An Anti-Fatigue Design Strategy for 3D Ribbon-Shaped Flexible Electronics.

Adv Mater 2021 Sep 2;33(37):e2102684. Epub 2021 Aug 2.

Key Laboratory of Applied Mechanics of Ministry of Education, Department of Engineering Mechanics, Tsinghua University, Beijing, 100084, P. R. China.

Three-dimensional (3D) flexible electronics represent an emerging area of intensive attention in recent years, owing to their broad-ranging applications in wearable electronics, flexible robots, tissue/cell scaffolds, among others. The widely adopted 3D conductive mesostructures in the functional device systems would inevitably undergo repetitive out-of-plane compressions during practical operations, and thus, anti-fatigue design strategies are of great significance to improve the reliability of 3D flexible electronics. Previous studies mainly focused on the fatigue failure behavior of planar ribbon-shaped geometries, while anti-fatigue design strategies and predictive failure criteria addressing 3D ribbon-shaped mesostructures are still lacking.

Simultaneously Regulating Uniform Zn Flux and Electron Conduction by MOF/rGO Interlayers for High-Performance Zn Anodes.

Nanomicro Lett 2021 Feb 15;13(1):73. Epub 2021 Feb 15.

School of Advanced Materials, Peking University Shenzhen Graduate School, Shenzhen, 518055, People's Republic of China.

Owing to the merits of low cost, high safety and environmental benignity, rechargeable aqueous Zn-based batteries (ZBs) have gained tremendous attention in recent years. Nevertheless, the poor reversibility of Zn anodes that originates from dendrite growth, surface passivation and corrosion, severely hinders the further development of ZBs. To tackle these issues, here we report a Janus separator based on a Zn-ion conductive metal-organic framework (MOF) and reduced graphene oxide (rGO), which is able to regulate uniform Zn flux and electron conduction simultaneously during battery operation.

School of Mechanical and Materials Engineering, Washington State University, Pullman, WA, 99164, USA.

Lithium-sulfur (Li-S) batteries are a promising candidate for the next-generation energy storage system, yet their commercialization is primarily hindered by polysulfide shuttling and uncontrollable Li dendrite growth. Here, a protein-based Janus separator was designed and fabricated for suppressing both the shuttle effect and dendrite growth, while facilitating the Li transport. The Li metal-protecting layer was a protein/MoS nanofabric with high ionic conductivity and good Li affinity, thus capable of homogenizing the Li flux and facilitating the Li transport. Read More

Inorganic-Organic Hybrid Janus Fillers for Improving the Thermal Conductivity of Polymer Composites.

ACS Appl Mater Interfaces 2019 Apr 22;11(13):12190-12194. Epub 2019 Mar 22.

Shandong Provincial Key Laboratory of Olefin Catalysis and Polymerization, Key Laboratory of Rubber-Plastics (Ministry of Education), School of Polymer Science and Engineering , Qingdao University of Science and Technology , Qingdao , Shandong 266042 , China.

Janus fillers represent a combination of inorganic thermally conductive silver nanoparticles and organic polystyrene brushes on one entity but different sides. They are of practical importance for polymer composites with high thermal conductivity because of the improved dispersion and reduced interfacial heat resistance. Moreover, benefiting from the sheetlike structure and single-side deposition of inorganic particles, Janus fillers tend to align such that the heat pathway is constructed in the composite films, when fabricated by layer-by-layer doctor blading.

Evolution of Self-Organized Microcapsules with Variable Conductivities from Self-Assembled Nanoparticles at Interfaces.

ACS Nano 2019 Mar 13;13(3):3483-3491. Epub 2019 Mar 13.

Institute of Chemistry and Biotechnology , Zurich University of Applied Sciences , Einsiedlerstrasse 31 , 8820 Waedenswil , Switzerland.

Self-organization dramatically affects the surface properties of materials on a macroscopic scale, such as wettability and adhesion. Fundamentally, it is equally interesting when self-organization at the nanoscale affects the bulk properties and thus provides a means to engineer the optoelectronic properties of the materials on larger scales. In this work, we report the evolution of conductive self-organized polymer microcapsules from a monomer emulsion droplet stabilized by a monolayer of conductive Janus nanoparticles (JNPs) via a mechanism resembling morphogenesis.

