1 day ago · The defect density essentially attenuates at spot 5, suggesting that there is significant defect generation in the outer ring region, at ∼13.1 m, from the primary ablation region. This result demonstrates that point defects can be generated not only in the primary ablation and rippled regions of the LIPSS, but also in the outer region.
1 day ago · Rutherford scattering or Coulomb scattering is the elastic scattering of charged particles by the Coulomb interaction. The paper also initiated the development of the planetary Rutherford model of the atom and eventually the Bohr model. Rutherford scattering is now exploited by the materials science community in an analytical technique called ...
3 days ago · Generate a FITS sky map file from posterior samples using clustering and kernel density estimation. The input file should be an HDF5 file with the following columns: ra, rightascension, or right_ascension: J2000 right ascension in. radians. dec or declination: J200 declination in radians.
4 days ago · Recently, 3D label-free super-resolution profilers based on microsphere-assisted scanning white light interferometry were introduced having vertical resolution of few angstroms (Å) and a lateral resolution approaching 100 nm. However, the use of a single microsphere to generate the photonic nanojet (PNJ) limits their field of view. We overcome this limitation by using polymer microfibers to ...
2 days ago · Fig. 5 c presents the continuous temperature changes of four samples from 9:30 am to 1:00 am (the next morning) under cloudless sky, the TiO 2 /SEBS, TiO 2 /SEBS‖PCM/SEBS and STATR textiles show obvious passive cooling performance in the daytime when compared to pure SEBS, which is mainly attributed to the reflection of TiO 2 nanoparticles in ...
1 day ago · The following is a list of significant formulae involving the mathematical constant π. Many of these formulae can be found in the article Pi, or the article Approximations of π. Euclidean geometry. where C is the circumference of a circle, d is the diameter, and r is the radius. More generally,
1 day ago · It caused an R3 (strong) radio blackout affecting an area over the Pacific Ocean northeast of Micronesia. According to a data base at SpaceWeatherLive.com, it was the 26th largest flare...
