Further commissioning activities and initial user science took place in June at bend-magnet station F3. General user science with the Maia detector began in earnest in October, in conjunction with a 48-hour workshop on the Maia detector and the software analysis package GeoPIXE. Twelve workshop attendees from eight unique user groups spent a day and a half reviewing critical XRF concepts and gaining hands-on experience with data analysis, accessing GeoPIXE on the central compute farm via their own PCs.

To understand this critical cellular process, biologists are studying the fine details of the structural changes involved, and how they are regulated. RNAP complexes vary from one species to another, but a core subset of proteins is found throughout archaeal and eukaryotic life forms. Comparison of archaeal and eukaryotic proteins reveals how structural motifs have been modified during evolution, so that function is maintained while regulation has become more complex in eukaryotic species.

Staff scientist Detlef Smilgies arranged an opportunity for graduate students in the D1 group to mentor students in the Cornell School of Material Science and Engineering. Professor Chekesha Liddell Watson of the Cornell Department of Materials Science and Engineering offered a course on the instruments and commonly used analytical methods encountered in the fields of physics and material sciences as part of the undergrad senior curriculum.

OVERVIEWS AND AIMS

What did the scientists discover?

Non-wovens usually experience damage under external loading. Hence, a good understanding of damage mechanisms is of great value in designing new non-woven materials.

What did the Scientists Discover?

TeraPore develops and manufactures filters with unprecedented performance through a proprietary and scalable block copolymer self-assembly technology. When fabricated into membranes, the polymers spontaneously form into highly uniform structures, creating precise holes (or pores) on the nanoscale. The benefits of these membranes include high permeability, allowing very high flow rates, and uniform pore sizes for highly precise nanofiltration.

The multidisciplinary team, led by Tobias Hanrath, associate professor in the Robert Frederick Smith School of Chemical and Biomolecular Engineering, and graduate student Kevin Whitham, has fashioned two-dimensional superstructures out of single-crystal building blocks. Through directed assembly and attachment processes, the lead selenide quantum dots are synthesized into larger crystals, then fused together to form atomically coherent square superlattices.

The school averages 320 children per year, 66% of whom, in 2014, receive free lunch, and 4% more receive reduced lunch. This large percentage of the school population is less likely to have: family backgrounds in the sciences and engineering, general background information to apply to solving problems in society, early school readiness skills for developing an inquiry focus, exposure to role models and innovators, and other privileged access to exploring the world at large.

Previous studies have shown the inhibitory properties of sweeteners, such as saccharin, to CA IX. In this study, the binding of the sweetener acesulfame potassium (Ace K) is compared between CA IX and other essential carbonic anhydrases in the body.
