Chemical Recycling to Monomer of Commercial Polymers Using Photothermal Conversion
Another strategy for polymer degradation being employed in the Stache lab is photothermal conversion mediated chemical recycling to monomer, wherein we leverage the photothermal effect exhibited by certain materials to generate intense heat gradients for at the surface of the excited agent. This heat, provided it is above the degradation and ceiling temperatures (Td and…

Chemical Upcycling of Commercial Polymers via Photooxidative Degradation
Plastics are useful and ubiquitous in our society. However, they also raise environmental problems due to their persistence in nature. Thus, sustainable approaches to the valorization of plastic waste remain of utmost importance. In the Stache lab, we are developing mild photooxidative degradation methods to upcycle post-consumer plastic waste into commercially important chemical feedstocks. In…

Photothermally Promoted High Activation Energy Barrier Reactions
The photothermal effect, in short, is a photon-promoted reactivity pathway unique to certain nanomaterials wherein, upon irradiation and excitation, the energy acquired is given off in a non-radiative pathway which generates extreme heat gradients. A staple in the biomedical and inorganic materials fields, the photothermal effect has seen little use within the field of organic…
