A possible solution to global warming

1 Oct 2006
It was Jean Fourier who, in 1827, first realised that it was the atmosphere that protects us from the coldness of space. In the 1850s, John Tyndall recognised that only...

Firing on all cylinders - microwave-assisted firing of ceramics

1 Oct 2006
A model for estimating the potential for energy and associated cost savings has been developed based on current information and audited test results. Model results show that microwave-assisted gas firing for the clay industry provides favourable payback periods based on energy cost reductions, in addition to environmental benefits.

House of the rising sun - the effects of thermal mass on housing

1 Oct 2006
Investigations into lightweight and heavyweight constructions in relation to potentially increasing temperatures due to climate change show that lightweight construction leads to increased internal temperatures and greater levels of discomfort. The case for high thermal mass buildings in saving energy is not confirmed, but careful consideration should be given to insulation, ventilation and solar gain.

Boning up on selection ― Regenerative glass scaffolds for tissue replacement

1 Oct 2006
Selecting materials for en vivo use has moved away from tissue replacement implants to using materials that stimulate the body's own regenerative mechanisms. The two main strategies are in situ tissue regeneration and tissue engineering, both techniques grow cells on bone scaffolds which are directly implanted into the body.

Building bridges - Duplex steel alloys used in bridge construction

1 Oct 2006
The perception in civil engineering that the use of stainless steels for bridge construction is expensive is changing. In times of high alloy prices duplex steels have become more economically attractive. These newer lean alloys can provide corrosion protection over a wide range of environmental conditions typical of bridge structures.
