Scientific Newsletter
ISSUE I, 2015

 


EDITORIAL
Paul Wynne, iia Director

The International Irradiation Association (iia) is very proud to have amongst its members many leading universities, institutes and laboratories that are involved in radiation and polymer science. 

 

Whilst the existing iia newsletter provides updates on a range of industry topics it does not focus on scientific developments or research. The scientific newsletter is part of a number of initiatives that we are planning in order to highlight scientific research and education. The newsletter is not intended to compete with scientific journals where peer reviewed papers are published. The newsletter is intended to highlight the work of iia member institutes and universities and to bring this work to the attention of the widest possible audience.

  

The development of the scientific newsletter is being spearheaded by Gustavo Varca who is a post doctoral student (IPEN-CNEN/SP). Gustavo was a recipient of a iia Scientific Award at IRaP 2012 (Poland) and was part of the awards committee at IRaP 2014 (Korea) which selected winners of the most recent iia Scientific Award. Gustavo was recently invited to Lodz Institute of Technology in Poland in order to advance his research. 

 

In 2015 the International Irradiation Association is supporting the Tihany Symposium on Radiation Chemistry and in 2016 iia will continue the recent tradition of supporting the next IRaP meeting. These meetings will provide a valuable insight into developments and research in the field of radiation chemistry. While the initial focus of the newsletter will probably be radiation chemistry we will be keen to expand this to include research that is taking place in other areas of radiation science. Our aim will be to produce a scientific newsletter every four months. 

 

This newsletter provides a number of links "read article". Destination websites may/will require access codes and/or will require readers to pay for access to the article.

 

We would encourage readers to submit comments and details of research that would be of interest to the irradiation community using the link.

A manuscript entitled "Temperature- and pH-sensitive IPNs grafted onto polyurethane by gamma radiation for antimicrobial drug-eluting insertable devices"  has been recently published on the Journal of Applied Polymer Science. The article details the development of advanced implantable biomedical devices using irradiation techniques.

"Temperature- and pH-sensitive interpenetrating polymer networks (IPNs) and semi-interpenetrating polymer networks (s-IPNs) were γ-ray grafted onto polyurethane (Tecoflex®; TFX) to obtain vancomycin-eluting implantable medical devices with minimized risk of infections. N-isopropylacrylamide (NIPAAm) was grafted onto TFX catheters and films via a preirradiation oxidative method or via a direct method. The PNIPAAm network facilitated acrylic acid inclusion and subsequent polymerization/crosslinking, under specific reaction conditions. IPNs and s-IPNs systems were characterized regarding the amount of grafted polymers, surface properties (FTIR-ATR, ESEM, EDX), thermal behavior (DSC), and their temperature- and pH-responsiveness. Loading and release of vancomycin for preventing in vitro growth of Staphylococcus aureus were also evaluated. Antimicrobial activity tests and hemo- (hemolysis, protein adsorption, thrombogenicity) and cyto-compatibility (cell viability and production of cytokines and NO) assays indicated that the modification of TFX by γ-radiation may improve the performance of polyurethanes for biomedical applications."  Read Article.

Review on Nanogels
Slawomir Kadlubowski
Institute of Applied Radiation Chemistry, Lodz University of Technology, Lodz, Poland.

A manuscript entitled "Radiation-induced synthesis of nanogels based on poly(N-vinyl-2-pyrrolidone)-A review"  has been recently published on the Rad. Phys. Chem. Journal. The article details the synthesis of polymer nanogels using irradiation techniques on an up-to-date approach.

"Nanogels are nanometer-scale two-component systems consisting of a permanent three-dimensional network of linked polymer chains, and molecules of a solvent filling the pores of this network. A number of synthetic routes have been developed for nanogels. One of them is based on intramolecular cross-linking of individual polymer chains and ionizing radiation is a suitable tool for initiation of this process. Poly(N-vinyl-2-pyrrolidone)-PVP-was one of the first polymers used to obtain intramolecularly cross-linked macromolecules using this method called preparative pulse radiolysis. This review summarizes radiation-based techniques used for synthesis of PVP-derived nanogels starting from preparative pulse radiolysis, through irradiation of thermally collapsed PVP and cross-linking in microemulsion up to formation of PVP based interpolymer complexes. In addition, possible practical applications of PVP-based nanogels have been presented mainly in the biomedical field" Read Article.

A manuscript entitled "Influence of radiation processing of grapes on wine quality"  has been recently published on the Rad. Phys. Chem. Journal. The article reports the use of irradiation synthesis and is of particular interest by Food irradiation scientists.

"Grapes (Var. Shiraz and Cabernet) were subjected to radiation processing (up to 2 kGy) and wines were prepared and matured (4 months, 15 °C). The wines were analyzed for chromatic characteristics, total anthocyanin (TA), phenolic (TP) and total antioxidant (TAC) content. Aroma of wines was analyzed by GC/MS and sensory analysis was carried out using descriptive analysis. TA, TP and TAC were 77, 31 and 37 percent higher for irradiated (1500 Gy) Cabernet wines, while irradiated Shiraz wines demonstrated 47, 18 and 19 percent higher TA, TP and TAC, respectively. HPLC-DAD analysis revealed that radiation processing of grapes resulted in increased extraction of phenolic constituents in wine with no qualitative changes. No major radiation induced changes were observed in aroma constituents of wine. Sensory analysis revealed that 1500 Gy irradiated samples had higher fruity and berry notes. Thus, radiation processing of grapes resulted in wines with improved organoleptic and antioxidant properties." Read Article.

Development of New Applications of Machine Generated Food Irradiation Technologies 

(Reference number: D62024)

Most of the food irradiated in the world is treated with gamma rays generated by the radionuclide cobalt-60, but using electrically generated "machine source" radiation could broaden the choice of food irradiation technologies. This is strategic research and the aim of the CRP is to accelerate research and development to facilitate implementation of practical techniques using electron beam (EB) and X ray to unlock the potential of machine sources for radiation treatment of agricultural and food products. The project will adopt an international and multidisciplinary approach involving cooperative research and development between food scientists, electrical engineers, equipment manufacturers, and stakeholders within the agro-food industry.

A meeting of experts in 2014 identified the following topics, and these and other proposals meeting the CRP aims and objectives can be selected for inclusion:

  • New concepts of EB and X ray machines that could easily be integrated in existing food processing lines of development of novel pre-packaged food irradiated by EB or X ray. Effects on foodborne microorganisms of EB and X rays at energies below 300 keV or at energies between 5 and 7.5 MeV for X rays. Potential creation of short-lived radionuclides of toxicological significance with X rays having energies between 5 and 7.5 MeV. Dosimetry methods and tools usable for EB and X rays with energies ranging from 5 to 7.5 MeV and for EB and X rays having an energy below 300 keV.
  •  
  • Proposals can be made using the form that can be downloaded from this page of the IAEA website: http://cra.iaea.org/cra/forms.html.

The first Research Coordination Meeting (RCM) will be held in Vienna, Austria from 19 to 23 November 2015.
