2D Co‐Assembly of Solid Acids Enables Stable Superprotonic Conduction Above 260°C

Advanced Functional Materials, EarlyView.
A two‐dimensional co‐assembly strategy integrates antimony phosphate and phosphotungstic acid nanosheets into free‐standing inorganic lamellar membranes with confined acid–acid interfaces. The resulting interfacial hydrogen‐bond network enables anhydrous proton conductivity exceeding 0.1 S cm−1 at 260°C and supports stable high‐temperature fuel‐cell ...

The efficiency of secondary electron emission

Proceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1933
Abstract The velocity distribution of the secondary electrons produced by bombarding a metallic face with a stream of primary electrons has been a matter of interest ever since the beginning of the study of secondary electron emission.

Chitin‐Derived Carbon‐Metal Functional Materials

Advanced Functional Materials, EarlyView.
Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.

Roll‐to‐Roll Processable EC/TC Hybrid Smart Windows Driven by a Bidirectional Dual‐Chromic Polymer Electrolyte

Advanced Functional Materials, EarlyView.
We present a scalable EC/TC hybrid smart window using a DCPE that enables tunable solar modulation (ΔTsol:15–43%), fast electrochromic switching (<90 s), and strong thermal blocking (10–14°C reduction). HPMC improves thermal stability, while an optimized ISL enhances EC performance.

Mechanical Programming of PEGDA‐β‐CD Polyrotaxane‐Based Hydrogels via Host–Guest Molecular Recognition

Advanced Functional Materials, EarlyView.
A mechanically programmable hydrogel for tissue engineering is developed by modulating the molecular threading density of poly(ethylene glycol) diacrylate‐β‐cyclodextrin (PEGDA‐β‐CD) polyrotaxane and combining it with β‐CD‐modified gelatin. The polyrotaxane‐guided transition from disordered pores to laminar microstructures enables precise tuning ...

Simulation of secondary electron emission in an electron gun

Physics Procedia, 2008
To decrease the size of electron beam in an electron gun, sometimes an aperture with a small hole is used to cut off the electrons with large divergence angle. However, a few secondary electrons may be emitted when the primary electrons bombard on this aperture. This article simulates the secondary electron emission in an electron gun.

Bio‐Inspired Artificial Ionic Mechanoreceptor

Advanced Functional Materials, EarlyView.
A skin‐inspired artificial mechanoreceptor based on ionic interactions is presented for biomimetic tactile sensing. Pressure‐driven ionic redistribution within microfluidic channels generates a self‐powered electrical signal without external bias. The generated waveform exhibits mechanoreceptor‐like temporal features, including overshoot and undershoot,

Heat Flow of a Two-Electron-Temperature Plasma through the Sheath in the Presence of Electron Emission

, 1992
"The electrostatic sheath and the heat flow of a two-electron-temperature plasma in the presence of electron emission is investigated analytically. It is shown that the energy flux is remarkably enhanced up to a value near the electron free-flow energy ...

Ultrahigh secondary electron emission of carbon nanotubes

, 2010
The secondary electron emission of the tube bodies of single-walled carbon nanotubes is found to be ultrahigh and comparable with that of diamond, when the nanotubes are connected with electron reservoir.
