Measurement techniques for spray characteristics.

open access: yesJournal of the Fuel Society of Japan, 1991
Studies on the techniques of measuring spray characteristics are essential for the research on liquid atomization. The spray characteristics are classified into three larger groups; atomizing mode, droplet sizes and spatial distribution of droplets. This report describes the techniques of measuring these characteristics.First, high-speed photographing ...

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

open access: yesAdvanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.
