John Jeyes Award 2014

Professor Vicki Grassian, Chair of Environmental Science: Nano was awarded the John Jeyes Award 2014 this week for her pioneering contributions to the chemistry of environmental interfaces, heterogeneous atmospheric chemistry and the environmental implications of nanomaterials.

The John Jeyes Award, founded in 1975, is a biennial award for chemistry in relation to the environment. John Jeyes was a prolific inventor and scientist who in 1877 invented one of the first disinfectants, which is still used today. This is one of the six awards and prizes that are given by the Environment, Sustainability and Energy Division of the Royal Society of Chemistry.

Vicki Grassian, Founding Director of the Nanoscience and Nanotechnology Institute at the University of Iowa, has mentored over one hundred students and postdocs in her laboratory with many of them now having their own research programs focused on energy and the environment and developed the chemical sciences track of the undergraduate degree program in environmental science.


“The John Jeyes Award is wonderful recognition of the research that has been done by the students and postdoctoral associates who have worked in my laboratory”


We would like to congratulate Vicki on her achievement and take this opportunity to thank her for her pioneering contributions to Environmental Science: Nano , bringing together a variety of communities to publish their work on nanoscience and the implications for the environment, health and sustainability.

Vicki’s latest Environmental Science: Nano paper ‘Iron oxide nanoparticles induce Pseudomonas aeruginosa growth, induce biofilm formation and inhibit antimicrobial peptide function‘ (C3EN00029J) is included in a dedicated themed collection of papers celebrating the 2014 RSC Prize and Award winners.


Each year the Royal Society of Chemistry gives out over 60 awards and prizes that recognise excellence in the chemical sciences. Our 2015 awards and prizes are open for nomination now, why not nominate someone today?

Nanoceria biodistribution and retention

Nanoceria (nanoparticle form of CeO2, cerium(IV) oxide) is quickly becoming a trending topic in Environmental Science. After recently discussing its health effects, today we present a fascinating paper regarding its biodistribution and retention in rats.

Currently, the main use for nanoceria is as an abrasive catalyst, especially important for the industry in silicon integrated circuit fabrication. In addition to that, and thanks to its autocatalytic behaviour, encouraging results have been presented in the past regarding its use as an antineoplastic agent. Nevertheless, there is concern on the topic of its toxicity in organisms.

Dr Robert A. Yokel and colleagues from the University of Kentucky have conducted an extensive investigation on the distribution and retention of several nanocerias after their systemic administration to rats.

The aim of their study was to determine if and how the biodistribution and persistence of nanocerias are modified according to the doses administered.

Additionally, interesting discussions regarding nanoceria shape and its influence on its toxicity, retention and disposition have been presented.

Moving forward, it will be exceptionally exciting to learn more about nanoceria’s clinical properties and effects on animals. In any case, this work is a big step forward in its research, helping us to clarify and consolidate our knowledge of the behaviour of nanocerias in mammalian organisms.

Nanoceria biodistribution and retention in the rat after its intravenous administration are not greatly influenced by dosing schedule, dose, or particle shape
Robert A. Yokel, Jason M. Unrine, Peng Wu, Binghui Wang and Eric A. Grulke
Environ. Sci.: Nano, 2014, Advance Article
DOI: 10.1039/C4EN00035H

The paper mentioned today is part of our Nanoceria Research themed collection, which is the most comprehensive and current source of information on the chemistry, biology, and beneficial and untoward effects of nanocerias.
