Tunable Thermoshrinkable Hydrogels for 4D Fabrication of Cell‐Seeded Channels

open access: yesAdvanced Functional Materials, EarlyView.
A thermoresponsive polymer with methacrylate groups for photo‐cross‐linking, based on polyethylene glycol, N‐isopropylacrylamide, and 2‐hydroxyethyl acrylate is synthetized to yield hydrogels that shrink upon temperature increase. The new polymer enables the fabrication of cell‐laden perfusable channels with diameters below 200 µm by combining ...

A CO Line and Infrared Continuum Study of the Active Star-Forming Complex W51

open access: yes, 2010
We present the results of an extensive observational study of the active star-forming complex W51 that was observed in the J=2-1 transition of the 12CO and 13CO molecules over a 1.25 deg x 1.00 deg region with the University of Arizona Heinrich Hertz ...

SUPERNOVA-ENHANCED COSMIC-RAY IONIZATION AND INDUCED CHEMISTRY IN A MOLECULAR CLOUD OF W51C [PDF]

open access: yes, 2011
Cosmic rays (CRs) pervade the Galaxy and are thought to be accelerated in supernova shocks. The interaction of CRs with dense interstellar matter has two important effects: (1) high-energy (≳1 GeV) protons produce γ-rays by π0-meson decay and (2) low ...

Atomic Size Misfit for Electrocatalytic Small Molecule Activation

open access: yesAdvanced Functional Materials, EarlyView.
This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

Regulating the Interphase Strain in High‐Entropy Oxide Thin Films – An Approach to Attaining Giant Energy Storage Capability under Moderate Electric Fields

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates an interphase strain engineering strategy to regulate capacitive energy storage performance in high‐entropy oxide thin films. Through introducing pyrochlore nanocolumns, the polarization response of perovskite unit cells is strengthened, yielding recoverable energy densities up to 93 J cm−3 with an efficiency of 83% under ...

Formation of Turbulent and Magnetized Molecular Clouds via Accretion Flows of HI Clouds

open access: yes, 2012
Using 3D MHD simulation with the effects of radiative cooling/heating, chemical reactions, and thermal conduction, we investigate the formation of molecular cloud in the ISM.

GROMACS 4.5: a high-throughput and highly parallel open source molecular simulation toolkit

open access: yesBioinform., 2013
MOTIVATION Molecular simulation has historically been a low-throughput technique, but faster computers and increasing amounts of genomic and structural data are changing this by enabling large-scale automated simulation of, for instance, many conformers ...

Probing the evolution of molecular cloud structure II. From chaos to confinement [PDF]

open access: yes, 2011
We present an analysis of the large-scale molecular cloud structure and of the stability of clumpy structures in nearby molecular clouds. In our recent work, we identified a structural transition in molecular clouds by studying the probability ...

High altitude molecular clouds [PDF]

open access: yesThe Astrophysical Journal, 1994
A population of molecular clouds with a significantly greater scale height than that of Giant Molecular Clouds has been identified by examining maps of the latitude distribution of the $^{12}CO(1-0)$ emission in the first quadrant of the Galaxy. These clouds are found by identifying emission more than 2.6 times the scale-height away from the galactic ...

Enhancing CoFe Catalysts with V2CTX MXene‐Derived Materials for Anion Exchange Membrane Electrolyzers

open access: yesAdvanced Functional Materials, EarlyView.
MXene dervied CoFe composites show increased initial Oxygen Evolution Reaction (OER) activity compared to the pure CoFe and MXene in an Anion Exchange Membrane device. Vanadium vacancies in the MXene plays a role in increased OER activity and hinders Fe leaching in the AEM device over using the pure V2C MXene as a support material for the CoFe ...
