Nonlinear phenomena in vibration control devices using Hula-Hoop and displacement magnification mechanism [PDF]
, 2020 The authors have been studying vibration control devices using Hula-Hoops. A displacement magnification mechanism has been devised so that vibration can be controlled even when the vibration amplitude of the main system to be controlled is small, and its

Why Is the Mechanism Underlying the Chiral‐Induced Selectivity Effect Still Challenging?
Advanced Materials, EarlyView.The chiral‐induced spin selectivity (CISS) effect is observed in many experimental configurations and for different materials. However, there are theoretical challenges in attempting to explain those results. A qualitative framework for explaining all the results is presented.

A Universal van der Waals Tunneling Injector for Monolayer CMOS
Advanced Materials, EarlyView.A universal van der Waals injector unlocks polarity‐flexible tunneling contacts for monolayer CMOS. SnSe2, an intrinsically degenerate 2D semiconductor, establishes polarity‐specific band alignments with both WSe2 and MoS2 channels, enabling steep switching, high on/off ratios, and a unified route to low‐power 2D logic.
