Anisotropic charge trapping in phototransistors unlocks ultrasensitive polarimetry for bionic navigation

open access: yesNature Communications, 2022
The direct linear dichroism photodetection without external optics is crucial for applications. Here, Jie et al. exploit the anisotropic charge trapping in organic phototransistors to achieve the dichroic ratio of 104 and to demonstrate a polarizer-free ...

Thermal design and analysis of high power star sensors

open access: yesCase Studies in Thermal Engineering, 2015
The requirement for the temperature stability is very high in the star sensors as the high precision needs for the altitude information. Thermal design and analysis thus is important for the high power star sensors and their supporters.

The influence of initial orbital period on helium and carbon-oxygen core masses in massive case a binary systems with low accretion efficiency [PDF]

open access: yesSerbian Astronomical Journal, 2022
The evolutionary models of 33 massive Case A binary systems in mass range from 30M⊙ to 40M⊙ with initial orbital periods of 3, 4 and 5 days, accretion efficiency of 10% and at the solar metallicity are presented. The models are obtained with the

Gas phase Elemental abundances in Molecular cloudS (GEMS) [PDF]

open access: yesEPJ Web of Conferences, 2022
Gas phase Elemental abundances in Molecular CloudS (GEMS) is an IRAM 30m Large Program aimed at determining the elemental abundances of carbon (C), oxygen (O), nitrogen (N), and sulphur (S) in a selected set of prototypical star forming filaments ...

Observational evidence for composite grains in an AGB outflow. MgS in the extreme carbon star LL Pegasi [PDF]

open access: yes, 2012
The broad 30 μm feature in carbon stars is commonly attributed to MgS dust particles. However, reproducing the 30 μm feature with homogeneous MgS grains would require much more sulfur relative to the solar abundance.

SDSS J142625.71+575218.3: A Prototype for A New Class of Variable White Dwarf [PDF]

open access: yes, 2008
We present the results of a search for pulsations in six of the recently discovered carbon-atmosphere white dwarf ("hot DQ") stars. On the basis of our theoretical calculations, the star SDSS J142625.71 + 575218.3 is the only object expected to pulsate ...

Discovery of a hyperalkaline liquid condensed phase: significance toward applications in carbon dioxide sequestration

open access: yesFrontiers in Bioengineering and Biotechnology
Bicarbonate ion-containing solutions such as seawater, natural brines, bovine serum and other mineralizing fluids have been found to contain hyperalkaline droplets of a separate, liquid condensed phase (LCP), that have higher concentrations of ...
