An Explicit M1 Radiation-hydrodynamics Scheme for 3D Protostellar Evolution

The Astrophysical Journal
We present a radiation-hydrodynamics (RHD) scheme that enables 3D simulations resolving both protostellar interiors and their surrounding accretion flows within a single framework, to clarify how a protostar evolves while interacting with the accretion ...

Single‐Chromophore Homojunction Organic Solar Cells: A Path to Simplicity and Efficiency

Advanced Materials, EarlyView.
This perspective discusses how the intrinsic optoelectronic properties of organic semiconductors, their molecular packing in the solid‐state, and internal energetic gradients within a device can enable free‐charge carrier generation in homojunction organic solar cells.

Radiative forcing since preindustrial times due to ozone change in the troposphere and the lower stratosphere [PDF]

, 2006
Changes in atmospheric ozone have occurred since the preindustrial era as a result of increasing anthropogenic emissions. Within ACCENT, a European Network of Excellence, ozone changes between 1850 and 2000 are assessed for the troposphere and the lower ...

Transparent Perovskite Light‐Emitting Diodes with Conductive Oxide Top Electrodes

Advanced Materials, EarlyView.
Transparent perovskite light‐emitting diodes (TrPeLEDs) enable simultaneous display and transparency, expanding application possibilities. Using a metal oxide buffer layer and pulsed laser deposition, TrPeLEDs with diverse compositions and architectures are demonstrated.

exoALMA. XVI. Predicting Signatures of Large-scale Turbulence in Protoplanetary Disks

The Astrophysical Journal Letters
Turbulent gas motions drive planet formation and protoplanetary disk evolution. However, empirical constraints on turbulence are scarce, halting our understanding of its nature.

SImulation of the epoch of reionziation : radiative transfer

, 2009
La raie hyperfine à 21-cm de l'hydrogène atomique émise dans l'univers à grand redshift (6 < z < 20) permettra de sonder une nouvellère de la cosmologie, l'époque de la réionisation (EoR). Elle fournira des informations plus détaillées, moins ambigües et plus complètes en 3D que les autres observations possibles de l'EoR (comme les raies d'absorption ...

n‐Type Polymer Radio Frequency Rectifiers Operating at 18.5 GHz

Advanced Materials, EarlyView.
Combining an n‐doped polymer semiconductor with wafer‐scale asymmetric planar electrodes featuring work function‐engineered contacts yields radio‐frequency diodes and rectifying circuits operating at up to 18.5 GHz. The devices combine scalable manufacturing with an operating frequency previously unattainable by large‐area organic electronics ...
