Greener catalysts with iron nanoparticles

A research team at the University of Toronto has announced the discovery of a possible ‘green’ alternative to commonly used catalysts in the food, drug, and fragrance industries. From the March 27, 2012 news item on Nanowerk,

A chemistry team at the University of Toronto has discovered environmentally-friendly iron-based nanoparticle catalysts that work as well as the expensive, toxic, metal-based catalysts that are currently in wide use by the drug, fragrance and food industry.

“It is always important to strive to make industrial syntheses more green, and using iron catalysts is not only much less toxic, but it is also much more cost effective,” said Jessica Sonnenberg, a PhD student and lead author of a paper published this week in the Journal of the American Chemical Society (“Iron Nanoparticles Catalyzing the Asymmetric Transfer Hydrogenation of Ketones”).

The March 27, 2012 University of Toronto news release provides a quote from Sonnenberg which suggests there’s still a lot more work to be done before the toxic metal-based catalysts currently being used could be replaced,

… “Catalysts, even cheap iron ones developed for these types of reaction, still suffer one major downfall,” explained Sonnenberg.  “They require a one-to-one ratio of very expensive organic ligands – the molecule that binds to the central metal atom of a chemical compound – to yield catalytic activity. Our discovery of functional surface nanoparticles opens the door to using much smaller ratios of these expensive compounds relative to the metal centres.  This drastically reduces the overall cost of the transformations.”

This work at the University of Toronto reminded me of another team also working on green catalysts for chemical reactions and also based in Canada, this time at McGill University. The McGill team lead by Chao-Jun Li was mentioned most recently here in a Jan. 10, 2011 posting where their ‘nanomagnetics’ technology to replace the current toxic catalysts  is described.

Interview with Vive Nano’s CTO, Darren Anderson, and CEO Keith Thomas

I first mentioned the Canadian company, Vive Nano, in my Nov. 9, 2009 posting when it received $3.8M from the Ontario government through that province’s Innovation Demonstration Fund. They’ve been mentioned here since (June 25, 2010 posting about their Frost & Sullivan Technology Innovation Award and Oct. 11, 2010 posting about their marketing efforts in India) and, after my good intentions ran out, I finally got a chance to interview Darren Anderson, Vive Nano’s  Chief Technology Officer and (ETA Mar.1.11) Keith Thomas, President and Chief Executive Officer.

(a) Can you tell me a little bit about why the company is called Vive Nano and give me a brief company history, e.g. was it a spin-off from a university; how many founders are there; how did you get to know each other, etc.?

The company was founded by 6 scientists at the University of Toronto.  The scientists had been working together for years and a number had participated in a course called Entrepreneurship 101, which is run by an Ontario-funded organization called MaRS.  [You can find MaRS here.] We decided to pursue a non-traditional route, instead of joining academia or a research lab – and we have not looked back since.  We spun the company out of the university in 2006 and it really got going in 2007 when the full management team joined and outside investment was brought in.

We chose the name Vive Nano because we felt it would work well across cultures.  When we heard the word vive we thought of life; we felt that it had a strong, vibrant and forward thinking feel.   And we felt that it mirrored our company values:  smart, open and responsible.  We strive to be smart in how we execute our work, open to new ideas and responsible in the application of what we do for the greater good.

(b) The Vive Nano website states that your main focus is developing products for the ‘catalyst’ and ‘crop protection’ industries. Could you give me a little more detail about that? For example, I associate crop protection with pesticides, is that what you mean?

A large part of our work is on improved crop protection formulations that can positively impact crop yields and lower environmental impact.  We work with bioinert and biodegradable polymers in place of the solvents currently used to deliver crop protection products.  We are developing products, including pesticides that have the potential to dramatically reduce the amount of chemicals used by farmers, leading to cleaner air, cleaner soil and cleaner water.  We’re enthusiastic about working in crop protection because the safety standards are very stringent and we’re working with partners with tremendous resources and commitment to ensuring product safety.  Vive Nano also works with catalysts, specifically on materials that help to improve the air we breathe and water we drink.

