Core Loss of MgZn Ferrite.

open access: yesJournal of the Japan Society of Powder and Powder Metallurgy, 1999
The effects of substitution of Mn2O3 for Fe2O3 Or CuO for MgO in MgZn ferrite have been studied in order to achieve low core loss, focusing on the microstructure, the initial permeability and the resistivity of MnZn, MnMgZn, and MnMgCuZn ferrites.Initial permeability and resistivity of both MnMgZn and MnMgCuZn ferrites are higher than those of MgZn ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

A Novel Excitation Approach for Power Transformer Simulation Based on Finite Element Analysis

open access: yesApplied Sciences, 2021
Power transformers play an indispensable component in AC transmission systems. If the operating condition of a power transformer can be accurately predicted before the equipment is operated, it will help transformer manufacturers to design optimized ...

Physical Modeling of Core Losses in Ferrite E-Cores

open access: yesIEEE Open Journal of Power Electronics
The development of advanced power electronic converters requires an accurate calculation of core losses in magnetic devices. But the losses in the widely used ferrite cores depend on the shape of the core, especially above 100kHz, meaning that core losses can not be estimated by simply scaling reference data with respect to the volume of the core.

Fabrication of multiple parallel suspended-core optical fibers by sheet-stacking [PDF]

open access: yes, 2014
We demonstrate the fabrication of a novel type of optical fibers with multiple parallel air-suspended cores by the sheet-stacking method. Using this technique we have constructed optical fibers with up to 10 parallel micron-size suspended cores. No extra

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Low-Loss Fe@BN Magnetic Powder Cores Enabled by Thiol-Functionalised Boron Nitride Interfacial Coating

open access: yesMagnetochemistry
Iron powder cores are widely used in cost-sensitive low- to medium-frequency applications because of their high saturation magnetisation, low cost and favourable formability.
