Water Splitting Reaction at Polar Lithium Niobate Surfaces [PDF]

, 2019
Water splitting is a highly promising, environmentally friendly approach for hydrogen production. It is often discussed in the context of carbon dioxide free combustion and storage of electrical energy after conversion to chemical energy.

Electro-oxidation of Ethanol on Carbon Supported PtSn and PtSnNi Catalysts [PDF]

, 2016
Even though platinum is known as an active electro-catalyst for ethanol oxidation at low temperatures (< 100 oC), choosing the electrode material for ethanol electro-oxidation is a crucial issue.

Disguised as a Sulfate Reducer: Growth of the Deltaproteobacterium Desulfurivibrio alkaliphilus by Sulfide Oxidation with Nitrate

mBio, 2017
This study demonstrates that the deltaproteobacterium Desulfurivibrio alkaliphilus can grow chemolithotrophically by coupling sulfide oxidation to the dissimilatory reduction of nitrate and nitrite to ammonium.

Methane oxidation linked to chlorite dismutation.

Frontiers in Microbiology, 2014
We examined the potential for CH4 oxidation to be coupled with oxygen derived from the dissimilatory reduction of perchlorate, chlorate or via chlorite (ClO2-) dismutation.

Nitrogen removal in marine environments: recent findings and future research challenges [PDF]

, 2005
Respiratory reduction of nitrate (denitrification) is recognized as the most important process converting biologically available (fixed) nitrogen to N2. In current N cycle models, a major proportion of global marine denitrification (50–70%) is assumed to