Liaoning Key Laboratory for Green Synthesis and Preparative Chemistry of Advanced Materials, College of Chemistry , Liaoning University , Shenyang 110036 , China.

Ultrathin two-dimensional NiS/Ni(OH) nanosheets (NiS/Ni(OH) NSs) were successfully filled within the hollow interiors of ammonium polyacrylate-functionalized polypyrrole nanotubes (NHPA/PPyNTs) by a simple solvothermal method. This kind of novel hierarchical nanostructures with typical structural features of a nanoconfined system, denoted by NiS/Ni(OH)/NHPA/PPyNTs, were prepared by two main sections: polyacrylic acid (PAA) was first polymerized on PPyNTs containing vinyl groups, and the obtained PAA/PPyNTs exhibited a typical Janus structure, whose external surface was covered with carboxyl groups and the internal surface was still covered with PPy chains; second, Ni ions as a precursor were facilely combined with -NH- segments in PPy chains by the coordination interaction under the solvothermal environment; therefore, NiS/Ni(OH) NSs (<1 nm) were well distributed on the internal surface of NHPA/PPyNTs by the in situ growth. Because of the synergistic effects of ionizable NHPA, PPy with good conductivity, NiS and Ni(OH) with electrocatalytical activity, as well as the nanoconfinement effect, the obtained NiS/Ni(OH)@NHPA/PPyNTs exhibited excellent electrocatalytic performance for detecting glucose.

Enhanced Multiple Exciton Generation in PbS|CdS Janus-like Heterostructured Nanocrystals.

ACS Nano 2018 Oct 21;12(10):10084-10094. Epub 2018 Sep 21.

Chemistry & Nanoscience Center , National Renewable Energy Laboratory , Golden , Colorado 80401 , United States.

Generating multiple excitons by a single high-energy photon is a promising third-generation solar energy conversion strategy. We demonstrate that multiple exciton generation (MEG) in PbS|CdS Janus-like heteronanostructures is enhanced over that of single-component and core/shell nanocrystal architectures, with an onset close to two times the PbS band gap. We attribute the enhanced MEG to the asymmetric nature of the heteronanostructure that results in an increase in the effective Coulomb interaction that drives MEG and a reduction of the competing hot exciton cooling rate.

Unconventional Janus Properties of Enokitake-like Gold Nanowire Films.

ACS Nano 2018 Aug 26;12(8):8717-8722. Epub 2018 Jul 26.

Department of Chemical Engineering , Monash University , Clayton , Victoria 3800 , Australia.

We report on unconventional Janus material properties of vertically aligned gold nanowire films that conduct electricity and interact with light and water in drastically different ways on its two opposing sides. These Janus-like properties originate from enokitake-like nanowire structures, causing the nanoparticle side ("head") to behave like bulk gold, yet the opposing nanowire side ("tail") behaves as discontinuous nanophases. Due to this Janus film structure, its head side is hydrophilic but its tail side is hydrophobic; its head side reflects light like bulk gold, yet its tail side is a broadband superabsorber; its tail side is less conductive but with tunable resistance.

Beijing National Laboratory for Condensed Matter Physics, Institute of Physics , Chinese Academy of Sciences , Beijing 100190 , China.

Electrolyte is the key to constructing the ionic transport paths and O gas diffusion routes in the cathode as well as maintaining the electrode interfacial stability in view of the complex chemistry of Li-O batteries. A novel poly(vinyl formal) (PVFM)-based Janus membrane, which is prepared via coating multiwalled carbon nanotubes (MWCNTs) on the porous side of the cross-linked PVFM membrane, has been proposed herein to achieve membrane-supporting gel polymer electrolyte (GPE) for Li-O batteries. Within Li-O batteries, the dense side of PVFM-based Janus membrane demonstrates a good compatibility with lithium metal anode, while the other side with MWCNTs coating reserves much more solvent on the surface, assisting the cathode to form enlarged electrolyte-wetted interface.
