Functionalization of 2D Materials with Photosensitive Molecules: From Light‐Responsive Hybrid Systems to Multifunctional Devices

“…Indeed, the fabrication of novel 2D material‐based devices bearing unusual functionalities is considered an attractive area in current material science‐oriented research. 2D materials can be functionalized with light‐responsive, magnetoresponsive, and electrochemically switchable moieties, to take advantage of the properties of the different building blocks in order to obtain superior hybrid devices via synergic effects of the components, with the ultimate goal of fabricating hybrid and multifunctional devices which exhibit new and/or enhanced properties and performances. It is worth mentioning that the functionalization strategies can take place by means of both solution‐based and vapor‐based approaches, although the former represents the overwhelming majority of works reported in literature because of a major versatility.…”

A green extraction material — natural cotton fiber for in‐tube solid‐phase microextraction

“…Since its introduction in 1990s, SPME has been developed and applied in many fields, such as environmental monitoring, food analysis, biochemical detection and so on . Various materials have been researched for improving the extraction performance of SPME, like carbon‐based adsorbents (carbon nanotube, graphene) , metal‐organic materials (metal‐organic nanotubes, metal‐organic frameworks) , metal‐based materials (metal nanoparticles, metallic oxide nanorods or nanotubes, bimetallic oxide nanosheets) , organic materials (ionic liquids, polymers, covalent organic frameworks, organic aerogels) , and other materials (silica aerogels, mesoporous materials) . Although these materials exhibited good extraction efficiency, complicated synthesized reaction or chemical functionalization were inevitable.…”
