A Comparison of Polarization Observables in Electron Scattering from the Proton and Deuteron

open access: yes, 1997
Recoil proton polarization observables were measured for both the p($\vec {\rm e}$,e$^\prime\vec{\rm p}\,$) and d($\vec {\rm e}$,e$^\prime\vec{\rm p}\,)$n reactions at two values of Q$^2$ using a newly commissioned proton Focal Plane Polarimeter at the M.

Engineering Active Metal and Nonmetal Sites in Porous Structures of Metal‐Hydroxide Clusters for Enhanced D2/H2 Uptake and Separation

open access: yesAdvanced Science, EarlyView.
Two supramolecular assembly frameworks, constructed from metal‐hydroxide clusters, are synthesized via coordination‐driven self‐assembly mediated by Co2+ and Cu2+ metal centers. One of them demonstrates exceptional D2 and H2 uptake capabilities, achieving the second‐highest uptake capacity for D2.

Superprotonic Conduction in Donor Co‐Doped Perovskites

open access: yesAngewandte Chemie, EarlyView.
Ceramic proton conductors are promising materials for various applications such as fuel cells. Here, we report superprotonic conduction of BaSc0.8Mo0.1W0.1O2.8 created by donor Mo/W co‐doping into BaScO2.5 (e.g., 10−2 S cm−1 at 193 °C). The high proton conductivity is attributed to high carrier concentration and mobility.

Giant Isotope Effect in Metal–Organic Frameworks Boosts Unprecedented Photo‐ and Radio‐Luminescence Enhancement

open access: yesAdvanced Science, EarlyView.
Deuterated MOFs in this work exhibited unprecedented giant luminescence isotope effect via O─H oscillator suppression, achieving maximal solid‐state materials emission enhancement. This yields significantly improved X‐ray detection sensitivity and imaging resolution, marking the first integration of MOFs with isotopic luminescence and opening new ...

Structural Basis of the Membrane Association by the Conserved RocS Membrane‐Targeting Sequence in Streptococcus

open access: yesAdvanced Science, EarlyView.
Chromosome segregation in Streptococcus pneumoniae depends on RocS, a bitopic protein whose membrane‐anchoring mechanisms were unclear. Using NMR and AFM, this study reveals that the widely conserved RocS anchor binds to membranes via a conserved kink‐helix motif which inserts into lipid nanodomains.

Nonheme Fe Enzyme‐Catalyzed Enantiodivergent Nitrogen Migration: Directed Evolution and Computational Study of Isopenicillin N Synthases for Biocatalytic Synthesis of Arylglycines

open access: yesAngewandte Chemie, EarlyView.
Nonheme Fe enzyme isopenicillin N synthase was reprogrammed and evolved as an efficient nitrogen migratase IPNSNim, converting diverse azanyl esters to valuable l‐arylglycines with up to 16 000 TTN and 97:3 e.r. IPNSNim and ACCONim allowed enantiodivergent preparation of both l‐ and d‐arylglycines.

Lattice Carbon‐Mediated Ultralow‐Barrier C–C Coupling for Selective CO Electroreduction to Ethylene

open access: yesAdvanced Science, EarlyView.
Combined DFT and molecular dynamics simulations reveal that while the lattice carbon at the MXene edge cannot directly bind CO2 to form ethylene, it acts as an active center to promote C─C coupling between adjacent *CO intermediates for ethylene production.
