Why is ice so slippery?

The answer lies in a film of water that is generated by friction, one that is far thinner than expected and much more viscous than usual water through its resemblance to the ‘snow cones’ of crushed ice we drink during the summer.

Researchers reveal charge storage mechanisms of single-layer graphene in ionic liquid

Scientists found that a positively charged ion-species desorption and an ion re-organization dominate the double layer charging during positive and negative polarizations, respectively, leading to the increase in electrical double-layer capacitance with applied potential.

Light-based ‘tractor beam’ assembles materials at the nanoscale

Researchers have developed a method that could make reproducible manufacturing at the nanoscale possible. The team adapted a light-based technology employed widely in biology – known as optical traps or optical tweezers – to operate in a water-free liquid environment of carbon-rich organic solvents, thereby enabling new potential applications.

3D printing batteries – an overview

As an advanced fabrication technique, 3D printing has been increasingly utilized to fabricate complex 3D objects via digitally controlled deposition of phase change and reactive materials and solvent-based inks. When it comes to batteries, 3D printing has several significant advantages compared with conventional battery fabrication technologies and it opens new avenues for the rapid fabrication of 3D-structured batteries with complex architectures and high performance. In next generation futuristic 3D printed energy architectures batteries and supercapacitors could be printed in virtually any shape.

‘Hot’ electrons in metallic nanostructures – non-thermal carriers or heating?

These two pictures, heating vs ‘hot electrons’, are typically presented as orthogonal, and theories either treat one or the other. In a recent work, these two pictures were merged into a single theoretical framework, which enabled them to fully evaluate both the electron distribution and the electron and lattice temperatures of an illuminated nanoparticle.

Nanoparticle drug delivery provides pain relief and more effective opioid alternative in animal study

An international team of researchers has used nanoparticles to deliver a drug – one that previously failed in clinical trials for pain – into specific compartments of nerve cells, dramatically increasing its ability to treat pain in mice and rats.
