Waste-Derived Renewable Hydrogen and Methane: Towards a Potential Energy Transition Solution

open access: yesFermentation, 2023
Anaerobic digestion (AD) is an environmentally friendly process for recovering low-carbon energy from the breakdown of organic substrates. In recent years, AD has undergone a major paradigm shift, and now the technology is not only considered as a “waste

Increased colonic propionate reduces anticipatory reward responses in the human striatum to high-energy foods [PDF]

open access: yes, 2016
Background: Short-chain fatty acids (SCFAs), metabolites produced through the microbial fermentation of nondigestible dietary components, have key roles in energy homeostasis.

Hydrogen-rich supernovae beyond the neutrino-driven core-collapse paradigm [PDF]

open access: yesNature Astronomy, 2017
We present our study of OGLE-2014-SN-073, one of the brightest Type II SN ever discovered, with an unusually broad lightcurve combined with high ejecta velocities. From our hydrodynamical modelling we infer a remarkable ejecta mass of $60^{+42}_{-16}$~M$_\odot$, and a relatively high explosion energy of $12.4^{+13.0}_{-5.9} \times10^{51}$~erg.

Nitric oxide and hydrogen sulfide: the gasotransmitter paradigm of the vascular system [PDF]

open access: yesBritish Journal of Pharmacology, 2017
There are several reviews on NO and hydrogen sulfide (H2S) and their role in vascular diseases in the current relevant literature. The aim of this review is to discuss, within the limits of present knowledge, the interconnection between these two gasotransmitters in vascular function.

Origin of Galactic Cosmic Rays [PDF]

open access: yes, 2012
The origin of the bulk of cosmic rays (CRs) observed at Earth is the topic of a century long investigation, paved with successes and failures. From the energetic point of view, supernova remnants (SNRs) remain the most plausible sources of CRs up to ...

Formation of fullerenes in H-containing Planetary Nebulae

open access: yes, 2010
Hydrogen depleted environments are considered an essential requirement for the formation of fullerenes. The recent detection of C60 and C70 fullerenes in what was interpreted as the hydrogen-poor inner region of a post-final helium shell flash Planetary ...

Supernova Feedback Keeps Galaxies Simple

open access: yes, 2011
Galaxies evolve continuously under the influence of self-gravity, rotation, accretion, mergers and feedback. The currently favored cold dark matter cosmological framework, suggests a hierarchical process of galaxy formation, wherein the present ...
