A Note on Solid-State Maxwell Demon [PDF]

open access: yes, 2004
Starting from 2002, at least two kinds of laboratory-testable, solid-state Maxwell demons have been proposed that utilize the electric field energy of an open-gap n-p junction and that seem to challenge the validity of the Second Law of Thermodynamics ...

Study of Corrosion Behavior of a 2507 Super Duplex Stainless Steel: Influence of Quenched-in and Isothermal Nitrides

open access: yesInternational Journal of Electrochemical Science, 2014
Precipitation of different types of chromium nitrides may occur during processing of super duplex stainless steels, affecting the properties of the material. In this study the influence of quenched-in (size range ca. 50-100 nm) and isothermal (size range

Thermodynamics of Thermoelectric Phenomena and Applications [PDF]

open access: yes, 2011
Fifty years ago, the optimization of thermoelectric devices was analyzed by considering the relation between optimal performances and local entropy production. Entropy is produced by the irreversible processes in thermoelectric devices.

Estimating the stochastic uncertainty in sample-based estimates of infant mortality in Ghana [PDF]

open access: yes, 2020
The Infant Mortality Rate (IMR) is an important population health statistic often used as one of the indicators of the health status of a nation. In many countries lacking adequate vital registration systems, sample methods are used to estimate IMRs ...

Improving the Relative Calculations of Volta Potential Differences Acquired from Scanning Kelvin Probe Force Microscopy (SKPFM) from Comparing an Inert Material to First-Principle Calculations

open access: yesECS Transactions, 2018
An improved relative scaling of Volta potential differences (VPD) acquired from scanning Kelvin probe force microscopy (SKPFM) was developed by quantifying the probe work function. In corrosion studies, SKPFM has been used to identify local nobility of complex metallic systems and provide theoretical corrosion initiation sites.

In-situ AFM and quasi-in-situ studies for localized corrosion in Mg-9Al-1Fe-(Gd) alloys under 3.5 wt.% NaCl environment

open access: yesJournal of Magnesium and Alloys
Revealing the localized corrosion process of Mg alloy is considered as one of the most significant ways for improving its corrosion resistance. The reliable monitor should be high distinguishability and real-time in liquid environment. Herein, Mg-9Al-1Fe

Sub-Microscopic Phenomena of Metallic Corrosion Studied by a Combined Photoelectron Spectroscopy in Air (PESA) and Scanning Kelvin Probe Force Microscopy (SKPFM) Approach

open access: yesInternational Journal of Electrochemical Science, 2012
The management of metallic corrosion has relied on large-scale, ultra-conservative protection strategies such as the extensive use of anti-corrosion metals and alloys, all-inclusive coating and surface passivation, and substantial use cathodic protection.
