The Low Density Matter (LDM) beamline has been built as part of the FERMI free-electron laser (FEL) facility to serve the atomic, molecular and cluster physics community. After the commissioning phase, it received the first external users at the end of 2012. The design and characterization of the LDM photon transport system is described, detailing the optical components of the beamline.

Two-dimensional (2D) nanofluidic architectures with nanoconfined interlayer channels and excess surface charges have revolutionized membrane-based reverse electrodialysis systems, demonstrating highly efficient osmotic energy collection through strong electrostatic screening of electric double layer (EDL). However, the ion-transport dynamics in 2D nanofluidic anion-selective membranes (2D-NAMs) still remain unexplored. Here, we combine density functional theory and molecular dynamics (MD) simulations to systematically explore ion transport in the 2D-NAMs.

Dyslipidemia is considered a crucial risk factor for high risk of atherosclerosis and cardiovascular diseases. Cumin and coriander seeds are well-known flavoring agents that contain nutraceutical properties and appear to have beneficial health effects. A study was therefore conducted to investigate the effects of cumin and coriander seeds on body weight, abdominal fat and lipid profile in rats.

We report here the first measurements of the electron drift mobility μ in gaseous H2 in the intermediate density range 0.5 × 1026 m-3 ≤ N ≤ 5 × 1026 m-3, at low temperature, T = 49.7 K and T = 29.

Accurately modeling volume-dependent properties of water remains a challenge for density functional theory (DFT), with widely used functionals failing to reproduce key features of the water density isobar, including its shape, density, and temperature of the density maximum. Here, we compare the performance of the RPBE-D3 and vdW-DF-cx functionals using replica exchange molecular dynamics (MD) driven by machine-learned force fields. Our simulations reveal that vdW-DF-cx predicts the water density more accurately than RPBE-D3 and reproduces the isobar closely between 307 and 340 K.

Nitrogen leaching is a major pathway of nitrogen fertilizer loss. Although arbuscular mycorrhizal (AM) fungi are known to reduce nitrogen leaching by improving plant nitrogen uptake, the soil-based mechanisms remain unclear. A pot experiment was conducted using a randomized complete block design, with four nitrogen levels (0, 3.
