V diplomskem delu je bila proučena fotoizomerizacija 2-aril cinamatov iz termodinamsko stabilnejše E-oblike v Z-izomer z uporabo EnT katalize in vidne svetlobe. Osrednji cilj raziskave je bil optimizirati reakcijske pogoje in preveriti splošno uporabnost metode na strukturno različnih substratih. Preučeni so bili vpli…
V diplomskem delu je bila preučena kontinuirna adsorpcija metilenskega modrega (MB) na kalcijev alginat/grafen oksid (Ca-Alg/GO) hidrogelnih kroglicah v koloni z nasutim slojem. Izvedenih je bilo šest meritev s sistematično variacijo pretoka (Q = 1, 3 in 5 mL/min), začetne koncentracije MB (C0 = 2, 5 in 10 mg/L) in vi…
Laser-generated surface acoustic waves (SAWs) facilitate efficient information processing in modern spintronics and magnonics. The ability to tune the SAW parameters such as the amplitude is crucial to achieve acoustic control over magnonic properties. Such tunability can be achieved in phase-changing magnetic materia…
V diplomskem delu so bili pripravljeni kompozitni hidrogeli na osnovi TEMPOmodificirane nanofibrilne celuloze (TCNF), kalcijevega karbonata (CaCO3) in različnih nanodelcev grafenovega oksida (GO). Cilj naloge je bil preučiti vpliv treh tipov nanodelcev (GOSL12, GOSL38 in GOFL38) ter različnih koncentracij mravljinčne…
The production of composite road pavements requires eco- friendly materials capable of resisting dynamic loads. Utilizing industrial by-products like wet magnetic separation tailings and circulating fluidized bed (CFB) boiler slags addresses both ecological and structural needs. However, the structural performance of…
Las propiedades ópticas y optoelectrónicas de un material suelen describirse a partir de mediciones que promedian la señal de regiones extensas. Ese enfoque sigue siendo indispensable, pero no siempre basta para entender qué parte del sólido controla realmente la respuesta observada. En muchos materiales funcionales,…
NbOx Mott memristors have demonstrated high potential in deep space detection as well as nuclear industries. However, the devices' performance under irradiation exposure remains unexplored. In this work, we investigate the impact of atmospheric neutron irradiation on the characteristics of NbOx memristors and reveal t…
En los últimos años, las celdas solares basadas en perovskitas han emergido como una de las tecnologías fotovoltaicas más prometedoras, al combinar eficiencias de conversión sobresalientes con procesos de fabricación de bajo costo; no obstante, la limitada estabilidad de estos materiales frente a factores ambientales…
Se expone la relevancia de la detección de gases en contextos industriales, ambientales y domésticos, enfatizando que numerosos compuestos gaseosos resultan imperceptibles para los sentidos humanos y, por tanto, representan riesgos significativos. En este trabajo se describen los fundamentos físicos y químicos de los…
Las membranas poliméricas permiten la separación selectiva de gases a temperaturas y presiones más bajas que otras tecnologías existentes, favoreciendo la sostenibilidad. En el presente estudio se sintetizó una membrana a base de una polinorbornendicarboximida fluorada (poli-PhNDI-F) para la separación selectiva de ga…
El cambio climático y la crisis energética han impulsado la búsqueda de soluciones sustentables que reduzcan la dependencia de los combustibles fósiles. En este panorama, el hidrógeno emerge como una alternativa energética clave, pues su combustión produce vapor de agua, lo que lo convierte en una fuente limpia y no c…
The primary objective of this thesis is to investigate the feasibility of cuprous oxide (cuprite) as a competitive platform for microwave-to-optical conversion utilising Rydberg excitons. While the ultimate goal is the simultaneous enhancement of both microwave and optical domains to reach the strong-coupling regime,…

This study numerically investigates the propagation dynamics of methane–oxygen detonation waves in a T-branched pulse detonation tube with a fixed inner diameter of 10 mm. The influence of branch corner radius R on three key aspects is studied including the diffraction-driven re-initiation process, cellular structure…
During the operation of annular rotating detonation combustors, temperature differences commonly develop between the inner and outer walls as a result of wall curvature and non-uniform reactant distribution. In this study, two-dimensional numerical simulations employing an adaptive mesh refinement (AMR) strategy are p…
Aiming at the inadequacy of existing thermal barrier coatings(TBCs) interface models in balancing simplified modeling and realistic morphology characterization, this study constructs a statistically representative rough interface model based on the AR numerical filtering method. By integrating experimental data, a cur…
The influence of susceptor material on the hybrid microwave annealing (HMA) of CoFeB/MgO/CoFeB magnetic tunnel junctions (MTJs) is investigated using p-type Si and poly-SiC susceptors. Under 3 kW HMA, the poly-SiC susceptor enables the MTJs to reach a tunnel magnetoresistance (TMR) of 101.9% within 2.5 min, whereas th…
Amorphous Ga-Zn-O (a-GZO) thin films were synthesized via atomic layer deposition (ALD) and subsequently processed using laser annealing (LA) techniques. The investigation demonstrates that the films maintain their amorphous state across varying laser irradiation energy intensities. This study systematically evaluates…
The thermal infrared emissivity of metallic nanowire networks - the property that makes them candidate low-emissivity transparent electrodes - follows regularities that have resisted physical explanation: a strong wire-diameter dependence with no wire-length dependence, a correlation with sheet resistance that breaks…
Based on the latest experimental insights into the reaction intermediates of boron (B) and boron oxide (B2O3), the existing model has been refined. The revised model consists of four key kinetic processes: decomposition of intermediates, heterogeneous surface reactions of intermediates with environmental oxygen or wat…
