Iron‐Substituted Zn‐Al LDH‐Derived Mixed Oxides: Tailoring Structure, Composition and Redox Properties for Efficient CO2‐to‐Olefins Conversion

ChemCatChem, Volume 18, Issue 15, 14 August 2026.
LDH‐derived Zn‐Fe‐Al mixed oxides exhibited 40% CO2 conversion and 10.6% yield of light olefins. The composition and the properties of the mixed oxides strongly influenced the selectivity of products, while ZnFe2O4 and iron carbide structure promoted the conversion and the selectivity of light olefins.

On the origins of part-time radio pulsars

, 2007
Growing evidence suggests that some radio pulsars only act sporadically. These 'part-time' pulsars include long-term nulls, quasi-periodic radio flares in PSR B1931+24, as well as the so-called Rotating Radio Transients (RRATs).

A 350 MHz Green Bank Telescope Survey of Unassociated Fermi LAT Sources: Discovery and Timing of 10 Millisecond Pulsars

The Astrophysical Journal
We have searched for radio pulsations toward 49 Fermi Large Area Telescope (LAT) 1FGL Catalog γ -ray sources using the Green Bank Telescope at 350 MHz. We detected 18 millisecond pulsars (MSPs) in blind searches of the data; 10 of these were discoveries ...

The first NenuFAR pulsar catalogue

Astronomy & Astrophysics
Context. The radio frequency range below 100 MHz has been unexplored until recently for extended pulsar population studies. We present the first low-frequency pulsar census of the northern sky with the NenuFAR radio telescope (10–85 MHz), performed ...

Investigations on the Role of Support and Synthesis Procedure for the Rux–Cuy/CNT‐Catalysed Hydrogenolysis of Glycerol to 1,2‐Propanediol

ChemistryOpen, Volume 15, Issue 7, July 2026.
Sophisticated carbon supports like single‐ and multiwall carbon nanotubes as well as Globugraphite were used for the synthesis of bimetallic Ru–Cu catalysts, which were tested in a multi batch reactor setup for the chemical hydrogenolysis of glycerol to 1,2‐propanediol (1,2‐PDO) at 220 °C under 30 bar of hydrogen pressure in aqueous solution. Tailoring

Discovery of two millisecond pulsars in Fermi sources with the Nancay Radio Telescope [PDF]

, 2011
We report the discovery of two millisecond pulsars in a search for radio pulsations at the positions of \emph{Fermi Large Area Telescope} sources with no previously known counterparts, using the Nançay radio telescope.

Activin Signaling Inhibitors in Pulmonary Hypertension: A State‐of‐the‐Art Review

Pulmonary Circulation, Volume 16, Issue 3, July 2026.
ABSTRACT Pulmonary arterial hypertension (PAH) is a disease of abnormal pulmonary vascular remodeling and vascular obliteration that results in right heart failure and death. PAH pathogenesis is strongly associated with mutations of the Transforming Growth Factor Beta (TGF‐β) superfamily signaling pathway, which has previously been challenging to ...

The statistics of radio pulsars: A spark model [PDF]

, 2001
We use Monte Carlo techniques to relate a theoretical pulsar emission model to the observed distributions of pulse period, magnetic field strength, distance, and luminosity of radio pulsars.
