Nanowire lithography (NWL) uses nanowires (NWs), grown and assembled by chemical methods, as etch masks to transfer their one-dimensional morphology to an underlying substrate. Here, we show that ...SiO2 NWs are a simple and compatible system to implement NWL on crystalline silicon and fabricate a wide range of architectures and devices. Planar field-effect transistors made of a single SOI-NW channel exhibit a contact resistance below 20 kOmega and scale with the channel width. Further, we assess the electrical response of NW networks obtained using a mask of SiO2 NWs ink-jetted from solution. The resulting conformal network etched into the underlying wafer is monolithic, with single-crystalline bulk junctions; thus no difference in conductivity is seen between a direct NW bridge and a percolating network. We also extend the potential of NWL into the third dimension, by using a periodic undercutting that produces an array of vertically stacked NWs from a single NW mask.
Drawing on broad research, this study explores the different social and theatrical masking activities in England during the Middle Ages and the early 16th century. The authors present a coherent ...explanation of the many functions of masking, emphasizing the important links among festive practice, specialized ceremonial, and drama. They elucidate the intellectual, moral and social contexts for masking, and they examine the purposes and rewards for participants in the activity. The authors' insight into the masking games and performances of England's medieval and early Tudor periods illuminates many aspects of the thinking and culture of the times: issues of identity and community; performance and role-play; conceptions of the psyche and of the individual's position in social and spiritual structures. Masks and Masking in Medieval and Early Tudor England presents a broad overview of masking practices, demonstrating how active and prominent an element of medieval and pre-modern culture masking was. It has obvious interest for drama and literature critics of the medieval and early modern periods; but is also useful for historians of culture, theatre and anthropology. Through its analysis of masked play this study engages both with the history of theatre and performance, and with broader cultural and historical questions of social organization, identity and the self, the performance of power, and shifting spiritual understanding.

Porous polyurethane films with well-ordered pores were prepared using polystyrene microspheres as a template, and the surface pore sizes were tuned using a new upside-down (USD) method. After ...polystyrene microspheres were self-assembled on a substrate and the voids between microspheres were infiltrated with a polyurethane prepolymer solution, the samples were placed upside down to allow the prepolymer solution to flow back before it was solidified. The surface pore sizes of the porous films were tuned by changing the time in which the samples were placed upside down. Using microspheres of the same size, we prepared porous polyurethane films with surface pore sizes ranging from 32 to 87% of the templating microsphere size.
This book pursues an enduring puzzle that has stumped historians for centuries and seduced novelists and filmmakers down to this day. Who was the man who wore an iron mask and was kept in prison for ...years during the reign of the Sun King, Louis XIV? Paul Sonnino brilliantly traces his decade-long quest to solve the mystery.
In The Encoded Cirebon Mask: Materiality, Flow, and Meaning along Java's Islamic Northwest Coast, Laurie Margot Ross situates masks and masked dance in the Cirebon region of Java (Indonesia) as an ...authentic expression of Islam by analyzing the objects themselves.
Cro is unstoppable. First the masked rapper conquered the batch heat in Germany, Austria and Switzerland with his single\ "Dream\." Then his new album\ "Melodie\" in all three countries also made it ...to one. At a festival performance, the mid-twenties from Stuttgart tell us how he deals with success and whether he still has unfulfilled dreams.
Cro ist nicht zu stoppen. Erst eroberte der maskierte Rapper die Chartspitze in Deutschland, Österreich und der Schweiz mit seiner Single "Traum". Dann schaffte es auch sein neues Album "Melodie" in allen drei Ländern auf die Eins. Bei einem Festival-Auftritt erzählt uns der Mittzwanziger aus Stuttgart, wie er mit dem Erfolg umgeht und ob er noch unerfüllte Träume hat.

Rizik od zaraze jedan je od najvažnijih aspekta bolesti COVID-19 koji zabrinjava zdravstvene djelatnike na prvoj liniji. Znanje o načinu prijenosa SARS-CoV-2 još uvijek je nedovoljno. Međutim, čini ...se da je izravan kontakt, s osobe na osobu, glavni put prijenosa zaraze. Sekundarni prijenos je također moguć, pri čemu je veća kontaminacija zabilježena u jedinicama za intenzivnu njegu bolesnika za razliku od općih bolničkih odjela. Smatra se da je rizik od prijenosa infekcije zaraznim aerosolom koji se širi kroz ventilacijske sustave vrlo nizak. Skrining i trijaža svih osoba koje dolaze u zdravstvenu ustanovu od presudne su važnosti kako bi se spriječilo brzo širenje virusa među bolničkim osobljem i pacijentima. Preporuke o mjerama za suzbijanje širenja infekcija koje se prenose zrakom u zdravstvenim ustanovama razlikuju se ovisno o lokaciji, ali ih treba univerzalno primjenjvati kod svih postupaka kod kojih se stvara aerosol. Kirurške ili respiratorne maske trenutno su najvažnija oprema koja bi trebala biti rezervirana za zdravstveno osoblje. Obje vrste maski potrebno je koristiti u kombinaciji s drugom osobnom zaštitnom opremom. Pacijente s COVID-19 treba grupirati, a samo pacijente koji se podvrgavaju postupcima koji stvaraju aerosol treba smjestiti u posebne sobe za izolaciju.
Za suvremene Grke: “Karneval bez maski je kao kruh bez brašna”. Maske su tradicionalno bile važan dio religijskih svetkovina u antičkoj i modernoj Grčkoj, osobito onih vezanih uz tijek agrikulturne ...godine, ponajprije proljetni ekvinocij, dok moderna sezona karnevala prije perioda Korizme nije zamijenila antičke svetkovine posvećene Dionizu, koji je uz Demetru, bio ključno božanstvo poljoprivrednika. Maskiranje se prakticiralo i početkom svibnja, prije žetve te kasnije prije sjetve i sredinom zime. Prema jednom od antičkih izvora, Pauzaniji, svećenik za vrijeme godišnjih rituala posvećenih Demetri stavlja masku božice i udara zemlju štapom kako bi probudio sile podzemlja i zemlju učinio plodnom.
Značajke antičkih i suvremenih svetkovina pod maskama u članku se uspoređuju s naglaskom na dodirnim točkama. Istražuje se snaga maski općenito, kao npr. u vezi s Meduzom i drugim antičkim mitskim likovima te upućuje na važnost maskiranja i životinjskih maski u obredima prijelaza
