Savannah and Boreal Biomass Burning as a Source for Cloud Condensation Nuclei

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Aerosol particles emitted in wildfires can contribute to radiative forcing via aerosol‐cloud interactions and by directly interacting with solar radiation. Wildfire emissions increase the concentration of cloud condensation nuclei (CCN) in the atmosphere and thus affect cloud properties (e.g., cloud brightness).

Tuning Circular Dichroism and Circularly Polarised Luminescence in Single Crystals of a Perylene Diimide Macrocycle

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.
The circular dichroism (CD) and circularly polarised (CPL) of a bis‐perylene diimide macrocycle are measured in single crystals. These chiroptical properties are tuned by the macrocycle's π–π stacking interactions in the solid‐state. Abstract Chiral materials that manipulate circularly polarised light have burgeoning applications across optoelectronics,

Photopumped infrared vertical-cavity surface-emitting laser

Applied Physics Letters, 1996
The feasibility of a photopumped infrared vertical-cavity surface-emitting laser (VCSEL) based on CdHgTe alloys is demonstrated. The structure of the VCSEL consists of a 16.5-period Cd0.4Hg0.6Te/Cd0.75Hg0.25Te bottom Bragg reflector and a 3λ/4 thick Cd0.75Hg0.25Te cavity, containing a 100-nm-thick well, grown by molecular beam epitaxy.
