From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

On the Destruction and Humanitarianisation of the Health System in Gaza and the Need for a Biopolitical Bioethics

open access: yesBioethics, Volume 40, Issue 8, Page 793-807, October 2026.
ABSTRACT This paper examines Israel's destruction and ‘humanitarianisation’ of Palestinian health systems, arguing that this should be understood as an instance of ‘necropolitics,’ as conceived by Achille Mbembe. We review the extensive, long‐term destruction of health systems in Palestine before 7 October 2023 and the catastrophic acceleration of that

The impact of the ambient gas density on the evolution of supernova remnants [PDF]

open access: yes, 2018
This thesis presents a theoretical discussion of the full evolution of Supernova Remnants (SNRs), that includes the thermalization of the SN ejecta, the Sedov-Taylor and Snowplough stages of the SNR evolution.

Host‐Associated Differentiation in a Parasitoid Wasp Connected to Venom‐Related but Not Chemosensory Genes

open access: yesMolecular Ecology, Volume 35, Issue 19, October 2026.
ABSTRACT The mechanisms driving the megadiversity of parasitic wasps remain a central question in evolutionary ecology. To investigate the genomic architecture underlying host‐associated differentiation in parasitic wasps, we generated a de novo genome assembly and performed whole‐genome re‐sequencing of 17 populations of the parasitoid wasp Asecodes ...

Modeling supernova remnants: effects of diffusive cosmic-ray acceleration on the evolution and application to observations [PDF]

open access: yes, 2011
We present numerical models for supernova remnant evolution, using a new version of the hydrodynamical code SUPREMNA. We added a cosmic-ray diffusion equation to the code scheme, employing a two-fluid approximation.

Azidophosphonamido Rhodium(I) and Iridium(I) Complexes: Synthesis, Properties, and Linkage Isomerism

open access: yesChemistry – A European Journal, Volume 32, Issue 36, 24 September 2026.
A family of azidophosphonamido ligands and their corresponding rhodium(I) and iridium(I) complexes were synthesized. The rich reaction chemistry of these species revealed unusual linkage isomerization processes and bonding motifs. M = Rh, Ir; Mes = 2,4,6‐Me3C6H2. ABSTRACT A series of azidophosphonamido rhodium(I) and iridium(I) complexes ([iPr2P(N3R)NR]

The origin of cosmic rays and TeV gamma-ray astronomy

open access: yesEPJ Web of Conferences, 2013
Cosmic rays are accelerated to high energies in Galactic and extragalactic objects like Supernova remnants (SNR) and active galactic nuclei (AGN). How these accelerators work and how efficient they accelerate different types of particles to energies of ...

One‐Dimensional Materials Supported in Two‐Dimensional Van der Waals Metal–Organic Frameworks with Optical Anisotropy Switching via Twist‐Engineering

open access: yesAdvanced Materials, Volume 38, Issue 51, 11 September 2026.
We introduce a molecular strategy to assemble one‐dimensional (1D) materials into two‐dimensional (2D) van der Waals metal–organic frameworks (MOFs). Crystals of [FeX(pzX)(bpy)] (X = Cl, F) form anisotropic 2D layers that can be mechanically exfoliated into thin sheets.

Mixing of materials in magnetized core-collapse supernova remnants

open access: yes, 2023
Core-collapse supernova remnants are structures of the interstellar medium (ISM) left behind the explosive death of most massive stars ( ?40 M-?). Since they result in the expansion of the supernova shock wave into the gaseous environment shaped by the
