CFN 2023 Calendar

The Center for Functional Nanomaterials 2023 calendar features staff and user creations submitted in the 13th Annual CFN Image Contest. The contest gives us a chance to express our artistic sensibilities in two categories: Scientific and Technical (micrographs and images relating to CFN research) and Life at the CFN (images of the facility, instrumentation, offices, etc).


This image is not real!

It was generated by artificial intelligence (AI) tasked with dreaming about nanomaterials. This image was not generated using CFN equipment. It was generated entirely by computer. (2nd Place Winner)

Gold nanoparticles can be deposited on SiO2 surface with the protection of helium nanodroplets that evaporate after landing. An electric fi eld formed at the gold/SiO2 interface due a charge-transfer can facilitate catalytic reactions. CFN instruments used: Atomic Layer Deposition Tool, Dual Beam Scanning Electron/Focused Ion Beam microscope and Rapid thermal processing system were involved.

The study addressed the challenge of stability of nanoparticles (NPs) in physiological media or organic solvents. Designed organic molecules (peptoids) can act as molecular stabilizers for NPs in varied solution environments and at liquid interfaces, while providing a small shell thickness. The particle “toughness” is represented by its ability to resist a shark. CFN capabilities used: CFN Materials Synthesis and Characterization Facility, lab SAXS, TEM, and partner SAXS beamlines at NSLS-II.

Borophene in Top Form

Two-dimensional layers of boron atoms have been grown on a variety of surfaces, typically noble metals. Borophene sheets can form different polymorphs with different properties, which is attractive for applications, but for practical use larger fl akes with weake metal–substrate interactions are required. Now, Rongting Wu, Sohrab Ismail-Beigi, Ivan Božovic, and co-workers have synthesized micrometer-scale single-crystalline borophene on a square-lattice Cu (100) surface.

Hybrid Neuromorphic Resistive Memory

This work demonstrates control of device switching parameters and reduced stochastic switching, which are criticaltechnology issues for resistive random-access memory (RRAM). These devices show promise as multi-level memories, which are essential elements in neuromorphic computing. The hybrid material was created by vapor-phase infiltration of alumina into silver-doped SU-8 — a conventional photoresist. The CFN Electron Microscopy, Nanofabrication, and Materials Synthesis & Characterization Facilities were used in this study.

A network of interpenetrating Carbon Nanotubes formed from a random array of multi-wall CNTs using high fl ux rate xenon ion bombardment with an energy of 2.87 keV and a total fl uence of 2.23X10^18 ions per square cm. CFN instrument used: Hitachi 4800 Field Emission SEM

Magnetic domain found at the core of a micron-sized block of strontium iridate: This picture, made by Longlong Wu in the CMPMS department, is of a strontium iridate crystal prepared by FIB in the CFN. It is 1.3 microns on a side. It was subsequently imaged by X-ray Bragg coherent diffraction imaging. It shows a magnetic domain inside the crystal.

This image was done by digital drawing and coloring over a base TEM image of turbostratic graphene taken with CFN’s FEI Talos F200X by Kim Kisslinger as part of the project in our user proposal. The edited image depicts a person having their recharge time enveloped in a red heavy blanket along their pets: a cat and a dog. It refl ects the importance of taking time to recover our energy to keep forging our path.
