An Assisting Contact Electrification Strategy for Achieving Self-Recoverable Mechanoluminescence. [PDF]
Adv Sci (Weinh)ABSTRACT Self‐recoverable mechanoluminescence (ML) is a unique property of materials that can stably emit light under repeated stress, enabling new applications in smart sensing, displays, and wearable devices. However, self‐recoverable ML is very rare and only observed in a few active phosphors excited by piezoelectricity or contact electrification ...

Drop-Location-Insensitive Droplet-Based Electricity Generator Using Polydimethylsiloxane Slippery Covalently Attached Liquid Coatings. [PDF]
Adv Sci (Weinh)Drop‐location sensitivity remains a key barrier to practical droplet‐based electricity generators (DEGs). Here, a polydimethylsiloxane slippery covalently attached liquid (PDMS‐SCAL)‐coated interface promotes droplet sliding instead of splitting or bouncing, allowing stable electricity generation from randomly falling raindrops. The resulting PDMS‐SCAL‐
