The influence of defects (such as vacancy and substitution atom) on SERS of graphene has been investigated systematically. It is found that B-substituted graphene has a positive effect on SERS with an enhancement factor of 103 to 104 and a frequency shift of approximately 30 cm−1, resulting from the electronic attract…
Vertically aligned indium doped zinc oxide (IZO) nanorods (NRs) have been grown without any external catalyst on an indium tin oxide (ITO) coated glass substrate by radio frequency magnetron sputtering. Wurtzite IZO NRs distributed homogeneously on the substrate with a preferential orientation along the (002) crystall…
Consecutive synthesis methodologies for the preparation of the gold(I) carboxylates [(Ph(3)P)AuO(2)CCH(2)(OCH(2)CH(2))(n)OCH(3)] (n = 0-6) (6a-g) are reported, whereby selective mono-alkylation of diols HO(CH(2)CH(2)O)(n)H (n = 0-6), Williamson ether synthesis and metal carboxylate (Ag, Au) formation are the key steps…
We report the role of the molecular structure and molecular interactions of linear shaped bi-1,3,4-oxadiazole derivatives (BOXD-n) on their self-assembly behaviors and optical properties. The terminal chains of BOXD-n (n = 1, 4) play an important role in molecular self-assembling and their optical properties. High flu…
A pioneering work for determining the extinction coefficient of colloidal semiconductor nanocrystals (NCs) has been cited over 1500 times (W. Yu, W. Guo, X. G. Peng, Chem. Mater., 2003, 15, 2854-2860), indicating the importance of calculating NC concentration for further research and applications. In this study, the s…
Applications of localized surface plasmon resonance (LSPR) such as surface enhanced Raman scattering (SERS) devices, biosensors, and nano-optics are growing.
A multifunctional nanoparticle based on carboxymethyl cellulose was developed. Folate group was attached to nanoparticle for specific recognition of cancerous cells and 5FU was encapsulated for delivering cytotoxicity. The whole system was able to track by the semiconductor quantum dots that were attached to the nanop…
Nanoscale wear particles would generate from orthopedic implants with nanoscale surface topography because of residual stress. In this study, the effect of TiO 2 nanoparticles on articular cartilage was investigated by intra‐articular injection in rats. Using contrast‐enhanced high‐resolution microcomputed tomography…
Multiwalled carbon nanotubes have been shown to possess unusual fibrogenic activity in vivo and are currently the focus of intense toxicological investigations. This study further determines the fibrogenic potential of well‐dispersed MWCNT in human lung cell culture models and to develop a novel platform for understan…
Two new discotic liquid crystals based on the triazatruxene core, TAT-1 and TAT-2, have been constructed using diamine–diketone condensation as the key expansion step with different solubilizing chains attached at the periphery. The new mesogens possess good thermal stability and show columnar liquid crystalline prope…
A novel strategy is proposed to prepare hexagonal EuF3 nanocrystals by doping lanthanide ions (Ln3+) with large ionic radius (such as La3+, Ce3+, Pr3+, Nd3+ and Sm3+). Complete phase transition from orthorhombic to hexagonal phase can be achieved with the increase of ionic radius or doping concentration of Ln3+ ions.…
Bi2O3-nucleated melilite based glasses and glass-ceramics (GCs) in the system CaO–MgO–Al2O3–SiO2–La2O3 have been appraised for solid electrolyte sealing applications in high-temperature electrochemical devices, such as solid oxide fuel cells and oxygen pumps . The structure of the glasses was assessed by Fourier trans…
We aim to introduce photoactivated optical ion sensors based on a triggered ion exchange process as novel dynamic tools. The quantification of the acidity change upon photoactivation of spiropyran within an organic membrane phase during photoexcitation is described here for the first time, suggesting a large pK(a) cha…
Copper@carbon nanowires (NWs) or nanorods (NRs) with outer diameters between 30 and 90 nm and lengths ranging from 700 nm up to 10 μm have been prepared with high yield via a chemical vapor deposition (CVD) method followed by thermal decomposition of copper(II)-acetylacetonate. The morphology and microstructure of the…
Mesoporous carbon materials with controlled pore and wall structures have promising applications in energy storage. In this work, we prepare a series of ordered mesoporous carbons (OMCs) by adjusting the pyrolysis temperature via a soft templating and catalytic graphitization approach. The structure of graphitic tubul…
Simultaneous removal of low concentration formaldehyde (HCHO) and ozone byproduct was investigated in the gaseous VUV (vacuum ultraviolet) photocatalysis by using noble metal modified TiO 2 films. Noble metal (Pt, Au, or Pd) nanoparticles were deposited on TiO 2 films with ultrafine particle size and uniform distribut…
We investigate the properties of freely suspended nematic nanodroplets of increasing size formed by elongated Gay–Berne mesogens, using extensive molecular dynamics simulations. We find that the nanodroplets have an elongated shape with an aspect ratio changing with size and that in the 50–100 nm size range (N ≈ 50 00…
Graphene oxide‐gold composites were prepared by one‐step reaction in aqueous solution, where the gold nanoparticles were deposited on the graphene oxide during their synthesis process. Transmission electron morphology, X‐ray diffraction, Roman spectra, and UV‐Vis absorption spectra were used to characterize the obtain…
We present here the micropatterns of layer-by-layer (LbL) assembled soft films generated using microfluidic platform that can be exploited for selective cell growth. Using this method, the issue of cell adhesion and spreading on soft LbL-derived films, and simultaneous utilisation of such unmodified soft films to expl…
