Ultrafast optical excitation is widely used to manipulate electronic and magnetic properties of materials on femtosecondtimescales. In this study, we investigate the response of copper to circularly polarized femtosecond pulses using time-resolvedmagneto-optical Kerr effect measurements. [...]

Formation of a eutectic AuSi compound was observed during the solid state dewetting and agglomeration in a Ni–Au bilayer thin film grown on a Si3N4 substrate using coherent X-ray diffractive imaging, X-ray diffraction, and scanning electron microscopy. During rapid thermal annealing at 850 °C in vacuum, AuNi films first separate into islands that are composed of a mixture of Au-rich and Ni-rich phases. [...]

Variational Quantum Eigensolver (VQE) is widely used in near-term hardware. However, their performances remain limited by the poor trainability and are dependent on random parameter initialization. [...]

Supercrystalline nanocomposites (SCNCs) are nanostructured hybrid materials with unique emergent functional properties. Given their periodically arranged building blocks, they also offer interesting parallelisms with crystalline materials. [...]

We present a diode-pumped continuous-wave (CW) Yb:YVO4 laser exhibitingwavelength tunability from 986 nm to 1119 nm, corresponding to a broad tuning range of133 nm, one of the widest reported for any Yb-doped laser host. This performance was achievedby employing a low-loss, off-surface optic-axis birefringent filter, high-quality laser crystals,and optimized low-loss cavity optics, enabling smooth and stable wavelength tuning along bothprincipal polarization axes (E//a: 986-1084 nm and E//c: 995-1119 nm).

Serial crystallography (SX) is a powerful method for determining macromolecular structures, enabled by the advent of X-ray free-electron lasers (XFELs). SX experiments require the continuous delivery of microcrystals, achievable through liquid jets, high-viscosity extrusion (HVE) jets, and fixed-target methods. [...]

The title compound, [CoII(C3N2H4)6]3·[C9H3O6]2 (1), was synthesised from cobalt chloride(II), benzene-1,3,5-tricarboxylic acid (H3btc) and imidazole (Im) in an ethanol/DMF mixture via slow evaporation at room temperature. The structure of 1 is here reported. [...]

AbstractThe development of serial crystallography (SX), including serial synchrotron crystallography (SSX) at synchrotron sources and serial femtosecond crystallography (SFX) at X-ray free-electron lasers (XFELs), has facilitated the collection of high-resolution diffraction data from micron-sized crystals, providing unique insights into the structures and dynamics of biomolecules at room temperature. Standard samples are essential for the commissioning of new XFEL instruments and the validation of experimental setups [...]

Compressible turbulence governs energy transfer across scales in space and astrophysical systems. Capturing both the turbulence cascade and damping is therefore crucial for models of energy conversion, plasma heating, and particle transport in diverse plasma environments, but it remains challenging.
