Rough and Tough: How Particle Surface Roughness Affects Liquid Marble Formation and Stability

open access: yesAdvanced Science, EarlyView.
This study investigates the influence of particle surface roughness on the formation and stability of liquid marbles using well‐defined colloidal supraparticles as model systems. Increasing surface roughness enhances the interfacial contact angle, improves mechanical stability by increasing deformation resistance upon impact, and enables liquid marble ...

Suppressing Colloidal Quantum Dot Multimer Fusion Leads to High‐Performance InSb Infrared Photodetectors

open access: yesAdvanced Science, EarlyView.
This work shows that the fusion of InSb colloidal quantum dots (CQDs) leads to the formation of band‐tail trap states that are detrimental to the performance of optoelectronic devices. These results highlight the critical role of suppressing band‐tail trap states and passivating surface defects in enhancing device performance and motivate toward the ...
