New devices boast a photovoltaic efficiency of 20.2% and an open-circuit voltage of 1.13 V
New material transports excitons over length scales comparable to the optical absorption depth
The devices also boast short channel lengths, high channel conductance and excellent switching characteristics
The material repairs itself in a process that is somewhat analogous to plasticity in nervous tissue
Printing liquid structures in a granular support material offers new route to producing biomaterials
Injectable angiogenic material might be used in a potential new therapy for stroke
Researchers have used a photolithographic-stereolithographic-tandem process to make biomimetic structures that help stem cells grow
Fractalized device could be used in biosensing
A new safe and non-invasive technique could be an alternative to refractive surgery
Reducing the interactions between electrons and phonons in these layered materials makes them emit brighter light
