Influence of Tongue Clearance Flow on Aerodynamic Noise Source of a Forward Curved Fan [PDF]
, 2011 A visualization method of aerodynamic noise source based on momentum in wake of a centrifugal impeller is proposed. The characteristics of the fan noise operated at the design point and the off design point are discussed by the visualization.

Advanced Materials Interfaces, EarlyView.Simplified quantum sensing technique for the detection of short electrical signals occurring in neuronal signaling or bioinspired technologies. We demonstrate a single frequency continuous‐wave optically detected magnetic resonance (CW‐ODMR) approach to sense signals that can be as short as 0.2 ms.

Atomic Layer Deposition of Metallic Molybdenum Dioxide Thin Films Enabling High‐k Rutile Capacitors
Advanced Materials Interfaces, EarlyView.The first direct atomic layer deposition (ALD) process of molybdenum dioxide (MoO2) thin films is reported using molybdenum(II) acetate dimer (Mo2(OAc)4) and oxygen (O2) as precursors at 235°C–275°C. The films are crystalline, exceptionally pure, and conductive.

A Survey of Interlayer Interaction Models for Graphene and Other 2D Materials
Advanced Materials Interfaces, EarlyView.Van der Waals interactions arising from electronic polarization at atomically close interfaces generate corrugated interlayer energy landscapes that govern normal and tangential tractions. This review presents an overview of quantum, atomistic, analytical, and continuum modeling approaches, highlighting their roles across length scales in capturing ...
