Fabrication of Ultra‐Thick Masks for X‐Ray Phase Contrast Imaging at Higher Energy
Advanced Materials Interfaces, EarlyView.This work shows a fabrication route to 500 µm thick X‐ray masks the thickest ever reported in the literature combining dynamic optimization of etching parameters and superconformal bismuth‐mediated gold filling. Their use in an Edge Illunomination set‐up showed their higher phase sensitivity at higher energies compared to thinner masks, especially for ...

On the Mechanism of Large Amplitude Flapping of Inverted Foil in a Uniform Flow [PDF]
, 2017 An elastic foil interacting with a uniform flow with its trailing edge clamped, also known as the inverted foil, exhibits a wide range of complex self-induced flapping regimes such as large amplitude flapping (LAF), deformed and flipped flapping. Here, we perform three-dimensional numerical experiments to examine the role of vortex shedding and the ...

Experimental method for perching flapping-wing aerial robots [PDF]
arXiv, 2023 In this work, we present an experimental setup and guide to enable the perching of large flapping-wing robots. The combination of forward flight, limited payload, and flight oscillations imposes challenging conditions for localized perching. The described method details the different operations that are concurrently performed within the 4 second ...

Progress and Application of Multifunctional Hydrogel in Radioactive Skin Injury
Advanced Materials Interfaces, EarlyView.This review examines healing challenges in radiation‐wound injuries, where ionizing radiation impairs immune and tissue repair processes. Hydrogels, with their biocompatibility, antimicrobial properties, and drug delivery capabilities, present a transformative solution. It compares hydrogel efficacy in radiation‐induced versus common wounds, highlights

Pneumatic Pressure Control Using on‐off Valves with Pulse Width Modulation
Chemical Engineering &Technology, Volume 46, Issue 1, Page 21-28, January 2023., 2023 To reduce hysteresis and improve accuracy of a two‐stage airplane flow valve, an on‐off switching valve with its pulse width modulation (PWM) control is proposed as a first stage in replacement of a currently used servomotor‐controlled valve. A method is introduced for properly choosing the on‐off valve and tuning the PWM parameters.
