Influence of Rim Seal Purge Flow on the Performance of an Endwall-Profiled Axial Turbine [PDF]
, 2010 Nonaxisymmetric endwall profiling is a promising method to reduce secondary losses in axial turbines. However, in high-pressure turbines, a small amount of air is ejected at the hub rim seal to prevent the ingestion of hot gases into the cavity between ...

Limnology and Oceanography: Methods, EarlyView.Abstract Accurate direct measurements of coccolithophore particulate inorganic and organic carbon ratios (PIC/POC) are crucial for understanding the physiology and role these microbes play in global ocean carbon flux. Direct measurements of POC are commonly obtained by acid fuming or applying acid directly to filters to dissolve PIC (CaCO3) prior to CN

Engineering Photonic Pigments From Titania–Block Copolymer Composites
Macromolecular Rapid Communications, EarlyView.Ligand‐functionalized TiO2 nanoparticles selectively partition into P2VP‐rich lamellae of onion‐like PS‐b‐P2VP microspheres, increasing refractive index contrast while preserving concentric order through controlled self‐assembly. The resulting dry photonic pigments display defined Bragg reflections and angle‐robust structural color.
