Research

Recently, we have been using Near Edge X-Ray Absorption Fine Structure (NEXAFS) spectroscopy to study polymer-CNT composites. In the last few decades, a myriad of one-dimensional nanostructures have been produced. From Carbon nanotubes (CNT) to SnO, novel properties at the quantum mechanics frontier and tailored chemistries hold the promise of improved devices with higher expectancy than their thin-film counterparts. This is the case of CNT composites and GaN.

The recent development by our group of CNT composites and GaN fibers by electrospinning techniques hints at the possibility of affordable mass manufacturing with optimum integration in microsystem technology environments. Ongoing efforts aim at improving fabrication and characterization to correlate fabrication with structure and, ultimately, with properties.

In addition, we are interested in the manufacturing-with microtechnologies-of tools useful for the biomedical sciences. We have successfully ion-beam-polished glass and Si pipettes that can successfully penetrate mouse cells in the absence of drills, and yielding viability until blastocyst stage.

Atomistic studies of smart composites smartcomposites

Nano-optical mechanical actuation based on nanotube-enriched polymeric materials is a much sought-after technology. In this scheme, light sources promote mechanical actuation of polymeric materials producing a variety of nano–optical mechanical systems such as tactile displays, artificial muscles, and nano-grippers among others. Electro-actuation has received some attention in the sensor and actuator community, and the MRS dedicated the March 2008 bulletin to this topic (Figure 1a). However, Opto-mechanical actuation is preferred to electromechanical transduction in multiple environments because it is wireless, provides low noise, and allows for electro-mechanical decoupling. It also has the potential for much higher spatial resolution.
Recently, we have suggested the possibility of photo-mechanical actuation of CNT composites by electrospinning (submitted to SPIE NOMS 2011) as seen in (Figure 1b). Photomechanical actuating bundles in (Figure1b) were weaved with sub-micrometer wide fibers shown in (Figure 1c).Physical mechanisms behind photomechanical actuation are not well understood; torsional-orientation effects of the MWCNT within the matrix have been proposed (Figure 1d, Ahir and Terentjev, 2005). Photo-mechanical actuation is clearly an emerging field and has been launched to the main research arena mostly by the hand of our dissemination efforts at the SPIE’s Nanotechnology meeting in August 2011 (spie.org/OP116).

Nanofabrication by electrospinning nanofabricationbyelectrospinning

The PREM-UPenn team has followed the footsteps of Professor MacDiarmid’s in electrospinning. This is a convenient technique for the production of composites and polymer-derived-ceramics. We have pioneered the production of polycrystalline GaN fibres (reported at the undergraduate research conference NCUR 2008) by electrospinning, and we have recently achieved highly crystalline grains (to be submitted to Advanced Materials), as seen in (Figure 4).
The production process consists of electrospinning of a Ga-rich polymer precursor and tailored thermal treatments to yield wurtzite GaN (SPIE Scanning Microscopy 2010 and 2011). Upon annealing, fibers are brittle (Figure 4a) and polycrystalline (Figure 4b). Adjacent grains can be highly misoriented (Figure 4c), with 3D growth favoring grains stacking up in the vertical direction complicating analysis, as seen in (Figure 4d), where atomic contrast from the dominant set of planes in area1 can be observed convoluted with the weaker information of atomic planes highlighted in area 2.

Nanobiotechnology

The advent of studies down to the sub-cellular level in the life sciences is driving the development of suitable tools. Micro-nano technologies such as ion beam milling are quickly finding their way to produce tools capable of handling and probing life cells and sub-cellular structures. We have pioneered the use of Ga-ion beam milling to sharpen conventional glass pipettes (Figure 5a) and tips of microfluidic devices (Figure 5b) and test them in live mouse oocytes and embryos in absence of piezo-electric drills (Figure 5c), suggesting promising biocompatibility levels as seen in (Figure 5d) and paving the way for on demand biomedical tools with tailored functionalities in subcellular probing (Biomed. Microdev. 2010, to be submitted to Biomed. Microdev. 2011, Biomedical Engineering, In Tech Publishers 2011). In addition, both conventional and micropipettes were structurally sound, opening the door to the manufacturing of mechanically resilient structures by ion beams.
Following the trend initiated by Kometani and coworkers, I propose to micro-nano manufacture suitable tools for the biomedical sciences and test their mechanical performance in context-relevant scenarios.

