Vertical structures induced by embedded moonlets in Saturn's rings: the gap region [PDF]

open access: yesarXiv, 2012
We study the vertical extent of propeller structures in Saturn's rings. Our focus lies on the gap region of the propeller and on non-inclined propeller moonlets. In order to describe the vertical structure of propellers we extend the model of Spahn and Sremcevic (2000) to include the vertical direction.

Enhancing UV Stability and Charge Extraction in Organic Solar Cells with Phenyl‐Linked Aromatic Self‐Assembled Monolayer

open access: yesAdvanced Functional Materials, EarlyView.
The phenyl‐linked self‐assembled monolayer exhibits robust intrinsic stability and hole extraction capability compared to the alkyl‐linked counterparts, thus facilitating the device stability with T80 over 1000 h and efficiency of 19.7% in advancing organic solar cells.

Designing of Self‐Dispersing Soft Dendritic Microcleaners for Microplastics Capture and Recovery

open access: yesAdvanced Functional Materials, EarlyView.
The capture and recovery of microplastics from open aquatic systems is a complex problem, which necessitates nontrivial solutions. The principles of a comprehensive multistage process based on sustainably sourced microcleaners with hierarchical morphology are demonstrated.

ASSESSMENT OF THE SYNTHESIS ROUTES CONDITIONS FOR OBTAINING AMMONIUM DINITRAMIDE BY THE FT-IR. DOI: 10.5028/jatm.2011.03033311

open access: yesJournal of Aerospace Technology and Management, 2012
Over the last two decades, many routes have been proposed to synthesize ammonium dinitramide (ADN). However, most of them lie in routes in which reactants are too expensive for large-scale production.
