BP/MoS₂ Van Der Waals Heterojunctions for Self‐Powered Photoconduction

Advanced Optical Materials, Volume 13, Issue 22, August 5, 2025.
A multilayer black phosphorus (BP)/monolayer MoS₂ vertical heterostructure is investigated using four‐probe measurements. The device exhibits rectifying behavior, dominant n‐type transport, low contact resistance, and an interface barrier of 68 meV.

Ist Phenylnitren ein fehlendes Bindeglied in der Bildung polyzyklischer aromatischer Stickstoffheterozyklen?

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.

Cosmological inference with cosmic voids and neural network emulators

Astronomy & Astrophysics
Context. Cosmic voids are a promising probe of cosmology for spectroscopic galaxy surveys due to their unique response to cosmological parameters. Their combination with other probes promises to break parameter degeneracies. Aims.

Extreme Terahertz Nonlinearity of AlGaN/GaN‐Based Grating‐Gate Plasmonic Crystals

Advanced Optical Materials, Volume 13, Issue 21, July 25, 2025.
Plasmonic crystals based on grating‐gated 2D electron gas in AlGaN/GaN heterostructures provide a platform for strong light‐matter interaction. Pump‐probe experiments revealed strong terahertz nonlinearity leading to 45% increase in transmission at a fluence below 350 nJ cm−2.

Pre-equilibrium photons from the early stages of heavy-ion collisions

Journal of High Energy Physics
We use QCD kinetic theory to compute photon production in the chemically equilibrating Quark-Gluon Plasma created in the early stages of high-energy heavy-ion collisions.

Quantifying the degree of hydrodynamic behaviour in heavy-ion collisions [PDF]

EPJ Web of Conferences
Exploiting the first measurements of the same ion species in O+O collisons at RHIC and LHC, we propose an experimentally accessible observable to distinguish whether collective behaviour builds up through a hydrodynamic expansion of a strongly ...

Chemisch Angetriebener Aktiver Transport

Angewandte Chemie, Volume 137, Issue 27, July 1, 2025.
Wir berichten über ein synthetisches System, das chemische Potenzialunterschiede ähnlich biologischen Systemen nutzt, um kleine Moleküle über eine hydrophobe Barriere gegen einen Konzentrationsgradienten zu transportieren. Anstelle einer komplexen Pumpmaschinerie erfolgt der Transport durch die vorübergehende Aktivierung von Transportermolekülen. Unser

Pseudo-scalar meson spectral properties in the chiral crossover region of QCD

Journal of High Energy Physics
Determining the type of excitations that can exist in a thermal medium is key to understanding how hadronic matter behaves at extreme temperatures.
