Effect of contaminations and surface preparation on the work function of single layer MoS2

open access: yesBeilstein Journal of Nanotechnology, 2014
Thinning out MoS2 crystals to atomically thin layers results in the transition from an indirect to a direct bandgap material. This makes single layer MoS2 an exciting new material for electronic devices.

Modulation of phospholipase A2 by electrostatic fields and dipole potential of glycosphingolipids in monolayers

open access: yesJournal of Lipid Research, 1999
Phospholipase A2 activity against mixed monolayers of dilauroylphosphatidic acid or dilauroylphosphatidylcholine with glycosphingolipids can be reversibly modulated by external constant electrostatic fields.

Phase transition induced recrystallization and low surface potential barrier leading to 10.91%-efficient CsPbBr3 perovskite solar cells

open access: yesNano Energy, 2019
High efficiency and long-term stability are vital for further development of perovskite solar cells (PSCs). PSCs based on cesium lead halide perovskites exhibit better stability but lower power conversion efficiencies (PCEs), compared with organic ...

Effect of Pre-passivation on the Corrosion Behavior of PH13-8Mo Stainless Steel in Industrial—Marine Atmospheric Environment

open access: yesFrontiers in Materials, 2019
The corrosion behavior and mechanism of PH13-8Mo stainless steel with and without nitric acid passivated film were studied through 5 years of outdoor exposure tests in industry-marine atmospheric environments in Qingdao, by means of morphological ...

Electrochemical Perspective on Hematite–Malonate Interactions

open access: yesColloids and Interfaces, 2021
Organic matter (OM) interactions with minerals are essential in OM preservation against decomposition in the environment. Here, by combining potentiometric and electrophoretic measurements, we probed the mode of coordination and the role of pH-dependent ...

Fluorocholesterols, in contrast to hydroxycholesterols, exhibit interfacial properties similar to cholesterol

open access: yesJournal of Lipid Research, 2000
We used an automated Langmuir-Pockels surface balance to characterize the air–water interfacial properties of cholesterol (CH) and its derivatives with hydrophilic OH and F substitutions at isologous sites on the sterol body or side chain.
