The node label (e.g. "5 nm") no longer represents a physical dimension and hasn't for some time -- it's simply a continuation of a naming convention. In fact, while we used to scale down transistors by simply reducing the gate width (where the naming convention originated) we now take far more elaborate steps to do so.
Yup, such a blatant copycat attempt. All the way down to the angle the photos are taken from. Good thing for Boosted that you can't just copy a well engineered drivetrain.
Actually, Yuneec Technology started our E-GO Cruiser design even before Boosted Boards launched their Kickstarter campaign. Yuneec are experts in Electric Propulsion Systems, be they for light aircraft, ultralights, drones or electric longboards. We design and manufacture everything and our new and substantial office and warehouse in California is creating plenty of US jobs.
The color change of gold and CdSe particles with size are due to two different effects.
CdSe is a semiconductor, and reducing the CdSe nanoparticle size increases its band gap through a process called quantum confinement. For smaller particles, it requires a photon to have higher energy (i.e. smaller wavelength) to be absorbed.
Gold particles derive their color from the scattering mechanism mentioned in the parent comment.
Completely agreed; I was just providing another example for how the colour of large objects does not necessarily have anything to do with the colour of small objects. Thanks for the added context :)
