Advanced Materials, EarlyView.2D α‐Co(OH)2 interleaved with Mo species displays an appealing dual functionality for the production and use of green hydrogen.Mo incorporation greatly benefits the electrochemical behaviour in Oxygen Evolution Reaction for H2 production, while the magnetocaloric response at liquid H2 temperature paves the way for alternative cryogenic refrigerants ...

Note on porous rotating disk flow
, 2000 We revisit the classical Karman rotating disk problem. A series analysis is used to derive estimates of boundary conditions at the surface. Using these estimates, computed thermal and flow fields for large mass transfer through the disk are readily ...

Advanced Materials, EarlyView.Phase boundaries between Co2P and CoP are constructed through a controlled transformation of Co to Co2P‐CoP branched nanoparticles. The polycrystalline mixed‐phase Co2P‐CoP branches are enriched with phase boundaries that stabilize Co active sites for OER. This work highlights phase boundary engineering as a powerful approach to tailor active sites and

Extension of the Rotating Disk Electrode Method to Thin Samples of Non-Disk Shape
, 2019 A straightforward approach is presented to make thin electrode samples of non-disk shape compatible with the rotating disk electrode method, by merely attaching the sample on the rotating shroud and confining the area exposed to the electrolyte using ...

Basic Generic Properties of Regular Rotating Black Holes and Solitons
Advances in Mathematical Physics, 2017 We present a systematic description of the basic generic properties of regular rotating black holes and solitons (compact nonsingular nondissipative objects without horizons related by self-interaction and replacing naked singularities). Rotating objects

Novel design of rotating disk for improving separation efficiency of microfiltration by CFD
, 2014 碩士本研究使用計算流體力學(CFD)的方法來討論迴轉盤結構對速度和剪應力分佈的影響，其中結構的改變包含了迴轉盤葉片的種類與數目。研究選用的模組為內置迴轉盤的單一圓柱形濾室，並且將濾膜固定在靠近濾室底部的多孔性支撐材。本研究利用Fluent計算流體力學軟體來模擬三個維度之模組內部流場，其數值方法為網格有限體積法與紊流中的RNG k-epsilon模式進行連續及動量守恆方程式求解，並且選用不同迴轉盤結構與改變操作條件進行分析探討。迴轉盤的操作轉速設定至3000 rpm並且選用進料流速範圍從1.18 m ...