For our efforts, Vive Nano has been recognized as one of Canada’s Top 10 companies, as a leading green technology company by Deloitte, as one of the 2009 Green 15™, and by Canadian Business magazine as the winner of Canada’s Clean15 competition.  In addition, Vive Nano has received other market recognition including:

·       Frost & Sullivan North American Technology of the Year Award – 2010
·       Next 10 Emerging Cleantech Leaders Award Winner – 2009
·       Ontario Premier’s Cleantech Mission to India

(c)  ‘Partnering on projects’ is also mentioned on the website. Could you explain how what you mean by partnering and what kinds of projects and products you have or are currently partnering on?

Vive Nano partners with a range of companies, from small Ontario businesses to Fortune 500 firms.  We develop the products in conjunction with our partners, who provide project goals and market access.  We are not able to talk about most of our projects, but one of our key projects is to reduce the use of solvents in delivering crop protection products so that the products are more environmentally friendly.  We also have smaller projects to develop advanced glass coatings and to clean water.

(d) The website features a description of Vive Nano Product Stewardship where you state: “… prioritization process to ensure product information for products with known toxic effects, physical hazards or potential consumer exposure is provided to our stakeholders in a timely manner.” Could you give some examples of you how provide this information since you sell products such as nano silver, nano cerium oxide, nano zinc oxide, and nano magnetite, all of which, by the way, are subject to a ‘call for information regarding testing procedures’ by the State of California’s Dept. of Toxic Substances Control.

We are members of Responsible Care® and are committed communicating information about our materials to all of our stakeholders, including our employees, our customers, our collaborators and the general public.   We make Product Stewardship Sheets for our materials available, which provide a product description, the chemical identity, uses, and any known health or environmental effects or potential for exposure, as well as risk management information.

We recognize that the state of knowledge relating to health and environmental effects of nanotechnology is in its infancy and as a result we are taking a conservative approach with respect to the design and manufacture of our materials. We continually monitor legislative requirements regarding nanomaterials and aim to exceed all current guidelines with respect to occupational health and waste streams, including water and air emissions.  Much of the concern surrounding exposure to nanomaterials is regarding aerosols, thus we endeavour to work with our materials in liquid form whenever possible.

As I mentioned at the start, we want to be responsible in what we do for the greater good.  We are working with the Canadian National Institute of Nanotechnology in Alberta on a federally funded multi-million dollar project to ensure that all of our products we develop are safe throughout their product lifetime.  We are also participating in a McGill University study to look at product safety.

I’m going to shift focus with these next questions:

(e) Vive Nano was featured in an Oct. 27, 2010 guest column written by Hari Venkatacharya on the subject of Canadian technology firms and the Indian market. Is this involvement part of a larger strategic focus on international markets and/or where there specific reasons for focusing on the Indian market?

Cleantech is global, by nature.  For several years, we have been working internationally, though mostly focused on developed economies.  A few years ago, when developed economies were having issues with the recession, we made a strategic decision to work with a key developing economy and chose India.  There was a sound business case and good demand for our products.  We also were able to successfully work with Hari to access top level decision makers in that market.

(f) What have you learned from your work in the Indian market?

First, focus is important.  India is too vast, so we don’t have an India strategy, but rather a Maharashtra strategy.  Second, cost is important.  India really forced us to drive down our costs – the economics in India are based on volume, not margin.

We also found it important to put things in writing – as prep or follow-up to phone calls, as we had some significant noise issues, especially with poor quality phone lines.  We had a number of times where we would speak to someone on their cellphone in traffic and have difficulty picking out enough words to understand what they meant.

Lastly, we found we needed to be there, in almost constant contact in person.  We found that progress came in waves.  If you were about to go to India, were there, or had just left, there was progress; otherwise other priorities came to our customers’ minds.  We were just one of probably dozens of opportunities from Germany, France, and the US that kept coming to them.  SO we needed to go back.  And back.

(g) What kind of a market (or markets) is there for your products in Canada?

As I mentioned, a lot of our work is on making better crop protection products.  These will support the $150 billion Canadian agriculture industry, which employs one out of every seven Canadians.  We anticipate that they will result in significant environmental and waste reduction benefits.  We are also working on coatings to improve the energy efficiency of glass and improved catalysts can potentially deliver major advances in water and air purification. Canada has an environmentally-aware population and a desire to be a leader in clean technologies, so we think it’s a great place to be.

(h) Are you working on any new products or partnerships that you can discuss at this point?

One thing that we are very excited about is our anti-reflective glass coating.  It can improve light transmission noticeably.  It is a very different application from our crop protection work, but uses the same underlying technology.

(i) Is there anything you’d like to add?

