Transparent Photothermal Slippery Surface Based on Monolayer Self‐Assembled MXene Film for Anti‐Fogging and De‐Icing

Advanced Science, EarlyView.
The ultrathin (2.5 nm) MXene film self‐assembled at liquid interfaces breaks the trade‐off between transparency (82.5 %) and photothermal conversion effect (DT∼25.1°C ± 2.9 °C) under 100 mW cm−2. After encapsulated by a slippery surface with low adhesion, this transparent film can be applied in smart windows, eyewear, and optical sensors to autonomous ...

Microwave-induced excess quasiparticles in superconducting resonators measured through correlated conductivity fluctuations

, 2012
We have measured the number of quasiparticles and their lifetime in aluminium superconducting microwave resonators. The number of excess quasiparticles below 160 mK decreases from 72 to 17 $\mu$m$^{-3}$ with a 6 dB decrease of the microwave power.

Microwave-assisted High-Throughput Synthesis of Crystalline Porphyrin-based Two-dimensional Polymers for Neuromorphic Vision Sensor

, 2022
Abstract Emulating the biological visual adaptation in machine vision systems typically requires a neuromorphic vision sensor system that exhibits biomimetic light intensity-dependent photoadaptation. Inspired by the biological counterpart, porphyrin-based two-dimensional polymers (p2DPs) are of high interest for adaptative sensor due to their ...

Advances and Perspectives in Graphene‐Based Quantum Dots Enabled Neuromorphic Devices

Advanced Science, EarlyView.
Graphene‐based QDs are zero‐dimensional carbon nanomaterials with pronounced quantum confinement and tunable electronic structures. Herein, we summarize their synthesis strategies and functionalization methods, and highlight their functional roles and operating mechanisms in devices, as well as recent advances in neuromorphic electronics. We anticipate
