The Economics of Interchange Fees and Their Regulation: An Overview [PDF]
This essay surveys the economic literature on interchange fees and the debate over whether interchange should be regulated and, if so, how. We consider, first, the operation of unitary payment systems, like American Express, in the context of the recent ...

Advanced Science, EarlyView.Polymer‐based hydrogels have emerged as promising materials for atmospheric water harvesting (AWH) due to their high water affinity, tunable network structure, and excellent moisture adsorption‐desorption performance. Functional hydrogel systems enable efficient water capture and controlled release under low‐energy conditions, offering a sustainable ...

Advanced Science, EarlyView.A lattice‐strain‐engineered Co0.28Cu0.67Ir0.05 trimetallic alloy nanoparticle electrocatalyst is rationally designed for efficient alkaline seawater electrolysis. Larger Ir atoms in the CoCu lattice modulate the local coordination environment, generating compressive lattice strain and highly active catalytic sites.

Advanced Science, EarlyView.Simultaneous two‐mode Raman thermometry reveals strong in‐plane anisotropic thermal conductivity and thermal expansion coefficients in low‐symmetry few‐layer ReS2. By decoupling thermal transport along the crystallographic a‐ and b‐axes within a single optical configuration, this study provides robust experimental evidence and ab initio theoretical ...

Advanced Science, EarlyView.A novel B2‐ordered Ti‐Zr‐V‐Al medium‐entropy intermetallic is developed through controlled metastability engineering, which activates an ordered TRIP effect via a new B2→D019‐α2 transformation with a distinctive {0001}α2//{110}B2, <11‐20>α2//<100>B2 orientation relationship. This alloy achieves an elongation of ∼7%, a strength of ∼1.1 GPa, and superior

Advanced Science, EarlyView.We present a versatile DNA‐encoded library (DEL) platform designed for rapid library synthesis and subsequent screening for chemical inducers of proximity (CIPs) across various presenter proteins of choice. Applying this approach, we discovered a novel molecular glue‐like compound mediating CRBN‐BRD9 ternary complex formation with remarkable ...

Nascent Extracellular Matrix Converts Biomaterial Cues into Cell Fate Decisions
Advanced 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.
