The low solubility of nanocarbon materials (fullerenes, CNTs and graphene) has restricted their widespread commercial use.Functionalization, however, helps overcome this major limitation.Much work has been documented recently on water soluble fullerenes (FWS) in treating cancer (e.g.breast cancer), tumours, arthritis,…
We demonstrate universal non-adiabatic non-abelian holonomic single quantum gates over a geometric electron spin with phase-modulated polarized light and 93% average fidelity. This allows purely geometric rotation around an arbitrary axis by any angle defined by light polarization and phase using a degenerate three-le…
Developing temperature transferable coarse-grained (CG) models is essential for the computational prediction of polymeric glass-forming (GF) material behavior, but their dynamics are often greatly altered from those of all-atom (AA) models mainly because of the reduced fluid configurational entropy under coarse-graini…
A polyHIPE (PH) is a macroporous polymer synthesized within a high internal phase emulsion (HIPE). The high-porosity, highly interconnected, open-cell structures and the PH-swelling-driven void expansion mechanism have made PH systems of interest for liquid absorption. Usually, only hydrophobic liquids or only hydroph…
Conductive rubber composites usually suffer a large filler content and relatively low conductivity because the uniform dispersion of conductive nanofillers in rubbers is probably inhibited by the cross-link networks. However, by establishing a double-network model of cross-link and conductive networks, we found the co…
Hybrid systems based on the combination of crystalline bulk semiconductors with 2D crystals are identified as promising heterogeneous structures for new optoelectronic applications. The direct integration of III–V semiconductors on 2D materials is very attractive to make practical devices but the preservation of the i…
Abstract A fundamental understanding of the interplay between ligand‐removal kinetics and metal aggregation during the formation of platinum nanoparticles (NPs) in atomic layer deposition of Pt on TiO 2 nanopowder using trimethyl(methylcyclo‐pentadienyl)platinum(IV) as the precursor and O 2 as the coreactant is presen…
A novel copolymer, polyurethane–poly(acrylic acid) (PAA), is successfully synthesized from poly(acrylic acid) (PAA) backbone cross-linked with waterborne polyurethane (WPU). This sticky polymer, which is neutralized with 1 M KOH and then soaked in 1 M KOH (denoted as WPU-PAAK-K), provides an ionic conductivity greater…
Using water as a reaction medium to synthesize biobased monomers with high renewable carbon content for preparing biobased polymers is of great importance for environmental protection and sustainable development. Herein, a trifunctional allyl compound, tris(4-allyl-2-methoxyphenyl) phosphate (TAMPP) with 100% renewabl…
Abstract For the first time, the Raman spectra of bulk Se x Te 1‐ x glasses, 0.5 ≤ x ≤ 1.0, have been measured over the entire glass‐forming range. The spectra exhibit three broad spectral features between 150 and 300 cm −1 , attributed to Te–Te, Se–Te, and Se–Se stretching modes according to DFT simulations. The obse…
Using 31 P nuclear magnetic resonance (NMR) spectroscopy, we monitor the competition between tri- n -butylphosphine (Bu 3 P) and various amine and phosphine ligands for the surface of chloride terminated CdSe nanocrystals. Distinct 31 P NMR signals for free and bound phosphine ligands allow the surface ligand coverage…
Two different silk fibroin samples were obtained by the Na2CO3 and urea degumming methods of silk fibers in the same fiber dissolution system, respectively. The molecular weight and viscosity of the fibroin samples were analyzed by the methods of SDS-PAGE, rheological, and etc. Then, different silk fibroin membranes (…
Here we discuss the similarities and differences in anti-plane surface wave propagation in an elastic half-space within the framework of the theories of Gurtin–Murdoch surface elasticity and Toupin–Mindlin strain-gradient elasticity. The qualitative behaviour of the dispersion curves and the decay of the obtained solu…
As a new kind of two-dimensional carbon allotrope, graphdiyne (GDY) consists of sp- and sp 2 -hybridized carbon atoms and has recently been used for developing highly efficient photocatalytic systems because of its unique properties. In this study, we find that GDY can form a Pickering emulsion with silver phosphate (…
We report the synthesis of a semiquinoid-bridged single-chain magnet, as generated through a thermally induced metal–ligand electron transfer. Reaction of FeCl 3 with 2,5-dichloro-3,6-dihydroxy-1,4-benzoquinone (LH 2 ) in the presence of (NMe 4 )Cl gave the compound (NMe 4 ) 2 [LFeCl 2 ]. Together, variable-temperatur…
Realizing and manipulating a fine dispersion of silica nanoparticles (NPs) in the polymer matrix is always a great challenge. In this work, we first successfully synthesized N, N'-bis[3-(triethoxysilyl)propyl-isopropanol]-propane-1,3-diamine (TSPD), which was a new interface modifier, aiming to promote the dispersion…
Plasmonic metasurfaces have attracted much attention in recent years owing to many promising prospects of applications such as polarization switching, local electric field enhancement (FE), near-perfect absorption, sensing, slow-light devices, and nanoantennas. However, many problems in these applications, like only g…
We model the operation and readout sensitivity of two current-modulated magnetoplasmonic devices which exploit spin Hall effect-like behavior as a function of their device and material parameters. In both devices, current pulses are applied to an electrically-isolated stack, containing an active layer (either a metal…
THz Time-Resolved Photoconductivity is used to probe carrier dynamics in the dilute III-V nitride GaP0.49As0.47N0.036. In these measurements a femtosecond optical pump-pulse excites electron-hole pairs, and a delayed THz pulse measures the change in conductivity. We find the photoconductivity is dominated by localized…
Quasiparticle excitations beyond Dirac-Weyl-Majorana classification can appear in lattice systems due to the less symmetry constraint compared with Poincaré symmetry in high energy physics. In particular, fermions with an integer spin can appear in a variety of lattices. Here, we show that two-dimensional spin-1 fermi…
