Sapphires show their true colors: Not water-loving

In 1805, Thomas Young studied the mechanical equilibrium at the solid/liquid/gas three-phase contact line (the balance of forces acting on the contact line formed by the intersection of the liquid-gas interface and the solid ...

Researchers develop a new membraneless fuel cell

The research team of INRS Professor Mohamed Mohamedi has designed a green membraneless fuel cell that uses oxygen from the air. The results of this innovative microfluidic application—a first in Canada—were published ...

Understanding oxygen-reducing enzymes

Methane is a powerful greenhouse gas that plays a central role in the global carbon cycle. At the same time, it is an important energy source for us humans. About half of its annual production is made by microorganisms known ...

Nanomaterials based strategies for treatment of hypoxic tumor

Hypoxia is a typical characteristic of most tumors, owing to the fast consumption of oxygen by tumor tissue over the supply through malformed and abnormal tumor vasculature. Hypoxia in tumor tissue promotes the probability ...

Deprived of oxygen, layers of bacteria get creative

Bacteria are found living nearly everywhere on our planet, from the inside of human intestines to the soil to deep underwater. When scientists study bacteria in the lab, they most often examine individual bacterial cells ...

Unusual electron sharing found in cool crystal

A team of scientists led by Nagoya University in Japan has detected a highly unusual atomic configuration in a tungsten-based material. Until now, the atomic configuration had only been seen in trihydrogen, an ion that exists ...

Water molecules are gold for nanocatalysis

Nanocatalysts made of gold nanoparticles dispersed on metal oxides are very promising for the industrial, selective oxidation of compounds, including alcohols, into valuable chemicals. They show high catalytic activity, particularly ...
