Gradient of Potential near Electrodes
Nature, 1923IN NATURE of March 31, p. 431, Messrs. H. Nagaoka and Y. Sugiura describe a method of observing the Stark effect in the iron arc; namely, in the thin layer at the surface of the lower electrode. This fact points to the existence of a considerable gradient of potential in this layer.

Extended Potential-Gradient Architecture of a Phenylazomethine Dendrimer
Organic Letters, 2013A dendritic nanoshell based on rigid phenylazomethine units was synthesized up to fifth generation around a zinc porphyrin core. Due to the finely organized sparse architecture, accessibility to the core can be discriminated by the size of the molecules and ionic species.

Potential Gradient and Atmospheric Pollution
Nature, 1924RECENT correspondence (NATURE, April 5 and June 14) on the connexion between the potential gradient and the degree of pollution of the atmosphere prompts me to put forward a suggestion to explain the alleged influence of a high-tension electric field on plant growth.

Atrial gradient as a potential predictor of atrial fibrillation
Heart Rhythm, 2005We tested the utility and comparability of the atrial gradient and atrial ERP as early markers of electrical remodeling and a propensity to atrial fibrillation (AF).Pacing at physiologic rates from the left atrium alters the atrial gradient and is associated with atrial tachyarrhythmias.

Maxima of potential gradient at Apia
Terrestrial Magnetism and Atmospheric Electricity, 1936The average values of potential gradient of the atmosphere between successive hourly periods 0h–1h, 1h–2h, 23h–24h, on complete days free from negative potential during the period 1924–34 have been tabulated and the means of these average values for each year are given in Table 1. The departures of the hourly means from the daily mean have been plotted

Orographic effect on potential gradient
pure and applied geophysics, 1984Potential gradients were measured in the valley of the Simhachalam hills and near the top. They were found to be higher at the top than in the valley, where they increased in the forenoon. It was the reverse at the top of the hills. The valley winds were found to play an important role in the variation of potential gradient.

Potential gradient as a predictor of fog
Although fog is an important weather phenomenon, it remains difficult to predict using traditional methods. This could be improved by new observations-based nowcasting systems. It has long been understood that fog affects measurements of atmospheric electricity.Caleb Miller +3 more

Transport in Chemical Potential Gradients of Multicomponent Oxides
Annual Review of Materials Science, 1987The ultimate goal of the investigation of solid-state reactions in materials science is the understanding of the atomistic reaction mechanisms. There fore, all the complicated conditions at the phase boundaries and, conse quently, the complex phenomenological formalisms in any non-steady state only obscure the atomistic processes.
