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

Exciton Binding Energy of Phosphorescent Emitter Molecules in Organic Light‐Emitting Diodes
Advanced Functional Materials, EarlyView.Energy level alignment is key to efficient OLED design, yet determining LUMO energies remains challenging. A methodology based on field‐induced dissociation and kinetic Monte Carlo simulations is presented to extract LUMO energies of iridium‐based phosphorescent emitters from their exciton binding energy.

Transitory Tidal Heating and Its Impact on Cluster Isochrones
The Astrophysical JournalThe 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.

Advanced Functional Materials, EarlyView.We use scanning nitrogen vacancy magnetometry to directly image the weak in‐plane magnetic moments in mixed phase BiFeO3 at the nanoscale and quantify the local magnetic moments to be 18.8±2.0 μB/nm2 in the rhombohedral‐like phase and 1.5±0.6 μB/nm2 in the well‐known non‐magnetic tetragonal‐like phase.

Advanced Functional Materials, EarlyView.This work explores the possibility to design stable periodic magnetization textures by transforming a 2D film into a rolled‐up 3D architecture and back. In case of an isotropic exchange‐biased layer architecture, the magnetization encoded in the 3D state evolves into a spin‐spiral pattern with controlled periodicity after unrolling.

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine
Advanced Materials, EarlyView.A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Chemically peculiar candidates in 18 Milky Way globular clusters
Astronomy & AstrophysicsContext. Recent discoveries show that chemically peculiar (CP) stars also reside in globular clusters (GCs). The channels leading to chemical peculiarity are, however, still under discussion. Aims.

The Blue Straggler Star population in NGC6229
The Monthly Notices of the Royal Astronomical Society , 2012 We have used a combination of high-resolution Hubble Space Telescope Wide Field Planetary Camera 2 and wide-field ground-based observations in ultraviolet and optical bands to study the blue straggler star (BSS) population of the outer halo globular cluster NGC 6229 over its entire radial extent.

Advanced Materials, EarlyView.We demonstrate a neuromorphic synapse in 2D Fe3GaTe2 flakes. The device operates via a current‐driven transformation from a skyrmion‐lattice to a stripe‐domain state, yielding a linear anomalous Hall resistance response with a tunable slope to enable multiply‐accumulate operations. Simulations confirm its viability in artificial neural networks.
