A new proton conductor based on niobium phosphates was synthesized using niobium pentoxide and phosphoric acid as precursors. The existence of hydroxyl groups in the phosphates was confirmed and found to be preserved aft...
Three-dimensional (3D) structures of graphene have attracted extensive interest for their practical applications, such as supercapacitors and catalyst supports. Self-assembly is a typical technique to fabricate macroscop...
A novel series of nanocomposite hydrogels based on cellulose nanocrystals (CNCs) and poly(acrylic acid) (PAA) have been synthesized by in situ free radical polymerization within an aqueous medium. Rheological measurement...
Facile synthesis of a chlorophenyl decorated graphene (CBG) sheet synthesized by a solvent free green diazotization technique is reported here. The functionalization of the material was supported by various characterizat...
Here we present a useful ammonia (NH3) gas sensor based on reduced graphene oxide (RGO)-polyaniline (PANT) hybrids. PANI nanoparticles were successfully anchored on the surface of RGO sheets by using RGO-MnO2 hybrids as ...
A novel butterfly-like Ir(III) complex is designed, synthesized, and characterized for highly efficient yellow phosphorescent polymer-based light-emitting diodes (PLEDs). The device shows a maximum external quantum effic...
Synchrotron-based X-rays were used to probe active materials for polymer solar cells on flexible polyester foil. The active material was coated onto a flexible 130 micron thick polyester foil using roll-to-roll different...
A facile solvothermal approach was used to synthesize monodispersed ultrathin GdF3 nanowires via an oriented attachment mechanism. Gadolinium nitrate acted as the Gd source, n-octylamine and oleic acid as capping ligands...
A recently synthesized conducting polymer poly(TBT6-NH2); poly(6-(4,7-di(thiophen-2-yl)-2H-benzo [d][1,2,3]triazol-2-yl)hexan-1-amine) was utilized as a matrix for biomolecule immobilization. After successful electrochem...
We investigate the possibility of tuning the selectivity and sensitivity of SiO2/TiO2 mesoporous dielectric multilayers for the adsorption of analytes with different chemical polarities. The hydrophilic-hydrophobic balan...
Well-dispersed Pd nanoparticles supported on low-defect graphene (LDG) sheets are successfully prepared by a soft chemical method. Our approach can efficiently avoid damaging the graphene framework in the composite becau...
A porous Ni@rGO nanocomposite was successfully prepared by the ethylene glycol method followed by an annealing process. It was shown that fcc Ni nanoparticles anchored on reduced graphene oxide sheets producing a porous ...
Four new donor-pi-acceptor organic dyes (YF01-04), containing naphthalene-substituted amines as an electron donor and cyanoacrylic acid as an electron acceptor, were designed and synthesized, and their photophysical prop...
As part of our efforts to access the biaxial nematic phase at low temperatures, we prepared a series of 1,3,4-oxadiazole-based bent-core mesogens that possess either one or three lateral methyl groups. The phase behavior...
Biomedical scaffolds need to be designed to support high seeding efficiency and facilitate high cellular activities (proliferation and differentiation) of injected cells with appropriate mechanical properties. In this st...
A dextran based pH-sensitive near-infrared nanoprobe was prepared and applied as a contrast agent for photoacoustic imaging to identify a tumor in vivo. The nanoprobe has two resonance absorption peaks in the near-infrar...
