Ratios of Extinction Coefficient, Mass, and Surface Area to Backscatter Coefficient and Mass to Extinction Coefficient Derived From Balloon‐Borne Stratospheric Aerosol Size Distribution Measurements From 1989–2025

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract In situ measurements of stratospheric aerosol are the only measurements that provide sufficient detail to determine aerosol number, size, surface area, volume/mass, and effective radius; however, these measurements are limited in space and time.

Dual Variational Problems and Action Principles for Chen–Lee and Hopf–Langford Systems

Mathematical Methods in the Applied Sciences, Volume 49, Issue 4, Page 2456-2462, 15 March 2026.
ABSTRACT We describe the construction of dual variational principles and action functionals for nonlinear dynamical systems using a methodology based on the dual Lagrange multiplier formalism and a convex optimization approach, to derive families of dual actions that correspond to the given nonlinear ordinary differential system.

Double Helical Plasmonic Antennas

Advanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Sustainable Framework for Thermoelectric Inorganic‐In‐Organic Superlattices With High Power Factor and Selective P‐ or N‐Type Doping

Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
By multilayering poly(3,4‐ethylenedioxythiophene):polystyrene sulfonate with metal nanolayers into a superlattice structure, we report an enhancement to the thermoelectric performance of two orders of magnitude, achieving a peak power factor of 2800 µW m−1 K−2.

Low‐intensity prescribed fire has no immediate impact on soil physical and chemical properties or enzymatic activity in the Post Oak Savanna ecoregion, Texas, USA

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract The historic development of the Post Oak Savanna ecoregion in Texas, USA, was shaped by natural wildfires. However, wildfire suppression has caused an increase in encroaching woody species. To address this issue, land management strategies incorporate prescribed fire (PF) for the control of encroaching species.
