We report on an observation of the 1S-2S transition in atomic hydrogen using an ultraviolet mode-locked laser. The 243 nm femtosecond laser is produced through second-harmonic generation and ...

A 2-methoxynaphthalene dimer system is demonstrated as a sequential two photon photoacid generator for double exposure (DE) lithography. DE is based on the use of staggered exposures and is proposed ...

Researchers at the University of British Columbia (UBC) are proposing a blueprint for a ‘universal translator’ in quantum networks... A key hurdle in quantum networking, they report, is a device that ...

University of British Columbia researchers are aiming at long-distance entangled quantum networks with a coherent microwave-to-optical photon converter, that can theoretically be fabricated on a ...

Dr Mak and colleagues compared proton and photon radiotherapy in the phase 2 ACNS1123 trial (NCT01602666), which included 70 patients with NGGCTs. The patients had a mean age of 11.8 years, and 26 ...

A computational analysis of the electron- and photon-driven surface-plasmon resonances of monomer and dimer metal nanorods is presented to elucidate the differences and similarities between the two ...

Gainesville (Ga.) HS offensive lineman Krew Moledor announced Wednesday that he has given his verbal pledge to the Cardinals. He chose Louisville over held offers from Southern Miss, Western ...

Drift club “Balkan Krew” attempted to hold an illegal drift meeting in Geel on Saturday night. Hundreds of vehicles converged at the Geel-East slip road complex, causing traffic congestion. ‘Due to a ...

Some upcoming laser facilities that could have enough power to confirm the photon-photon scattering predicted by the vacuum four-wave mixing theory include the European ‘Extreme Light Infrastructure ...
