In constant use since ancient times, glass remains a highly valued material that is ubiquitous in daily life. Today, glass has become an indispensable and essential component in such fields as photonics, optical communications, photovoltaic cells, household appliances, vehicles, and building materials. However, one of major stumbling blocks for its optimal use is the low glass-forming ability (GFA) of many glass-forming compositions, which is far from being adequately solved. Understanding the nature of the GFAs of materials is the key to the development of new glasses with improved properties and manufacturability for various engineering applications. The rapid development of new glasses over the past several decades has led to increasingly complex material compositions. However, the phase diagrams of these materials have yet to be properly addressed even though such diagrams are extremely useful in rationally designing glass-forming compositions and predicting their behavior in pursuit of new functional glasses with particular desired properties. In this context, the present review strives to provide new insights into the formation of glasses and glass-forming regions through quantitative calculations and predictions based on a comprehensive survey and analysis of the existing experimental observations and theoretical considerations, a considerable portion of which stems from work performed in our own laboratory.

“…Thus, intense 2.7 μm emission can only be obtained in host with low phonon energy such as fluoride, chalcogenide, fluorophosphate and germinate glasses. [4][5][6][7] Among them, tellurite glass has attracted a great deal of interest not only for its relatively lower maximum phonon energy (about 700 cm −1 ), but also for the improvement in chemical and mechanical stability as well as the high refractive index, excellent infrared transmissivity. 8 On the other hand, the residual hydroxyl groups (OH − ) in glass could be the quenching center for 2.7 μm emission as the vibrational energy of OH − is comparable to the energy difference between 4 I 11/2 and 4 I 13/2 level.…”

Natural discharge after pulse and cooperative electrodes to enhance droplet velocity in digital microfluidics

et al. 2014

View full text Add to dashboard Cite

Digital Microfluidics (DMF) is a promising technology for biological/chemical micro-reactions due to its distinct droplet manageability via electronic automation, but the limited velocity of droplet transportation has hindered DMF from utilization in high throughput applications. In this paper, by adaptively fitting the actuation voltages to the dynamic motions of droplet movement under real-time feedback monitoring, two control-engaged electrode-driving techniques: Natural Discharge after Pulse (NDAP) and Cooperative Electrodes (CE) are proposed. They together lead to, for the first time, enhanced droplet velocity with lower root mean square voltage value.
