Smart Nanotechnologies for Multimodal Neuromodulation and Brain Interfacing

open access: yesAdvanced Science, EarlyView.
Recent advances in smart nanotechnologies are expanding the toolbox for brain interfacing, from wireless neuromodulation and high‐resolution sensing to targeted delivery within the central nervous system. By combining responsive nanomaterials with bioinspired design, these platforms enable multimodal interactions with neurons and glia, while also ...

Analytic Modeling, Simulation and Interpretation of Broadband Beam Coupling Impedance Bench Measurements

open access: yes, 2014
In the first part of the paper a generalized theoretical approach towards beam coupling impedances and stretched-wire measurements is introduced. Applied to a circular symmetric setup, this approach allows to estimate the systematic measurement error due

Magnetoelectric Nanoparticle‐Based Wireless Brain–Computer Interface: Underlying Physics and Projected Technology Pathway

open access: yesAdvanced Science, EarlyView.
Magnetoelectric nanoparticles (MENPs) enable fully wireless, minutely invasive neuromodulation, and potentially neural recording, by converting magnetic into electric and, conversely, electric into magnetic fields, respectively, at high spatiotemporal resolution.

Tuning Defects in Ni‐Doped Maghemite for Enhanced Solar Driven Oxygen Evolution: Insights From Operando X‐Ray Spectroscopies

open access: yesAdvanced Science, EarlyView.
ABSTRACT Maghemite (γ$\gamma$‐Fe2${\rm Fe}_2$O3${\rm O}_{3}$) is a promising non‐precious‐metal‐containing photocatalyst for water oxidation (OER). Despite being less studied than Hematite, it offers similar corrosion resistance and a favorable band structure, along with higher conductivity and the advantage of an adaptable spinel structure.

Wireless, Adaptable and Fully Implantable Battery‐powered Devices for Optical Stimulation of the Spinal Cord in Small Rodents

open access: yesAdvanced Science, EarlyView.
Current technologies for spinal cord optogenetic stimulation rely on external power sources and face reliability constraints in freely behaving animals. Here, a fully implantable, battery‐powered optoelectronic device is introduced, enabling operation in any selected environment with wireless recharging for months‐long stimulation.

Co-Doped (Na<sup>+</sup>, Mg<sup>2+</sup>, Zn<sup>2+</sup>, Fe<sup>3+</sup>)-Carbonated Hydroxyapatites and Composites with M<sup>II</sup>Fe<sub>2</sub>O<sub>4</sub>: Synthesis, Mechanic, Magnetic, and Antibacterial Properties for Medical Application. [PDF]

open access: yesChemistryOpen
Multi‐doped (Na+, Mg2+, Zn2+, CO32‐) hydroxyapatite/ferrite composites were synthesized via a one‐stage method. These “smart” materials exhibit high microhardness (3.28 GPa), potent antimicrobial activity, and membrane‐stabilizing effects, reducing erythrocyte hemolysis by up to 25%.
