Masses, luminosities and dynamics of galactic molecular clouds [PDF]

open access: yes
Star formation in galaxies takes place in molecular clouds and the Milky Way is the only galaxy in which it is possible to resolve and study the physical properties and star formation activity of individual clouds. The masses, luminosities, dynamics, and

Two-Fluid MHD Simulations of Converging HI Flows in the Interstellar Medium. I: Methodology and Basic Results

open access: yes, 2008
We develop an unconditionally stable numerical method for solving the coupling between two fluids (frictional forces/heatings, ionization, and recombination), and investigate the dynamical condensation process of thermally unstable gas that is provided ...

Computational Simulations of Metal–Organic Frameworks to Enhance Adsorption Applications

open access: yesAdvanced Materials, EarlyView.
This review highlights the significance of molecular simulations in expanding the understanding of metal–organic frameworks (MOFs) and improving their gas adsorption applications. The historical development and implementation of molecular simulations in the MOF field are given, high‐throughput computational screening studies used to unlock the ...

Velocity Structure and Molecular Formation in the Polaris Molecular Cloud

open access: yesThe Astrophysical Journal
We present a wide-field $(60^{\prime} \times 30^{\prime} )$ study of a dense region within the Polaris Flare using ^12 CO, ^13 CO, and C ^18 O ( J  = 1–0) observations at 15″ resolution, obtained with the Nobeyama 45 m Radio Telescope.

Larson's third law and the universality of molecular cloud structure

open access: yes, 2010
Larson (1981) first noted a scaling relation between masses and sizes in molecular clouds that implies that these objects have approximately constant column densities.

Machine‐Learning‐Aided Advanced Electrochemical Biosensors

open access: yesAdvanced Materials, EarlyView.
Electrochemical biosensors are highly sensitive, portable, and versatile. Advanced nanomaterials enhance their performance, while machine learning (ML) improves data analysis, minimizes interference, and optimizes sensor design. Despite progress in both fields, their combined potential in diagnostics remains underexplored.

From the warm magnetized atomic medium to molecular clouds

open access: yes, 2008
{It has recently been proposed that giant molecular complexes form at the sites where streams of diffuse warm atomic gas collide at transonic velocities.} {We study the global statistics of molecular clouds formed by large scale colliding flows of warm ...

Robust Full‐Surface Bonding of Substrate and Electrode for Ultra‐Flexible Sensor Integration

open access: yesAdvanced Materials, EarlyView.
A direct hybrid bonding method that enables both gold and parylene bonding without adhesives is developed. This technique achieves full‐surface direct bonding of electrodes and substrates in flexible electronic connections. The method offers high flexibility, stable mechanical durability, and high‐resolution interconnections, accommodating varying ...
