Penn State-led research team creates the first ultrathin, compact metalens telescope capable of imaging far-away objects

Astronomers and amateurs alike know the bigger the telescope, the more powerful the imaging capability. To keep the power but streamline one of the bulkier components, a Penn State-led research team created the first ultrathin, compact metalens telescope capable of imaging far-away objects, including the moon. 

Alliance works to keep America prepared for nuclear incidents

It was an unusual scene on an overcast day in July 2022 at the University Park West Campus intramural fields. Near quiet tennis courts, a group of around 100 first-year college students, high school students, graduate students from several universities, faculty and administrators, and military visitors gathered around several display tables, including one dishing out Berkey Creamery ice cream. Nearby, a somewhat ominous, mysterious large black drone hovered with a distinct high-pitched buzz. 

Two-dimensional oxides open door for high-speed electronics

Student works on 2D material in lab

By Matthew Carroll

UNIVERSITY PARK, Pa. – Advances in computing power over the decades have come thanks in part to our ability to make smaller and smaller transistors, a building block of electronic devices, but we are nearing the limit of the silicon materials typically used. A new technique for creating 2D oxide materials may pave the way for future high-speed electronics, according to an international team of scientists.