Nothing I can think of.

I would like to add just a bit more about Darren Anderson. From Vive Nano’s Management Team page,

Darren Anderson, Ph.D. was the founding President of Vive Nano. Dr. Anderson currently oversees all technical direction at the company, including product development, strategic direction, and intellectual property. He is the author of 4 issued patents, 24 pending applications, 10 refereed papers, and over 40 conference presentations and publications. He earned his Ph.D. in Chemistry from the University of Toronto as an NSERC Doctoral Fellow.

Plus, I want to say Thank You for taking the time to answer my questions in detail that I much appreciate. I look forward to hearing more about Vive Nano in general, about the new glass coating product, and about the product safety projects with Canada’s National Institute of Nanotechnology and with the researchers at McGill soon.

ETA Feb.28.11: I understand from Darren Anderson that Keith Thomas, Vive Nano’s President and CEO answered some of the questions. So, thank you to Keith Thomas. Here’s his biography from Vive Nano’s Management Team web page,

Keith Thomas is a proven entrepreneur and was most recently CEO of Vector Innovations, which was backed by a number of well regarded venture firms and successfully exited. He has led a number of large-scale projects, restructuring companies in 3 countries at New York-based Tandon Capital, managing strategy and operations projects at Booz Allen & Hamilton and completing corporate finance transactions at Citibank in the US and Europe. He is a member of the Young Presidents Organization (YPO) and holds an M.B.A. from Columbia University, an M.A. in Economics and a B.A.Sc. in Engineering from the University of Toronto.

Tokyo’s nano tech 2010; McGill Nanotech discovery could make chemistry greener; Vancouver Olympics and technology; Off the deep end: an interview with Cheryl Geisler (part 1 of 3)

I’m looking forward to posting (as promised) my piece about the new dean at Simon Fraser University’s Faculty of Communication, Art and Technology. Dr. Cheryl Geisler. First though, I’ll be noting some of the nanotechnology news.

Mentioned here earlier this month in a piece featuring varnish that ‘sings’, Tokyo’s nano tech 2010 International Nanotechnology Exhibition and Conference opens today, Feb. 17 and runs until Feb. 19. I believe this show and conference is one of the oldest and biggest of its type. For those who don’t know, Japan has long been a leader in nanotechnology. In fact, the term was coined by Norio Taniguchi in 1974 in his paper for the Japan Society for Precision Engineering. (Btw, if you’re interested in ‘singing’ varnish, you can read about it here in my posting of Feb. 3, 2010. It is towards the end of the post.)

On a completely other note, there’s a  news item on physorg.com highlighting a new nanotechnology-enabled process, discovered by researchers at McGill University in Montréal, for using catalysts in chemical reactions so they are ‘greener’. From the news item,

A new nanotech catalyst developed by McGill University Chemists Chao-Jun Li, Audrey Moores and their colleagues offers industry an opportunity to reduce the use of expensive and toxic heavy metals. Catalysts are substances used to facilitate and drive chemical reactions. Although chemists have long been aware of the ecological and economic impact of traditional chemical catalysts and do attempt to reuse their materials, it is generally difficult to separate the catalyzing chemicals from the finished product. The team’s discovery does away with this chemical process altogether.

Li neatly describes the new catalyst as “use a magnet and pull them out!” The technology is known as nanomagnetics and involves nanoparticles of a simple iron magnet

Congratulations to the researchers at McGill.

While it’s not nanotech specific it builds on yesterday’s (Feb.16.10) piece about science at the Vancouver Olympics and provides a tidy segue to the Geisler interview.  I’ve found an article about technology and the Vancouver Olympics on Fast Company by Dan Nosowitz. From the article,

The Vancouver Olympics is especially exciting because it combines all of our favorite things: Twitter, Facebook, Google Street View, recycled computer guts, iPhone apps, and mind-controlled light shows. Oh, right, and sports, I guess.

The Medals

Vancouver’s gold, silver, and bronze medals are all constructed partly of metal collected from discarded circuit boards. Teck Resources, a Canadian mining company, supplied the Royal Canadian Mint with recycled gold, silver, and copper (there’s not much bronze in computer parts, apparently) from which these particularly beautiful medals are made. Each medal is laser-etched with a unique design, and the medals are all wavy, meant to simulate the topographic diversity of Vancouver.

