Defect-rich three-dimensionally ordered macroporous magnesium cobalt oxide spinel coupled with graphite felt for vanadium redox flow batteries

Developing electrodes that simultaneously enable rapid redox kinetics and efficient mass transport is critical for advancing high-performance vanadium redox flow batteries (VRFBs). Herein, a defect-rich three-dimensionally ordered macroporous MgCo 2 O 4 catalyst is integrated ont...

Silk Fibroin–Polyethylene Glycol 400 Composite Sponges with Enhanced Water Absorption and Hemostatic Performance

Abstract We have developed silk fibroin (SF)–polyethylene glycol (PEG) composite sponges, focusing on PEG 400 (PEG400), to enhance the mechanical strength, water absorption, and hemostatic performance of SF sponges. The SF–PEG400 sponge showed superior water absorption—approximat...

Analysis of Critical Points in a Permutation Model on Hierarchical Lattices by Real-Space Renormalization Group

The permutation model is a classical spin system where elements of the symmetric group interact with one another. The partition function of this model is directly related to the entanglement structure of random quantum circuits and random tensor networks. In these contexts, the e...

Probing Lattice‐Oxygen Redox in Pt‐WO 3 Nanocrystals by Operando Spectroscopy: Bridging Surface Chemistry and Ethanol Sensing

ABSTRACT Understanding how lattice oxygen participates in gas sensing remains a challenge in metal‐oxide chemistry. Here, we combine operando diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), operando Raman spectroscopy, ex situ electron paramagnetic resonance...
