Highlights of the 8th International Dendrimer Symposium

The 8th International Dendrimer Symposium was successfully held in Madrid on June 23–27 with Prof. Maria Angeles Muñoz-Fernandez as the chair. More than 200 scientists from all over the world participated in IDS-8 to present their latest achievements in dendrimer science.

The meeting opened with the “Ramon Areces” welcome lecture delivered by Prof. Virgil Percec, who depicted a fascinating material genome approach to construct complex dendrimer systems. Using dendritic motifs to create different types of fractal patterns was nicely exemplified by Prof. George Newkome, whereas capitalization on new strategies for dendrimer synthesis was the main focus in the lecture of Prof. René Roy. Prof. Dieter Schlüter reported the synthesis and characterization as well as discontinuities in dendronized polymers, whereas Dr. Anil Patri presented lessons learned from preclinical assessment of dendrimers.

Prof. Donald Tomalia gave a vivid and brief overview on the development of dendrimer science and focused in particular on the dendritic effects, which were further discussed in the lectures of Dr. Anne-Marie Caminade and Dr. Takuzo Aida. The meeting ended with the closing lecture of Dr. Jean-Pierre Majoral, who discussed the dendrimer space in nanomedicine and foresaw a bright future for dendrimers in therapeutic applications.

Poster prizes provided by several sponsors, including NJC, were awarded just before this closing lecture. The NJC laureats were profiled in an earlier post.

It is to note that, beside the excellent scientific program, there was a fantastic social program with a visit of the Prado museum and the Real Madrid stadium as well as the flamenco gala evening.

The next IDS meeting will be hosted by René Roy in Montreal, Canada in 2015. NJC will be there and we look forward to another excellent conference in the fascinating field of dendrimers.

Meet Our Authors – August Issue 2013

Two authors of NJC’s August issue are interviewed for this month’s Meet our Authors feature.

Our first author is Dr. Faina Gelman, who is researcher at the Institute of Geological Survey of Israel, The Hebrew University of Jerusalem. Her current research interests are environmental chemistry and stable isotope analysis. She particularly focuses on development of new analytical tools for stable isotope analysis and their applications for understanding chemical and biochemical transformations of organic compounds.

In their NJC paper, Faina with her colleagues demonstrated determination of bromine kinetic isotope effect on Grignard reagent formation –one of the fundamental reactions of brominated organics. ” Since our work combines novel analytical, theoretical and organic chemistry approaches, we wanted to submit it to a more general-focused journal, such as NJC is, from our point of view” commented on choosing NJC.

And what contemporary scientific issue is she most concerned about: “I am very much concerned about environmental pollution and would like to find an efficient way to treat this problem “she replied. Besides her research activity, Faina likes to spend time with her family.

Bromine kinetic isotope effects: insight into Grignard reagent formation by Lukasz Szatkowski, Agnieszka Dybala-Defratyka, Charlie Batarseh, Jochanan Blum, Ludwik Halicz and Faina Gelman ; New J. Chem., 2013, 37, 2241-2244; DOI: 10.1039/C3NJ00197K.

The second author is Jürg Hulliger, who is a Professor of chemistry at the University of Berne, Switzerland. His research interest centers on Crystal growth, properties and solid state theory. His contribution to this month’s issue is Focus article that reviews on polar properties of solid molecular matter.”Here we review basic theoretical views on growth induced polarity in molecular crystals giving also all known experimental examples we have by today, which domonstrate polarity Formation. ”

If Jürg could solve any scientific problem, it would be: “Constructing equipment being able to say : a small Crystal of the size of a few 100 nm is (i) superconductive, (ii) is composed of these elements and (iii) shows this crystal structure. Such an Equipment may be used to analyze your combinatorial ceramic samples.”

In the non-lab world, Jürg is fascinated by interior decoration in the style of the 18th century, renovation of antics and art.

A stochastic principle behind polar properties of condensed molecular matter by Jürg Hulliger, Thomas Wüst, Khadidja Brahimi, Matthias Burgener and Hanane Aboulfadl  New J. Chem., 2013, 37, 2229-2235 DOI: 10.1039/C3NJ40935J

We thanks to Faina and Jürg for accepting our invitation to talk about themselves and their work!

Your Vacation Reading from NJC

The August issue of New Journal of Chemistry contains 50 articles for your summer reading enjoyment.

Bi-polar states of solid matter.

Among the highlights of this issue, don’t miss the latest Focus review, by the group of Jürg Hulliger at the University of Bern in Switzerland. Using condensed matter theory, the key message that molecular solids can end up in bi-polar states has implications for tissue formation, function and repair. This is an interesting example of how findings in one field might lead to breakthroughs in a very different field.

