Is Acne the Same Around the World?

Acne is a common skin disease associated with a range of sequelae. These include scarring and dyspigmentation, emotional and psychosocial disturbances, and occupational problems, in part because acne often manifests on the face, in addition to other body areas, and is highly visible. Worldwide, the prevalence of acne is estimated at 9.

Volatile and Nonvolatile Programmable Iontronic Memristor with Lithium Imbued TiO for Neuromorphic Computing Applications.

We demonstrate a lithium (Li) imbued TiO iontronic device that exhibits synapse-like short-term plasticity behavior without requiring a forming process beforehand or a compliance current during switching. A solid-state electrolyte lithium phosphorus oxynitride (LiPON) behaves as the ion source, and the embedding and releasing of Li ions inside the cathodic like TiO renders volatile conductance responses from the device and offers a natural platform for hardware simulating neuron functionalities. Besides, these devices possess high uniformity and great endurance as no conductive filaments are present.
