A Pt@TNT catalyst with Pt nanoparticles entrapped in titanate nanotubes (TNT) was prepared by hydrophobic modification of the exterior surface of the TNT and impregnation with hexachloroplatinic acid (H2PtCl6) aqueous solution. The catalyst's enhanced activity towards the hydrogenation of phenol (as high as ∼3200 gphe…
H NMR, FTIR, DSC, and WAXD. The chain composition, melting point and crystallinity of the PBISI copolyesters can be tuned continuously by changing the content of isosorbide. The crosslinked copolyester is demonstrated to be a promising shape memory polymer (SMP) with excellent shape memory properties including shape f…
We report a novel RuO2–NPG//Co(OH)2–NPG asymmetric supercapacitor with a high specific capacitance and a wide potential window in which bifunctional nanoporous gold is used as both the highly conductive supports of the pseudocapacitive oxides and the 3D current collectors in the device. The RuO2–NPG and Co(OH)2–NPG el…
Composition control in multi-component low molecular weight hydrogels can be achieved, using an electrochemically triggered approach.
The particles that can reversibly switch shape in response to an environmental stimulus are preferable for controlling the performance of drug carriers. In this work, we present a facile strategy towards the design and fabrication of polymer particles that can reversibly switch their shape on the basis of a biocompati…
In-plane mesoporous graphene oxide (GO) sheets were prepared by a re-oxidation process and subsequently assembled into lamellar membranes. The in-plane pores significantly shortened the mass transport paths, resulting in 2–3 times higher water permeance than that of the pristine GO membrane, but continued to reject 3…
Stiff yet flexible and strong transparent film materials mimicking the structure of crustacean exoskeletons were obtained from calcium carbonate and cellulose. These biobased materials have the composite structure of a three-dimensional nanoscale network of surface-carboxylated crystalline cellulose incorporated into…
We have synthesized and characterized a water-soluble gold(III) corrole (1-Au) that is highly toxic to cisplatin-resistant cancer cells. Relative to its 1-Ga analogue, axial ligands bind only weakly to 1-Au, which likely accounts for its lower affinity for human serum albumin (HSA). We suggest that the cytotoxicity of…
One of the obvious shortcomings of bio-based shape memory polyurethanes (Bio-SMPUs), which usually use natural oil based polyols as the soft segment, is their low mechanical strength because the long dangling chains (six to eight carbons) in these polyols prevent the Bio-SMPUs from deep micro-phase separation, and con…
Synthesis of Organic Nanoparticles and their Applications in Drug Delivery and Food Nanotechnology: A Review Organic nanoparticles, nanocrystals and nanobeads are of major interest in material and life sciences. Biopolymer nanoparticles are offering numerous advantages that embrace the simplicity of their preparation…
WO <sub>3</sub> nanoplates derived from NiWO <sub>4</sub> were found to have the highest concentration of oxygen vacancy, narrowest band gap, longest electron–hole recombination time, and in turn the highest rate of photodegradation of azo dye methylene blue.
Al content dependent defect concentration (oxygen vacancies) and Rhodamine 6G dye photodecomposition activity of sol–gel nanostructured ZnO thin films.
3D ordered nanocrystalline nanoporous NiMoO <sub>4</sub> with high surface area and bimodal pore size distribution has been synthesized by nanocasting from mesoporous silica KIT-6, and applied as high-performance supercapacitor electrode material.
Here, we report modified carbon spheres (CS) as a high energy and power density flowable electrode for use in electrochemical flow capacitors – a new energy storage concept proposed by our group. Activated CS with high specific surface area (SSA) of 1157 m2 g−1 were obtained by CO2 activation. The electrochemical perf…
A novel naphthyl-based phthalonitrile monomer, 1,6-bis(3,4-dicyanophenoxy) naphthalene (1,6-BDCN), was prepared, and the phthalonitrile resin was cured with 4,4′-diaminodiphenyl ether (ODA) via two steps, namely, preparation of prepolymer and postcuring prepolymer at elevated temperatures. The 1,6-BDCN polymer might f…
Novel core–shell structured Fe <sub>3</sub> O <sub>4</sub> @C@Ni–Al LDH microspheres were prepared by a hydrothermal method following a facile <italic>in situ</italic> growth process. The as-prepared product exhibits high pseudocapacity (767.6 F g <sup>−1</sup> ), good rate capability, and remarkable cycling stability…
This study describes the preparation, characterization, and controlled release of a streptomycin-chitosan-magnetic nanoparticle-based antibiotic in an effort to improve the treatment of bacterial infections. Specifically, chitosan-magnetic nanoparticles were synthesized by an incorporation method and were characterize…
A high enantiomer-selectivity for the polymerization of rac-lactide was achieved using chiral binaphthol-derived monophosphoric acids as organocatalysts. During the polymerization, d-lactide (DLA) preferentially polymerized via kinetic resolution with the maximum selectivity factor (kD/kL) of 28.3. The selective polym…
