Regeneration‐Optimized Chemisorbents: Evaluating Hybrid Coordination Networks for Atmospheric Water Harvesting

open access: yesAngewandte Chemie, EarlyView.
Atmospheric water harvesting (AWH) under arid conditions requires desiccants that load water below 30% RH and regenerate below 60°C, a performance regime traditionally limited to physisorbents. Here, we show that the inherent hydrolytic instability of M′FSIX‐25‐M coordination networks enable regeneration‐optimized chemisorbents (ROCs) with projected ...

A Neutrophil Membrane‐Encapsulated Pd/hCeO2 Nanoformulation for Alleviating Age‐Dependent Perioperative Neurocognitive Disorders

open access: yesAdvanced Science, EarlyView.
This study reports a neutrophil membrane‐encapsulated Pd/hCeO2 nanozyme (PCN) for targeted treatment of perioperative neurocognitive disorders (PND) in aged mice. PCN inhibits glycolysis‐driven microglial activation and neuroinflammation, improves mitochondrial respiration, and maintains blood‐brain barrier integrity and synaptic function, ultimately ...

Cystic Pancreatic Lesions Beyond the Guidelines: Can we Make an Evidence-Based Decision Whether to Resect or to Observe? [PDF]

open access: yesEuropean Medical Journal Gastroenterology, 2015
Pancreatic cystic neoplasms (PCNs) are no longer considered as rare entities because their prevalence in the general population ranges from 3–20%. They are usually asymptomatic, incidentally discovered, and diagnosed in the seventh decade of life.

Polyphosphate Copper Nanospheres Drive Mitochondrial Metabolic Reprogramming via Calcium Phase Separation for Self‐Sensitizing Cuproptosis

open access: yesAdvanced Science, EarlyView.
This study developed polyphosphate (polyP)‐based nanostructures that enable calcium‐mediated metabolic reprogramming via liquid–liquid phase separation (LLPS). Released polyP undergoes LLPS with Ca2+, suppressing glycolytic flux and enhancing mitochondrial metabolism effectively.
