The influence of iron-binding ligands in the corrosion of carbon steel driven by iron-reducing bacteria

npj Materials Degradation, 2022
Iron reducing bacteria (IRB) are thought to accelerate the corrosion of steel by removing the Fe(III)-oxide passivating layer through iron respiration.

Citrate and malonate increase microbial activity and alter microbial community composition in uncontaminated and diesel-contaminated soil microcosms

, 2016
. Petroleum hydrocarbons (PHCs) are among the most prevalent sources of environmental contamination. It has been hypothesized that plant root exudation of low molecular weight organic acid anions (carboxylates) may aid degradation of PHCs by stimulating ...

Malonate induces the assembly of cytoplasmic stress granules

FEBS Letters, 2016
Malonate, a classic inhibitor of respiratory electron transport chain, induces mitochondrial stress. Stress granules (SGs) are a kind of dynamic foci structure during stress.

Decentralised Learning MACs for Collision-free Access in WLANs [PDF]

Springer Wireless Networks 2013, Volume 19, Issue 1, pp 83-98, 2010
By combining the features of CSMA and TDMA, fully decentralised WLAN MAC schemes have recently been proposed that converge to collision-free schedules. In this paper we describe a MAC with optimal long-run throughput that is almost decentralised. We then design two \changed{schemes} that are practically realisable, decentralised approximations of this ...

Palladium catalyzed asymmetric hydrophosphination of α,β- and α,β,γ,δ-unsaturated malonate esters - efficient control of reactivity, stereo- and regio-selectivity.

Dalton Transactions, 2015
Both PC-cyclometalated and PCP-pincer type palladium catalysts have recently been found to be robust and efficacious catalysts for the asymmetric P-H addition reaction involving activated olefins.

Synthesis of New C2- Symmetric Fluoren-9-ylidene Malonate Derived Bis(oxazoline) Ligands and Their Application in Friedel-Crafts Reactions

Molecules, 2010
A series of new C2-symmetric fluoren-9-ylidene malonate-derived bis(oxazoline) ligands were synthesized from fluoren-9-ylidene malonate and enantiomerically pure amino alcohols via a convenient route.

Mice Deficient in Cellular Glutathione Peroxidase Show Increased Vulnerability to Malonate, 3-Nitropropionic Acid, and 1-Methyl-4-Phenyl-1,2,5,6-Tetrahydropyridine

Journal of Neuroscience, 2000
Glutathione peroxidase (GSHPx) is a critical intracellular enzyme involved in detoxification of hydrogen peroxide (H2O2) to water. In the present study we examined the susceptibility of mice with a disruption of the glutathione peroxidase gene to the ...
