“…The diffraction peaks at 29.79 o , 33.52 o , 49.19 o , 58.19 o corresponding to the (222), (400), (440), (622) diffraction planes, respectively, are the characteristic peaks of the cubic phase of the Yb2O3. These peaks also match well with the JCPDS: 87-2374 for standard cubic phase of Yb2O3 as well as the reported literature[49,466,470]. Broad peaks indicate that the particles are of nanosize.…”

Μετά την δήλωση του Richard Feynman το 1959 "Υπάρχει άφθονος χώρος στο κατώτατο σημείο", πυροδοτήθηκε μια εκτεταμένη έρευνα για την άμεσο χειρισμό των ατόμων και μετά από αρκετές δεκαετίες έρευνας γεννήθηκε μια νέα τεχνολογία, η οποία ονομάζεται "Νανοτεχνολογία". Αυτή η νέα τεχνολογία αποτελεί μια πολύ ευρεία περιοχή, συμπεριλαμβανομένων των τομέων της επιστήμης, όπως η επιστήμη επιφανειών, η οργανική χημεία, η μοριακή βιολογία, η φυσική των ημιαγωγών, η μοριακή μηχανική κ.ο.κ. Η νανοτεχνολογία είναι η μηχανική των λειτουργικών συστημάτων στη μοριακή κλίμακα και διαθέτει την ικανότητα να κατασκευάζει υλικά από προσεγγίσεις από κάτω προς τα πάνω και από πάνω προς τα κάτω. Είναι μία από τις σημαντικότερες και δυναμικότερες τεχνολογίες λόγω των πολυάριθμων εφαρμογών της, όχι μόνο στους τομείς της ηλεκτρονικής, της οπτικής, της κατάλυσης, της περιβαλλοντικής μηχανικής και της αεροδιαστημικής αλλά και της βιομηχανίας καλλυντικών, της ιατρικής, της φαρμακοβιομηχανίας και της μηχανικής κλπ. Γενικά, η νανοτεχνολογία είναι η τεχνολογία σχεδιασμού, κατασκευής και εφαρμογών νανοδομών και νανοϋλικών που βασίζεται στη θεμελιώδη κατανόηση των φυσικών ιδιοτήτων και φαινομένων.Ο ημιαγωγός είναι ένα υλικό που έχει μια ηλεκτρική αγωγιμότητα μεταξύ ενός αγωγού και ενός μονωτή. Όταν το μέγεθος των ημιαγώγιμων υλικών μειωθεί στην περιοχή της νανοκλίμακας, οι φυσικές και χημικές ιδιότητές τους αλλάζουν δραστικά λόγω της μεγάλης επιφάνειας τους ή του κβαντικού μεγέθους. Έτσι, τα νανοϋλικά ημιαγωγών κατέχουν ιδιαίτερη θέση στη νανοτεχνολογία, δεδομένου ότι αυτά τα νανοϋλικά δεν χρησιμοποιούνται μόνο για την κατασκευή οπτοηλεκτρονικών συσκευών και συστημάτων υψηλής απόδοσης, αλλά και για βιολογικές και περιβαλλοντικές εφαρμογές. Λόγω διαφόρων υψηλών τεχνολογικών εφαρμογών, έχουν γίνει εκτενείς ερευνητικές εργασίες για τη σύνθεση, τα χαρακτηριστικά και τις εφαρμογές των ημιαγώγιμων νανοϋλικών. Ωστόσο, είναι ακόμα επιθυμητό να παρασκευαστούν ημιαγώγιμα νανοϋλικά με πρόδρομες ενώσεις φιλικές προς το περιβάλλον και με διαδικασίες που να δίνουν διάφορα μεγέθη και μορφολογίες με σκοπό την αποτελεσματική χρήση τους σε συγκεκριμένες εφαρμογές.Η διδακτορική αυτή εργασία επικεντρώνεται στη σύνθεση, τον χαρακτηρισμό και τις περιβαλλοντικές εφαρμογές μιας ποικιλίας ημιαγώγιμων νανοϋλικών. Τα ημιαγώγιμα νανοϋλικά που μελετήθηκαν σε αυτή τη διατριβή είναι το οξείδιο του ψευδαργύρου (ZnO), το ZnO εμπλουτισμένο με οξείδιο του Σαμαρίου (Sm2O3), το ZnO εμπλουτισμένο με άργυρο (Ag), νανοσωλήνες άνθρακα με ZnO, οξείδιο του χαλκού (CuO), οξείδιο του Υττερβίου (Yb2O3), οξείδιο του νικελίου (NiO) και υποανθρακικό βισμούθιο (Bi2O2CO3).

