Nascent Extracellular Matrix Converts Biomaterial Cues into Cell Fate Decisions

open access: yesAdvanced Science, EarlyView.
This study uncovers a tri‐directional interplay among cells, hydrogels, and their nascent extracellular matrix. Hydrogel norbornene modification alters CD44‐mediated cell–hydrogel interactions, which shape nascent matrix deposition, composition, and spatial organization.

Electron Donor–Acceptor Complex Catalysis in Synthetic Chemistry

open access: yesAngewandte Chemie, EarlyView.
Electron donor–acceptor (EDA) complexes are moving beyond stoichiometric photoactivation toward catalytic platforms for radical generation. Productive EDA catalysis requires coordinated donor–acceptor association, charge‐transfer excitation, radical reactivity, and vcatalyst turnover.

Machine Learning Potential for Calcium Silicate Hydrates With Broad Compositional and Structural Diversity

open access: yesAdvanced Science, EarlyView.
Existing machine learning potentials remain limited in their ability to generalize across the broad chemical and structural variability of C–S–H. Here, a representative DFT‐labeled dataset is constructed through large‐scale model generation, redundancy‐controlled screening, first‐principles optimization, and targeted sampling of non‐equilibrium ...

Phosphine Coordination to Ce, Nd, Np, and Pu in ArBiAMPtBu‐Supported Complexes and Their 2H and 13C Isotopologues

open access: yesAdvanced Science, EarlyView.
A dianionic ligand designed to encourage metal‐phosphine coordination—bis((3,5‐dimethylphenyl)amidomethyl)tertbutylphosphine (ArBiAMPtBu)—was employed in the synthesis of paramagnetic complexes of Ce, Nd, Np, and Pu, producing MI(ArBiAMPtBu)(thf)3.

Cobalt‐Catalyzed C─N Bond Formation via Metal‐Hydride Hydrogen Atom Transfer (MHAT)

open access: yesAngewandte Chemie, EarlyView.
Cobalt‐catalyzed metal‐hydride hydrogen atom transfer (Co‐MHAT) converts simple alkenes into C─N bonds under mild, near‐neutral conditions. A shared Co─H‐initiated radical/organocobalt intermediate is channeled into radical trapping, radical‐polar crossover, or radical ligand transfer, unifying hydroamination, hydroazidation, hydroamidation, and remote

Physiologically Based Simulations of Deuterated Glucose for Quantifying Cell Turnover in Humans

open access: yesFrontiers in Immunology, 2017
In vivo [6,6-2H2]-glucose labeling is a state-of-the-art technique for quantifying cell proliferation and cell disappearance in humans. However, there are discrepancies between estimates of T cell proliferation reported in short (1-day) versus long (7 ...

Spatiotemporal Regulation of Hierarchical Assembly of Hydroxyapatite for Enamel Remineralization

open access: yesAdvanced Science, EarlyView.
Biomimetic repair exhibits unique advantages for enamel regeneration compared with conventional clinical treatments. An enzymatic mineralization system (EMS) is developed, where the resulting HAP nanorods hierarchically assemble into a highly ordered structure on the enamel surface through the spatiotemporal modulation of interfacial energies of ...

Controlled Hydrogen Delivery by Single‐Atom Ru Accelerates Electrocatalytic Ammonia Synthesis

open access: yesAngewandte Chemie, EarlyView.
Single Ru atoms anchored on Co3O4 guide reactants along a hydrogen‐rich surface pathway, enabling efficient and selective conversion of NO to NH3. By linking atomic design to catalytic performance, this strategy clarifies the reaction mechanism and offers a versatile platform for engineering oxide catalysts for electrochemical ammonia synthesis ...

Targeting Macrophage STING O‐GlcNAcylation via Small‐Molecule Allosteric Modulation for Psoriasis Therapy

open access: yesAdvanced Science, EarlyView.
Paeoniflorin allosterically targets the STING cyclic dinucleotide‐binding domain, stabilizes an inactive open conformation, and disrupts STING–OGT interaction to reduce Thr229 O‐GlcNAcylation and downstream signaling. This mechanism restrains myeloid STING activation, alleviates psoriasis‐like inflammation, and is supported by analyses of patient ...
