Monolayer Studies of Mixed Films Containing Cerebrosides by Surface Tensiometry and Brewster Angle Microscopy
… films resulted in line-shaped 2-D and 3-D structures. Introduction of cholesterol into bovine cerebrosides monolayers resulted in more loosely packed domains. A similar trend was observed upon the addition of PA to porcine cerebrosides. Surface morphology, collapse pressures, and collapse …

Interfacial physics in meniscus-confined electrodeposition and its applications for fabricating electronic structures
… to direct-write pure metallic three-dimensional structures of designed shapes and sizes in an ambient air environment. This technique is cost-effective to implement and is based on the principle of electrodeposition, and can thus be applied to fabricate structures made of a wide variety of …

Computational approaches to modeling the conserved structural core among distantly homologous proteins
… to classify and annotate proteins with structures that are unknown, but similar to solved structures. The first algorithm is actually a tool for better understanding solved structures themselves. Namely, we introduce the multiple alignment algorithm Matt (Multiple Alignment with …

Evaluation and Application of Max-DOAS Methods for Monitoring Aerosols, NO2, and SO2 in Urban and Industrial Environments
… using MAX-DOAS confirms previously theorized 3-D structures of lake breezes. Finally, the mobile-MAX-DOAS technique of estimating NOx and SO2 emissions was improved by conducting simultaneous Mobile-MAX-DOAS and in-situ NO-NO2-NOx measurements and deploying a modular meteorological station while …

Investigating the Structure of the Papain-Inhibitor Complex using SPR and NMR
… Leishmania mexicana. Although the individual 3-D structures of ICP and papain have been determined, as of this work, the structure of the papain-ICP complex has only been predicted, not solved. This research details the development of a technique for determining quaternary structure of the …
