Putative Mechanisms for Initial Reaction of Anaerobic Benzene Degradation Presumably Involving a Flavoprotein

open access: yesEnvironmental Microbiology, Volume 28, Issue 8, August 2026.
Anaerobic biodegradation of benzene by sulphate‐reducing strain BzS1 was studied by combining genomics, differential proteomics and targeted metabolite analyses. Strain BzS1 has an exceptionally streamlined metabolism. A highly abundant heterotrimeric flavoprotein may add benzene to either enolpyruvate or glutaconyl‐CoA followed by channelling into the

Cultural geography of heat: Artistic experiments with heat’s animacies

open access: yesGeographical Research, Volume 64, Issue 3, August 2026.
A sustained, cultural geographical engagement with heat is long overdue. I advance this agenda by engaging with the work of contemporary artists. Artists are responding to uneven conditions of global heating by exploring heat’s animacies: how heat interweaves with the practices and textures of life.

Evaluating maturity of organic matter in hydrated C1 and CM‐like clasts and a dehydrated clast within a polymict eucrite and a howardite

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 8, Page 1965-1993, August 2026.
Abstract Volatile‐rich xenolithic clasts in different types of brecciated meteorites represent unique pristine solar system material. This study investigates the maturity and thermal history of organic matter using Raman spectroscopy and aqueous alteration effects using infrared spectroscopy in the matrix of 15 volatile‐rich clasts (C1 and CM‐like ...

Bed‐scale quantitative discrimination of hyperpycnites from intrabasinal turbidites—Results from a channelised slope system in the Upper Carboniferous Westward Ho! Formation, United Kingdom

open access: yesSedimentology, Volume 73, Issue 5, Page 1750-1798, August 2026.
ABSTRACT Features considered indicative of hyperpycnites and intrabasinal turbidites overlap. Outcrop study presented here suggests that the Westward Ho! Formation forms an 800 m high deepwater‐slope system dominated by hyperpycnites. Taking this unit, and other successions where hyperpycnites have been described, as having been deposited solely from ...

Local Variability of Ice Core Ammonium and Black Carbon Records From Tunu and Summit, Greenland: Implications for Long‐Term Biomass Burning Reconstructions

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Paleoclimate reconstructions of wildfire using ice cores often rely on high‐resolution aerosol records of refractory black carbon (rBC) or ammonium (NH4+). The interpretation of such records, however, can be hindered by uncertainties related to long‐range atmospheric transport, spatial distribution and strength of emissions, as well as ...

The ignitability of coal dust-air and methane-coal dust-air mixtures

Fuel, 1993
Abstract An experimental investigation of coal dust explosions was conducted in a 26 1 spherical chamber. Channel (mine-face) samples of coal from the Prince and Phalen mines of the Cape Breton Development Corporation were used. The objective of the work was to investigate the ignitability characteristics of the coals, alone and with admixed methane.

Synthesis of Coal Dust Depressor and its Application in Preventing Coal Dust

Advanced Materials Research, 2012
A novel coal dust depressor was prepared by alkalization and etherficayion reactions using wastepaper as raw material. The sample was characterized by means of FTIR spectroscopy (FTIR)、scanning electron microscopy (SEM)、X-ray diffraction (XRF) and viscometer measurements.

Coal-Dust

2009
Going home from school in the afternoon, the Brangwen girls descended the hill between the picturesque cottages of Willey Green till they came to the railway crossing. There they found the gate shut, because the colliery train was rumbling nearer.
