Observing Silver Nanoparticles in Real Time

Caleb Sooknanan ‘20 Silver nanoparticle systems are commonly used in medical treatments, food, and sports products for their antibacterial and anti-inflammatory properties; however, more research is needed to understand how such nanoparticles react in biological systems. Doctor Kristina Tschulik and researchers from Ruhr-University Bochum in Germany used a novel combination of electrochemical and spectroscopic methods to observe silver nanoparticle behavior in real time. With these … Continue reading Observing Silver Nanoparticles in Real Time

Using Microelectrode Arrays on Soft Substances

Caleb Sooknanan ‘20 Microelectrode arrays or MEAs are electrode systems that can be used to analyze electric signals among cardiac cells and neuronal cells, repair sensory abilities among human patients, and address nervous system disorders. However, most of the devices currently associated with MEAs rely on silicon or polymer substances, which make it difficult for scientists to mimic the structural and functional capabilities of living … Continue reading Using Microelectrode Arrays on Soft Substances

Energy, Spin, and Charge All in One

Neomi Lewis ‘21 The field of economics is constantly making strides to better manipulate and strategically implement properties of charged particles. Charged particles play instrumental roles in devising electronic devices. Most particles that are commonly used, however, only retain one property that can be manipulated. Researchers from Duke University now have reason to believe that “trions,” a quasiparticle, can also be controlled in useful ways. … Continue reading Energy, Spin, and Charge All in One
