An updated protocol based on CLSI document C37 for preparation of off-the-clot serum from individual units for use alone or to prepare commutable pooled serum reference materials

October 30, 2019
Author(s)
Johanna Camara, Uliana Danilenko, Hubert W. Vesper, Gary L. Myers, Patric A. Clapshaw, W. Greg Miller
Manufacturers of in-vitro diagnostic medical devices, clinical laboratories, research laboratories and calibration laboratories require commutable reference materials that can be used in the calibration hierarchies of medical laboratory measurement

Unusual Regularity in GC Retention of Simple Amino Acid Derivatives

August 8, 2019
Author(s)
Anzor I. Mikaia, Nino G. Todua, Zenkevich G. Igor
Background. Application of simple regularities and the general principles along with direct use of reference retention index data is a useful approach for reliable structure determination of compounds by GC-MS. Objective. Interpretation of anomaly in

Enzyme-Inspired Microporous Polymer Layers Determine the Reactivity of Encapsulated Metallic Surfaces

August 5, 2019
Author(s)
Andrew Herzing, Andrew Riscoe, Cody Wrasman, Adam Hoffman, Aditya Menon, Alexey Boubnov, Maria Vargas, Simon Bare, Matteo Cargnello
Enzymes are natural catalysts that govern precise, biological chemistry through accurate control of transport and activation of species within three-dimensional active sites, but their use in industrial applications is limited by their stability1

Stability of gaseous volatile organic compounds contained in gas cylinders with different internal wall treatments

July 29, 2019
Author(s)
George C. Rhoderick, Christina Cecelski, Walter R. Miller Jr., David Worton, Sergi Moreno, Paul Brewer, Joele Viallon, Faraz Idrees, Philippe Moussay, Yong D. Kim, Dal H. Kim, Sangil Lee, Annarita Baldan, Jianrong Li
Volatile organic compounds (VOCs) are a group of gas-phase compounds present in the atmosphere that affect air quality and Earth's climate. Halocarbons, a subset of this group, are strong greenhouse gases and are linked to stratospheric ozone depletion

Precision, Tunable Deuterated Polyethylene via Polyhomologation

July 22, 2019
Author(s)
Wesley Farrell, Sara Orski, Anthony Kotula, Kathryn Beers, Daniel Baugh
Polyhomologation (also known as "C1 polymerization") of a deuterated ylide has been performed, which yields linear polyethylene of high deuterium content. Copolymerization with the protonated analog allows for the preparation of sta-tistical copolymers, in
