Silver and titanium nanomaterials present in wastewater may have toxic effects on crustaceans and fish cells

New research shows that silver and titanium nanoparticles in present in treated wastewater may have toxic effects on algae, crustaceans and fish gill cells, and the effects seem to be species dependent.

Scientists discover 'ripple' in flexible material that could improve electronic properties

A newly discovered phenomenon in a flexible 2D semiconductor could affect its promise for electronic devices.

A marvelous molecular machine

A finely-tuned molecular process in the camouflage of certain squid may lead to the next generation of bio-inspired synthetic materials.

Newly developed nanoparticles help fight lung cancer in animal model

Scientists have reported a new approach to treating lung cancer with inhaled nanoparticles.

Chemists map an artificial molecular self-assembly pathway with complexities of life

Chemists have studied how molecular building blocks can either form a spherical cage or an ultrathin sheet that shows some of the basic properties of a 'smart' material that can respond to its environment.

How much does an AFM cost?

The answer to the question how much an atomic force microscope (AFM) costs is always 'it depends'. The pricing of scanning probe microscopes is influenced by many factors, like the performance, capabilities and modes you expect from your instrument, which in turn determine the components and complexity of the technology employed.

Storing energy in hydrogen 20 times more effective using platinum-nickel nanocatalyst

Catalysts accelerate chemical reactions, but the widely used metal platinum is scarce and expensive. Researchers have now developed an alternative with a 20x higher activity: a catalyst with hollow nanocages of an alloy of nickel and platinum.
