Using the Photostationary State of Arylazopyrazoles to Control Phase Transitions of Liquid Crystals

open access: yesAdvanced Functional Materials, EarlyView.
A series of new arylazopyrazole photoswitches is designed as dopants for liquid crystalline materials. Unprecedented, the distribution of photoisomers at the photostationary state upon irradiation with light of specific wavelengths (365, 460, 520 nm) is used to control the liquid crystalline phase transitions under isothermal conditions, including ...

Stellar Evolution Through the Red Supergiant Phase

open access: yesGalaxies
Massive stars less massive than ∼30 M⊙ evolve into a red supergiant after the main sequence. Given a standard IMF, this means about 80% of all single massive stars will experience this phase.

Electron–Matter Interactions During Electron Beam Nanopatterning

open access: yesAdvanced Functional Materials, EarlyView.
This article reviews the electron–matter interactions important to nanopatterning with electron beam lithography (EBL). Electron–matter interactions, including secondary electron generation routes, polymer radiolysis, and electron beam induced charging, are discussed.

Hyperaccretion-driven Relativistic Jets from Massive Collapsars in Active Galactic Nucleus Disks

open access: yesThe Astrophysical Journal
The observable characteristics of gamma-ray bursts embedded in the accretion disk of active galactic nuclei (AGNs) are mainly determined by the jet propagation within the disk.
