Summary: This paper presents developments in improving silicon sensor technology for the detection of soft X-rays with hybrid X-ray detectors. An optimization of the entrance window technology is required to enhance the quantum efficiency. By using LGAD technology, the signal generated by X-rays can be amplified, leading to an improved signal-to-noise ratio and enabling single photon resolution in the soft X-ray energy range. The results demonstrate successful single photon detection of soft X-rays down to 452 eV, with a signal-to-noise ratio better than 20.

Summary: In this study, attosecond afterburners are implemented in an ultrashort soft X-ray free-electron laser to enhance the generation of attosecond pulses. By dumping the FEL pulse produced in the normal radiator section and reusing the well bunched electron beam in downstream afterburners, the radiation in the afterburners gains rapidly and results in shorter and cleaner pulses compared to a normal radiator. Multi-shot simulations demonstrate the performance and stability of this proposed technique.

Summary: A recently proposed concept allows for obtaining much shorter pulses in Self-Amplified Spontaneous Emission Free Electron Lasers (SASE FELs) by suppressing radiation in the long main undulator while preserving microbunching within a shorter lasing slice. The method of excessive reverse undulator taper is discussed and illustrated numerically in this paper, with first experimental tests performed at the soft X-ray FEL user facility FLASH. The measured pulse duration approaches 1 fs (FWHM) at the wavelength of 5 nm.

Summary: Estuarine mangrove wetlands are considered a major source of methane emissions, with anaerobic methane oxidation (AMO) being an important pathway for reducing these emissions. This study found that nitrite-AMO is a significant methane sink in mangrove ecosystems, contributing the most among all AMO processes examined. Additionally, temporal and spatial variations in the nitrite-AMO bacterial distribution, abundance, activity, and sensitivity to environmental factors were investigated.

The study found that the irradiated areas in the (Al-)Schottky type sensors showed a more robust charge collection compared to unirradiated areas, while no alteration of the polarization characteristics was found in the ohmic type CdTe sensors after irradiation.

Summary: X-ray photoelectron spectroscopy of BSA in a liquid jet provides insights into the electronic structure and charge transfer mechanisms in biological systems. The spectra show no structural damage to BSA and reveal carbon and nitrogen atoms in different chemical environments. Comparison between solid and solvated BSA shows higher sensitivity of valence bands to solvation effects. The ionization energy of solvated BSA is determined as 5.7 +/- 0.3 eV. Experimental results are compared with theoretical calculations, highlighting the role of water in hole delocalization in proteins.
