Julian Gröbner, Guest editor and chairman of the NEWRAD scientific committee Physikalisch-Meteorologisches Observatorium Davos, World Radiation Center (PMOD/WRC) Dorfstrasse 33 7260 Davos Dorf, Switzerland The 14th International Conference on New Developments and Applications in Optical Radiometry (NEWRAD 2021) was organised by the National Institute for Standards and Technology (NIST), Boulder, United States and held online from 21 to 24 June 2021. Due to the COVID pandemic the original venue at Boulder in June 2020 had to be postponed and changed to a virtual event with a novel schedule consisting of pre-recorded talks and live sessions with the presenters to interact with conference attendees. The event was very well attended, notwithstanding the global participation with corresponding challenging time zones of the participants. A total of 274 registrations were received, with typically more than 100 attendees joining the online sessions. The NEWRAD scientific Committee would like to thank John Lehman and the whole local organising team for organising and holding this excellent event in the frame of these challenging conditions. 142 presentations were submitted, of which 48 were selected for oral talks, while the remaining submissions were presented as posters.

Dose Imaging

Heterogeneous catalysts can be of varying complexity ranging from single or double phase systems to complicated mixtures of metals and oxides with additives to help promote chemical reactions, extend the life of the catalysts, prevent poisoning etc. Although catalysis occurs on the surface of most systems, detailed descriptions of the microstructure and chemistry of catalysts can be helpful for developing an understanding of the mechanism by which a catalyst facilitates a reaction. Recent years have seen continued development and improvement of various TEM, STEM and AEM techniques for yielding information on the structure and chemistry of catalysts on the nanometer scale. Here we review some quantitative approaches to catalyst characterization that have resulted from new developments in instrumentation.HREM has been used to examine structural features of catalysts often by employing profile imaging techniques to study atomic details on the surface. Digital recording techniques employing slow-scan CCD cameras have facilitated the use of low-dose imaging in zeolite structure analysis and electron crystallography. Fig. la shows a low-dose image from SSZ-33 zeolite revealing the presence of a stacking fault.

And Function

Despite advances in surgical management, it is estimated that 20–30% of children with repaired cleft palate will continue to have hypernasal speech and require a second surgery to create normal velopharyngeal function (Bricknell, McFadden, & Curran, 2002; Härtel, Karsten, & Gundlach, 1994; McWilliams, 1990). A qualitative perceptual assessment by a speech-language pathologist is considered the most important step of the evaluation for children with resonance disorders (Peterson-Falzone, Hardin-Jones, & Karnell, 2010). Direct and indirect instrumental analyses should be used to confirm or validate the perceptual evaluation of an experienced speech-language pathologist (Paal, Reulbach, Strobel-Schwarthoff, Nkenke, & Schuster, 2005). The purpose of this article is to provide an overview of current instrumental assessment methods used in cleft palate care. Both direct and indirect instrumental procedures will be reviewed with descriptions of the advantages and disadvantages of each. Lastly, new developments for evaluating velopharyngeal structures and function will be provided.
