Sustainable rosin acid ester as internal electron donors in Ziegler-Natta catalysts for synthesis of isotactic polypropylene with high melt flow rate
Bio-derived rosin acid esters internal electron donors Ziegler-Natta catalyst polypropylene polymerization
2023/12/11
In this contribution, novel bio-derived rosin acid ester compounds have been developed and used as internal electron donors to prepare MgCl2?supported titanium catalysts for propylene polymerization. ...
A highly proton-conductive and vanadium-rejected long-side-chain sulfonated polybenzimidazole membrane for redox flow battery
Sulfonated long side chain Polybenzimidazole Vanadium redox flow battery 1 3-Propanesultone
2023/6/19
A long-side-chain sulfonated polybenzimidazole (PBI-PS) membrane was successfully prepared by the reaction of PBI with 1, 3-propanesultone for improving the efficiencies of vanadium redox flow battery...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Energy-preserving Mixed Finite Element Methods for a Ferrofluid Flow Model
铁磁流体 流动模型 节能混合 有限元方法
2023/4/27
We develop a class of mixed finite element methods for the ferrofluid flow model proposed by Shliomis [Soviet Physics JETP, 1972]. We show that the energy stability of the weak solutions to the model ...

Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Dynamics near a shear flow with Coriolis force
科里奥利力 剪切流 动力学
2023/5/16
In this talk, I will discuss the dynamics near a shear flow when the Coriolis force is involved. Compared with the non-Coriolis case, the spectral properties of the linearized Euler operator change fu...
MIT chemists develop a wireless electronic lateral flow assay test for biosensing（图）
生物传感 无线电子 侧流测定
2023/6/7
Lateral flow assays (LFA) tests have become ubiquitous within the general public; they are the format for standard home pregnancy and Covid-19 tests, indicating a positive result with a colored line, ...
The latest research from the labs of Penn scientists Paulo Arratia and Douglas Jerolmack was an answer to “a call for help,” says Arratia.
