Quantum-sized SnO2 nanocrystals can be well dispersed on reduced graphene oxide (rGO) nanosheets through a convenient one-pot in situ reduction route without using any other chemical reagent or source. Highly reactive metastable tin oxide (SnO(x)) nanoparticles (NPs) were used as reducing agents and composite precurso…
Organic donor–acceptor dyes, formed by a high-yielding [2 + 2] cycloaddition–retroelectrocyclisation process between aniline-substituted alkynes and tetracyanoethylene (TCNE) or 7,7,8,8-tetracyanoquinodimethane (TCNQ), were employed as novel photosensitizers without carboxylic acid anchoring groups in dye-sensitized s…
We present for the first time, the solid state phase behaviour of the organic ionic plastic crystal (OIPC) N -methyl- N -ethyl-pyrrolidinium bis(trifluoromethanesulfonyl)amide, [C 2 mpyr][NTf 2 ], upon mixing with the sodium salt, Na[NTf 2 ].
Salinity-gradient energy can be recovered (68% efficiency) with a mixing entropy battery alternately flushed with wastewater effluent and seawater.
. These multifunctional fluorescent magnetic nanoparticles have been conjugated with the hydrophobic drug, camptothecin, and a molecular marker, folic acid, using appropriate surface chemistry. The drug-conjugated hybrid nanoparticles inhibit cell growth through the induction of apoptosis as demonstrated in HeLa cells.
Chemical reactions induced by mechanical treatment may give access to new compounds whose properties are governed by chemical metastability, defects introduced and the size effects present. Their interplay may lead to nanocrystalline ceramics with enhanced transport properties being useful to act as solid electrolytes…
A series of novel hole transport materials for organic light-emitting diodes (OLEDs) based on 9,14-diphenyl-9,14-dihydrodibenzo[ a , c ]phenazine were synthesized and characterized by 1 H NMR and 13 C NMR, mass spectrometry and single crystal structure analysis methodologies.
Transition metal complexes, typically Ru-based complexes, are the most efficient dyes used in dye-sensitized solar cells. The absorption spectra of these molecules generally involve numerous electronic transitions, which are not equivalent for the conversion of the light into electricity. In the present manuscript, an…
A facile and straightforward method has been developed to synthesize laminated-structured Fe3O4/graphene composite through solvothermal reaction. The particle size and coverage density of Fe3O4 on graphene sheets were controlled by adjusting the molar ratio of graphite oxide (GO) and Fe (II) ions. Spherical Fe3O4 nano…
The expansion of batteries into electric vehicle and grid storage applications has driven the development of new battery materials and chemistries, such as olivine phosphate cathodes and sodium-ion batteries. Here we present atomistic simulations of the surfaces of olivine-structured NaFePO4 as a sodium-ion battery ca…
This paper reports the defect-induced band gap narrowing of pure SnO 2 nanostructures (p-SnO 2 ) using an electrochemically active biofilm (EAB).
We built a model of charge transport in a single disordered polymer chain starting from a model Hamiltonian of the system. The parameters entering the Hamiltonian determine both the density of states (DOS) and the hopping rate unlike the most common modelling strategies of transport in polymeric materials that paramet…
Thermal plasmas and lasers are used in medicine to cut and ablate tissues and for coagulation. Non-equilibrium atmospheric pressure plasma (NEAPP) is a recently developed, non-thermal technique with possible biomedical applications. Although NEAPP reportedly generates reactive oxygen/nitrogen species, electrons, posit…
The high cost of noble metal nanoparticles used for catalytic reduction of 4-nitrophenol (4-NP) leads to an extensive study of Ni nanoparticles (NPs) for their low cost and magnetic properties. However, the conventional routes for preparing the ferromagnetic Ni NPs usually lead to large particle size and aggregation.…
A naphthalimide-naphthyridine derivative has been synthesized for the detection of hydroxyl radicals. It can distinguish hydroxyl radicals from other reactive oxygen species with high selectivity and short response time. Moreover, it has no cellular toxicity, and can be effectively used for intracellular detection of…
In this study, sea-urchin shaped Bi2S3/CdS hierarchical heterostructures are successfully synthesized via a convenient one-pot growth rate controlled route. The product is mainly composed of Bi2S3 nanorods and CdS nanoparticles grown on their surfaces. The formation mechanism was proposed based on the evolution of mor…
Titania modified nanoparticles have been prepared by the photodeposition method employing platinum particles on the commercially available titanium dioxide (Hombikat UV 100). The properties of the prepared photocatalysts were investigated by means of the Fourier transform infrared spectroscopy (FTIR), X-ray diffractio…
Hierarchical porous crystalline metal-organic framework (MOF) monoliths are prepared by powder-packing synthesis. The resulting MOF monolithic column shows fast and efficient chromatographic separation.
Designing an efficient catalyst is essential to improve the electrochemical performance for Li–O2 batteries. In this study, the novel composites of Fe/Fe3C carbon nanofibers (Fe/Fe3C–CNFs) were synthesized via a facile electrospinning method and used as cathode catalysts for Li–O2 batteries. Owing to their favorable s…
A novel tunnel Na(0.61)Ti(0.48)Mn(0.52)O2 material is explored as a cathode for sodium-ion batteries for the first time. It can deliver a reversible discharge capacity of 86 mA h g(-1) with an average voltage of 2.9 V at 0.2 C rate in a sodium half cell, exhibiting good rate capability and capacity retention at a cut-…
