Summary: X-ray crystallography is currently the dominant method for determining the structure of proteins and biomolecules. However, it faces challenges in obtaining high-resolution data from small protein crystals. Serial crystallography using XFELs is a promising alternative method that can produce excellent structural data from weakly diffracting objects. In this study, the authors calculate the mean crystal size and growth time needed for batch crystallization, which is the main method for preparing microcrystalline slurries. They also consider the impact of impurities on the growth of microcrystals. Experimental results with lysozyme support the theoretical predictions.

Summary: Our study on ultrafast carrier-induced lattice contractions and interlayer modulations in Bi2Se3 thin films sheds light on the topological phase control by light-induced structural change on ultrafast time scales. The lattice contraction depends on carrier concentration and is followed by interlayer expansion, providing insights into topological phase transition modulation.

Summary: Reticular chemistry of covalent organic frameworks (COFs) focuses on linking discrete organic building units into extended structures through strong covalent bonds. Over the past decade, there has been rapid development in COF chemistry in terms of structural diversity and applications. Understanding the concept of reticular chemistry is essential for researching COFs and correlating their geometric structures and practical applications.

Summary: In this study, the crystal structure of a new polymorph of l-tyrosine (denoted the beta polymorph) prepared by vacuum sublimation was reported. The combined analysis of 3D electron diffraction data and powder X-ray diffraction data was used for structure determination and refinement. DFT-D calculations and crystal structure prediction calculations were performed to validate the results and explore other possible crystalline polymorphs.

Summary: Dielectric laser accelerators (DLAs) show promise for economic and compact on-chip radiation sources by utilizing silicon industry fabrication capabilities and breakthroughs in silicon-photonic nanostructures. Recent research has demonstrated the quantum nature of DLAs, revealing quantized peaks in electron-energy spectra and showcasing quasi-phase-matching between electron and light waves. The use of ultrafast transmission electron microscopy (UTEM) allows for extended electron-light interaction lengths, highlighting the potential for manipulating particles' quantum wave functions in accelerator physics.

Summary: An important trend in recent years has been the use of an external laser as seeding to improve the coherence and stability of free-electron laser pulses, with high-gain harmonic generation seeding technique achieving high coherence and stability at FERMI. The seed laser also plays a crucial role in pump-probe experiments at FERMI, helping achieve record-low timing jitter.
