Integrating Automated Electrochemistry and High‐Throughput Characterization with Machine Learning to Explore Si─Ge─Sn Thin‐Film Lithium Battery Anodes

Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
A closed‐loop, data‐driven approach facilitates the exploration of high‐performance Si─Ge─Sn alloys as promising fast‐charging battery anodes. Autonomous electrochemical experimentation using a scanning droplet cell is combined with real‐time optimization to efficiently navigate composition space.

CFD modeling and sensitivity‐guided design of silicon filament CVD reactors

AIChE Journal, EarlyView.
Abstract Filament‐based chemical vapor deposition (CVD) for silicon (Si) coatings is often treated as an adaptation of planar deposition. But this overlooks fundamental shifts in transport phenomena and reaction kinetics. In filament CVD, the filament acts as a substrate, heat source, and flow disruptor simultaneously. In this work, we ask: What really

Hierarchically engineered electrocatalysts for durable oxygen reduction in zinc–air batteries

AIChE Journal, EarlyView.
Abstract Rechargeable zinc–air batteries (ZABs) are promising energy storage systems but are limited by sluggish oxygen reduction reaction (ORR) kinetics at the air cathode. Herein, we report hierarchically engineered cobalt tetraaminophthalocyanine/MXene (CoPc/MXene) electrocatalysts prepared via cetyltrimethylammonium bromide‐mediated self‐assembly ...

Solid particles focusing, orienting, and de‐focusing in planar Poiseuille flow

AIChE Journal, EarlyView.
Abstract Three‐dimensional, time‐dependent lattice‐Boltzmann simulations of neutrally buoyant particles in planar Poiseuille flow have been performed. The particles are spherical or cylindrical (the latter with a length over diameter ratios in the range 1/3 to 2) and have volume fraction ranging from virtually zero (one particle) to 0.15. The channel's

The Stresses in Rotating Disks

Journal of Fluids Engineering, 1931
Abstract This paper comprises the results of a photoelastic investigation, sponsored by The Norton Company, of the stresses in rotating disks. The classical theory of Chree with a few additions is presented, and the results of the experimental determinations are compared with the theory as well as actual breakages of vitrified wheels.

Magnetic rotating disk viscometer

International Journal of Thermophysics, 1989
A rotating disk viscometer has been developed aiming at measuring the viscosity at the critical consolute point of binary mixtures in the true hydrodynamic limit. The viscometer consists of a small magnetized disk set into slow rotation by a uniformly rotating magnetic field.

Rotating flows over a rotating disk

Ingenieur-Archiv, 1965
Abstract : Local boundary layer approximations of first order are computed for axisymmetric motions which rotate over a rotating disk in the same and opposite directions. The secondary motions, which are produced by the friction forces at the rotating disk, are essentially of pure stagnation type, distorted stagnation type, cell type, and pure wake ...

An Asymptotic Solution of a Rotating Disk

Journal of Applied Mechanics, 1971
The solution of the problem of a thin circular disk rotating at a constant angular velocity about its axis is obtained as a formal power series of the thickness-diameter ratio. The matching of the inner and outer expansions at a circular edge is carried out in detail for the stress conditions as well as for the displacement conditions.
