Smart Materials for Green(er) Cities
The transition to sustainable or green(er) cities requires the development and implementation of many innovative technologies. It is vital to ensure that these technologies are themselves as sustainable and green as possible. In this context, smart materials offer excellent prospects for application. They are capable of performing a number of tasks (e.g., repair, opening/closing, temperature measurement, storage and release of thermal energy) without embedded electronics or power supplies.

Prepay Mobile Phone
A prepay mobile device (also commonly referred to as pay-as-you-go (PAYG), pay-as-you-talk, pay and go, go-phone or prepaid) is a mobile device such as a phone for which credit is purchased in advance of service use. The purchased credit is used to pay for telecommunications services at the point the service is accessed or consumed. If there is no credit, then access is denied by the mobile network. Users can top up their credit at any time using a variety of payment mechanisms. The alternative billing method (and what is commonly referred to as a mobile contract) is the postpaid mobile phone, where a user enters into a long-term (lasting 12, 18 or 24 months) or short-term (also commonly referred to as a rolling contract or a 30-day contract) billing arrangement with a mobile network operator or carriage service provider (CSP). "Pay-as-you-go", "PAYG", and similar terms are also used for other non-telecommunications services paid for in the same way.
