Adjustable High Current Low Profile Sandwich Inductor Using Nanocrystalline Flake Ribbon Core

IEEE Open Journal of Power Electronics
Compact and high current inductors determine the power density and efficiency of voltage regulators (VRs) for computing ICs. Conventional moulding structures using powder cores and gapped ferrite cores are reaching the limits of size miniaturization.

A Multi‐Scale Machine Learning Framework for the Inverse Design of High Entropy Alloys

Advanced Engineering Materials, EarlyView.
High‐entropy alloys offer vast potential for various applications, including electrocatalysis; however, their compositional complexity challenges conventional screening. We introduce an inverse‐design framework combining two neural networks to determine optimal compositions and reconstruct nanoparticle geometry from targeted properties and conventional

An Investigation of the Magnetic Properties of Iron-based Soft Magnetic Composites Coated by Sodium Silicate Insulator

Journal of Advanced Materials in Engineering, 2018
In this study, iron powder (~45 μm) with the  minimum purity of 99% was insulated by the 1 to 4 wt% sodium silicate insulator (SiO2.3Na2O solution in 40 wt% water) and the 0.5 wt% zinc stearate.

Fusogenic RNA Nanomodules for Fusion‐Mediated and Multiplexed siRNA Delivery

Advanced Functional Materials, EarlyView.
A fusogenic lipid‐layered RNA nanomodules (L‐CRAMs) enable high‐capacity and long‐lasting siRNA delivery through membrane fusion. These nanomodules carry exceptionally large siRNA payloads, avoid conventional endosomal uptake, and release multiple functional siRNAs through Dicer‐mediated processing.

Synergistic Electrical–Magnetic–Thermal Response of Fe Soft Magnetic Composites Enabled by Thiol-Functionalised Silicon Nitride Nanosheet Interfacial Engineering

Magnetochemistry
Pure Fe soft magnetic composites (SMCs) hold a prominent position in cost-sensitive 10–100 kHz medium-to-low-frequency power devices owing to their low raw-material expenditure and high saturation magnetisation.

Analytical Models for HF-Losses of Litz Wire in Inductors With Arbitrary Winding and Gap Arrangements

IEEE Open Journal of Power Electronics
Dueto 2D fields in the core window of inductors (e.g. the fringing field caused by core gaps) large errors can occur in the winding loss calculation, when the assumptions, that the $H$-field is parallel to the winding layers and constant along the field ...

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

Advanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...
