Zinc Oxide and Graphitic Carbon Nitride/ZnO Nanocomposites in Food Safety and Preservation: Synthesis, Antimicrobial Mechanisms, and Application Prospects

open access: yesFood Science &Nutrition, Volume 14, Issue 11, November 2026.
ZnO and g‐C3N4/ZnO S‐scheme heterojunctions are synthesized via conventional, green, and biogenic routes. They combat foodborne pathogens and degrade mycotoxins through ROS generation, Zn2+ release, and membrane disruption, enabling antimicrobial packaging, photocatalytic decontamination, and nanobiosensing. However, migration, toxicity, and regulatory

NinjaSat: Astronomical X-ray CubeSat observatory

open access: yesPublications of the Astronomical Society of Japan
Abstract NinjaSat is an X-ray CubeSat designed for agile, long-term continuous observations of bright X-ray sources, with the size of 6U ($112.7\times 237.1\times 340.5$ mm3) and a mass of 8 kg. NinjaSat is capable of pointing at X-ray sources with an accuracy of less than $0.^{\!\!\!\circ }1$ ($2\sigma$ confidence level) with three-axis

Results of X-ray and optical monitoring of SCO X-1 [PDF]

open access: yes, 1974
Sco X-1 was monitored at optical and X-ray wavelengths from 1970 April 26 to 1970 May 21. The optical observations were made at six observatories around the world and the X-ray observations were made by the Vela satellites.

Impact of Solar Radiation Pressure, Coriolis Force, and Exobase Conditions on Terrestrial Exospheric Density: MATE Simulation Results

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract We improved the Model for Analyzing the Terrestrial Exosphere (MATE), a kinetic exosphere model, by incorporating solar radiation pressure and Coriolis force arising from the Earth's revolution around the Sun, in addition to Earth's gravity, to investigate their impacts on the terrestrial exospheric hydrogen density. Under constant and uniform

Co‐Located P and S‐Wave Teleseismic Velocity Tomography of the Alaskan Upper Mantle

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Seismic velocity (V) $(V)$ provides key insights into the structure and thermodynamic state of the Earth's mantle. Leveraging the dense broadband coverage of the Transportable Array (TA) in Alaska, we compiled a data set of 67,671 P $P$‐wave differential travel times and 114,205 multi‐frequency differential travel‐time measurements for S $S ...

Bayesian Inference of fine-features of dense matter EOS from future high-precision data of neutron star radii [PDF]

open access: yesEPJ Web of Conferences
Future high-precision X-ray and gravitational wave observatories are expected to measure the radii of neutron stars (NSs) with an accuracy better than about 0.1 km. However, it remains unclear what particular aspects of the Equation of State (EOS) and to

Active Neutron Spectroscopy to Determine the Hydration of Low‐Mass, Sealed Mars Samples

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract Mars samples returned to Earth as part of the NASA Mars Sample Return program (MSR) will be subject to a wide range of scientific analyses, many of which will have important implications for the search for life/habitability and planetary evolution. Critical to both of these is the hydration state of the samples. But to ensure the most accurate

Sulfidation Reaction Mechanisms of Olivine and Diopside at Mercury's Reducing Conditions

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract The surface of Mercury contains elevated amounts of sulfur of up to 4 wt.%. Volcanic degassing of S from the interior of the planet could have initiated sulfidation reactions between the degassed S and surface materials in the planet's past, leading to the observed surface S enrichment.
