Porous metal-organic materials (MOMs) are assembled through coordination between two types of building units, metal or metal-containing nodes and organic linkers. Metal-organic frameworks (MOFs) have 3-D infinite structures and are especially known for high porosity and enormous surface area, leading to diverse applic…
Few-layer graphene has been prepared by electrochemical intercalation of graphite cathode using Na+/\ndimethyl sulfoxide complexes as intercalation agent. By adding thionin acetate salt into the electrolyte,\nthe exfoliated graphite is stabilized and further exfoliated into few-layer graphene. Raman and X-ray\nphotoel…
Ova disertacija se bavi proračunom stanja neutralnog ekscitona u\npoluprovodničkim nanotačakama (kvantnim tačkama) i nanoprstenovima (kvantnim\nprstenovima) i modelovanjem njihovih optičkih osobina. Neutralni eksciton je\nkvazičestica koja predstavlja vezano stanje elektrona i šupljine izmeĎu kojih postoji\nprivlačna…
This paper introduces the mechanism and structure of shape memory polyurethane materials,and characteristic parameters and associated mathematical models for describing the behaviour of the thermally shrinkable polymeric materials.Recent progress is reviewed on the shape memory polyurethane materials,covering phase se…
Sodium-sulfur batteries,sodium-nickel chloride batteries and sodium-air batteries are collectively called sodium batteries.These batteries use metallic sodium as the anode material and realize electrochemical processes through the transportation of sodium ions and electrons.This paper reviews the research and developm…
Nel lavoro si sono determinate quali soluzioni adottare per incrementare con successo la durata degli utensili in un processo di maschiatura a rullare basandosi sull'utilizzo di utensili dalla geometria opportuna, sulla scelta del rivestimento adatto, e mediante formulazione di un lubrificante ad alte prestazioni. Cio…
L'attivita ha visto svolgersi varie macinazioni ad alta energia, successivamente alla macinazione le polveri attivate sono state sinterizzate, con o senza l'aggiunta di fibre di SiC Hi-Nicalon, sono state eseguite anche prove ad ossidazione. Successivamente i prodotto ossidati e non stato caratterizzati microstruttura…
L'oggetto della tesi e stato lo studio, tramite modelli numerici e prove sperimentali, di un innovativo sistema per il riscaldamento a cuore di billette di materiali non ferrosi. Il sistema ideato dal laboratorio di elettrotermia si basa sull'induzione di correnti indotte ottenuta tramite il movimento relativo di un s…
Η παρούσα διπλωματική εργασία αποτελεί μια έρευνα που πραγματοποιήθηκε με εφαλτήριο την ανάγκη διαρκούς ενημέρωσης των μηχανικών επί των τεχνολογικών εξελίξεων. Το κτήριο που προτείνεται, μια Smart Materials Library, στεγάζει ένα συγκεντρωτικό αρχείο έξυπνων υλικών, μια ανοιχτή βιβλιοθήκη που προωθεί την διεπιστημονικ…
Isocitrate dehydrogenase (IDH1), an enzyme involved in the conversion of isocitrate into α-ketoglutarate, is an important enzyme in the citric acid cycle—a primary source of energy for the human body. A mutation in IDH1 disrupts its structure and overall functionality, leading to the high probability of developing agg…
Este trabalho demonstra o uso da fotopolimerização via absorção de dois fótons na produção de
The Gibbs free energies for KClO3 were evaluated in mixed dimethyeformamide (DMF)-H2O solvents at 301.15 K from the experimental solubility measurements. From the experimental the ionic radii ratio of potassium to chlorate ions, the total free energy of the salt is divided into its individual contribution in the mixtu…
Abstract The study of biomolecules and bioparticles has achieved great advances, thus increasing the productivity with upstream improvements. Nowadays, downstream processes are the bottleneck in the production of some biopharmaceuticals, a change from the previous years' scene. Current purification platforms will reac…
Composites manufactured with networks of carbon nanotubes (CNTs) exhibit piezoresistivity. These composites have tremendous potential for integrated and high sensitivity strain sensing. However, modeling CNT composite piezoresistivity remains a challenge. Prevailing approaches rely on resistor network and fiber reorie…
Some critical remarks are made regarding a series of works by V.K. Mukhomorov dealing with polarons and oscillatory and rotational spectrum of a large-radius bipolaron near a subsidiary minimum corresponding to its two-center configuration. It is shown that V.K. Mukhomorov's conclusion that by varying the bipolaron fu…

Abstract Water treeing occurs when an AC voltage is applied to an electrical insulation system such as those in power cables and power apparatus. From a practical viewpoint, research on water treeing has mostly been performed under high‐frequency AC voltage application. However, power cables and power apparatus are al…
