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

“…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. …”

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

“…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.…”

Chiral Modes at Exceptional Points in Exciton-Polariton Quantum Fluids by Gao, T., Li, G., Estrecho, E., Liew, Timothy Chi Hin, Comber-Todd, D., Nalitov, A., Steger, M., West, K., Pfeiffer, L., Snoke, D. W., Kavokin, A. V., Truscott, A. G., Ostrovskaya, E. A.

“…In particular, a vortex is generated by driving two dipole modes of the non-Hermitian ring resonator into degeneracy. Transition through the exceptional point in the space of the system’s parameters is enabled by precise manipulation of real and imaginary parts of the closed-wall potential forming the resonator. …”

Synthesis of some selenacrown ethers and the thermodynamic origin of their complexation with C60 by Liu, Yu, Han, Jian Rong, Zhao, Yanli, Zhang, Heng Yi, Duan, Zhong Yu

“…The obtained Ks values together with that reported for dicyclohexano-24-crown-8 (5) reveal that, the more the heteroatom numbers in crown ether ring are, and the larger the cavity sizes of crown ethers are, the higher the Ks values for complexation with C60 are. …”

Experimental and numerical studies of S960 ultra-high strength steel welded I-section columns by Su, Andi, Liang, Yating, Zhao, Ou

“…A testing programme, including initial geometric imperfection measurements and ten pin-ended column tests, was conducted. The testing programme was accompanied by a numerical modelling programme, where finite element models were firstly developed and validated against the test results, and then employed to perform parametric studies to generate further numerical data. …”

Synthesis of α-methylene-δ-valerolactone and its selective polymerization from a product mixture for concurrent separation and polymer production by Khechfe, Alexander A, Eckstrom, Francesca D, Chokkapu, Eswara Rao, Baston, Lucas A, Liu, Bowei, Chen, Eugene Y-X, Román-Leshkov, Yuriy

“…Using a model mixture of 30 wt% of MVL in DVL, vinyl-addition polymerization converted MVL to the corresponding vinyl polymer (PMVL)VAP in 98% yield, while DVL was recovered in 96% yield by distillation. Alternatively, ring-opening polymerization of the same mixture resulted in a DVL/MVL copolyester and separatable vinyl homopolymer P(MVL)VAP.…”

Biochemical Analysis of Poly(ethylene terephthalate) Film Degradation Kinetics of Engineered IsPETase Variants by Zhong-Johnson, En Ze Linda

“…I developed a kinetic assay based on spectrophotometric measurements of UVabsorbance of the products in the reaction supernatant, as degradation products harboring the benzene ring will absorb between 240-280 nm. The method was found to be reliable to obtain relative measurements of initial reaction rates but cannot be used to determine the absolute concentration of products in the supernatant. …”

Two kinds of phase transition in photonic systems with application to optical isolation by Zhou, Xin

“…We study three representative designs: (i) a waveguide array implementing a nonlinear 1D Su-Schrieffer-Heeger model, (ii) a waveguide array implementing a nonlinear 2D Haldane model, and (iii) a 2D lattice of coupled-ring waveguides. In the first two cases, we find a correspondence between the topological transition of the underlying linear lattice and the power threshold of the transmittance, and show that the transmission behavior is attributable to the emergence of a self-induced topological soliton. …”

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

“…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. …”
