When you hear the words Alzheimer's disease, what do you think of? The truth is, the picture most of us have of the disease is incomplete. Alzheimer's disease doesn't start when someone starts to lose their memory. It actually starts years – sometimes decades – earlier. The Rethinking Alzheimer's Disease Podcast is an engaging, narrative-style podcast miniseries for those curious or motivated to learn about Alzheimer’s disease. Perhaps you have a family member with Alzheimer’s disease, or ca ...

In this podcast episode, MRS Bulletin’s Sophia Chen interviews Victor Lopez-Richard from Federal University of São Carlos in Brazil about his memory device called a mem-emitter. Unlike a memresistor (short for “memory resistor”), which made of materials whose electrical resistance can be tuned, the mem-emitter is used to tune optical properties. Experimentally, Lopez-Richard’s research group made the device out of molybdenum diselenide, which is a transition metal dichalcogenide, that was then layered onto a dielectric known as a clinochlore. The researchers found that they were able to tune the intensity of the light emitted according to theoretical predictions. This work was published in a recent issue of Nano Letters.
