Small but mighty: Impact hazards from iron Near‐Earth Objects

Meteoritics &Planetary Science, Volume 61, Issue 2, Page 224-240, February 2026.
Abstract Small asteroids can impact Earth unexpectedly, as demonstrated by the Chelyabinsk event in 2013. The warning times are likely to be short, and the first tools for fast hazard predictions have been developed in the last years for encounters with rocky or cometary objects, which quickly fragment in the atmosphere and cause airbursts. However, in

Operating condition and geometry effects on low-frequency afterburner combustion instability in a turbofan at altitude [PDF]

Three afterburner configurations were tested in a low-bypass-ratio turbofan engine to determine the effect of various fuel distributions, inlet conditions, flameholder geometry, and fuel injection location on combustion instability.

Southern Ocean Sulfate Aerosol Sources Quantified From Sulfur Isotopes in Antarctic Ice Cores

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The Southern Ocean has emerged as a key region for constraining aerosol‐climate interactions due to its relatively low anthropogenic influence. Sulfate is an important aerosol over the Southern Ocean, and models suggest dimethyl sulfide (DMS) is the largest source of sulfate during summer.

Synthesis of DOPO‐Containing Melamine Flame Retardant and Its Effect on the Flame‐Retardant Properties of Waterborne Polyurethane

Journal of Applied Polymer Science, Volume 143, Issue 3, January 15, 2026.
DOPO‐containing melamine flame retardants improve the flame retardancy, droplet resistance and mechanical properties of WPU. ABSTRACT To improve the flame retardancy of waterborne polyurethane (WPU), two novel DOPO‐containing melamine‐based flame retardants were synthesized by combining Schiff bases (derived from p‐hydroxybenzaldehyde ...
