Size Effect on Failure of Pre-stretched Free-Standing Nanomembranes [PDF]
, 2010 Free-standing nanomembranes are two-dimensional materials with nanometer thickness but can have macroscopic lateral dimensions. We develop a fracture model to evaluate a pre-stretched free standing circular ultrathin nanomembrane and establish a relation

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

Valveless pressure regulation with a submerged micro‐hole [PDF]
Journal of the Chinese Institute of Engineers, 2002 Abstract This study aims at controlling air pressure fluctuation in a chamber from which liquid is being drained continuously by using a submerged micro‐hole. In practical applications, this test chamber is used to simulate the commercial ink cartridge of a thermal bubble inkjet printhead.

Advanced Functional Materials, EarlyView.In‐situ doping during growth of SnSe and subsequent attachment of SnS produces high‐quality lateral pn‐heterojunctions between van der Waals semiconductors. Electron beam induced current measurements demonstrate electrically active pn‐junctions, paving the way for devices that harness charge separation at lateral interfaces in layered heterostructures.

Numerical Analysis of Film Cooling from Micro-Hole [PDF]
, 2021 The performance of aircraft gas turbine engines mainly depends on performance of the turbine which expands the combusted air into the atmosphere. The turbine is a critical part which gets affected by the hot gas from combustor exhaust. So in order to enhance the performance of gas turbine engines, a proposed cooling type called film cooling is used for

Material processing with pulsed radially and azimuthally polarized laser radiation [PDF]
, 2018 We report on the generation of radially and azimuthally polarized Q-switched laser radiation and its application in material processing. The power levels were sufficiently high to study micro-hole drilling in different metals.

Micro Hole Piercing for Ultra Fine Grained Steel
Materials Science Forum, 2012 Ultra fine grained steels have been developed by many researchers. However, the study of influence on processes and product functions from different grain size are limited because the size of bulk material was small for these products. Authors have developed the production process of thin ultra fine grained stainless steel coil, and the effects are ...
