Rigid mesh of DNA polyelectrolytes
Our colleagues, K. Salamon, D. Aumiler and T. Vuletić along with G. Pabst from University of Graz have published an article in Macromolecules, a top journal in polymer science. Utilizing different experimental techniques and studying both the structure and the dynamics they have demonstrated the existence of a rigid mesh formed by the polyelectrolytes deoxyribonucleic acid (DNA) and hyaluronic acid (HA).

Graphene stairways to Carbon
New fronts in epitaxial graphene research regard tailoring the growth of graphene on stepped surfaces in order to make use of periodic modulations to the electronic structure of graphene. The work of our colleagues, in particular of the leading author Iva Šrut, on the growth of graphene on stepped Ir(332) presents a significant contribution to this new topic and is just accepted for publication in Carbon.

Thermal transport in doped Mott-insulator
Our colleague Veljko Zlatić, Emeritus Scientists at Institute of Physics, has just published, in collaboration with J.K. Freericks, an article in Physical Review Letters. By analytic theoretical treatment of doped Mott insulator the authors show that, depending on temperature and physical parameters, figure-of-merit (ZT) of such a system can be enhanced to reach values of the order of 100, a distinct aim in search for new and efficient thermoelectrics.

Patent application of Institute of Physics published
Institute’s international (PCT) patent application, comprising an affirmative international searching authority report, has recently been published by PCT/WIPO. Patent applies to the new construction of the cryostat intended for various demending experimental research in the liquid helium range, consuming however no liquid helium as a cooling medium. Authors of the patent application are Mladen Prester and Đuro Drobac.

SeCuO3: Three-dimensional network of Cu2+ -tetramers
Examples of quantum effects determining behaviour of macroscopic objects are not very common- levitation of permanent magnet over the cooled high-temperature superconductors represents one of them. In the article published recently in Physical Review B Ivica Živković and numerous coauthors from IF and other research institutions show that magnetic system SeCuO3 belongs to the latter category.

Transient dynamics of hot electrons on surfaces
Dynamics of hot electrons at surfaces irradiated by short femtosecond laser pulses deviates strongly from standard quasiparticle description. To what extent the standard description is still applicable is subject of the most recent review article of our colleague Branko Gumhalter, published in Progress in Surface Science.

Fine details in magnetic ordering of magnetoelectric Cu2OSeO3
Armed by high-quality single crystals manufactured by Helmut Berger (EPFL) our colleagues I. Živković and T. Ivek, in collaboration with D. Pajić (PMF-Zagreb ), have managed to clarify unresolved issues in magnetic ordering of Cu2OSeO3, a system previously claimed to be magnetoelectric. The results are recently published in Physical Review B.

Electron-phonon coupling in doped graphene
The electron-phonon coupling in highly doped graphene that is, for instance, a part of intercalated graphite compounds (KC8, CaC6), has been widely studied. The results have been, however, rather confusing up to now. The determined coupling strengths λ are drastically different, claimed to be in the interval from the negligible value 0.04 to the very high one, 4.
A contribution to the ongoing debate has now been published by our colleagues I. Pletikosić, M. Kralj, M. Milun and P. Pervan in Physical Review B.

Charge Kondo anomaly in the semiconductor PbTe
Our colleague Veljko Zlatić, Emeritus Scientist of Institute of Physics, has recently published, in collaboration with T.A.Costi, Forschunsgzentrum Jűlich, article in Physical Review Letters establishing an unusual dependence of the properties of the semiconductor PbTe on Tl-doping in Kondo anomaly. One does not deal however with classical scenario of Kondo scattering on magnetic impurity but with a Kondo-like effect involving charge degrees of freedom only!

Electrostatic energy of viruses
As announced by Jožef Štefan Institute our colleague Antonio Šiber and his collaborators from Jožef Štefan Institute, A. Lošdorfer Božič and R. Podgornik, published a review article on physical modeling of viruses in Physical Chemistry Chemical Physics. The article is singled out as 'Cover Article' and illustrated on journal’s front page by authors' model of a virus.
