An acid-assisted ultrarapid thermal strategy is developed for constructing specifically functionalized graphene. The electrochemical performance of functionalized graphene can be boosted via elaborate coupling between the pseudocapacitance and the electronic double layer capacitance through rationally tailoring the st…
Microbially influenced iron corrosion by sulfate-reducing bacteria (SRB) is conventionally attributed to the chemical corrosiveness of H2S, facilitated abiotic H+-reduction at deposited FeS, and biological consumption of chemically formed (‘cathodic’) H2. However, recent studies with corrosive SRB indicated direct con…
We report single-atom doping of gold nanoclusters (NCs), and its drastic effects on the optical, electronic, and catalytic properties, using the 25-atom system as a model. In our synthetic approach, a mixture of Pt(1)Au(24)(SC(2)H(4)Ph)(18) and Au(25)(SC(2)H(4)Ph)(18) was produced via a size-focusing process, and then…
The chiroptical properties of pure inorganic material are reported by Shunai Che and co-workers on page 3784. The properties are investigated by dispersing achiral metal nanoparticles into chiral mesoporous silica, due to collectively asymmetric plasmon interactions of metal nanoparticles arranged along a helical pore…
Oriental Journal of Chemistry is a peer reviewed quarterly research journal of pure and applied chemistry. It publishes standard research papers in almost all thrust areas of current chemistry of academic and commercial importance. It provides a platform for rapid publication of quality research papers, reviews and ch…
There are quite There are quite a few defects can occur due to manufacturing of the composites such as voids, resin-rich zones, pockets of undispersed cross-linker, misaligned fibres and regions where resin has poorly wetted the fibres. Such defect can reduce the mechanical properties as well mechanical performance of…
Positive temperature coefficient of resistivity (PTCR) ceramics of 0.912( Ba 1+ x TiO 3 )–0.088( Bi 0.5 Na 0.5 TiO 3 ) ( BT – BNT ) ( x = − 0.03 to 0.03) were prepared using the mixed oxide route and sintered at 1340°C for 4 h. Products were predominantly single phase with a tetragonal structure and grains in 2–6 μm s…
Abstract The molecular dynamics of liquid‐crystalline polymethacrylates with biphenyl in the side group forming a highly ordered smectic E phase at low temperatures is investigated by dielectric spectroscopy (DS). Although no glass transition is found by DSC, DS detects a relaxation in the smectic E phase resembling t…
An experimental investigation of high velocity impact responses of composite laminated plates using a helium gas gun has been presented in this paper. The aim of this study was to develop the novel composite structure that meets the specific requirements of ballistic resistance which used for body protections, vehicle…
Quarantine treatments of raw cotton fiber with gamma irradiation are known to have an adverse effect on fiber properties and thus could have an effect on processing into textile products. In this study, the effects of such irradiation treatments on two different cottons, cultivars of Upland and Extra Long Staple, were…
The bending rigidity of laminated fabric was investigated considering the positions of the neutral axes in bending for components in addition to the tensile and in-plane compressive moduli of components. Theoretically derived equations were proposed to obtain the position of the neutral axis and to predict bending rig…
Abstract Thin layers of the thermo sensitive cross‐linked poly( N ‐isopropylacrylamide) gel were anchored on the surface of platinum micro‐ and regular‐electrodes. No preliminary functionalization of the surface was used; just electroformation of radicals at the surface led to strong binding of the polymer net. The el…
Spherical CuS nanocrystals were synthesised via reflux (R) and hydrothermal (H) methods using copper acetate monohydrate (Cu (ac)2·H2O) and thioacetamide as precursors. This process was carried out in the absence and presence of cetyltrimethylammonium bromide (CTAB) and sodium dodecyl sulphate (SDS) surfactants. The p…
Three perylenetetracarboxylic diimide (PDI) derivatives consisting of a short oligo(L-lactic acid)(n) (O-LLA) segment at one imide nitrogen were synthesized. The polymers were characterized by (1)H NMR and gel permeation chromatography (GPC). Their properties were investigated by differential scanning calorimetry (DSC…

The petroleum industry and desalination plants suffer from marine bio-fouling problems that have a major role in the stimulation of the corrosion process. Thus, the aim of this study was to investigate the effect of the micro and the macro-organisms, on the corrosion behavior of different alloys used in Kuwait’s indus…
A diffractive optical element is fabricated with relative ease in a glass containing spherical silver nanoparticles 30 to 40 nm in diameter and embedded in a surface layer of thickness ~10 μm. The nanocomposite was sandwiched between a mesh metallic electrode with a lattice constant 2 μm, facing the nanoparticle conta…
Azobenzene polymers have been the subject of intensive research due to their unique and unexpected properties that allow various applications triggered by light. One of their attractive features is the possibility of changing the orientation of azobenzene chain through trans-cis-trans photoisomerization cycles to phot…
Abstract The structure of Ru 2 B 3 [space group P 6 3 / mmc , no. 194, a = 290.489(1) pm, c = 1281.637(6) pm] and Os 2 B 3 [space group P 6 3 / mmc , no. 194, a = 291.451(2) pm, c = 1292.13(1) pm] were determined using neutron diffraction and 11 B‐isotopically enriched crystalline powder samples. Thus it was possible…
Fractionated crystallization (FC), a chain-sorting mechanism by length, is identified in well-defined, low molecular weight, and defect-free regioregular poly(3-hexylthiophene) by X-ray scattering and calorimetry of bulk samples. While wide-angle X-ray scattering (WAXS) qualitatively suggests that the degree of crysta…
