Fabrication of Nanoscale Circuits on Inkjet-Printing Patterned Substrates.

Nanoscale circuits are fabricated by assembling different conducting materials (e.g., metal nanoparticles, metal nano-wires, graphene, carbon nanotubes, and conducting polymers) on inkjet-printing patterned substrates. This nonlitho-graphy strategy opens a new avenue for integrating conducting building blocks into nanoscale devices in a cost-efficient manner.

From Soft Self-Healing Gels to Stiff Films in Suckerin-Based Materials Through Modulation of Crosslink Density and β-Sheet Content.

Suckerins are block copolymer-like structural proteins constituting the building blocks of the strong squid sucker-ring teeth. Here, recombinant suckerin-19 is processed into biomaterials spanning a wide range of elasticity, from very soft hydrogels to stiff films with elastic modulus in the gigapascal range. The elasticity is controlled by the interplay between β-sheet content and induced di-tyrosine crosslinking.

Rotation-Misfit-Free Heteroepitaxial Stacking and Stitching Growth of Hexagonal Transition-Metal Dichalcogenide Monolayers by Nucleation Kinetics Controls.

2D vertical stacking and lateral stitching growth of monolayer (ML) hexagonal transition-metal dichalcogenides are reported. The 2D heteroepitaxial manipulation of MoS2 and WS2 MLs is achieved by control of the 2D nucleation kinetics during the sequential vapor-phase growth. It enables to create the hexagon-on-hexagon unit cell stacking and the hexagon-by-hexagon stitching without interlayer rotation misfits.

Adaptable Hydrogel Networks with Reversible Linkages for Tissue Engineering.

Adaptable hydrogels have recently emerged as a promising platform for three-dimensional (3D) cell encapsulation and culture. In conventional, covalently crosslinked hydrogels, degradation is typically required to allow complex cellular functions to occur, leading to bulk material degradation. In contrast, adaptable hydrogels are formed by reversible crosslinks. Through breaking and re-formation of the reversible linkages, adaptable hydrogels can be locally modified to permit complex cellular functions while...

Simultaneous Enhancement of Electrical Conductivity and Thermopower of Bi2 Te3 by Multifunctionality of Native Defects.

Simultaneous increases in electrical conductivity (up to 200%) and thermopower (up to 70%) are demonstrated by introducing native defects in Bi2 Te3 films, leading to a high power factor of 3.4 × 10(-3) W m(-1) K(-2) . The maximum enhancement of the power factor occurs when the native defects act beneficially as electron donors as well as energy filters to mobile electrons. They also act as effective phonon scatterers.

Direct Pen Writing of High-Tc , Flexible Magnesium Diboride Superconducting Arrays.

High-Tc , flexible MgB2 -nanowire-based superconducting arrays are fabricated via a direct pen writing method on both copper foils and poly(dimethylsiloxane) (PDMS) substrates. Such superconducting arrays constitute a new approach for fabricating superconducting devices. The realization of a PDMS-based device demonstrates the potential for expanding this material into other high-Tc superconductor systems, which may lead to novel ways of driving the development of "real-life" applications.

A millimeter thin rubber-like solid-state lighting module is reported. The fabrication of the lighting module incorporates assembly and electrical connection of light-emitting diodes (LEDs). The assembly is achieved using a roll-to-roll fluidic self-assembly. The LEDs are sandwiched in-between a stretchable top and bottom electrode to relieve the mechanical stress. The top contact is realized using a lamination technique that eliminates wire-bonding.

Lithium-Sulfur Batteries: A Lightweight TiO2 /Graphene Interlayer, Applied as a Highly Effective Polysulfide Absorbent for Fast, Long-Life Lithium-Sulfur Batteries (Adv. Mater. 18/2015).

An integrated, selective graphene/TiO2 interlayer structure is developed by Z. Yang, S. Huang, and co-workers on page 2891 to further mitigate polysulfide (PS) diffusion. In this rational design, the porous graphene affords an additional electrically conductive network and physically traps PS; as an added bonus, the TiO2 in the graphene/TiO2 barrier film further chemically suppresses the dissolution of PS, and alleviates the undesirable shuttle effect.
