Spheroid‐On‐A‐Drop: A Modular Droplet Microfluidics Platform

Advanced Materials Technologies, Volume 11, Issue 18, 18 September 2026.
The proposed Spheroid‐on‐a‐Drop platform represents a reproducible and tunable platform for the fabrication of biocompatible GelMA‐based microgels, able to support controlled 3D tumor spheroid culture. Its precise control over droplet dynamics and cell distribution paves the way for advanced applications in tissue modeling, drug screening, and ...

Synthesis of FeNi Alloy Nanomaterials by Proteic Sol‐Gel Method: Crystallographic, Morphological, and Magnetic Properties

Journal of Nanomaterials, Volume 2016, Issue 1, 2016., 2016
Proteic Sol‐Gel method was used for the synthesis of FeNi alloy at different temperature conditions and flow reduction. The solids were characterized by XRD, H2‐TPR, SEM, TEM, Mössbauer spectroscopy, and VSM. It was observed by X‐ray diffraction pure FeNi alloy in the samples reduced at 600°C (40 mL/min H2 flow) and 700°C (25 mL/min H2 flow).

Energy Band Alignment and Electro‐Optical Behavior of Nearly Unstrained Monolayer MoS2 Heterostructures With GaN

Advanced Materials Interfaces, Volume 13, Issue 16, 18 August 2026.
Large size (∼100 µm) monolayer MoS2 grown by LPI‐CVD on n‐GaN exhibit a high n‐type doping, very low strain, and a type‐I band alignment at MoS2/GaN interface. Photocurrent measurements under illumination with photon energies from ∼2 to ∼5 eV show superior electro‐optical performances of these MoS2/n‐GaN heterojunctions as compared to Ni/n‐GaN devices ...

Metallic Magnetic Nanoparticles

The Scientific World Journal, Volume 5, Issue 1, Page 972-1001, 2005., 2005
In this paper, we reviewed some relevant aspects of the magnetic properties of metallic nanoparticles with small size (below 4 nm), covering the size effects in nanoparticles of magnetic materials, as well as the appearance of magnetism at the nanoscale in materials that are nonferromagnetic in bulk.

Robust Directional Analysis of Magnetic Microscopy Images Using Non‐Linear Inversion and Iterative Euler Deconvolution

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract In paleomagnetism, bulk measurements of entire samples have traditionally been used to characterize remanent magnetization. While effective, this approach provides only a general directional estimate and cannot resolve spatial variability or magnetization at the grain scale.

Influence of Nanocrystalline Structure on the Magnetic Properties of Wires and Microwires

Texture, Stress, and Microstructure, Volume 32, Issue 1-4, Page 245-267, 1999., 1997
The determining factors of the outstanding magnetic properties of the so‐called nanocrystalline materials are described. The discussion is based on results performed on wires and microwire materials with general composition FeSiB(CuNb) and obtained by different rapid solidification techniques.

Interplay Between Structure and Interfacial Interactions in Fe‐Gd Synthetic Ferrimagnets

Advanced Electronic Materials, Volume 12, Issue 4, 18 February 2026.
Synthetic ferrimagnets with nearly identical Gd–Fe compositions but different architectures and crystallinity were investigated by element‐resolved microscopy, structural analysis and atomistic spin simulations. The results show that Curie temperature and domain evolution are governed primarily by structural order and interface quality, demonstrating ...
