Members of the Department for Nanostructured Materials Monika Kušter, dr. Zoran Samardžija, dr. Matej Komelj, dr. Sorour Semsari Parapari, dr. Matejka Podlogar, prof. dr. Jean-Marie Dubois and prof. dr. Sašo Šturm and an associate of the Department of Surface Engineering prof. dr. Janez Kovač published in a journal Crystals a study entitled: “Impact Of Tuned Oxidation on the Surface Energy of Sintered Samples Produced from Atomised B-Doped Al-Cu-Fe Quasicrystalline Powders”. In the article, we investigated the dynamics of the surface-energy changes on a boron-doped quasicrystalline AlCuFe material. The results of the study contribute to a broader insight into a quasicrystalline-material surface-energy controlled change under atmospheric conditions, as a result of the controlled oxide-layer growth. The results indicate the possibility of further optimization, i.e. engineering of quasicrystalline surfaces, which enables their applicative use in various composite systems strengthened by a quasicrystalline phase. The editors chose the article and graphical abstract for…
The Jean-Marie Dubois Prize will be awarded this year to Prof Dr. Michael Baake, a German mathematician and theoretical physicist working at the University of Bielefeld. The prize is named after our colleague from K7 and is administered by the State University of Iowa, USA, to “recognize important, sustained research on any aspect of quasicrystals within the 10 years preceding the award”. More details can be found at: https://www.icq15.sites.tau.ac.il/awards. The prize was established at Iowa State University by our late colleague, Professor Patricia A. Thiel, who pioneered research on the surface physics and chemistry of quasicrystals in close collaboration with JM Dubois. Together, they led an international laboratory between Ames Laboratories and the CNRS to promote the development of the applied physics of these new materials. Today, a similar binational initiative is active between the JSI and the CNRS, focusing on complex alloys, in line with a long-standing collaboration on…
Zdravljenje je vedno najbolj učinkovito, če se lahko bolezni lotimo kar najbolj neposredno, pri samem viru težav. A do vira pogosto sploh ni lahko priti. Denimo, če govorimo o okvarjenem genu, ki bi ga morda želeli utišati, da ne bi več povzročal težav. Področje tovrstnih genskih terapij daje v zadnjem času že zelo spodbudne rezultate in vanj so seveda usmerjeni številni raziskovalni napori. Prav tako zahtevno se je, po drugi strani, prebiti do bolj odmaknjenih tumorjev, ki se tako zlahka izmaknejo terapiji, za katero pa vemo, da ima celo paleto škodljivih stranskih učinkov. Naj gre torej za takšno ali drugačno zdravljenje, ključno vprašanje vsekakor je, kako spraviti pravo učinkovino na pravo mesto. Da bi bil ta transport učinkovin še povsem biorazgradljiv, dr. Nina Kostevšek z odseka za nanostrukturne materiale Instituta “Jožef Stefan” raziskuje možnosti uporabe membran rdečih krvnih celic. https://365.rtvslo.si/arhiv/podobe-znanja/174962029
Prostorsko-svetlobno instalacijo sestavlja niz kinetičnih objektov, ki so nastali na podlagi fizikalnih vizualizacij magnetnih skirmionov, toplotnih kvazidelcev v obliki vrtincev v strukturi magnetnih materialov, ki lahko prenašajo informacije in imajo specifični tehnični potencial v razvoju napredne svetlobne in ekološko odgovorne tehnologije. Kinetični objekti variirajo v obliki, saj ne poskušajo objektivno razlagati in posnemati znanstvenih vizualizacij, ampak interpretirajo različne tipe modelizacij (strukture, diagrame, sheme, tridimenzionalne ponazoritve gibanja delcev ali magnetnih silnic). Formalni rezultat te umetniške interpretacije je prej fantazmagoričen kot verističen in ta vidik je poudarjen z dodatnimi učinki kinetičnega vrtenja, svetlobnimi in video projekcijami, ki skupaj ustvarjajo fiktivno prostorsko krajino v gibanju. Kinetična svetlobno-prostorska instalacija deluje kot zaznavni (optični in telesni) eksperiment in z izzivanjem ustaljenih percepcijskih navad širi kognitivno izkušnjo gledalca. Projekt stremi k prepletanju estetske izkušnje s širšimi vprašanji o materialnem ustroju našega vesolja na subatomski ravni, sprašuje o subjektivnih načinih razumevanja in doživljanja narave fizikalne stvarnosti na eni strani…
Ljubljana, 22. maja – Saša Novak je znanstvenica s področja naprednih materialov in komunikatorica znanosti. Že desetletje si prizadeva znanost približati medijem in javnosti v okviru projekta Znanost na cesti, ki danes praznuje deseto obletnico. Za STA je spregovorila o začetkih projekta, preteklih in trenutnih izzivih in o stanju komuniciranja znanosti v Sloveniji. Saša Novak je pred natanko desetimi leti skupaj s sodelavko na Institutu Jožef Stefan (IJS) Kristino Žagar Soderžnik ustanovila projekt Znanost na cesti, s katerim so znanost ponesli med ljudi. Na današnji dan pred desetimi leti je namreč potekalo prvo predavanje v okviru projekta, ki ga je izvedel Luka Snoj z Instituta Jožef Stefan. V okviru projekta so doslej pripravili že preko 220 poljudnoznanstvenih predavanj, okroglih miz in znanstvenih slamov, pa tudi podcastov, blogov in natečajev. Za svoje delo na področju komuniciranja znanosti je Saša Novak letos prejela tudi prestižni naziv komunikatorica znanosti 2022.

JSI meeting on catalysts synthesis, characterization and applications – 25.05.2023 The scope is to organize a workshop where we would like to connect knowledge from various research areas at JSI with the goal of combining efforts in related/complementary fields. Talks are invited and will cover: – different methods for catalysts synthesis such as, but not limited, wet chemistry, anodic oxidation, electro deposition, magnetron sputtering, etc. – characterization techniques to evaluate morphology, composition, crystal structure, including various physicochemical properties as, but not limited, UV-VIS, XPS, SEM, TEM, XRD, Raman, EPR, etc. – catalyst in the working environment as performance measurements or modeling under different catalytic conditions for applications in various fields including, but not limited, to organic pollutant and microplastic removal, water splitting, CO2 reduction, etc. The aim of this workshop is to synchronize activities towards large European or/and national research project. Organizers: Belisa Alcantara Marinho, Matejka Podlogar, Sašo Šturm –…
