One-dimensional CdS nanostructures: synthesis, properties, and applications
No full textOne-dimensional (1D) semiconductor nanostructures are of prime interest due to their potential in investigating the size and dimensionality dependence of the materials' physical properties and constructing nanoscale electronic and optoelectronic devices. Cadmium sulfide (CdS) is an important semiconductor compound of the II-VI group, and its synthesis and properties have been of growing interest owing to prominent applications in several fields. This article provides a comprehensive review of the state-of-the-art research activities that focus on the rational synthesis, novel properties and unique applications of 1D CdS nanostructures in nanotechnology. It begins with the rational design and synthesis of 1D CdS nanostructures, and then highlights a range of unique properties and applications (e.g. photoluminescence, cathodoluminescence, electrochemiluminescence, photocatalysis, lasers, waveguides, modulators, solar cells, field-effect transistors, photodetectors, field-emitters, and nanogenerators) associated with them. Finally, the review is concluded with the author outlook of the perspectives with respect to future research on 1D CdS nanostructures
La policía bonaerense en la primera década independiente: el bando del alcalde de la hermandad del partido de San Fernando de Buena Vista y puerto de Las Conchas (1818)
No full textAs part of an investigation focused on the police commandments issued in Buenos Aires between 1810 and 1821, we presented the bando published in San Fernando de Buena Vista on February 8, 1818, by the alcalde de la Hermandad José Joaquín de La Madrid. Based on unpublished documents from the Archivo General de la Nación, acts of the extinct cabildo of Buenos Aires, orders and instructions to the alcaldes de la Hermandad, newspapers and contemporary testimonies, we turn first to the author and then study the text itself, examining aspects of their development and promulgation, publication, diplomatic description and normative content, appeal and application. En el marco de una investigación centrada en los mandamientos que en materia de policía se dieron en Buenos Aires entre 1810 y 1821, presentamos el bando expedido en San Fernando de Buena Vista el 8 de febrero de 1818, por el alcalde de la Hermandad del partido de San Fernando de Buena Vista y puerto de Las Conchas, José Joaquín de La Madrid. Sobre la base de documentación inédita del Archivo General de la Nación, los acuerdos del extinguido cabildo de Buenos Aires, las órdenes e instrucciones dadas para los alcaldes de la Hermandad, periódicos y testimonios de contemporáneos, nos ocuparemos en primer lugar de su autor, para luego estudiar el texto del bando propiamente dicho, analizando aspectos relacionados con su elaboración y promulgación, publicación, descripción diplomática y contenido normativo, apelación y aplicación.
Summer Workshop on Physics, Mathematics, and All That Quantum Jazz
No full textThis book is a collection of contributions from a Summer Workshop on Physics, Mathematics, and All That Quantum Jazz . Subjects of the symposium include quantum information theory, quantum annealing, Bose gases, and thermodynamics from a viewpoint of quantum physics. Contributions to this book are prepared in a self-contained manner so that readers with a modest background may understand the subjects
An Approach to Easy Construction of 3D Space and Its Implementation
No full textThis paper presents “easy-three,“ a simplified library for creating 3D spaces based on Three.js. By abstracting complex configurations, the library makes it easy for beginners to design 3D graphics with minimal code. It eliminates the need for dedicated software, requiring only a text editor and web browser. Easy-three is particularly effective in educational settings, where it facilitates interactive and accessible 3D programming lessons. Future developments will focus on expanding features and supporting educational use cases.departmental bulletin pape
Le idee invendute di un'umanità all'asta : un'interpretazione di "Bando" nell'opera di Sergio Corazzini
No full textSpesso letta come eccezione d’ironia e vivacità, "Bando" s’inscrive pienamente, invece, nel panorama poetico corazziniano, e ne è l’ideale coronamento, posta com’è a chiudere il "Libro per la sera della domenica", ultima raccolta pubblicata vivente il poeta. La corrosione, ora tutta umana, dell’ambiente dell’asta, le tensioni all’animalità e a un’escatologia dell’abbandono del sé sono i termini più vistosi di questa continuità con l’intera opera di Corazzini, di cui si propone un rapido ma esteso excursus, che si avvale in particolare di un proficuo confronto con il crepuscolarismo brasiliano di Manuel Bandeira. La concitazione dell’asta si ribalta in vana preghiera a passanti disinteressati all’idea in sé, morte, suicidio, prostituzione paiono riemergere, sommersi, da più di un luogo del testo, richiamando esperienze centrali del Corazzini della "Desolazione", delle "Dolcezze" o delle prose. È distinguendo, pur nella difficoltà del contesto lirico, tra un “io che batte l’asta” e un “io poetante” che si perviene alla definizione di un tono duplice: la supplica orante del banditore disperato da un lato, dall’altro la denuncia inesorabile di una crisi, che investe, più che la vendibilità in sé delle idee, il sostanziale disinteresse che esse generano nel potenziale uditorio di offerenti, l’umanità.Generally read as an ironic or playful exception, "Bando", instead, perfectly places itself in Corazzini’s poetical production, and can be considered an ideal achievement of it, also considering its relevant position in conclusion of "Libro per la sera della domenica", the last collection published by the author still alive. The human corruption of the auction milieu, the tensions to bestiality and self-loosing are the most remarkable aspects of this continuity with the rest of Corazzini’s poems, of which is purposed a fast but extended excursus, developed by a dialogue with crepuscular directions of Brazilian modernism, especially expressed by Manuel Bandeira. The agitation of the auction reverses itself in an useless prayer addressed to uninterested people; death, suicide, prostitution seem resurface from more than one verse, recalling the central experiences of Corazzini’s "Desolazione", "Dolcezze" and prose works. Only distin guishing, despite of the difficulty of lyric contest, an "I-auctioneer" and an "I lyricist", it is possible to define a double tone: on the one hand, the oratory plea of the desperate auctioneer; on the other hand, the lyric denunciation of a crisis which attacks, more than the dealing of ideas, their interest for an only potential public of bidders, that is mankind
BN nanospheres as CpG ODN carriers for activation of toll-like receptor 9
No full textFor the first time, we demonstrated BN nanospheres (BNNSs) can interact with biomolecules and deliver unmethylated cytosine-phosphate-guanine oligodeoxynucleotides (CpG ODNs) into cells to activate toll-like receptor 9 (TLR9), which is a very important process for therapy of cancers and allergy diseases
