A Study on the Co-Combustion Characteristics of Coal and Bio-SRF in CFBC

Energies, 2023
Bio-SRF based on livestock waste has low heating value and high moisture content. The concentration of toxic gases such as SOx, NOx, and HCl in the flue gas is changed according to the composition of fuel, and it has been reported.

Surface-observation-constrained high-frequency coal mine methane emissions in Shanxi, China, reveal more emissions than inventories, consistent with satellite inversion [PDF]

Atmospheric Chemistry and Physics
This work focuses on Changzhi, Shanxi, China, a city and surrounding rural region with one of the highest atmospheric concentrations of methane (CH4) worldwide (campaign-wide minimum, mean, standard deviation, and max observations: 2.0, 2.9, 1.3, and 16 ...

Aminopropyl-Functionalized Silica CO2 Adsorbents via Sonochemical Methods

Journal of Chemistry, 2016
Aminopropyl-functionalized hexagonal mesoporous silica (HMS) products, as are of interest for CO2 capture applications, were separately prepared by mixing aminopropyltrimethoxysilane (APTS) and HMS in toluene via a conventional stirred reactor and via ...

Genome sequencing of rumen bacteria and archaea and its application to methane mitigation strategies

Animal, 2013
Ruminant-derived methane (CH4), a potent greenhouse gas, is a consequence of microbial fermentation in the digestive tract of livestock. Development of mitigation strategies to reduce CH4 emissions from farmed animals is currently the subject of both ...

A New Approach to Climate Change: A Consideration of Ancillary Benefits in Linking Regional Permit Trading Systems [PDF]

, 2015
In this paper, I investigate the economic efficiency of two major approaches to greenhouse gas reduction, and evaluate their respective benefits. First, I trace the path of action and thinking on addressing climate change from a global to a regional ...

Exploring Nasal Structural‐Microbial Interactions in Multiple Sclerosis‐Associated Olfactory Impairment

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Olfactory dysfunction is frequently observed in patients with multiple sclerosis (MS); however, its underlying mechanisms remain poorly understood. To date, no studies have directly examined the nasal mucosal microbiota in MS. This study aimed to explore potential relationships among olfactory function, nasal microbiota composition,

The implications of residential air conditioning refrigerant choice on future hydrofluorocarbon consumption in the United States

Journal of Integrative Environmental Sciences, 2020
As the primary alternative to ozone-depleting refrigerants, hydrofluorocarbons (HFCs) have increased in use and emissions in the United States. This increase, and a large portion of total U.S.
