Humidity-enhanced sub-ppm sensitivity to ammonia of covalently functionalized single-wall carbon nanotube bundle layers
2017
International audience; A low-cost method for carbon nanotubes (CNTs) network production from solutions on flexible polyethylene naphthalate substrates has been adopted to prepare high quality and well characterized SWCNT bundle layers to be used as the active layer in chemiresistor gas sensors. Two types of SWCNTs have been tested: pristine SWCNTs, deposited from a surfactant solution, and covalently functionalized SWCNTs, deposited from a dimethyl-acetamide solution. The humidity effects on the sensitivity of the SWCNTs network to NH3 have been investigated. The results show that relative humidity favors the response to NH3, confirming recent theoretical predictions. The COOH-functionaliz…
Propagation of Artemisia Arborescens L. by stem-cutting: Adventitious root formation under different conditions
2012
Artemisia arborescens L. has gained a strong importance worldwide due to its many industrial uses and it has been recently considered as ornamental plant. A major constraint to its widespread cultivation is represented, by far, by the scarce availability of high-quality plant material for field establishment; hence, development of a fast and effective methods for its vegetative propagation is needed. An experiment was conducted to assess the effects of different harvest periods, NAA, and rooting substrates on rooting of stem cuttings of A. arborescens. Semi hardwood cuttings were collected from wild plants in February, April, and November. Half of the material was treated with 0.4% NAA and …

Musica nel "Poliorama Pittoresco"
2010
Il saggio rintraccia ed analizza i contributi a carattere musicale comparsi nella rivista napoletana "Poliorama pittoresco", uscita dal 1836 al 1860. Accanto a profili biografici e ad articoli encomiastici (specialmente su Rossini), la rivista pubblica interessanti articoli dedicati alla musica popolare. In particolare nel saggio vengono analizzati due contributi sui Viggianesi, musicisti ambulanti giunti dalla Basilicata in tutta Europa ed anche in America, e un importante testo di Giuseppe Regaldi del 1847 dedicato alla canzone napoletana, ricco di preziose informazioni di prima mano (tale testo è riportato per intero in appendice).

2017
Właśnie w czasach oszczędności finansowych oraz postępującego procesu ekonomizacji kultury jest ważnym fakt, aby filolodzy angażowali się również kulturowo i politycznie dla swoich autorów, nad którymi sprawują opiekę naukową, oraz w zakresie tematyki dzieł. Artykuł opisuje przygotowywaną wystawę w Domu Literatury im. Johann-Heinrich-Voß'a w Penzlin, w miejscowości, w której Voß otrzymał pierwsze impulsy rozwoju. Voß wyjaśnia propozycje szkolno-pedagogiczne, w pewnym sensie skromne warsztaty literackie, które zostaną zrealizowane w ramach wystawy stałej zatytułowanej "Johann Heinrich Voß. Grek z Mecklenburii".
Bezpośrednie wytwarzanie energii elektrycznej z oleju napędowego
2016
Ze względu na stale wzrastające zapotrzebowanie na energię elektryczną poszukiwane są coraz to nowsze rozwiązania, pozwalające na sprostanie temu wyzwaniu. W ostatnich latach oprócz tradycyjnych metod wytwarzania energii coraz dynamiczniej rozwija się energetyka niekonwencjonalna. Przykładem takiego rozwiązania jest stosowanie ogniw paliwowych, głównie ze względu na ich wysoką sprawność. Ogniwa te przetwarzają energię chemiczną bezpośrednio na energię elektryczną, z pominięciem procesu spalania paliwa. Najczęściej zasilane są wodorem, jednak problemy z jego przechowywaniem wymuszają poszukiwanie innych paliw. Ponadto ogniwa paliwowe mogą stanowić dodatkowe/zapasowe źródło energii elektryczn…
Le "vrai portrait" du Grand Comte Roger. De Florence à la Sicile: aux origines d'une équivoque
2006
Partendo da due dipinti pressoché identici del XVII secolo conservati a Patti (ME) e Troina (EN), che raffigurano il ritratto ideale del Gran Conte Ruggero Hauteville, protagonista della liberazione della Sicilia dal dominio islamico, se ne è riconosciuto il modello in un dipinto di Cristofano Allori firmato e datato 1590, oggi agli Uffizi ma proveniente dalla Badia Fiorentina, avente per soggetto il Marchese Ugo di Toscana. Il saggio propone inoltre di riferire le opere siciliane al medesimo pittore e alla comune committenza del vescovo Vincenzo Napoli (+1648). Starting from two almost identical paintings from the 17th century preserved in Patti (ME) and Troina (EN), which depict the ideal…
Sensory Organ Investment Varies with Body Size and Sex in the Butterfly Pieris napi
2021
Simple Summary Pollinating insects rely on a range of senses such as vision, olfaction, gustation, and mechanosensation to utilise, locate, and fly between floral resources. The size of different sensory organs determines their sensitivity and provides an indication of their relative importance—larger organs can enhance sensitivity by increasing the number or size of sensing structures. However, increasing the relative size of an organ would require additional energy for developing and maintaining it. This likely leads to a trade-off between the energy invested into different sensory systems within individuals. To explore how the size of the sensory organs vary with body size in insect poll…
