A novel dual-emitting fluorescence probe is developed for rapid and ultrasensitive detection of Fe(3+). The nanoprobe is prepared by coating CdSe semiconductor quantum dots (SQDs) onto the surface of carbon nanodot (CND) doped TiO2 microspheres. The as-prepared nanoprobe exhibits the corresponding dual emissions at 43…
The growth stimulation of gram plants ( <italic>Cicer arietinum</italic> ) by water dispersible carbon nanostructures is found to be dependent on the latter's morphology.
A tetragonal Cu2Se film containing a well-aligned nanosheet array with scattered 3D flower-like microstructures on top was synthesized for the first time by a rapid one-step low-energy route, which is beneficial for large scale industrial production due to savings in energy, time and expensive instruments. Phase trans…
A novel heterogeneous copper catalyst based on a 3D-network polymer containing pendant amine groups was synthesized <italic>via</italic> post-functionalization of the polymeric backbone followed by incorporation of copper( <sc>i</sc> ) ions.
We report a novel and facile self-limiting synthesis route of silicon nanocrystal (Si NC)-based colloidally stable semiconductor-metal (gold, silver and platinum) hybrid nanoparticles (NPs). For the formation of hybrid NPs, we employ ligand-free colloidal Si NCs with heavily boron (B) and phosphorus (P) doped shells.…
Chiral nematic liquid crystals possess a self-assembled helical structure and exhibit unique selective reflection in visible and infrared light regions. Their optical properties can be electrically tuned. The tuning involves the unwinding and restoring of the helical structure. We carried out an experimental study on…
The shear flow of microfibrillated cellulose dispersions is still not wholly understood as a consequence of their multi-length-scale heterogeneity. We added carboxymethyl cellulose, a charged polymer, that makes cellulose microfibril dispersions more homogeneous at the submicron and macro scales. We then compared the…
Metal-tube contact is known to play an important role in carbon nanotube field-effect transistors (CNT-FETs) which are fabricated on individual CNTs. Less attention has been paid to the contact effect in network type carbon nanotube thin film transistors (CNT-TFTs). In this study, we demonstrate that contact plays an…
We present a comprehensive simulation study of the effect of composition on the structural, elastic and thermal properties of 25 different compounds from the pyrochlore family.
Here, we developed a one-step method for covalent edge functionalization of semiconducting MoS <sub>2</sub> with lipoic acid.

A new noncentrosymmetric borate, Na3Y3(BO3)4, was grown in the Na2O-B2O3-NaF flux system. Its open-framework structure features a large hexagonal tunnel (5.92 Å in diameter), which is extremely rare in borates. First-principles calculations on its kinetic stability and optical properties were performed.
Through the matching of the honeycomb-shaped NiCo <sub>2</sub> O <sub>4</sub> /CC (HSNC) and reduced graphene oxide/carbon cloth (rGO/CC) to obtain the binder-free asymmetric electrochemical capacitor with high energy density good rate capability and excellent cycle life.
Nonepitaxial multilayer silicene with a lonsdaleite structure was synthesized from a 4H-SiC substrate using an implantation-assisted process. An sp(3)-like bonding signal was fitted in a lonsdaleite Si XPS spectrum. The multilayer silicene was directly observed and the derived interplanar distances were found to be ne…
Inexpensive 1,1'-thiocarbonyldiimidazole and di(2-pyridyl) thionocarbonate have been used as respective sulfide precursors to assemble unprecedented high-nuclearity ethynide-stabilized silver(i) sulfido molecular clusters [Ag9S6@Ag36(C[triple bond, length as m-dash]C(t)Bu)32(H2O)2] [Ag(imidazole)(CH3OH)(H2O)](BF4)2·8H…
Nanostructured biomimetic birnessite Ca <sub>x</sub> MnO <sub>y</sub> oxides with an intermediate Mn oxidation state and proper structural distortion show improved catalytic activity for the WOR.
Abstract Catalyst-free thermal polyesterification has recently emerged as a potential strategy for designing biodegradable thermoset polymers, particularly polyol-based polyesters for biomedical applications. These thermoset polyesters are synthesized through polycondensation of polyol and polyacid without the presenc…
The facile, rapid, and complete reductive dissolution of CeO <sub>2</sub> and ceria-based oxides, known to be highly refractive materials towards dissolution, is reported for the first time in very mild conditions.
Nano-precipitates of Sm-doped CeO <sub>2</sub> were uniformly coated onto porous Pt thin films <italic>via</italic> cathodic electrochemical deposition. Deposition of only 5 min created an oxide coating that increased the values of the electrode conductance by more than two orders of magnitude and provided outstanding…
Cubic fluorite-type phases have been reported in the U(IV)O2-Bi2O3 system for the entire compositional range, but an unusual non-linear variation of the lattice parameter with uranium substitution has been observed. In the current extensive investigation of the uranium(iv) oxide-bismuth(iii) oxide system, this behavio…
