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. …”

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. …”
