Three-dimensional matrices with controllable and sustainable delivery capacity of neurotrophic factors are promising platforms for neural tissue engineering. Here we developed a nerve growth factor (NGF) delivering cell culture system involving mesoporous silica nanoparticles (MSNs) combined with collagen hydrogel. Pa…
An interparticle binding agent, or nanoglue, was synthesized by a sol-gel process, which facilitated the preparation of well-interconnected TiO2 electrodes at low-temperatures for plastic dye-sensitized solar cells. The viscosity of the nanoglue-based pastes was seven times higher than that obtained in pastes without…
Mesoporous silica-coated silver nanoparticles (Ag@MSN) were prepared by a two step synthesis in an environment friendly way. Arginine and glucose were used as a catalyst for the formation of silica and as a reducing agent for silver ions, respectively, in the presence of a cationic surfactant. Ag@MSNs having single Ag…
We have grown γ-phase layered In2Se3 crystals with various thicknesses from hundreds of nm to hundreds of μm. The as-grown layers showed different crystal colors from light yellow to dark red owing to their different thicknesses. The direct band edge of γ-In2Se3 has been probed by transmittance and thermoreflectance m…
A self-templating method to fabricate a super-hydrophobic yolk-shell nano-reactor was reported. Metal nanoparticles were encapsulated in the porous super-hydrophobic shell. This super-hydrophobic catalyst showed excellent performance in the reduction of nitroaromatic compounds in aqueous phase and a positive correlati…
The aim of this study was to investigate the combined influence of 3 independent variables in the preparation of paclitaxel containing pH-sensitive liposomes. A 3 factor, 3 levels Box-Behnken design was used to derive a second order polynomial equation and construct contour plots to predict responses. The independent…
In the present work we report the synthesis and the electrochemical, photoluminescent and electroluminescent properties of two new Ru(II) complexes described by the general formula [Ru(phen)2X](2+), where phen is 1,10-phenanthroline. The X ligand consists of a 2,2'-bipyridine (bpy) unit substituted with two phenyl rin…
A novel single-layer reflectarray element with an I-shaped dipole encompassed by a circular ring, showing smooth phase-frequency response, is proposed in this letter. Based on this element, an optimization method is adopted to match the desired phase delays at two edge frequencies so as to get fixed phase difference b…
Photoexcitation of a Zn(II)-trimesic acid based metal organic framework containing co-encapsulated Ru(II)tris(2,2′-bipyridine) (RuBpy) and Co(II)tris(2,2′-bipyridine) (CoBpy) results in inter-molecular electron transfer (ET) between the excited state of RuBpy (3MLCT) and the ground state CoBpy The rate of inter-cavity…
Using Molecular Dynamics simulations of a polymer liquid flowing past flat and patterned surfaces, we investigate the influence of corrugation, wettability and pressure on slippage and friction at the solid–liquid interface. For one-dimensional, shallow, rectangular grooves, we observe a gradual crossover between the…
The understanding of both cell-extracellular matrix (ECM) and cell-material interactions is crucial for the success of implantable biomaterials including tissue engineering devices. ECM is rich in sulfated and aminated glycosaminoglycans and proteoglycans. The development of synthetic models containing those chemical…
BACKGROUND AND AIMS: Raman spectroscopy is a vibrational technique which provides information about the chemical structure. Nevertheless, since many chemicals are present in a cell at very low concentration, the Raman signal observed from a single cell is extremely weak. In surface enhanced Raman scattering (SERS), Ra…
Through a stepwise fragment coupling approach, a family of novel platinum-acetylide metallocycles with well-defined shape and size were successfully constructed. Their aggregation behavior was investigated.
A metal-organic framework, [{Fe(NCS)2}3(TPB)4]·x(guest) [·x(guest), TPB = 1,3,5-tris(4-pyridyl)benzene], shows selective gas adsorption and guest-dependent spin-crossover behaviour.
Since the C60 and graphene were discovered, carbon allotropes have attracted an increasing attention. Here we designed a porous diamond-like carbon framework (named as D-carbon) by inserting –CC– linkers into all the C–C bonds in a diamond, which is a new carbon allotrope formed by sp3–sp hybridized carbon atoms. Inte…
We have demonstrated an efficient phosphorescence energy transfer (PET) system for ultrasensitive detection of DNA.
A facile method was developed for large-scale preparation of porous worm-like Pd nanotubes based on the reduction of PdO nanotubes, which were obtained by calcining the complex precipitate of [Pd(dimethylglyoxime)2]n. The Pd catalyst showed excellent electrocatalytic activity and stability towards ethylene glycol oxid…
2-D layer type porous coordination polymers containing redox active Fe2+ centers were synthesized. One of the compounds [Fe(isophthalate)(4,4′-bipyridyl)] showed structural flexibility via guest adsorption, and we observed reversible Fe2+ and Fe3+ switching by iodine insertion. The composite showed electric conductivi…
The colloidal properties of casein micelles in heated milk as a function of volume fraction are largely unknown. Heat-treatment of milk causes denaturation and unfolding of whey proteins, which then react with caseins to form a complex mixture of soluble whey protein aggregates and whey protein coated casein micelles.…
An integrated self-powered fluorescence switch system based on biofuel cells (BFCs) is initially presented in this paper. With the aid of the electroactive material Prussian blue (PB) as the controller of fluorescence change and the biocatalysis, the fluorescence switch and electricity generation could be achieved in…
