Competition: Best Microscopy Image Award (SDM2024)

At the 5th Slovene Microscopy Symposium (SDM24), which took place on May 16 and 17, 2024 in Rogla, a competition was held for the best microscopic image. The cover features an award-winning image in the field of materials science. It is a complex microstructural study of welds of two high-strength Al alloys (Al-Cu-Mg and Al-Cu-Mg-Zr). The picture shows a detail of a crystal structural alloy with parallel defects, aquired in the HAADF technique on the new “state of the art” scanning transmission electron microscope Spectra 300. TEM preparation of the sample and analysis is the author’s work of Sandra Drev.

5th Slovenian Microscopy Symposium, -May 16th and 17th 2024- ROGLA

The main purpose of the conference is to encourage collaboration between younger and well-established Slovenian researchers and other users of microscopic techniques working in the fields of life science, material science, and industry. In addition to presenting the latest achievements in microscopy, the conference is also intended to showcase the activities of various groups using microscopic techniques at all levels of resolution.

The registration fee is 100 EUR for members of the Slovenian Society for Microscopy and 150 EUR for non-members, including participation in the symposium, abstract book, coffee breaks, and lunch on Friday. We have negotiated a special rate for accommodation with Hotel Superior on Rogla, including full board. When making a hotel reservation (reservation email:, please mention that you will be attending the SDM 2024 meeting.

Mnemonic Rutile–Rutile Interfaces Triggering Spontaneous Dissociation of Water (DOI: 10.1002/adma.202470027)

Collaborations with the Center for Electron Microscopy and Microanalysis, Department of Surface Engineering and Chemical Institute.

In the article Mnemonic Rutile-Rutile Interfaces Triggering Spontaneous Dissociation of Water (doi: 10.1002/adma.202308027), Vesna Ribić, Vanja Jordan, Aleksander Rečnik, Sandra Drev, Janez Kovač and Goran Dražić demonstrate that epitaxial rutile fibers grown in acidic conditions are capable of conveying their structurally encoded properties into a neutral medium when re-immersed. Their very specific translation state triggers spontaneous cracking of the O─H bond resulting in water dissociation.

Water interaction with mineral surfaces is a complex living system decisive for any photocatalytic process. Resolving the atomistic structure of mineral–water interfaces is thus crucial for understanding these processes. Fibrous rutile TiO2, grown hydrothermally on twinned rutile seeds under acidic conditions, is studied in terms of interface translation, atomic structure, and surface chemistry in the presence of water, by means of advanced microscopy and spectroscopy methods combined with structure modeling and density functional theory calculations. It is shown that fibers while staying in stable separation during their growth, adopt a special crystallographic registry that is controlled by repulsion forces between fully hydroxylated and protonated (110) surfaces. During relaxation, a turbulent proton transfer and cracking of O─H bonds is observed, generating a strong acidic character via proton jump from bridge ─OHb to terminal ─OHt groups, and spontaneous dissociation of interfacial water via a transient protonation of the ─OHt groups. It is shown, that this specific interface structure can be implemented to induce acidic response in an initially neutral medium when re-immersed. This is thought to be the first demonstration of quantum-confined mineral–water interface, capable of memorizing its past and conveying its structurally encoded properties into a new environment.

Happy New Year

A great leap forward for all.

Comming soon_TEM field modernization

A little more and the Center for Electron Microscopy and Microanalysis will get new equipment in the field of transmission electron microscopy.
View into the Future.
