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

Effect of Flexibility and Nanotriboelectrification on the Dynamic Reversibility of Water Intrusion into Nanopores: Pressure-Transmitting Fluid with Frequency-Depending Dissipation Capability

October 30, 2019
Author(s)
Alexander Lowe, Nikolay Tsyrin, Miroslaw Chorazewski, Pawel Zajdel, Michal Mierzwa, Juscelino Leao, Markus Bleuel, Tong Feng, Dong Luo, Mian Li, Dan Li, Victor Stoudenets, Sebastian Pawlus, Abdessamad Faik, Yaroslav Grosu
In this work the effect of a porous material´s flexibility on the dynamic reversibility of a non-wetting liquid intrusion was explored experimentally. For this purpose, high-pressure water intrusion together with high-pressure in-situ small angle neutron

Fernandes, Masahiko Numata, Ha-Jeong Kwon, Ji-Seon Jeong, Bei Xu, Jintana Nammoommoy, Dewei Song, Wagner Wollinger
Over two decades, the Organic Analysis Working Group (OAWG) of the Consultative Committee for Amount of Substance (CCQM) has organised a number of comparisons for clinically relevant small molecule organic biomarkers. These comparisons are hinged upon the

Measurement of mass of aerosol particles

October 30, 2019
Author(s)
Kevin J. Coakley, Robert C. Hagwood, Kensei Ehara, Nobuhiko Fukushima, Kittichote Worachotekamjorn, Naoko Tajima, Hiromu Sakurai
An aerosol particle mass analyzer (APM) which classifies aerosol particles according to their mass has been developed. Mass distributions of aerosol particles can be measured by the APM combined with a particle counting device. Particle mass that can be

Optical-Clock-Based Time Scale
