Proposals for superconductivity emerging from correlated electrons in the doped Hubbard model on the honeycomb lattice range from chiral $d+id$ singlet to $p+ip$ triplet pairing, depending on the considered range of doping and interaction strength, as well as the approach used to analyze the pairing instabilities. Her…
A series of homologous dendronized polymers (DPs) with generations ( g ) 1–3 and backbone nominal degrees of polymerization ( P n ) in the range 50–3000 have been synthesized and characterized in order to investigate the g - and P n -dependent viscoelastic properties and packing of this class of densely grafted, assoc…
One of the approaches to improve our ability to characterize biologically important processes and to map out an underlying free energy landscape is to direct MD simulations to explore molecular conformational phase space faster. Intrinsically disordered systems with shallow free energy landscapes of a huge number of m…
The nature of microwave sintering cannot be explained in the past and has been generally called microwave effect. Here we show that the E-field intensification is the reason of microwave fast sintering of solid state inorganic compounds. The intensification degree varied with dielectric constant of compound, distance…
The catalytic cracking of model tar species (toluene) using sewage sludge char (SSC) was investigated. The effects of typical syngas components from municipal solid waste (MSW) gasification on toluene conversion ratio, cracking product distribution, and characteristics of the SSC catalyst were studied. Deposited coke…
Electroless nickel phosphorus (Ni–P) coatings were synthesised from an acid chloride electrolyte. The synthesised coatings were heat treated at different temperatures, and the surfaces of the heat treated coating were characterised using scanning electron microscopy and X-ray diffraction. Adhesion, wettability, hardne…
A propagation model of vector beams generated by metasurfaces based on vector diffraction theory is established theoretically and verified experimentally. Considering the Pancharatnam-Berry phase introduced by the metasurface, analytical forms of vector beams for arbitrary incident polarization and topological charge…
We introduce a coupled-layer construction to describe three-dimensional topological crystalline insulators protected by reflection symmetry. Our approach uses stacks of weakly coupled two-dimensional Chern insulators to produce topological crystalline insulators in one higher dimension, with tunable number and locatio…
The design and preparation of recyclable catalysts are of great economic and environmental importance in the chemical and medicinal industries. Immobilization of homogeneous catalysts on various in...
In the letter, we propose the design of circulators based on spoof surface plasmon polaritons (SSPP). Rather than striplines, the center conductor is replaced with a blade structure that supports the SSPP mode and exhibits a shorter wavelength and larger wave vector. To enhance the efficiency, a matching transition is…
Herein, a facile method for the preparation of organometal halide perovskite (OHP) thin films in photonic crystal morphology is presented. The OHP photonic crystal thin films with controllable porosity and thicknesses between 2 μm and 6 μm were prepared on glass, fluorine-doped tin oxide (FTO), and TiO2 substrates by…
The extractions of potassium value from feldspar via roasting and leaching route was studied with a focus on the effects of the roasting time, temperature, additives, and particle size. Sodium chloride and phosphogypsum (PG) were used as a source of chloride and calcium, respectively, and played the important role dur…
The molecular orientation and phase separation of poly(3-hexylthiophene) (P3HT) and poly[[ N,N -bis(2-octyldodecyl)-napthalene-1,4,5,8-bis(dicarboximide)-2,6-diyl]- alt -5, 5′-(2,2′-bithiophene)] (N2200) blends are investigated by in situ temperature-resolved two-dimensional grazing incidence X-ray diffraction (2D GIX…
Abstract Designing zeolites with tunable physicochemical properties can substantially impact their performance in commercial applications, such as adsorption, separations, catalysis, and drug delivery. Zeolite synthesis typically requires an organic structure‐directing agent to produce crystals with specific pore topo…
In this study, we investigated the ability of the general anesthetic propofol (PR) to form inclusion complexes with modified β-cyclodextrins, including sulfobutylether-β-cyclodextrin (SBEβCD) and hydroxypropyl-β-cyclodextrin (HPβCD). The PR/SBEβCD and PR/HPβCD complexes were prepared and characterized, and the blood–b…
Finding an efficient photosensitizer is crucial in ensuring a therapeutic effect of photodynamic treatment. Currently, screening of photosensitizers during photodynamic therapy is achieved by evaluating the total yield of singlet oxygen ( 1 O 2 ), rather than monitoring the formation dynamics of 1 O 2 . 1 O 2 -based c…
A simple nanoprecipitation method was used for preparation of stable photoactive polystyrene nanoparticles (NPs, diameter 30 ± 10 nm) from sulfonated electrospun polystyrene nanofiber membranes with encapsulated 5,10,15,20-tetraphenylporphyrin (TPP) or platinum octaethylporphyrin (Pt-OEP). The NPs prepared with TPP ha…
The ability of plasmonic structures to manipulate light well below the diffraction limit has enabled the miniaturization of a range of chipscale optoelectronic devices. Of the many emerging applications, the development of plasmon-enhanced photodetection schemes has witnessed particularly impressive progress. For such…
Abstract We report a new nonaqueous polymerization-induced self-assembly (PISA) formulation based on the reversible addition?fragmentation chain transfer (RAFT) dispersion alternating copolymerization of styrene with N-phenylmaleimide using a nonionic poly(N,N-dimethylacrylamide) stabilizer in a 50/50 w/w ethanol/meth…
Effective carbon-carbon coupling of acetic acid to form larger products while minimizing CO2 emissions is critical to achieving a step change in efficiency for the production of transportation fuels from sustainable biomass. We report the direct acylation of methylfuran with acetic acid in the presence of water, all o…
