We have described the catalytic application of a manganese containing ionic liquid-based ordered mesoporous organosilica in the synthesis of polyhydroquinolines.
In magnetic resonance imaging, contrast agents are molecules that increase the contrast-to-noise ratio of non-invasively acquired images. The information gained from magnetic resonance imaging can be increased using responsive contrast agents that undergo chemical changes, and consequently changes to contrast enhancem…
Investigation of electron beam irradiated EVA/TPU blends leads to significant improvements in performance properties suitable for various technological applications.
Shape memory hydrogels offer the ability to recover their permanent shape from temporarily trapped shapes without application of external forces. Here, we report a novel dual-responsive shape memory hydrogel with characteristic thermoplasticity. The water-insoluble hydrogel is prepared by simple ternary copolymerizati…
Adsorption properties of ethanol on different MgO/SiO <sub>2</sub> surfaces were researched using density functional theory and the result is that ethanol is mainly adsorbed on MgO surface. The role of SiO <sub>2</sub> in increasing the MgO crystal defects in the MgO/SiO <sub>2</sub> has been obtained.
Adhesive biodegradable membranes (patches) for the protection of pruning locations of plants from esca fungi attacks were developed using electrospun soy protein/polyvinyl alcohol and soy protein/polycaprolactone nanofibers. Several different water-soluble adhesives were either added directly to the electrospinning so…
A new and efficient strategy was first employed to fabricate highly elastic nanocomposite hydrogels by surface modification of cellulose nanocrystals.
A cyclic boronate structure was incorporated into Si-rhodamine to design a pH-activatable near-infrared (NIR) probe based on the reversible ring-opening process triggered by H(+). The probe showed general suitability of specific labelling of acidic lysosomes and tracking their pH changes in living cells.
The ferroelectric doped BiFeO <sub>3</sub> thin films exhibit large resistive switching (with ON/OFF ratios ∼10 <sup>4</sup> ) and stably switchable photovoltaic response with good retention properties, providing multiple selections for non-destructive ferroelectric memory diveces.
The chemical binding of amorphous manganese oxide and carbon particles was achieved with the diazonium chemistry. The synthesis was performed in two steps, with a first step consisting in the surface functionnalization of carbon particles with aminophenyl groups and the subsequent attachment of amorphous manganese oxi…
This work concerns a study on the effects of fiber types and content of cellulose nanofiber on mechanical, thermal, and optical properties polyvinyl alcohol (PVA) composites. Two different types of cellulose nanofibers, which are nanofibrillated cellulose (NFC) and bacterial cellulose (BC), were prepared under various…
Introducing ionic interaction into a soft tetraphenylethene-based AIE-molecule furnished the compound with robust mechanochromic effects while exhibiting aggregation-induced emission enhancement properties.
A new chromogenic as well as fluorogenic protocol based on the spirobenzopyran system for the selective detection of nerve agent mimics (diethyl chlorophosphate or DCP vapour) within a few seconds (∼30 s) is designed, synthesized and characterized in this study.
The present study reports the variations in phase content of biphasic mixtures and structural changes induced by different levels of strontium addition in calcium-deficient apatite (Ca/P = 1.60) powders during heat treatment. The synthesis was attempted by an in situ aqueous precipitation technique and X-ray diffracti…
Herein, we suggest a simple chemical precipitation method for the preparation of bare and different levels of Zn doped MnO <sub>2</sub> nanoparticles as electrodes for supercapacitors.
We report non-volatile electric-field control of magnetism modulation in Fe/Pb(Mg1/3Nb2/3)0.7Ti0.3O3 (PMN-PT) heterostructure by fabricating an epitaxial Fe layer on a PMN-PT substrate using a molecular beam epitaxy technique. The remnant magnetization with a different electric field shows a non-symmetric loop-like sh…
Cambered nano-walls of SnO <sub>2</sub> /rGO composites with controllable thickness were synthesized by using a recyclable melamine template.
In this work, we present large scale, ultralight aligned carbon nanotube (CNT) structures which have densities an order of magnitude lower than CNT arrays, have tunable properties and exhibit resiliency after compression. By stacking aligned sheets of carbon nanotubes and then infiltrating with a pyrolytic carbon (PyC…
Homogenously hexagonal prismatic AgBiS2 nanocrystals with sizes of about 7.6 nm have been synthesized by the selective absorption of oleylamine and anisotropic growth in a mixed solvent system. Quantum dot-sensitized solar cells with the as-prepared AgBiS2 nanocrystals as counterelectrode materials showed a conversion…
With intent to fine tune the morphological and photophysical properties, three novel AIE luminogens (BQ1-BQ3) based on quinoline-BODIPY have been synthesized. A judicious choice of substituents (-H, -CH3, -OCH3) in these systems led to nanoballs in BQ1 and BQ2, while in BQ3 it led to reticulated nanofibers with divers…
