Digital Twin Simulations Toolbox of the Nitrogen‐Vacancy Center in Diamond

Advanced Quantum Technologies, EarlyView.
The Nitrogen‐vacancy (NV) center in diamond is a key platform within quantum technologies. This work introduces a Python based digital‐twin of the NV, where the spin dynamics of the system is simulated without relying on commonly used approximations, such as the adoption of rotating frame. The digital‐twin is validated through three different examples,

Development of Coupled Electrochemical Systems for Metal Resource Recovery From Aqueous Metal‐Organic Complexes

Rare Metals, EarlyView.
ABSTRACT The past decade has witnessed a burgeoning demand of metals for global industrial development and infrastructure. Meanwhile, the depletion of mineral resources and the environmental damage caused by wastewater discharges pose significant threats to both economic and ecological sustainability. Fortunately, metal‐containing wastewaters also hold

To Dye or Not to Dye: Unraveling the Impact of Surface Chemistry on Cerium Oxide Nanoparticles–Cell Interactions

Small Science, EarlyView.
Fluorescent dye labeling enables nanoparticle imaging but may subtly alter their surface chemistry and biological behavior. This study compares dye‐labeled and unlabeled cerium oxide nanozymes, revealing changes in cellular uptake kinetics without affecting their final intracellular fate. Combined fluorescence and label‐free electron microscopy imaging

Upconversion Photoluminescence to Monitor Local Heat Release During Femtosecond Direct Laser Writing of Bioinks In Situ

Small Methods, EarlyView.
Upconversion nanoparticle photoluminescence was used to quantify heat burden during femtosecond direct laser writing of bioinks in real time. Transient temperature spikes above 120–140°C demonstrate the need for a stringent process optimization, and fast 20 µm/s scan speeds were established to maintain physiological conditions.

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

Environmental Toxicology, EarlyView.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...
