Pulsed Electric Field: Fundamentals and Effects on the Structural and Techno-Functional Properties of Dairy and Plant Proteins
2022
Dairy and plant-based proteins are widely utilized in various food applications. Several techniques have been employed to improve the techno-functional properties of these proteins. Among them, pulsed electric field (PEF) technology has recently attracted considerable attention as a green technology to enhance the functional properties of food proteins. In this review, we briefly explain the fundamentals of PEF devices, their components, and pulse generation and discuss the impacts of PEF treatment on the structure of dairy and plant proteins. In addition, we cover the PEF-induced changes in the techno-functional properties of proteins (including solubility, gelling, emulsifying, and foamin…
Impact of gadolinium on the structure and magnetic properties of nanocrystalline powders of iron oxides produced by the extraction-pyrolytic method
2020
The work has been done in frame of the TransFerr project.

Pēdējais Pinguicula alpina L. paraugs no Staburaga
1961
LU Muzeja Botānikas un mikoloģiju kolekciju herbārijā glabājas vairāki alpu kreimules herbāriji, kas ievākti gan Igaunijā, gan Latvijā. Auga vienīgā dabiskā augtene Latvijā bija Staburags, kas tika apludināts līdz ar HES būvniecību. Vēlākos gados tā bija atrodama arī Raunas Staburagā. Alpu kreimules paraugi LU Muzejā glabājas Herbarium Latvicum (RIG II), Herbarium Balticum (RIG I), Herbarium Lakshewitzi (RIG III) un Jāņa Ilstera herbārijā. Herbarium Latvicum glabājas pēdējais uz Staburaga Botāniķes Gaidas Ābeles (dz. 1931. gadā) ievāktais paraugs.
Characterization of crystalline structure and morphology of Ga2O3 thin film grown by MOCVD technique
2017
Growth of gallium oxide thin film was realized with MOCVD on (0001) sapphire substrate. Structural and compositional properties of thin film were studied employing trimethylgallium and water as precursors, carrier gases were H2 and N2. Obtained film is polycrystalline and predominantly consisted of (201) oriented β-Ga2O3. Sample exhibited blue luminescence which is attributed to oxygen vacancies. H2 gas proved to have beneficial effect on film quality and overall growth process.
