“Science Outside the Lab” brings a small cohort of graduate student scientists and engineers to Washington, D.C. to explore the relationships among science, innovation, policy, and societal outcomes. This customized free one week version (June 4-10, 2017), sponsored by the Nanotechnology Collaborative Infrastructure Southwest (NCI-SW), will investigate the context of nanotechnology decision-making in government and business at the local, state, federal, and international levels. During the week-long workshop participants meet and interact with groups of people who fund, regulate, shape, critique, publicize, and study nanotechnology and other emerging technologies. This includes people like congressional staffers, lobbyists, funding agency officers, regulators, journalists, academics, museum curators, and others.

Researchers at Duke University recently published a paper in Advanced Materials describing the development of a technique to detect light across the electromagnetic spectrum. As opposed to using materials that absorb specific wavelengths of light, silver nanocube structures trap different types of light. This can be controlled by changing the size and arrangement of the nanocubes. To learn more see the Duke press release or read the article.
“Toward Multispectral Imaging with Colloidal Metasurface Pixels“
Jon W. Stewart, Gleb M. Akselrod, David R. Smith, and Maiken H. Mikkelsen
Abstract: Multispectral colloidal metasurfaces are fabricated that exhibit greater than 85% absorption and ≈100 nm linewidths by patterning film-coupled nanocubes in pixels using a fusion of bottom-up and top-down fabrication techniques over wafer-scale areas. With this technique, the authors realize a multispectral pixel array consisting of six resonances between 580 and 1125 nm and reconstruct an RGB image with 9261 color combinations.
Images captured using electron microscopes housed in RTNN’s Shared Materials Instrumentation Facility (SMIF) at Duke are featured in a recent Duke News article. Read the whole story here and see amazing images of horseflies and weevils at 300,000x magnification.
Led by RTNN director Dr. Jacob Jones, a team of researchers from NC State, UNC-CH, Duke, and RTI has been announced as a GRIP (Game-Changing Research Initiative Program) awardee for their project “Water Sustainability through Nanotechnology: Nanoscale Science and Engineering at the Solid-Water Interface.” Water is a fundamental requirement for life. However, universal access to clean water has become a crisis facing society, evidenced by continuing droughts and contaminated water supplies in major population centers. There is an emergent need for innovative, sustainable technologies to improve and maintain worldwide availability and quality of clean water. Development of new materials, membranes, and separation processes are essential to more efficiently create drinking water from salt water (desalination), reclaim clean water from waste and local streams (wastewater and point-of-use treatment), and to recover contaminants of value from water (resource recovery). Engineered nanotechnologies and nanomaterials can be used to uniquely address many emerging challenges in water sustainability due to their high surface area, reactivity, and surface and interfacial phenomena. Empowered by a multi-agency Nanotechnology Signature Initiative released in March 2016, the team will launch an ambitious effort to catalyze several interrelated, game-changing research activities for substantially increasing water availability at lower cost. The effort will position NC State, RTI, and partnering institutions including Duke and UNC-CH as a leading team at the water-nano nexus.
More information about the GRIP and other awardees can be found in the NC State press release and on the GRIP website.
The 2016 Awards for “Best Papers” utilizing the Analytical Instrumentation Facility (AIF) were announced in November and went to Yanqi Ye from the group of Zhen Gu (BME) for a publication in Advanced Materials introducing a microneedle-based cell therapy and Kelly Stano from the group of Philip Bradford (TECS) for work published in Small on nanotube networks. Congratulations to these authors on their excellent work! Previous award winners can be found here.

Congratulations to our image contest winner, Yaewon Park, for her entry, CaCO3 mineralized poly(vinyl alcohol) nanofibers.
This picture shows a Scanning Electron Microscopy (SEM) image of CaCO3 nanoparticle clusters encrusting electrospun poly(vinyl alcohol) nanofibers. This structure resembles bone structure which consists of collagen fibrils and hydroxyapatate crystals attached along them.
My current research is on surface coating of nanofibers with CaCO3 particles by mimicking bone formation process. My research is expected to give a light on environmentally friendly coating of functional textiles and water filtration materials. Nanofibers were dipped in CaCl2 solution and Na2CO3 solution alternatively for 10 times. This image shows that spherical CaCO3 particles surrounded the circumference of nanofibers. This interesting structure is similar to human bone structure.

Joshua Zhou: Coral Reef The viewing window of a scanning electron microscope halts before a field of “coral reef”, ordered clusters of vanadium oxide nanorods. Another rod rests on their surface, like a fish seeking shelter from predators. Characterizing the shape of vanadium oxide nanomaterials can account for changes in their thermochromic properties.
This work aimed to form a titanium oxide-vanadium oxide composite doped with magnesium in order to increase the infrared blocking capability of thermochromic films. Efficient thermochromic films can be used in smart windows to block heat-bearing infrared radiation on hot days, while phase-shifting in cold weather to allow warmth in from sunlight. Phase shifts are temperature dependent and rely on no external supply of electricity. This can help reduce air-conditioning bills while maintaining room comfort.
Yanqi Ye: Smart Melanoma Patch Fluorescence imaging of a representative microneedle patch that contained FITC-aPD1 loaded NPs for melanoma treatment. Despite recent advances in melanoma treatment through the use of anti-PD- 1 (aPD1) immunotherapy, the efficacy of this method remains to be improved. Here we report an innovative self-degradable microneedle (MN) patch for the sustained delivery of aPD1 in a physiologically controllable manner. Moreover, this administration strategy can integrate with other immunomodulators (such as anti-CTLA- 4) to achieve combination therapy for enhancing anti-tumor efficacy.
Researchers from the lab of RTNN principal faculty member Greg Parsons have created a material capable of degrading chemical warfare agents (CWAs). Uniform coatings of metal-organic frameworks (MOFs) were grown on electrospun nanofibers, forming unique kebab-like structures. These MOFs were able to break down CWAs making them harmless. The team conducted much of their characterization work at the Analytical Instrumentation Facility, a member of the RTNN. More information about the work can be found below and in the NC State Press release.
“Ultra-Fast Degradation of Chemical Warfare Agents Using MOF–Nanofiber Kebabs”
Junjie Zhao, Dennis T. Lee, Robert W. Yaga, Morgan G. Hall, Heather F. Barton, Ian R. Woodward, Christopher J. Oldham, Howard J. Walls, Gregory W. Peterson, and Gregory N. Parsons.
Abstract: The threat associated with chemical warfare agents (CWAs) motivates the wardevelopment of new materials to provide enhanced protection with a reduced burden. Metal–organic frame-works (MOFs) have recently been shown as highly effective catalysts for detoxifying CWAs, but challenges still remain for integrating MOFs into functional filter media and/or protective garments. Herein, we report a series of MOF–nanofiber kebab structures for fast degradation of CWAs. We found TiO2 coatings deposited via atomic layer deposition (ALD) onto polyamide-6 nanofibers enable the formation of conformal Zr-based MOF thin films including UiO-66, UiO-66-NH2, and UiO-67. Cross-sectional TEM images show that these MOF crystals nucleate and grow directly on and around the nanofibers, with strong attachment to the substrates. These MOF-functionalized nanofibers exhibit excellent reactivity for detoxifying CWAs. The half-lives of a CWA simulant compound and nerve agent soman (GD) are as short as 7.3 min and 2.3 min, respectively. These results therefore provide the earliest report of MOF–nanofiber textile composites capable of ultra-fast degradation of CWAs.
