Effect of Nanoparticle Distribution on Photothermal Absorption in Binary Mixtures of Colloidal Supraballs

open access: yesAdvanced Photonics Research, EarlyView.
This work combines molecular dynamics and finite‐difference time‐domain computational approaches to study the photothermal properties of melanin nanoparticle–based supra‐assemblies. Based on the results of this study, the binary mixtures of melanin and silica with higher concentrations of melanin and with more segregated levels of mixing are able to ...

Optimal control on a metric graph for a damped linear fractional hyperbolic problem

open access: yesResults in Control and Optimization
The optimal control of fractional PDEs has been extensively studied in standard domains, but the existence and uniqueness of optimal controls in metric graphs, particularly for hyperbolic equations, remain less explored.

Realization of Aqueous Processed LiNi0.5Mn1.5O4 through the pH Optimization of Polyacrylate Binders

open access: yesAdvanced Sustainable Systems, EarlyView.
Partly neutralized polyacrylate binders enable aqueous processing of LiNi0.5Mn1.5O4 (LNMO) cathodes by buffering the slurry pH within the aluminum current collector's passivation region. Optimal performance is achieved at binder pH 5, matching polyvinylidene difluoride (PVDF)‐based systems in LNMO‖Li4Ti5O12 (LTO) full cells, while higher pH leads to ...

Automated Transcranial Photobiomodulation in Healthy Rats: Effects on Working Memory and Brain Markers

open access: yesAdvanced Therapeutics, EarlyView.
Transcranial photobiomodulation (PBM) enhances spatial working memory in healthy rats under both continuous and alternating stimulation protocols. At the neural level, PBM modulates cytochrome c oxidase activity, increases prefrontal and hippocampal synaptic markers, and induces region‐specific c‐Fos expression. These effects suggest improved cognitive
