Isomeric Ag14 Nanoclusters With Distinct Photophysical and Nanomechanical Properties

open access: yesAdvanced Science, EarlyView.
Ligand‐shell isomerism in atomically precise Ag14 nanoclusters is demonstrated to regulate core distortion, photoluminescence, and mechanical properties. Subtle changes in phosphine ligand arrangement drive a pronounced emission shift from green to red and alter crystal rigidity, revealing a direct structure‐property correlation that offers new design ...

Molecular Dynamics‐Guided Sterol Engineering of mRNA‐Lipid Nanoparticles Reprograms Biodistribution and Enhances Spleen‐Selective Immunity

open access: yesAdvanced Science, EarlyView.
Sterol engineering enables precise control of mRNA lipid nanoparticles by tuning membrane organization. Replacing cholesterol with bile acid‐derived sterols redirects protein expression from the liver to the spleen. Notably, CA‐20 LNP enhances antigen‐specific immune responses while exhibiting a favorable safety profile, highlighting sterols as a ...

Hierarchical Physical‐Cyber Encryption via Metasurface‐Encoded Holographic Keys

open access: yesAdvanced Science, EarlyView.
ABSTRACT Physical‐layer encryption based on metasurfaces has emerged as a promising alternative to conventional algorithmic cryptography by embedding security into physical processes. However, most existing metasurface‐based encryption schemes operate within single‐stage or static frameworks, where correct physical illumination directly reveals the ...

La posizionalità come presupposto della relazionalità; e viceversa [PDF]

open access: yes
Both relational and positional goods are based upon an idea of joint consumption - thought with opposite signs. In both cases, agents are not self-regarded, but their consumption choices are other-regarded.

Circadian rhythm disruption as a potential contributor to BPPV: Evidence from a young rat model vestibular effects of circadian disruption.

open access: yesPLoS ONE
Circadian rhythm disturbances, increasingly common due to artificial lighting and modern lifestyle factors, may underlie vestibular dysfunction such as benign paroxysmal positional vertigo (BPPV), even in younger populations.
