Effect of Corrosion on the High Cycle Fatigue Strength of Martensitic Stainless Steel X12CrNiMoV12-3 [PDF]

open access: yes, 2012
This paper addresses the effects of corrosion on the high cycle fatigue (HCF) strength of a high mechanical strength martensitic stainless steel (X12CrNiMoV12-3) that is used in aeronautic applications. HCF tests (between 105 and 107 cycles) were carried

A Preview of EI and EI

open access: yesSocial Science Computer Review, 1996
Ecological inference, as traditionally defined, is the process of using aggregate (i.e., ecological) data to infer discrete individual-level relationships of interest when individual-level data are not available. Existing methods of ecological inference generate very inaccurate conclusions about the empirical world- which thus gives rise to the ...

A label free electrochemical nanobiosensor study [PDF]

open access: yes, 2009
Nano-porous silicon (PS) is an attractive material for incorporation into biosensors, because it has a large surface area combined with the ability to generate both optical and electrical signals. In this paper, we describe a label-free nanobiosensor for

Electrochemical and molecular simulation studies on the corrosion inhibition of L-glutamine monolayers on an iron surface [PDF]

open access: yesJournal of the Serbian Chemical Society, 2009
L-Glutamine was used to form monolayers for the inhibition of the corrosion of iron in 0.50 mol dm-3 H2SO4. The protection ability of the films was examined by electrochemical impedance spectroscopy. The mechanism of adsorption is discussed using quantum

Evaluation of Corrosion inhibition properties of pharmaceutically active compound Cefotaxime sodium on mild steel surface in sulfuric acid medium

open access: yesJournal of the Turkish Chemical Society, Section A: Chemistry, 2021
Cefotaxime sodium is applied in various concentrations in 0.5M sulphuric acid towards the mild steel and analyzed through weight loss, potentiodynamic polarization and EIS studies at 298 to 338oK.

How to Model the Near-to-the-Carrier Regime and the Lower Knee Frequency of Real RF Oscillators

open access: yesJournal of Electrical and Computer Engineering, 2010
Numerous empirical data demonstrate that real noisy RF oscillators are affected by power-law phase noise. However, until recently, the robust analytic modeling of the deep-into-the-carrier spectral regime of RF oscillators was intangible due to the ...

Inhibition behaviour of mild steel by three new benzaldehyde thiosemicarbazone derivatives in 0.5 M H2SO4: experimental and computational study [PDF]

open access: yesRoyal Society Open Science, 2019
Three new benzaldehyde thiosemicarbazone derivatives namely benzaldehyde thiosemicarbazone (BST), 4-carboxyl benzaldehyde thiosemicarbazone (PBST) and 2-carboxyl benzaldehyde thiosemicarbazone (OCT) were synthesized and their inhibition effects on mild ...

Layer formation by 1,7-diphosphono-heptane [PDF]

open access: yesJournal of the Serbian Chemical Society, 2001
Surface modification of polycrystalline ARMCO iron and an Fe(110) single crystal was performed using a solution of 1,7-diphosphono-heptane (DPH). The changes of the surface properties were studied by subtractively normalised interfacial Fourier ...
