Diffusive Memristor as a Synapse
Neuromorphic computing, systems designed to mimic the biological nervous system, require far less power than current computer processors. The increased efficiency makes feasible artificial intelligence applications for smaller, hand-held devices (e.g. smartphones, tablets).  To this end, UMass inventors have designed hardware components that mimic neuronal synapses (Figure A). Specifically, diffusive Ag-in-oxide memristors show a temporal response during and after stimulation similar to that of a biological synapse. The novel diffusive memristor and its synapse-like dynamics enable a direct emulation of both short- and long-term plasticity of biological synapses and represent a major advancement in a hardware implementation for neuromorphic computing.

Fulleropyrrolidine Interlayers for High Efficiency Perovskite Solar Cells
Interface engineering is critical for achieving efficient solar cells.  This invention provides a significant power conversion efficiency (PCE) improvement of fullerene/perovskite planar heterojunction solar cells from 7.50% to 15.48% by inserting a fulleropyrrolidine interlayer between the metal electrode and the electron transport layer. The interlayer enhances recombination resistance, increases electron extraction rate and prolongs free carrier lifetime.cells.
