High photoreactivity of chromophoric dissolved organic matter derived from Ulva prolifera and Sargassum

open access: yesFrontiers in Marine Science
The epipelagic macroalgae of Ulva prolifera and Sargassum are the primary contributors to widespread seaweed tides globally. Both ocean plants release large amounts of chromophoric dissolved organic matter (CDOM) into the surrounding seawater.

Impact of population growth on Carbon Dioxide (CO2) emission: empirical evidence from Nigeria

open access: yesJurnal Perspektif Pembiayaan dan Pembangunan Daerah, 2019
This paper seeks to examine the impact of population growth on carbon dioxide emission in Nigeria. Time series data from 1975 to 2016 was adopted. Variables such as population, affluence and technology were used as independent variables which were ...

Biochar mitigation potential in Norway estimated by IPCC Tier 1 and Tier 2 methods

open access: yesCarbon Management
Biochar is a recalcitrant carbon-rich solid produced by pyrolysis of organic residues, and its application to soil is considered a promising approach to mitigate climate change, as biochar resists decomposition to readily contributes to soil carbon (C ...

Review of the studies on emission evaluation approaches for operating vehicles

open access: yesJournal of Traffic and Transportation Engineering (English ed. Online), 2021
With the increasing international consensus concerning the negative effects of climate change, reducing greenhouse gases has become a higher priority in government policies and research committees. The transportation sector generates approximately 29% of

Incentivising and Accounting for Negative Emission Technologies

open access: yesEnergy Procedia, 2014
AbstractUnlike conventional greenhouse gas abatement technologies, which generally only eliminate or reduce emissions towards zero, negative emission technologies are able to remove CO2 from the atmosphere. One such technology is the application of carbon capture and storage (CCS) to biogenic CO2 sources (bio-CCS), such as those arising from biomass ...

The Impacts of Freight Trade on Carbon Emission Efficiency: Evidence from the Countries along the “Belt and Road”

open access: yesComplexity, 2020
Extensive research has been carried out on the “Belt and Road” initiative, most of it focusing on geographical economy and international trade. However, there is a lack of research on the carbon emissions efficiency of the countries along the “Belt and ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Impact of Basalt Rock Powder on Ryegrass Growth and Nutrition on Sandy and Loamy Acid Soils

open access: yesAgronomy
Enhanced weathering of silicate rocks in agriculture is an option for atmospheric CO2 removal and fertility improvement. The objective of our work is to characterise some of the agricultural consequences of a basaltic powder amendment on soil-crop ...
