Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

open access: yesAdvanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Droplet Triboelectrification on Liquid‐Like Polymer Brushes

open access: yesAdvanced Functional Materials, EarlyView.
This work investigates the triboelectrification of water droplets on polymer brush‐coated surfaces exhibiting minimal contact line pinning. Such surfaces enable the systematic study of electrode patterning and controlled changes in droplet contact area.

Thermal hysteresis in wettability and the Leidenfrost phenomenon

open access: yesPhysical Review Research
The Leidenfrost temperature (T_{L}), at which the liquid drop lifetime peaks on a superheated surface, is believed to be wettability dependent. Here, we show that the wettability effect on T_{L} is subject to the history of the surface temperature ...

Generation of Motion of Drops with Interfacial Contact

open access: yes, 2015
A liquid drop moves on a solid surface if it is subjected to a gradient of wettability or temperature. However, the pinning defects on the surface manifested in terms of a wetting hysteresis, or first-order nonlinear friction, limit the motion in the ...

Contact angle hysteresis of Newtonian fluid

open access: yesIOP Conference Series: Earth and Environmental Science, 2020
Abstract Contact angle hysteresis of Newtonian fluid is a fundamental and complicated phenomenon related to wetting and dewetting. This article reviews typical research progress of contact angle hysteresis and proposes some critical directions deserved to be investigated.

Selective Charge Injection via Topological van der Waals Contacts for Barrier‐Free p‐Type TMD Transistors

open access: yesAdvanced Functional Materials, EarlyView.
 Topological van der Waals contacts represent a new class of electrodes for 2D semiconductors, enabling precise control of the Schottky barrier height (SBH) and contact resistance (RC) through interlayer distance and orbital hybridization engineering. In Se‐based transition metal dichalcogenides, these contacts achieve an ultralow SBH of 7 meV, RC of 0.

Ultrahydrophobic Textiles Using Nanoparticles: Lotus Approach [PDF]

open access: yesJournal of Engineered Fibers and Fabrics, 2008
It is well established that the water wettability of ma-terials is governed by both the chemical composition and the geometrical microstructure of the surface.1 Traditional textile wet processing treatments do in-deed rely fundamentally upon complete ...
