Laser treatment found to boost battery performance

As the world transitions to renewable power sources such as solar and wind, there is a growing need for high-performance rechargeable batteries to store the energy generated by this intermittent energy source. Today's lithium-ion ...

Why does matter exist? Roundness of electrons may hold clues

In the first moments of our universe, countless numbers of protons, neutrons and electrons formed alongside their antimatter counterparts. As the universe expanded and cooled, almost all these matter and antimatter particles ...

Damping waves with 50,000 rubber grass blades

Dimitris Dermentzoglou, PhD student in Coastal Engineering, is investigating whether salt marshes can serve as a natural solution for coastal protection. It is why he mimics salt marsh vegetation at the TU Delft Waterlab. ...

High-power, high-energy, all-fiber Mamyshev oscillator

High power/energy ultrafast fiber lasers have broadband applications in material processing, medicine, advanced manufacturing and other fields. Compared with solid-state lasers, fiber lasers have the advantages of compact ...

Forming and sensing optical emitters in real time

Seeking new techniques to enable quantum networking, Harvard University researchers have developed a novel laser-based strategy for creating single-atom, near-surface material defects, which can be used to form qubits, the ...

Laser light hybrids control giant currents at ultrafast times

The flow of matter, from macroscopic water currents to the microscopic flow of electric charge, underpins much of the infrastructure of modern times. In the search for breakthroughs in energy efficiency, data storage capacity, ...

Hot electron electrochemistry with ultrafast laser pulses

Laser-induced electrochemical deposition of metals on metals relies possibly on thermal and defect generation effects. When semiconductor substrates are chosen, locally photogenerated electrons can reduce metal ions resulting ...
