Switchable and Memorable Adhesion of Gold-Coated Microspheres with Electrochemical Modulation

Description: Switchable adhesives using stimuli-responsive systems have many applications, including transfer printing, climbing robots, and gripping in pick and place processes. Among these adhesives, electroadhesive surface can spontaneously adjust their adhesion in response to an external electric field. However, electroadhesives usually need high voltage (e.g. kV) and the adhesion disappears upon turning off the signal. These limitations make them complicated and costly. In this research, we demonstrateā€¦ more

Attachment to God: Pathways to Resilience and Posttraumatic Growth

Description: Having a secure attachment to God may act as a buffer against stress. Secure attachment to God has been positively associated with adaptive outcomes following stress, such as higher levels of stress-related growth and fewer maladaptive symptoms including depression, prolonged grief, and traumatic distress. However, relatively few studies have empirically tested the relationship between attachment to God and resilience and posttraumatic growth. Thus, the current study explored the potential assoā€¦ more

Restore, Reform, React, Revolt: Leopold II and the Risorgimento in the Grand Duchy of Tuscany, 1814-1859

Description: The Risorgimento or "resurrection" of Italy united a collection of independent Italian kingdoms, duchies, and principalities under the auspices of the Piedmontese House of Savoy. No longer was Italy a mere expression gĆ©ographique, as Austrian Chancellor Klemens von Metternich snidely remarked in 1847, but a united nation state. Studies of the Risorgimento successfully highlight the role of famous Piedmontese and Italian nationalists in demonstrating the success of the movement. However, the smaā€¦ more
