Effects of Regional Magnetic Field on Rotating MHD Flow Field of Unity Magnetic Prandtl Number

open access: yesJournal of Applied Mathematics, 2012
This work numerically studies the flow pattern of a magnetic fluid filled within an annulus whose inner cylinder is moving at a constant rotational speed, while the outer cylinder is stationary but under the influence of a nonuniform external magnetic ...

Decoding Synergistic Pathways in Bimetallic MOFs for Advanced Oxidation Processes

open access: yesAdvanced Materials, EarlyView.
This review presents a unified framework linking metal pairing and framework design with electronic structure, redox cycling, oxidant activation, reactive‐species generation, and catalytic performance across photocatalytic and oxidant‐based BMOF‐AOPs. The resulting design principles guide the development of hydrolytically stable and efficient BMOFs for

Tenzel Semicircular Flap

open access: yes, 2016
The Tenzel semicircular flap was first described by Dr. Richard Tenzel in 1975. The semicircular flap is useful for reconstruction of central lower eyelid defects. The Reverse Tenzel semicircular flap is performed for central upper eyelid defects.

Lattice Strain and Built‐In Field Synergistically Boost Urea Oxidation via Dynamic NiOOH Mediation at Multiphase Heterointerfaces

open access: yesAdvanced Materials, EarlyView.
A sulfur‐doped lignin‐derived carbon‐coated Ni‐NiO‐MoO2 nanorod array was synthesized, exhibiting enhanced UOR performance ‐ due to lattice‐strain and built‐in electric field effects by multiphase heterogeneous interface in Ni‐NiO‐MoO2@SC, excellent corrosion resistance, mass‐transport ability, and long‐term stability (500 mA cm−2 at 1.53 V for 500 h ...

Simulation of Bending Fracture Process of Asphalt Mixture Semicircular Specimen with Extended Finite Element Method

open access: yesAdvances in Materials Science and Engineering, 2018
In order to numerically simulate the whole fracture process including the initiation and propagation of crack in asphalt concrete semicircular specimens under external force, the extended finite element method (XFEM) was adopted considering the shortcomings of the conventional finite element method (FEM).
