Fused Ring Engineering Induced Topology Control in Covalent Organic Frameworks: Unlocking Promoted Photocatalytic H2O2 Production and Selective Methane Oxidation

open access: yesAngewandte Chemie, EarlyView.
By modulating the topological structures of two N‐heterocycle‐based covalent organic frameworks, Phen‐TTA with a kgd‐v topology exhibits narrower optical bandgap, lower exciton binding energy, and faster charge‐carrier kinetics compared to O‐TTA with an hcb topology.

Sensing and Filtering Environmental Fluctuations: The Case of Biomolecular Condensates in Plants

open access: yesAdvanced Science, EarlyView.
The diversity of plant condensates reflects constraints of sessile organisms to coordinate postembryonic development with environmental adaptation. This review examines how plants employ condensates to integrate temperature, light, redox, and nutrient signals.

Recent Trends in Metabolomics by NMR Spectroscopy

open access: yesAngewandte Chemie, EarlyView.
AI tools were applied to analyze more than 5 000 publications indexed in Scopus (2018–2025), identifying key trends and research directions in NMR‐based metabolomics. The artificial intelligence‐assisted workflow classified papers into six main fields of application, human health, food and nutrition, veterinary science, plants, environment, and ...

Lunar‐Based Photothermal CO2 Reduction Strategy: Self‐Evolving Transient Active Interface and Band Engineering

open access: yesAdvanced Science, EarlyView.
A self‐evolving Pd/Ov‐FeTiO3 photothermal catalyst, inspired by lunar soil, enables efficient extraterrestrial CO2 conversion. The formation of transient active interfaces and oxygen vacancies extends light absorption to the infrared range and optimizes electron transfer.

π‐Enlargement in Porphyrin Macrocycles at Interfaces

open access: yesAngewandte Chemie, EarlyView.
On‐surface synthesis of a 20‐π free‐base expanded porphyrin, by depositing onto a hot Ag(111) substrate an 18‐π free‐base precursor equipped with ‐CF3 functional groups ABSTRACT Porphyrins are essential heteroatomic macrocycles, fundamental to both biological systems and advanced technology.

Dissecting long-term adjustments of photoprotective and photo-oxidative stress acclimation occurring in dynamic light environments

open access: yesFrontiers in Plant Science, 2016
Changes in light intensity directly affect the performance of the photosynthetic apparatus. Light energy absorbed in excess of cells’ needs leads to production of reactive oxygen species and photo-oxidative damage.

SIMULATING OZONE EFFECTS ON FOREST PRODUCTIVITY: INTERACTIONS AMONG LEAF‐, CANOPY‐, AND STAND‐LEVEL PROCESSES [PDF]

open access: yes, 1997
Ozone pollution in the lower atmosphere is known to have adverse effects on forest vegetation, but the degree to which mature forests are impacted has been very difficult to assess directly.

Quantum Nanomedicine and Quantum Biomaterials

open access: yesAdvanced Science, EarlyView.
In this perspective, we define quantum nanomedicine and quantum biomaterials as a paradigm that harnesses quantum effects in nanomedicine and biomaterials, including quantum superposition, quantum coherence, quantum tunneling, topological quantum effects, and spin polarization, to achieve either spatiotemporally precise modulation of physiological ...

Minimal ATP‐Independent N2‐Reducing Systems Defined by L‐Cluster‐Bound Nitrogenase Assembly Platforms

open access: yesAngewandte Chemie, EarlyView.
Association of the L‐cluster with the nitrogenase assembly proteins NifEN (NifENL) or NifB (NifBL) intrinsically endows these proteins with N2‐reducing activity, enabling in vitro N2‐reduction by NifENL and NifBL when supplied with chemical reductants or photoexcited quantum dots while supporting in vivo N2‐fixation in NifENL‐ and NifENL‐expressing ...
