Global consensus on the management of melanin hyperpigmentation disorders

Journal of the European Academy of Dermatology and Venereology, EarlyView.
A global Delphi consensus of 10 dermatology experts established evidence‐based recommendations for melanin hyperpigmentation disorders, providing unified classification, photoprotection guidance and treatment algorithms. This framework harmonizes terminology and supports individualized management across diverse skin types and health systems.

Synthesis, Structure, and Eu3+‐Activated Photoluminescence of the Mixed‐Anion Carbodiimide NaLa2F3(CN2)2

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 4, 17 March 2026.
NaLa2F3(CN2)2 forms via solid‐state metathesis of LaF3 and Na2(CN2) at 550°C and remains stable under ambient air and humidity. The structure is based on [La(NCN)5F4] polyhedra with interstitial Na+; revealing an unconventional red emission when doped with Eu3+.

Active Switching of Orbital Angular Momentum of Light Using Metasurfaces Incorporating Vanadium Dioxide

Nanophotonics, Volume 15, Issue 5, 16 March 2026.
This work presents a novel design strategy for active metasurfaces that actively switches OAM modes. The metasurface integrates VO2 within MIM meta‐atoms. Operating at 1500 nm, the designed platform enables large leaps in topological charge. For instance, the reflected beam can be switched from a topological charge of −1 in the insulating (M1) phase to

Wavelength Dependence of fs Laser Ablation Ionisation Mass Spectrometry: a Dedicated Study on NIST SRM 664

Rapid Communications in Mass Spectrometry, Volume 40, Issue 5, 15 March 2026.
ABSTRACT Rationale Laser ablation mass spectrometry provides fast and direct chemical information of solids with high spatial resolution without the need for complex sample preparation. It has been shown that reducing the laser pulse length below picoseconds improves the quantification of chemical composition measurements of solids. This study compares
