Organic Analytical Reagents for the Determination of Inorganic Cations

June 22, 2012
Author(s)
Thomas J. Bruno, Paris D. Svoronos
The table entitled Organic Analytical Reagents for the Determination of Inorganic Substances, by G. Ackermann, L. Sommer, and D. Thorburn Burns, has been revamped and considerably expanded for this edition. The many recent advancements in this area have

Preparation of Special Analytical Reagents

June 22, 2012
Author(s)
Thomas J. Bruno, Paris D. Svoronos
This listing of analytical reagents has been updated to include formulations based on more recent experience, and also safety notes. In the absence of specific cautions, the user must observe sound laboratory practice and housekeeping to avoid exposure and

Properties of Common Cross-Linked Silicone Stationary Phases

June 22, 2012
Author(s)
Thomas J. Bruno, Paris D. Svoronos
Modern gas chromatography is most often performed with high efficiency capillary (open tubular) columns coated with a cross linked polymeric stationary phase. We provide chromatographic data on the two most common cross-linked phases [1]. The retention

Properties of Important NMR Nuclei

June 22, 2012
Author(s)
Thomas J. Bruno, Paris D. Svoronos
The following table lists the magnetic properties at higher field strengths required for choosing the nuclei to be used in NMR experiments [1-15]. The reader is referred to several excellent texts and the literature for guidelines in nucleus selection. For

Proton NMR Absorption of Major Chemical Families

June 22, 2012
Author(s)
Thomas J. Bruno, Paris D. Svoronos
The following table gives the region of the expected nuclear magnetic resonance absorptions of hydrocarbon families. These absorptions are reported in the dimensionless units of parts per million (ppm) versus the standard compound tetramethylsilane (TMS

Solid-Phase Microextraction Sorbents

June 22, 2012
Author(s)
Thomas J. Bruno, Paris D. Svoronos
While trapping sorbents have been used for many years in headspace analysis (most commonly with gas chromatography), the modern techniques of solid phase microanalysis (SPME) are particularly applicable to survey analyses [1]. In the following tables, we

Standards for Laboratory Weights

June 22, 2012
Author(s)
Thomas J. Bruno, Paris D. Svoronos
The following table provides a summary of the requirements for metric weights and mass standards commonly used in chemical analysis1-3. The actual specifications are under the jurisdiction of ASTM Committee E-41 on General Laboratory Apparatus and are the

Wavelength-Wavenumber Conversion Table

June 22, 2012
Author(s)
Thomas J. Bruno, Paris D. Svoronos
The following table provides a conversion between wavelength and wavenumber units, for use in infrared spectrophotometry [1]. Since spectra are presented in different formats, this table is an aid in interpretation.

Out-of-plane electrochemical transport in all-thin-film hetero-epitaxial solid oxide fuel cell structures

June 6, 2025
Author(s)
Huairuo Zhang, Albert Davydov, Yangang Liang, Xiaohang Zhang, Yaoyu Ren, Seunghun Lee, H.M. Jaim, Eric Marksz, Takeuchi Ichiro, Haiyan Tan, Leonid Bendersky, Chris Kucharczyk, Ruiyun Huang, Sossina Haile
We have fabricated all-thin-film solid oxide fuel cell (SOFC) heterostructures and investigated the transport properties of Sm0.2Ce0.8O2-δ (SDC20) in an out-of-plane measurement geometry. The SOFC heterostructures, consisting of a bottom SrRuO3 (SRO) or
