Methods for the catalytic activation of metallic structured substrates
The review addresses the methods for depositing catalytic layers onto metallic structured substrates, specifically focusing on honeycomb monoliths and open-cell foams.
A donor–acceptor cruciform π-system: high contrast mechanochromic properties and multicolour electrochromic behavior
A donor–acceptor (D–A) cruciform conjugated luminophore DMCS-TPA was designed and synthesized. The DMCS-TPA solid shows both aggregation induced emission (AIE) effect and high contrast mechanochromic (MC) behavior with a remarkable spectral shift of 87 nm. The obvious fluorescence switching from yellowish green to ora…
Elasticity, viscosity, and orientational fluctuations of a lyotropic chromonic nematic liquid crystal disodium cromoglycate
Using dynamic light scattering, we study orientational fluctuation modes in the nematic phase of a self-assembled lyotropic chromonic liquid crystal (LCLC) disodium cromoglycate and measure the Frank elastic moduli and viscosity coefficients. The elastic moduli of splay (K1) and bend (K3) are in the order of 10 pN whi…
Advances in gold nanoparticle–liquid crystal composites
We present the advancement in the research of the dispersion of gold nanoparticles (GNPs) in thermotropic calamitic liquid crystals. The formation/behavior of surface plasmon resonance (SPR) in GNPs is briefly described. The uniform dispersion of GNPs into liquid crystals along with two important aspects, i.e. tuning…
Creation of nanopores on graphene planes with MgO template for preparing high-performance supercapacitor electrodes
Creation of nanopores on graphene planar sheets is of great significance in promoting the kinetic diffusion of electrolyte and enhancing the utilization efficiency of graphene planar sheets. Herein, we developed a facile chemical vapor deposition strategy to prepare highly porous graphene with flake-like MgO as templa…
Assessment of Size-Dependent Antimicrobial and Cytotoxic Properties of Silver Nanoparticles
Nanoscale silver has been increasingly applied to commercial products for their antimicrobial function as antibiotics and disinfectants. In this work, the different sizes of silver nanoparticles (AgNPs) were studied not only in Methylobacterium spp . for their antimicrobial potential but also in human peripheral blood…
Highly hydrogen permselective ZIF-8 membranes supported on polydopamine functionalized macroporous stainless-steel-nets
Inspired by the bio-adhesive ability of the marine mussel, highly hydrogen permselective ZIF-8 membranes with a “reinforced concrete” structure were prepared on polydopamine functionalized inexpensive macroporous stainless-steel-nets.
Giant magnetodielectric and enhanced multiferroic properties of Sm doped bismuth ferrite nanoparticles
Improvements in magnetodielectric and multiferroic properties are essential for visualizing the real application of multiferroics, precisely, BiFeO3 (BFO). An enhancement of multiferroic and magnetodielectric properties has been achieved for chemically prepared nanocrystalline BFO by virtue of Sm doping. The X-ray dif…

The preparation of MnFe2O4 decorated flexible graphene wrapped with PANI and its electrochemical performances for hybrid supercapacitors
A modest, cost effective and eco-friendly method is employed for the preparation of MnFe2O4 nanocube decorated, flexible graphene sheets, followed by polyaniline (PANI) which is wrapped by an in situ chemical oxidative polymerization method. The formation of the hybrid composites and their individual constituents are…
