Sgr A*, at the heart of the Milky Way and clocking in at 4.3 million solar masses, is the closest supermassive black hole we have access to. It's also on the quiescent end of the activity scale, which ...

This work reports the design of an efficient multiband UC system based on Ln3+/Yb3+-doped core-shell upconversion ...

Each wavelength carries inherent energy that ... and achieved a record-breaking quantum yield of 7.3 % in the NIR range (2200 nm) for hydrogen production. Distinctively, unlike conventional ...

However, decreasing the wavelength of light ... for example in that entire range; 400 nm is a violet color and 780 is decidedly red. Last time we looked at NIR, there was coffee brewing.

and superb wavelength repeatability. The NIR-O process analyzer is a suitable tool for various online analyses of a wide range processes and process streams. With the built-in capacity to add more ...
