New insight into the inevitable oxidation-dissolution behavior of MoS2 at humid environments: Unexpected persistent generation of hydroxyl radicals

Calcium Alginate as an Active Device Component for Light-Triggered Degradation of 2D MoS2-Based Transient Electronics

“…However, in these approaches, challenges exist associated with controlling the degradation rate of device components, particularly in pHdependent oxidative solution-triggering processes. 18,19 Also, the instant disintegration of water-soluble components in aqueous solutions significantly restricts the versatility of transient electronics, which becomes pronounced in situations where precisely controlled transient characteristics are demanded. 20 Furthermore, the functionalities of these solution-degradable substrates in the conventional approaches are limited to introducing the transient characteristics only, without offering any additional values to device performances.…”

“…A number of organic or inorganic semiconducting materials have been explored in various structures, − which have recently expanded to near atom-thickness two-dimensional transition (2D) metal dichalcogenide layers, notably molybdenum disulfide (MoS 2 ), due to their unprecedented optoelectronic and mechanical properties. , Recent advancements in 2D MoS 2 -based transition electronics have focused on fabricating devices on biodegradable substrates such as cellulose or poly­(vinyl alcohol) and demonstrating their disintegration in aqueous or pH-sensitive buffer solutions. However, in these approaches, challenges exist associated with controlling the degradation rate of device components, particularly in pH-dependent oxidative solution-triggering processes. , Also, the instant disintegration of water-soluble components in aqueous solutions significantly restricts the versatility of transient electronics, which becomes pronounced in situations where precisely controlled transient characteristics are demanded .
