In the present research, seven multi-phase diffusion couples, with terminal alloys having different microstructural features, were prepared and annealed for 4 weeks at 335°C. The phase relations and change of morphological characteristics of each phase were studied along the diffusion zone by means of scanning electro…
Abstract N ‐Benzyl‐ O ‐carboxymethyl chitosan (OCChB) was synthesized through a reaction of O ‐carboxymethylchitosan (OCCh) and benzaldehyde by the reductive amination method. The chemical structures and physical properties of the derivatives were confirmed by Fourier transform infrared spectroscopy and 1 H‐NMR. The c…
In the present work the effect of the HClO4 concentration over the morphology and growth of anodic Ti oxide films in fluoride containing electrolytes is studied. The voltammetric behavior of the Ti is not considerably affected by HClO4 concentration, showing a current plateau in a high potential range in which the ano…
In this study, chemically treated Alcell lignin was used as a compatibilizer in the preparation of polypropylene–oil palm empty fruit bunch (PP-EFB) composites. Basically, this study was divided into two stages. In the first stage, glycidyl methacrylate (GMA) and allyl glycidyl ether (AGE) were used to treat Alcell li…
Abstract In this article, we describe the synthesis of two azobenzene and two stilbene‐based diacetylene chromophores containing terminal electron‐donating (OCH 3 ) and electron‐withdrawing (NO 2 ) terminal groups with esterification reactions. The target compounds were characterized by NMR, X‐ray diffraction (XRD),…
Abstract Biodegradable poly(butylene succinate‐ co ‐butylene adipate) (PBSA)/multiwalled carbon nanotubes (MWCNTs) nanocomposites were prepared via a simple melt‐compounding method at low MWCNTs contents. Scanning and transmission electron microscopy observations revealed a relatively nice dispersion of MWCNTs through…
Abstract The physicomechanical behavior and flammability properties of waste polyethylene and recycled waste rubber powder blend (WPE/RWRP/MA) filled with antimony trioxide (Sb 2 O 3 ), at different contents 5, 10, 15, and 20 wt %, and irradiated with different gamma radiation doses, namely 50, 75, 100, and 150 kGy, w…
The availability of high quality optical fibers with transmission window, larger than that of silica fiber, extends the use of optical fibers and open new application fields. There is increasing demand of optical fiber with transmission over 2 microns, where silica is opaque, for applications as diverse as sensing, fi…
Permafrost-affected palevye (pale) soils of Central Yakutia are developed from mantle calcareous deposits of different textures and are characterized by the common mica-chloritic association of clay minerals with a higher content of chlorite in comparison with the soils developed from mantle loams and loess-like loams…
Abstract A novel polymer‐nanoclay hybrid nanocomposite based on polyvinyl acetate (PVAc)‐organophilic montmorillonite (OMMT) has been reported via an in situ intercalated polymerization technique. The hybrid material was synthesized by one‐step emulsion polymerization of vinyl acetate in the presence of OMMT using pol…
Abstract When polycarbonate (PC)/poly(acrylonitrile–butadiene–styrene) (ABS) blends are exposed to outdoor conditions, they are mainly degraded by sunlight; this is known as photodegradation . It is the ultraviolet radiation in the sunlight that is responsible for the degradation of the blend. To stabilize the blend a…
The translation of the next generation of triggered nanotechnologies in the clinic that are responsive to multiple triggers, both external and internal, may provide cost-effective and efficient ways of improving the efficiency of chemotherapeutic agents."
Layer-by-layer polyelectrolyte films made of the naturally derived polysaccharides chitosan (CHI) and hyaluronic acid (HA) constitute a well-studied system for the development of cell-responsive biointerfaces. However, many cell lines exhibit decreased adhesion to CHI/HA multilayer films, particularly as the number of…
The sonochemical decolorization and degradation of azo dye Methyl violet using Fenton-s reagent in the presence of a high-frequency acoustic field has been investigated. Dyeing and textile effluents are the major sources of azo dyes, and are most troublesome among industrial wastewaters, causing imbalance in the eco-s…
Possible ferromagnetic and ferroelectric orders in ceramic Bi 1– x La x MnO 3 ( x = 0.0, 0.1, and 0.2) samples prepared under 3–6 GPa pressure have been investigated. Rietveld fits to powder neutron diffraction data show that BiMnO 3 and Bi 0.9 La 0.1 MnO 3 adopt a monoclinic C 2/ c perovskite superstructure whereas B…
Abstract In acetone solution, uniform polyaniline (PANI) nanospheres have been successfully synthesized by using cellulose acetate (CA) as a single template, which provides the first example of uniform PANI nanospheres synthesized in nonaqueous system. Our result exhibits that the CA micelle in nonaqueous medium plays…
By means of high-resolution calorimetry, we studied thermodynamic properties of the liquid-crystal B(4) phase where bent-core molecules form a helical nanofilament structure. Distinctive thermal behavior characterizing the growth process of the B(4) phase was obtained in undergoing the phase transition with many sharp…
Abstract It is common for crude oil from wells to be accompanied by gas and water because of the presence of natural surfactants in the oil that stabilize the associated water. This causes foaming during processing in gas/oil separators because of the constant agitation and shear forces, which reduce the efficiency of…
Abstract Application of softeners on fabrics can usually increase the fabric pilling tendency and it is difficult to obtain a soft handle fabric without pilling during wearing. This research was conducted to use various chemicals to reduce pilling with reasonable softness on the cotton/polyester knitted fabric. Divers…
Of the various phases of transition alumina, iota-alumina (\ensuremath{\iota}-Al${}_{2}$O${}_{3}$) is the least well known. It is considered to be the end member of the mullite series in the limit of zero Si content. The structural details of \ensuremath{\iota}-Al${}_{2}$O${}_{3}$ are not available and its physical pr…
