On quartz sheets, the angular rhombic boron nitride crystals with a thickness of only 1 to 3 microns are as thin as cicada wings, but their energy efficiency is 100 to 10000 times higher than traditional optical crystals. At the opening ceremony of the 2024 Zhongguancun Forum Annual Conference held on April 25th, the world's thinnest known optical crystal was listed as one of the top ten technolog...
Nikon Vision, a subsidiary of Nikon Corporation, is pleased to announce the launch of the COOLSHOT 20i GIII laser rangefinder for golfers, which is Nikon's small and lightweight model in the COOLSHOT series.While maintaining the lightweight and compact size of the COOLSHOT 20i GII, the new model notifies users through brief vibrations that the distance to the flagpole has been measured.When measur...
Conservation of energy is a fundamental concept in physics that can be used to explain anything from planetary orbits to the internal workings of individual atoms.Energy can be converted into other forms, but the overall energy level is usually considered to vary over time. Therefore, when attempting to describe a system, physicists usually pay attention to ensuring that it is isolated from the su...
Recently, researchers from Osaka University in Japan have developed the world's first compact, wavelength tunable blue semiconductor laser in a new study. This breakthrough paves the way for far ultraviolet light technology and brings enormous potential for applications such as virus inactivation and bacterial disinfection. The research results have been published in the journal Applied Physics Le...
