Hierarchical structure of the interstellar molecular clouds and star formation

open access: yesOpen Astronomy, 2017
Properties of the hierarchical structures of interstellar molecular clouds are discussed. Particular attention is paid to the statistical correlations between velocity dispersion and size, and between the magnetic field strength and gas density.

Reviewing Molecular Clouds

open access: yes, 2017
The star formation process involves a wide range of spatial scales, densities and temperatures. Herschel observations of the cold and low density molecular gas extending tens of parsecs, that constitutes the bulk of the molecular clouds of the Milky Way, have shown a network of dense structures in the shape of filaments.

Dynamically Adaptive Wrinkle‐Structured Light‐Regulating Films for Energy‐Efficient Buildings

open access: yesAdvanced Functional Materials, EarlyView.
A scalable, moisture‐responsive cellulose nanofibril/polyvinyl alcohol (CNF/PVA)‐glycerol film with switchable wrinkled surfaces for dynamic light regulation is developed. Compared to glass, it achieves tunable light diffusion for daylight harvesting, thermal regulation, and privacy control.

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.

Stochastically Generated Digital Twins of 3D Solid‐State Electrolyte Architecture

open access: yesAdvanced Functional Materials, EarlyView.
Digital Twins of random porous tape‐cast solid‐state battery architectures across µm to mm feature sizes from FIB‐SEM to X‐Ray µCT, respectively. Abstract Solid‐state lithium batteries (SSBs) have the potential to overcome conventional Li‐ion batteries in performance and safety.
