Nanotechnology-enhanced roads in South Africa and in Kerala, India

It’s all about road infrastructure in these two news bits.

Road building and maintenance in sub-Saharan Africa

A July 7, 2016 news item on mybroadband.co.za describes hopes that nanotechnology-enabled products will make roads easier to build and maintain,

The solution for affordable road infrastructure development could lie in the use of nanotechnology, according to a paper presented at the 35th annual Southern African Transport Conference in Pretoria.

The cost of upgrading, maintaining and rehabilitating road infrastructure with limited funds makes it impossible for sub-Saharan Africa to become competitive in the world market, according to Professor Gerrit Jordaan of the University of Pretoria, a speaker at the conference.

The affordability of road infrastructure depends on the materials used, the environment in which the road will be built and the traffic that will be using the road, explained Professor James Maina of the department of civil engineering at the University of Pretoria.

Hauling materials to a construction site contributes hugely to costs, which planners try to minimise by getting materials closer to the site. But if there aren’t good quality materials near the site, another option is to modify poor quality materials for construction purposes. This is where nanotechnology comes in, he explained.

For example, if the material is clay soil, it has a high affinity to water so when it absorbs water it expands, and when it dries out it contracts. Nanotechnology can make the soil water repellent. “Essentially, nanotechnology changes the properties to work for the construction process,” he said.

These nanotechnology-based products have been used successfully in many parts of the world, including India, the USA and in the West African region.

There have also been concerns about road building and maintenance in Kerala, India.

Nanotechnology for city roads in Kochi

A March 23, 2015 news item in the Times of India describes an upcoming test of a nanotechnology-enabled all weather road,

Citizens can now look forward to better roads with the local self-government department planning to use nanotechnology to construct all-weather roads.

For the district trial run, the department has selected a 300-metre stretch of a panchayat road in Edakkattuvayal panchayat. The trial would experiment with nanotechnology to build moisture resistant, long-lasting and maintenance-free roads.

“Like the public, the department is also fed up with the poor condition of roads in the state. Crores of rupees are spent every year for repairing and resurfacing the roads. This is because of heavy rains in the state that weakens the soil base of roads, resulting in potholes that affect the ride-quality of the road surface,” said KT Sajan, assistant executive engineer, LSGD, who is supervising the work.

The nanotechnology has been developed by Zydex Technologies, a Gujarat-headquartered firm. The company’s technology has already been used by major private contract firms that build national highways in India and in other major projects in European and African countries.

Oddly, you can’t find out more about the Zydex products mentioned in the article on its Roads Solution webpage , where you are provided a general description of the technology,

Revolutionary nanotechnology for building moisture resistant, long lasting & maintenance free roads through innovative adaptation of Organosilane chemistry.

Zydex Nanotechnology: A Game Changer

Zydex Nanotechnology has a value propositions for all layers of the road

SOIL LAYERS
Zydex Nanotechnology makes the soil moisture resistant, reduces expansiveness and stabilizes the soil to improve its bearing strength manifold. If used with 1% cement, it can stabilize almost any type of soil, by improving the California Bearing Ratio (CBR) to even 100 or above.

Here is the real change in game, as stronger soil bases would now allow optimization of road section thicknesses, potentially saving 10-15% road construction cost.

BOND COATS
Prime & Tack coats become 100 % waterproofed, due to penetration and chemical bonding. This also ensures uniform load transfer. And all this at lower residual bitumen.

ASPHALTIC LAYERS
Chemical bonding between aggregates and asphalt eliminates moisture induced damage of asphaltic layers.

Final comment

I hadn’t meant to wait so long to publish the bit about Kerala’s road but serendipity has allowed me to link it to a piece about South Africa ‘s roads and to note a resemblance to the problems encountered in both regions.

