Researchers print channel structures in quartz glass

Quartz glass is the preferred material for applications that require long-term use because of its high chemical and mechanical stability and excellent optical properties. The engineer Prof. Dr. Bastian E. Rapp from the Department ...

How we know that ancient African people valued fossils and rocks

It's been nearly 50 years since geologist and author Dorothy Vitaliano coined the term "geomythology". This refers to the study of oral traditions from around the world that explain geological and other natural phenomena ...

Recycling quartz from mining waste

An EPFL engineer has discovered a way to extract value from mining waste by recycling the quartz it contains to make composite surfaces for kitchen and bathroom countertops. Brazil-based Vale, the world's largest producer ...

Processing glass like a polymer

Pure quartz glass is highly transparent and resistant to thermal, physical, and chemical impacts. These are optimum prerequisites for use in optics, data technology or medical engineering. For efficient, high-quality machining, ...

Pinpointing the sources of trans-Pacific dust

Airborne dust from Asia travels across the Pacific passport-free, carrying pollution, building soil, and coloring sunsets thousands of miles from its source. Identifying that source is important for understanding atmospheric ...

Physicists unveil new form of matter—time crystals

Normal crystals, likes diamond, are an atomic lattice that repeats in space, but physicists recently suggested making materials that repeat in time. Last year, UC Berkeley's Norman Yao sketched out the phases surrounding ...
