In this doctoral work, the kinetics of carotenoid stability as a function of the food chain will be investigated. The main raw material to be studied is Hokkaido pumpkin (Cucurbita maxima Duchesne ssp.) due to its complex carotenoid profile yet very few studies in the literature. This would be beneficial in optimizing the extraction process of carotenoids from pumpkins as natural colorants in food products. In addition, carotenoids are also ...

Computational chemistry is often used to assess reaction mechanisms qualitatively. Catalytic reactions in organometallic chemistry are one frequent area of application – as experimental data can be hard to acquire. Still quantitative predictions of reactivity, i.e. computational kinetics studies of catalysis, are harder to perform, as they require very accurate electronic structure methods. However such calculations are now starting to be ...

The main objectives of this PhD project are to study the reaction kinetics and mass transfer efficiency of different novel solvent extraction systems for actinide separations, and to investigate how the efficiency of solvent extraction processes can be influenced by changing the contact time in a centrifugal contactor. The current lack of reliable experimental data makes is difficult to define suitable process parameters, and optimize ...

The aim of the work will be to gain quantitative insight into catalytic reaction mechanisms using computation. One possible target system will be the Suzuki-Miyaura cross-coupling of boronates with aryl halides. Many existing experimental and computational studies have considered this reaction, but there still remain insignificant areas where improved understanding would be highly beneficial. After an extensive literature review, the ...

In a biomimetic approach,we aim to create hierarchical multi-functionalone-, two- and three-dimensional structures with controlled long-range order through self-assembly of multifunctional rodlike nanoparticles. To achieve this, we will modify the surface of ribbon-like cellulose nanocrystals at their three distinct surface functionalities: primary and secondary hydroxyl groups on the lateral surfaces and aldehydes at the extremities. These ...

The orbital angular momentum states have been studied in the regime of Classical and Quantum Optics [1]. However, recently Mendonca et al. have predicted the theoretical foundations of intense Laser beam having orbital angular momentum state for Laser-Plasma interaction [2]. It exhibits paradigmatic alteration of Inverse Faraday’s effect [3]. The orbital angular momentum states are being studied for plasma vortices [4]. In this regard, ...

The amalgamation of technology with biology has resulted in a significant improvement both in the quality and the extent of human lifespan. This is more than evident in the current COVID‑19 situation when hospitals and pharmaceutical industry are able to rapidly test millions of people, provide intensive care to those in critical condition and accelerate research to screen for vaccines, thanks to the support provided by technology. However, ...

Transitioning towards food systems favourable for both human health and environmental sustainability has been recently identified as an immediate challenge. In this context, a significant increase in consumption of plant-based foods (e.g. cereals, fruits, legumes, nuts, vegetables) is being strongly promoted to improve health and environmental benefits. Consequently, the development of safe and nutritious food products from ...
