‐EHPCS with a branched structure was characterized by means of gel permeation chromatography…
This study focuses on investigating the effects of conventional calcination procedures and O 2 plasma treatments on the metal precursor−support interaction (MPSI) of 1 wt % Pd/TiO 2 . MPSI is likely a strong precursor to the metal−support interaction of supported metal catalysts. The authors identify H 2 -DSC (H 2 -di…
Electronic and magnetic structures of the recently synthesized cobalt oxyselenide ${\text{La}}_{2}{\text{Co}}_{2}{\text{Se}}_{2}{\text{O}}_{3}$ (structurally similar to the superconducting iron pnictides) are studied through density-functional calculations. The obtained results show that this material is a Mott insula…
Abstract The poly(phenylsilsesquioxane) (PPSQ) particles were prepared with both basic and acidic catalyzed processes and the PP/PPSQ composites were prepared by melt blending method. Studies on PPSQ by Infrared (IR), X‐ray diffraction (XRD), 29Si cross polarized (CP) nuclear magnetic resonance (NMR) spectroscopy show…
Scanning tunneling spectroscopies are performed below 100 mK on polycrystalline boron-doped diamond films characterized by transmission electron microscopy and transport measurements. We demonstrate a strong correlation between the local superconductivity strength and the granular structure of the films. The study of…
A Gd(2)O(3):Eu nanocrystal phosphor has been directly synthesized by a mild solution combustion method with a single step approach while avoiding further thermal annealing. The as-combusted Gd(2)O(3):Eu powders have been characterized by x-ray diffraction, infrared spectroscopy, transmission electron microscopy and ph…
The author has been involved in corrosion prevention and control for Australian Defence Force (ADF, Canberra, Australia) aircraft and helicopters for more than 40 years. During those years, polymeric and conversion coatings and plated metallic layers have been the major technologies used for preventing corrosion. Chro…
The optical bright- and dark-field visualization (see image) of single-walled carbon nanotubes spin-casted onto Si/SiO2 substrates with a 300-nm-thick oxide coating is reported. This novel procedure gives access to a low-cost correlation of Raman spectroscopy with microscopic techniques (atomic force microscopy, scann…
Abstract Bubble‐electrospinning is suggested to produce micro/nano fibers. Contrary to classical electrospinning where a high voltage is applied to overcome the surface tension of the Taylor's cone, in bubble‐electrospinning, the voltage is applied to overcome the bubble's surface tension, which mainly depends upon th…
Novel T-shaped ZnS nanostructures are synthesized through simple ZnS powder evaporation. High-resolution transmission electron microscopy (HRTEM) and electron diffraction (ED) analyses demonstrate that the structures are composed of a bicrystalline base sheet (010)/(102)/(010)* and a protruding thick wire. The two str…
The solvent extraction of 12-phosphotungstic acid, also known as 12-tungstophosphoric acid—H3PW12O40, the so-called Keggin heteropolyacid—by 0.73 M (20%v/v) tri-n-butyl phosphate (TBP) in n-octane under conditions comparable to those used previously for the extraction of conventional inorganic mineral acids is describ…
Abstract Flame retardancy of bisphenol A polycarbonate (PC)/poly(butylene terephthalate) (PBT) blends was improved by the addition of resorcinol bis(diphenyl phosphate) (RDP) and poly(phenylene ether) (PPO). A PC/PBT blend at 70/30 weight ratio obtained a V‐0 rating by the addition of 10 wt% RDP and 10 wt% PPO. The co…
The magnetic structure of multiferroic ${\text{Ni}}_{3}{\text{V}}_{2}{\text{O}}_{8}$ has been investigated using nonresonant x-ray magnetic scattering. Incident circularly polarized x rays combined with full polarization analysis of the scattered beam is shown to yield high sensitivity to the components of the cycloid…
Abstract Blends of polypropylene (PP) and epoxidized natural rubber (ENR) were prepared by an in‐line electron induced reactive processing technique. The mixing was done in a Brabender mixing chamber coupled with an electron accelerator. The effect of sequence of electron treatment on the compatibilization of non‐pola…
We have systematically investigated the doping and the directional dependence of the gap structure in the 122-type iron pnictide superconductors by point contact Andreev reflection spectroscopy. The studies were performed on single crystals of ${\text{Ba}}_{1\ensuremath{-}x}{\text{K}}_{x}{\text{Fe}}_{2}{\text{As}}_{2}…
Abstract Corrosion behaviour of the new TiMo alloys together with the currently used metallic biomaterials commercial pure titanium (Cp‐Ti) was investigated for dental applications. Ingots of composition Ti12Mo, Ti20Mo and Ti40Mo were synthesized by the cold crucible levitation melting (CCLM) technique. All the sample…
Abstract The potential of using dispersive domains in a polymer blend as a bubble nucleating agent was investigated by exploiting its high dispersibility in a matrix polymer in the molten state and its immiscibility in the solid state. In this experiments, polypropylene (PP) was used as the nucleating agent in polysty…
Abstract Caustic embrittlement, a kind of stress corrosion cracking (SCC), is always encountered on materials under stresses amid caustic environment. Acidic corrosion is another familiar degradation on materials contacting acidic media. However, it has been seldom studied what effect would be resulted in on materials…
Hygiene is a permanent concern for food industries since they must commercialize high quality products in order to comply with the legislation and the expectations of the consumers. The hygienic state of a surface is thus a critical parameter with respect to the performances of the production process and to the final…
