Researchers enhance durability of low-cost solar cells made from nano-sized crystals
Researchers enhance durability of low-cost solar cells made from nano-sized crystals
An international team of researchers has developed a new technique to enhance the durability of inverted perovskite solar cells - an important step toward commercialization of an emerging photovoltaic technology that could significantly reduce the cost of solar energy. Unlike traditional solar cells, which are made from wafers of extremely high-purity silicon, perovskite solar cells are built from nano-sized crystals.

Chemists create nanomachines by breaking them apart
Chemists create nanomachines by breaking them apart
Some "broken" nanomachines better sense their environment while others gain the ability to control their activity over time, researchers at Université de Montréal find. CONTENU - "Every act of creation," Picasso famously noted, "is first an act of destruction." Taking this concept literally, researchers in Canada have now discovered that "breaking" molecular nanomachines basic to life can create new ones that work even better.

New discovery may be key to controlling chemical reactions
Unexpected resonance frequencies observed in reactions between two molecules A new study published today in Nature is changing our understanding of chemical reactions and overturning previous theoretical models by finding an unexpected resonance frequency during the reaction of two molecules. Resonance is when one object vibrating at the same natural frequency as a second object forces that second object into vibrational motion.

Experimental physicists take step toward understanding natural quantum systems
Experimental physicists take step toward understanding natural quantum systems
"Suppose you knew everything there was to know about a water molecule - the chemical formula, the bond angle, etc.," says experimental physicist  Joseph Thywissen . "You might know everything about the molecule, but still not know there are waves on the ocean - much less how to surf them," he says.

A process to produce fuel from banana peel
A process to produce fuel from banana peel
This green process could be used to valorize other food remains rich in cellulose or lignin The banana is an excellent source of energy, nutritionists will tell you unanimously. So is the peel, according to Marie-Josée Dumont, but in the fuel sense of the term. The professor from the Department of Chemical Engineering at Laval University and her colleagues at McGill University have just taken a new step towards a fuel based on banana peel by substantially improving the efficiency of an existing chemical process.
