Will we cope if the rare earths live up to their name? - tech - 29 October 2010 - New Scientist

Will we cope if the rare earths live up to their name? - tech - 29 October 2010 - New Scientist FOR decades, the world has been busy incorporating the so-called rare earth elements into all manner of high-tech devices, including disc drives, wind turbines and hybrid cars. The messy business of mining the ore and extracting the elements was left to China, and few people in the west cared that the nation controlled 97 per cent of world supply."Rare earth" is an alternative name for the lanthanides - elements 57 to 71 - plus yttrium and scandium, and despite the name most of them were not considered rare at all. The elements hit the headlines a few weeks ago, when China appeared to be blocking exports to Japan and the US. The Chinese government, which has also been tightening its export quotas, claims that it needs to clean up mining procedures and support its own growing demand for rare earths.

Titanium foam builds Wolverine bones - health - 23 September 2010 - New Scientist

Titanium foam builds Wolverine bones - health - 23 September 2010 - New Scientist Bone implants are typically made of solid metal – usually titanium. Though well tolerated by the body, such implants are significantly stiffer than bone.Now Prof.Quadbeck and colleagues have created a titanium implant with a foam-like structure, inspired by the spongy nature of bone. The titanium foam does a better job than solid metal when it comes to matching the mechanical properties of bone, such as flexibility, and this encourages more effective bone regrowth.

They are light, super-strong, and virtually inert inside the body. But whether the implants are destined for your knee, your hip, your spine or your jaw, the silvery metal has one big drawback."Titanium has a mirror surface,” says Tolou Shokufar, a PhD candidate in mechanical engineering–engineering mechanics. Cells don’t adhere to it very well, so implants are often roughened up before they are placed in the body.A good way to roughen titanium is to etch nanotubes into it, since they provide a superb surface for bone cells to grasp onto as part of the healing process."

On the other hand it is perfect to describe a crane as it leaves the ground, rising in a seemingly weightless fashion. This is not just because of the difference in size and weight -- the bird uses its flying surfaces in a completely different manner to the machine. It steers itself by continually varying the geometry of its wings."

Designer nanomaterials on demand: Scientists report universal method for creating nanoscale composites: "Now, researchers at Berkeley Lab's Molecular Foundry, in collaboration with researcher at the University of California, Berkeley, have shown how nanocomposites with desired properties can be designed and fabricated by first assembling nanocrystals and nanorods coated with short organic molecules, called ligands. These ligands are then replaced with clusters of metal chalcogenides, such as copper sulfide. As a result, the clusters link to the nanocrystal or nanorod building blocks and help create a stable nanocomposite. The team has applied this scheme to more than 20 different combinations of materials, including close-packed nanocrystal spheres for thermoelectric materials and vertically aligned nanorods for solar cells."

Ferrous Polycrystalline Shape-Memory Alloy Showing Huge Superelasticity -- Tanaka et al. 327 (5972): 1488 -- Science

Ferrous Polycrystalline Shape-Memory Alloy Showing Huge Superelasticity -- Tanaka et al. 327 (5972): 1488 -- Science: "Shape-memory alloys, such as Ni-Ti and Cu-Zn-Al, show a large reversible strain of more than several percent due to superelasticity. In particular, the Ni-Ti–based alloy, which exhibits some ductility and excellent superelastic strain, is the only superelastic material available for practical applications at present. We herein describe a ferrous polycrystalline, high-strength, shape-memory alloy exhibiting a superelastic strain of more than 13%, with a tensile strength above 1 gigapascal, which is almost twice the maximum superelastic strain obtained in the Ni-Ti alloys. Furthermore, this ferrous alloy has a very large damping capacity and exhibits a large reversible change in magnetization during loading and unloading. This ferrous shape-memory alloy has great potential as a high-damping and sensor material."

India’s Steel Plans through 2015

One of the defining features of the global steel industry is its tendency to build excess capacity. Not so when it comes to the Indian steel industry. As it is well known, China and India both began at the same level when India won Independence. But now, the dragon nation has leapfrogged us and gone so far ahead that comparisons sound ridiculous. In the last 6 years, China added a whopping 300 m tonnes when we added a mere 20 m tonnes. Not that India cannot make up for lost time. After all, we are blessed with abundant raw material, especially in the Eastern part of the country. The problem is delays over land acquisition and mineral rights. More transparency and professionalism could help overcome that.

In fact, there are several 10 to 12 m tonnes capacity Greenfield ventures lined up. Investors have rushed in to sign as many as 222 memoranda of understanding for building 276 m tonnes of new steel capacity. Not that all of them are willing or able. But the serious players have hung around despite the recent financial crisis. ArcelorMittal and Posco are still keen on India. And so are Tata Steel, JSW, JSPL and Essar. Little wonder then that the steel minister believes that India can become the second largest steel producer in the world by 2015, next only to China. But it is high time the government started helping these players and stopped dragging its feet.
