There are relatively few metal–organic framework materials that are robust enough to survive post-synthetic modification of their structures. We present test modifications of Ti-MIL125-NH2 leading towards tuning of the porous and catalytic properties of the material. We also present the first use of a mild amide synth…
We report the fabrication, characterisation (SEM, TEM, XPS and Raman spectroscopy) and electrochemical implementation of a graphene paste electrode. The paste electrodes utilised are constructed by simply mixing graphene with mineral oil (which acts as a binder) prior to loading the resultant paste into a piston-drive…
Hydrogen storage is the crucially missing link to a future hydrogen economy. There have been intense efforts in developing nanostructured adsorbent materials for hydrogen storage during the last decade. Storage at ambient temperature is particularly desirable. New approaches include boron- and nitrogen-substituted car…
Modification of TiO2 with metal oxide nanoclusters such as FeOx, NiOx has been shown to be a promising approach to the design of new photocatalysts with visible light absorption and improved electron–hole separation. To study further the factors that determine the photocatalytic properties of structures of this type,…
We herein report density functional investigations of uranyl adsorption on γ-Al2O3 surfaces. By applying periodic slab models, we report the possible configurations of uranyl adsorbed on the (100) and (110) surfaces of γ-Al2O3 by calculations using density functional theory. The above mentioned two surfaces are expect…
Effective Lennard-Jones models for the water-carbon interaction are derived from existing high-level ab initio calculations of water adsorbed on graphene models. The resulting potential energy well (εCO + 2εCH ≈ 1 kJ mol(-1)) is deeper than most of the previously used values in the literature on water in carbon nanotu…
Aerosol methods, including spray drying and spray pyrolysis, represent industrial scale routes to materials on account of their continuous nature. Recently, these methods have been used to prepare size-, shape- and architecturally controlled nanostructures for a range of inorganic materials. In this Feature Article, a…
Self-assembled ordered mesoporous organic–inorganic hybrid tinphosphonate nanomaterial (HSnP-2) with crystalline framework structure has been synthesized through the reaction of benzene-1,3,5-triphosphonic acid (BTPA) and Sn(IV) chloride under hydrothermal conditions at 453 K in the absence of any structure directing…
Inspired by the exceptional climbing ability of gecko lizards, artificial fibrillar adhesives have been extensively studied over the last decade both experimentally and theoretically. Therefore, a new leap towards practical uses beyond the academic horizon is timely and highly anticipated. To this end, we present a fi…
Solvothermal reaction of a dendritic hexacarboxylic acid with Tb(NO3)3·6H2O afforded a mesoporous lanthanide–organic framework (UTSA-61) whose single-crystal X-ray structure was characterized to have octahedral cages of 2.4 nm in diameter. This mesoporous MOF not only exhibits novel hey topology, but also maintains pe…
Depending on the reference power plant, the type of fuel and the capture method used, the CO 2 product stream contains several impurities which may have a negative impact on pipeline transportation, geological storage and/or Enhanced Oil Recovery (EOR) applications. All negative impacts require setting stringent quali…
Zinc oxide (ZnO) nano-sized particles (NPs) are beneficial materials used for sunscreens and cosmetics. Although ZnO NPs are widely used for cosmetics, the health effects of exposure during pregnancy on offspring are largely unknown. Here we investigated the effects of prenatal exposure to ZnO NPs on the monoaminergic…
Hyperpolarization techniques, such as Overhauser dynamic nuclear polarization (DNP), can provide a dramatic increase in the signal obtained from nuclear magnetic resonance experiments and may therefore enable new applications where sensitivity is a limiting factor. In this contribution, studies of the (1)H and (19)F O…
Monitoring isotopic compositions of gaseous products (e.g., H2, O2, and CO2) by time-resolved isotope-ratio membrane-inlet mass spectrometry (TR-IR-MIMS) is widely used for kinetic and functional analyses in photosynthesis research. In particular, in combination with isotopic labeling, TR-MIMS became an essential and…
Various micro/nanostructured WO3·0.33H2O crystallites were successfully controlled by employing microwave heating under different conditions. By using X-ray diffraction, scanning electron microscopy, transmission electron microscopy and high resolution transmission electron microscopy, the phase and morphology of the…
We demonstrate for the first time that employing a circle chain embracing π-conjugated backbone is a promising strategy to construct superior organic sensitizers for dye-sensitized solar cells (DSCs), with simultaneous improvement of photocurrent and photovoltage. A DSC based on one circle chain embracing dye produced…
Atom transfer radical polymerization (ATRP) of N-acryloylglycinamide has been used as a tool to make poly(NAGA) showing UCST-type phase transitions in water and electrolytes independent of molar mass and end-groups. We hypothesized that similarity in the structure of polymer chain ends with the repeat unit of poly(NAG…
The strain and temperature dependent memory effect of organic memory transistors on plastic substrates has been investigated under ambient conditions. The gold (Au) nanoparticle monolayer was prepared and embedded in an atomic layer deposited aluminum oxide (Al(2)O(3)) as the charge trapping layer. The devices exhibit…
Herein a facile method is developed for fabrication of polystyrene/silver (PS/Ag) composite particles based on colloid thermodynamics. In our system, once the silver nanoparticles are formed in the presence of PS microspheres, they will play the role of steric stabilizer and attach spontaneously onto the surface of PS…
Pharmaceuticals in conjunction with nanoparticle delivery systems are growing towards new heights. The aim of this review is to gain a thorough understanding of different types and characteristics of nanoparticle based delivery systems, important properties of delivery systems, pharmaceutical ingredient loading and re…
