Advanced 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.

arXiv, 2012 This fluid dynamics video presents the gravity-driven jets induced by the relaxation of large prolate bubbles or large holes at a free liquid surface. It shows that the jet developing inside a bubble can be strong enough to give rise to liquid projections shooting out way above the free surface.

Chemical engineering, 1964 槽内にジェットを噴出させて液-液系撹拌操作を行なう場合について模型実験を行ない, 噴射角度を一定にしてノズル口径, ジェットの流速をいろいろに変えたときの撹拌効果を比較検討した。その結果, 限られた槽内にジェットを噴射して撹拌を行なう場合には, ジェットの運動量を大きくするだけでなくノズル口径およびジェットの流速を考慮する必要があることを見出した。

Kelvin-Helmholtz and Buckling Instabilities for a Viscoelastic Liquid [PDF]
arXiv, 2012 In this fluid dynamics video prepared for the APS-DFD Gallery of Fluid Motion we study the Kelvin-Helmholtz instability for both Newtonian and viscoelastic jets. The nonlinear dynamics of the jet motion are slowed down by orders of magnitude using a synchronized strobe effect coupled with precise timing control of perturbation frequencies.

Di-jet hadron pair correlation in a hydrodynamical model with a quenching jet
, 2008 In jet quenching, a hard QCD parton, before fragmenting into a jet of hadrons, deposits a fraction of its energy in the medium, leading to suppressed production of high-$p_T$ hadrons.
