Turning Microstructure in Block Copolymer Membranes: A Facile Strategy to Improve CO2 Separation Performance

open access: yesAdvanced Science, EarlyView.
A simple and effective non‐solvent‐induced microstructure rearrangement (MSR) technique is proposed to enhance the gas separation performance of Pebax 2533 membranes. By immersing Pebax 2533 membranes in amino acid salt solutions to induce MSR, the CO2 permeability of the Pebax 2533‐GlyK 10 wt.% membrane reached 1180 Barrer.

Cu7S4 Nanozyme Efficiently Inactivating Drug‐Resistant Bacteria on Mouse Wound Models through Photodynamic and Photothermal Synergetic Therapy

open access: yesAdvanced Science, EarlyView.
Cu7S4 nanozymes, exhibiting peroxidase‐like, catalase‐like, and GSH‐depletion activities, are synthesized through defect engineering. These nanozymes demonstrate rapid inactivation of Gram‐negative bacteria, including Escherichia coli and Pseudomonas aeruginosa. In a mouse skin wound model infected with P. aeruginosa, the nanozyme showcases exceptional

Efficient quantum state tomography with auxiliary Hilbert space [PDF]

open access: yesarXiv, 2019
Quantum state tomography is an important tool for quantum communication, computation, metrology, and simulation. Efficient quantum state tomography on a high dimensional quantum system is still a challenging problem. Here, we propose a novel quantum state tomography method, auxiliary Hilbert space tomography, to avoid pre-rotations before measurement ...
