Advanced Quantum Technologies, Volume 9, Issue 1, January 2026.We demonstrate that deterministic in situ electron‐beam lithography enables precise integration of single quantum dots into compact circular Bragg grating resonators, achieving high extraction efficiency with only 3–4 rings. Across 95 devices, the approach delivers >$>$90% alignment yield and bright, narrow‐linewidth single‐photon emission, providing a

Advanced Engineering Materials, Volume 27, Issue 24, December 2025.Primary phases and a fatigue crack are studied in a forged blank of an aluminum alloy using synchrotron and laboratory X‐ray computed tomography. To image the crack, the fatigue test is interrupted, and a static tensile load is applied to open the crack.

Evidence for Low Extinction in Actively Star Forming Galaxies at z$>$6.5 [PDF]
, 2012 We present a search for the [CII] 158micron fine structure line (a main cooling line of the interstellar medium) and the underlying far-infrared (FIR) continuum in three high-redshift (6 ...

Nonlinear Transmission of Strong THz‐Electric Fields Through Thin Gold Films
Advanced Optical Materials, Volume 13, Issue 35, December 12, 2025.Gold is is the prime metal for imaging THz radiation. This study demonstrates that the interaction of strong THz pulses with gold becomes nonlinear at certain peak THz‐electric field strengths. The strong fields change the electron density of states which contributing to the absorption of the propagating THz pulse.

Jupiter's X‐ray Aurorae. A High Signal Spectral Analysis of the 0.24–1.40 keV Energy Range
Journal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.Abstract Jupiter's X‐ray auroras are predominantly produced by precipitating energetic heavy ions. Recent results suggest a connection between the pulsation rate of these ion aurorae and the pulsation rate of magnetospheric waves. Using remote X‐ray observations and results from in situ measurements from the Juno Jupiter Energetic particle Detector ...

The Formation of Low-Mass-Protostars and Proto-Brown Dwarfs [PDF]
, 2007 The formation of low-mass protostars and especially of brown dwarfs currently are ``hot topics'' in cool star research. The talks contributed to this splinter session discussed how low in mass and how low in luminosity objects might exist, if these ...

N‐Heterocyclische Carbene auf einem III‐V‐Halbleiter: Von Kettenbildung zu geordneten Monolagen
Angewandte Chemie, Volume 137, Issue 46, November 10, 2025.Die Funktionalisierung von GaAs, einem III‐V‐Halbleiter, mit N‐heterocyclischen Carbenen wird in einem multidisziplinären experimentellen und theoretischen Ansatz demonstriert. Es werden geordnete Monolagen erreicht, die aus Ketten von Molekülen bestehen, welche kovalent an die Oberfläche gebunden sind und die Oberflächeneigenschaften stark verändern ...

Angewandte Chemie, Volume 137, Issue 31, July 28, 2025.Ein neuer Bildungsweg für polyzyklische aromatische Stickstoffheterozyklen (PANH) wurde gefunden. Die Reaktion von Phenylnitren mit dem Propargylradikal führt zu Chinolin und belegt, dass Nitrene geeignete Vorläufer zum Einbau von Stickstoffheteroatomen sind.

Triggered fragmentation in gravitationally unstable discs: forming fragments at small radii
, 2013 We carry out three dimensional radiation hydrodynamical simulations of gravitationally unstable discs using to explore the movement of mass in a disc following its fragmentation. Compared to a more quiescent state before it fragments, the radial velocity
