High‐Performance Zero‐Gap Glycerol‐Fed Electrolyzer for C3 Chemicals and Hydrogen Production

Advanced Materials, EarlyView.
This work presents a dynamic, self‐regulating operation strategy that enables selective glycerol electrooxidation in the OER‐free regime, co‐producing C3 chemicals and hydrogen at cell voltages below 1.25 V. Voltage‐ and temperature‐resolved analyses define optimal operating conditions, achieving a sustained current density of 500 mA cm−2 at ∼1.21 V ...

Flexible fiber batteries for applications in smart textiles

, 2013
Here we discuss two alternative approaches for building flexible batteries for applications in smart textiles. The first approach uses well-studied inorganic electrochemistry (Al-NaOCl galvanic cell) and innovative packaging in order to produce batteries

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

Advanced Materials, EarlyView.
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Maximize the Electrocatalytic Activity of Pt Toward Ethanol Oxidation via Engineering PdPt1 Single‐Atom Alloy Skin

Advanced Materials, EarlyView.
Maximizing atomic utilization of Pt is crucial for efficient electrocatalysis. We constructed a tensile‐strained PdPt1 single‐atom alloy (SAA) skin by implanting atomically dispersed Pt onto the surface of intermetallic Pd5Bi3 core‐ultrathin Pd shell octahedrons, fully exposing active Pt atoms to boost ethanol oxidation electrocatalysis.
