NANOTECHNOLOGY 6 Blurring the lines between nanotech and biochemistry Korean Scientists at the Center for Nanoparticle Research, IBS have come up with a ‘fabric’ made of ~150 nm dia silver nanow- ires in an interlocking coil, and embedded in elastic material. This conductive fabric can be linked to a small battery and provides direct heating over and around the joint. Because it is light-weight, wearable, and breathable, it can be worn while running around. by Gavin Chait

MINERALS PROCESSING AND METALLURGY 26 What challenges are faced when performing EPCM and EPC projects in Africa? Africa is a relatively untouched continent when it comes to mineral resources. Many large mining houses are showing a bigger interest in Africa than before and South African project companies are also showing a greater interest in African projects. by Trevor Arlington – Project Manager at Fluor South Africa (Pty) Limited

PETROCHEMICALS 10 Optimising quill and injector performance in refinery operations
and the Southern African Association of Energy Efficiency
There are dozens of operations in refineries where quills and injectors are used. Before we discuss usage and performance optimisation, let’s clarify the difference between a quill and an injector. The terms are often used interchangeably even though the devices are quite different. by Dan Vidusek and Chuck Munro, both of Spraying Systems Co, Wheaton, Illinois, USA
