Exact inversion of partially coherent dynamical electron scattering for picometric structure retrieval
Exact inversion of partially coherent phaseless scattering data The frozen phonon (FP) approach translates time-dependent potentials V(r, t) arising from the thermal motion of atoms, to an incoherent superposition of different stationary states Vi(r). Figure 1a exemplifies this concept via the projected potentials of two slices \({V}_{{{{{{{{\rm{FP}}}}}}}}}^{(1,2)}({{{{{{{\bf{r}}}}}}}})\) in a ferroelectric PbZr0.2Ti0.8O3 (PZT) crystal. The potentials contain thermal…

Antiferromagnetic interlayer exchange coupled Co68B32/Ir/Pt multilayers
Two SAF systems grown via magnetron sputtering (see “Methods” section) are probed for this work. When engineering these systems, it is crucial to extract the thickness of the materials, especially the Ir thickness required to induce the AFM coupling. These thicknesses were computed by doing low angle X-ray reflectometry scans, and fitting them with GenX48…

3D integral imaging of acoustically trapped objects
Acoustic trapping The acoustic wave is mechanical and longitudinal, and the superposition of two acoustic waves forms a standing wave. In standing waves, the mechanical wave creates acoustic pressures along the propagating direction, therefore, any standing wave includes a number of nodes and anti-nodes, and the nodal points may be used for AT29. However, there…

Towards a transferable fermionic neural wavefunction for molecules
In the following, we briefly outline our approach and how it extends existing work (A multi-compound wavefunction ansatz). We show the fundamental properties of our ansatz such as extensivity and equivariance with respect to the sign of reference orbitals. We demonstrate the transferability of the ansatz when pre-training on small molecules and re-using it on…

Thermal and optical properties of P3HT:PC70BM:ZnO nanoparticles composite films
X-Ray diffraction In order to examine the presence of ZnO-NPs in composite films, impact of thermal annealing and to determine the effect of the polymer molecular weight on the microstructure of composite films, we conducted detailed X-ray diffraction studies, which included powders of purchased materials and films obtained from their mixtures with an increasing number…

Field-induced compensation of magnetic exchange as the possible origin of reentrant superconductivity in UTe2
We investigated several micron-sized samples produced from one oriented single crystal with a superconducting Tc of 1.6 K. The micromachining was performed by means of Ga or Xe FIB systems (for details, see the methods section). This FIB approach enables precise geometries suitable for microcantilever-torque experiments on magnetic materials with strong torque responses as well as…

Colloidal pathways of amorphous calcium carbonate formation lead to distinct water environments and conductivity
Materials All solutions were prepared using Milli-Q water that was degassed by bubbling N2 through the solution overnight to remove dissolved CO2. 20 mM CaCl2 and 20 mM NaOH solutions were prepared by dilution of CaCl2 stock solution (1.0 M, VWR, AVS Titrinorm volumetric solution) and NaOH stock solution (0.1 N, Carl Roth), respectively. Carbonate buffer solutions were freshly…
