Differential pulse voltammetry (DPV) and adsorptive stripping voltammetry (AdSV) at a hanging mercury drop electrode (HMDE) was used for the determination of trace amounts of carcinogenic nitrobiphenyls, namely 2-nitrobiphenyl (2-NBP), 3nitrobiphenyl (3-NBP) and 4-nitrobiphenyl (4-NBP) within the concentration range from 2.10 to 1.10 mol⋅L for DPV and from 2.10 to 1.10 mol⋅L for AdSV using a Br...

a statistical mechanical based equation of state has been employed to calculate the liquid density of lead, mercury, bismuth and lead-bismuth and lead-lithium eutectic alloys.the equation is basically that of song, mason and ihm [ihm g, song y, mason ea. j. chem. phys.1991; 94: 3839] which is modified by ghatee and boushehri. three temperature dependent parameters are required to use this equat...

A liquid metal embrittlement specificity of three austenitic steels with increasing nickel content (304L, 316L and 316L(N)) is studied in mercury. Only the low alloys are susceptible to LME. The crack path an steel fracture induced by mercury has been elucidated. Deformation martensite (γ → α’) induces numerous α’/α’ interfaces at small scale that be embrittled. Because only resists LME one sho...

Abstract Fins are extended surfaces to increase convection heat transfer. Conventional fins made of solid metals and alloys. Liquid such as sodium have melting points below atmospheric temperature. lower specific heats higher thermal diffusivity when compared metals. These properties can be used in enhancing In the present work, a numerical model is developed for analyzing effect capsulating li...

The synthetic formation of mercury thiolates has been known for almost 200 years. These compounds are usually formed by a slow reaction of mercury salts with thiolates or disulfides to produce small (up to 1 μm), plate-like crystals of Hg(S-R)(2). Herein we show that such mercury thiolates can be formed directly from liquid mercury via sonication with neat thiols. The process not only produces ...

The prominence of sulfate reducers in mercury biomethylation prompted the examination of the methyl carrier and mercury methylation activity of Desulfovibrio desulfuricans LS. There was a low degree of mercury tolerance and a high degree of methylation during fermentative growth; the opposite was true during sulfate reduction. During 2 days of fermentative growth, up to 37% of HgCl2 was methyla...

We optimized potential parameters in a molecular dynamics model to reproduce the experimental contact angle of a macroscopic mercury droplet on graphite. With the tuned potential, we studied the effects of pore size, geometry, and temperature on the wetting of mercury droplets confined in organic-rich shale nanopores. The contact angle of mercury in a circular pore increases exponentially as po...
