#lubricants

Other things that deserve a Christmas present as much as your car:

Your garbage can lid

Your living room carpet

That spot on your shoulder the doctor swears isn’t cancer

The Ice-Capades

Bowel movements

Circus Peanuts

That doll’s head in a coffee can your father buried in back of the boathouse that he made you swear never to tell anybody about

Used X-Acto blades

Slippery ions create a smoother path to blue energy

Osmotic energy, often called blue energy, is a promising way to generate sustainable electricity from the natural mixing of salt and fresh water. It exploits the voltage that arises when ions from saltwater pass through an ion-selective membrane toward water with a lower salt concentration. However, membranes that let ions flow quickly are usually less selective, and challenges such as maintaining charge separation and mechanical robustness have kept most osmotic energy systems at the experimental stage. Researchers in the Laboratory for Nanoscale Biology (LBEN), led by Aleksandra Radenovic in EPFL's School of Engineering, and in the Interdisciplinary Center for Electron Microscopy (CIME) have published a paper in Nature Energy that demonstrates how these challenges can be overcome.

Physicists achieve near-zero friction on macroscopic scales

For the first time, physicists in China have virtually eliminated the friction felt between two surfaces at scales visible to the naked eye. In demonstrating "structural superlubricity," the team, led by Quanshui Zheng at Tsinghua University, have resolved a long-standing debate surrounding the possibility of the effect. Published in Physical Review Letters, the result could potentially lead to promising new advances in engineering. What structural superlubricity promises When two objects slide over each other, any roughness on their surfaces will almost inevitably resist the motion, creating the force of friction. Yet in 2004, physicists showed that friction can be virtually eliminated between two graphite surfaces, simply by rotating their respective molecular structures.
