Field-Balanced Windings for High-Frequency Transformers

IEEE Open Journal of Power Electronics
High-frequency operation is a well-established strategy for miniaturizing power converters, but eddy-current losses in magnetics thermally limit its effectiveness in high-power converters. Interleaved windings, which reduce the magnetic fields around the

A narrow bandgap Schottky heterojunction Fe2N/CeO2 microneedle triggering sonodynamic reactive oxygen species storm for drug‐resistance‐free skin fungal infection

BMEMat, EarlyView.
Inorganic sonosensitizers suffer from inefficient electron‐hole separation, rapid recombination, and wide bandgaps in anti‐fungal applications. We propose MN@Fe2N/CeO2 to directly eliminate fungi without drug resistance. Combining semiconductor CeO2's advantages with Fe2N's high work function and activity enables efficient Schottky heterojunctions ...

An electrical PD location method applied to a continuous disc type transformer winding [PDF]

, 2003
A 6.6 kV continuous disc type winding of a distribution transformer is used to investigate the propagation of partial discharges (PD) with the aim of location. The winding was modelled, as multiconductor transmission lines with each turn represented by a

Bit-Interleaved Sphere-Packing-Aided Iteratively Detected Space-Time Coded Modulation

, 2009
We design a bit-interleaved space-time coded modulation scheme using iterative decoding (BI-STCM-ID) combined with a new multidimensional mapping scheme invoking sphere-packing (SP) modulation, which we refer to as the space-time block-coded sphere ...

Single‐Cell Reporter Dynamics During the First Two Rounds of Rhinovirus Plaque Growth

Cytometry Part A, EarlyView.
ABSTRACT When infection spreads from an initially infected cell through a cell monolayer, the resulting plaque records successive rounds of virus–cell interaction. Fluorescent reporter viruses permit this process to be followed at single‐cell resolution, but whether secondary infected cells retain detectable signatures associated with their plaque of ...

One‐Step Synthesis of Si–Graphene Heterostructures via in‐Flight Gas‐Phase Mixing for High‐Capacity Silicon‐Rich Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A one‐step gas‐phase synthesis directly assembles amorphous Si nanoparticles with few‐layer graphene heterostructures via in‐flight mixing. Compositions with only 15 wt.% FLG deliver ~2800 mAh g−1 (Si + FLG) at 0.05 C and retain ~1400 mAh g−1 after 100 cycles at a high cycling rate of 1 C, enabled by a percolated, strain‐buffering graphene network that
