Exploring Curvature Effects in Direct‐Written 3D Curved Hollow Magnetic Nanoshells

Advanced Functional Materials, EarlyView.
Fabricated by a hybrid FEBID/CVD method, 3D PtC/Co3Fe core–shell heterostructures with engineered curvature and shell thickness exhibit complex reversal modes with axially symmetric N'eel‐type domain walls. XMCD‐PEEM combined with full‐scale micromagnetic simulations reveal how curvature and thickness govern the domain wall energy landscape and shape ...

CCM and DCM analysis of quasi-z-source inverter [PDF]

2017 IEEE Conference on Energy Conversion (CENCON), 2017
This paper presents an analysis of a quasi-Z-source inverter (qZSI) operating in continuous conduction mode (CCM) and discontinuous conduction mode (DCM). The boundary between CCM and DCM is discovered and technique to avoid qZSI being operated in DCM is also discovered.

Chirality and Organization of Adsorbates Modify Surface Phonon Dynamics

Advanced Functional Materials, EarlyView.
Chirality and molecular organization are shown to influence surface phonon dynamics in gold films. Time‐resolved Joule heating measurements reveal that ordered homochiral monolayers increase the Debye temperature and disordered layers reduce it, while ordered racemic controls have no effect.
