Advanced Functional Materials, EarlyView.In this study, the interplay of dipolar dynamics and ionic charge transport in MOF compounds is investigated. Synthesizing the novel structure CFA‐25 with integrated freely rotating dipolar groups, local and macroscopic effects, including interactions with Cs cations are explored.

Advanced Functional Materials, EarlyView.The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Multiwavelength Variability Analysis of 3C 279
Frontiers in Astronomy and Space Sciences, 2017 We present a multifrequency analysis of the variability in the flat-spectrum radio quasar 3C 279 from 2008 to 2014. Our multiwavelength datasets range from 1 mm to gamma-rays, with additional optical polarimetry.

20cm VLA radio-continuum study of M31: Images and point source catalogues [PDF]
Serbian Astronomical Journal, 2012 We present a series of new high-sensitivity and high-resolution radio-continuum images of M31 at λ=20 cm (ν=1.4 GHz). These new images were produced by merging archived 20 cm radio-continuum observations from the Very Large Array (VLA) telescope.

Upper Limits to the Proper Motions of JuMBO 24, a Jupiter-mass Binary Object Candidate in Orion
The Astrophysical JournalUsing JWST near-infrared data of the inner Orion Nebula, S. G. Pearson & M. J. McCaughrean detected 40 binary systems they proposed to be Jupiter-mass binary objects (JuMBOs)—although their actual nature is still in debate. Only one of the objects, JuMBO

Estimation of the Flux at 1450 MHz of OB Stars for FAST and SKA
The Astronomical Journal, 2023 Radio observation is crucial to understanding the wind mechanism of OB stars but very scarce. This work estimates the flux at 1450 MHz ( S _1.4GHz ) of about 5000 OB stars identified by the LAMOST spectroscopic survey and confirmed by the Gaia ...
