Lithium and Vanadium Intercalation into Bilayer V2Se2O: Ferrimagnetic–Ferroelastic Multiferroics and Anomalous and Spin Transport

Advanced Science, EarlyView.
Li‐ and V‐intercalated V2Se2O bilayers possess intralayer ferrimagnetic and interlayer ferromagnetic orders, alongside ferroelasticity, in‐plane uniaxial magnetic anisotropy, half‐metal/enhanced spin splitting, the anomalous Hall effect, giant magnetoresistance, tunneling magnetoresistance, near‐perfect spin filtering effect, spin Seebeck effect, and ...

Boosting Nanofiltration Membrane Selectivity via Amine‐Polymer Additive Engineering for Efficient Lithium Extraction From Brine

Advanced Science, EarlyView.
A diffusion‐controlled interfacial polymerization strategy incorporating poly(allylamine) (PAA) into piperazine (PIP) solution enables precise tuning of amine monomer diffusion and polyamide (PA) network formation with trimesoyl chloride (TMC). The resulting nanofiltration membranes exhibit crumpled morphology, appropriate surface charge, and enhanced ...

Topologically Protected Negative Entanglement

Advanced Science, EarlyView.
It is revealed that topological flat‐band edge states can lead to robust unconventional negative entanglement entropy scaling. This arises from a new mechanism of non‐Hermitian critical skin compression (nHCSC), which strongly “compresses” quantum information beyond flat‐band degeneracy.

Coordinated Active and Reactive Power Control of VSC-HVDC for Enhancing Static Voltage Stability in AC/DC Systems

Energies
When conducting research on the static voltage stability of AC/DC systems with voltage source converter-high voltage direct current (VSC-HVDC) transmission lines, the focus is often given to reactive power control, neglecting the potential from active ...

A Clarification on Quantum‐Metric‐Induced Nonlinear Transport

Advanced Science, EarlyView.
How does the quantum metric truly govern the nonlinear transport? The longstanding theoretical discrepancies are resolved in quantum‐metric‐induced nonlinear transport and the correct intrinsic nonlinear conductivity is identified. Furthermore, a toy model is engineered to suppress the competing effects, uniquely highlighting the role of quantum metric

Lower bounds of the minimum eigenvalue for $M$-matrices

, 2017
Some monotone increasing sequences of the lower bounds for the minimum eigenvalue of $M$-matrices are given. It is proved that these sequences are convergent and improve some existing results. Numerical examples show that these sequences are more accurate than some existing results and could reach the true value of the minimum eigenvalue in some cases.

A Versatile Three Dimensional Traction Force Microscopy Framework for Uncovering the Mechanics of Bio‐Adhesion

Advanced Science, EarlyView.
This study introduces a versatile platform for quantifying three dimensional traction forces at bio‐adhesive interfaces. Integrating in situ stereo‐digital image correlation with finite element simulations allows for precise measurement of microscale displacements and traction forces in both dry and wet conditions.
