VSEPR theory provides a practical way to predict the 3D shapes of molecules by focusing on how electron pairs repel each other. This model explains why atoms arrange in specific geometries, from ...

A comet from another star system is carrying water unlike anything astronomers have seen before. The interstellar visitor ...

Researchers at Ulm University and Friedrich-Schiller-Universität Jena have built a molecular system that captures solar energy in a water-soluble redox copolymer, stores it at more than 80% charging ...

Chemists have discovered a new molecular shape, and it is twice as odd as the twisty Möbius strip. The Möbius strip is a looped band with a twist, such that something tiny, such as an ant, would have ...

Repsol has approved its second 100 MW electrolyzer at the Petronor industrial complex in Bilbao. “The electrolyzer will have the capacity to produce up to 15,000 tons of renewable hydrogen annually, ...

A man grabbed a bottle of what looked like water and took a swig. Hours later, he was in the emergency department with a life-threatening cerebral air gas embolism. The problem: It was highly ...

Organic liquid hydrogen storage technology enables safe, efficient, and reversible hydrogen storage and transportation at ambient temperature and pressure, and is highly compatible with existing ...

Scientists have developed molecular devices that can switch roles, behaving as memory, logic, or learning elements within the same structure. The breakthrough comes from precise chemical design that ...

For more than 50 years, scientists have sought alternatives to silicon for building molecular electronics. The vision was elegant; the reality proved far more complex. Within a device, molecules ...

Sunlight, water, and air may soon replace fossil-fuel-driven chemistry in producing hydrogen peroxide, one of the world’s most essential industrial molecules. Cornell researchers have unveiled a solar ...