Alberta’s Ingenuity Lab opens new facility in India and competes in the Carbon XPRIZE

India

The Ingenuity Lab in Alberta has made two recent announcements. The first one to catch my attention was a May 7, 2016 news item on Nanotechnology Now,

Ingenuity Lab is proud to announce the opening of the Ingenuity Lab Research Hub at Mahatma Gandhi University in Kottayam, Kerala India, to implement applied research and enable the translation of new 22nd century technologies. This new facility is the result of collaboration between the International and Inter University Centre for Nanoscience Nanotechnology (IIUCNN) and Ingenuity Lab to leverage what each participant does best.

Should the Nanotechnology Now news item not be available you can find the same information in a May 6, 2016 news item in The Canadian Business News Journal. Here’s the rest of the news item,

Ingenuity Lab, led by Dr. Carlo Montemagno, brings the best minds together to address global challenges and was in 2014 voted the Best Nanotechnology Research Organisation in 2014 by The New Economy. IIUCNN is led by Professor Sabu Thomas, whose vision it is to perform and coordinate academic and research activities in the frontier areas of Nanoscience and Nanotechnology by incorporating physical, chemical, biological and environmental aspects.

The two institutions are world-renowned for their work, and the new partnership should cover areas as diverse as catalysis, macromolecules, environmental chemistry, biological processes and health and wellness.

“The initial focus,” according to Ingenuity Lab’s Director Dr. Carlo Montemagno, “Will be on inexpensive point of care healthcare technologies and water availability for both agriculture and personal consumption.” However, in the future, he says, “We plan to expand the scope to include food safety and energy systems.”

Ingenuity Lab’s role is to focus on producing, adapting and supplying new materials to Ingenuity Lab India to focus on final device development and field-testing. The India team members know what system characteristics work best in developing economies, and will establish the figures of merit to make an appropriate solution. Alberta team members will then use this information to exercise its skills in advance materials and systems design to be crafted into its final form and field-tested.

The collaboration is somewhat unique in that it includes the bilateral exchange of students and researchers to facilitate the commercial translation of new and game changing technologies.

Dr. Babu Sebastian, Honourable Vice Chancellor of Mahatma Gandhi University, will declare the opening of the new facility in the presence of Dr. Montemagno, who will explain the vision of this research hub in association with his plenary lecture of ICM 2016.

Carbon XPRIZE

A May 9, 2016 press release on Market Wired describes Ingenuity Lab’s latest venture into carbon ‘transformation’,

Alberta-based Ingenuity Lab has entered the Carbon XPRIZE under the name of Ingenuity Carbon Solutions. With competition registration taking place in March, Ingenuity Carbon Solutions plans to launch its latest carbon transformation technology and win the backing it so deserves on the world stage.

Ingenuity Lab is working to develop a technology that transforms CO2 emissions and changes the conversation on carbon and its consequences for the environment. By developing nano particles that have the capability to sequester CO2 from facility gas flue emissions, the technology can metabolize emissions into marketable by-products.

The Carbon XPRIZE this year seeks to inspire solutions to the issue of climate change by incentivizing the development of new and emerging CO2 conversation technologies. Described recently in a WEF [World Economic Forum] survey as the biggest potential threat to the economy in 2016, climate change has been targeted as a priority issue, and the XPRIZE has done a great deal to provide answers to the climate question.

Renowned for its role in bringing new and radical thought leaders into the public domain, the XPRIZE Board of Trustees include Elon Musk, James Cameron and Arianna Huffington and the prize never fails to attract the world’s brightest minds.

This year’s Carbon XPRIZE challenges participants including Ingenuity Lab and its Ingenuity Carbon Solutions team to reimagine the climate question by accelerating the development of technologies to convert CO2 into valuable products. Ingenuity Carbon Solutions and others will compete in a three-round competition for a total prize purse of $20m, with the winnings going towards the technology’s continued development.

I hope to hear more good news soon. Alberta could certainly do with some of that as it copes with Fort McMurray’s monstrous wildfire (more here in a NASA/ Goddard Space Flight Center May 9, 2016 news release on EurekAlert).
