Molecular-level petroleum refining by graded membranes

Yuecheng Wang, F.Q. Dong, Yujie Ban, Ziyi Hu et autres

Abstract Light naphtha is a critical feedstock whose full value relies on molecular-level fractionation into value-specific streams. Achieving such precise separation remains difficult because its components exhibit extremely similar physicochemical properties. Here, we address this challenge by developing a graded membrane cascade …

Numerical investigation of the effect of side-hole geometry on shear stress distribution and blood damage in drainage cannula during venovenous extracorporeal membrane oxygenation

Jing-Lin Ge, Yongjiang Li, Xiao‐Ming Chen, Dong Chen et autres

Venovenous extracorporeal membrane oxygenation is a critical life support technique for patients with severe respiratory failure refractory to conventional therapy. Special attention should be paid to the design of drainage cannulas because, unlike return cannulas, they generally have multiple side holes to …

Fe metal–organic framework–derived heterojunction for metabolic diagnosis of thymic epithelial tumor

Yongpeng Liang, Haochen Han, Y. Zhao, Wenjun Yu et autres

Thymic epithelial tumors (TETs), rare yet clinically significant malignancies, face diagnostic challenges due to their occult presentation and lack of noninvasive risk-stratification tools, leading to systemic overtreatment and poor prognoses for high-risk subtypes. To address this unmet need, we developed a Fe …

Basic Aluminum Benzoate is Low-Cost, Porous, and Superhydrophobic

Zhi‐Shuo Wang, Mu‐Yang Zhou, Ding-Yi Hu, Xiaoxian Chen et autres

Superhydrophobic materials are of tremendous application prospects, but they typically need to be prepared by relatively expensive reagents or complex treatments. Here, we report a simple aluminum-based coordination polymer [Al(OH)(ba) 2 ] (MCF-66, Hba = benzoic acid), which can be facilely synthesized …

Vitrification and Cold Crystallization of a One-Dimensional Perovskite-like Compound Enabled by Reorganizable Coordination Bonds and a Configurationally Restricted Cation

Zi‐Yi Du, Miao Xie, Weiyu Hu, Qing Wang et autres

Understanding glass formation and transformation remains a fundamental challenge in materials science. Here, we report the first example of vitrification and multifactor-triggered cold crystallization in a one-dimensional (1D) perovskite-like coordination polymer, (4-methylmorpholinium)[Cd(SCN) 3 ]. By introducing cleavable and reorganizable Cd–S/N coordination bonds, …
