Sentences with phrase «electrode surface»

The devices worked, but they generated just 200 milliwatts of power per square centimeter (mW / cm2) of electrode surface area, well behind the performance of PEM fuel cells and SOFCs.

The PBCTF is limited to membrane electrode assemblies with electrode surface area of approximately 1 cm2 with membrane surface area up to 5 cm2.

Dendrites - deposits that form on electrode surfaces during the charging process - cause the batteries to short circuit, leading to serious safety hazards.

Electrocatalytic Reduction of CO2 on Cu and A / W Electrode Surfaces: Empirical Confirmation of Computational (DFT) Predictions A. Javier, J. H. Baricuatro, Y. G. Kim, and M. P. Soriaga

However, metal electrode surfaces can cause a region of the vacuum to become conductive by injecting free electrons or ions through either field emission or thermionic emission.

(Invited) Regulating the CO-Reduction Product Distribution by the Atomic - Level Structural Modification of the Cu Electrode Surface Y. G. Kim, J. H. Baricuatro, A. Javier, and M. P. Soriaga

This interface impacts areas as diverse as prolonging lithium - ion battery life, designing catalytic reactions that can convert biomass to biofuels, and extracellular electron transfer in microbial communities where bacteria catalyze electrode surfaces and shuttle electrons externally, as in a microbial fuel cell.

According to the company, «GridShift's new method for hydrogen generation produces four times more hydrogen per electrode surface area than what is currently reported for commercial units today.

Alnald Javier, «Reduction of CO2 on Cu and Au / W Electrode Surfaces: A Study by Differential Electrochemical Mass Spectrometry» (Poster Presentation)

As control elements distribute the fuel over one electrode surface, the other receives air.

While coating the electrode surface with a thin layer of carbon or graphene had been shown to improve performance, there was no microscopic and quantitative understanding of why this made a difference, Bazant says.

This hydrophobic coating expels water molecules from the vicinity of the electrode surface and then, upon charging for the first time, decomposes and forms a stable interphase — a thin mixture of breakdown products that separates the solid anode from the liquid electrolyte.

These electrode surfaces are coated with what are known as Faradaic materials, which can undergo reactions to become positively or negatively charged.

Why It Matters: The device provides a way to understand the basic breakdown reactions, material build - up, and other processes at the electrode surface during operation.

When the soft - landed clusters diffuse through the extremely thin membrane and reach the electrode surface of the newly designed device, the team has a detailed and precisely defined active species they can examine using several electrochemical and spectroscopic techniques.

An optimal enzyme system would directly transfer electrons captured from a chemical reaction to an electrode surface — ideally, to use enzymes immobilized on the surface of an electrode.
