Adiabatic and Nonadiabatic Charge Transport in Li–S Batteries

16-Jan-2018 | Haesun Park; Nitin Kumar; Marko Melander; Tejs Vegge; Juan Maria Garcia Lastra; Donald J. Siegel, Chemistry of Materials, 2018

The insulating nature of the redox end members in Li–S batteries, α-S and Li2S, has the potential to limit the capacity and efficiency of this emerging energy storage system. Nevertheless, the mechanisms responsible for ionic and electronic transport in these materials remain a matter of debate. ...

Solvent-Engineering Method to Deposit Compact Bismuth-Based Thin Films: Mechanism and Application to Photovoltaics

12-Jan-2018 | Seong Sik Shin; Juan Pablo Correa Baena; Rachel C. Kurchin; Alex Polizzotti; Jason Jungwan Yoo; Sarah Wieghold; Moun ..., Chemistry of Materials, 2018

Bismuth-based materials have been studied as alternatives to lead-based perovskite materials for photovoltaic applications. However, poor film quality has limited device performance. In this work, we developed a solvent-engineering method and show that it is applicable to several bismuth-based ...

Transformation of Mesostructured Silica Nanoparticles into Colloidal Hollow Nanoparticles in the Presence of a Bridged-Organosiloxane Shell

11-Jan-2018 | Eisuke Yamamoto; Saki Uchida; Atsushi Shimojima; Hiroaki Wada; Kazuyuki Kuroda, Chemistry of Materials, 2018

Hollow siloxane-based nanoparticles (HSNs) have attracted significant attention because of their unique properties and applications. Recently, it was discovered that the simple covering of silica nanoparticles with an organosiloxane shell leads to the spontaneous formation of HSNs; however, the ...

Potential Semiconducting and Superconducting Metastable Si3C Structures under Pressure

11-Jan-2018 | Guoying Gao; Xiaowei Liang; N. W. Ashcroft; Roald Hoffmann, Chemistry of Materials, 2018

Si3C is predicted to take on a diamond type structure (space group: I4̅2d), at P = 1 atm, consistent with the experimental results on a cubic Si0.75C0.25 alloy. This structure is computed to be a semiconductor with a direct band gap of about 1.3 eV, within the desired values. Under pressure, Si3C ...

Improved Stability and Performance of Visible Photoelectrochemical Water Splitting on Solution-Processed Organic Semiconductor Thin Films by Ultrathin Metal Oxide Passivation

11-Jan-2018 | Lei Wang; Danhua Yan; David W. Shaffer; Xinyi Ye; Bobby H. Layne; Javier J. Concepcion; Mingzhao Liu; Chang-Yong Nam, Chemistry of Materials, 2018

Solution-processable organic semiconductors have potentials as visible photoelectrochemical (PEC) water splitting photoelectrodes due to their tunable small band gap and electronic energy levels, but they are typically limited by poor stability and photocatalytic activity. Here, we demonstrate ...

Mesoporous Bimetallic RhCu Alloy Nanospheres Using a Sophisticated Soft-Templating Strategy

10-Jan-2018 | Bo Jiang; Kenya Kani; Muhammad Iqbal; Hideki Abe; Tatsuo Kimura; Md. Shahriar A. Hossain; Oruganti Anjaneyulu; Joel ..., Chemistry of Materials, 2018

Mesoporous metals are useful for heterogeneous catalysis because their ultrapermeable architecture promotes mass transport to abundant active sites. Our group recently developed a method to manipulate the interior space of nanocrystals by synthesizing mesoporous Rh nanospheres that serve as high ...

Mechanical Properties of Metal Oxide Aerogels

22-Dec-2017 | Albrecht Benad; Florian Jürries; Birgit Vetter; Benjamin Klemmed; René Hübner; Christoph Leyens; Alexander Eychmüller, Chemistry of Materials, 2017

In this study we report on mechanical properties of molded, single component Al2O3, Ga2O3, Fe2O3, and ZrO2 as well as mixed aerogels, made from yttrium stabilized zirconia, yttrium aluminum garnet, and zinc aluminum spinel. Initially all aerogels were produced equally in molded bodies by a facile ...

Nanoporous Polymer Networks Templated by Gemini Surfactant Lyotropic Liquid Crystals

22-Dec-2017 | James Jennings; Brian Green; Tyler J. Mann; C. Allan Guymon; Mahesh K. Mahanthappa, Chemistry of Materials, 2017

Nanoporous polymers with periodic, ordered structures have attracted significant interest for their potential applications as drug delivery vehicles, biomaterials, separations membranes, and materials for energy storage. Inducing polymer nanostructure through lyotropic liquid crystal-templated ...
