source：azoopticsPulsed lasers, a crucial component of the laser industry, are continuously developed to produce higher repetition frequencies and greater intensity. Recently published research findings from the Shanghai Institute of Optics and Fine Mechanics at the Chinese Academy of Sciences exhibit a crystal with promising pulsed laser properties. Research efforts led by the group of Professor Yin Hang and published in Optics & Laser Technology have demonstrated the first laser operation of perovskite oxide LaAlO3 doped with 0.1 at% Nd ions and 0.2 at% Th (Nd,Th:LaAlO3).What are Pulsed L...

source:natureAbstractThe current work is mainly devoted to the synthesis, structural, electrical, and magnetic characterization of Sr1−XLaXFe12O19 (X = 0.2–0.8) (SLFO) nanoparticles synthesized via the hydrothermal technique. The hexagonal peaks were determined using X-ray diffraction analysis. The obtained results indicated that the lattice constants were noted to be increasing from 0.58801 to 0.58825 nm (a = b), and 2.30309 to 2.30341 nm (c) with increase of in ‘X’. The morphological studies ensured that the grains as well as nanoparticles of SLFO acquired almost spherical shape. The optical...

Rare Mineral from Martian Crater was Created in Explosive Volcanic Eruption Over 3 Billion Years Agosource:sci-newsTridymite is a high-temperature, low-pressure form of quartz that is extremely rare on Earth, and it wasn’t clear how a chunk of it ended up in Gale Crater on Mars, the home of NASA’s Curiosity rover.Gale Crater, which is at least 3.8 billion years old, was chosen as Curiosity’s landing site due to the likelihood that it once held liquid water, and the rover found evidence that confirmed Gale Crater was a lake as recently as 1 billion years ago.In July 2015, Curiosity drilled into...
