Control of Covalent Bond Enables Efficient Magnetic Cooling
Advanced Materials, EarlyView.Giant and reversible magnetocaloric effect (MCE) is achieved by tuning covalency through sub‐unit‐cell chemical engineering, establishing a novel design principle for effective hysteresis control in magnetocaloric materials. Abstract Magnetic cooling, harnessing the temperature change in matter when exposed to a magnetic field, presents an energy ...

Entrepreneurship in International Trade [PDF]
Motivated by evidence on the importance of incomplete information and networks in international trade, we investigate the supply of 'network intermediation.' We hypothesize that the agents who become international trade intermediaries first accumulate ...

Advanced Porous Materials for Maritime Carbon Capture
Advanced Materials, EarlyView.Carbon capture from emission sources, such as marine vessels, has attracted significant attention over the years. To achieve this goal, sorbents such as metal–organic frameworks (MOFs), porous polymer networks (PPNs), covalent organic frameworks (COFs), and their post‐synthetic modifications are currently being explored.
