NanoArt Competition

Thank you to all of our “Nano” Artists that participated in this year’s competition. In addition to the 1st, 2nd and 3rd Place Winners of the Cash Prizes, all entries delineated with a “*” will be featured on the 2018 Singh Nanovation Playing Card Deck.

 

1st Place*

“Broken ALD Pillars” by John Cortes

There is beauty in destruction. This image represents ALD pillars that have been destroyed through sample handling. These are about 5-10 um in diameter and about 50 nm in wall thickness.


2nd Place*

MXene Ugly Duckling”  by Sin Saleesha

Colorized Colorized SEM image of 2D molybdenum carbide (Mo2C) MXene powder, which is shown to have a very small overpotential for hydrogen evolution reaction (HER). The entire 2D surface (basal plane) of each single-layer MXene flake is catalytically active, which is promising for developing efficient noble-metal-free catalysts. The width of the image is ~25 µm. Saleesha Sin, Pavel Lelyukh, Babak Anasori, Yury Gogots.


3rd Place*

“Vanadium Oxide Petals” by Mallory Clites*

Bilayered vanadium oxide has a flexible layered crystal structure that allows for the intercalation of various ions and molecules. In this image, a large, positively-charged organic molecule, cetyltrimethyl ammonium, has been inserted into the space between vanadium oxide layers. After synthesis, the vanadium oxide forms thick nanobelts that wrap together tightly to form the shape of petals or leaves, resulting in the design shown.

Bugs? Ores? Islands?” by Yingyi (Olina) Liang

Actually, these are two sand grains (of about 200 μm diameter) embedded on a lead surface created by metal casting in a sand mould. Image obtained using FEI Quanta 200 FEG Environmental-SEM and elemental composition determined by energy dispersive X-ray spectroscopy (EDX).


Oriental Columbine” by Sohee Moon

Image that I took of a Oriental columbine flower.


20,000 leagues under the Transmission electron microscope (TEM)” by Casey Schwarz

This is a dark field TEM image collected from a powder specimen of a base 20GeSe2-60As2Se3-20PbSe glass. The composition is within the immiscibility zone of its phase diagram, so the starting glass specimen upon its quenching process is phase-separated. The sub-wavelength, secondary phases within the shard shown in the TEM image are Pb-rich while the matrix is Pb-deficient. Thermal treatment of this glass system makes the secondary phases selectively crystallized while maintaining the matrix glassy, thereby inducing high refractive index crystals within low refractive index matrix. Since the number density of the high refractive index crystals can be spatially varied using a variety of methods, enabling the effective refractive index of the entire nanocomposites likewise spatially varied, this glass-ceramic material has been considered promising for gradient refractive index (GRIN) lenses. It also looks like a giant octopus leg to a small diver.


“A Sea of Microbubbles” by Katie Pulsipher

Microbubbles stabilized by recombinant protein can be used for ultrasound imaging and antivascular therapy. The more monodisperse the bubbles, the more efficient the microbubble agent, making this an ideal sample.


“Cane” by Yingyi (Olina) Liang

Early modern (16th century) metal casting process reproduced! People were using it to make decorative pieces. On this picture you can see an accidentally embedded sodium chloride residue on tin metal (one of the soft metals traditionally used for casting). I wonder, what other shapes the residues form on old artifacts we see in museums…Image obtained using FEI Quanta 200 FEG Environmental-SEM and elemental composition determined by energy dispersive X-ray spectroscopy (EDX).


Basketweave-Pattern Nanocardboard Plates” by Chen Lin and Sam Nicaise*

It is a colored SEM image showing the nanocardboard structure, a hollow ALD sandwich plate with basketweave internal webbing connecting two planar face sheets. It has nanoscale plate thickness, microscale plate height and macroscale lateral dimensions. More importantly, it has both high bending stiffness and ultralow areal density which enables many potential applications.


“Cookie Cutter” by Yuan Li*

A high-aspect ratio (20:1) KMPR1050 photoresist microstructure.


“DNA Translocation Through 2D Nanoporesby Gopinath Danda

Artistic rendition of translocation of a double stranded DNA in an electrolyte solution through a nanopore in a suspended two-dimensional membrane. The nanopore is drilled using a focused electron beam in a transmission electron microscope. Such nanopore sensors can be used to detect and characterize nanometer-sized molecules, like DNA.


