NiMnO3-nitrogen doped graphene composite has been synthesized by a simple hydrothermal method and its supercapacitor performance investigated. The composite exhibits a specific capacitance of 750.2 F g(-1) in 1 M Na2SO4 at a scan rate of 1 mV s(-1). Nitrogen insertion inside the carbon lattice plays a crucial role in…
Fe3O4 nanoparticles were first prepared by a facile oxidation–reduction method and then Fe3O4–polyaniline nanoparticles were obtained by an in situ polymerization of aniline in the presence of dodecyl benzenesulfonic acid. The microstructure and electromagnetic properties of the Fe3O4–polyaniline nanoparticles have be…
The title heterobridge system exhibits the coexistence of AF ordering, SCM-derived multi-relaxation dynamics, field-induced metamagnetism and field-induced spin-glass-like dynamics.
This work demonstrates that metallic nanoparticles (NPs) embedded in rare-earth (RE) co-doped dielectrics are able to produce an effect analogous to a reduction in the effective concentration of the luminescent RE ions in the matrix, herein coined the "plasmonic diluent" effect. This has been revealed explicitly for D…
In this study, we have fabricated well-defined silver nanowires by an ultraviolet (UV) irradiation technique in the presence of phosphomolybdic acid (PMo), which acted as a catalyst and stabilizing agent. The effect of fabrication parameters on the morphology of silver nanowires, such as initial concentrations of reac…
Frustration in chain packing has been proposed to play an important role in thermodynamic and dynamic properties of polymeric melts and glasses. Based on a quantitative analysis using Voronoi tessellations and large scale molecular dynamics simulations of flexible and semi-flexible polymers, we demonstrate that the ri…
Here, we studied the self-assembly of two peptide amphiphiles, C16-Gly-Gly-Gly-Arg-Gly-Asp (PA 1: C16-GGG-RGD) and C16-Gly-Gly-Gly-Arg-Gly-Asp-Ser (PA 2: C16-GGG-RGDS). We showed that PA 1 and PA 2 self-assemble into nanotapes with an internal bilayer structure. C16 chains were highly interdigitated within the nanotap…
Graphene has been proposed as a promising transparent conducting electrode material in organic photovoltaic (OPV) solar cells to substitute the widely used indium tin oxide (ITO). Various studies have reported OPV devices with graphene electrodes showing comparable performances to ITO-based OPV cells. However, the fab…
The adsorption of hydrogen-bonded and stacked nucleobase pairs on the hexagonal boron nitride (h-BN) surface was studied by density functional theory and molecular dynamics methods. Eight types of nucleobase pairs (i.e., GG, AA, TT, CC, UU, AT, GC, and AU) were chosen as the adsorbates. The adsorption configurations,…
Dual-modality imaging, using Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET) simultaneously, is a powerful tool to gain valuable information correlating structure with function in biomedicine. The advantage of this dual approach is that the strengths of one modality can balance the weaknesses o…
A novel 2-D coordination polymer constructed from high nuclearity nanosized Ho48 clusters was synthesised and structurally characterized using single-crystal X-ray analysis. The Ho48 cluster core with a charming waist drum-like structure was templated by CO3(2-) ions, and bridged by Ho-N bonds to get a 2-D coordinatio…
Herein we report the self-assembly of a supramolecular singlet oxygen photosensitizing system from an adamantane-functionalized, hexaanionic water-soluble zinc(II) phthalocyanine (PC) and β-cyclodextrin vesicles (CDV). Characterisation of the designed PC, which was synthesized by an asymmetric statistical condensation…
Gold nanoclusters (AuNCs) protected by bovine serum albumin (BSA) can emit red photoluminescence under illumination by ultraviolet light. The luminescence of the BSA–AuNCs was quenched when Cu2+ chelated with glycine in the BSA chain and generated BSA–AuNCs–Cu2+, while the luminescence of the BSA–AuNCs restored when p…
Amorphous MnO2 supported on carbon nanotubes were prepared using a co-precipitation method at room temperature and firstly used for the selective catalytic reduction of NO with NH3. The catalysts showed superior low temperature activity than that of the catalyst prepared using the conventional wet impregnation method.
Surface-enhanced Raman scattering (SERS) is ideally suited for probing and mapping surface species and incipient phases on fuel cell electrodes because of its high sensitivity and surface-selectivity, potentially offering insights into the mechanisms of chemical and energy transformation processes. In particular, bime…
Biodegradable polymers, such as poly(l-lactide) (PLLA), are very useful in many biomedical applications. However, their degradation by-products have been much of a concern as they are the sources of inflammatory reactions in the body. In this work, we suggest a novel composite system composed of PLLA and oligolactide-…
In this communication, we present the colloidal preparation of ternary CuGaS2 (CGS) nanocrystals that exhibit elongated morphologies and possess the metastable wurtzite crystal structure. A facile noninjection-based synthetic strategy was utilized wherein dithiocarbamate complexes of copper and gallium were thermally…
Three derivatives of doxorubicin (DOX) were prepared by modifying DOX with succinic anhydride, cis-aconitic anhydride and 2,3-dimethylmaleic anhydride, generating acid-insensitive succinyl-DOX (SAD), acid-sensitive cis-aconityl-DOX (CAD) and 2,3-dimethylmaleyl-DOX (DAD) respectively. The pH and reduction dual-responsi…
In this study, the use of PE and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) blend films for packaging was investigated by evaluating the performance of the plastic blend and its recyclability. It was found that mechanical properties (tensile strength, elongation at break and Young's modulus) of PE/PHBV blend…
The clay-reinforced epoxy nanocomposite was prepared by the polymerization method. The effect of clay addition on the mechanical properties of epoxy/clay nanocomposites was studied through tensile, flexural, impact strength, and fracture toughness tests. The morphology and tribology behavior of epoxy/clay nanocomposit…
