23-Jan-2018 | Arnab Mukherjee; Vincent A. Hackley, Analyst, 2018
Cellulose nanocrystals (CNCs) are renewable, naturally derived polymeric nanomaterials receiving substantial attention for a wide range of potential applications. The recent availability of high quality reference materials will facilitate the development and validation of measurement methods ...
23-Oct-2017 | Zhi-Qiang Tan; Yong-Guang Yin; Xiao-Ru Guo; Meseret Amde; Myeong Hee Moon; Jing-Fu Liu; Gui-Bin Jiang, Environmental Science & Technology, 2017
It is a great challenge to monitor the physical and chemical transformation of nanoparticles at environmentally relevant concentration levels, mainly because the commonly used techniques like dynamic light scattering and transmission electron microscopy are unable to characterize and quantify ...
14-Oct-2017 | Author(s): Valentina Marassi, Barbara Roda, Sonia Casolari, Simona Ortelli, Magda Blosi, Andrea Zattoni, ..., Microchemical Journal, 2017

13-Oct-2017 | Simona Sitar; Valerija Vezočnik; Peter Maček; Ksenija Kogej; David Pahovnik; Ema Žagar, Analytical Chemistry, 2017
An asymmetrical flow field-flow fractionation (AF4) technique coupled to a multiangle light scattering (MALS) detector with an embedded dynamic light scattering (DLS) module was introduced to study the size characteristics and shape of soft particles of various size and type: polystyrene ...
14-Jul-2017 | Chad W. Cuss; Iain Grant-Weaver; William Shotyk, Analytical Chemistry, 2017
The smallest colloids exert a disproportionately large influence on colloidal systems owing to their greater surface area; however, the challenges of working in the smaller size range have limited most field-flow fractionation-ICPMS analyses to sizes > ca. 1 kDa. We discuss considerations and ...
22-Jun-2017 | Upenyu L. Muza; Guilaume Greyling; Harald Pasch, Analytical Chemistry, 2017
Micelles prepared from amphiphilic block copolymers (ABCs) have found numerous applications in pharmaceutical, electronics, environmental, cosmetics, and hygiene industries. These micelles, whether in the pure or mixed micelle form, often exist as multiple morphologies (spherical, cylindrical, ...

A methodology has been developed to measure nanoparticle mass and density, by combining centrifugal field-flow fractionation (CeFFF; more commonly called sedimentation FFF or SdFFF) and transmission electron microscopy (TEM). Particle effective mass obtained from CeFFF retention data and particle ...
16-May-2017 | Sylvie Motellier; Nathalie Scheer-Pélissier; Jean-Gabriel Mattei, Journal of Analytical Atomic Spectrometry, 2017
The determination of the size and size distribution of five silver nano-colloid populations has been assessed by different techniques. Transmission electron microscopy (TEM) was proposed as a reference in single particle methods. It was compared with three particle population methods: dynamic ...
10-May-2017 | Heinrich Rübsam, Thomas Becker, Martina Gastl, Journal of Food Science, 2017
Abstract The changes on the molecular weight distribution (MWD) and particle size distribution (PSD) during hydrolysis of barley malt in isothermal mashing procedures were determined using asymmetrical flow field flow fractionation coupled to multiangle laser light scattering and refractive ...
