Development of Sub‐50 nm Core–Shell Silica Nanoparticles With Controlled In Vivo Behavior for 19F Magnetic Resonance Imaging

Angewandte Chemie, EarlyView.
Ultrasmall PFCE‐loaded silica nanoparticles synthesized through a one‐pot double‐emulsion synthesis method, where rapid silica shell formation kinetically fixes droplet size. The resulting s‐FLAME nanoparticles enable strong 19F MRI signals with enhanced hepatic clearance rate and tumor‐accumulation performance. ABSTRACT 19F magnetic resonance imaging (

Orbital and Electrical Dual Function of Polymer Intercalant for Promoting NH4+ Storage in Vanadium Oxide Anode

Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
The impact of polyaniline insertion on the atomic orbitals and electronic structure of vanadium oxide anode is systematically investigated for the first time. The electrode exhibits an outstanding capacity and unprecedent long‐term cycling life, owing to the electron transition to the V 3dxy state and the enhanced diffusion kinetics.

A Lipid‐Conjugation Strategy for Intracellular Reactive Oxygen Species Control in Hepatic Cells

Angewandte Chemie, EarlyView.
A lipid conjugation strategy anchors a manganese Salen complex within phospholipid membranes, yielding stable, catalytically active liposomes. These lipid–metal assemblies efficiently degrade reactive oxygen species (ROS) and enable intracellular redox control in steatotic HepaRG cells, offering a precise route to biomimetic antioxidant design ...

Enhanced Formation of Dicarboxylic Acids in the Catalytic Oxidation of Polyethylene With O2 and NOx

Angewandte Chemie, EarlyView.
The oxidation of polyethylene in the presence of a mixture of O2 and NOx and with Cu2+/V5+ as catalyst yields ∼51 mol% diacids, while retaining ∼80 mol% of the carbon in the oil fraction. The developed method is robust and tolerates several polymer types as well as impurities.

Numerical modeling of lean hydrogen spark-ignition engines: On the role of intrinsic instabilities

Applications in Energy and Combustion Science
Hydrogen-fueled internal combustion engines (H2-ICEs) hold strong potential as a pathway toward CO2-neutral propulsion. To reduce Image 1001 emissions, H2-ICEs are usually operated under fuel-lean conditions, where the flames are prone to thermo ...

Novel Non‐Cytotoxic Acylphosphinates and Acylphosphine Oxides Photoinitiators

Angewandte Chemie, EarlyView.
Novel acylphosphine oxide (APO) and acylphosphinate photoinitiators based on DPO and DOPO were designed to investigate structure–property relationships including photochemical performance, polymerization efficiency and cytotoxicity. While DPO derivatives showed excellent reactivity, DOPO‐based systems also displayed good efficiency and significantly ...
