Ultrafast Dynamics of Spin Current and Electron Temperature in Spintronic Terahertz Emitters
Advanced Science, EarlyView.This work quantifies optical‐pump‐induced THz transmission variations to reveal electron and lattice temperature dynamics and presents time‐resolved THz spectral maps for sub‐picosecond analysis. A 63 ± 8 fs time lag between THz emission and laser excitation is identified, serving as an intrinsic parameter limiting the upper frequency of spintronic THz

The Emperor's tales on the Great Palace mosaic of Constantinople : some iconographic reconstructions [PDF]
, 2015 This study aims to emphasize how in Constantinople the notions of ‘rule’ and ‘recreation’ were often strongly associated. A paradigmatic example is indeed constituted by the mosaic floor of profane subjects discovered in the area of the Great Palace of ...

Advanced Science, EarlyView.A multifunctional tantalum incorporation strategy enables simultaneous tuning of carrier concentration, mitigation of grain‐boundary scattering, and enhanced phonon scattering in Mg3(Sb,Bi)2. These synergistic effects markedly improve carrier mobility and suppress lattice thermal conductivity, yielding both high material zT and high module conversion ...

The creation of ruled surfaces in a hall of mirrors
Abstract: Atwo-mirror laser scanner, utilising rotating mirrors to direct a fixed laser, generates a two-degree-of-freedom line set: a two-mirror congruence. Thiscongruence, formedbytherulingsofcoaxialhyperboloids, enablesthe creation of diverse ruled surfaces. We present a user-friendly application for interactive mirror manipulation, allowing dynamic

Imaging Electric Polarization Switching in Multilayer Graphene
Advanced Science, EarlyView.Domain wall sliding‐induced electric polarization switching is directly observed for the first time in multilayer graphene, enabled by a novel optical readout method. The polarization switching is realized upon application of global and local electric fields, and mechanical forces between neighboring polar domains of opposite out‐of‐plane polarizations

Advanced Science, EarlyView.Strong‐yet‐ductile precipitation‐hardening alloys require novel microstructural complexity of precipitates in particularly at cryogenic condition, to constantly impart strain hardening of hard‐and‐brittle precipitates. The present work creates innovative structurally complex precipitates assembled with dispersed nanocores and a chemical‐heterogeneity ...

Advanced Science, EarlyView.A fully compensated synthetic antiferromagnet (SAF) multilayer exhibits a uniform state at zero field, without skyrmions. We use a SAF bias system to provide RKKY‐mediated exchange bias to the SAF multilayer, promoting zero‐field skyrmion stabilization and polarity control.

Advanced Science, EarlyView.Thermally activated LiHCOO induces in situ pseudo‐halide diffusion, promoting buried interface strain release and perovskite crystallization. The monoclinic LiHCOO phase forms an open framework structure that enhances HCOO− diffusion and drives interfacial restructuring.
