Visible Light-Harvesting Dinuclear Chromium(III) Complex with Anthracene-Based Phosphorescence for Photon Upconversion and Photocatalysis

Abstract Luminescent 3d3 chromium(III) complexes are emerging as highly attractive, earth-abundant alternatives to precious 4d or 5d metal complexes in photophysical and photochemical applications. However, the Laporte-forbidden nature of their d–d transitions in the visible regi...

Recyclable and Degradable Covalent Adaptable Polymer Networks ( CANs ) Based on Dynamic Thiol–Yne Reactions

ABSTRACT Covalent adaptable networks (CANs) have been introduced as an alternative to classical thermosets. The presence of dynamic covalent bonds can be utilized to enable (re‐)processability and, consequently, the recyclability of these polymer networks. Within this context, we...

Conditional deep generative modeling of blood-based infrared spectra enables controlled in-silico phenotyping studies

Abstract Infrared molecular fingerprinting of blood offers a scalable, minimally invasive window into human physiology, but limited follow-up, imbalanced cohorts, and restricted access to diverse phenotypes constrain systematic studies. Here, we introduce a conditional deep gener...

Intrinsic OPTIR imaging and spectroscopy enable label-free monitoring of viral infection in living cells

Abstract Resolving biochemical signatures associated with viral infection progression within individual living cells, without introducing fluorescent labels that demand genetic accessibility and may perturb the process under study, remains a challenge for conventional optical app...

Large-scale benchmarking of prokaryotic annotation tools across thousands of species

Abstract Background Genome annotation is an important step in deriving functional meaning from prokaryotic sequencing data, yet systematic evaluations guiding tool selection are lacking. We present the first large-scale investigation of four prominent open-source annotation tools...

Color Symmetry Breaking in a Nonlinear Optical Microresonator

ABSTRACT Spontaneous symmetry breaking leads to diverse phenomena across the natural sciences, from the Higgs mechanism in particle physics to superconductors and collective animal behavior. In photonic systems, the symmetry of light states can be broken when two optical fields i...
