Simultaneous radionuclide determination using PSresin: 2in2 and 2in1 tandem configuration.

Background: Analyzing mixtures of radionuclides is a complex task. Two situations are the mixtures of Sr with Sr and Sr with plutonium isotopes. The challenge arises in emergency scenarios resulting from accidents where the activity of Sr is over 20 times higher than that of Sr, complicating its quantification and requiring delayed measurements.

Iono-Optic Impedance Spectroscopy (I-OIS): A Model-Less Technique for In Situ Electrochemical Characterization of Mixed Ionic Electronic Conductors.

Functional properties of mixed ionic electronic conductors (MIECs) can be radically modified by (de)insertion of mobile charged defects. A complete control of this dynamic behavior has multiple applications in a myriad of fields including advanced computing, data processing, sensing or energy conversion. However, the effect of different MIEC's state-of-charge is not fully understood yet and there is a lack of strategies for fully controlling the defect content in a material.

Solid-State Oxide-Ion Synaptic Transistor for Neuromorphic Computing.

Neuromorphic hardware facilitates rapid and energy-efficient training and operation of neural network models for artificial intelligence. However, existing analog in-memory computing devices, like memristors, continue to face significant challenges that impede their commercialization. These challenges include high variability due to their stochastic nature.

Performance Prediction of High-Entropy Perovskites LaSrMnCoFeO with Automated High-Throughput Characterization of Combinatorial Libraries and Machine Learning.

Perovskite oxides form a large family of materials with applications across various fields, owing to their structural and chemical flexibility. Efficient exploration of this extensive compositional space is now achievable through automated high-throughput experimentation combined with machine learning. In this study, we investigate the composition-structure-performance relationships of high-entropy LaSrMnCoFeO perovskite oxides (0 < x, y, z <1; x+y+z≈1) for application as oxygen electrodes in Solid Oxide Cells.
