Density functional theory calculations on the CO catalytic oxidation on Al-embedded graphene
The energy barrier of the CO oxidation for the rate limiting step on Al-embedded graphene is only 0.32 eV.
A fluorescent light-up probe with “AIE + ESIPT” characteristics for specific detection of lysosomal esterase
We report a fluorescent light-up probe AIE-Lyso-1 for in situ visualization of lysosomal esterase activity. The probe is based on a salicyladazine fluorogen, which is conjugated with esterase reactive acetoxyl groups and lysosome-targeting morpholine moieties. The probe has characteristics of both aggregation-induced…
Electrochemical synthesis of photoluminescent carbon nanodots from glycine for highly sensitive detection of hemoglobin
An electrochemical approach has been employed for the preparation of photoluminescent carbon nanodots (C-dots) from glycine under alkaline conditions. The formation of C-dots is through electro-oxidation, electro-polymerization, carbonization, and passivation. The as-prepared C-dots possess excitation-wavelength-depen…
Preparation of graphene oxide/epoxy nanocomposites with significantly improved mechanical properties
The effect of graphene oxide (GO) on the mechanical properties and the curing reaction of Diglycidyl Ether of Bisphenol A/F and Triethylenetetramine epoxy system was investigated. GO was prepared by oxidation of graphite flakes and characterized by spectroscopic and microscopic techniques. Epoxy nanocomposites were fa…
Polypyrrole derivatives for electrochromic applications
This review provides a comprehensive assessment of recent progress in polypyrrole derivatives which are specially designed for electrochromic applications.
Highly selective and efficient heavy metal capture with polysulfide intercalated layered double hydroxides
Intercalation of polysulfides into LDHs forms layered composites that can separate Hg 2+ , Ag + and Cu 2+ from mixed ions with high selectivity and capacity.
High throughput electron transfer from carbon dots to chloroplast: a rationale of enhanced photosynthesis
A biocompatible amine functionalized fluorescent carbon dots were developed and isolated for gram scale applications. Such carbogenic quantum dots can strongly conjugate over the surface of the chloroplast and due to that strong interaction the former can easily transfer electrons towards the latter by assistance of a…
Aggregation induced blue-shifted emission – the molecular picture from a QM/MM study
In general, optical emission in the solid-state is red-shifted with respect to the solution phase. A series of recently synthesized compounds exhibits aggregation induced blue-shifted emission (AIBSE) phenomena. By employing a polarizable continuum model (PCM) and a hybrid quantum mechanics/molecular mechanics (QM/MM)…
Sound and Vibration Damping Properties of Flax Fiber Reinforced Composites
In recent days, automobile and construction industries are focus on the light weight, environmental friendly materials with good mechanical properties. Glass fiber reinforced composites have excellent specific properties and are widely used because of reduced mass. However the manufacturing of glass fibers and end of…
Ligands effects on the magnetic anisotropy of tetrahedral cobalt complexes
The effect of ligands with heavy donor atoms on the magnetic anisotropy of the pseudo-tetrahedral cobalt complexes, Co(quinoline)2I2 (1) and Co(EPh3)2I2 (2-3) (E = P, As) has been investigated. The axial zero-field splitting parameter D was found to vary from +9.2 cm(-1) in 1 to -36.9 cm(-1) in 2 and -74.7 cm(-1) in 3…
Photolithographic fabrication of high-performance all-solid-state graphene-based planar micro-supercapacitors with different interdigital fingers
Here we demonstrated the fabrication of ultrahigh rate, all-solid-state, planar interdigital graphene-based micro-supercapacitors (MSCs) manufactured by methane plasma-assisted reduction and photolithographic micro-fabrication of graphene oxide films on silicon wafers. Notably, the electrochemical performance of MSCs…
Self-assembly of colloidal one-dimensional nanocrystals
The ability of nanoscopic materials to self-organize into large-scale assembly structures that exhibit unique collective properties has opened up new and exciting opportunities in the field of nanotechnology. Although earlier work on nanoscale self-assembly has focused on colloidal spherical nanocrystals as building b…

A type-II semiconductor (ZnO/CuS heterostructure) for visible light photocatalysis
Formation of ZnO/CuS heterostructure through a simple wet-chemical method leads to a type-II semiconductor. The heterojunction between these two moieties leads to the separation of electron–hole pairs, which further enhances the photocatalytic efficiency of ZnO.
A triphenylamine-based benzoxazole derivative as a high-contrast piezofluorochromic material induced by protonation
A triphenylamine-based benzoxazole derivative ( BVDP ) as a typical D–π–A molecule could be used as a low contrast piezofluorochromic material with a spectral red-shift of 29 nm. However, when BVDP bound a proton to form BVDP+H , a high contrast piezofluorochromism (Δ λ = 75 nm) could be observed.
