Dr Qiu gave an invited presentation titled "Determining the number of threaded rings on mechanically interlocked polymers using quantitative NMR" on November 9th, 2021 at the Chicago Area NMR Discussion Group 2021 Virtual Meeting, hosted by Dr Josh Kurutz.
The collaborative work with Dr Liang Feng on mechanisorption just appeared on the Dec 3rd issue of Science.
A new mode of adsorption—mechanisorption—was reported, which results from non-equilibrium pumping to form mechanical bonds between the adsorbent and the adsorbate. This active mode of adsorption has been realized on surfaces of metal-organic frameworks grafted with arrays of artificial molecular pumps. Mechanisorption extends, in a fundamental manner, the scope and potential of adsorption phenomena and offers a transformative approach to control chemistry at surfaces and interfaces.