“…Optical-based technology is attractive due to its wireless nature. However, they lack the necessary accuracy for credible measurements and are not applicable for measurements in many important sections, such as the turbine blades, where line of sight cannot achieve [355,356]. Accordingly, new sensors with the capability of in situ and real-time monitoring the temperature and pressure in gas turbine engines are highly demanded.…”

Since the 1960s, a new class of Si-based advanced ceramics called polymer-derived ceramics (PDCs) has been widely reported because of their unique capabilities to produce various ceramic materials (e.g., ceramic fibers, ceramic matrix composites, foams, films, and coatings) and their versatile applications. Particularly, due to their promising structural and functional properties for energy conversion and storage, the applications of PDCs in these fields have attracted much attention in recent years. This review highlights the recent progress in the PDC field with the focus on energy conversion and storage applications. Firstly, a brief introduction of the Si-based polymer-derived ceramics in terms of synthesis, processing, and microstructure characterization is provided, followed by a summary of PDCs used in energy conversion systems (mainly in gas turbine engines), including fundamentals and material issues, ceramic matrix composites, ceramic fibers, thermal and environmental barrier coatings, as well as high-temperature sensors. Subsequently, applications of PDCs in the field of energy storage are reviewed with a strong focus on anode materials for lithium and sodium ion batteries. The possible applications of the PDCs in Li-S batteries, supercapacitors, and fuel cells are discussed as well. Finally, a summary of the reported applications and perspectives for future research with PDCs are presented.

Rare earth oxides (REOs) are deemed important from both industrial implementation and research insight perspectives. One of the most conspicuous attributes of REOs is sensing, which contributes significantly to the development of diversified and robust systems of sensors and detector devices. However, there has not been any organized review that has pointed out critical insights from the sensor, detector, and electronic device perspectives that can invoke further studies to investigate the prospective and commercially relevant areas to date. To address this limitation, this review undertakes a focused report approach. From this concise yet comprehensive review, it has been prominent that the most significant contributions to the sensing and detecting fields by the REOs are in electrochemical, temperature, humidity, radiation, gas, and biosensors. Moreover, in terms of electronic device development, REOs have had a significant impact on memory devices, metal oxide semiconductors, dielectric materials, capacitors, energy storage devices, and so on. Furthermore, one of the key findings of the study is that the REOs have flexible doping (e.g., Er3+, Yb3+, Y3+, etc.) capability combined with other host materials such as HfO2 film, SiO2 stacks, TiO2, SnO2 nanostructures, etc., which will likely make REO-based electrochemical sensor and biosensor development the most promising sector in the coming years. Despite the impressive aspects, biocompatibility issues in several biological and biomedical systems along with the hygroscopic nature of REOs in electronic devices remain as concerns. However, these issues can be addressed by the advancement of intricate technologies such as targeted manipulation of the electronic configuration of REOs, multifarious doping experiments to obtain alternative mechanisms, etc. to obtain superior biocompatibility, and device development systems that are noninvasive to the environment. From the commercialization front, memory devices and energy storage devices will be the focusing points for large-scale investors due to improved mechanical (i.e., Young’s modulus, intrinsic stress, etc.) and electrical (i.e., high dielectric constant, resistivity, relative permittivity, etc.) properties, while REO-based metal oxide semiconductor and capacitor development is likely to be research-oriented for the next few years before making the eventual move to futuristic applications at a large industrial scale. In short, this review reports a substantial number of relevant studies that will pave the way for further experimental and computational investigations on REOs and their sensor, detector, and electronic device aspects.
