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

open access: yesAdvanced 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.

An experimental study of the transfer function of a ducted, laminar premixed flame

open access: yes, 2012
This paper presents an experimental study of the transfer function of a ducted, laminar, premixed flame. This transfer function is defined as the ratio of the fluctuations in flame heat release to the flow velocity modulations at the base of the flame. A

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

open access: yesAngewandte 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 ...

Intrinsic thermo-acoustic instability criteria based on frequency response of flame transfer function

open access: yes, 2022
A study of Intrinsic Thermo-Acoustic (ITA) instability behavior of flames anchored to a burner deck is performed by introducing a mapping between the Flame Transfer Function, FTF(s), defined in the complex (Laplace) domain and the experimentally measured

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

open access: yesAngewandte 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.
