Modern flashlights with bright, white LEDs probably use a mixed indium-gallium nitride alloy as semiconductor to convert electricity into light. A Blu-ray disk system also employs a blue InGaN-based laser. However, indium is becoming scarce and costly, sending researchers scurrying to find an alternative technology.
Ohio State University researchers recently discovered potential keys to mass producing a specific pattern of graphite in a layer just one atom thick, signaling a breakthrough that could lead to “graphene” challenging silicon as the preferred material for manufacturing faster, more efficient computer chips.
Two Ohio State University astronomy researchers have established an international reputation for using X-rays and supercomputers to search the vast depths of space to identify elusive black holes. Now, they and their interdisciplinary colleagues are repositioning their scientific methodology to peer into the human body to enhance cancer therapy and diagnostics (theranostics).
Alzheimer’s disease is the most common human neurodegenerative disorder, affecting as many as 5.1 million people in America alone. Alzheimer’s leads to progressive and irreversible memory loss, disability and, eventually, death through a complex series of events that take place in the brain over a period of many years.
