Chemical Profiling and Biological Activity of Copaiba Oil‐Resin Samples and Development of HPLC‐DAD Method for the Analysis of β‐Caryophyllene

open access: yesBiomedical Chromatography, Volume 40, Issue 5, May 2026.
ABSTRACT The Copaifera species are traditionally used for their anti‐inflammatory, antiseptic and healing properties. The objective of this study was to compare the chromatographic profiles of seven samples of copaiba oil‐resin with respect to chromatographic and physicochemical properties and to evaluate their biological activities.

Selective Ion‐Blocking Strategy for Stabilizing Perovskite Tandem Solar Cells

open access: yesAdvanced Energy Materials, Volume 16, Issue 13, 1 April 2026.
A selective ion‐blocking Li─T interlayer is introduced at LiF‐passivated perovskite interfaces to suppress fluorine diffusion while preserving the beneficial interfacial passivation of LiF. This ion‐blocking strategy markedly improves the long‐term operational stability of both single‐junction and monolithic all‐perovskite tandem cells under continuous
