Scientists at Berkeley Lab and UC Berkeley have found a simple new way to produce nanoscale wires that can serve as bright, stable and tunable lasers—an advance toward using light to transmit data.
Understanding and manipulating plasmons is important for their potential use in photovoltaics, solar cell water splitting, and sunlight-induced fuel production from CO2. Berkeley Lab researchers have used a real-time numerical algorithm to study both the plasmon and hot carrier within the same framework. That is critical for understanding how long a particle stays excited, and whether there is energy backflow from hot carrier to plasmon.
Berkeley Lab researchers have demonstrated that diamonds may hold the key to the future for nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) technologies. NMR/MRI signals were significantly strengthened through the hyperpolarization of carbon-13 nuclei in diamond using microwaves.
