Cross‐stage single‐cell and spatial metabolome analyses reveal periderm specialization and tanshinone biosynthesis in Salvia miltiorrhiza roots

New Phytologist, EarlyView.
Biosynthesis and accumulation of tanshinones in the periderm of Salvia miltiorrhiza during secondary root growth. Summary Perennial herbs develop long‐lived roots that undergo repeated cycles of secondary growth, during which the periderm functions as a protective barrier and a major site of specialized metabolite accumulation.

Advances in organic UV filters for sunscreens over the past decade

Photochemistry and Photobiology, EarlyView.
Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...

Multimodal Transformer Fusion of PTR‐ToF‐MS Volatiles and Targeted Non‐Volatile Metabolites Enables Data‐Driven Grading of Baimudan White Tea

Rapid Communications in Mass Spectrometry, Volume 40, Issue 18, 30 September 2026.
ABSTRACT Rationale Commercial grading of Baimudan white tea still relies largely on sensory evaluation and would benefit from a rapid, objective analytical approach. This study investigated whether PTR‐ToF‐MS volatile fingerprints combined with targeted non‐volatile metabolite measurements could support data‐driven grading of four official Baimudan ...

Polysilane‐Supported Nickel as an Efficient Catalyst for the Hydrogenation of Aromatic Compounds†

Chinese Journal of Chemistry, Volume 44, Issue 14, Page 2277-2282, 15 July 2026.
A Ni/Si catalyst obtained from the reaction of poly(monohydro)silane with Ni(cod)2 serves as an effective heterogeneous catalyst for the hydrogenation of arenes under reaction conditions that are significantly milder than those required for conventional nickel‐based catalysts such as Raney nickel.

Phosphate‐Terminated Nb2C MXene as Efficient Catalyst for the Transformation of Glucose Into 5‐Hydroxymethylfurfural With 3077 h−1 Turnover Frequency

ChemSusChem, Volume 19, Issue 13, 14 July 2026.
A new phosphate‐terminated Nb2C MXene has been developed as an efficient heterogeneous catalyst to convert glucose into 5‐hydroximethylfurfural. Characterization of the Nb2C‐PO4 catalyst has proven the presence of phosphate and the integrity of the MXene laminar structure.
