Hybrid Quatsome‐Encapsulated Silver Nanoparticles as Stable Plasmonic Substrates for Surface‐Enhanced Raman Scattering

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.

Effects of gastric acid on surface roughness, microhardness, fracture strength, and color change of dental ceramics: A systematic review of in vitro studies

Journal of Prosthodontics, EarlyView.
Abstract Purpose This systematic review evaluated the effects of simulated gastric acid (SGA) on surface and mechanical properties of dental ceramics to answer the research question: Does immersion in SGA alter the surface roughness, microhardness, fracture strength, and color of dental ceramics?

Peripheral Inflammation and Sleep Loss Induce Coordinated Motivational Changes: An Experimental Two‐Hit Stress Model

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep loss and low‐grade inflammation are common stressors that affect behaviour and recovery needs. To examine their separate and combined effects on motivation for everyday behaviours, we developed a two‐hit experimental model. Participants (N = 56, 31 women) completed three experimental visits: sleep saturation (two nights, 9 h in bed/night)

Reaction-Diffusion Processes from Equivalent Integrable Quantum Chains

, 1997
One-dimensional reaction-diffusion systems are mapped through a similarity transformation onto integrable (and a priori non-stochastic) quantum chains. Time-dependent properties of these chemical models can then be found exactly.

Anisotropic fracture forming limit curves of aluminum alloy AA5052-H32 sheet [PDF]

AIP Conference Proceedings, 2020
Nowadays, the automotive industry aims to develop lighter vehicles, especially EVs. Thus, lightweight alloys such as aluminum sheets have been increasingly used to make various automotive panels. In this work, effects of material anisotropy on forming limit behaviour of AA5052-H32 aluminum sheet were investigated.

Biodegradable Materials Composed of PLA and High Load Triglycerides

Macromolecular Materials and Engineering, Volume 311, Issue 6, June 2026.
Transparent films of polylactic acid (PLA) was prepared with high sesame oil load (50% w/w). The cross‐section analysis of the films indicate that the oils are not absorbed into the polymer matrix; rather, they are stored as small droplets within the film.
