In this study, novel graphene oxide (GO)-decorated hybrid fiber sheets composed of poly(lactic-co-glycolic acid, PLGA) and collagen (Col) (GO-PLGA/Col) for application to tissue engineering scaffolds were prepared via dual electrospinning. Physicochemical properties of GO-PLGA/Col fiber sheets were characterized by fi…
A MnFe 2 O 4 –reduced graphene oxide (rGO) nanocomposite was successfully synthesized by a one-pot low-temperature process by coprecipitation of Mn ions produced in the modified Hummer's method and in situ reduction of GO at 90 °C.
Previous experimental results have shown that a system with molten carbonate and solid oxide electrolyte is feasible for Direct Carbon Fuel Cell (DCFC).A study is presented to investigate cell performance with a range of solid carbon (i.e.coals, biochars, graphite) and operation mode in this hybrid electrolyte system.…
Binder-free films of nitrogen-enriched nanocarbons, prepared by the pyrolysis of polyacrylonitrile-block-poly(n-butyl acrylate) copolymer drop-casted on glassy carbon disk electrode, exhibited high electrocatalytic activity for the oxygen reduction reaction (ORR), matching that of Pt-based electrocatalyst. Dependence…
Kinetic and DFT results for the carbonate catalysed Co(H2O)6(2+) + H2O2 Fenton-like reaction suggest a mechanism involving the formation of a cyclic transient, cyclic-(CO4)Co(II)(OOH)(H2O)2(-) that decomposes into Co(II)(H2O)(OOH)(OH)2 + CO3˙(-), i.e. no OH˙ radicals are involved. Plausible biological implications are…
[C n C 1 im]I–EMimDCA double salt ionic liquid mixtures presenting low viscosity and high conductivity were used for the preparation of redox active electrolytes that were successfully incorporated into highly efficient dye-sensitized solar cells.
A facile encapsulation strategy was reported for preparing nanoparticles/metal-organic framework hybrid thin films which exhibit both the active (catalytic, magnetic, and optical) properties derived from the NPs and the size-selectivity originating from the well-defined microporous structure of the MOF thin films.
The xFe2O3/yBiOCl composites (xFe/yBi, x/y = 0/100, 5/100, 10/100, 20/100, 30/100 and 40/100 molar ratios) are prepared for the first time through an in situ hydrolysis method under hydrothermal conditions. The samples are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution tr…
Dissemination of circulating tumor cells (CTCs) in blood and their hetero-adhesion to vascular endothelial bed of distant metastatic secondary organs are the critical steps to initiate cancer metastasis. The rarity of CTCs made their in vivo capture technically challenging. Current techniques by virtue of nanostructur…
Biofunctionalized quantum dots (QDs), especially protein-coated QDs, are known to be useful targeted fluorescent labels for cellular and deep-tissue imaging. These nanoparticles can also serve as efficient energy donors in fluorescence resonance energy transfer (FRET) binding assays for the multiplexed sensing of tumo…
Prussian blue (PB) and its analogues (PBAs) have been intensively studied and are now increasingly attractive for battery applications in particular because of their ability to accommodate a wide variety of ions including polyvalent cations. The redox reactions of PB and PBAs are believed to be very fast and reversibl…
Much enhanced capacity retention abilities, improved high-rate performance and long-term stability have been attained for LiV 3 O 8 nanorods synthesized by a two-step route using VO 2 (B) nanosheets as the precursor.
In this work, a novel graphene–polyaniline nanocomposite thin film was prepared by the electrostatic layer-by-layer assembly of positively charged graphene sheets functionalized by ionic liquid (IL-GR) and negatively charged sulfonated polyaniline (s-PANI). The use of IL not only enhanced the dispersibility of the gra…
Modern medicine faces a growing crisis as demand for organ transplantations continues to far outstrip supply. By stimulating the body's own repair mechanisms, regenerative medicine aims to reduce demand for organs, while the closely related field of tissue engineering promises to deliver "off-the-self" organs grown fr…
Many surgical techniques are available for bridging peripheral nerve defects. Autologous nerve grafts are the current gold standard for most clinical conditions. In selected cases, alternative types of conduits can be used. Although most efforts are today directed towards the development of artificial synthetic nerve…
D–π–Cat fluorescent dyes YM-1 and YM-2 with a diphenylamine moiety as the electron-donating group, a catechol (Cat) unit as the anchoring group and fluorene or carbazole as the π-conjugated system were designed and developed as a photosensitizer for type-II dye-sensitized solar cells (DSSCs), which have a direct elect…
Vertically oriented graphene exhibits meritorious electrocatalytic properties due to exposed graphene edges and other defects, even without any heteroatom functionalization.
An efficient route for the synthesis of all four diastereomers of PMP-protected α-amino-γ-butyrolacton to access γ-hydroxynorvaline was established. The asymmetric key steps comprise an organocatalytic Mannich reaction and an enzymatic ketone reduction. Three reaction steps could be integrated in a one-pot process, us…
A copper( i )/ketoABNO aerobic catalyst system is highly effective for the oxidation of secondary alcohols, including unactivated aliphatic substrates. The effects of pressure and gas composition on catalyst performance are examined. The radical can be employed at low loadings and it is also amenable to immobilisation…
Based on the protective properties of carbon nanoparticles for aptamers against the digestion of nuclease, we have developed a nuclease-assisted target recycling signal amplification method for highly sensitive detection of biomolecules, such as ATP and kanamycin. The high binding specificity between aptamers and targ…
