Fine‐Tuned Magnetic and Electrochemical Properties of a Series of Fe(II) Complexes with Asymmetric Jäger‐Type (N2O2)2− Ligands

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 1, January 6, 2026.
Asymmetrically substituted Jäger‐type ligands and their Fe(II) complexes show additive optical and redox trends. Ketone donors promote spin‐crossover while ester donors stabilize the high‐spin state, yet bulk materials display unexpected transitions governed by molecular symmetry and packing. A series of seven new asymmetrically substituted Jäger‐type (

Wafer‐Scale Integration of α‐quartz Thin Films toward Super High Frequency Piezoelectric bioNEMS for Chikungunya Virus Detection

Advanced Functional Materials, Volume 36, Issue 1, 2 January 2026.
Epitaxial piezoelectric α‐quartz/Si BioNEMS sensors, made using soft chemistry, effectively detect the Chikungunya virus. They have a mass sensitivity of 205 pg Hz−1 in liquid and can detect the virus at a limit of 9 ng mL−1. This development enables high‐frequency mass devices for point‐of‐care testing in healthcare and other electronic applications ...

Neutrophil Extracellular Trap Reprograms Cancer Metabolism to Form a Metastatic Niche Promoting Non‐Small Cell Lung Cancer Brain Metastasis

Advanced Science, Volume 13, Issue 5, 27 January 2026.
This study mainly combines spatial/single‐cell transcriptomics and metabolomics to reveal LOX+ Malig‐5 as NSCLC brain metastasis‐initiating cells, forming a niche with NET‐releasing neutrophils via the NET‐KRT10 axis. The metastatic niche is involved with metabolic reprogramming, with palmitic acid serving as a key metabolite.
