It’s beautiful. The brilliant colors of 2,000-year-old Roman glass fragments that were exposed to constant changes in temperature, moisture, and surrounding minerals, are now moving past use in jewelry as pendants or earrings and museum…

Researchers at Duke University and Purdue University managed the arrangement of multiple inorganic and organic layers in crystals with a novel technique, controlling energy levels of electrons and holes within perovskites. The tuning…

Public toilets are often not pleasant places to go, but our bathrooms at home are dirtier than you think. A team of Colorado University engineers ran an experiment during a free week; it wasn't a waste of time. Using two lasers, one…

NIMS and Osaka University researchers succeeded in fabricating a nickel single crystal with only a very few crystalline defects, irradiating nickel powder with a large-radius, flat-top laser beam. The technique may be useful in fabricating…

Did you watch those superhero cartoons as a kid? The ones where the supervillain had a crazy plan to destroy the world every week and at least half of them used a giant mirror to reflect a powerful ray gun? (Doctor Horrible anyone...) Well,…

Paul Scherrer Institute (PSI) researchers have proposed a detailed plan of how faster and better-defined quantum bits—qubits—can be created. The researchers demonstrated how the qubits can be activated, entangled, used as memory bits,…

From helping in the search for life on exoplanets to triggering chemical reactions, diamond anvil cells have been called “scientific workhorses.” Whether helping scientists recreate extreme phenomena or enabling chemical reactions that…

Over the past 15 years, researchers at Ultimate Holography in France have been working to build a hologram printer that possessed all the positive characteristics of a hologram printer but without the drawbacks like expensive lasers, slow…

Laser sources whose spectrum consists of a series of discrete, equally spaced frequency lines that can be used for precise measurements, optical frequency combs have become a major tool for applications such as precise distance measurement,…

Engineers have tried to create imaging technology using terahertz radiation for some time, only to be stymied by what they call the “terahertz gap.” Terahertz radiation is useful to penetrate substances such as fabrics and plastics, and to…
