The associates of the »Jožef Stefan« Institute, Melita Sluban (F5), Polona Umek (F5) and Jernej Iskra (K3), in collaboration with the researchers from the University of Ljubljana (Faculty of chemistry and chemical technology) and the University of Bucharest, for the first time successfully catalysed the aldol condensation, which is the most common reaction for creation of new carbon-carbon bonds, using protonated titanate nanotubes. Such a reaction is a ‘green’ alternative to the current industry practice of using stoichiometric amounts of homogeneous catalyst, which cannot be recycled after the reaction ends. In contrast, when using protonated titanate nanotubes, a mere catalytic amount of material ensures a successful reaction, the catalyst can be used several times and it was even successful in a large-scale experiment. The work was published in the article Protonated titanate nanotubes as solid acid catalyst for aldol condensation in the Journal of Catalysis, one of the lead journals in the field of catalysis.

On January 24, 2017,  Nature Communications published a paper called Fractal Nematic Colloids written by Uroš Jagodič, Igor Muševič and Miha Ravnik, associates of the Department for Condensed Matter Physics (F5) at the “Jožef Stefan” Institute and of the Faculty of Mathematics and Physics at the University of Ljubljana in collaboration with the associates of the Sharif University of Technology in Iran. They used two-photon laser lithography to create colloidal particles in the shape of fractal Koch stars, which they studied in liquid crystal. The fractal particles influence the ordering of the liquid crystal and create topological defects, whose number increases exponentially in accordance with the fractal order of particles. This is the first time that fractal states were created in soft matter.

The Physical Review Letters published a paper called Low-Temperature Global Symmetry Reduction in the Kagome Antiferromagnet Herbertsmithite by Andrej Zorko and Matjaž Gomilšek, associates of the Department for condensed matter physics at the “Jožef Stefan” Institute. In collaboration with groups from Croatia, USA and France, they were the first to observe symmetry brake in a Herbertsmithite crystal, which is known as the paradigm of a quantum antriferromagnet on a Kagome spin lattice, where the theory predicts a magnetic disordered ground state of spin liquid. Such break could hold the key information on the essential nature of the magnetic ground state of this crystal. After more than a decade of intensive research, this discovery offers a completely new insight into the enigmatic ground state of a spin liquid on a Kagome spin lattice.

The journal Proceedings of the National Academy of Sciences of the United States of America published a paper entitled Working stroke of the kinesin-14, ncd, comprises two substeps of different direction, written by Andrej Vilfan, associate of the F5 Department, in collaboration with two groups from Dresden and Warsaw. Molecular motors such as myosin, kinesin and dynein transform chemical energy into mechanical work performed through longitudinal movement along the citosceletal fillaments. In many cases, the torque also causes the fillaments to swivel. The article talks about the measurments performed on the kinesin-14, a motor involved in the cell division. By observing the translation and rotation in different chemical circumstances, we can use theoretical modeling to reconstruct the work cycle of the motor. The results show how measurements on a larger ensemble allow us to determine the characteristics of an individual molecules.
