PMID: 27008347
Adv Mater. 2016 May;28(19):3683-9. doi: 10.1002/adma.201600069. Epub 2016 Mar 23.

Heterostructured photoconductors based on hybrid perovskites and 2D transition-metal dichalcogenides are fabricated and characterized. Due to the superior properties of CH3 NH3 PbI3 and WS2 , as well as the efficient interfacial charge transfer, such photoconductors show high performance...

Spectrum gaps of spin waves generated by interference in a uniform nanostripe waveguide.

Scientific reports

Wang Q, Zhang H, Ma G, Liao Y, Tang X, Zhong Z.
PMID: 25082001
Sci Rep. 2014 Aug 01;4:5917. doi: 10.1038/srep05917.

We studied spin waves excited by two or more excitation sources in a uniform nanostripe waveguide without periodic structures. Several distinct spectrum gaps formed by spin waves interference rather than by Bragg reflection were observed. We found the center...

Visualizing oil displacement with foam in a microfluidic device with permeability contrast.

Lab on a chip

Conn CA, Ma K, Hirasaki GJ, Biswal SL.
PMID: 25112724
Lab Chip. 2014 Oct 21;14(20):3968-77. doi: 10.1039/c4lc00620h.

Foam mobility control and novel oil displacement mechanisms were observed in a microfluidic device representing a porous media system with layered permeability. Foam was pre-generated using a flow-focusing microfluidic device and injected into an oil-wet, oil-saturated 2-D PDMS microfluidic...

Solution-Grown Monocrystalline Hybrid Perovskite Films for Hole-Transporter-Free Solar Cells.

Adv Mater. 2016 May;28(17):3383-90. doi: 10.1002/adma.201506292. Epub 2016 Mar 02.

High-quality perovskite monocrystalline films are successfully grown through cavitation-triggered asymmetric crystallization. These films enable a simple cell structure, ITO/CH3 NH3 PbBr3 /Au, with near 100% internal quantum efficiency, promising power conversion efficiencies (PCEs) >5%, and superior stability for prototype...

Angew Chem Int Ed Engl. 2017 Jun 26;56(27):7847-7852. doi: 10.1002/anie.201703720. Epub 2017 Jun 01.

Herein we introduce a straightforward, low cost, scalable, and technologically relevant method to manufacture an all-carbon, electroactive, nitrogen-doped nanoporous-carbon/carbon-nanotube composite membrane, dubbed "HNCM/CNT". The membrane is demonstrated to function as a binder-free, high-performance gas diffusion electrode for the electrocatalytic...
