Grafting Nanolayers of Ni and Co Catalysts Around the Edges of Hierarchical Zeolite 13X by Leveraging the Crystal's Defects for CO2 Methanation

Carbon Energy, Volume 8, Issue 6, June 2026.
The deactivation of nickel‐based catalysts at high temperatures poses a significant challenge in CO2 methanation processes. To address this, a strong metal–support interaction between nickel and the support was engineered by exploiting the crystal defects present in hierarchical porous zeolite 13X.

A FAST search for radio pulsations during the dormant state of the accreting millisecond pulsars IGR J00291+5934 and MAXI J1957+032

Astronomy & Astrophysics
Accreting millisecond pulsars (AMSPs) and transitional millisecond pulsars (tMSPs) are neutron star low-mass X-ray binaries that can evolve into recycled radio millisecond pulsars.

Proteomic and Super‐Resolution Analyses of Murine Brown Adipocyte‐Derived Extracellular Vesicles

Journal of Extracellular Biology, Volume 5, Issue 5, May 2026.
Graphical Abstract ABSTRACT Thermogenic brown adipocytes (BAs) are not only an energy sink but also regulate systemic metabolic health through secreted factors and extracellular vesicles (EVs). Here, we investigate the baseline profiles BA‐EVs and how cold‐induced thermogenesis alters the proteome of BA‐EVs.

The Emission Geometry of Pulsars with Interpulses

The Astrophysical Journal
We present polarization profiles of 23 pulsars exhibiting interpulse (IP) emissions using the Five-hundred-meter Aperture Spherical Radio Telescope. By applying the rotating vector model (RVM), we measured the inclination and impact angles for 16 pulsars,

Etude multilongueur d'onde des pulsars milliseconde [PDF]

, 2011
Les pulsars milliseconde (MSPs) sont des étoiles à neutrons caractérisées par une période de rotation de l'ordre de la milliseconde. Ils sont très probablement accélérés (recyclés) dans des systèmes binaires par transfert de moment cinétique lors d'une ...

A Perspective of Multi‐Reflecting TOF MS

Mass Spectrometry Reviews, Volume 45, Issue 3, Page 476-506, May/June 2026.
ABSTRACT Time‐of‐flight mass spectrometry (TOF MS) excels in rapid and high‐sensitivity analysis, making it a cornerstone of analytical chemistry. But as sample complexity explodes in omics studies, so does the need for higher resolving power to ensure accurate results.

The AO327 Drift Survey Catalog and Data Release of Pulsar Detections

The Astrophysical Journal Supplement Series
The AO327 drift survey for radio pulsars and transients used the Arecibo telescope from 2010 until its collapse in 2020. AO327 collected ∼3100 hr of data at 327 MHz with a time resolution of 82 μ s and a frequency resolution of 24 kHz.

Multi‐Tissue Omics Analysis Uncovers Translational Regulation Underlying Complex Traits in Pigs

Advanced Science, Volume 13, Issue 20, 9 April 2026.
Integrated multi‐omics across pig breeds and tissues reveals key principles of post‐transcriptional translational regulation and their contribution to trait formation. A gene network framework integrating transcriptomic and translatomic data is developed and applied to elucidate the genetic basis of meat production, offering new insights into mammalian

Nature of Ultralong Period Radio Transients: Could They Be Strange Dwarf Pulsars?

The Astrophysical Journal
Ultralong period radio transients (ULPTs), with periods of thousands of seconds, challenge conventional pulsar models. We propose that these isolated sources are strange dwarf (SD) pulsars—compact objects with a strange quark matter core surrounded by a ...

A study of radio continuum emission of the Milky Way Galaxy [PDF]

, 1996
The synchrotron emissivity distribution of the Milky Way Galaxy has been modelled from the 408 MHz allsky survey of Haslam et al.(1982) after separation of its thermal component with the help of IRAS 60 micron emission(Broadbent et al 1989).
