Perovskite solar cells get an upgrade

Through the strategic use of the element indium to replace some of the lead in perovskites, materials scientists say they're better able to engineer the defects in cesium-lead-iodide solar cells that affect the compound?s band gap, a critical property in solar cell efficiency.

Researchers design 'intelligent' metamaterial to make MRIs affordable and accessible

The new metamaterial could revolutionize magnetic resonance imaging (MRI), making the entire MRI process faster, safer, and more accessible to patients around the world.

Nanoparticle orientation offers a way to enhance drug delivery

Coating particles with 'right-handed' molecules could help them penetrate cancer cells more easily.

Scientists discover breakthrough way to look at the surface of nanoparticles

New method to explore the surface of nanoparticles, unlike existing chemical procedures which have severe limitations.

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.

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.

Ultrafast quantum motion in a nanoscale trap detected

Researchers have reported the detection of a picosecond electron motion in a silicon transistor. This study presents a new protocol for measuring ultrafast electronic dynamics in an effective time-resolved fashion of picosecond resolution.
