volta metric behavior of mesotrione using silver/amalgam electrode we examined in this paper.mesotrione belongs to the triketone group of herbicides. it is used against weeds in corn and operates byinhibition of 4-hydroxyphenyl piruvate in plants. there is little information about mesotrione as its presencein the market is short. for its wider application in the future, it is important to know ...
The novel fixed (non-vibrating) Volta potential probe was evaluated in comparison with the standard, vibrating (400 Hz) commercial Kelvin probe. While both tested probes demonstrated the similar behavior, there were significant practical advantages of the novel probe. Specifically, the novel probe allows for the elevated distance to the surface and provides more sensitivity to charge under the ...
We describe a phase plate for transmission electron microscopy taking advantage of a hitherto-unknown phenomenon, namely a beam-induced Volta potential on the surface of a continuous thin film. The Volta potential is negative, indicating that it is not caused by beam-induced electrostatic charging. The film must be heated to ∼ 200 °C to prevent contamination and enable the Volta potential effec...
Alessandro Volta invented the electric battery at the end of 1799 and communicated his invention to the Royal Society of London in 1800. The studies that led him to develop this revolutionary device began in 1792, after Volta read the work of Luigi Galvani on the existence of an intrinsic electricity in living organisms. During these studies, Volta obtained a series of results of great physiolo...
The Xingu River is a large clearwater river in eastern Amazonia and its downstream sector, known as the Volta Grande do Xingu (“Xingu Great Bend”), is a unique fluvial landscape that plays an important role in the biodiversity, biogeochemistry and prehistoric and historic peopling of Amazonia. The sedimentary dynamics of the Xingu River in the Volta Grande and its downstream sector will be shif...
INTRODUCTION In 2016, Volta Region was one of the two regions in Ghana that recorded a high prevalence of teenage pregnancy, accounting for 15.5% of all adolescent pregnancies in the country. This study aimed to determine the prevalence of contraceptive methods accessed by person, place, and time in Volta Region, Ghana, 2009-2014. METHOD We carried out a secondary analysis of contraceptive us...
Abstract: Localized corrosion of aluminum alloys is often triggered by intermetallic particles, IMP’s. To understandthe role of IMP’s in corrosion initiation of EN AW-3003, efforts were made to combine nano-scale ex-situ analysis ofthe IMP’s by SEM-EDS, SKPFM and in-situ AFM monitoring of the localized attack in chloride containing solution.The results showed that two distinct types of eutectic...
