Atom‐Efficient Cerium‐Based Molecular Cages as Biocompatible Reactive Oxygen Scavengers

Advanced Healthcare Materials, EarlyView.
Discrete mixed‐valent cerium molecular cages organize accessible redox centers within confined coordination environments and scavenge superoxide, hydrogen peroxide, and hydroxyl radicals. Encapsulation of the lead cage in an ROS‐responsive DTP nanoplatform enables lesion‐associated delivery, attenuates macrophage oxidative stress and inflammation, and ...

Investigation on an experimental approach to evaluate a wear model for hydrodynamic cylindrical bearings

, 2020
This work aims to investigate and identify the wear parameters in cylindrical hydrodynamic bearings, an inherent problem due to repeated use of rotating machinery, accentuated in starts/stops or during the crossover of resonance.

Hemocompatible Glycogen‐Tissue Plasminogen Activator Complexes for Enhanced Blood Clot Dissolution

Advanced Healthcare Materials, EarlyView.
Glycogen–heparin‐cRGD nanoparticles enable targeted delivery of tissue plasminogen activator (tPA) to thrombi through activated platelet recognition. The hemocompatible hybrids minimize interactions with blood and immune cells while retaining enzymatic biodegradability.

Investigation of the Impact of Ducted Propellers on AUV Hydrodynamic Performance Based on CFD

Kongzhi Yu Xinxi Jishu, 2023
Autonomous underwater vehicle (AUV) equipped with ducted propellers exhibit increased maneuverability. However, ducting also influences the AUV's dynamic characteristics. Accordingly, it is crucial to analyze the effect that ducted propellers exert on an

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

Advanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

A hydrodynamic-ecological model for Lake Rerewhakaaitu

, 2015
Lake Rerewhakaaitu is a shallow (average depth 7m, maximum depth: 15m) lake in the Rotorua region and is unique amongst the 12 Rotorua Lakes in that its catchment is the only one dominated by dairy farming as the main type of land use.

A mathematical model for radiation hydrodynamics

Le Matematiche, 1990
Summary: We adopt here the idea of describing a radiation field by means of the radiation energy density \(E\) and the radiative flux vector \(F\) which must satisfy a set of evolution equations; in these equations an unknown tensorial function \(P(E,F)\) appears that is determined by the methods of extended thermodynamics.

Differential Sedimentation and Cryo‐TEM Mapping Resolve Structural Heterogeneity in Conjugated Polymer Nanowires for Programmable Stretchable Electronics

Advanced Materials, EarlyView.
Density‐driven differential sedimentation fractionates solution‐assembled P3HT nanowires into crystalline and disordered constituents. High‐resolution cryo‐TEM directly visualizes the molecular chain packing within individual nanowires in real space, and recombining the fractions programs the mobility–stretchability trade‐off without chemical ...
