Indian defence to use nanotechnology, ties up with startup Log 9

Log 9 Materials is essentially looking at various ways of using graphene — a form of carbon that is also called ‘wonder material’

Nanotechnology, a nascent but one of the fastest growing areas of science and industry, will soon see its first commercial application for Indian defence forces.

Bengaluru-based Log 9 Materials will collaborate with the defence to help it build various products and applications while conserving energy, said Akshay Singhal, founder of the nanotechnology startup.

Nanotechnology involves production and manipulation of matter on a tiny scale, with at least one dimension sized between 1-100 nanometres, or one billionths of a metre. The field has boundless potential in sectors ranging from health and medicine to defence and textiles.

Log 9 Materials is essentially looking at various ways of using graphene — a form of carbon that is also called ‘wonder material’ because it’s the lightest, strongest, thinnest, best heat- and electricity- conducting material discovered yet, just one atom thick — for filtering and energy conservation.

The company has already built lead acid batteries with high efficiency by incorporating graphene.

Akshay Singhal, founder of Log 9 Materials“When we use graphene, the productivity naturally gets better and as it renders higher capacity without draining the battery,” said Singhal, an IIT Roorkee alumnus who founded Log 9 in 2015. “These batteries’ life is increased by 1.3x time when we use graphene in it,” he added.

Log 9 has started manufacturing these batteries at a commercial scale and will help the defence in building various applications while conserving energy.

The company has also tied up with Engineers India Ltd (EIL), a state-owned firm that provides technical services to petroleum refineries and other industrial projects, to help in refining oil.


Under this collaboration, Log 9 is building a membrane to separate oil from water by repelling oil and retaining water, Singhal, 23, told ET.

“Graphene’s filtration works differently as it absorbs unwanted particles once the substance is passed through it,” he said. “The processes for purification are different — for instance, air is different from oil — but the fundamentals remain the same, which is absorption.”

In 2016, Log 9 launched a cigarette filter through a tie-up with a pharmaceutical company.

The firm, which has a research and development centre in Bengaluru, has also collaborated with the Indian Institute of Sciences (IISc) to develop products jointly by using the latter’s analytical and research capabilities.

While nanotechnology has huge potential to impact everyday life, it has yet to attract Indian talent and entrepreneurs in a big way.

The country has just about 50 active nanotech startups and out of them only five have been funded so far, according to startup data platform Tracxn. The total funding Indian nanotech startups have raised is estimated at around $0.3 million, or about Rs 1.93 crore.

Log 9 Materials, which had raised an undisclosed amount of funding in pre-Series A, is now in talks to raise its next round of funding.

In India, the Government has invested over Rs 1000 crore funding in 2007 for five years through the Department of Science and Technology (DST) and Nano Science and Technology Initiative (NSTI) to provide research and infrastructure. However, the progress made has not been significant.

Meet Log 9 Materials that is in the business of purification
It is working on a suite of products in areas of air purification, non-electric water purification, efficient energy storage and display and hopes to get them ready by the end of the year.Supraja Srinivasan | ET Bureau | June 02, 2017, 08:51 IST

What if we told you that a simple filter could help reduce the toxins that your cigarette emits by half and still not spoil the user experience for you?

That's right. A bunch of students from IIT Rourkee are the brainwave behind Log 9 Materials -a startup that attempts to create scientifically proven nanotechnologies into commercial products or technologies that can be licensed out to corporates. PPuF, short for the Post Purification Filter, is their first such product.

PPuF is a plug-on filter for cigarettes that removes toxins from smoke without compromising the flavour of the cigarette. It incorporates nanocomposite filter particles encased in a bio-safe plastic casing which chemically binds cancer causing toxic chemicals.

But PPuF is just the start of the journey for the 23-year-old Akshay Singhal, founder of Log 9 Materials, who is currently pursuing his PhD in Nanotechnology from IIT Rourkee. The company was incubated at the TIDES Incubation Centre of the institution two years ago. PPuF was a joint effort with Singhal's father Vivek Kumar and his junior Kartik Hajela, VP Business Development, who graduated from the college just this year. “We work primarily with a material called graphene which has been discovered recently and is very adaptable across applications and products with different end uses,“ said Singhal.

