By designing a fine-controlled nanocomposite with Au nanoparticles (∼2 nm in size) directly inlaid in TiO2 as working electrode, efficiency (η) of 10.1% for a dye-sensitized solar cell with an open-circuit photovoltage of 863 mV and a short-circuit photocurrent of 15.71 mA cm−2 have been achieved, giving an enhancemen…
One dimensional core/shell nanostructures consisting of two different semiconductors with appropriate band alignment are promising for photocatalytic hydrogen production due to their efficient light harvesting and fast carrier transport. In this work, CdS/ZnO core/shell nanofibers were successfully synthesized by one-…
In this paper, we have demonstrated a facile and environmentally friendly approach to prepare Fe3O4/Ag@nanofibrillated cellulose (NFC) nanocomposites which enables tunability from highly porous, flexible aerogels to solid and stiff films. In the procedure, NFC acts as (i) a biocompatible support for the magnetic silve…
We report a facile soft-chemical approach for the fabrication of Fe3O4 embedded ZnO magnetic semiconductor nanocomposites (Fe3O4–ZnO MSN), and investigate and compare their efficacy for the detoxification of water with respect to their individual counterparts (Fe3O4 and ZnO). The formation of Fe3O4–ZnO MSN was evident…
Graphene, as a rising star in the field of nanomaterials, possesses a unique planar structure and exceptional electronic, mechanical, and optical properties. The material has attracted tremendous interest not only for its intrinsic properties but also promising application opportunities in a wide range of technologies…
A novel photocatalytic nanocomposite, Ag–AgBr/TiO2 supported on reduced graphene oxide (Ag–AgBr/TiO2/RGO), was synthesized via a facile solvothermal–photoreduction method using titanium butoxide, cetyltrimethylammonium bromide (CTAB), AgNO3 and graphene oxide (GO), during which the crystallization of TiO2, Ag nanopart…
For ratiometric "naked eye" detection of CN(-), an ESIPT exhibiting benzothiazole receptor (BHI) is designed having one aldehyde group ortho and the other aldehyde para to the OH group respectively. Due to RAHBs, the ortho aldehyde group is highly reactive undergoing nucleophilic cyanide addition selectively, which ha…
Here we report a green and facile strategy for the direct nucleation and growth of ultrafine (1.8 nm) and well dispersed Au@Pd core–shell nanoclusters on nitrogen-doped mildly reduced graphene oxide (Au@Pd/N–mrGO) without any surfactant and additional reducing agent. During the synthesis, N–mrGO acts as both the reduc…
A sandwich-like N-doped graphene/Co3O4 hybrid was prepared via a simple one-pot hydrothermal reaction in a solution of NH3. Characterizations disclosed that highly dispersed Co3O4 nanoparticles with dominant exposed {112} and {110} planes were fabricated on both sides of well-exfoliated N-doped graphene; N-dopants in…
With the development of cancer immunotherapy, cancer vaccine has become a novel modality for cancer treatment, and the important role of adjuvant has been realized recently. Chitin, chitosan, and their derivatives have shown their advantages as adjuvants for cancer vaccine. In this paper, the adjuvant properties of ch…
Polymer-based materials with a high dielectric constant show great potential for energy storage applications. Since the intrinsic dielectric constant of most polymers is very low, the integration of carbon nanotubes (CNTs) into the polymers provides an attractive and promising way to reach a high dielectric constant o…
In this study, a magnetically-recoverable catalyst (Fe3O4@SiO2-HPW) was prepared by the application of phosphotungstic acid (HPW) supported on silica-coated Fe3O4 nanoparticles. The prepared samples were characterized by XRD, TEM, FT-IR, and N2-adsorption–desorption isotherms. The content of W in Fe3O4@SiO2-HPW was me…
Cerium dioxide/graphitic carbon nitride (CeO2/g-C3N4) visible-light-induced photocatalysts were successfully prepared by a simple mixing-calcination technique. The CeO2/g-C3N4 nanocomposites were characterized by thermogravimetric analysis (TG), powder X-ray diffraction (XRD), transmission electron microscopy (TEM), U…
A graphene based composite with copper nanoparticles (Cu–G) has been synthesized and used as catalyst for N-arylation and O-arylation. The structure and composition of the nanocomposite have been characterized by TEM, AFM, Raman and XPS. The catalytic activity of the Cu–G has been tested for the N-arylation of N–H het…
A simple and generalized approach to build electrochemical sensors for wearable devices is presented. Commercial cotton yarns are first turned into electrical conductors through a simple dyeing process using a carbon nanotube ink. These conductive yarns are then partially coated with a suitable polymeric membrane to b…
Developments in the field of fluorescent chemosensors for trace level determination of Al3+ have been described. Design, synthesis and applications of Al3+ selective fluorescent sensors have attracted a great deal of attention due to their versatile and emerging biological implications. A systematic description of dif…
BiVO4 and many other semiconductor materials are ideal visible light responsive semiconductors, but are insufficient for overall water splitting. Upon loading water oxidation cocatalyst, for example Co-borate (denoted as CoBi) used here, onto BiVO4 photoanode, it is found that not only the onset potential is negativel…
The trifluoroacetyl acetonate naphthalimide derivative 1 has been synthesized in good yield. In acetonitrile solution, compound 1 reacts selectively with hydrazine (NH2NH2) to give a five-membered ring. This leads to OFF–ON fluorescence with a maximum intensity at 501 nm as well as easily discernible color changes. Ba…
Colloidal crystals (CCs) are ordered arrays of monodisperse colloidal particles. Because of the presence of a periodic superlattice of colloids and voids, CCs bear many unique structures and fascinating properties which are distinctly different from those of standard crystals with atoms, ions or molecules as repeating…
In this article, we demonstrate the application of digital image correlation (DIC) in evaluating the strains and Poisson ratio of a range of soft materials in terms of their spatial and temporal resolutions. Homogeneous samples of polydimethylsiloxane (PDMS) elastomer were used as control substance and were measured t…