“Drying Pattern of AuNP Clusters” by Elizabeth Dempsey

Self-assembled clusters of ultrasmall (<3nm) gold nanoparticles, coated with an amphiphilic near-IR dye, and dried on a TEM grid. Here, as the clusters dry and flatten, they display an unusual, non-circular pattern.


“Phantom of the Silica” by Lin Du*

The picture is on a silica substrate. In the middle is exposed copper material shiny in the dark.


“Labrum of Mosquito” by Sohee Moon

This is a labrum of a mosquito.


NanoSkittles Bubbling Up from the Ground” by Sam Nicaise

These microspheres of NiP were poorly depositing onto the substrate, and formed a “vein” of candy for all the nanoelfs to enjoy in the middle of the night.


“Messy Room” by Yingyi (Olina)Liang

Oh, what a mess! Trying to age something quickly. Don’t try to grow up too fast! A lead sample was soaked int 0.6 M NaCl solution for 48 hours (to imitate being submerged in the ocean), and then washed with ethanol. The salt crystals remain on the metal surface and form different shapes. Image taken with FEI Quanta 200 FEG Environmental-SEM.


Drying pattern of AuNP Clusters” by Elizabeth Dempsey

Self-assembled clusters of ultrasmall (<3nm) gold nanoparticles, coated with an amphiphilic near-IR dye, and dried on a TEM grid. Here, as the clusters dry and flatten, they display an unusual, heterogeneous pattern.


“Nano Star Wars Tri-Wing” by Sam Nicaise

What happens when you let your 3D-structured alumina metamaterial jump away from the silicon? 100-nm thick space-aged vehicles take shape!


Pyrolusiteby Brendan Hayes-Oberst*

This image is of pyrolusite that crystallizes with a hexagonal rod like morphology. This material has the chemical formula MnO2. It is a tunnel manganese oxide that is composed of edge and face sharing MnO6 octahedrons. The tunnel size of this material is about 2.3 A by 2.3 A.


Pd Doping of Bi2Se3 Nanostructure” by Jerome Mlack

Colorized transmission electron microscope image of Topological Insulator bismuth selenide nanostructure which was been locally and controllably doped with palladium metal using thermal annealing. The palladium doped regions become superconducting at sufficiently low temperatures, providing a new method for fabricating quantum junctions directly into a material and potentially building quantum computing circuits.


“Microbubble Galaxy” by Katie Pulsipher

Microbubbles stabilized with recombinant protein and Pluronic surfactant can be used for ultrasound imaging and therapy. Ideal samples in these applications are monodisperse, but a polydisperse sample can be visually stellar.


“Pollen Pattern” by Asja Radja *

Pollen grains have remarkable surface structures which can only be seen in detail in an electron microscope. Pictured is the pollen of the Passiflora incarnata (passion vine) plant. We study the physical pattern formation mechanisms which lead to these intricate and diverse patterns on a sphere.


“Pollen Patterns” by Asja Radja*

Pollen grains have beautiful surface patterns that can only been seen in detail in an electron microscope. In this image we show three different species with strikingly different, stable patterns: top left, Spathiphyllum (peace lily); top right, Passiflora (passion vine); bottom, Aster (daisy).


“The QNF Monster Lurks” by Sam Nicaise*

The lore of the QNF monster is young but strong. People speak of it’s ability to demise their best devices, eat electrical connections, and disappear important samples. The scariest part – it’s microscope and supposedly deadly! NiP microspheres depositing on substrate after coalescing from suspension.


“The ‘Platinum’ Wedding Band” by Yuan Li

A high aspect ratio (10:1) KMPR1050 photoresist microstructure.


Clusters of Polydisperse AuNPsby Elizabeth Dempsey

Self-assembled clusters of ultrasmall (<3nm) gold nanoparticles, coated with an amphiphilic polymer, and dried on a TEM grid. Here, the impure polymer caused chemical reduction of a fraction of gold particles, creating a subset of much larger gold particles with unusual geometry. The batch was rendered useless, but the image was intriguing.


“Would You Like a Strawberry?” by Sohee Moon*

This is an image of 2 drug particles fused to another. We wanted to test if the particles have the same shape and if they are evenly distributed, but interestingly, a defective particle stuck to a non-defective one and created this image.


“Lotus Leaf” by Sohee Moon

This is a lotus leaf.
