Liquid metal enabled pump
No full textSmall-scale pumps will be the heartbeat of many future micro/nanoscale platforms. However, the integration of small-scale pumps is presently hampered by limited flow rate with respect to the input power, and their rather complicated fabrication processes. These issues arise as many conventional pumping effects require intricate moving elements. Here, we demonstrate a system that we call the liquid metal enabled pump, for driving a range of liquids without mechanical moving parts, upon the application of modest electric field. This pump incorporates a droplet of liquid metal, which induces liquid flow at high flow rates, yet with exceptionally low power consumption by electrowetting/deelectrowetting at the metal surface. We present theory explaining this pumping mechanism and show that the operation is fundamentally different from other existing pumps. The presented liquid metal enabled pump is both efficient and simple, and thus has the potential to fundamentally advance the field of microfluidics.Shi-Yang Tang, Khashayar Khoshmanesh, Vijay Sivan, Phred Petersen, Anthony P.

Electrochemically induced actuation of liquid metal marbles
No full textControlled actuation of soft objects with functional surfaces in aqueous environments presents opportunities for liquid phase electronics, novel assembled super-structures and unusual mechanical properties. We show the extraordinary electrochemically induced actuation of liquid metal droplets coated with nanoparticles, so-called “liquid metal marbles”. We demonstrate that nanoparticle coatings of these marbles offer an extra dimension for affecting the bipolar electrochemically induced actuation. The nanoparticles can readily migrate along the surface of liquid metals, upon the application of electric fields, altering the capacitive behaviour and surface tension in a highly asymmetric fashion. Surprising actuation behaviours are observed illustrating that nanoparticle coatings can have a strong effect on the movement of these marbles. This significant novel phenomenon, combined with unique properties of liquid metal marbles, represents an exciting platform for enabling diverse applications that cannot be achieved using rigid metal beads
Tang Code, Tang Rite, and Other Manuscripts of Tang Dynasty
Get PDFIn the present paper, the author gives the preliminary reports on three newly found Tang 唐 official documents, pointing out their important value, and offering the all texts for further studies.1. In Tunhuang and Turfan Documents concerning Social and Economic History I. Legal Texts (Tokyo 1978-1980), Professors T. Yamamoto, O. Ikeda, and M. Okano published the joined texts of O. 5098 and O. 8099 from Otani collection. They identified the fragments with the Section on Violence and Robbery of the Tang Code (唐律), and pointed out the article comes from the Yonghui 永徽 or Chuigong 垂拱 Code according to the Zetian 則天 characters used in the Buddhist text on the verso. The author joins another fragment based on an old photograph of the Turfan document preserved in the Lüshun Museum (旅順博物館). The new text contains one different article from the printed text after the Song 宋 dynasty.2. Among the Dunhuang 敦煌 manuscripts in the National Library of China in Beijing, there is a good copy of the Tang Rite (唐礼) in high Tang characters (No. zhou 周 70A). It contains the text corresponding to the Da Tang Kaiyuan li 大唐開元礼, vol. 37: “Huangdi shixiang yu Taimiao 皇帝時享於太廟”. It is the first time to find the book in Dunhuang or Turfan manuscripts.3. In his Dunhuang Turfan Tangdai fazhi wenshu kaoshi 敦煌吐魯番唐代法制文書考釈, Liu Junwen thought the document of zhou 51 should be the Regulations of the Regional Military Organization. But the form of the original document could not conform to the Tang Regulations, so the author refutes his view and thinks that it is an official document relating to the beacon of the military fortress in the area of Dunhuang or Turfan.journal articl

O trabalho foi desenvolvido com base em pesquisas e informações fornecidas pela Dayrane Souza, Gerente de Trade Marketing da empresa Mondelēz Brasil. O aumento da preocupação em relação a saudabilidade e a alimentação dos pais e mães com as crianças resultou na queda do consumo de refrescos em pó. Por isso, o objetivo principal do projeto é a elaboração de uma campanha para aumentar a visibilidade dos consumidores e possíveis consumidores em relação à marca Tang, a variedade e praticidade que o produto oferece, o novo produto para misturar com leite e a nova fórmula de seu produto principal, mais saudável e ainda saboroso no verão de 2023The course final paper, called "Integrated Communication Project" (PIC), of the Social Communication - Publicity and Advertising course at the Pontifical Catholic University of São Paulo (PUC), was prepared and carried out by the fictitious agency SPOT, for the powdered soft drink brand Tang The work was developed based on research and information provided by Dayrane Souza, Trade Marketing Manager at the company Mondelez Brazil. The increased concern regarding the healthiness and nutrition of parents with their children has resulted in a drop in the consumption of powdered soft drinks. Therefore, the main objective of the project is to develop a campaign to increase the visibility of consumers and potential consumers in relation to the Tang brand, the variety and practicality that the product offers, the new product to mix with milk and the main product new formula, healthier and still tasty in the summer of 202
