TL;DR: In this paper, the structural and electronic phase diagram of lithium and ethylenediamine intercalated FeSe in a wide range of dopant concentration was reported, and the dominant hole carrier in electron-doped FeSe tetrahedron was determined by using high-resolution neutron diffraction data at 5, 60, 150, and 295 K.

TL;DR: In this paper, a positive normal Hall coefficient is observed below the Curie temperature when the oxygen content of the film varies in a wide range, which may be attributed to the presence of excessive oxygen and composition distribution in the film.

TL;DR: In this article, a preparation method of blue titanium dioxide particles was proposed, which consisted of removing surface impurities of TiO2 particles, tabletting the TiO 2 particles treated in the step 1), so that the surfaces of the tabletted TiO II particles are flat, irradiating the Ti O 2 particles in step 2, for 3-10 seconds by using rapid laser with a pulsewidth of picoseconds or nanosecond, and uniformly mixing the II particles in the stage 3, again, and repeating the step 2 and the step 3, until the

TL;DR: In this article, a positive normal Hall coefficient is observed below the Curie temperature when the oxygen content of the film varies in a wide range, which may occur companying tetravalent ion doping.
