Increasing demand for energy requirement has attracted considerable attention among researchers to develop efficient energy storage device. Among energy storage devices, electrochemical capacitor (EC) has great potential for its capability to deliver more power than batteries and store more energy than conventional ca…
The elastic and optical properties of a bent-core thiadiazole nematic liquid crystal are reported. The system exhibits unusually large values of birefringence (∼0.4), which can be partly attributed to significant conjugation in the molecular structure. It is found that the splay (K11), twist (K22) and bend (K33) elast…
A novel surface modification strategy for an electrospun nanofibrous film was reported, allowing detection and removal of copper ions in the aqueous solution. This reusable dual fluorescent-colorimetric nanofibrous film can be utilized conveniently to achieve real-time naked-eye sensing in aqueous medium just like usi…
Abstract—The asymmetric transmission of the linearly polarized waves at normal incidence through the lossy anisotropic chiral structure is demonstrated. The proposed chiral metamaterial structure is composed of bi-layered discontinuous cross-wire-strips, and it is utilized in order to realize polarization rotation. Fi…
A bis(permethylated β-cyclodextrin)-substituted aza-BODIPY has been prepared, which forms stable 1 : 1 host-guest complexes with metal-free and zinc(II) tetrasulfonated porphyrins in water. The resulting complexes exhibit predominantly a photoinduced energy or electron transfer process depending on the porphyrin-based…
The control of surface properties such as the morphology, roughness, stiffness, and wettability of polyelectrolyte multilayers was carried out using poly(diallyldimethylammonium chloride) (PDADMAC) and poly(4-styrenesulfonic acid-co-maleic acid, 1 : 1 SS : MA) sodium salt (PSSMA 1 : 1) as the building blocks via adjus…
The crystallographic analysis of the title compound shows that there are two crystallographically independent molecules in a unit cell. The magnetic study clarified that every molecule behaved as a single-molecule magnet. Two series of the out-of-phase ac susceptibility signals appeared around 10 K even at zero dc fie…
Graphene sheets with an adjustable number of layers and a low defect density were prepared by exfoliation of microwave-assisted expanded graphite in the aqueous phase with the assistance of cetyltrimethylammonium bromide. The graphene sheets exhibit excellent film-formation ability, showing potential applications in o…
The computational methods for the diffraction integrals that occur in the Extended Nijboer-Zernike (ENZ-) approach to circular, aberrated, defocused optical systems are reviewed and updated. In the ENZ-approach, the Debye approximation of Rayleigh’s integral for the through-focus, complex, point-spread function is eva…
Two new polyoxometalate (POM)-based metal-organic frameworks (MOFs) constructed from multinuclear silver-ptz cycle/belts, namely [Ag7(ptz)4(NO3)(H2O)][H4P2W18O62]·5H2O () and [Ag6(ptz)4(H2O)2][HPMo12O40]·3H2O () (ptzH = 5-(3-pyridyl)-1H-tetrazole), have been successfully synthesized under hydrothermal conditions via c…
Phenobarbital was investigated as corrosion inhibitor for mild steel in 1 M HCl solution by weight loss and quantum chemical calculations. Phenobarbital showed 95 % inhibition efficiency at concentration of 200 ppm. The adsorption of the inhibitor followed Langmuir adsorption isotherm. The quantum chemical calculation…
The influence of oxidized starch on the physicochemical properties of cast soy protein isolate films is determined in this study.Films were cast from heated (70 °C for 20 min) alkaline (pH=10) aqueous solutions of 7 % soy protein isolate containing 50 % (by mass) glycerol as a plasticizer and different levels of added…
α-MnO2 hollow-sphere-like clusters composed of nanotubes have been synthesized on a large scale by a simple hydrothermal method. The results show that the 3D hollow-sphere-like clusters are assembled by 1D nanotubes (HSC-nanotubes) with diameter of around 80–100 nm and length of around 2–3 μm. The influences of reacti…
A series of novel Ce3+ singly doped and Ce3+/Mn2+ co-doped color-tunable KBaY(BO3)2 phosphors were synthesized by a high-temperature solid-state reaction, and the crystal structures and luminescence properties were investigated in detail. The crystallographic cation sites occupancy of the doping Ce3+ and Mn2+ ions for…
The weak intramolecular F∙∙∙N and S∙∙∙N interactions in the novel pyridine-containing perfluorodiarylethenes achieved high cyclization quantum yields in solutions. While the F∙∙∙N interactions stabilize the photoreactive conformation, the S∙∙∙N contacts contribute from the energetic aspect.
Nowadays the world has experiencing global warming due to excessive energy release into atmospheres. Today, a lot of research being conducted on ways to recover or reused the energy losses. An experimental investigation has been carried out to identify the most suitable cooling system techniques to achieve a stable an…
Hybrids consisting of graphene oxide (GO) sheets and butadiene-styrene-vinyl pyridine rubber (VPR) were prepared by a co-coagulation process with different flocculants, hydrogen chloride and calcium chloride, in order to form two kinds of bonding interfaces, namely ionic bonding (HVPR) and hydrogen bonding (CaVPR) int…
A comprehensive in situ analysis of the formation of graphene during the thermal exfoliation via reduction expansion synthesis (RES) of graphite oxide (GO) in the presence of urea is presented. The addition of urea expedites the exfoliation and reduction process while introducing nitrogen (N) impurities, which serve a…
A novel diphenoxo-bridged Gd(3+)-Mn(2+) dimer is proposed as a good candidate for cryogenic magnetic refrigeration. The large MCE is enhanced by the ferromagnetic interaction between the two metal ions.
A chiral dithienylperfluorocyclopentene molecule bearing two bridged binaphthyl units was designed and synthesized by a Suzuki–Miyaura cross-coupling reaction between chiral binaphthyl iodide and dithienylperfluorocyclopentene-derived bis(boronic ester). Its photoresponsive properties were investigated in both organic…