I agree, the medals are gorgeous and, in their way, an extraordinary expression of science, technology, and art.  (You can see images of the medals if you click through to the Fast Company article.)

I could wax on longer about how art, science, technology and more are interconnected but I’d rather post the piece I’ve written after interviewing Cheryl Geisler earlier this month. One note before proceeding, I have preserved the flavour of Geisler’s speech as much as possible. This was a stylistic choice as I prefer to ‘hear’ the interview and a standard Q & A style would not have worked well given the volume of contextual information that I wanted to include.

Off the deep end: interview with Cheryl Geisler (part 1 of 3)

The new Dean (since August 2009 when she arrived from Rensselaer Polytechnic Institute in New York State), Dr. Cheryl Geisler, of the new Faculty (since April 2009) of Communication, Art and Technology (FCAT) at Simon Fraser University (SFU) administers three schools

  • Communication,
  • Contemporary Arts and
  • Interactive Arts and Technology

and two components

  • Master of Publishing and
  • under a not yet finalised special arrangement, Masters [sic] of Digital Media

that occupy (or will in Sept.2011 when the School for the Contemporary Arts moves to its new location at Woodward’s in Vancouver’s downtown eastside) five different physical locations in three different Metro Vancouver (Canada) municipalities. (Geisler has managed, as she pledged, to spend time (i.e., roughly a day) at each location if not weekly certainly on a regular basis. This is an impressive achievement when you consider that the Burnaby campus is 20 k from Surrey and 10 k from Vancouver (you can check those distances on this chart). It becomes more impressive when you realize how awkward the routing is if you’re traveling by car or public transit.)

Describing FCAT is a challenge since it hasn’t achieved a stable form (assuming that stability will be possible given the subject areas the faculty represents). Now, imagine trying to get a grasp of the situation when you’ve moved from the east coast of one country to the west coast of a new country, albeit on the same continent. Then add a move from a privately funded postsecondary institution which is an older one, Rensselaer was founded in 1828, to a publicly funded, comparatively new university, SFU was founded in 1965. All of this on top of dealing with a fluid faculty that has a local but wide-flung geography.

“You know, whenever I see something different I always say that I don’t know if this is SFU or the Canadian university system or if it’s Vancouver. I have no way to sort it out,” says Geisler in response to a question about whether or not she’d encountered any surprises after starting her new job. “Some of the reasons that I chose to come here were because of the greater social engagement with the community [that SFU is known for] and a greater emphasis on collegial decision-making processes. In the private university that I came from, we got things done quickly but not always with a lot of input. Now, I’m coming to a system where things don’t get done particularly quickly but there’s always a lot of consultation, so my challenge is to try and marry those two.”

Geisler brings a little more to the job than her past experience as Head of the Department of Language, Literature and Communication at Rensselaer (you can get more details about Geisler’s CV in yesterday’s posting). She was the leader for a project (RAMP Up! Reforming Advancement Processes through University Professions) funded by the US National Science Foundation (NSF). While much of the focus was specifically on women, the overarching project goals can be applied to other situations. From the project website,

Rensselaer Polytechnic Institute’s NSF-funded project for institutional transformation stands for Reforming Advancement Processes through University Professions.  One of the major goals of the RAMP-Up project is institutional reform using mechanisms of professional self-regulation as a means for controlling advancement through faculty ranks.

Unlike reforms aimed at top-down policy initiatives, this type of self-regulatory reform cannot be mandated, but is achieved only by rethinking faculty-to-faculty processes such as networking, mentoring, and peer review. The kind of change necessary for effective institutional reform will come about as a transformation of culture at all levels of the institute, particularly within departments, which are the hubs of faculty work.

Geisler does anticipate bringing some RAMP Up! (so to speak) to SFU. “Yes, [the project] focused on bottom-up cultural transformations of big university/academic processes and I have a big commitment to bottom-up processes which I brought to that project [and had reinforced as I worked on it]. A big emphasis for me now is to create connections between the various components of FCAT and not consider them as separate entities but to try mixing [them] up and see what the synergies could be.”

Similar to a successful RAMP Up! initiative which went through three rounds of funding, Geisler has proposals on her desk to introduce a type of career campaign award to faculty members for working with a mentor and developing a plan for career advancement. “We’ve had a lot of interest from the junior faculty and I believe it’s really one of the first mentoring initiatives at SFU,” says Geisler.

Tomorrow: budget cuts and history.
