A Bifunctional Fibrous Scaffold Implanted with Amorphous Co2P as both Cathodic and Anodic Stabilizer for High‐Performance Li─S Batteries

Advanced Science, EarlyView.
An amorphous Co2P‐embedded porous carbon nanofiber membrane (A─Co2P/PCNF) via electrospinning/in situ phosphorization is developed to serve as the dual‐electrode stabilizer for Li─S batteries. The amorphization strategy enables more exposed undercoordinated Co sites with optimized d‐band centers, enhanced LiPSs adsorption/catalysis, and lithiophilicity‐

Health‐related quality of life following total minimally invasive, hybrid minimally invasive or open oesophagectomy: a population‐based cohort study

BJS (British Journal of Surgery), EarlyView., 2020
All patients operated for oesophageal cancer in Sweden from 2013 to April 2018 were identified, and 246 patients were recruited to this population‐based nationwide Swedish study. The results show that longitudinal health‐related quality of life after minimally invasive oesophagectomy was similar to that of the open surgical approach.

Recombinant spider silk from aqueous solutions via a bio-inspired microfluidic chip

Scientific Reports, 2016
Spiders achieve superior silk fibres by controlling the molecular assembly of silk proteins and the hierarchical structure of fibres. However, current wet-spinning process for recombinant spidroins oversimplifies the natural spinning process. Here, water-

SPIDER: Probing the Early Universe with a Suborbital Polarimeter

, 2013
We evaluate the ability of SPIDER, a balloon-borne polarimeter, to detect a divergence-free polarization pattern ("B-modes") in the Cosmic Microwave Background (CMB).

Elastic Fiber Programming for Simplified Pneumatic Control in Soft Robots

Advanced Science, EarlyView.
This study introduces a novel approach to designing pneumatic soft actuators by leveraging elastic fiber programming to achieve tailored constitutive equations. Using pre‐stretched elastic fibers with varying properties and modurization, the soft robots can demonstrate diverse motions from a single pressure source. This simplifies control systems while

Protected Chaos in a Topological Lattice

Advanced Science, EarlyView.
Topological and chaotic dynamics are often considered incompatible, with one expected to dominate or disrupt the other. This work reveals that topological localization can persist even under strong chaotic dynamics and, counter‐intuitively, protect chaotic behavior.

SPIDER: Near-Optimal Non-Convex Optimization via Stochastic Path Integrated Differential Estimator [PDF]

arXiv, 2018
In this paper, we propose a new technique named \textit{Stochastic Path-Integrated Differential EstimatoR} (SPIDER), which can be used to track many deterministic quantities of interest with significantly reduced computational cost. We apply SPIDER to two tasks, namely the stochastic first-order and zeroth-order methods.

Biomimetic Adhesion/Detachment Using Layered Polymers with Light‐Induced Rapid Shape Changes

Angewandte Chemie, EarlyView.
Geckos achieve rapid adhesion and detachment through their hierarchically structured toe pads. Inspired by this, we developed a crosslinked polymer film with a nanoscale layered structure that undergoes high‐speed, reversible expansion, and contraction under UV light.

Highly Active IrRuOx/MnOx Electrocatalysts with Ultralow Anode PGM Demand in Proton Exchange Membrane Electrolyzers

Advanced Energy Materials, EarlyView.
MnOx‐supported IrRuOx exhibits outstanding OER performance in both liquid electrolytes and real cell environments. The MnOx not only enhances the dispersion of IrRuOx but also induces a compressive strain effect. The incorporation of Ru leads to surface reconstruction.
