Shear Properties of Carbon Fiber/Phenolic Resin Composites Heat Treated at High Temperatures
Journal of Aerospace Technology and Management, 2016 Carbon fiber/phenolic resin composites have long been used as ablative materials in rocketry. Ablation is a complex multiscale problem where radiative and convective heating leads to the pyrolysis of phenolic resin matrix, resulting in the formation of a

SYNTHESIS OF A BORON MODIFIED PHENOLIC RESIN. doi: 10.5028/jatm.2010.02027610
Journal of Aerospace Technology and Management, 2011 Phenolic resin has long been used as matrix for composites mainly because of its flame retardant behavior and high char yield after pyrolysis, which results in a self supporting structure.

The Red Queen unveils the sexual and mating strategies of flowers
Journal of Ecology, Volume 114, Issue 5, May 2026.Although the conventional wisdom is that floral traits of plants evolved in concert with their mutualistic pollinators, here we showed that several key sexual and mating traits of plants, which modulate their outcrossing strategy, evolved in response to the pressure exerted by their antagonistic insect herbivores.

May I pick your brain? Local minds as living cadastres in a Portuguese eleventh‐century lawsuit
Early Medieval Europe, Volume 34, Issue 2, Page 231-253, May 2026.In the context of a dispute with the monastery of Lorvão, in the late eleventh century, the monks of Vacariça, near Coimbra (modern Portugal), carried out a field enquiry in the village of Recardães. This was part of a failed attempt to repossess a number of land plots that they claimed were theirs, but had lost control of.
