All‐Polyimide‐Mediated Liquid Metal Assembly on Aerogels for Breathable and Robust Electronic Skins

Advanced Materials, EarlyView.
An all‐polyimide‐mediated assembly strategy resolves the fundamental conflict between physiological breathability and electromechanical robustness in wearable electronics. By integrating a polyamic acid‐encapsulated liquid metal ink onto an ultralight polyimide aerogel, imidization‐induced contraction enables low‐temperature conductive activation and ...

pH Coupled Co-Precipitation of Alkaline-Earth Carbonates and Silica - Complex Materials from Simple Chemistry

, 2017
The present work deals with the mineralization of alkaline-earth carbonates (mainly barium carbonate) from dilute silica solutions at high pH. It has for long been known that the concerted interaction between these purely inorganic components leads to ...

Conductive Additives for Next‐Generation Batteries: Emphasizing the Potential of Bio‐Derived 3D Carbon Architectures at Electrode–Electrolyte Interfaces

Advanced Materials Interfaces, EarlyView.
3D conductive frameworks can maintain continuous electron transport, mechanical stability, and interfacial integrity, helping next‐generation batteries operate more efficiently. This Review examines their relevance to Si anodes, all‐solid‐state batteries, and dry‐processed electrodes, and highlights bio‐derived carbons as sustainable, structurally ...

Minimizing heterogeneity of sugarcane bagasse ash by silica extraction via sol gel process

Next Materials
This work proposes to extract silica via the sol-gel process using molecular precursors from four distinct sugarcane bagasse ashes. The process comprised cleaning, silica extraction using sodium silicate, and gel formation by lowering the solution pH ...

Tensile properties of in-situ precipitated polydimethylsiloxane networks

eXPRESS Polymer Letters, 2013
Tensile propertiesof polydimethylsiloxane (PDMS) networks filled with in-situ precipitated silica were investigated. Experimental results showed that increasing the swelling time of cured rubber sheets in tetraethoxysilane (TEOS) solution or elevating ...

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...
