Viscosity is one of the most fundamental physical properties of a liquid. Yet, its atomic and molecular origins are not well understood. Recently,
The lithium-sulfur battery has a theoretical energy density much greater than commercial lithium-ion batteries; however, the technology exhibits
The remarkable mobility of lithium ions in solids has been a key factor in the development of commercial lithium-ion batteries. A generally
Batteries based on magnesium metal as the negative electrode (anode) promise much higher energy density compared to lithium-ion systems and are, at
Mechanical gradients are often employed in nature to prevent damage from large forces by creating a smooth transition from strong to weak
Light could induce desirable structural changes in thin sheets of materials. These materials could have applications ranging from data storage
The atomically thin nature of layered 2-D semiconductors gives rise to a gamut of unique physical properties, which often do not exist in
Low-cost, large-area scalability by solution processing is an important advantage of organic polymer solar cells. Typical organic solar cells,
To capture the fast motions of electrons that govern many chemical processes, x-ray pulses in the attosecond range are required. Two methods have
Using the high brightness, short-pulse X-ray free-electron laser at the SLAC National Accelerator Laboratory, the team measured the speed at which
