Rapid Solidification Brings Ultralow Thermal Conductivity and Superior Thermoelectric Performance for Intrinsic GeTe Alloy

Advanced Science, EarlyView.
Rapid solidification with glass fluxing is first applied to the intrinsic GeTe alloy and achieves large undercooling within 2 h. This enables partial retention of the high‐temperature cubic phase at room temperature and forms a crystallographically oriented α+β dual‐phase structure and a hierarchical defect network.

Prepolymerization Enables On‐Demand Viscosity Tuning for Xolography of Soft Hydrogels

Advanced Science, EarlyView.
A facile in situ prepolymerization strategy enables on‐demand viscosity tuning across three orders of magnitude without external thickeners, transforming low‐viscosity resins into printable formulations for Xolography. The approach suppresses sedimentation, lowers curing dose, enables high‐fidelity support‐free fabrication, and produces advanced ...

Approximation of optimal control for functional-differential equations by optimal control of equations without delay in infinite-dimensional spaces

Researches in Mathematics
The problem of optimal control for a functional-differential equation of parabolic type in a Banach space is studied. An approximation procedure is proposed, which consists of replacing the original equation by the system of parabolic equations without ...

Laser‐Induced Rashba Spin‐Orbit Torques in Multiferroic Semiconductor (Ge,Mn)Te

Advanced Science, EarlyView.
Femtosecond optical excitation generates two distinct effective spin–orbit torques in the multiferroic semiconductor (Ge,Mn)Te. Photoinduced holes drive coherent magnetization precession through a subpicosecond shift of the easy axis, while changes in ferroelectric sublattice displacements modify magnetic ordering via the Rashba interaction.

Heavy‐Atom Tunneling at Room Temperature Revealed by Instanton Theory

Angewandte Chemie, EarlyView.
Usually, tunneling does not play a significant role in chemical reactions except at low temperature, especially when heavy atoms are involved. However, using nonadiabatic instanton theory we find that heavy‐atom tunneling dominates the reaction mechanism for spin‐forbidden processes in the synthesis of strained organic molecules even at room ...

Hybrid Semi‐Transparent Perovskite‐Photovoltaics and Concentrated Solar‐Thermal Harvesting Collectors

Advanced Science, EarlyView.
A hybrid semi‐transparent perovskite‐photovoltaic and concentrating solar‐thermal collector is developed to spectrally split sunlight for simultaneous electricity and heat generation. The design achieves thermal decoupling between the photovoltaic and thermal components, offering a promising route for efficient co‐harvesting of solar electricity and ...

Coexistence of Large Nernst Effect and Axis‐Dependent Conduction Polarity in Semimetal MoSi2

Advanced Electronic Materials, EarlyView.
MoSi2${\rm MoSi}_2$ is a rare material in which axis‐dependent conduction polarity (ADCP) and a large ordinary Nernst effect (ONE) coexist. The pronounced ONE (199μVK−1$199\,\umu \mathrm {V}\,\mathrm {K}^{-1}$) originates from nearly perfect carrier compensation, high mobility, and likely phonon drag, while ADCP arises from mixed‐dimensionality of the ...

Extrapolation of solvability of the parabolic L^p Neumann problem on bounded Lipschitz cylinders

Electronic Journal of Differential Equations
A recent result of the first author with Li and Pipher established the extrapolation of solvability of the $L^p$ parabolic Neumann problem on unbounded graph domains of the form $\Omega=\{(x',x_n):x_n>\phi(x')\}\times\mathbb{R}$, where $\phi:\mathbb{R ...

Reveal Non‐Uniform Passivation on Lithium Metal Anode With Operando Spectroscopic Ellipsometry

Advanced Energy Materials, EarlyView.
In‐operando spectroscopic ellipsometry reveals how nucleation and crystallographic orientation govern the non‐uniform growth of native passivation films on lithium metal. Time‐resolved thickness mapping captures island formation and coalescence, while orientation‐dependent measurements show that the equilibrium film on Li(110) is approximately half as ...

A Computational Approach for Biomimetic Design of Liver‐On‐A‐Chip

Advanced Intelligent Discovery, EarlyView.
A biomimetic liver‐on‐a‐chip with antiparallel perfusion was designed using COMSOL‐guided simulation to replicate hepatic acinus transport. Full‐scale modelling revealed diffusion‐dominated, length‐dependent nutrient gradients and low‐shear conditions.
