Research Lab Manager, Dr Han Wu publishes 2 new papers

25 November 2019

Dr Han Wu whom is currently managing the Research Facility for the Department of Chemical Engineering has published 2 papers in the span of 1 month both on the use of the Ganesha 300XL SAXS (SAXSLAB) instrument available in the Centre for Nature inspired Engineering facility.

The first paper was published in the reputed Journal of Colloid and Interface Science, titled "Self-assembled micro-stripe patterning of sessile polymeric nano-fluid droplets". The paper was made in collaboration with UCL Mechanical Engineering PhD student Xinyue Jennifer Jiang and other collaborators from Hacettepe University. Han quotes "We measured self-assembled nano-droplet (size~100nm) both in liquid- and solid-state, and compared to DLS analysis for complete particle size characterisation. The larger size detected by DLS is likely caused by continuous growth in solution which is a common phenomenon. Advantage of SAXS Direct measurement of solid self-assembled particles formed on glass slide in its 'native' state eliminates the solvent effect and additional dilution process."

The second paper was made in collaboration with the MIcroFluidics research groups in the UCL Chemical Engineering Department lead by Prof. Asterios Gavriilidis. It was titled "Rapid synthesis of [Au25(Cys)18] nano-clusters via carbon monoxide in microfluidic liquid-liquid segmented flow system and their antimicrobial performance" and published in the prestigious Chemical Engineering Journal. She quotes "The quick determination of particle size of AuNPs at 1.5nm-means a big step for us and future applications"
