Structure-Dependent CO and NO Oxidation over Bimetallic PtPd/Al2O3 Catalysts: Impact of Pt–Pd Mixing and Alloying on Activity and Stability

Abstract The influence of the noble metal nanoparticle structure on the activity and stability of bimetallic PtPd/Al2O3 catalysts was systematically investigated. Various conventional and advanced synthesis methods were used to tune the initial Pt–Pd mixing/alloying extent. By us...

Solvent-Free Synthesis of Highly Luminescent Solid-State Boric Acid-Assisted Carbon Dots for Stable and High-Contrast Latent Fingerprint Visualization

Abstract The development of efficient, stable, and environmentally friendly fluorescent materials for latent fingerprint visualization remains a major challenge in forensic science. Carbon dots (CDs) have emerged as promising fluorescent nanomaterials owing to their low toxicity,...

A Two-Step Synthesis of Covalent Genetically Encoded Libraries of Peptide-Derived Macrocycles Enables the Use of Electrophiles with Diverse Reactivity

Abstract Genetically encoded libraries of peptide-derived macrocycles containing electrophile “warheads” (cGELs) can be used to identify potent and selective covalent ligands for protein targets. Such cGELs are synthesized either by incorporation of unnatural amino acids that dis...

A Bionic Peristaltic Process for Enhanced Powder Dispersion in Energetic High-Solid-Loading Slurries

Abstract This study introduces a paddle-less bionic peristaltic mixing process, inspired by intestinal biomechanics, for enhanced powder dispersion in energetic high-solid-loading slurries (80% solids). Periodic elastic conduit compression induces low-shear vortices, substantiall...

The Role of Fluoroethylene Carbonate as an Electrolyte Additive on the Chemomechanical Stabilities of NaCrO2 Cathodes in Na-Ion Batteries

Abstract Sodium-ion batteries are promising energy storage devices beyond Li-ion batteries; however, their cycling stability is limited by chemomechanical instabilities in transition-metal oxide cathodes. Although electrolyte additives and other surface modification strategies ha...

Defocus-Insensitive Microscopy via Spatial Phase Modulation Using End-to-End Learning

Abstract In optical microscopy, high spatial resolution comes at the cost of a short depth of field. This trade-off prevents the formation of sharp images of three-dimensional objects or objects moving in and out of focus. Moreover, it is often difficult to know the extent to whi...

Multimodal morphological characterization of the femoro-tibial joint of the black vine weevil ( Otiorhynchus sulcatus )

Abstract As open systems, arthropod joints and mechanical articulations face common challenges such as contamination and loss of lubricant. Recent studies suggest that insects manage these objectives of such open joints using a combination of cuticular microstructures and lubrica...
