It is of great interest to monitor implants in real-time using non-invasive detecting techniques in interventional therapies or tissue regeneration. In this study, MRI-visible hydrogels that are pH sensitive, injectable and self-healing were prepared based on chitosan and PEG. The macromolecular chelator of Gd(iii), C…
We present a detailed investigation of the effects of synthesis conditions on glasses <italic>x</italic> AgI–(1 − <italic>x</italic> )AgPO <sub>3</sub> with 0 ≤ <italic>x</italic> ≤ 0.4.
The use of high temperature hydrothermal reactions to prepare crystals having mineralogically-related structures is described. Complex naturally occurring minerals can have fascinating structures and exhibit important features like low dimensionality, noncentrosymmetry, or ion channels that can provide excellent guide…
We investigate the polymer packing around nanoparticles and polymer/nanoparticle topological constraints (entanglements) in nanocomposites containing spherical nanoparticles in comparison to pure polymer melts using molecular dynamics (MD) simulations. The polymer-nanoparticle attraction leads to good dispersion of na…
Shown on left is SEM image of MG–AC. Shown on right are C1s XPS spectra of DF–AC. C1s spectra of DF–AC could be deconvoluted into five individual component peaks, indicating the existence of oxygen-containing groups in as-prepared activated carbon.
Montmorillonite nanolayers were treated with chitosan sulfate, as a functional biocompatibilizer, and then exfoliated in chitosan matrix to design nanohybrid membranes for potential wound dressing applications with enhanced physical, mechanical and antibacterial properties.
Fluorine free superhydrophobic coating on cotton fabric by inexpensive dip coating method. The coated fabric exhibited high oil–water separation efficiency.
meso-Substituted boron-dipyrromethene (BODIPY) dyes are a puzzling class of molecules, which feature contrasting emissive behaviors. The full mechanistic picture for these distinctive properties is still missing. Using static and dynamic excited state computations we unravel the key reasons behind these divergences.
A flexible and highly fluorescent aromatic polyimide can be obtained by appropriate control of the intra-molecular charge-transfer effects between the diamine and dianhydride moieties.
The combination with MnO <sub>2</sub> nanoparticles in carbon matrix, the carbon foam exhibit absorption dominating specific EMI shielding value of −150 dB cm <sup>3</sup> g <sup>−1</sup> with high strength of 7.8 MPa.
The composition-controlled CaZnOS:0.03Ce <sup>3+</sup> ,0.03Na <sup>+</sup> ,0.03Mn <sup>2+</sup> phosphors have been investigated as single-component white-light emission components for white LEDs.
The position of activator ions in the lattice has a fundamental effect on the luminescent properties of phosphors.
This study compared the solubility of starch (G50) and microcrystalline cellulose (MCC) in an ionic liquid (IL), 1-ethyl-3-methylimidazolium acetate ([Emim][OAc]), at different temperatures. From SAXS and WAXS analysis, polysaccharides could be totally dissolved in [Emim][OAc]. Fourier-transform infrared (FTIR) spectr…
Electrospun polyaniline–polyethylene oxide nanofibers are directly written on a flexible substrate and utilized for room temperature sensing of hydrogen sulfide.
Heterometallo-supramolecular polymers with Pt( <sc>ii</sc> ) and Fe( <sc>ii</sc> ) ions introduced alternately were prepared by the 1 : 1 complexation of Fe( <sc>ii</sc> ) ions with <italic>cis</italic> - or <italic>trans</italic> -conformational organo-Pt( <sc>ii</sc> ) ligands.
We revisited and investigated a layer-structured thermoelectric material AgCrSe2, which has an extremely low thermal conductivity. After using both differential scanning calorimetry and a comparative laser flash method, we realized that the specific heat of this material, the main contributor to the reported low therm…
Herein, we present the direct modification of glucose, an abundant and inexpensive sugar molecule, to produce new sustainable and functional polymers.
Quasi low-dimensional structures are abundant among known thermoelectric materials, primarily because of their low lattice thermal conductivities. In this work, 427 known binary quasi-2D structures in 272 different chemistries are assessed for their thermoelectric performance and candidate thermoelectrics are proposed.
Hierarchically ordered mesoporous carbon/graphene (OMC/G) composites have been fabricated by means of a solvent-evaporation-induced self-assembly (EISA) method. The structures of these composites are characterized by X-ray diffraction, transmission electron microscopy, Raman spectroscopy and nitrogen adsorption-desorp…
The effects of various reaction parameters on the synthesis of silylated montmorillonites and several applications of these inorganic–organic layered materials are briefly overviewed in this review.
