Multi-shape-memory effects in a wavelength-selective multicomposite
Tuneable shape-memory effects can be achieved in a wavelength-selective multicomposite.
Fluorinated graphene dielectric films obtained from functionalized graphene suspension: preparation and properties
In the present study, we have examined the interaction between a suspension of graphene in dimethylformamide and an aqueous solution of hydrofluoric acid, which was found to result in partial fluorination of suspension flakes. A considerable decrease in the thickness and lateral size of the graphene flakes (up to 1-5…
In situ fabrication of graphene decorated microstructured globe artichokes of partial molar nickel cobaltite anchored on a Ni foam as a high-performance supercapacitor electrode
3D microstructured globe artichokes of a rGO/Ni 0.3 Co 2.7 O 4 composite were synthesized through a hydrothermal method to contribute an efficient work nature as supercapacitor electrodes.
Atmospheric pitting corrosion of 304L stainless steel: the role of highly concentrated chloride solutions
The morphology of atmospheric pitting corrosion in 304L stainless steel plate was analysed using MgCl(2) droplets in relation to changes in relative humidity (RH) and chloride deposition density (CDD). It was found that highly reproducible morphologies occur that are distinct at different RH. Pitting at higher concent…
Biosynthesis of Silver Nanoparticles by Aspergillus oryzae (MTCC No. 1846) and Its Characterizations
Biosynthesis of silver nanopartcles by Aspergillus oryzae (MTCC No. 1846) was demonstrated using both the fungal cell filtrate and the fungal biomass. In the present study, the fungal cell filtrate was used for extracellular biosynthesis of silver nanoparticles (AgNPs) from silver nitrate (AgNO3) solution. When the aq…
Use of Cellulose and Oxidized Cellulose Nanocrystals from Olive Stones in Chitosan Bionanocomposites
Cellulose nanocrystals (CNC) and 2,2,6,6‐tetramethyl‐1‐piperidinyloxyl‐ (TEMPO‐) oxidized cellulose nanocrystals (CNC‐TEMPO) were prepared from olive stones. The prepared nanocrystals were characterized using transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and carboxylic groups…
Correlated DFT and electrochemical study on inhibition behavior of ethyl 6-amino-5-cyano-2-methyl-4-(p-tolyl)-4H-pyran-3-carboxylate for the corrosion of mild steel in HCl
The inhibition effect of ethyl 6-amino-5-cyano-2-me thyl-4-(p-tolyl)-4H-pyran-3-carboxylate (Pyr2) on t he corrosion of mild steel in 1.0 M HCl was investigated by ele ctrochemical (potentiodynamic polarization and elec trochemical impedance spectroscopic studies) and theoretical me thods. The potentiodynamic polariza…
Enhancement of the catalytic activity of ordered mesoporous TiO 2 by using carbon fiber support and appropriate evaluation of synergy between surface adsorption and photocatalysis by Langmuir–Hinshelwood (L–H) integration equation
OMT/CFs show high photoactivity due to some superiorities, and a L–H integration equation is proposed to well evaluate synergy.
Composite silica nanoparticle/polyelectrolyte microcapsules with reduced permeability and enhanced ultrasound sensitivity
nanoparticles were shown to be distributed on the surface or inside the polyelectrolyte shell, acting as supports for free-standing capsules in both liquid and dry environments. Rapid Rh-B molecule release and the fragmentation of the capsule shells were observed under 50 W ultrasound irradiation for a few seconds. Su…
Increasing the effective energy barrier promoted by the change of a counteranion in a Zn–Dy–Zn SMM: slow relaxation via the second excited state
The trinuclear complex [ZnCl(μ-L)Dy(μ-L)ClZn]PF6 exhibits a single-molecule magnetic behaviour under zero field with a relatively large effective energy barrier of 186 cm(-1). Ab initio calculations reveal that the relaxation of the magnetization is symmetry-driven (the Dy(III) ion possesses a C2 symmetry) and occurs…
Catalytic activity of bimetallic catalysts highly sensitive to the atomic composition and phase structure at the nanoscale
The ability to determine the atomic arrangement in nanoalloy catalysts and reveal the detailed structural features responsible for the catalytically active sites is essential for understanding the correlation between the atomic structure and catalytic properties, enabling the preparation of efficient nanoalloy catalys…
