Structural Insights Into CO2 Transport Pathways in a W‐Formate Dehydrogenase: Structural Basis for CO2 Reduction

open access: yesAngewandte Chemie, EarlyView.
Integrated structural analysis of N. vulgaris formate dehydrogenase AB, an enzyme with applications in climate change mitigation, is reported. The substrate/product diffusion pathways were fully mapped, and a retention site was identified that transiently holds substrates and has a key role in CO2‐reducing activity.

Artificial Intelligence Predictions in Huge Chemical Spaces: Chiroptical Properties of [6]‐helicene Family

open access: yesAdvanced Science, EarlyView.
This study shows that a local, data‐driven AI model can accurately predict diverse optical and chiroptical properties of [6]helicenes using information from close structural neighbours. Combined with genetic algorithms, it enables inverse design for tailored properties, establishing practical structure–property rules for efficient molecular discovery ...

Orbital‐Selective Modulation of Spatial pz‐s Hybridization for Enhanced Photocatalytic H2 Evolution: Insights From NiSe@ReS2+x Cocatalyst

open access: yesAngewandte Chemie, EarlyView.
Spatial orbital‐selective modulation engineering is proposed as a strategy to optimize cocatalyst design, enhance photocatalytic activity, and provide novel insights into the interactions between active sites and adsorbates, as well as catalytic mechanisms.

In Situ Measurement of Oxygen Vacancy Dynamics and Surface Exchange Reactions in Oxide Electrode under Solid Electrochemical Cell Operating Conditions

open access: yesAdvanced Energy Materials, EarlyView.
This study establishes an in situ electrochemical framework using dense bulk electrodes to identify defect chemistry and surface kinetics. While oxygen vacancy concentration is derived via bias modulation, surface exchange coefficients are quantified at open circuit voltage conditions to isolate kinetics.

Bayesian Optimization Guiding the Experimental Mapping of the Pareto Front of Mechanical and Flame‐Retardant Properties in Polyamide Nanocomposites

open access: yesAdvanced Intelligent Discovery, EarlyView.
Bayesian optimization enabled the design of PA56 system with just 8 wt% additives, achieving limiting oxygen index 30.5%, tensile strength 80.9 MPa, and UL‐94 V‐0 rating. Without prior knowledge, the algorithm uncovered synergistic effects between aluminum diethyl‐phosphinate and nanoclay.

Maximal operators associated with Generalized Hermite polynomials and function expansions [PDF]

open access: yes, 2013
We study the weak and strong type boundedness of maximal heat?diffusion operators associated with the system of generalized Hermite polynomials and with two different systems of generalized Hermite functions. We also give a necessary background to define
