Frequency‐Dependent Acoustic Reflection Coefficients of Flat Ground Assessed Using the Sonic Boom From the OSIRIS‐Rex Sample Return Capsule Recorded on Free Flying Balloons

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Low frequency sound can travel great distances in planetary atmospheres. When these waves reflect off the air/ground interface, energy may be absorbed or transferred to mechanical waves in the subsurface. This study describes the direct and reflected acoustic wave generated by the re‐entry of the OSIRIS‐REx Sample Return Capsule captured on a ...

Nitrate Photolysis in the Upper Boundary Layer as a Daytime Missing Source of HONO: Revealed by In Situ Airship Measurements and Modeling

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The missing source of nitrous acid (HONO) is a key uncertainty in understanding atmospheric chemistry in the troposphere. Particulate nitrate photolysis has been proposed as a potential source of daytime HONO, but its contribution remains poorly constrained, with even less attention paid to the impact of nitrate aloft. Here, we investigate the

High‐Energy‐Density Redox Flow Batteries: Mechanisms, Design Strategies, and Recent Progress

Chemistry – A European Journal, Volume 32, Issue 24, 23 June 2026.
ABSTRACT The inherent intermittency of energy sources such as solar and wind power hinders the transition to renewable energy, necessitating advanced energy storage solutions. Enhancing energy density is crucial for lowering system costs and enabling large‐scale deployment.

1,1‐and 1,2‐Diborylalkenes: Preparation and Synthetic Applications

Advanced Synthesis &Catalysis, Volume 368, Issue 12, 17 June 2026.
In this review, we highlight recent advances in the synthesis and reactivity of 1,1‐diborylalkenes and 1,2‐diborylalkenes, along with various transformations leading to C‐C, C‐heteroatom, and multicomponent products. By providing a comprehensive and practical resource, this review aims to assist researchers in exploring the synthetic utility of 1,1 and

A Crystalline Ylide‐Stabilized Stibenium Cation

European Journal of Inorganic Chemistry, Volume 29, Issue 17, 17 June 2026.
The isolation of a stibenium cation stabilized by two thiophosphinoyl‐tethered ylide groups is reported. The cation is accessible via salt metathesis of the metalated ylide with SbCl3 and features CSb single bonds, with lone pairs remaining localized at the ylidic carbon atoms.
