In order to reflect on the lack of developing content knowledge of technology education in Taiwan's primary teacher education, the main aim of this study was to develop a STEM-based game-design project for helping preservice primary teachers acquire computational...

Wedge and gap plasmonic resonances in double nanoholes.

Optics express

Chen Y, Kotnala A, Yu L, Zhang J, Gordon R.
PMID: 26698503
Opt Express. 2015 Nov 16;23(23):30227-36. doi: 10.1364/OE.23.030227.

We study the plasmonic resonances of double nanoholes (DNHs) in metal films. These apertures exhibit the usual gap-mode Fabry-Pérot resonances, where the zeroth order resonance is determined by the waveguide cut-off and the first order resonance shows sensitivity to...

Effect of non-acoustic parameters on heterogeneous sonoporation mediated by single-pulse ultrasound and microbubbles.

Ultrasonics sonochemistry

Qin P, Xu L, Han T, Du L, Yu AC.
PMID: 26964929
Ultrason Sonochem. 2016 Jul;31:107-15. doi: 10.1016/j.ultsonch.2015.12.001. Epub 2015 Dec 09.

Sonoporation-transient plasma membrane perforation elicited by the interaction of ultrasound waves with microbubbles--has shown great potential for drug delivery and gene therapy. However, the heterogeneity of sonoporation introduces complexities and challenges in the realization of controllable and predictable drug...

Bio-inspired Murray materials for mass transfer and activity.

Nature communications

Zheng X, Shen G, Wang C, Li Y, Dunphy D, Hasan T, Brinker CJ, Su BL.
PMID: 28382972
Nat Commun. 2017 Apr 06;8:14921. doi: 10.1038/ncomms14921.

Both plants and animals possess analogous tissues containing hierarchical networks of pores, with pore size ratios that have evolved to maximize mass transport and rates of reactions. The underlying physical principles of this optimized hierarchical design are embodied in...

Reversible Photoresponsive Molecular Alignment of Liquid Crystals at Fluid Interfaces with Persistent Stability.

Chemistry (Weinheim an der Bergstrasse, Germany)

Tian T, Hu Q, Wang Y, Gao Y, Yu L.
PMID: 27004449
Chemistry. 2016 Apr 25;22(18):6340-4. doi: 10.1002/chem.201600095. Epub 2016 Mar 23.

This work demonstrates a noninvasive approach to control alignment of liquid crystals persistently and reversibly at fluid interfaces by using a photoresponsive azobenzene-based surfactant dissolved in an ionic liquid (IL), ethylammonium nitrate (EAN). As the first report on the...

Multisensor-Based Periodic Estimation in Sensor Networks With Transmission Constraint and Periodic Mixed Storage.

IEEE transactions on cybernetics

Song H, Zhang WA, Yu L, Chen B.
PMID: 27705872
IEEE Trans Cybern. 2017 Dec;47(12):4367-4379. doi: 10.1109/TCYB.2016.2609503. Epub 2016 Sep 29.

In this paper, we consider a periodic estimation problem in sensor networks with a shared communication channel. The transmission constraint is inevitable in a single-channel-based sensor network if the sensors are heterogeneous or deployed far away from each other....
