    Controlling Cherenkov angles with resonance transition radiation by Lin, Xiao, Easo, Sajan, Shen, Yichen, Chen, Hongsheng, Zhang, Baile, Joannopoulos, John D., Soljačić, Marin, Kaminer, Ido

    Published 2019
    “…However, since the Cherenkov angle depends only on the material’s permittivity, the material unavoidably sets a fundamental limit to the momentum coverage and sensitivity of Cherenkov detectors. For example, ring-imaging Cherenkov detectors must employ materials transparent to the frequency of interest as well as possessing permittivities close to unity to identify particles in the multi-gigaelectronvolt range, and thus are often limited to large gas chambers. …”

    The effect of bonding structure of diamond like carbon (DLC) film with surface nickel coating upon laser annealing by Xu, Naiyun, Tsang, Siu Hon, Tan, Chong Wei, Teo, Hang Tong, Wang, Xincai, Tay, Beng Kang

    Published 2021
    “…The Raman spectra shows more pronounced change for a-C films with Ni coating than those without Ni coating upon laser annealing, and the Raman features also suggest that the Ni surface coating can enhance formation of the six-ring graphitic-like sp2 ordering. Electrical measurement shows a low resistive characteristic for both set of films due to laser induced conducting sp2 clusters formation.…”

    Transient dynamics of a one-dimensional Holstein polaron under the influence of an external electric field by Huang, Zhongkai, Chen, Lipeng, Zhou, Nengji, Zhao, Yang

    Published 2017
    “…In particular, at variance with the case of an infinite linear chain, no steady state is found in a finite-sized ring within the anti-adiabatic regime. For strong diagonal coupling, the multi-math formula Anstaz is found to be highly accurate, and the phonon confinement gives rise to exciton localization and decay of the Bloch oscillations.…”

    C–H activation and nucleophilic substitution in a photochemically generated high valent iron complex by Lim, Jia Hui, Engelmann, Xenia, Corby, Sacha, Ganguly, Rakesh, Ray, Kallol, Soo, Han Sen

    Published 2018
    “…The presence of labile Cl− or Br− results in a ligand-based oxidation and stabilisation of a radical-cationic (TAML˙+)FeIII complex, which subsequently leads to unprecedented C–H activation followed by nucleophilic substitution on the TAML aryl ring. In contrast, exogenous cyanide culminates in metal-based oxidation, yielding the first example of a crystallographically characterised S = 1 [(TAML)FeIV(CN)2]2− species. …”
