Morphological and Hyperphosphorylation Transitions of Nanoscale Tau Aggregates in Alzheimer's Disease

open access: yesAdvanced Science, Volume 13, Issue 6, 30 January 2026.
Super‐resolution microscopy identifies nano‐sized tau aggregates (nano‐aggregates) and reveals distinct transitions in their morphology and phosphorylation profiles across control, Primary Age‐Related Tauopathy, and Alzheimer's disease brains. Morphology and hyperphosphorylation signatures distinguish physiological from pathological forms, with nano ...

Membrane patterned by pulsed laser micromachining for proton exchange membrane fuel cell with sputtered ultra-low catalyst loadings [PDF]

open access: yes, 2015
International audienceProton exchange membranes were nano-and micro-patterned on their cathode side by pressing them against stainless steel molds previously irradiated by a Ti:Sapphire femtosecond laser. The membranes were associated to ultra-low loaded

Dynamic Mechanisms of the Bactericidal Action of an Al2O3-TiO2-Ag Granular Material on an Escherichia coli Strain. [PDF]

open access: yes, 2015
The bactericidal activity of an Al2O3-TiO2-Ag granular material against an Escherichia coli strain was confirmed by a culture-based method. In particular, 100% of microorganisms were permanently inactivated in 30 to 45 min.

Polyoxometalate‐Based Au–Ag Alloy Nanocatalysts for Efficient Electrochemical CO2 Reduction Reaction

open access: yesChemCatChem, Volume 18, Issue 2, 28 January 2026.
Au–Ag alloy nanocatalysts derived from a Ba2+ salt of an Au–Ag alloy nanocluster‐incorporated polyoxometalate (POM) efficiently catalyze electrochemical CO2 reduction reaction (CO2RR) and achieve the highest carbon monoxide productivity among the POM‐based CO2RR catalysts.

Excitonic Wave Function Reconstruction from Near-Field Spectra Using Machine Learning Techniques

open access: yes, 2019
A general problem in quantum mechanics is the reconstruction of eigenstate wave functions from measured data. In the case of molecular aggregates, information about excitonic eigenstates is vitally important to understand their optical and transport ...

Aggregation and sedimentation of shattered graphene oxide nanoparticles (SGO) in dynamic environments: a solid-body rotational approach [PDF]

open access: yes, 2018
Nanoparticle (NP) aggregation is typically investigated in either quiescent or turbulent mixing conditions; neither is fully representative of dynamic natural environments.

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

open access: yesAdvanced Materials, Volume 37, Issue 48, December 3, 2025.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Synthesis and characterization of surface-enhanced Raman-scattered gold nanoparticles [PDF]

open access: yes, 2013
In this paper, we report a simple, rapid, and robust method to synthesize surface-enhanced Raman-scattered gold nanoparticles (GNPs) based on green chemistry. Vitis vinifera L. extract was used to synthesize noncytotoxic Raman-active GNPs.

Development, Efficiency, and Impact Factors of Phosphorus Nanofertilizers in Agriculture: A Review

open access: yesJournal of Plant Nutrition and Soil Science, Volume 188, Issue 6, Page 894-912, December 2025.
Overview of the potential benefits of phosphorus nanofertilizers in agriculture. ABSTRACT Modern intensive agriculture to feed the growing population of the world has been practiced in view of the limitations of arable land and water resources. However, overapplication of chemical fertilizers may pose severe environmental impacts, including soil ...
