Open Microfluidics

By: Jean Berthier,Kenneth A. Brakke,Erwin Berthier

Open microfluidics or open-surface is becoming fundamental in scientific domains such as biotechnology, biology and space. First, such systems and devices based on open microfluidics make use of capillary forces to move fluids, without any need for external energy. Second, the "openness" of the flow facilitates the accessibility to the liquid in biotechnology and biology, and reduces the weight in space applications. This book has been conceived to give the reader the fundamental basis of open microfluidics. It covers successively The theory of spontaneous capillary flow, with the general conditions for spontaneous capillary flow, and the dynamic aspects of such flows. The formation of capillary filaments which are associated to small contact angles and sharp grooves. The study of capillary flow in open rectangular, pseudo-rectangular and trapezoidal open microchannels. The dynamics of open capillary flows in grooves with a focus on capillary resistors. The case of very viscous liquids is analyzed. An analysis of suspended capillary flows: such flows move in suspended channels devoid of top cover and bottom plate. Their accessibility is reinforced, and such systems are becoming fundamental in biology. An analysis of “rails” microfluidics, which are flows that move in channels devoid of side walls. This geometry has the advantage to be compatible with capillary networks, which are now of great interest in biotechnology, for molecular detection for example. Paper-based microfluidics where liquids wick flat paper matrix. Applications concern bioassays such as point of care devices (POC). Thread-based microfluidics is a new domain of investigation. It is seeing presently many new developments in the domain of separation and filtration, and opens the way to smart bandages and tissue engineering. The book is intended to cover the theoretical aspects of open microfluidics, experimental approaches, and examples of application.

Open-Channel Microfluidics

Fundamentals and Applications

By: Jean Berthier,Ashleigh B Theberge,Erwin Berthier

Open microfluidics, the study of microflows having a boundary with surrounding air, encompasses different aspects such as paper or thread-based microfluidics, droplet microfluidics and open-channel microfluidics. Open-channel microflow is a flow at the micro-scale, guided by solid structures, and having at least a free boundary (with air or vapor) other than the advancing meniscus. This book is devoted to the study of open-channel microfluidics which (contrary to paper or thread or droplet microfluidics) is still very sparsely documented, but bears many new applications in biology, biotechnology, medicine, material and space sciences. Capillarity being the principal force triggering an open microflow, the principles of capillarity are first recalled. The onset of open-channel microflow is next analyzed and the fundamental notion of generalized Cassie angle (the apparent contact angle which accounts for the presence of air) is presented. The theory of the dynamics of open-channel microflows is then developed, using the notion of averaged friction length which accounts for the presence of air along the boundaries of the flow domain. Different channel morphologies are studied and geometrical features such as valves and capillary pumps are examined. An introduction to two-phase open-channel microflows is also presented showing that immiscible plugs can be transported by an open-channel flow. Finally, a selection of interesting applications in the domains of space, materials, medicine and biology is presented, showing the potentialities of open-channel microfluidics.

European Discovery and Exploration of Australia

By: Erwin Feeken

The map of Australia abounds with fascinating geographical place-names, the origins of which have, for long, been hidden in the journals of our early explorers. Now after nine years of research, Erwin Feeken, a highly qualified cartographer, and his wife, Gerda, have finalised the first complete record of Australian geographical place-names and the most comprehensive general reference work on Australian exploration ever published. In European Discovery and Exploration of Australia, there are twenty-three beautifully drawn four-colour maps plus index showing the routes of more than 120 explorers with the locality of their named features numbered to accord with a Key to the Maps. The place-names in the Key have been numbered approximately in chronological order of their naming, though places found during a single expedition have been grouped together. There is also a gazetteer containing over four thousand place-names alphabetically arranged with notes on their origins. The map reference numbers (in brackets) form a cross-reference with the Key to the Maps. The work is introduced by a foreword from Lord Casey and an essay on the nature of Australian exploration by Professor O. H. K. Spate, director of the Research School of Pacific Studies, Australian National University. The text, comprising a survey of Australian exploration, is arranged in the form of biographies of the explorers (describing, for the first time, several almost unknown figures) with emphasis on their expeditions and under the following headings: “The Approach to Australia”; “Exploration before Settlement, 1606–1788”; “From Botany Bay to the Blue Mountains, 1788–1813”; “Land and Sea Expeditions, 1813–1901.” This section of the book is very fully illustrated with 18 full-colour plates and some 150 black-and-white photographs, mostly reproductions of early prints. Concluding the book are bibliographies of sources and references, a list of illustrations, and an index of explorers and ships. The comprehensive nature of this work will ensure that it becomes a valuable reference book for students, while the text and illustrations will appeal to all who are interested in our history. Collectors of Australiana will welcome this most attractive addition to the ever-increasing number of available publications.
