Theories of gravitation confronted with cosmological observations

Garcia Garcia, Carlos (Date of defense: 2020-11-10)

This thesis studies Dark Energy, a central topic of Modern Cosmology, from different points of view. It covers from models and parametrizations to likelihood approximations for the observations of the Large Scale Structure ...

Thermodynamics and Kinetics of Nucleic Acids Folding

Rissone, Paolo (Date of defense: 2023-04-20)

[eng] This doctoral work investigates nucleic acids' thermodynamic and kinetic properties. The main objective is the characterization of the energetics and the folding mechanisms driving the hybridization of DNA and RNA ...

Towards a better characterization of submicron aerosol in the Mediterranean basin

Via González, Marta (Date of defense: 2023-09-19)

[eng] Atmospheric aerosol is an ensemble of atmospheric pollutants with a severe impact on human health and Earth climate. Particulate Matter (PM) eﬀects vary depending on the composition and size. However, current air ...

Transformation of Nanocrystals in Electrochemical Energy Technologies

Yu, Xiaoting (Date of defense: 2020-06-30)

This thesis focuses on the synthesis of different types of NCs, their application to energy conversion and storage technologies, particularly LIBs, KIBs and DEFCs, and their structural transformation during electrochemical ...

The aim of this Ph.D. thesis is the synthesis and characterization of nanoparticles to understand and optimize their macroscopic properties. The manuscript is divided into seven chapters. Chapter 1 is a general introduction ...

Two dimensional materials based electronic synapses for neuromorphic applications

Shi, Yuanyuan (Date of defense: 2018-07-24)

Electronic machines and computers have experienced a huge development during the last four decades, mainly thanks to the continuous scaling down of the hardware responsible of information processing and storage (i.e. ...

Understanding the measurements and variability of aerosol optical properties in NE Spain

Yus Díez, Jesús (Date of defense: 2022-12-20)

[eng] Atmospheric aerosol particles are key for regulating Earth’s atmosphere processes, and are estimated to present an overall cooling effect on the Earth’s climate. Given the current climate change crisis, and the need ...

Unveiling viral structures by single-molecule localization microscopy

Arista Romero, Maria (Date of defense: 2021-06-28)

Influenza A virus is one of the most outstanding human viruses. The major treatments against influenza are small analogues, monoclonal antibodies and vaccines, however, due to the fast mutation of the seasonal influenza ...

Wide bandgap chalcogenide thin films onto transparent substrates

Salem, Mohamed Ould (Date of defense: 2022-06-02)
