We predict a highly stable and robust atomically thin gold monolayer with a hexagonal close packed lattice stabilized by metallic bonding with contributions from strong relativistic effects and aurophilic interactions. We have shown that the framework of the Au monolayer can survive 10 ps MD annealing simulations up t…
The prepared rGO/Co//AC asymmetric supercapacitor displayed good electrochemical performance, and it achieved a maximum energy density of 40.7 W h kg <sup>−1</sup> at a power density of 1585.0 W kg <sup>−1</sup> .
A ratiometric fluorescent system for CaE detection with AIE dots as the FRET donors was designed. Upon enzymatic reaction, electrostatic interaction between the cationic TPE-N(+) dots and the enzymatic reaction product - the negatively charged fluorescein molecules - allows the FRET process to proceed, thus affording…
values for Au(I) and Au(III) in different buffers are HEPES (0.48 and 1.55 µM) > Trizma (0.41 and 0.57 µM) > PBS (0.14 and 0.06 µM). Bacterial growth inhibition by AuNPs is gradually reduced by centrifugation-resuspension to remove residual Au(III) ion present in the crude synthetic AuNPs. After 4 centrifugations-resu…
Application of surfactants in preparing nano cobalt oxide was effective in achieving a higher specific capacitance.
Coaxial electrospinning was used to fabricate two types of core-shell fibers: the first type with liquid resin monomer in the core and polyacrylonitrile in the shell, and the second type with liquid curing agent in the core and polyacrylonitrile in the shell. These two types of core-shell fibers were mutually entangle…
This work presents a new class of porous graphene particles with a three-dimensional microscale network and an ultrahigh specific surface area (2590 m(2) g(-1)), which is obtained by the KOH activation of a compact graphene hydrogel. As supercapacitor electrodes, such porous graphene particles show high compressibilit…
Variation of specific capacitance of undoped and Mn doped CuO/Cu(OH) <sub>2</sub> hybrid electrodes with corresponding SEM.
NiS2 hollow spheres are successfully prepared by a one-step template free method. Meanwhile, α-NiS hollow spheres can also be synthesized via the calcination of the pre-obtained NiS2 hollow spheres at 400 °C for 1 h in air. The electrochemical performances of the as-prepared NiS2 and α-NiS hollow sphere products are e…
Structural defects can critically influence the electrical and optical properties of monolayered molybdenum disulfide (MoS2) grown by chemical vapor deposition (CVD); thus, convenient optical methods that can visualize grain boundaries (GBs) and other structural defects are in great demand. Although photoluminescence…
Corrosion inhibition studies of mild steel in aqueous HCl by some sulphonamides have been investigated using weight loss, potentiodynamic polarization (PDP), Electrochemical Impedance Spectroscopy (EIS) and Density Functional Theory (DFT).
For manufacturing “bioplastics” such as poly(hydroxyalkanoates) (PHA), the combination of utilization of inexpensive carbon sources with the application of robust microbial production strains is considered a decisive step to make this process more cost-efficient and sustainable. PHA production based on surplus whey fr…
A two-dimensional layered Ti3C2/carbon nanotubes (CNTs) hybrid thin film was prepared. Owing to the excellent conductivity of the CNTs, this unique layered structure provides a rapid charge transfer path during the electrochemical reaction, as a lithium ion battery anode, which exhibits higher capacitance and better c…
A versatile strategy is developed to prepare 2D/3D superhydrophobic porous materials by simply coating substrates with dispersion of PTFPMS aggregations.
A novel hybrid supercapacitor is successfully constructed based on the 3D ordered porous TiNb <sub>2</sub> O <sub>7</sub> electrode (anode) and graphene grass electrode (cathode). In combination with the advantages from the lithium ion batteries and supercapacitors, this device shows superior energy density and power…
PBAT/CS-NF bionanocomposites show an optimal combination of flexibility, strength, barrier, migration, and antibacterial properties, therefore are suitable for food packaging applications.
We propose a novel strategy to fabricate Mo <sub>2</sub> C/GR hybrids through a simple and environmentally friendly carburization process. The as-prepared Mo <sub>2</sub> C/GR hybrids display significantly improved electrochemical performance compared to bulk Mo <sub>2</sub> C and pure GR.
It is of great scientific and practical significance to explore inorganic mimetic enzymes to replace natural enzymes due to their instability and high cost. Herein we present an interesting discovery that a V2O3-ordered mesoporous carbon composite (V2O3-OMC) has a novel peroxidase-like activity towards fast redox reac…

combination of Replica Exchange with Solute Tempering with Metadynamics simulations to predict the adsorption free energy of a gold-binding peptide sequence, AuBP1, at the aqueous Au(111), Au(100)(1 × 1) and Au(100)(5 × 1) interfaces. We find adsorption to the Au(111) surface is stronger than to Au(100), irrespective…
