Feasibility of Nitrogen as a Carrier Gas for Inconel Cold Spray in Hydropower Application

Advanced Engineering Materials, EarlyView.
N2, despite being nearly two orders of magnitude cheaper than He, is a feasible carrier gas for cold spray Inconel coatings in hydropower repair applications when higher gas temperature and pressure are used. Reducing powder size significantly improved cavitation resistance, while the addition of fine chromium carbide particles further enhanced erosion

Multibubble cavitation inception

Physics of Fluids, 2009
The inception of cavitation in multibubble cases is studied numerically and theoretically to show that it is different from that in single-bubble cases in several aspects. Using a multibubble model based on the Rayleigh–Plesset equation with an acoustic interaction term, we confirmed that the recently reported suppression of cavitation inception due to

Halide Perovskite Integrated Photovoltaic Cathodes Incorporating Pt on ZIF‐8‐Derived Carbon for Solar Hydrogen Production

Advanced Functional Materials, EarlyView.
A low‐Pt catalyst supported on zeolitic imidazolate framework (ZIF‐8)‐derived porous carbon and graphite is integrated with a halide perovskite photovoltaic, yielding cathodes that achieve a high photocurrent density (∼20 mA cm−2) under simulated sunlight and exhibit remarkable stability in acidic media over several days, thereby demonstrating a ...

Utilization of Schnerr-Sauer Cavitation Model for Simulation of Cavitation Inception and Super Cavitation

, 2021
In this study, Reynolds-Stress-Navier-Stokes framework is utilized to investigate the flow inside diesel injector nozzle. The flow is assumed to be multiphase as formation of vapor by pressure drop is visualized. For pressure and velocity linkage, coupled algorithm is used.

Functional Disorder at the Neural Interface: How Disordered Nanostructures Promote Proper Growth and Differentiation in In Vitro Neural Cultures

Advanced Science, EarlyView.
This work provides a practical guide for neuroengineers to design advanced neural interfaces, embracing and tailoring the concept of functional disorder. By bridging 2D and 3D in vitro models, this work highlights how non‐periodic, spatially heterogeneous, multiscale nanotopography can enable more physiologically relevant platforms for studying neural ...

Tailored D‐π Conjugation Boosts Piezocatalytic CO2 Reduction in a Platinum(II)‐Acetylide Framework

Advanced Science, EarlyView.
The highly conjugated metalII‐acetylide framework demonstrates efficient ultrasound‐driven conversion of CO2 to CO. The piezoelectric field generated by ultrasound facilitates electron transfer from the tetraphenylene π‐column to the MII‐bis(acetylide) moiety, enabling CO2 activation. Compared to PdII‐ and NiII‐based analogues, the stronger d–π orbital
