Evaluation of the Dual Impact of Nanotechnologies on Health and Environment Through Alternative Bridging Models

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 15, 17 April 2026.
This review explores how alternative invertebrate and small‐vertebrate models advance the evaluation of nanomaterials across medicine and environmental science. By bridging cellular and organismal levels, these models enable integrated assessment of toxicity, biodistribution, and therapeutic performance.

Large-scale production of ferromagnetic nanorings by a modified hole-mask colloidal lithography: Controlled creation of flux-closure vortex state

open access: yesAIP Advances, 2016
Large arrays of ferromagnetic nanorings are produced by a modified hole-mask colloidal lithography and ring dimension can be modulated to create flux-closed vortex, known as a dipole-free magnetic state with a low crosstalk arising from neighboring ...

Science‐Towards‐Technology Breakthrough in CO2 Electroreduction: Multiphysics, Multiscale, and Artificial Intelligence Insights

open access: yesAdvanced Materials, Volume 38, Issue 22, 17 April 2026.
Electrochemical CO2RR is a key technology for converting CO2 into chemicals, but there remains a gap between “laboratory science” and “engineering practice” in current research. This review establishes a multi‐scale research framework, encompassing atomic‐level characterization, microenvironment regulation, external field‐assisted optimization, and AI ...

Room Temperature Synthesis and Photopatterning of Mesoporous Titanium Dioxide Thin Films

open access: yesAdvanced Materials Technologies, Volume 11, Issue 7, 6 April 2026.
A nanofabrication strategy combining deep‐UV photolithography with block copolymer self‐assembly enables direct patterning and mineralization of mesoporous TiO2 thin films at room temperature. Photocatalytic titanium oxo‐clusters promote polymer degradation under UV irradiation, enabling multiscale control over porosity, film thickness, and lateral ...

Long-lived circulating currents in strongly correlated nanorings

open access: yesPhysical Review Research, 2019
We study the time-evolving currents flowing in an interacting ring-shaped nanostructure after a bias voltage has been switched on. The source-to-drain current exhibits the expected relaxation towards its quasistatic equilibrium value at a rate Γ_{0 ...

Ordered GeSi nanorings grown on patterned Si (001) substrates

open access: yesNanoscale Research Letters, 2011
An easy approach to fabricate ordered pattern using nanosphere lithography and reactive iron etching technology was demonstrated. Long-range ordered GeSi nanorings with 430 nm period were grown on patterned Si (001) substrates by molecular beam epitaxy ...
