“Capturing, manipulating, and emitting high-frequency waves and lights drives my passion for exploring the fundamental limits of light-matter interactions,” notes Hao, “paving the way for the next generation of photonic, biosensing, and communication technologies.”

Congratulations to our PhD candidate, Hao Zhang, for being awarded the SPIE Optics and Photonics Scholarship.

His work cuts across academic and national lab priorities by focusing on nonlinear optics, advanced pulse shaping for ultra-high-brightness light sources, and photonic transduction.

The study just published below, led by Adi Natan at SLAC and colleagues at Stanford University, Brown , and UCLA, offers a remarkable insight into the real-space and energy distribution observation of one model photodissociative process from a transition metal complex.

Additionally, controlling energy flow at the atomic level can optimize light-driven technologies, such as #photodynamic therapy, photoresponsive materials, and next-generation #optoelectronic devices.

Real-space observation of the dissociation of a transition metal complex and its concurrent energy redistribution - Nature Communications Metal carbonyl complexes show photoreactivity interesting for catalytic and biological applications. Here the authors capture the structural dynamics of the photodissociation of iron pentacarbonyl in ...

Understanding energy redistribution in #photochemical reactions is crucial in enabling the design of more efficient #photocatalysts for sustainable energy applications (e.g., solar fuels, CO₂ reduction) and precision synthesis in #pharmaceuticals.
