Latest offering from SRI boasting 100% Butyl Free SRI DVR Compound
Then when the same DVR Compound is added to Volume Medium grade Asian Retread Compound the results are interesting to say the least!The retention of properties is very exciting especially the EB% !!
With the significance of high Rolling Resistance and Heat Build Up in tyres being a direct measure of CO2 generation contributing to Global Warming its a particularly important factor in terms of sustainability in Commercial Vehicle and Passenger Car Tyres. The SRI DVR Compound is the first recycled content tested by global tyre manufacturers that does not impact adversely on Rebound Hysteresis test results which is a benchmark for Rolling Resistance and Heat Buildup in their tread compounds.
Graphene transcends disciplines
Interestingly, a few days ago The Economist published an article stating that “Bacteria may be the key to turning graphene into a semiconductor”, showing the potential of graphene in transcending disciplines in an effort to deliver superior products and services that are better for the ‘People, Profit and Planet’.
Given graphene’s extraordinary electrical conductivity properties, the possibility of making thin, flexible, semi-transparent graphene based electronics has existed in the public imagination for some time now. However, to date tests on graphene sheets showed that the electric current moves randomly and in all directions. Moreover, graphene does not have a bandgap – “a property needed to create the distinct “on” and “off” electronic states that transistors rely on to work, and which is induced in a material by disrupting the way its electrons are distributed”.
Tesla has open-sourced its patents on electric vehicle technology, according to a post on the company’s blog by CEO Elon Musk.
Musk explains that one of the company’s biggest goals is to move the entire electric vehicle market forward, which it can’t accomplish if it’s making it harder for others to enter the space:
Tesla Motors was created to accelerate the advent of sustainable transport. If we clear a path to the creation of compelling electric vehicles, but then lay intellectual property landmines behind us to inhibit others, we are acting in a manner contrary to that goal. Tesla will not initiate patent lawsuits against anyone who, in good faith, wants to use our technology.
I love my three young children immensely. So it’s hard for me to be fully rational about them. Of course they are the smartest, the best looking, and the most athletic. I’m not alone — all parents are irrational. We lose sleep worrying about things we can’t control and take pride in ridiculously small achievements we had nothing to do with.

Joel Makower: Green business maven shares his insights
Makower, one of the most respected voices in green business, talks about greener corporations, what the government could be doing to foster more environmentally friendly businesses, and why he’s optimistic about the future.Mon, Jan 30 2012 at 10:16 PM EST Photo: Joel Makower Joel Makower grew up in California and graduated from UC Berkeley with a degree in journalism. He worked as a journalist and nationally syndicated columnist and is a prolific author, with more than a dozen books published, including the oral history of the Woodstock music festival, a book that Rolling Stone called “the definitive history of the mega-event.” He has focused on the environment for more than 20 years and is a well-respected speaker, writer and consultant on all things green business including regular appearances on NPR’s “Marketplace” as a commentator. Joel is the chairman and executive editor of the GreenBiz Group and founder of GreenBiz. I have been a fan of Joel’s writing for as long as I’ve been reading environmental news and commentary. His book “Beyond The Bottom Line” was one of the first green business books I read and was a major influence in how I see the intersection between business and environment. I’m thrilled that he so kindly took the time to answer these seven questions. MNN: Does the world need saving?

Metal-on metal hip replacements are lubricated by a layer of graphite, say scientists in the US. And this graphitic layer may be the product of proteins ground up the implant itself. This knowledge could help the design of new implants but also raises important questions about the action of the graphite in the body.
Over 50,000 hip replacements are performed each year in the UK and in the US that number is over 200,000. But although surgeons are moving towards low wearing metal-on-metal joints, no one is precisely sure why the two metal pieces slide so well. Although it is known there is a layer that affects the friction, lubrication and wear of the two surfaces, known as a tribological layer, until now no-one has examined its composition.

Tesla today announced official pricing for its four-door electric sedan: $49,900 for a base Model S after a $7,500 federal tax credit.
The announcement comes after months of Tesla founder Elon Musk promising to deliver his first four-door electric car for around $50,000. (Tesla started selling its battery-powered $109,000 Roadsters in 2008.)
Of course, higher performing versions of the seven-passenger sedan will cost more: $59,900 for a 60 kWh (230-mile-range) model and $69,900 for an 85 kWh (300-mile-range) model. The 85 kWh performance Model S, which comes with additional equipment like Nappa leather interior and performance wheels, will cost $79,900 after federal tax rebates. Musk says it will go 0-60mph in 4.4 seconds. More…….

China has a severe shortage of skilled talent and, in a policy reversal, has decided to open its doors to talent from around the world. This could mean that the brilliant NASA scientists the U.S. laid off, could find new employment — and a new home — in Shanghai or Beijing.
Chinese research labs have long had difficulty recruiting qualified workers to perform necessary research and development, and its corporations struggle to find competent managers. The situation will likely get worse as China’s high-tech industries grow and it increases its national R&D spending from the present 1.62 percent of GDP, according to the Chinese government, to the planned 2.5 percent by 2020. China’s President Hu Jintao, in May 2010, declared talent development a national priority in order to fill the void. The goal is to dramatically increase the education level of China’s workforce and to build an innovation economy.
