Generation of Cosmic rays in Historical Supernova Remnants

EPJ Web of Conferences, 2013
We present the results of observations of two types of Galactic supernova remnants with the SHALON mirror Cherenkov telescope of Tien-Shan high-mountain Observatory: the shell-type supernova remnants Tycho, Cas A and IC 443; plerions Crab Nebula, 3c58 ...

Multi-Wavelength View of Supernova Remnants

Acta Polytechnica CTU Proceedings, 2014
This contribution gives a very short overview on the emission of supernova remnants and the processes that are responsible for both the thermal and non-thermal origins of the emission, typically observed in radio, X-rays, and up to gamma-rays. We discuss

Practical Aspects of X-ray Imaging Polarimetry of Supernova Remnants and Other Extended Sources

Galaxies, 2018
The new generation of X-ray polarisation detectors, the gas pixel detectors, which will be employed by the future space missions IXPE and eXTP, allows for spatially resolved X-ray polarisation studies.

Aluminum versus Gallium: Differences in Bis(bis(trimethylsilyl)methyl) Element Halides, Hydrides, and Oxygen‐Bridged E/P Frustrated Lewis Pairs

ChemistryEurope, EarlyView.
Reacting Bis2GaBr (Bis = CH(SiMe3)2) with Bis2AlH selectively yields Bis2GaH, a monomeric hydride in solution, characterized by diffusion ordered spectroscopy NMR, infrared spectroscopy and indirectly via hydrogallation. A one‐pot route enables frustrated Lewis pairs Bis2EOPtBu2 (E = Al, Ga), with the gallium analog splitting H2 and showing a dynamic ...

Establishing Indium in Frustrated Lewis Pair Chemistry: From Synthesis to Catalytic Applications

ChemistryEurope, EarlyView.
Not that hard: The effects of chemical hardness of the soft FLP tBu2InCH2PtBu2 and its pyridine‐adduct tBu2In(py)CH2PtBu2 were examined in adduct formation reactions toward H2, CO2, and CS2. The frustrated Lewis pair shows catalytic activity in the reduction of CO2 with pinacolborane.

Hubble Space Telescope Proper Motion Measurements of Supernova Remnant N132D: Center of Expansion and Age

The Astrophysical Journal, 2023
We present proper motion measurements of the oxygen-rich ejecta of the LMC supernova remnant N132D using two epochs of Hubble Space Telescope Advanced Camera for Surveys data spanning 16 years.

Engineering a Stable Solid–Electrolyte Interphase through a Novel Trifluoromethyl‐Free Lithium Salt for Lithium Metal Polymer Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The motivation behind the development of the new lithium salt LiDFFSI is to combine the advantages of both LiFSI and LiDFSI salts. LiDFFSI offers high ionic conductivity and enhanced compatibility with aluminum current collectors. Additionally, it promotes the formation of a conductive SEI layer rich in LiF and LiH, which contributes to an extended ...

First whole genome sequence of a diploid crop wild relative of the Andean tuber “oca”: Annotation and comparative genomic analysis of Oxalis oulophora

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Oxalis oulophora, a diploid species closely related to the octoploid Andean tuber crop oca (Oxalis tuberosa), was selected for whole‐genome sequencing to aid in understanding the origins of polyploidy and domestication in oca and its relatives (crop wild relatives).

Supernova Remnants [PDF]

Highlights of Astronomy, 1974
AbstractThe present structure and recent changes in Cas A are discussed. On the deepest available exposures the optical remnant of this supernova is seen to consist of an almost complete shell. The southern part of this shell is outlined by knots that have developed during the last decade.

Optimized ACE2‐Fc fusion proteins with picomolar neutralization activity against highly evolved SARS‐CoV‐2 variants

Protein Science, Volume 35, Issue 2, February 2026.
Abstract The rapid evolution of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) has compromised the efficacy of many authorized monoclonal antibody products. This highlights the need for alternative strategies, especially for vulnerable populations such as immunocompromised individuals.
