30 inch Roll-Based Production of High-Quality Graphene Films for Flexible Transparent Electrodes [PDF]
Nature Nanotechnology, 2010 We report that 30-inch scale multiple roll-to-roll transfer and wet chemical doping considerably enhance the electrical properties of the graphene films grown on roll-type Cu substrates by chemical vapor deposition.

Squeezed bispectrum and one-loop corrections in transient constant-roll inflation [PDF]
Journal of Cosmology and Astroparticle Physics, 2023 In canonical single-field inflation, the production of primordial black holes (PBH) requires a transient violation of the slow-roll condition. The transient ultra slow-roll inflation is an example of such scenarios, and more generally, one can consider ...

Ultra-slow-roll inflation with quantum diffusion [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 We consider the effect of quantum diffusion on the dynamics of the inflaton during a period of ultra-slow-roll inflation. We extend the stochastic-δ𝒩 formalism to the ultra-slow-roll regime and show how this system can be solved analytically in both the ...

Efficient selenium-integrated TADF OLEDs with reduced roll-off
Nature Photonics, 2022 Organic light emitters based on multiresonance-induced thermally activated delayed fluorescent materials have great potential for realizing efficient, narrowband organic light-emitting diodes (OLEDs).

Roll, Roll, Roll your Root [PDF]
Proceedings of the Internet Measurement Conference, 2019 The DNS Security Extensions (DNSSEC) add authenticity and integrity to the naming system of the Internet. Resolvers that validate information in the DNS need to know the cryptographic public key used to sign the root zone of the DNS. Eight years after its introduction and one year after the originally scheduled date, this key was replaced by ICANN for ...

Bounds on slow roll and the de Sitter Swampland [PDF]
Journal of High Energy Physics, 2018 The recently introduced swampland criterion for de Sitter [17] can be viewed as a (hierarchically large) bound on the smallness of the slow roll parameter 𝜖V.

Physical Review Letters, 2010 We present the results of a combined experimental and theoretical investigation of rolling elastic ribbons. Particular attention is given to characterizing the steady shapes that arise in static and dynamic rolling configurations. In both cases, above a critical value of the forcing (either gravitational or centrifugal), the ribbon assumes a two-lobed,

Effects of Sway and Roll Excitations on Sloshing Loads in a KC-1 Membrane LNG Tank
Polish Maritime Research, 2023 This study investigates the effects of sway and roll excitations on sloshing liquid loads in a tank, using Ansys Fluent software. The model considered in the study is a 1:50 scaled membrane-type tank, based on a KC-1 membrane LNG tank designed by Korea ...

A High Compressibility Pressure—Sensitive Structure Based on CB@PU Yarn Network
Sensors, 2018 In this work, a piezoresistive sensor structure based on carbon black (CB)@polyurethane (PU) yarn material was developed. Specifically, CB@PU yarn was constructed by the polymer-mediated water-based electrostatic deposition method.
