Collisional Buildup of Molecular Clouds: Mass and Velocity Spectra [PDF]
, 1996 We have studied the evolution of a local region of molecular clouds, moving in the mean gravitational potential of the Galactic disk. The clouds interact gravitationally with one another and undergo inelastic collisions.

Turbulent driving scales in molecular clouds
, 2009 Context. Supersonic turbulence in molecular clouds is a dominant agent that strongly affects the clouds' evolution and star formation activity. Turbulence may be initiated and maintained by a number of processes, acting at a wide range of physical ...

Advanced Materials, EarlyView.Flexible neutral Zn‐air batteries achieving a remarkable 3000‐cycle lifespan and withstanding 1000 bending cycles are reported. This performance is realized by employing a 3D physically cross‐linked neutral hydrogel electrolyte that integrates high adhesion, self‐healing, O2 permeability, and CO2 tolerance to resolve critical stability challenges ...

Cloud-to-cloud Velocity Dispersions Across a Local Arm Segment
The Astrophysical JournalUsing a large sample of 9617 molecular clouds (MCs) from the Milky Way Imaging Scroll Painting survey, we mainly measure one-dimensional cloud-to-cloud velocity dispersions across a 450 deg ^2 segment of the Local Arm in the Galactic second quadrant.

Advanced Materials, EarlyView.A dual‐additive electrolyte strategy is developed to address the hydrolysis of I+ in the aqueous electrolytes. The steric‐hindrance effect of TES− effectively shields I+ from nucleophilic attacks by hydroxyl groups, facilitating the reversible I−/I0/I+ conversion with four‐electron transfer.

Molecular Clouds at High Z [PDF]
Symposium - International Astronomical Union, 1991 The evidence for the existence of molecular clouds at large distances from the Galactic plane is reviewed. The molecular clouds at high Galactic latitudes are shown to be largely confined to the Galactic plane. There is evidence for one giant molecular cloud as much as four scale heights from the Galactic plane, but given the sample size from which the

The Astronomical JournalTo reveal the origin of the mini-starbursts in the Milky Way, we carried out large-scale CO observations toward the RCW 106 giant molecular cloud (GMC) complex using the NANTEN2 4 m radio telescope operated by Nagoya University.

UniverseIn the present work, we suggest a new approach for studying the equilibrium states of an hydrodynamic isothermal turbulent self-gravitating system as a statistical model for a molecular cloud. The main hypothesis is that the local turbulent motion of the

Fragmentation of magnetically-supported, weakly-ionized molecular clouds
, 2011 We follow the evolution and fragmentation of isolated, magnetically-supported, weakly- ionized, self-gravitating molecular clouds in three dimensions. Although the model clouds are supported by the magnetic field, high-density, magnetically-supercritical

E. coli Extracellular Matrix: A Tunable Composite With Hierarchical Structure
Advanced Materials, EarlyView.The complex composite‐like mechanical behavior of E. coli biofilm matrix is the result of a synergic contribution of the rigid curli and swelling pEtN‐cellulose, and emerges from specific ratio and assembly conditions. The interactions between the two fibers govern biofilm hydration and characteristic wrinkling patterns, providing crucial insights for ...
