A Model for the Passivation of the Zinc Electrode in Alkaline Electrolyte [PDF]

, 2010
We have developed a model for the anodic dissolution and passivation of the zinc electrode in alkaline electrolyte. The model is based on postulated elementary reactions. Species on the electrode surface are assumed to follow Langmuir behavior.

Defect Passivation by Pyridine-Carbazole Molecules for Efficient and Stable Perovskite Solar Cells

, 2022
The defects in the light-harvesting perovskite absorber layer play a key role in limiting power conversion efficiencies (PCEs) and long-term stability of lead halide perovskite solar cells (PSCs).

Understanding of Molecular Contribution of Quinhydrone/Methanol Organic Passivation for Improved Minority Carrier Lifetime on Nanostructured Silicon Surface

Applied Sciences, 2019
In this report, we present a study of the quinhydrone/methanol (QHY/MeOH) organic passivation technique for a silicon (Si) surface. The roles of p-benzoquinone (BQ) and hydroquinone (HQ), which make up QHY, in controlling the uniformity and coverage of ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Increased amplification efficiency of microchip-based PCR by dynamic surface passivation

BioTechniques, 2004
Surface passivation is critical for effective PCR using silicon-glass chips. We tested a dynamic polymer-based surface passivation method. Polyethylene glycol 8000 (PEG 8000) or polyvinylpyrrolidone 40 (PVP-40) applied at 0.75% (w/v) in the reaction ...

Understanding the Sidewall Passivation Effects in AlGaInP/GaInP Micro-LED

Nanoscale Research Letters, 2022
The passivation effects of sulfur treatment and Al2O3 passivation for AlGaInP/GaInP red micro-light-emitting-diodes (LEDs) were investigated in terms of the external quantum efficiency (EQE) and the current density showing the peak EQE (J EQE, peak).

Electrochemical oxidation of binary copper-nickel alloys in cryolite melts [PDF]

, 2007
Anodic oxidation of copper, nickel and two copper-nickel alloys was studied in cryolite melts at 1000°C. In an oxide-free melt, anodic dissolution of each material was observed, and the dissolution potential increases with the content of copper.
