Heat, Health and Holidays: Reported Heat Related Adjustments to Australian Tourist Behaviour
International Journal of Climatology, EarlyView.This study assessed how climate‐related hazards affect Australian tourists' travel planning. While 80% of tourists report no impact, the 20% who do experience disruption most commonly change their activities, timing, or destination, with heat and rain affecting the same proportion of tourists across beach, city, nature, and family tourism types ...

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.Abstract Metabolic dysfunction‐associated steatotic liver disease (MASLD) is the most common reason for elevated liver enzymes in children in Europe, affecting more than 5% of all children. Since the last iteration of this position paper, there have been substantial advances in our understanding of the disease.

Journal of Raman Spectroscopy, EarlyView.In this work, silver nanoparticles encapsulated within quatsome membranes have shown to preserve their plasmonic properties for at least 165 days without aggregation. These hybrid nanostructures enable strong SERS enhancement of pyrene and Prodan by confining the molecules within a few nanometers from the silver surface.

Near‐Infrared Polarimetric Imaging With Nonlinear Flat‐Optics
Laser &Photonics Reviews, EarlyView.ABSTRACT A compact and broadband polarimetric imaging platform is presented, based on second‐harmonic generation (SHG) in nonlinear flat‐optics. The system employs periodic all‐dielectric AlGaAs gratings to induce polarization‐dependent SH emission, enabling pixel by pixel direct retrieval of the full Stokes vector from an input intensity distribution ...

Multispectral Concentric Grafted Perfect Vector Vortex Beam
Laser &Photonics Reviews, EarlyView.Multispectral structured light offers powerful opportunities for increasing information capacity. A multispectral concentric grafted perfect vector vortex beam is proposed to engineer topological charges and polarization. A metasurface can graft different perfect vector vortex beams across concentric spatial regions and extend this concept to ...

Wavelength and Full‐Polarization Encrypted Orbital Angular Momentum Meta‐Holography
Laser &Photonics Reviews, EarlyView.By multiplexing three independent degrees of freedom of light, a single‐layer geometric‐phase metasurface encrypts 24 distinct holographic images across 3 wavelengths, 12 pairs of orthogonal polarizations, and 4 OAM channels, taking advantage of axial chromatic dispersion to reconstruct the color images at the same plane. ABSTRACT Multiplexing multiple

Diffraction‐Free Natural Optical Skyrmions and Their Subwavelength Confinement Around Vortices
Laser &Photonics Reviews, EarlyView.ABSTRACT Diffraction causes waves to spread out as they propagate freely. The tighter the lateral confinement, the faster the spreading. Past research on how to suppress diffraction has been based on wave engineering and has led so far to idealized waves that, in real settings, eventually diffract.

Generating Helical Polymorphic Beams Using Dielectric Metasurfaces
Laser &Photonics Reviews, EarlyView.Helix‐shaped polymorphic beams are optical fields whose intensity maxima spiral around the propagation axis, enabling particle manipulation through attractive or repulsive forces. Traditionally requiring expensive spatial light modulators, metasurfaces now provide a compact, cost‐effective alternative. This work demonstrates general helical polymorphic
