CVD Grown Tungsten Oxide for Low Temperature Hydrogen Sensing: Tuning Surface Characteristics via Materials Processing for Sensing Applications

open access: yesSmall, Volume 19, Issue 1, January 4, 2023., 2023
The implementation of new volatile heteroleptic W‐complex [W(NtBu)2(NiPr2)2] as precursor in a chemical vapor deposition (CVD) process enabled the growth of highly pure and crystalline WO3. Advanced surface characterization demonstrates that WO3 thin film implementation in a custom‐built mobile sensor device shows outstanding sensing response at low ...

Refueling the Magic Furnace: Kilonova 2017 Rewrites the Story of Element Origins

open access: yesJournal of Big History, 2018
For more than half a century, we have understood element creation in the stars—described in Marcus Chown’s colorful image as “the magic furnace.” From 1958 until 2017, supernova explosions were thought to be the primary site of element creation above ...

Historical Supernovae and Supernova Remnants [PDF]

open access: yesInternational Astronomical Union Colloquium, 1996
The oldest historical supernova (SN), recorded by ancient Chinese in 14th Century B.C. on pieces of tortoise shells or bones, is identified with the aid of modern space γ-ray observations. Hard X-rays with energy up to 20 keV were observed from IC 443 by the X-ray satellite Ginga. We infer from these observations the age of IC 443 is ∼ 1000 — 1400 yrs.

Neutrinos from Supernovas and Supernova Remnants [PDF]

open access: yesAIP Conference Proceedings, 2005
Supernovae (SN) and supernova remnants (SNR) have key roles in galaxies, but their physical descriptions is still incomplete. Thus, it is of interest to study neutrino radiation to understand SN and SNR better. We will discuss: (1) The ~10 MeV thermal neutrinos that arise from core collapse SN, that were observed for SN1987A, and can be seen with ...

Properties and Composition of Magnetized Nuclei

open access: yesParticles, 2020
The properties and mass distribution of the ultramagnetized atomic nuclei which arise in heavy-ion collisions and magnetar crusts, during Type II supernova explosions and neutron star mergers are analyzed.

Supernova Remnants and their Supernovae [PDF]

open access: yesInternational Astronomical Union Colloquium, 1988
AbstractObserving supernova remnants provides important clues to the nature of supernova explosions. Conversely, the late stages of stellar evolution and the mechanism of supernova explosions affect supernova remnants through circumstellar matter, stellar remnants, and nucleosynthesis. The elements of supernova classification and the connection between

Exploiting the molecular diversity of the synapse to investigate neuronal communication: A guide through the current toolkit

open access: yesEuropean Journal of Neuroscience, Volume 56, Issue 12, Page 6141-6161, December 2022., 2022
Chemical synapses are tiny and overcrowded environments enriched with thousands of protein species. Many efforts have been devoted to developing sensors and actuators able to evaluate and control synaptic communication. Most of these recent tools are based on the engineering of one or more specific synaptic proteins used to target active moieties to ...

Peculiar Supernovae [PDF]

open access: yesSpace Science Reviews, 2018
What makes a supernova truly `peculiar?' In this chapter we attempt to address this question by tracing the history of the use of `peculiar' as a descriptor of non-standard supernovae back to the original binary spectroscopic classification of Type I vs. Type II proposed by Minkowski (1941).

Historical Supernovae [PDF]

open access: yes, 2003
The available historical records of supernovae occurring in our own Galaxy over the past two thousand years are reviewed. These accounts include the well-recorded supernovae of AD 1604 (Kepler's SN), 1572 (Tycho's SN), 1181, 1054 (which produced the Crab Nebula) and 1006, together with less certain events dating back to AD 185.

Developmental transcriptomes predict adult social behaviours in the socially flexible sweat bee, Lasioglossum baleicum

open access: yesMolecular Ecology, EarlyView., 2023
Abstract Natural variation can provide important insights into the genetic and environmental factors that shape social behaviour and its evolution. The sweat bee, Lasioglossum baleicum, is a socially flexible bee capable of producing both solitary and eusocial nests.