Material simulations materialsimulation

As the quest toward novel materials proceeds, improved characterization technologies are needed. In particular, the atomic thickness in graphene and other 2D materials renders some conventional technologies obsolete. Characterization technologies at wafer level are needed with enough sensitivity to detect strain in order to inform fabrication.
In this work, NEXAFS spectroscopy was combined with simulations to predict lattice parameters of graphene grown on copper and further transferred to a variety of substrates. The strains associated with the predicted lattice parameters are in agreement with experimental findings. The approach presented here holds promise to effectively measure strain in graphene and other 2D systems at wafer levels to inform manufacturing environments.

Education

Eva M. Campo Assistant Education Director, Laboratory for the Research on the Structure of Matter, University of Pennsylvania (USA).
Country of Birth: SPAIN.
Educational background:
PhD Materials Science and Engineering, Lehigh University.
MS Theoretical Physics, University Complutense of Madrid.

Who or what inspired you to work in science/engineering ?
My earliest memories in a laboratory date back to elementary school. My Grandfather was a chemist in an industrial laboratory (Zeltia Group) and we used to visit the lab together. I was intrigued by the sophisticated glassware and complicated equipment. At school, I was really into physics and math.

* Primary responsibilities of your current job ?
I design programs targeted at increasing participation in the sciences, with an emphasis on underserved populations. In the PREM program at the University of Puerto Rico at Humacao, I co-advise undergraduate students in their research activities and help tailor their education/research curriculum. As a scientist, I manufacture tools to manipulate live cells, and investigate new materials properties, such as the movement in smart materials irradiated by light.

Biggest obstacle or challenge that you have faced in your career ?
When I fi rst became an Assistant Professor in Barcelona, Spain, my entire professional trajectory had taken place in the US. I was asked to lead the assembly of a multidisciplinary team across Europe. As team director, I realized the administration of budgets and scientifi c policies vary greatly for different countries and institutions within a country. This was particularly challenging when trying to unify the different criteria to the requirements set by funding agencies. I saw these diffi culties simply as a sign of diversity. With this perspective, the task became an enriching experience. I got to see how science and scientifi c policies are handled across Europe and worked out ways for all of us to work together. * This education paper co-authored by the NOMS-PREM-PENN consortium is a learning-based study. This study will explore education and dissemination strategies for mechanical actuation as a novel phenomenon. We will present a work plan for the dissemination of photo-mechanical actuation to society at large; from K-12 to the general public. The work plan will be designed in accordance to the logic model and will include a thorough assessment plan. An important thread in this design will be unveiling the commonalities behind actuation triggered by multiple stimuli (thermal, chemical, optical, etc.), paving the way for innovative nanotechnology applications, and favoring consumer acceptance, in accordance with NSF and FP7-European Commission directives.

Education at LRSM students at work

I recently developed a good understanding of how contextual information and strategic exposure to new topics can construct the line of thought in a successful education program. As Director of Education at LRSM I am designing education programs following the logic model.

The first edition of the UPenn-Girard Science Week was launched for 7th graders between the 6th and 10th of June 2011.
The objective of the camp was to expand the frontiers of STEM comfort-levels amongst 7th graders and enable them to become engaged in the pursuit of science. Affection has been promoted by a variety of mechanisms, such as the inclusion of age-relevant hands-on activities (jello optics, thermal properties of soil and of food, mechanical properties in dental brackets, robots) and by tailoring content to the adequate intellectual maturity, for which we are working closely with Girard’s Science Teachers. But the back-bone of the program relies on the anticipation to build a robot the last day of the program. Indeed, the first day’s activities featured a visit to the Robotics Lab at the University of Pennsylvania, and students are told they will get to build their own robot (and keep it) at the end of the week.
To accomplish this, they will learn about components featuring adequate mechanical properties, energy requirements for optimal performance, and additional active (motors) and passive (sensors) behavior.

This strategy has been very well reviewed by the CORE team at Cornell-the partnership assisting MRSEC directors design and evaluate our education portfolio. A flow chart describing this strategy can be found in the ANNEX
