We report synthesis of hollow calcium phosphate (CaP) nanospheres with high surface area by using block copolymer micelles as templates. The obtained CaP nanospheres exhibit very high biocompatibility, showing great promise for intracellular bio-applications in future.
A simple and inexpensive method to form a hematite photoanode for efficient water oxidation is reported. A very thin ZnO overlayer was deposited on top of a thin film of hematite and found, compared with non-treated hematite, to increase the photocurrent and reduce the onset potential for generating oxygen from water.…
Uniformly sized superparamagnetic single-shell nonporous (S1) and double-shell mesoporous silica nanocomposite particles with ∼130 nm magnetite cluster cores are synthesised in this study. Mesoporous particles are prepared with two BJH pore sizes (2.44 and 3.76 nm, designated as S2 and S3 particles, respectively). Onc…
Monodispersed silica-coated ZnO nanoparticles were successfully synthesized and modified with hydrophilic amino groups on the surfaces. The emission colour of the as-prepared ZnO nanoparticles could be tuned by adjusting the reactant ratio and the reaction time. The resulting particles were stable in water, phosphate…
Efficient luminescence was realized by suppressing not only excited-state distortion but also C-H vibrational quenching in a Cu complex. Organic light-emitting diodes containing the Cu complex as an emitting dopant exhibited a maximum external quantum efficiency of 7.4%.
CdSe and CdSe/CdS quantum dots (QDs) with narrow size distribution are attached onto TiO2 electrodes by linker-assisted chemical bath deposition (LACBD). Preparation is carried out at 60 °C or 160 °C, which results in the formation of CdSe or CdSe/CdS QDs onto the TiO2 nanoparticles connected by thioglycolic acid (TGA…
The new Al-based metal-organic framework [Al(13)(OH)(27)(H(2)O)(6)(BDC-NH(2))(3)Cl(6)(C(3)H(7)OH)(6)] denoted CAU-6 (CAU = Christian-Albrechts-Universität) was solvothermally synthesized in 2-propanol and was thoroughly characterized. The framework structure exhibits a unique column-shaped inorganic building unit, whi…
A diverse set of imidazole- and π-expanded imidazole derivatives displaying excited state intramolecular proton transfer (ESIPT) was designed and synthesized. The effect of structural variation on photophysical properties was studied in detail for nine dyes. The relationship between the structure and photophysical pro…
A bifunctional visible-light photocatalyst Ag–AgBr/TiO2 was synthesized by a facile one-pot method. The three-component composite exhibited much superior visible-light photocatalytic activities for ibuprofen (IBP) degradation and mineralization as compared to single-component (TiO2) and two-component (Ag/TiO2, Ag–AgBr…
Amorphous FeVO4 nanosheet arrays have been grown directly from a flexible stainless steel (SS) substrate by a facile template-free and catalyst-free chemical vapour deposition (CVD) method. These FeVO4 nanosheets showed superior Li storage properties, especially at high current densities.
With the verification of the existence of the dissolution–electrodeposition mechanism during the electro-reduction of solid silica in molten CaCl2, the present study not only provides direct scientific support for the controllable electrolytic extraction of nanostructured silicon in molten salts but it also opens an a…
Lithium/sulfur (Li/S) battery is unique in that it is indeed a liquid electrochemical system. In discharge, elemental sulfur is first reduced into high order polysulfide (PS, Li 2 S x , x = 8), which dissolves into liquid electrolyte and leaves voids in the cathode, whereas in the last stage, the dissolved low order P…
Ionic liquids have been shown to be highly effective lubricants for a steel on aluminium system. This work shows that the chemistry of the anion and cation are critical in achieving maximum wear protection. The performance of the ILs containing a diphenylphosphate (DPP) anion all showed low wear, as did some of the tr…
Cerium-doped titanium oxide (Ce–TiO2) nanoparticles were prepared by a simple sol–gel method. Ce-doping decreased the crystal size of TiO2, increased the catalyst surface area, and inhibited the growth of rutile TiO2 crystals. Ce–TiO2 nanoparticles were also dispersed on SBA-15, mesoporous silica with one-dimensional…
A novel, simple approach to the synthesis of macrocyclic Schiff base ligand resulted from the condensation of bisaldehyde and ethylenediamine was prepared (7, 8, 15, 16, 17, 18-hexahydrodibenzo (a, g) (14) annulene) (L) and its complexes were synthesized and characterized using different physicochemical studies as ele…
This paper discusses various interactions between ultrasound, phospholipid monolayer-coated gas bubbles, phospholipid bilayer vesicles, and cells. The paper begins with a review of microbubble physics models, developed to describe microbubble dynamic behavior in the presence of ultrasound, and follows this with a disc…
Herein, we report a facile approach to decorate graphene oxide (GO) sheets with poly(vinyl acetate) (PVAc) by γ-ray irradiation-induced graft polymerization. The content of PVAc in the obtained sample, i.e., PVAc grafted GO (GO-g-PVAc) is calculated by the loss weight in thermogravimetric analysis (TGA) curves. A GO-g…
This Feature Article gives an account for a host of readily available foldamers and macrocycles with well-defined shapes and non-deformable cavities that appeared over the last decade. Efforts to create porous molecular structures have led to the establishment of an effective strategy for enforcing the folding of unna…
A new strategy of molecular imprinting to prepare spherical hydrogels via water-in-oil Pickering emulsion polymerization was developed. The imprinted hydrogels exhibited fast adsorption kinetics and significant selectivity for the target protein.
Three new metal-organic frameworks (MOFs) are designed by the assembly of flexible V-shaped ligands and paddle-wheel second building units (SBUs). The topology, interpenetration numbers and porosity of frameworks have been well controlled by a solvent system.
