- Blue Liquid Lasers from Solution of CdZnS/ZnS Ternary Alloy Quantum Dots with Quasi-Continuous Pumping

Blue (∼440 nm) liquid laser with an ultra-low threshold that quasi-continuous wave pumping is accessible is achieved by engineering unconventional ternary CdZnS/ZnS alloyed-core/shell QDs. Such an achievement is enabled by exploiting the novel gain media with minimal defects, suppressed Auger recombination, and large gain cross-section in combination with the high quality-factor whispering gallery mode resonators.

The controlled movement of a chemical container by the light-activated expulsion of a chemical fuel, named here “photo-chemopropulsion”, is an exciting new development in the array of mechanisms employed for controlling the movement of microvehicles, herein represented by lipid-based microdroplets. This “chemopropulsion” effect can be switched on and off, and is fully reversible.
- Supramolecular Polymers as Surface Coatings: Rapid Fabrication of Healable Superhydrophobic and Slippery Surfaces
Qiang Wei, Christoph Schlaich, Sylvain Prévost, Andrea Schulz, Christoph Böttcher, Michael Gradzielski, Zhenhui Qi, Rainer Haag and Christoph A. Schalley
Article first published online: 18 SEP 2014 | DOI: 10.1002/adma.201401366
Supramolecular polymerization for non-wetting surface coatings is described. The self-assembly of low-molecular-weight gelators (LMWGs) with perfluorinated side chains can be utilized to rapidly construct superhydrophobic as well as liquid-infused slippery surfaces within minutes. The lubricated slippery surface exhibits impressive repellency to biological liquids, such as human serum and blood, and very fast self-healing.
- Ionic Liquid Enabled FeS2 for High Energy-Density Lithium-Ion Batteries
Tyler Evans, Daniela Molina Piper, Seul Cham Kim, Sang Sub Han, Vinay Bhat, Kyu Hwan Oh and Se-Hee Lee
Article first published online: 18 SEP 2014 | DOI: 10.1002/adma.201402103
High energy density FeS2cathodes enabled by a bis(trifluoromethanesulfonyl)imide (TFSI−) anion-based room temperature ionic liquid (RTIL) electrolyte are demonstrated. A TFSI-based ionic liquid (IL) significantly mitigates the polysulfide dissolution, and therefore the parasitic redox shuttle mechanism, that plagues sulfur based electrode chemistries. FeS2 stabilization with a TFSI−-based IL results in one of the highest energy density cathodes, 542 Wh kg−1 (normalized to cathode composite mass), reported to date.
- X-ray Photon Correlation Spectroscopy Studies of Surfaces and Thin Films
Sunil K. Sinha, Zhang Jiang and Laurence B. Lurio
Article first published online: 18 SEP 2014 | DOI: 10.1002/adma.201401094
X-ray Photon Correlation Spectroscopy (XPCS) using coherent beams of X-rays to study the dynamical fluctuations of surfaces and interfaces is reviewed. The XPCS technique is described, together with applications to liquid surfaces, polymeric, surfactant and liquid crystalline films, reconfigurations of metallic surfaces, domain fluctuations in magnetic films, and non-equilibrium phenomena.
