Trends in Graphene and Graphene-based nanocomposites

  1. Image 
Since graphene was isolated by a group of physicists from Manchester University, UK in 2004, interest in graphene research throughout the world has skyrocketed.  This huge activity stems from graphene’s unusual and extraordinary electrical, thermal, and mechanical properties.  Professor Geim, who was instrumental in the separation of graphene, recently commented, “Graphene is a wonder material with many superlatives to its name”.  Why such glorification of graphene as a material?  Because it is the thinnest known material in the universe and its strength is the highest ever measured1. Prior to its separation into platelets, graphene was a controversial material and the subject of much speculation.  Many believed that graphene could not exist as a freestanding sheet, and yet it was studied theoretically for over 6o years. The results of this intense work over the years have been comprehensively documented in an article by Geim and Novoselov2.  Particularly noteworthy is the research, at MIT, of Gene Dresselhaus and Mildred Dresselhaus who began work with graphite (multi-layered graphene) several decades ago.  The results, until 1980, of the Dresselhaus team on graphite intercalated compounds have been described by these authors themselves3.  Today graphene’s unique structure allows for a wide spectrum of applications in a variety of fields while giving researchers an unprecedented opportunity for fundamental physical science. Picture on the top left show false-color 3-D rendered TEM image of isolated hydrogen atoms (purple-tipped) and an isolated carbon atom (red-tipped) on a graphene membrane ("Courtesy Zettl Research Group, Lawrence Berkeley National Laboratory and University of California at Berkeley"). This article aims to capture and convey in a few words the excitement provided by some of the interesting trends observed in research on graphene and graphene-based polymer nanocomposites (GPNC).

Improving processing and properties of polylactic acid

ImagePoly(lactic acid) or PLA is a thermoplastic polymer made from the polymerization of lactic acid derived from the fermentation of natural sugars from corn, beets, or sugar cane (Figure 1)1-3. The polymer is biobased and can also be composted under industrial compost conditions. With increasing interest in sustainability and finding alternatives to petroleum-based products, PLA is at the forefront of the current trend towards bioplastics usage.  PLA is being used as a replacement for many traditional PET and PS applications such as thermoformed packaging, fibers, card stock, foamed food trays and in blends with other thermoplastics such as polycarbonate for electronic or automotive applications. PLA is rapidly gaining increasing commercial acceptance and new applications are continually appearing on the market.

Publicizing Your Research

A practical guide for Publicizing your research/technical paper

How do go about publicizing a technical paper or a research document apart from presenting it at a conference or publishing it in a journal or in a magazine? Below is a method you can pursue to publicize your paper/technical research on the web and in print.

Submitting a “technical release”

Companies send press releases to publications to inform readers about their products and services; and you can do the same with a technical release about your technical paper or research. If you have lab notes that you are willing put into an intelligible document, this could be a valuable technical resource to others in your science/technology community. Just keep in mind that the science and technology will come under the scrutiny of your peers.

Aspects of Electron Beam (EB) Processing of Polymers

Of the many ways one can modify traditional polymers, electron beam irradiation (EBI) is one of the most attractive technique to the scientific and the industrial community, since it can profoundly affects the molecular structure providing polymeric materials with unique properties1-5.                           

The process has revolutionized the application of polymeric material in diverse areas including sterilization of medical devices, pollution control (treatment of sewage and sludge), food preservation, curing of cable insulations, manufacture of heat-shrinkable polymers, in orthopaedics, tire manufacturing and on1-4, 6,7.  The process is carried out with electron accelerators (EA) that provide energies between 75 eV and 10 MeV2,8,9. The radiation interacts with the polymeric material, knocking-off labile atoms from the polymer to generate radicals1, 2 on the carbon backbone of the polymer.   These radicals initiate reactions such as polymerization (e.g. curing of coatings), and cross-linking. Polymerization is possible with monomers having chemical unsaturations and proceeds through free-radical initiated addition reactions. Cross-linking results when two polymeric-radicals unite.   The target of the article is to summarize applications of the EB process to polymeric materials, describing the important benefits, how the process is quantified, how the best results can be achieved, current application trends and where the future lies.

Seeing through the plastic hype

What did Alexander Pope say? "A little learning is a dangerous thing; Drink deep, or taste not the Pierian Spring; there shallow thoughts intoxicate the brain; and drinking largely sobers us again." But the poet never had to think about drinking spring water out of a polycarbonate bottle, did he?

Bisphenol A (BPA), a chemical that can leach out of polycarbonate bottles, is clearly the "toxin du jour."

The Role of Molecular Architecture in the Development of new Melt-Processable Fluoropolymers

Polyvinylidene fluoride (PVDF) is a material of choice in the chemical process industry (CPI) for many reasons such as high resistance to harsh chemicals combined with its stability against UV light and heat, high electrical resistance and its high purity.  These properties make it a good material for insulating electrical wires, especially ones that get hot during it's use.  PVDF is used in the manufacturing of thick wall pipes, fittings and other components used in the transportation and storage of aggressive chemicals. In fact, high purity of PVDF allows its use in the semi-conductor business for transportation and storage of ultra-high purity water.
