Scientific Reports is a peer-reviewed open-access scientific mega journal published by Nature Portfolio, covering all areas of the natural sciences. The journal was established in 2011. [1] The journal states that their aim is to assess solely the scientific validity of a submitted paper, rather than its perceived importance, significance, or ...
The letter highlights both the positive and negative effects of artificial intelligence. [65] According to Bloomberg Business, Professor Max Tegmark of MIT circulated the letter in order to find common ground between signatories who consider super intelligent AI a significant existential risk, and signatories such as Professor Oren Etzioni, who believe the AI field was being "impugned" by a ...
Laser-induced white emission (LIWE) is a broadband light in the visible spectral range.This phenomenon was reported for the first time by Jiwei Wang and Peter Tanner in 2010 for fully concentrated lanthanide oxides in vacuum, excited by a focused beam of infrared laser diode operating in continuous wave (CW) mode. [1]
Notable advantages of the technique include a high sensitivity, ease of calibration using a dielectric scattering sample, [2] good temporal resolution, low shot noise, non-intrusive probing, species-selectivity when coupled with resonance-enhanced multiphoton ionization (REMPI), single-shot acquisition, and the capability of time-gating due to ...
13 July – Researchers report the development of semitransparent solar cells that are as large as windows, [24] after team members achieved record efficiency with high transparency in 2020. [ 25 ] [ 26 ] On 4 July, researchers report the fabrication of solar cells with a record average visible transparency of 79%, being nearly invisible.
The coating window is a multivariable map of key process parameters, describing the range over which they can be applied together to achieve a defect-free film. Understanding the coating window behavior of a typical slot-die process enables operators to observe defects in a slot-die coated layer and intuitively determine a course of action for ...
The signal of SRS is free from the non-resonant background which plagues CARS microscopy, although a much smaller non-resonant background from other optical process (e.g. cross-phase modulation, multi-color multi-photon absorption) may exist. SRS can be detected in either the forward direction and epi directions.
If R 1 represents a clean freshly prepared surface (e.g., after a cleavage in vacuum) and R 2 the same sample after the exposure to hydrogen or oxygen contaminants, the ΔR/R spectrum can be related to features of the clean surface (e.g., surface states); [2] if R 1 is the reflectivity spectrum of a sample covered by an organic film (even if ...
