Optical constants of MgxZn1-xO

open access: yes
Optical constants of Mg(x)Zn(1-x)O films are measured by spectroscopic ellipsometry (M-2000U, J.A. Woollam Co.), where the Mg(x)Zn(1-x)O films are grown on Zn-polar ZnO (0001) substrates by molecular beam epitaxy. Ellipsometric parameters are measured at

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Understanding the logical constants and dispositions [PDF]

open access: yes, 2009
Many philosophers claim that understanding a logical constant (e.g. ‘if, then’) fundamentally consists in having dispositions to infer according to the logical rules (e.g. Modus Ponens) that fix its meaning.

Low‐Temperature Imidization of Polyimides (PI) for Scalable Manufacturing of Flexible Wearable Electronics

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐temperature imidization of PEG‐modified polyimide enables fully screen‐printed, roll‐to‐roll fabrication of flexible electrodes on PET substrates, delivering robust mechanical durability and reliable ECG/EMG signal performance for wearable electronics.

Binding of cadmium to soil humic acid as a function of carboxyl group content

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2010
The binding of Cd(II) to soil humic acid (HA) at pH 6.5 and in 0.1 mol/L KNO3 ionic medium, was studied by potentiometric titration with a cadmium ion selective electrode.

Accurate Determination of Optical Constants of Amorphous Absorbing Thin Films by Spectroscopic Ellipsometry

open access: yes, 2015
Spectroscopic ellipsometry (SE) and spectrophotometer are used to measure the ellipsometric parameters (psi and △) and transmittance of ultrathin diamond like carbon (DLC) film and amorphous silicon (a-Si) film respectively.

When spectroscopy fails: The measurement of ion pairing [PDF]

open access: yes, 2005
Spectroscopic techniques such as UV/vis, NMR, and Raman are powerful tools for the investigation of chemical speciation in solution. However, it is not widely recognized that such techniques do not always provide reliable information about ion ...
