Crossover operators to control size growth in linear GP and variable length GAs [PDF]

open access: yes, 2008
In various nuances of evolutionary algorithms it has been observed that variable sized genomes exhibit large degrees of redundancy and corresponding undue growth. This phenomenon is commonly referred to as bloat. The present contribution investigates the

In Situ Formation of a Highly Selective Nickel Single Atom Catalyst for Electrochemical CO2 Reduction to CO

open access: yesAdvanced Materials, EarlyView.
Development of a novel method for synthesizing Ni single atom catalysts for highly selective electrochemical CO2 reduction in situ. This catalyst achieves 100% selectivity for CO and is formed in an industrially relevant cell architecture. Using post‐mortem XRD, STEM, and EDS and operando XAS, the identity of the active site and the mechanism behind ...

Layered Spin‐Crossover Metal‐Organic Frameworks for Light‐Induced Control of Two‐Dimensional Quantum Materials

open access: yesAdvanced Materials, EarlyView.
Spin‐crossover metal‐organic frameworks (SCO‐MOFs) provide a route to control the electronic and magnetic properties of two‐dimensional quantum materials. By integrating a layered SCO‐MOFs with graphene, CrSBr, and NbSe2 nanodevices, thermally and light induced spin transitions induce strain that reversibly modulates charge transport, magnetic memory ...

Adaptive Supramolecular Interactions Govern Redox‐Active Molecules in Aqueous Redox Flow Batteries

open access: yesAdvanced Materials, EarlyView.
Adaptive supramolecular interactions overcome the solubility‐stability trade‐off in aqueous redox flow batteries. Hydrophobic anions disrupt intrinsic π–π stacking to enable high solubility, while redox‐state‐dependent spin pairing and cation coordination dynamically stabilize reactive intermediates during operation.

A building-block Royal Road where crossover is provably essential

open access: yes, 2007
One of the most controversial yet enduring hypotheses about what genetic algorithms (GAs) are good for concerns the idea that GAs process building-blocks.

Understanding Operando Water Management in Hydroxide‐Exchange‐Membrane Fuel Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
Effective water management is vital for high‐performance hydroxide‐exchange‐membrane fuel cells. Using a custom water‐flux station, this study quantifies how membrane thickness, microporous layers, and operating conditions dictate internal water transport.

Binder‐Free Direct Ink Writing of Li6.4La3Zr1.4Ta0.6O12 Garnet Electrolytes for All‐Solid‐State Batteries

open access: yesAdvanced Materials Interfaces, EarlyView.
Polymer binders and thick pressed LLZTO pellets limit all‐solid‐state battery integration through grain‐boundary carbon and high ohmic losses. A binder‐free capillary suspension ink is direct‐ink‐written and sintered into 254 μm$\mu{\rm m}$, 95.8%‐dense Ta‐stabilized LLZTO with 17.3 mS cm−1$\text{cm}^{-1}$ bulk conductivity, enabling thinner ...
