Artificial Spider Silk Fibers with Embedded Magnetite Nanoparticles

open access: yesMacromolecular Materials and Engineering, EarlyView.
Artificial spider silk fibers are endowed with magnetic functionality by incorporating magnetite nanoparticles, with different coating and size, at nominal magnetite concentrations between 0.2 and 20 wt.%. The fibers are robust and ductile. The characteristics of the nanoparticles determine their degree of dispersion in the fibers and are crucial to ...

Binary Fraction in Galactic Star Clusters: FSR 866, NGC 1960, and STOCK 2

open access: yesThe Astronomical Journal
The study of binary stars in different astronomical environments offers insights into the dynamical state of the hosting stellar systems. The binary fraction in fact plays a crucial role in the dynamical evolution of stellar systems, regulating processes

Field population II blue stragglers

open access: yesThe Astrophysical Journal, 1981
Photometry and high-resolution spectra are presented and discussed of metal-poor stars hotter than the turn-off of globular clusters. Very few nonvariable candidates for blue stragglers can be identified One, HD 100363, is probably an old-disk short-period variable.

Rare‐Earth‐Free Iron‐Based Permanent Magnets: Progress, Challenges, and Perspectives

open access: yesMetalMat, EarlyView.
Rare‐earth (RE)‐free iron‐based permanent magnets have gained attention as inexpensive, environmentally friendly alternatives to conventional RE‐based magnets. This review focuses on emerging Fe‐based hard magnets, discussing the fundamental principles governing their permanent magnetism and various examples of Fe‐based systems with emphasis on their ...

Radial TRASE: 2D RF encoding through mechanical rotation and active digital decoupling

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose Two‐dimensional (2D) transmit array spatial encoding (TRASE) previously required four radiofrequency fields; however, interactions between transmit (Tx) array elements caused significant challenges for 2D imaging. Here, we present a low‐cost, 2D radial encoding scheme (Radial TRASE) using a simplified two‐coil array.
