TL;DR: In this article, a simple method is proposed to extend the photon energy range of a soft x-ray self-seeding free-electron laser (FEL) by using a normal monochromator to purify the FEL spectrum and provide a coherent seeding signal.

TL;DR: The results showed that the performance status of HiRIC meets the requirements of obtaining high resolution images on the Martian surface and proposals for HiRIC in-orbit imaging strategy and data processing are discussed to ensure the acquisition of high-quality HiRIC images, which is expected to serve as a powerful complementation to the current Mars high-resolution images.

TL;DR: In this article, a simple approach to introduce the intermediate band through substituting tin by p-block metalloid antimony in SnS2 was proposed, and two absorption edges appeared at 2.31 eV and 1.63 eV in the visible light region, and one absorption shoulder starting at 0.68 eV emerged in the infrared region, as observed from the UV and NIR absorption spectra.

TL;DR: It is shown in this paper it is possible to generate only one droplet per gridded area on a thin film subsequent to nucleation dominated dewetting on a non-patterned substrate when the grid periodicity exceeds the spinodal length, and the number of droplets in predefined areas gradually approaches that associated with unconfined deWetting.

TL;DR: In this article, the dependences of high harmonic micro-bunching in the high gain harmonic generation (HGHG), echo-enabled harmonic generation and phase-merging enhanced harmonic generator (PEHG) schemes on the electron energy spread distribution are studied.
