Enhanced Resistive Switching Uniformity in Tantalum Oxide Memristor Devices via Copper Implantation

Advanced Electronic Materials, EarlyView.
Metal oxide memristor devices typically suffer from uncontrolled forming processes and limited resistive switching uniformity due to the stochastic formation of an oxygen vacancy filament. Improved resistive switching uniformity in Ta2O5 memristor is developed by Cu implantation in the switching oxide.

Retinoic acid induces PGI synthase expression in human endothelial cells

Journal of Lipid Research, 2008
Retinoic acid (RA) exhibits anti-inflammatory, anti-tumor, and immuno-modulatory actions, and affects angiogenesis and thrombosis. Arachidonic acid (AA) metabolites are involved in all these processes.

Organic pollution in PGI and non-PGI lemons and related soils from Italy and Turkey

Natural Product Research, 2018
In this work 67 organic contaminants in Protected Geographical Indication (PGI) and non-PGI Interdonato Lemon pulps, peels, leave and related soils were evaluated by GC/MS-MS. It is possible to highlight that in Italian pulps and peels the residues were under LODs (0.10–10.30 ng·g−1), whereas the leaves showed piperonyl butoxide in 33% of samples (11 ...

Bdellovibrio bacteriovorus phosphoglucose isomerase structures reveal novel rigidity in the active site of a selected subset of enzymes upon substrate binding

Open Biology, 2021
Glycolysis and gluconeogenesis are central pathways of metabolism across all domains of life. A prominent enzyme in these pathways is phosphoglucose isomerase (PGI), which mediates the interconversion of glucose-6-phosphate and fructose-6-phosphate.

Comparative Analysis of Model‐Agnostic Explanation Methods in Materials Science

Advanced Intelligent Systems, EarlyView.
To address the critical lack of explainable artificial intelligence (XAI) benchmarks in materials science, we present a quantitative and qualitative analysis of six XAI methods applied to molecular fingerprints. Our results reveal significant discrepancies in feature importance rankings, demonstrating that the chosen explanation approach introduces ...

Nullwertige Nickelatome stabilisiert in oberflächengestützten metallorganischen Ketten

Angewandte Chemie, EarlyView.
Mit 9,10‐Dicyanoanthracen koordinierte nullwertige Ni(0) d10‐Zentren auf Ag(100), die eine metallorganische Kette mit quasi‐eindimensionaler Metall‐Ligand‐Wechselwirkung bilden. ZUSAMMENFASSUNG Die Stabilisierung von nullwertigen Ni(0)‐Zentren in ausgedehnten Koordinationsnetzwerken bleibt aufgrund ihrer ausgeprägten Reaktivität und Anfälligkeit für ...