Log 9 Materials is working on a suite of products in areas of air purification, non-electric water purification, efficient energy storage and display and hopes to get them ready by the end of the year.Singhal said the idea is to incorporate graphene in a lead battery to enhance efficiency when it comes to conserving energy. The company has a research and development centre in Bengaluru and has collaborated with the Bengalurubased Indian Institute of Sciences (IISc) to develop products jointly by using the latter's analytical and research capabilities. All new products will be made at the company's manufacturing facility in Uttar Pradesh.

Initially bootstrapped by Singhal and his family with about Rs 40 lakhs, IIT Rourkee invested about Rs 20 lakhs in the company in its early days to help develop PPuF. Log 9 Materials recently raised its first institutional funding from Delhi-based micro-venture capital firm, GEMs. Having sold 45,000 pieces of PPuF so far, the company is also in early talks with cigarette manufacturers such as ITC and Godfrey Phillips to incorporate the graphene tech-based filter during the process of cigarette production.“The response has been positive so far and they have shown interest in testing this,“ said Singhal.

Recently somebody found out a way to create a bulleproof t-shirt using graphene. Dont know the backround to it but the catch was that two layers of graphene formed diamond like matter during impact. That material is really amazing :)

Scientists Discover Process for Transitioning Two-Layer Graphene into a Diamond-Hard Material on Impact

The innovation could enable development of a range of flexible, impenetrable materials capable of protecting the body and fragile objects

NEW YORK, (Dec. 18, 2017) — Imagine a material as flexible and lightweight as foil that becomes stiff and hard enough to stop a bullet on impact. In a newly published paper in Nature Nanotechnology, researchers across The City University of New York (CUNY) describe a process for creating diamene: flexible, layered sheets of graphene that temporarily become harder than diamond and impenetrable upon impact.

Scientists at the Advanced Science Research Center (ASRC) at the Graduate Center, CUNY, worked to theorize and test how two layers of graphene — each one-atom thick — could be made to transform into a diamond-like material upon impact at room temperature. The team also found the moment of conversion resulted in a sudden reduction of electric current, suggesting diamene could have interesting electronic and spintronic properties. The new findings will likely have applications in developing wear-resistant protective coatings and ultra-light bullet-proof films.

“This is the thinnest film with the stiffness and hardness of diamond ever created,” said Elisa Riedo, professor of physics at the ASRC and the project’s lead researcher. “Previously, when we tested graphite or a single atomic layer of graphene, we would apply pressure and feel a very soft film. But when the graphite film was exactly two-layers thick, all of a sudden we realized that the material under pressure was becoming extremely hard and as stiff, or stiffer, than bulk diamond.”

Angelo Bongiorno, associate professor of chemistry at CUNY College of Staten Island and part of the research team, developed the theory for creating diamene. He and his colleagues used atomistic computer simulations to model potential outcomes when pressurizing two honeycomb layers of graphene aligned in different configurations. Riedo and other team members then used an atomic force microscope to apply localized pressure to two-layer graphene on silicon carbide substrates and found perfect agreement with the calculations. Experiments and theory both show that this graphite-diamond transition does not occur for more than two layers or for a single graphene layer.

“Graphite and diamonds are both made entirely of carbon, but the atoms are arranged differently in each material, giving them distinct properties such as hardness, flexibility and electrical conduction,” Bongiorno said. “Our new technique allows us to manipulate graphite so that it can take on the beneficial properties of a diamond under specific conditions.”

The research team’s successful work opens up possibilities for investigating graphite-to-diamond phase transition in two-dimensional materials, according to the paper. Future research could explore methods for stabilizing the transition and allow for further applications for the resulting materials.

This work was funded by the BES Office of the Department of Energy and the complete list of authors includes Yang Gao, Tengfei Cao, Filippo Cellini, Claire Berger, Walt Heer, Erio Tosatti, Angelo Bongiorno and Elisa Riedo.


Apparently, the materiel won't be stiff on impact with more than 2 atomic layer of Graphene. Making the materiel in laboratory condition is one thing, manufacturing such a thin material in industrial scale is another story. I don't think they managed to build a product like bullet proof T-shirt yet.
