Spin density wave and van Hove singularity in the kagome metal CeTi3Bi4
Single-crystal neutron diffraction
The antiferromagnetic order in CeTi3Bi4 was determined via single-crystal neutron diffraction measurements conducted at multiple diffractometers (see “Methods”). All diffraction data in this study are…

Investigation of the mechanical frequency response of ovine renal tissue at low frequencies
The kidneys are paired retroperitoneal organs responsible for filtering blood and regulating the ionic balance of extracellular fluid. Each kidney comprises modular units known as nephrons, which consist of a glomerulus for filtration and a…

Advancing inorganic electro-optical materials for 5 G communications: from fundamental mechanisms to future perspectives
The development of EO materials has seen key milestones over the past century. Ferroelectricity was first experimentally discovered a century ago, leading to Valasek’s 1920 study on Rochelle salts showing their ferroelectric domains under…

Photon–photon chemical thermodynamics of frequency conversion processes in highly multimode systems
Theory
To formulate the aspects governing these optical “chemical reactions”, we begin by considering an exemplary frequency generation process in an arbitrary multimoded optical system. In the case under consideration, let us assume that the…
