Nanoporous Silicon as a Green, High-Tech Educational Tool

A green supplier selection model for high-tech industry

With growingworldwide awareness of environmental protection, green production has become an important issue for almost every manufacturer and will determine the sustainability of a manufacturer in the long term. A performance evaluation system for green suppliers thus is necessary to determine the suitability of suppliers to cooperate with the firm. While the works on the evaluation and/or sele...

Silicon Solar Cells with Nanoporous Silicon Layer

Virtual High Tech Clusters - The Modern Silicon Valley?

Silicon Valley – often imitated, but never succeeded. High tech clusters have been for years and still are the attraction for many companies and investors to settle down in one of those lucrative regions in order to get a big share of the profit that is gained there. The economic conditions, that new start-ups find there, are apparently so favourable that economic success is inevitable. Now, a ...

Robotics as an Educational Tool

This paper explores a new educational application of Piaget’s theories of cognitive development i.e. the use, as a teaching tool, of physical robots conceived as artificial organisms. By using simple assembly kits, students at all levels are able to project and construct real robots that simulate the behaviors of animals. The process of constructing real robots helps students to understand conc...

Nanoporous silicon networks as anodes for lithium ion batteries.

Nanoporous silicon (Si) networks with controllable porosity and thickness are fabricated by a simple and scalable electrochemical process, and then released from Si wafers and transferred to flexible and conductive substrates. These nanoporous Si networks serve as high performance Li-ion battery electrodes, with an initial discharge capacity of 2570 mA h g(-1), above 1000 mA h g(-1) after 200 c...
