Effect of graphene oxide on the corrosion resistance and electromagnetic propertiese of FeSiAl alloy powders

Fenmo yejin jishu, 2021
To improve the corrosion resistance of the FeSiAl (FSA) alloys in the salt spray environment, the para-aminobenzoic acid (PABA) and graphene oxide (GO) were sequentially grafted and coated on the surface of the FeSiAl alloy powders to form the FSA/PABA ...

Effect of terahertz irradiation on DNA damage repair in living cells

FEBS Open Bio, EarlyView.
We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Electromagnetic and radar absorption characteristics of iron/epoxy polymer composites based on dispersion and mixing ratios of iron particles with different particle sizes

Materials Research Express
This study proposes a single-layer radar absorber using iron (Fe) powder and epoxy. Two types of Fe particles with different particle sizes were utilized as fillers to impart electromagnetic(EM) properties to the epoxy.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

A resistance heating assisted free space method to measure temperature-dependent electromagnetic properties of carbon fiber reinforced polymer composites

Polymer Testing, 2023
Temperature-dependent electromagnetic properties are not only closely related to the manufacturing process of carbon fiber reinforced polymer (CFRP) components, e.g., curing of CFRP composites using microwaves, but also directly determines some key ...

Impact of Tissue Electromagnetic Properties on Radiation Performance of In-Body Antennas

IEEE Antennas and Wireless Propagation Letters, 2018
In-body antennas couple strongly to surrounding biological tissues, thus, resulting in radiation efficiencies well below 1%. Here, we quantify how the permittivity and conductivity, each individually, affect the radiation efficiency of miniature ...

A Practical Noise2Noise Denoising Pipeline for High‐Throughput Raman Spectroscopy

Advanced Engineering Materials, EarlyView.
A lightweight and reproducible denoising pipeline for high‐throughput Raman spectroscopy is introduced, based on a 1D convolutional autoencoder trained with a Noise2Noise strategy. Using only repeated short‐exposure acquisitions, the method suppresses stochastic noise without reference spectra, enabling reliable spectral reconstruction while preserving
