Imaging the chemical structure of individual molecules, atom by atom

Using atomic force microscopy images, scientists developed a guide for discriminating atoms other than hydrogen and carbon in aromatic molecules.

Nanoquakes and molecular sponges for weighing and separating tiny masses

Chemists and physicists report how they have succeeded in the extremely difficult separation of hydrogen and deuterium in a gas mixture.

The role of metal cations in perovskite solar cells

Scientists explore the metal cations for perovskite solar cells by focusing on the position of the cations in perovskites, the modulation of the film quality, and the influence on the photovoltaic performance.

New nanoantennas to improve ultra-fast wireless connections

Researchers experimentally proved the first wireless dielectric-plasmonic connection thanks to a new type of dielectric nanoantenna that overcomes the limitations that plasmonics had until now, opening the door to new hybrid configurations.

Bridging the nanoscale gap: A deep look inside atomic switches

Researchers have gained unprecedented insight into the inner workings of an atomic switch. By investigating the composition of the tiny metal 'bridge' that forms inside the switch, their findings may spur the design of atomic switches with improved performance.

Atomically precise models improve understanding of fuel cells

Computer simulations using models based on real-world atomic structures from microscope observations shed new light on the reaction pathways in fuel cells.

Better thermal conductivity by adjusting the arrangement of atoms

Scientists have shown that the atomic vibrations that determine heat generation in nanowires can be controlled through the arrangement of atoms alone.
