Sustainable Nano on Open Access Sustainably

(This article is a cross-post between EveryWhereChemistry and Sustainable-Nano!)

Sustainability’s future is now. Our recent article was just published in an all-electronic journal, ACS Central Science, which is among the first of the American Chemical Society (ACS) journals offered without a print option. It therefore embodies sustainability as it requires no paper resources, thereby limiting the journal’s carbon footprint to only what is required for maintaining the information electronically in perpetuity. It is also completely Open Access, which means our article is available for all to read. Does this equal accessibility (called “flat” because there is no hierarchy in levels of access) amount to yet another layer of sustainability? More on that question in a moment. Meanwhile as the article itself is about sustainability, it embodies the repetitive word play in the title of this post.

But there is another double meaning in the publishing of this work: The flatness underlying the vision of Open Access is also at play in how the work was done. ELEVEN different research groups were involved in formulating the ideas and writing the paper. This lot provided tremendous breadth of expertise, but the flatness in the organizational effort allowed us to merge it all together. Of course, it wouldn’t have happened without significant leadership, and Cathy Murphy, the paper’s first author, orchestrated us all magnificently. While flatness in organizational behavior isn’t typically considered part of sustainability, in this case it provided for the efficient utilization of resources (that is, ideas) across a broader cohort.

So what is our article about? Fifteen years into the 21st century, it is becoming increasingly clear that we need to develop new materials to solve the grand challenges that confront us in the areas of health, energy, and the environment. Nanoparticles are playing a significant role in new material development because they can provide human-scale effects with relatively small amounts of materials. The danger is that because of their special properties, the use of nanoparticles may have unintended consequences. Thus, many in the scientific community, including those of us involved in writing this article, are concerned with identifying rules for the design and fabrication of nanoparticles that will limit such negative effects, and hence make the particles sustainable by design. In our article, we propose that the solution of this grand challenge hinges on four critical needs:

1. Chemically Driven Understanding of the Molecular Nature of Engineered Nanoparticles in Complex, Realistic Environments
2. Real-Time Measurements of Nanomaterial Interaction with Living Cells and Organisms That Provide Chemical Information at Nanometer Length Scales To Yield Invaluable Mechanistic Insight and Improve Predictive Understanding of the Nano−Bio Interface.
3. Delineation of Molecular Modes of Action for Nanomaterial Effects on Living Systems as Functions of Nanomaterial Properties
4. Computation and Simulation of the Nano−Bio Interface.

In more accessible terms, this translates to: (1) It’s not enough to know how the nanoparticles behave in a test tube under clean conditions as we need to know how they might behave at the molecular scale in different solutions. (2) We also need to better understand and measure the effects of nanoparticles at contact points between inorganic materials and biological matter. (3) Not only do we need to observe how nanoparticles behave in relation to living systems, but to understand what drives that behavior at a molecular level. (4) In order to accelerate design and discovery as well as to avoid the use of materials whenever possible, we also need to design validated computational models for all of these processes.

Take a look at the article for the details as we collectively offer a blueprint for what research problems need to be solved in the short term (a decade or so), and how our team of nanoscientists, with broad experience in making, measuring, and simulating nanoparticles in complex environments, can make a difference.

The title of the article is "Biological Responses to Engineered Nanomaterials: Needs for the Next Decade.” The work was funded by the NSF as part of the Phase I Center for Sustainable Nanotechnology (CSN, CHE-124051). It was just released at ACS Central Science, XXXX (2015) as an ASAP Article. The author list is C. Murphy, A. Vartanian, F. Geiger, R. Hamers, J. Pedersen, Q. Cui, C. Haynes, E. Carlson, R. Hernandez, R. Klaper, G. Orr, and Z. Rosenzweig,

It’s available as Open Access right now at http://dx.doi.org/10.1021/acscentsci.5b00182

The Analytics of FaceBook and what it says about you (and others)

There’s no way that I could possibly go into all that FaceBook (and Google) knows about me from the amalgamation of all the sites I have visited and the content that I have produced, not to mention what they gather from the data of all of my friends and acquaintances about me through their own links and hits to my material. But I do want to hit on one crazy connection that intrigues and scares me at the same time.

FaceBook presumably tracks the degree to which each of my posts has been clicked in any way by my friends, whether they simply read it, clicked on the forwarding link, liked it, commented on it, shared it, etc. (Note that while I may not know who lurked it, FaceBook does!) That means that there is a way for FaceBook to tell me what aspect of my on-line personality is of interest to each of my friends. Presumably each of these faces is different and is somehow a reflection not just of myself but also that of my fB friend. There’s clearly some statistical error and noise among these faces because each is contingent on the overall activity of a given fB friend and their strategy for digesting fB content. Nevertheless, it seems nearly unfathomable that fB has a way to access the degree of my multiple personalities by way of running statistics on these faces. In turn, such data would presumably be possible for me to obtain a better understanding of what I really have in common with a given friend. Chances are that knowing this would make the relationship weaker rather than stronger as I might be tempted to zero in on only the known overlaps rather than the discovery of new commonalities. But how will I or you actually respond to this type of information when fB eventually gives us this (new) feature (whether free or charged)?
