Direct Ink Writing of Conductive Hydrogels

open access: yesAdvanced Functional Materials, EarlyView.
This review examines the use of direct ink writing (DIW) for fabricating conductive hydrogels with customizable 3D structures. It outlines the rheological requirements for successful DIW, followed by an exploration of the materials and ink formulations used to impart electronic and/or ionic conductivity to hydrogels while maintaining printability ...

The transformation and quenching of simulated gas-rich dwarf satellites within a group environment [PDF]

open access: yes, 2015
The underlying mechanisms driving the quenching of dwarf-mass satellite galaxies remain poorly constrained, but recent studies suggest they are particularly inefficient for those satellites with stellar mass 10$^{\rm 9}$ M$_{\odot}$. We investigate the characteristic evolution of these systems with chemodynamical simulations and idealised models of ...

Hinode Calibration for Precise Image Co-alignment between SOT and XRT (November 2006 -- April 2007)

open access: yes, 2007
To understand the physical mechanisms for activity and heating in the solar atmosphere, the magnetic coupling from the photosphere to the corona is an important piece of information from the Hinode observations, and therefore precise positional alignment

Transit, the Navy Navigation Satellite System

open access: yesNavigation, 1971
So much has happened in this world since October 4, 1957, it is difficult to realize that fewer than 14 years have passed since the launch of Sputnik I, the first artificial earth satellite. Technology has leapt forward from those first "beeps" in space to produce worldwide communication and weather monitoring systems, spies-in-the sky, astronomical ...

Universal Superconductivity in FeTe and All‐Iron‐Based Ferromagnetic Superconductor Heterostructures

open access: yesAdvanced Functional Materials, EarlyView.
The first all‐iron‐based ferromagnetic superconductor heterostructures with high‐temperature superconductivity and strong ferromagnetism aredemonstrated. From this, it is discovered that FeTe becomes universallysuperconducting with a minute level of cationic impurities through doping ordiffusion from neighboring layers, suggesting its ground state can ...

Direct measurements of laser light aberration from the ARTEMIS geostationary satellite through thin clouds [PDF]

open access: yesarXiv, 2015
A precise ground based telescope system was developed for laser communication experiments with the geostationary satellite ARTEMIS of ESA. Precise tracking of the satellite was realized by using time resolved coordinates of the satellite. During the experiments, the time propagation of laser signal from the satellite and the point-ahead angle for the ...

Characterizing dw1335-29, a recently discovered dwarf satellite of M83 [PDF]

open access: yes, 2016
The number, distribution, and properties of dwarf satellites are crucial probes of the physics of galaxy formation at low masses and the response of satellite galaxies to the tidal and gas dynamical effects of their more massive parent.To make progress, it is necessary to augment and solidify the census of dwarf satellites of galaxies outside the Local

Modeling the Orbital Sampling Effect of Extrasolar Moons

open access: yes, 2016
The orbital sampling effect (OSE) appears in phase-folded transit light curves of extrasolar planets with moons. Analytical OSE models have hitherto neglected stellar limb darkening and non-zero transit impact parameters and assumed that the moon is on a

Mediation of Oxidation and Spin States of Fe/P‐CoO2 Core–Shell Structures Catalysts for Oxygen Evolution Reaction

open access: yesAdvanced Functional Materials, EarlyView.
Fe‐cationic and P‐anionic coordination, as fabricated in Co0.75Fe0.25P/MWCNTs, effectively optimizes the adsorption of OER intermediates (OH*, O*), promoting direct O*─O* coupling and avoiding the formation of unstable OOH* intermediate. This process is accompanied by an asynchronous transfer of electrons and protons, resulting in the formation of a ...
