Singularities in the flying electromagnetic doughnuts

Nanophotonics, 2019
Flying doughnuts (FDs) are exact propagating solutions of Maxwell equations in the form of single-cycle, space-time non-separable toroidal pulses. Here we review their properties and reveal the existence of a complex and robust fine topological structure.

Synchrotron beamline setup enabling quasi‐simultaneous PXRD and XANES measurements: case study of Fischer–Tropsch catalyst reduction at 60 bar

Journal of Synchrotron Radiation, EarlyView.
This paper presents a beamline setup that allows the combination of in situ powder X‐ray diffraction (PXRD) and X‐ray absorption near‐edge structure (XANES) measurements within a single experimental cycle to investigate cobalt catalyst structures and properties under real conditions.Powder X‐ray diffraction (PXRD) and X‐ray absorption near‐edge ...

Comparison of a Miniaturized Implantable Two‐Stage Rotodynamic Blood Pump to Equivalent Single‐Stage Concepts

Artificial Organs, EarlyView.
This study aims to evaluate the potential of a multistage pump design to enhance hemocompatibility in left ventricular assist devices. We found that the two‐stage concept offers favorable hemolysis measures compared to single‐stage designs, as the reduction in peak shear stresses outweighs the disadvantage associated with prolonged residence time ...

Probability backflow for a Dirac particle

, 1998
The phenomenon of probability backflow, previously quantified for a free nonrelativistic particle, is considered for a free particle obeying Dirac's equation. It is known that probability backflow can occur in the opposite direction to the momentum; that

Compact Tubular Dielectric Elastomer Pump for Indoor Plants

Journal of Applied Polymer Science, Volume 143, Issue 25, July 5, 2026.
This study develops a mountable rolled dielectric elastomer pump (MRDEP) using silicone films and MWCNT‐based electrodes. The MRDEP is completely soft, silent in operation, and easily mounted on a piping system. We use dry stacking methods, fabricate a multilayer dielectric elastomer actuator (DEA), and a pre‐straining process in one direction before ...

Highly Efficient and Salt‐Tolerant Broom‐like Bamboo Solar Evaporator: Constructing Multiscale Open Gaps to Enhance Water Transportation and Vapor Diffusion

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
A bamboo fiber aggregation‐based broom‐like evaporator with open interstitial spaces for water transport and vapor diffusion was designed that provided extensive air–liquid interfaces for facilitating fast vapor diffusion and avoiding the formation of high‐humidity zones.

The L108I polymorphism in mouse prion protein drives spontaneous disease and enhances transmission of atypical and classical prion strains

Brain Pathology, Volume 36, Issue 4, July 2026.
A single amino acid change (L108I) combined with PrP overexpression drives spontaneous atypical prion formation in mice, enabling also efficient propagation of diverse prion strains. This model allows studying how spontaneous prion diseases arise and provides powerful tools for investigating strain emergence, transmission barriers, and mechanisms ...
