Small, EarlyView.1‐butyl‐4‐methylpyridinium tetrafluoroborate (BMPyBF4) interacts with excess PbI2 during film formation, driving the formation of a low‐dimensional perovskite phase and enabling the self‐organization of a 3D/2D interfacial structure. This molecularly regulated interface suppresses defect‐mediated recombination and facilitates interfacial charge ...

Spectroscopic analysis of bacterial photoreactivation
Photochemistry and Photobiology, Volume 101, Issue 2, Page 494-504, March/April 2025.This study investigates the effectiveness of fluorescence and Raman spectroscopy in detecting bacterial photoreactivation. Fluorescence spectroscopy shows limitations, because the intense fluorescence of tryptophan and tyrosine masks fluorescence emitted by thymine molecules.

Vacuum UV study of photodissociation of CS and C2 [PDF]
, 2021 Photodissociation by ultraviolet (UV) radiation is a key destruction pathway for small molecules in regions where the interstellar UV radiation can penetrate, such as the diffuse molecular clouds, protoplanetary disks, and photon-dominated regions ...

Photochemistry and Photobiology, EarlyView.Thin solid films of pure glycine or alanine (thicknesses ranging from 10 to 700 nm) were prepared on MgF2 windows using a vacuum sublimation/recondensation method. VUV‐UV spectroscopy of these films enabled us to characterize new absorption cross sections for glycine and alanine for VUV‐UV radiations between 120 and 300 nm.

First 20 Years of Orbitrap Mass Spectrometry as the Mainstream Analytical Technique
Mass Spectrometry Reviews, Volume 45, Issue 6, Page 1064-1086, November/December 2026.ABSTRACT This review traces the first 20 years of Orbitrap mass spectrometry as a mainstream high‑resolution and accurate‑mass (HR/AM) technology. It outlines the historical development of the Orbitrap analyzer, the evolution of major instrument families, and the key technological innovations that enabled its widespread adoption. Particular emphasis is

Grain Dynamics In Photodissociation Regions
, 2008 We discuss the forces on grains exposed to anisotropic radiation fields, including the usual "radiation pressure " force and also recoil forces due to photoemitted electrons, photodesorbed hydrogen atoms, and hydrogen molecules which form on ...

Impact of the 1 April 2026 Artemis II Rocket Launch on the Upper Atmosphere: TIMED/GUVI Observations
Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract The NASA Artemis II rocket was successfully launched at 06:35 p.m. ET (22:35 UTC) on 1 April 2026 from the Kennedy Space Center (28°35′28″N 80°39′03″W). The rocket plume caused enhanced Lyman α emission (up to ∼3 kR) observed by TIMED/GUVI on 2–6 April (5 days). Its peak intensity decreased linearly from April 3 at a rate ∼740 R/day.
