Associate professor at University of Novi Sad, Serbia. Uses X-ray diffraction on crystals to open windows into the world of atoms.

Joined May 2020
Our crystallographic and computational study shows how cis/trans isomerism reshapes supramolecular architecture. Energy vector analysis reveals the interplay between resonance-assisted hydrogen bonds and dispersion-driven stacking. Now in @CrystEngComm #crystallography Link 👇

Software optimized to fit ruby fluorescence spectra, automatically extract the peak positions and calculate the pressure according to the Ruby2020 gauge is presented.
If you're measuring ruby fluorescence to determine the pressure in your #DAC experiments, try our new program: "CrimsonCalc: a software tool for pressure determination based on ruby fluorescence spectra". Just published in @JApplCryst. @VirantMiha @IUCr

An example of the reverse thermosalient effect i.e. the cryosalient effect. #crystallography
Cooling of this sample induces a phase transition that causes the crystal to disintegrate or maybe even leap off the mount. It happens around 150 K, while the crystal remains stable above that. I mounted multiple crystals and observed the same behavior each time!

While working on these structures, I encountered disorder, non-merohedral and pseudo-merohedral twins, cases where the unit cell’s metric symmetry exceeds that of the crystal, and other crystallographic complications. It has been a fascinating and rewarding experience! #research

Most of these structures were collected at room temperature on a Gemini S diffractometer (@RigakuOxfordXRD) assembled in 2007. The dataset comprises mainly coordination compounds with organic ligands, as well as various organic molecules, including natural product derivatives.

Milestone: my 200th deposited crystal structure is now in the CCDC @ccdc_cambridge (first one in 2012 CCDC 870175, latest today CCDC 2483173). Over the past 13 years, the database has almost tripled in size — adding 1.6 million entries!🧵👇 #crystallography #CSD #Xray #chemistry

I was trained that waiting for the first frame to appear on the screen at the X-ray diffractometer was a must -- sometimes up to 10 minutes if exposure times were long. Now it's surreal that modern diffractometers can collect the entire dataset in that time. #Crystallography

Outstanding paper (and cover page) by @MaticLozinsek, congrats! 👏
Our new @InorgChem cover features Prof. Neil Bartlett’s famous synthesis of XePtF₆ by oxidation of Xe with PtF₆, the #3DED #CrystalStructure of XeF₂·2PtF₄, and the DFT-optimized structural models of XePtF₆. #MyACSCover @ACSPublications #ChemTwitter 👉 https://t.co/T4ir4LBuvs

We used 3D electron diffraction to elucidate the crystal structures of XePt₂F₁₀ and XePd₂F₁₀. Based on these findings, we propose structural models for the first noble-gas compound, XePtF₆. @InorgChem @ACSPublications #3DED #ChemTwitter #OpenAccess

Journal Citation Reports are now updated in our national service. I checked the top journals in my field and also looked at those with suppressed #ImpactFactor. Seeing Wiley's Applied Organometallic Chemistry on that list really surprised me. #JCR2025 @wileyinresearch #chemistry

Researchers from @TempelaarTeam and @UWMadisonChem found that a centrosymmetric #crystal—once thought incapable of #chirality—can act chiral. This unexpected behavior could lead to new light-controlling tech, from sensors to optical displays. https://t.co/n7ht2U503e
