A stable and effective redox-mediator gel electrolyte has been prepared by doping indigo carmine (IC) into a polyvinyl alcohol sulfuric acid polymer system (PVA–H 2 SO 4 ), and a high performance solid state supercapacitor is fabricated by utilizing activated carbon as electrodes and the prepared gel polymer (PVA–H 2…
Two nanostructured proton-containing δ-MnO 2 (H-δ-MnO 2 ) materials were synthesized through proton exchange for K-containing δ-MnO 2 (K-δ-MnO 2 ) nanosheets and nanoparticles prepared by the hydrothermal homogeneous precipitation method and solid-state reaction.
Chlorosulfonic acid assisted the exfoliation of MoS2 and WS2 resulting in retaining their semiconducting 2H-phase, sharply contrasting the semiconducting-to-metallic phase-transition observed with the currently available exfoliation techniques.
Carbon dot modified mesoporous silica is applied to the efficient removal of both organic and inorganic contaminants.
A wearable wristband from knittable two-ply yarn supercapacitors with high specific length capacitance.
The objective of this work is to prepare and evaluate Poly (D, L-Lactide-co-glycolide) (PLGA) Nanoparticles (NPs) of Capecitabine, an anticancer agent loaded by solvent displacement method using stabilizer (poly vinyl alcohol). The prepared NPs were characterized by FT-IR, DSC, drug loading, entrapment efficiency, par…
Amorphous CeO x -doped Rh-Ni NPs grown on reduced graphene oxide nanosheets have been used as highly efficient and recyclable catalysts for complete hydrogen generation from aqueous solution of N 2 H 4 BH 3 or N 2 H 4 .
Shape memory alloys are used in a variety of fields, such as medical or aeronautical. Other fields of knowledge have been researching these materials, attracted by their capacity to dissipate energy through high-strain hysteretic cycles without significant residual strains. Because of these interesting properties for…
First use of a surfactant-free SnS nanorods synthesized by a solvothermal method in supercapacitor applications having high specific capacitance.
Using a powerful combination of experiments and simulations we demonstrate how the microstructure and its time evolution are linked with mechanical properties in a frustrated, out-of-equilibrium, particle gel under shear. An intermediate volume fraction colloid-polymer gel is used as a model system, allowing quantific…
The basicity of the graphitic, pyridine, and pyrrole nitrogen groups on the graphene and single-walled carbon nanotubes is evaluated and compared in terms of both Brønsted base and Lewis base. It turns out that the pyridine group is the most strong basic site, while the graphitic nitrogen does not bring any improvemen…
AA/BB-type and A2/B3-type FRET-capable supramolecular polymers based on a BODIPY-bridged pillar[5]arene dimer and two BODIPY derivative guests have been successfully constructed and their application in mimicking the light-harvesting system of natural photosynthesis was studied.
This review presents the current progress of 3D structured electrodes, mainly focusing on their design, assembly and applications in supercapacitors. The main challenges and new trends in 3D electrode development have also been proposed.
Layered CuCo 2 O 4 nanosheets@MnO 2 nanoflakes core–shell arrays (CuCo 2 O 4 @MnO 2 CAs) on Ni foam have been uniformly synthesized by fine tuning the operation temperature, exhibiting superior capacitance and excellent electrochemical performance stability.
Ultrathin nanosheet-assembled cobalt molybdate (CoMoO4) with a mesoporous morphology was synthesized by a urea-assisted solution combustion route at a temperature of 400 °C. The as-prepared CoMoO4 was modified using chitosan cross-linked with glutaraldehyde (glu) and employed as a cathode material in an aqueous hybrid…
Covalent organic frameworks with high porosity and crystallinity have been synthesized, through macrocycle-to-framework strategy, using shape-persistent arylene-ethynylene macrocycles as the key components to control the topology and modulate the porosity.
Layered chalcogenide materials (LCMs) are emerging materials in recent years for their great potential in applications of electronics and optoelectronics. As a member of LCMs, SnSe2, an n-type semiconductor with a band gap of ∼1.0 eV, is of great value to explore. In this paper, we develop a facile CVD method, for the…
The corrosion-promotion activity of graphene is inhibited when graphene is encapsulated in insulating SiO 2 because SiO 2 can act as a spacer isolating graphene from the metal substrate so as to prevent graphene–metal micro-galvanic corrosion. Incorporating rGO@SiO 2 nanosheets into a polymer coating also greatly enha…
A combinatorial study on semiconducting ZnSnN 2 , in which the lowest carrier density yet reported for as-deposited films is achieved, wurtzite crystal structure is confirmed, and optical bandgap is established at 1.0 eV.
The first single-ion magnet (SIM) [Co(IMes) 2 ][BPh 4 ] (IMes: 1,3-dimesitylimidazol-2-ylidene) with d 8 electronic configuration has been found in two-coordinate Co( i )–NHC complexes.
