Molecules that Generate Fingerprints: A New Class of Fluorescent Sensors for Chemical Biology, Medical Diagnosis, and Cryptography

Accounts of Chemical Research, 2023
Conspectus Fluorescent molecular sensors, often referred to as “turn-on” or “turn-off” fluorescent probes, are synthetic agents that change their fluorescence signal in response to analyte binding.

How founders' values enable business model innovation in new ventures: The case of Magnum Photos

Strategic Management Journal, Volume 46, Issue 10, Page 2492-2534, October 2025.
Abstract Research Summary This study explores why and how founders' values lead them to design novel business models. To address these questions, we conducted a historical case study of Magnum Photos, a photo agency whose novel business model revolutionized magazine photography in the mid‐20th century.

Enabling Visible Light Sensitization of YbIII, NdIII and ErIII in Dimeric LnIII/GaIII Metallacrowns through Functionalization with RuII Complexes for NIR‐II Multiplex Imaging

Angewandte Chemie, Volume 137, Issue 3, January 15, 2025.
LnRu‐3 dimeric LnIII/GaIII metallacrows bearing four RuII chromophoric complexes have been synthesized and proved to exhibit characteristic emissions of YbIII, NdIII and ErIII in the NIR‐II region upon excitation with visible light through metal‐to‐ligand charge transfer (MLCT) states.

In Pursuit of the Exceptional: Research Directions for Machine Learning in Chemical and Materials Science.

Journal of the American Chemical Society, 2023
Exceptional molecules and materials with one or more extraordinary properties are both technologically valuable and fundamentally interesting, because they often involve new physical phenomena or new compositions that defy expectations.

The Versatility of Diazirines: Properties, Synthetic and Modern Applications

Chemistry – A European Journal, Volume 31, Issue 43, August 1, 2025.
Diazirines are 3‐membered heterocycles containing two nitrogen atoms connected by a double bond. They possess a multi‐faceted reactivity that holds great potential for organic synthesis. This review discusses their properties, modes of activation, and their many modern uses, underlining their underappreciated versatility: as carbene precursors, but ...

The Halogen Effect in [Cu(NHC)X] Compounds: A Case Study on the Anti‐Leishmania and Antiviral Activity of [Cu(IPr)X]

ChemistrySelect, Volume 10, Issue 31, August 15, 2025.
This study explores how changing halidesfrom Cl to Iinfluences ionic radius, antioxidant activity, and lipophilicity. These shifts significantly impact the biological potency of [Cu(IPr)X] compounds against Leishmania parasites and arboviruses. A strategic tweak in halogen identity paves the way for enhanced therapeutic performance in metal‐based drug ...

Simulating evaporative wet and dry cycles in Gale crater, Mars using thermochemical modeling techniques

Meteoritics &Planetary Science, Volume 60, Issue 8, Page 1704-1720, August 2025.
Abstract The aim of this work is to provide a model‐backed hypothesis for the formation of evaporites—sulfates, borates—in Gale crater using thermochemical modeling to determine constraints on their formation. We test the hypothesis that primary evaporites required multiple wet–dry cycles to form, akin to how evaporite assemblages form on Earth ...

Floral Scent Variation in Cyrtorchis letouzeyi (Orchidaceae) Between Natural Versus Cultivated Environments

Biotropica, Volume 57, Issue 3, May 2025.
Shade houses serve as effective scientific tools for ex situ cultivation and orchid conservation in tropical forests. A comparison of the floral scent chemistry of Cyrtorchis letouzeyi between shade houses and natural populations in Cameroon revealed the same dominant compound, identical qualitative compositions across sites, but variations in emission
