Atom-by-atom: Imaging structural transformations in 2D materials

Silicon-based electronics are approaching their physical limitations and new materials are needed to keep up with current technological demands. Two-dimensional (2D) materials have a rich array of properties, including superconductivity ...

Discovery overturns major assumptions in crystal photochemistry

Stimuli-responsive materials, whose physical properties change in response to external stimuli such as light and heat, are being widely studied as next-generation functional materials. Photo-responsive materials in particular ...

Combining magnetism and light to fight cancer

By combining, in a liposome, magnetic nanoparticles and photosensitizers that are simultaneously and remotely activated by external physical stimuli (a magnetic field and light), scientists at the Laboratoire Matière et ...

Unraveling bacterial behavior

Bacteria encounter a constant barrage of ever-changing temperature, acidity and chemical stimuli from their environment. The cells must absorb all of this information and choose the correct response—whether boosting their ...

Human hearing beats the Fourier uncertainty principle

(Phys.org)—For the first time, physicists have found that humans can discriminate a sound's frequency (related to a note's pitch) and timing (whether a note comes before or after another note) more than 10 times better ...
