upconversion of direct diode semiconductor lasers via thulium- or praseodymium-doped fibers at 480 nm [4] metal vapor, ionized gas lasers of helium-cadmium at 442 nm and 10–200 mW [5] argon-ion lasers at 458 and 488 nm [5] Lasers emitting wavelengths below 445 nm appear violet, but are nonetheless also called blue lasers.
The first production car with carbon-fiber monocoque design was the MCA Centenaire. Now many modern sports cars have carbon-fiber monocoque cells, and some big car manufacturers have also started applying the same in passenger cars like the BMW i3. [1] the Xworks automotive X1 concept was also made in 2004, with a vacuum formed Carbon fibre ...

It is a type of photolithography that uses 13.5 nm extreme ultraviolet (EUV) light from a laser-pulsed tin (Sn) plasma to create intricate patterns on semiconductor substrates. As of 2023, ASML Holding is the only company that produces and sells EUV systems for chip production, targeting 5 nanometer (nm) and 3 nm process nodes.
By definition, visible light is the part of the EM spectrum the human eye is the most sensitive to. Visible light (and near-infrared light) is typically absorbed and emitted by electrons in molecules and atoms that move from one energy level to another. This action allows the chemical mechanisms that underlie human vision and plant photosynthesis.
A single-walled carbon nanotubes (SWCNT) can be envisioned as strip of a graphene molecule (a single sheet of graphite) rolled and joined into a seamless cylinder.The structure of the nanotube can be characterized by the width of this hypothetical strip (that is, the circumference c or diameter d of the tube) and the angle α of the strip relative to the main symmetry axes of the hexagonal ...
Controversially, in 2006, cricket bats with a thin carbon-fiber layer on the back were introduced and used in competitive matches by high-profile players including Ricky Ponting and Michael Hussey. The carbon fiber was claimed to merely increase the durability of the bats, but it was banned from all first-class matches by the ICC in 2007. [37]
As carbon is readily available at low cost, CNFs are popular additives to composite materials. [4] CNFs are very small, existing at the nanometer scale. An atom is between .1-.5 nm, thus specialized microscopic techniques such as Scanning Tunneling Microscopy and Atomic Force Microscopy are required to examine the properties of CNFs. [citation ...
