The winners for the 2017 WITec Paper Award have been announced. From nearly 60 submissions, the jury selected the top three publications from Ireland, Portugal and Germany: they show in remarkable detail how information on the chemical and structural composition of a material, obtained through this non-destructive technique, can lead to a more comprehensive understanding of a wide range of materials. They used WITec correlative confocal Raman microscopes to study transition metal dichalcogenides, textile fibers and cement. 

Winning Publications of the 2017 WITec Paper Award:

Gold: Mapping of low-frequency Raman modes in CVD-grown transition metal dichalcogenides: layer number, stacking orientation and resonant effects. Scientific Reports 2016, 6, 19476. DOI:10.1038/srep19476.

Silver: SERS and Raman imaging as a new tool to monitor dyeing on textile fibres. Journal of Raman Spectroscopy 2016, 47, 1239. DOI:10.1002/jrs.4947

Bronze: Confocal Raman microscopy as a non-destructive tool to study microstructure of hydrating cementitious materials. Cement and Concrete Research 2016, 88, 136. DOI:10.106/j.cemconres.2016.07.005.

The Gold Paper Award is conferred upon Maria O’Brien from Trinity College in Dublin (Ireland) for mapping low-frequency Raman modes of four transition metal dichalcogenides (TMDCs): MoS2, MoSe2, WS2 and WSe2. Together with Niall McEvoy, Damien Hanlon, Toby Hallam, Jonathan Coleman and Georg Duesberg, she used the Raman modes for in-plane and out-of-plane vibrations whose intensities depend on the thickness and the stacking order of the molecules’ layers. The study has shown that the low-frequency Raman modes of these materials reveal additional information compared to conventional Raman modes.

The Silver Paper Award is given to Helena Nogueira from the University of Aveiro (Portugal). She and her co-authors Sara Fateixa, Manon Wilhelm and Tito Trindade used three-dimensional Raman imaging and surface enhanced Raman scattering (SERS) to monitor the dyeing process of linen textile fibers with methylene blue.

This dye is most commonly used for blue coloring and was applied by various procedures. The scientists also visualized how the silver nanoparticles that give textiles antimicrobial properties are distributed along and within the linen fibers. The authors conclude that regarding textile production “… Raman imaging and SERS are valuable assets that complement or eventually provide unique characterization data.”

The Bronze Paper Award goes to Jonas Higl from the University of Ulm (Germany) for a Raman study on hydrating of cementitious materials. With his colleagues Marcus Köhler and Mika Lindén, he used confocal Raman microscopy to document which structures and molecules are formed during the complex process of hydrating C3S clinker. To the knowledge of the authors this study was the first one published using Raman imaging to study hydrating of cement.

The annual awards recognize outstanding scientific work published the preceding year that employed a WITec device as part of its experimental setup. The evaluation criteria include the significance of the results for the scientific community and the originality of the techniques used.

Paper Award 2018
WITec recently announced the 2018 WITec Paper Award competition for research articles published in 2017. Scientists from all fields of application in both academia and industry are invited to submit their publications featuring results acquired with a WITec instrument to papers@witec.de. The deadline for submissions is January 31st, 2018.
