Abstract A three‐dimensional carbon‐coated SnO2/reduced graphene oxide (SnO2/RGO/C) foam has been prepared by using glucose as the carbon source and cross‐linking agent through a one‐step hydrothermal process followed by freeze drying. The foam, as a free‐standing anode for lithium‐ion batteries, exhibits a large capa…
Antibody-directed chemotherapy (ADC) offers an advantage over conventional chemotherapy because it provides antibody-directed targeting, with resultant improvement in therapeutic efficacy and reduced toxicity. Despite extensive research, with notable exceptions, broad clinical application of ADC remains elusive; major…
Current strategies of bilayer technology have been aimed mainly at the enhancement of bioactivity, mechanical property and corrosion resistance. In the present investigation, the electropolymerization of poly(3,4-ethylenedioxypyrrole-co-3,4-ethylenedioxythiophene) (P(EDOP-co-EDOT)) with various feed ratios of EDOP/EDO…
The efficiency of thin-film organic photovoltaic (OPV) devices relies heavily upon the transport of excitons to type-II heterojunction interfaces, where there is sufficient driving force for exciton dissociation and ultimately the formation of charge carriers. Semiconducting single-walled carbon nanotubes (SWCNTs) are…
Disiloxanes possessing a silicon-oxygen linkage are important as frameworks for functional materials and coupling partners for Hiyama-type cross coupling. We found that disiloxanes were effectively constructed of hydrosilanes catalyzed by gold on carbon in water as the solvent and oxidant in association with the emiss…
In this work, CO2 -breathing induced reversible activation of mechanophore within microgels is reported. The microgels are prepared through soap-free emulsion polymerization of CO2 -switchable monomer 2-(diethylamino)ethyl-methacrylate, using spiropyran (SP) based mechanophore MA-SP-MA as cross-linker. The microgels c…
This study aims at physicochemical properties of thermo- and pH/CO2 -responsive cyclic homopolymers. Three examples of cyclic poly(2-(dimethylamino)ethyl methacrylate)s (PDMAs) are synthesized by combining the reversible addition-fragmentation chain transfer process and the Diels-Alder ring-closure reaction. After cyc…
Stationary long pulse plasma of high electron temperature was produced on EAST for the first time through an integrated control of plasma shape, divertor heat flux, particle exhaust, wall conditioning, impurity management, and the coupling of multiple heating and current drive power. A discharge with a lower single nu…
Abstract An attractive strategy to improve the performance of water oxidation catalysts would be to anchor a homogeneous molecular catalyst onto a heterogeneous solid surface to create a hybrid catalyst. The idea of this combined system is to take advantage of the individual properties of each of the two catalyst comp…
Adsorption and desorption of a North Sea crude oil to silica and calcium carbonate surfaces were studied by a quartz crystal microbalance, while the bare surfaces and adsorbed oil layers were characterized by atomic force microscopy and contact angle measurements. Water contact angles were measured on the bare surface…
A novel rotary state of the art active magnetic regenerator refrigeration prototype was used in an experimental investigation with special focus on efficiency. Based on an applied cooling load, measured shaft power, and pumping power applied to the active magnetic regenerator, a maximum second-law efficiency of 18% wa…
UNLABELLED: Bacteria play important roles in mineral weathering, soil formation, and element cycling. However, little is known about the interaction between silicate minerals and rhizobia. In this study, Rhizobium yantingense H66 (a novel mineral-weathering rhizobium) and Rhizobium etli CFN42 were compared with respec…
Combination of antiangiogenesis and chemotherapy holds vast promise for effective inhibition of tumor proliferation and invasion. Herein, a multifunctional self-assembled nanosystem consisting of amphiphilic c(RGDyK)-functionalized low-molecular-weight heparin-gambogic acid conjugate (cRHG) is developed, using c(RGDyK…
The effects of intramolecular hydrogen-bonding on the fluorescence behavior of three derivatives of 6-propionyl-2-dimethylaminonaphthalene are reported. The H-bonding effects are revealed through comparisons with corresponding reference compounds in which the H-bond-donating hydroxyl groups are replaced with methoxy g…
Abstract Herein, we synthesize a nanoporous N‐doped graphenic carbon with high surface area and a higher graphenization/graphitic degree by further developing the metallothermic reduction of gaseous CO2 by adding N2 into the gas flow. The N‐doped nanoporous carbon is composed of both a highly porous graphenic and non‐…
Abstract Macroporous Nb2O5 (MP‐Nb2O5) has been synthesized using dispersed polystyrene microspheres (PS) as template followed by annealing in air. The structural characterization showed that the diameters of the macropores are around 200 nm and the average particle size of the composition is 20–50 nm. XPS revealed the…
A new computational framework for systematic and optimal alloy design is introduced. It is based on a multi-objective genetic algorithm which allows (i) the screening of vast compositional ranges and (ii) the optimisation of the performance of novel alloys. Alloys performance is evaluated on the basis of their predict…
INTRODUCTION: Polyamidoamine dendrimer nanoparticles (~ 4 nanometers) are inert polymers that can be linked to biologically active compounds. These dendrimers selectively target and accumulate in inflammatory cells upon systemic administration. Dendrimer-linked compounds enable sustained release of therapeutic compoun…
This study reports how extracellular matrix (ECM) ligand self-assembly on biomaterial surfaces and the resulting nanoscale architecture can drive stem cell behavior. To isolate the biological effects of surface wettability on protein deposition, folding, and ligand activity, a polydimethylsiloxane (PDMS)-based platfor…
Abstract Development of a photosensitizing system that can reversibly control the generation of singlet oxygen (1O2) is of great interest for photodynamic therapy (PDT). Recently several photosensitizer–photochromic‐switch dyads were reported as a potential means of the 1O2 control in PDT. However, the delivery of suc…