A stochastic principle behind polar properties of condensed molecular matter by Jürg Hulliger, Thomas Wüst, Khadidja Brahimi, Matthias Burgener and Hanane Aboulfadl, New J. Chem., 2013, 37, 2229-2235. DOI: 10.1039/C3NJ40935J

Cover for the work of Mikata et al.

The outside and inside front covers feature highly ranked works. This month the striking outside front cover was proposed by the group of Yuji Mikata from Nara Women’s University in Japan. They achieved OFF-ON, ratiometric or ON-OFF responses towards mercury and iron cations by modifying the substitution pattern on their basic molecular skeleton.

Thioether-tethered bisquinoline derivatives as fluorescent probes for mercury(II) and iron(III) ions by Yuji Mikata, Fumie Nakagaki and Kaori Nakanishi, New J. Chem., 2013, 37, 2236-2240. DOI: 10.1039/C3NJ00233K

Cover for the work of Andruh and collaborators.

A collaborative effort by several groups in Romania and France is featured on the inside front cover. They determined the crystal structures and studied the magnetic and photophysical properties of sixteen 3d–4f Schiff-base complexes. The interaction between the two metal ions lead to interesting effects on the properties.

A new synthetic route towards binuclear 3d–4f complexes, using non-compartmental ligands derived from o-vanillin. Syntheses, crystal structures, magnetic and luminescent properties by Masood Sarwar, Augustin M. Madalan, Carmen Tiseanu, Ghenadie Novitchi, Catalin Maxim, Gabriela Marinescu, Dominique Luneau and Marius Andruh, New J. Chem., 2013, 37, 2280-2292. DOI: 10.1039/C3NJ00199G

NJC poster prize at 5th ECCLS

We are delighted to present the recent poster prizes awarded at the 5th European Conference on “Chemistry for Life Sciences” (5th ECCLS) in Barcelona, that gathers an ensemble of scientists at the crossroads between chemistry, biology, biophysics and material science.

Two young scientists Montserrat Serra-Batiste and Sven Hofmann received NJC Poster Prizes that reward creative and multidisciplinary research works in the chemical sciences.

Montserrat Serra-Batiste is a postdoctoral researcher in the group of the Prof. Ernest Giralt at the Institute for Research in Biomedicine, Barcelona (Spain) working under the supervision of Dr. Natàlia Carulla since September 2010.

Montserrat’s winning poster dealt with well-defined Aß42 oligomers in a biomimetic membrane environment. The idea project started with the idea of Dr Natàlia Carulla of stabilizing Aß oligomers by using an environment similar to what this peptide have in vivo. Different conditions have been testing by different techniques in order to get a stable and homogeneous preparation of Aß oligomers. As a result, an Aß42 hexamer (named (Aß42)6Membrane) has been stabilized which adopts extensive ß-sheet secondary structure and exhibits specific Aß42-Aß42 interactions. Preparation of (Aß42)6Membrane should open the possibility to explore more in deep the role of Aß oligomers in Alzheimer’s disease.

Her future plans include working with Natàlia to characterize the structure and the biological relevance of this Aß42 hexamer and contribute in solving the puzzle of Alzheimer’s disease. Besides research activities Montserrat loves cooking and dancing.

The award-winning poster of Sven Hofmann was entitledCarbaboranes in Short Neuropeptide Y Analogs – Redirecting BiologicalActivity”. Carbaboranes are icosahedral boron-carbon clusters mimicking phenyl rings. In particular, they present a three-dimensional hydrophobic structure and are capable of providing a special type of hydrogen bonding, the so-called proton-hydride bonding. Their unique chemical properties are perfectly suited for improving the biological activity of small bioactive molecules but also of peptide analogs.

Sven is a graduate student working in the research group of Prof. Annette G. Beck-Sickinger at the University of Leipzig, Leipzig (Germany) since October 2010. Working in the field of chemical modification of peptides to gain receptor subtype selectivity and biological stability, he especially focuses on the synthesis of short functionalized peptide ligands as selective diagnostic and therapeutic tools.

His future plans are not fixed yet. However, he will finish his Ph.D. in 2014 and he will apply for a postdoctoral research position abroad. Outside of the lab, Sven’s favorite activities are running, cycling, athletic sport challenges and travelling.

The two laureates received a one-year subscription to the journal and a RSC book. Our thanks go to the organizers of the conference for their help in organizing these awards, and our deep gratitude to all of the senior scientists who served on the jury to select the two following winners:

NJC wishes them continuing success in their research!
