Indefinite metamaterials for optical applications by Bisht, Ankit

“…Using full-wave Finite-difference time-domain (FDTD) simulations with diffraction limited trimer, quadrumer and ringed objects etched on thin perfect electric conductor (PEC) films, we show that the hyperlens model can achieve magnification factors of up to 10X in the far-field (~4.5λ from object’s surface) under a light source with a wavelength of 1 μm, with successful resolution down to 220 nm (~λ/5). …”

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. …”

Controlling selectivity in the reductive activation of CO2 by mixed sandwich uranium(iii) complexes by Tsoureas, N, Castro, L, Kilpatrick, A, Cloke, FGN, Maron, L

“…The nature of the R group on the cyclopentadienyl ring in the former has a significant effect on the outcome of CO2 activation: when R = Me, the products are the bridging oxo complex {U[η8-C8H6(1,4-SiMe3)2](η5-CpMe5)}2(μ-O) and the bridging oxalate complex {U[η8-C8H6(1,4-SiMe3)2](η5-CpMe5)}2(μ-η2:η2-C2O4); for R = Et or iPr, bridging carbonate {U[η8-C8H6(1,4-SiMe3)2](η5-CpMe4R)}2(μ-η1:η2-CO3) and bridging oxalate complexes {U[η8-C8H6(1,4-SiMe3)2](η5-CpMe4R)}2(μ-η2:η2-C2O4) are formed in both cases; and when R = tBu the sole product is the bridging carbonate complex {U[η8-C8H6(1,4-SiMe3)2](η5-CpMe4tBu)}2(μ-η1:η2-CO3). …”

Bondi mass with a cosmological constant by Saw, Vee-Liem

“…Furthermore, with MΛ=MB, we show that for purely quadrupole gravitational waves given off by the isolated system (i.e., when the “Bondi news” σo comprises only the l=2 components of the spherical harmonics with spin-weight 2) the energy carried away is manifestly positive definite for the Λ>0 case. …”

Design and development of a biopolymer microfiber fabrication device by Yap, Yi-Liang.

“…Molten polymer within a holding cup with a tiny orifice below is drawn by a needle and stuck onto a spinning mandrel for collection. As the melt is pulled from the orifice, extensional flow causes the thinning in the melt diameter and the atmosphere cools the melt down into a fiber before it is collected on the mandrel. …”
