Physics Bulletin, 1963 By J. R. Acton and J. D. Swift London: Hey wood and Co. Ltd. 1963. Pp. vii + 351. Price 67s. 6d. The arrangement of this book is unusual but very good, but perhaps the title is misleadingly unprepossessing. The development is very logical and careful and starts from basic collision processes to go through swarm constants, etc., to a description of ...

3D Printing of Stretchable, Compressible and Conductive Porous Polyurethane for Soft Robotics
Advanced Materials Technologies, EarlyView.A 3D‐printable porous dopamine‐polyurethane acrylate elastomer results in conductive, stretchable, and compressible structures that can be metallized in situ through catechol‐mediated silver reduction. The resulting material function as both compliant soft robot with a and strain sensors without complex assemblies, enabling fully 3D‐printed soft ...

A Review Paper on “Graphene Field Emission for Electron Microscopy”
Applied Sciences, 2018 Although good field emission from graphene has been demonstrated from a wide variety of different microfabricated structures, very few of them can be used to improve the design of cold field emitters for electron microscopy applications.

Advanced Robotics Research, EarlyView.A flexible liquid‐crystalline electrolyte membrane via in situ photopolymerization of a phosphate‐functionalized mesogen, ionic liquid, and diacrylate monomer is developed. The resulting smectic B (SmB)‐phase structure enables 2D ion transport with high conductivity (10−4 S cm−1).

Advanced Science, EarlyView.A transfer‐free fabrication method enables multilayer graphene microelectrodes as small as 10 µm, eliminating reliability issues of manual graphene transfer. These electrodes record neural activity in brain slices with exceptional signal‐to‐noise ratios (up to 25–40 dB) while maintaining optical transparency for multimodal applications.

Nanoscopic Imaging the Lithiation of Sulfur Nanoparticles under Electron Beam Irradiation
Advanced Science, EarlyView.ABSTRACT In situ Transmission Electron Microscopy (TEM) provides powerful insights into the reaction mechanisms of Lithium‐Sulfur (Li‐S) batteries. However, distinguishing intrinsic electrochemical behaviors from artifacts induced by high‐energy electron beam irradiation remains a critical challenge.
