Taking magnetism for a spin: exploring the mysteries of skyrmions

Scientists have discovered the relaxation dynamics of a zero-field state in skyrmions, a spinning magnetic phenomenon that has potential applications in data storage and spintronic devices.

New water splitting catalyst could make it easier to generate solar fuel

Water splitting, the process of harvesting solar energy to generate energy-dense fuels, could be simplified thanks to new research.

New 3-D nanoprinting strategy opens door to revolution in medicine, robotics

Engineers demonstrate their approach by printing the smallest-known 3D microfluidic circuit element.

Researchers find the trick to molding metal at the nanoscale

Researchers have developed a process that allows manufacturers to essentially shape any metal and alloy and replicate even the smallest details.

Multitasking graphene ink printed into tiny flexible supercapacitors

Researchers have developed an easy way to make complicated arrays of microsupercapacitors that involves screen-printing them out of graphene ink. The simplicity and freedom offered by the approach will aid the development of new approaches to electronics and flexible devices.

Current generation via quantum proton transfer

Researchers have discovered that proton transfer in electrochemical reactions is governed by the quantum tunneling effect under the specific conditions. In addition, they made a first ever observation of the transition between the quantum and classical regimes in electrochemical proton transfer by controlling potential.

Collision of individual atoms leads to twofold change of angular momentum

Scientists have investigated the consequences of the collision of two atoms in a weak magnetic field at low temperature. For the first time they have discovered that atoms, carrying their angular momentum in individual packets (quanta), thereby exchange two packets.
