Applied physicist Watt W. Webb, the S.B. Eckert Professor of Engineering Emeritus and a pioneer in methods for imaging living biological systems, died Oct. 29 in New York City. He was 93. Webb was best known as the biophysicist who co-invented fluorescence correlation spectroscopy and multiphoton microscopy – imaging techniques that have revolutionized how scientists observe biological dynamics and structures deep within living tissue.

A collaboration between researchers from Cornell, Northwestern University and University of Virgina combined complementary imaging techniques to explore the atomic structure of human enamel, exposing tiny chemical flaws in the fundamental building blocks of our teeth. The findings could help scientists prevent or possibly reverse tooth decay. Read the full Chronicle Article here. Read more

Regarding his team's new mixed-state electron ptychography method, Professor David Muller, Samuel B. Eckert Professor of Engineering, says it entails: “hardware to count every electron and software to make sure every electron counts.” Mixed-state electron ptychography uses complex algorithms to achieve faster, less destructive, more efficient imaging with picometer precision.

Professor Jie Shan and Associate Professor Kin Fai Mak co-author recent paper on a new real-time imaging technique that is fast and sensitive enough to observe elusive critical fluctuations in two-dimensional magnets. This technique allows researchers to control the fluctuations and switch magnetism via a “passive” mechanism that could eventually lead to more energy-efficient magnetic storage devices. The team’s paper, “Imaging and Control of Critical Fluctuations in Two-Dimensional Magnets,” published June 8 in Nature Materials. Learn more in the Cornell Chronicle article here. Read more

Fuchs’s group demonstrates spin resonance can be driven solely by acoustics. eliminates need for the magnetic antenna. The team’s paper, “Acoustically Driving the Single Quantum Spin Transition of Diamond Nitrogen-Vacancy Centers,” published May 27 in Physical Review Applied. Read more

AEP Associate Professor Greg Fuchs among the multifaceted team that recently published “Local Photothermal Control of Phase Transitions for On-Demand Room-Temperature Rewritable Magnetic Patterning” in Advanced Materials. The study demonstrates a technique for writing, erasing and rewriting microscopic magnetic patterns onto a material and has applications for ultrafast computer memory.
