At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same ...

First experimental observation of matter-wave diffraction in a short-lived electron-positron atom using a graphene-based diffraction grating. (Nanowerk News) One of the discoveries that fundamentally ...

For pharmaceuticals, knowing the chemical composition is not enough - molecular geometry and crystal structure also play an important role in a drug's activity. By using a method based on electron ...

In 1912, scientists invented X-ray crystallography and revealed a crystal’s atomic structure for the first time Tess Joosse Humans have marveled at crystals for millennia. Viridescent emerald, rich ...

Crystallography is the science of analyzing the pattern produced by shining an X-ray beam through a material sample. A powder sample produces a different pattern than solid crystal. One longstanding ...

Physicists have finally watched positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a tiny billiard ball. In a set of ...

For a crystal-clear view of cutting-edge science, step into Brandon Mercado’s lab in the basement of Kline Chemistry Laboratory. But there’s a new kid in town. CBIC’s Structural Science Facility now ...

Ptychography is an area-by-area scanning method that uses constant, coherent illumination to scan a region of a sample in several adjacent and overlapping locations. The dispersed radiation is ...

One longstanding problem has sidelined life-saving drugs, stalled next-generation batteries, and kept archaeologists from identifying the origins of ancient artifacts. For more than 100 years, ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...
