NSRC Events

NSRC Workshops

The NSRCs hold joint workshops to share research and user projects that are ongoing at the five centers. These exchanges of information have provided the staff at the NSRCs with the opportunity to learn about topics/thrusts in nanoscience at the other nanocenters and to develop an understanding of the different areas of expertise among the staff members. They have also facilitated discussions towards possible future areas of collaboration between the centers and provided basic information so that potential NSRC users can be directed toward the optimal center and staff to meet their research needs.

Ultrathin Nanoporous Coatings Prevent Metals from Rusting

The oxidation (rusting) of a ruthenium surface was studied as a function different ultra-thin coatings comprised of inexpensive materials (silicon and aluminum). A collaboration among researchers from the CFN, NSLS-II, and U. of Minnesota found that ultrathin (~0.5 nm), nanoporous, and crystalline coatings comprised of these materials (aluminosilicates that act as model two-dimensional molecular barriers), prevent the surface from oxidation at conditions under which the ruthenium metal would normally oxidize.

• These results will inform our understanding of chemical reactions within confined nanospaces.
• Discovering the rust-suppressing property of these zeolites, one the most widely used catalyst materials in the chemical industry, could have profound impact on the modeling and comprehension of industrially relevant reactions, such as the conversion of methanol into gasoline.
• This is the first publication from the CSX-2 beamline, which started commissioning in 2015 and will begin general user operations in the summer of 2016.

Producing Valuable Chemicals from Waste Carbon Dioxide

Scientific Achievement

A simple method was used to fabricate copper surfaces that efficiently convert carbon dioxide (CO2) into useful industrial chemicals. Oxidizing the surface of copper with a plasma creates a nanostructured surface that becomes highly selective to the formation of ethylene (C2H4). The ethylene production was found to depend on both the surface roughness and the copper species that exist on the surface due to the plasma pre-treatment. This insight could lead to the production of cost-effective routes toward the synthesis of C2H4 from CO2.

The Curious Behavior of Proteins in Confined Spaces

Scientific Achievement

Preserving the structure and bioactivity of immobilized proteins is of current interest for biosensors and drug delivery platform development. To explore how proteins behave under confinement, nanoporous block copolymer films, with uniform pore size, shape (stripes and cylinders), and chemistry, were filled with proteins. After filling, the stiffness and activity of the proteins were examined as functions of pore size and shape. Proteins, confined within polystyrene (PS) nanopores, were found to be stiffer than proteins that are contained inside larger, submicron, poly(methyl methacrylate) pores. These results suggest that protein stiffness correlates to the extent of confinement, which subsequently influences a protein’s activity and elasticity. This information about protein-functionalized polymers can be used to improve the scientific community’s comprehension of the interactions among and the function of proteins and engineered surfaces.

Wafer-Scale Highly Aligned Functional Carbon Nanotube Films.

“Low-tech” solution-based route to high-performance carbon nanotube thin films.  

The Science

This is a rapid, facile, route to macroscale carbon nanotube thin films exhibiting a high degree of alignment.  Harnessing a spontaneous self-alignment mechanism creates ideal polarizers in the terahertz frequency range.

The Impact 

This “low-tech” solution offers a rapid, facile route to macroscale carbon nanotube thin films exhibiting a high degree of alignment.  This harnesses a spontaneous self-alignment mechanism, enabling thin film electronics, optoelectronics and ideal polarizers from THz to visible light frequencies. 


The one-dimensional character of electrons, phonons and excitons in individual single-walled carbon nanotubes leads to extremely anisotropic electronic, thermal and optical properties. Despite significant efforts to develop ways to produce large-scale architectures of aligned nanotubes, macroscopic manifestations of such properties remain limited. Here, we show that large (>cm2) monodomain films of aligned single-walled carbon nanotubes can be prepared using slow vacuum filtration. The produced films are globally aligned within ±1.5¡ (a nematic order parameter of ∼1) and are highly packed, containing ~1X106 nanotubes in a cross-sectional area of 1 μm2. The method works for nanotubes synthesized by various methods, and film thickness is controllable from a few nanometres to ∼100 nm. This approach creates ideal polarizers in the terahertz frequency range. Combining this method with recently developed sorting techniques allows for highly aligned and chirality-enriched nanotube thin-film devices, with applications as efficient polarizers and thin film transistors for optoelectronic applications.

Self-Assembled Nanocomposites for Improved Optical Metamaterials.

A different approach toward construction of electromagnetic metamaterials using self-assembled, vertically aligned nanocomposite films.

The Science
The current methods for fabricating metamaterials require the fabrication of artificial cells that involve the use of both specific materials and patterning process. We have used a direct growth of self-assembled nanocomposites for fabricating metamaterials which is advantageous compared with commonly used methods.

The Impact 
Self-assembled metal embedded in oxide nanocomposites provide an exciting new material platform to control and enhance the optical response at nanometer scale. Such nanocomposites open unprecedented possibilities for the development of nanoscale photonic materials and enhance light-matter interactions at the nanoscale level for novel applications such as super-resolution imaging (hyperlenses), cloaking, and hyperbolic propagation. 

We demonstrate a self-assembly approach to fabricating nanoscale metamaterials that are built on vertically aligned conducting metallic gold (Au) nanopillars embedded in oxide such as barium titanium oxide (BaTiO3 or BTO) matrices using a one-step deposition method. Such nanocomposites permit the control of the density, size, and alignment of metallic Au nanopillars. In other words, the key feature of such nanocompiste thin films is their anisotropic and largely tunable optical properties due to the controllable microstructures of the composite. Optical spectroscopy measurements supported by theoretical simulations reveal strong broad absorption features of the films.  Our results illustrates that there are many advantages of vertically aligned metal-oxide nanocomposite to fabricate large scale and novel nanoscale photonic materials such as metamaterials for applications including super lenses, biological sensing, subwavelength imaging, and cloaking devices.

Nanometer-scale mapping of irreversible electrochemical nucleation processes on solid Li-ion electrolytes.

Nanoparticles of lithium metal formed on the surface of a solid state lithium ion electrolyte by an atomic force microscope.

Borophene: Atomically Thin Metallic Boron

A team of scientists at the Center for Nanoscale Materials, Northwestern University and Stony Brook University has for the first time created a two-dimensional sheet of boron known as borophene. Borophene is an unusual material because it shows many metallic properties at the nanoscale even though three-dimensional, or bulk, boron is nonmetallic and semiconducting. Because borophene is both metallic and atomically thin, it holds promise for possible applications ranging from electronics to photovoltaics. While other two-dimensional materials appear smooth at the nanoscale, borophene looks like corrugated cardboard, buckling up and down depending on how the boron atoms bind to one another. The “ridges” of this cardboard-like structure result in anisotropy, where a material’s mechanical or electronic properties become directionally dependent. Experimental measurements consisted of scanning tunneling microscopy with X-ray photoelectron spectroscopy and transmission electron microscopy to both obtain a view of the surface of the material and verify its atomic-scale thickness and chemical properties.
