Luminescent triarylborane homo and block copolymers with well-defined chain architectures were synthesized via reversible addition-fragmentation chain transfer polymerization of a vinyl-functionalized borane monomer. The Lewis acid properties of the polymers were exploited in the luminescent detection of fluoride ions…
Artificial skin, which mimics the functions of natural skin, will be very important in the future for robots used by humans in daily life. However, combining skin's pressure sensitivity and mechanical self-healing properties in a man-made material remains a challenging task. Here, we show that graphene and polymers ca…
Pulsed laser ablation has proved its reliability for the synthesis of nano-particles and nano-structured materials, including metastable phases and complex stoichiometries. The possible nucleation of the nanoparticles in the gas phase and their growth has been little investigated, due to the difficulty of following th…
Chemical doping of nitrogen into graphene can significantly enhance the reversible capacity and cyclic stability of the graphene-based lithium ion battery (LIB) anodes, and first principles calculations based on density functional theory suggested that pyridinic-N shows stronger binding with Li with reduced energy bar…
Evidence for metal–carbon orbital mixing in thorocene and uranocene was determined from DFT calculations and carbon K-edge X-ray absorption spectra (XAS) collected with a scanning transmission X-ray microscope (STXM). Both the experimental and computational results showed that the 5f orbitals engaged in significant δ-…
Abstract Ce‐doped Lu 3 Al 5 O 12 optical ceramics co‐doped with Mg 2+ are fabricated by solid‐state reaction method and further optimized by an air‐annealing process. Mg 2+ co‐doping leads to a significant decrease of thermoluminescence intensity above room temperature and an increase of scintillation light yield (LY)…
In this review we discuss recent research on driving self-assembly of magnetic particle suspensions subjected to alternating magnetic fields. The variety of structures and effects that can be induced in such systems is remarkably broad due to the large number of variables involved. The alternating field can be uniaxia…
A reduced PRF mechanism was proposed for combustion simulations of PRF and diesel/gasoline fuels based on the latest LLNL mechanism. The reduced PRF mechanism consists of 73 species and 296 reactions. The major reaction pathways of the detailed mechanism were mostly retained in the reduced mechanism, which ensures its…
In Mott insulators with the ${t}_{2g}^{4}$ electronic configuration such as of ${\mathrm{Re}}^{3+}$, ${\mathrm{Ru}}^{4+}$, ${\mathrm{Os}}^{4+}$, and ${\mathrm{Ir}}^{5+}$ ions, spin-orbit coupling dictates a Van Vleck--type nonmagnetic ground state with an angular momentum $J=0$, and the magnetic response is governed b…
The properties of nitrogen centres acting either as hydrogen-bond or Brønsted acceptors in solid molecular acid-base complexes have been probed by N 1s X-ray photoelectron spectroscopy (XPS) as well as (15)N solid-state nuclear magnetic resonance (ssNMR) spectroscopy and are interpreted with reference to local crystal…
Interest in utilizing biorenewable feedstocks to produce fuels and chemicals has risen greatly in the past decade due to the economic, political and environmental concerns associated with diminishing petroleum reserves. A fundamental challenge lying ahead in the development of efficient processes to utilize biomass fe…
Degradation of perovskite has been a big problem in all-solid-state perovskite solar cells, although many researchers mainly focus on the high efficiency of these solar cells. This paper studies the stability of CH3NH3PbI3 films and finds that CH3NH3PbI3 is sensitive to moisture. The degradation reaction is proposed a…

Five tetrafluoro substituted metallophthalocyanines(FePcF4, CoPcF4, NiPcF4, CuPcF4 and ZnPcF4) were synthesised and characterised by Fourier transform infrared spectroscopy and mass spectrometry. The optical and thermal properties of these compounds were investigated by ultraviolet–visible (UV-vis), photoluminescence…
Modelling is a widely used tool to facilitate the evaluation of disease management. The interest of epidemiological models lies in their ability to explore hypothetical scenarios and provide decision makers with evidence to anticipate the consequences of disease incursion and impact of intervention strategies. All mod…
Doping of Mn and N in ZnO results in p type ZnO. In the present study, hydrothermal method has been used to prepare Mn, N codoped ZnO nanorod thin films with hexagonal wurtzite structure. X-ray diffraction and X-ray photoelectron spectroscopy studies indicate that divalent Mn2+ ions are incorporated into ZnO lattice.…
Expressions that relates the dissipated electric energy between the right-handed (conventional material) and the left-handed (electromagnetic metamaterial) systems are obtained from generic spectra for external electric and magnetic perturbations. Also when the perturbations are electromagnetic waves. In this case, an…
The self-assembly of a semi-flexible aminotriazine-based bis-methylpyridine ligand, N(2),N(2)-dibenzyl-N(4),N(6)-di(pyridylmethyl)-1,3,5-triazine-2,4,6-triamine (H2L), with NiCl2 and NiBr2 afforded two new nickel(II) clusters, (H2NMe2)2[Ni5(OH)2(H2L)2Cl10] (1) and [Ni6(OH)2(H2L)2Br10(THF)2] (2) showing a high spin gro…
For practical use of an under-sodium viewer, the behavior of sodium wetting is investigated by modeling the reactive and non-reactive wetting of metallic-plated steels by liquid sodium to simulate sodium wetting. The non-reactive wetting simulation results showed good agreement with Tanner's law, in which the time dep…
Gaskets made of acrylonitrile butadiene rubber (NBR) coating and metal plate were one of the classified seals used in automotive engine. In the present study, NBR foam–metal composite gaskets were prepared by liquid NBR overlain metal plate. The foam coating was thinner and more uniform compared with solid rubber form…
