Ceramic,Polymer Ba0.6Sr0.4TiO3/Poly(Methyl Methacrylate) Composites with Different Type Composite Structures for Electronic Technology

INTERNATIONAL JOURNAL OF APPLIED CERAMIC TECHNOLOGY, Issue 4 2010
Hong Wang
Ba0.6Sr0.4TiO3 (BST)/poly(methyl methacrylate) (PMMA) composites with 0,3, 1,3, and 2,2 type structures were prepared and studied. The effect of composite type on the dielectric properties of BST/PMMA composites was comprehensively investigated by both theoretical and experimental methods. The 1,3 type composite shows the highest permittivity and dielectric tunability, while the 2,2 and 0,3 type composites show lower permittivity as well as lower dielectric tunabilities. The experimentally measured dielectric properties are in agreement with the theoretically calculated values. The results help in understanding and tailoring the dielectric properties of ceramic,polymer composites by choosing a suitable composite structure. [source]

The Impact of Virtual Embeddedness on New Venture Survival: Overcoming the Liabilities of Newness1

ENTREPRENEURSHIP THEORY AND PRACTICE, Issue 2 2007
Eric A. Morse
In this article, we examine the impact of virtual embeddedness,the establishment of interorganizational connections through the use of electronic technologies,on the likelihood of new venture survival. We explore the effects of recent technological and social changes on traditional conceptions of the liabilities of newness. We argue that virtual embeddedness positively affects new venture survival by decreasing the liabilities of newness associated with a new venture's need to create and manage new roles and systems, lack of extant trust relationships, lack of social capital, and lack of economic capital. This argument has important implications for both the study and management of contemporary new ventures. [source]

Reactions to surveillance, capable technology
This article offers a critique of recent characterisations of the effects of electronic technologies in the workplace. It presents detailed case study evidence that calls into question a number of common theoretical assumptions about the character of surveillance at work and the responses of employees to it.

Ultrasonic-activated micellar drug delivery for cancer treatment

JOURNAL OF PHARMACEUTICAL SCIENCES, Issue 3 2009
Ghaleb A. Husseini
Abstract The use of nanoparticles and ultrasound in medicine continues to evolve. Great strides have been made in the areas of producing micelles, nanoemulsions, and solid nanoparticles that can be used in drug delivery. An effective nanocarrier allows for the delivery of a high concentration of potent medications to targeted tissue while minimizing the side effect of the agent to the rest of the body. Polymeric micelles have been shown to encapsulate therapeutic agents and maintain their structural integrity at lower concentrations. Ultrasound is currently being used in drug delivery as well as diagnostics, and has many advantages that elevate its importance in drug delivery. The technique is noninvasive, thus no surgery is needed; the ultrasonic waves can be easily controlled by advanced electronic technology so that they can be focused on the desired target volume. Additionally, the physics of ultrasound are widely used and well understood; thus ultrasonic application can be tailored towards a particular drug delivery system. In this article, we review the recent progress made in research that utilizes both polymeric micelles and ultrasonic power in drug delivery. © 2008 Wiley-Liss, Inc. and the American Pharmacists Association J Pharm Sci 98:795,811, 2009 [source]

Stretchable, Curvilinear Electronics Based on Inorganic Materials

ADVANCED MATERIALS, Issue 19 2010
Dae-Hyeong Kim
Abstract All commercial forms of electronic/optoelectronic technologies use planar, rigid substrates. Device possibilities that exploit bio-inspired designs or require intimate integration with the human body demand curvilinear shapes and/or elastic responses to large strain deformations. This article reviews progress in research designed to accomplish these outcomes with established, high-performance inorganic electronic materials and modest modifications to conventional, planar processing techniques. We outline the most well developed strategies and illustrate their use in demonstrator devices that exploit unique combinations of shape, mechanical properties and electronic performance. We conclude with an outlook on the challenges and opportunities for this emerging area of materials science and engineering. [source]
