Gregor Filipič, Luka Pirker, Anja Pogačnik Krajnc, and Maja Remškar from the Department of Condensed Matter Physics F5 and Marjan Ješelnik from smartMELAMINE from Kočevje published a paper in the journal Materials with the title Enhanced Filtration Efficiency of Natural Materials with the Addition of Electrospun Poly(vinylidene fluoride-co-hexafluoropropylene) Fibres. In the article the researchers have increased the filtration efficiency of natural materials by depositing a thin layer of electrospun PVDF fibres. By optimising the layer thickness of the electrospun fibres the filtration efficiency can be tuned and thus significantly reduce the amount of plastic waste.

Luka Pirker from the Department of Condensed Matter Physics F5 together with colleagues from Jaroslav Heyrovský Institute for physical chemistry from Prague published a paper in the journal 2D Materials with the title Sulphur isotope engineering of exciton and lattice dynamics in MoS2 monolayers.

In the published paper, the researchers synthesized MoS2 with different isotopes of sulphur, revealing the influence of phonons on the optoelectronic properties of MoS2. By varying the isotopic composition, the optoelectronic properties of the material can be adjusted for various applications, and at the same time provides a unique platform for understanding the fundamentals of optical processes in 2D systems.

Luka Pirker and Maja Remškar from the Department of Condensed Matter Physics F5 and colleagues from the University of Regensburg (Germany) published a paper in the journal Advanced Materials with the title Non-Destructive Low-Temperature Contacts to MoS2 Nanoribbon and Nanotube Quantum Dots.

Molybdenum disulphide (MoS2) has inspired scientists for more than a decade with its extraordinary properties. Among others, it also has unique electrical properties, which makes it interesting for a wide range of electronic applications, from

transistors and sensors to quantum computers.

In the published article, the researchers presented a new way of making electrical contacts using bismuth on MoS2 nanotubes and nanoribbons, which were synthesized at IJS. Good electrical contacts are an important step towards quantum technologies, as most measurements take place at extremely low temperatures (T < 100 mK). The new discovery will enable researchers to discover new material properties in the quantum regime in MoS2.

George Cordoyiannis, PhD from the Department of Condensed Matter Physics F5 and colleagues from Belgium and Denmark have published inPhysica Status Solidi A the review article QCM-D Study of the Formation of Solid-Supported Artificial Lipid Membranes: State-of-the-Art, Recent Advances, and Perspectives.

An overview of the lipid vesicle adsorption and rupture under different experimental conditions is given. The current understanding of the mechanisms relies on surface sensitive techniques, such as quartz crystal microbalance with dissipation monitoring and atomic force microscopy. We provide various examples how the vesicle adsorption and rupture are influenced by varying the lipid size and charge, the type of buffer and the adhesion strength of solid substrate.

In recent years, transitional metal dichalcogenides (TMDCs) have opened a new frontier in the area of field emission devices. Due to their layered structure and the presence of thin and sharp edges with high aspect ratios the local electric field is enhanced which plays an important role in filed emission.

L. Pirker, M. Remškar in B: Višić from the Department of Condensed Matter Physics F5 together with colleagues from OTH Regensburg (Germany) published an article in Advanced Functional Materials titled MoxWx–1S2 Nanotubes for Advanced Field Emission Application, where they report on the synthesis and characterization on mixed MoWS2 nanotubes. Single nanotube field emission devices were prepared and show promising results comparable with other TMDC devices.
