A divergence from the conventional approach to chromophore design has led to the establishment of many exciting new benchmarks for the dye-sensitized solar cell (DSSC), including the first documented power conversion efficiency in excess of 12% at 1 sun illumination [Yella et al., Science 2011, 334, 629]. Paramount to…
Hollow/flower-like BiOI microspheres have been prepared through a facile precipitation route in a water–ethanol mixed solution with the assistance of PVP and citric acid (CA) at low temperature (70 °C). The obtained products were characterized by a range of methods such as XRD, FESEM, TEM, UV-vis, DRS, PL and nitrogen…
A facile and green process was developed for the synthesis of MoS2 nanospheres by an L-cysteine-assisted hydrothermal method. These MoS2 nanospheres exhibited high specific capacity and good cycle stability because of efficient lithium ion diffusion and the accommodation of mechanical stress owing to their unique stru…
Two series of fac-tris-cyclometalated iridium(III) complexes, series 1 from the 2-(carbazol-3′-yl)-pyridine ligands, and series 2 from the isomeric 2-(carbazol-2′-yl)-pyridine ligands, have been characterised. The photoluminescence and electroluminescence from series 2 complexes are red shifted compared to series 1 co…
Monodisperse TiO2 hollow spheres assembled by nanospindles were prepared via the facile hydrothermal reaction of peroxotitanium complex precursors. Time dependent trails revealed that the shape evolution involved a one-step chemical conversion from amorphous Ti complex microspheres to anatase TiO2 hierarchical hollow…
We report a smart therapeutic nanoplatform based on Fe(3)O(4)@CaP capped gold nanocages, which integrates magnetic targeting, photothermal therapy and chemotherapy for killing cancer cells. Combining photothermal- and chemo-therapy results in a synergistic effect in cancer treatment.
Here we report the successful growth of highly crystalline homogeneous MOF thin films of HKUST-1 and ZIF-8 on mesoporous silica foam, by employing a layer-by-layer (LBL) method. The ability to control and direct the growth of MOF thin films on confined surfaces, using the stepwise LBL method, paves the way for new pro…
A series of new 6-methoxy-2-oxo-1,2-dihydroquinoline-3-carbaldehyde 4N-substituted thiosemicarbazone ligands (H2L1–H2L5) and their corresponding palladium(II) complexes [Pd(L1)(PPh3)] (1), [Pd(L2)(PPh3)] (2), [Pd(HL3)(PPh3)]Cl (3), [Pd(L4)(PPh3)] (4) and [Pd(L5)(PPh3)] (5), have been synthesized in order to evaluate t…
The dehydration of bio-based 2,3-butanediol provides an alternative green way to produce butanone, which is mainly produced through the dehydrogenation of butanol in industry. In this research, the effect of the framework Si/Al ratio on 2,3-butanediol dehydration over HZSM-5 zeolites (Si/Al = 38–360) was investigated.…
The analysis of engineered nanomaterials (ENMs), especially engineered nanoparticles (ENPs), is a fast growing analytical research field. New trends in plasma spectrometry such as direct single particle inductively coupled plasma mass spectrometry (spICPMS) or the coupling of asymmetric flow field flow fractionation t…
A new helical aromatic oligoamide foldamer, bearing triethyleneglycol side chains for solubility in a broad range of media, was prepared. The stability of the helical conformation was assessed in various solvents and shown to vary greatly and unexpectedly. Stability was remarkably enhanced in methanol-water mixtures.
Exploration of new catalytic semiconductors with novel structures as counter electrode materials is a promising approach to improve performances of quantum dot sensitized solar cells (QDSSCs). In this work, nearly mono-disperse tetragonal Cu(2)SnS(3) (CTS) and rhombohedral Cu(1.8)S hierarchical microspheres with nanom…
Over the past few years, isoindoles have found wide application in materials science. Isoindole containing BODIPY dyes are highly fluorescent materials and have been extensively used in various fields of science. Phthalocyanines, metal containing cyclic tetramers of isoindole, form coordination complexes with most ele…
Water oxidation is the crucial stage in the chemical and molecular sequence of photosynthesis, designed by Nature to convert solar light into chemical energy. The artificial “off-leaf” transposition is a major goal of energy research, aiming at the continuous production of hydrogen as a solar fuel, through the photo-c…
A simple colorimetric method with high sensitivity and selectivity was developed for sensing of nitrite as low as 4.0 μM by naked eyes, which is based on etching of gold nanorods accompanied by shape changes in aspect ratios (length/width) and a visible color change from bluish green to red and then to colorless with…
We present here for the first time an electrochemical switching for reversible superoleophobic polyaniline (PANI) nanowire film from the pinned to the rolling state underwater. Importantly, based on the unique adhesive switching, a “mechanical hand” for oil droplet transportation without loss was easily achieved by ap…
A method of obtaining a hydrophilic and antifouling poly(vinylidene fluoride) (PVDF) membrane is developed via in situ polymerisation of 2-hydroxyethyl methacrylate (HEMA) in PVDF solution and subsequent micro-phase separation. The immobilization of PHEMA in a PVDF membrane was verified by Fourier Transform Infrared S…
A polymeric fluorescent sensor PNME, consisting of A4 and N-isopropylacrylamide (NIPAM) units, was synthesized. PNME exhibited dual responses to pH and temperature, and could be used as an intracellular pH sensor for lysosomes imaging. Moreover, it also could sense different temperature change in living cells at 25 an…
Hybrid Fe(3)O(4)@SiO(2)@PEG-Maltose MNPs were synthesized by SI-ATRP of branched PEG brushes on the surface and subsequent functionalization with hydrophilic maltose group, and the multifunctional materials were utilized for selective enrichment of N-linked glycopeptides from biological samples with high specifity, hi…
