V diplomskem seminarju obravnavamo dogajanje ob temperaturno induciranem faznem prehodu tekočega kristala med ne matično in izotropno fazo. V ta namen smo sintetizirali tekoči kristal MBBA in z invertnim polarizacijskim mikroskopom opazovali dogajanje ob faznem prehodu. Vzorec smo izpostavili hitri ...

Superprevodne kovine lahko delimo na dva tipa, ki jih karakteriziramo s tipičnimi razdaljami sistema. V analogiji lahko tudi za smektične tekoče kristale uvedemo podobno delitev. Smektike tipa I in tipa II ločimo s t. i. Ginzburgovim parametrom. V magistrski nalogi bomo preučevali odziv obeh tipov s ...

The key reason behind the richness of different structures and patterns displayed in nature is the universal mechanism of symmetry breaking. It shapes configurations at all length scales encountered in universe. Structures reached via symmetry breaking transitions are commonly described in terms of ...

We demonstrate the fabrication of good quality surface alignment layers on glass by Direct Laser Writing method using a 2-photon polymerisation technique. We use commercially available photosensitive resins to print alignment layers by scanning the focal point of a femtosecond laser near the resin-g ...

Fractals are remarkable examples of self-similarity where a structure or dynamic pattern is repeated over multiple spatial or time scales. However, little is known about how fractal stimuli such as fractal surfaces interact with their local environment if it exhibits order. Here we show geometry-ind ...

Aerosol absorption coefficient measurements classically feature a very large uncertainty, especially given the absence of a reference method. The most used approach using filter-photometers is by measuring the attenuation of light through a filter where aerosols are being deposited. This presents se ...

The JATAC campaign in September 2021 and September 2022 on and above Cape Verde Islands resulted in a large in-situ and remote measurement dataset. Its main objective was the calibration and validation of the ESA satellite Aeolus ALADIN Lidar. The campaign also featured secondary scientific objectiv ...

There exists a lack of aerosol absorption measurement techniques with low uncertainties and without artefacts. We have developed the two-wavelength Photothermal Aerosol Absorption Monitor (PTAAM-2λ), which measures the aerosol absorption coefficient at 532 and 1064 nm. Here we describe its design, c ...