Liquid metal marbles
No full textLiquid metal marbles that are droplets of liquid metal encapsulated by micro- or nanoparticles are introduced. Droplets of galinstan liquid metal are coated with insulators (including Teflon and silica) and semiconductors (including WO3, TiO2, MoO3, In2O3 and carbon nanotubes) by rolling over a powder bed and also by submerging in colloidal suspensions. It is shown that these marbles can be split and merged, can be suspended on water, and are even stable when moving under the force of gravity and impacting a flat solid surface. Furthermore, the marble coating can operate as an active electronic junction and the nanomaterial coated liquid metal marble can act as a highly sensitive electrochemical based heavy metal ion sensor. This new element thus represents a significant platform for the advancement of research into soft electronics
Reinventing the Pre-Tang Tradition: Compiling and Publishing Pre-Tang Poetry Anthologies in Sixteenth-Century China
No full textAbstract
This article examines how the making of pre-Tang poetry anthologies in sixteenth-century Ming China led to a reinvention of the pre-Tang poetic tradition. From the Zhengde period 正德 (1506–21) well into the Wanli reign 萬曆 (1573–1620), the compilation and publication of new pre-Tang poetry anthologies saw a dramatic increase, making the anthologizing practices in the 1500s crucial to understanding the pre-Tang tradition. Through a study of paratextual elements (book titles, tables of contents, prefaces, postscripts, etc.) in twenty-two pre-Tang poetry anthologies compiled in the 1500s, this article identifies three types of anthologizing practices. By employing quantitative and network analysis, the author hopes to historicize these practices, investigate the motivations for the anthologies, and explore their citation networks. These anthologizing practices, I conclude, gradually transformed the classification principles of previous anthologies, expanded the scope of canonized anthologies, and established a distinct pre-Tang tradition by the end of the sixteenth century.</jats:p
Influence of semiconducting properties of nanoparticle coating on the electrochemical actuation of liquid metal marble
No full textSemiconducting properties of nanoparticle coating on liquid metal marbles can present opportunities for an additional dimension of control on these soft objects with functional surfaces in aqueous environments. We show the unique differences in the electrochemical actuation mechanisms of liquid metal marbles with n- and p-type semiconducting nanomaterial coating. A systematic study on such liquid metal marbles shows voltage dependent nanoparticle cluster formation and morphological changes of the liquid metal core during electrochemical actuations and these observations are unique to p-type nanomaterial coated liquid metal marbles
Photochemically induced motion of liquid metal marbles
No full textWe demonstrate photochemically induced actuation of liquid metal marbles, which are liquid metal droplets encased in micro/nanoparticles. The WO 3 nanoparticles coated marbles are placed in H2O 2 solution, and their surfaces are illuminated with UV light. The semiconducting WO3 coating behaves as a photocatalyst to trigger a photochemical reaction, generating oxygen bubbles that propel the marble. The actuation of the marbles is investigated under different H2O 2 concentrations, light intensities, and marble dimensions. Equations describing the fundamentals of such actuations are presented.</p
Transitional civic placemaking: dispersed initiatives in changing urban landscapes
Get PDFField trip publication on the theme of "Transitional Civic Placemaking: Dispersed Initiatives in Changing Urban Landscapes" in Athens, Calabria and Freetown (and Yakutsk). Produced by students from MArch/MA by Project Unit 6 and Degree Studios 3 & 7 at the Cass School of Art, Architecture and Design at London Metropolitan University in 2018-19. Tutors: Maurice Mitchell, Bo Tang, Robert Barnes, Sandra Denicke-Poulcher and Jane McAllister.
This booklet summarises the investigations, surveys and speculations of architecture students in Degree Studios 3 and 7, together with Diploma Unit 6 at the CASS. We started the year by immersing ourselves in an urban setting in South Bermondsey which was full of a diverse array of steel and concrete sheds. Exploratory design work focused on the assembly, conversion, adjustment, extension, and/ or re-assembly of existing buildings to better suit the concerns of the existing inhabitants. Students investigated closed boundaries and permeable borders (Sennett, 1998). Out of this investigation emerged speculations which included arcades, a re-purposed canal and high-ceilinged ground floor workshops under multi-storey apartments.
Having practiced on-site research methods and following on from the previous summer scoping study, Civic Edgelands, students undertook field trips to Athens, Freetown, and Calabria in November 2018. All three locations are, or have been, migrant gateways, and transitional settlements for the uprooted and offer new opportunities for urban dwelling to their occupants: old, new and those just passing through
