Our breakthrough on surface-charged graphene oxide membrane has been published in Nature Communications

Published:

2019-05-06

By:

Recently, PhD candidate Mengchen Zhang has published a new paper “Controllable ion transport by surface-charged graphene oxide membrane” in Nature Communications (https://doi.org/10.1038/s41467-019-09286-8), representing a further step towards graphene-based membrane. This work demonstrates a methodology for manipulation of surface charge to realize controllable ion transport through a graphene oxide membrane, in which desirable electrostatic interactions with charged ions are finely tailored to achieve remarkable enhancement of typical AB2 or A2B type salt rejections. This approach of tuning surface charges to control ion transport establishes a platform that could be of interest in a variety of applications such as water transport, studies of biomimetic ion channels and biosensors, ion batteries and energy conversions.

Big News! Congratulations! Professor Wanqin Jin was granted the Humboldt Research Award by the Alexander von Humboldt Foundation(Prof. Wanqin Jin won the 2021 Humboldt Research Prize)

The Humboldt Research Awards have been a central pillar of the Alexander von Humboldt Foundation’s sponsorship activities since 1972. The awards honor the global outstanding scientists outside Germany whose fundamental discoveries, new theories or findings have had a lasting effect on their discipline beyond their immediate research area and who are expected, moreover, to continue producing outstanding research in the future; Also, the nominee’s academic achievements must be internationally recognized and proven by corresponding successes in research. The Humboldt Research Award is the highest honor awarded to foreign scholars by the Alexander von Humboldt Foundation. It aims to commend the winners’ lifelong academic achievements and has a high international reputation. So far, a not insignificant number of award winner has subsequently been granted the Nobel Prize.

Congratulations: Dr. Zhang Mengchen's graduation thesis "Design and Preparation of Graphene oxide nanofiltration Membrane" was awarded "Excellent Doctoral Dissertation of Jiangsu Province in 2020"!

In his dissertation Design and Preparation of GO nanofiltration membrane, Dr. Zhang Mengchen proposed a new construction strategy of high performance GO nanofiltration membrane and developed the design and preparation technology of GO nanofiltration membrane, aiming at the bottleneck problems commonly faced by GO nanofiltration membrane, such as poor stability, low water permeability and low salt retention rate. The application in the separation of small organic molecules and salt ions is expanded, which provides a theoretical reference and promotion for the design and development of high performance GO nanofiltration membranes. This thesis was awarded "Excellent Doctoral Dissertation of Jiangsu Province in 2020" by Jiangsu Provincial Academic Degree Committee in December 2020 (Advisor: Jin Wanqin). Congratulations to Dr. Zhang Mengchen!
