Reconfigurable 3D Magnetic Nanoarchitectures

Advanced Functional Materials, EarlyView.
This experimental study confirms that 3D magnetic tetrapods grown by focused electron beam‐induced deposition exhibit sequential, controllable magnetization reversal in the individual nanowire legs. The magnetic state of the nanoarchitecture can be controlled individually, on‐demand, through a variation of the direction and magnitude of the applied ...

Magnetic Field Amplification during Stellar Collisions between Low-mass Stars

The Astrophysical Journal Letters
Blue straggler stars in stellar clusters appear younger and bluer than other cluster members, offering a unique opportunity to understand the stellar dynamics and populations within their hosts.

Blue stragglers as the source of the high-velocity A stars

The Astrophysical Journal, 1988
A quantitative estimate of the contribution of blue stragglers to the stellar population in the solar neighborhood is made, with particular attention to the spatial distribution of early-type stragglers at large distance from the Galactic plane. Blue stragglers are assumed to be created in the disk at a rate consistent with the empirical data from open

Rolling Ultrasharp Microneedle Spheres Enable Topical Delivery of Biologics Through the Skin

Advanced Healthcare Materials, EarlyView.
Rolling ultraminiaturized microneedle spheres (RUMS), created via two‐photon polymerization, unlock effective and painless topical delivery of messenger RNA (mRNA) and drugs through the skin. By gently forming thousands of microscopic pores, RUMS boost skin permeability by up to 100‐fold.

Transitory Tidal Heating and Its Impact on Cluster Isochrones

The Astrophysical Journal
The kinetic energy in tidal flows, when converted into heat, can affect the internal structure of a star and shift its location on a color–magnitude diagram from that of standard models.

Novel 3D‐Printed Biophotonic Scaffold Displaying Luminescence under Near‐Infrared Light for Photopharmacological Activation and Biological Signaling Compound Release

Advanced Healthcare Materials, EarlyView.
Despite significant efforts in developing novel biomaterials to regenerate tissue, only a few of them have successfully reached clinical use. It has become clear that the next generation of biomaterials must be multifunctional. Smart biomaterials can respond to environmental or external stimuli, interact in a spatial‐temporal manner, and trigger ...

Evolution of Mass Functions of Coeval Stars through Wind Mass Loss and Binary Interactions [PDF]

, 2015
Accurate determinations of stellar mass functions and ages of stellar populations are crucial to much of astrophysics. We analyse the evolution of stellar mass functions of coeval main sequence stars including all relevant aspects of single- and binary ...

The “UV-route” to Search for Blue Straggler Stars in Globular Clusters: First Results from the HST UV Legacy Survey [PDF]

, 2017
We used data from the Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters to select the Blue Straggler Star (BSS) population in four intermediate/high density systems (namely NGC 2808, NGC 6388, NGC 6541, and NGC 7078) through a “UV ...

Standalone Integrated Magnonic Devices

Advanced Materials, EarlyView.
A standalone (not requiring external bias magnetic field) and tunable magnonic device is reported with all‐electric input and output, fully integrated on silicon (total footprint of 100 × 150 µm) and 3–8 GHz frequency band. This is achieved by monolithic integration of a CoFeB conduit with RF antennas and an assembly of NiFe and SmCo micromagnets ...
