Nanotechnology Moves From the Clean Room to the Classroom
August 21, 2017 | Argonne National LaboratoryEstimated reading time: 3 minutes
For years, scientists have been creating and tweaking extremely tiny materials atom by atom in special clean rooms scrubbed of debris. Students needed a Ph.D. to join the club and study those tiny materials in a field known as nanoscience.
Today, high school students can dabble in nanoscience thanks to the U.S. Department of Energy’s Argonne National Laboratory and industry partner United Scientific Supplies, Inc. High school students can get a hands-on introduction to nanoscience by growing copper wires at the nano-scale (one billionth of a meter) and micro-scale (millionth of a meter) using technology developed at Argonne’s Center for Nanoscale Materials, a DOE Office of Science User Facility, and produced by United Scientific.
“United Scientific is always on the lookout for interesting science breakthroughs that can be developed into new products for schools,” said Raj Soni, president of United Scientific Supplies. “We have long admired the work being done at Argonne and are pleased to make teachers and students aware of cutting-edge research in nanotechnology developed at the Center for Nanoscale Materials.”
With United’s Nanotechnology NextGen STEM Kit, students can grow pattern-shaped wires or structures using Argonne’s patented ultra-nanocrystalline diamond technology. The wires become the essential components to fabricate optical and electrical sensors, similar to the technology used in pressure sensors and other simple devices, in a matter of a few minutes.
Students are able to build micro/nanowires quickly and visualize the wires using an optical microscope, a standard tool in most high school science labs.
“When I was in high school, I was eager to explore inside the science lab,” said Anirudha Sumant, materials scientist at the Center for Nanoscale Materials. “I’d like to inspire that same excitement and eagerness by providing students with accessible, hands-on lab experiments that can draw their attention and stimulate critical thinking.”
The opportunity came when chemist Mike Zach, former Center for Nanoscale Materials facility user and current researcher at Oak Ridge National Laboratory, approached Sumant to develop a simple electrochemical method to mass produce micro- and nanowires. Sumant and Zach developed a process based on Argonne’s technology to adhere metal nanowires, in various shapes and configurations, on a reusable diamond template after simply removing the wires with clear tape. Students can use it again and again since diamond is chemically inert and does not strongly adhere to metals.
Sumant and Zach’s first version of the kit, NanoFabLab In a Box, won two awards in 2014 — an R&D 100 Award and a NASA Brief Tech Magazine Award.
Both partners believe the kit can boost students’ interest in science, technology, engineering and math (STEM) careers.
“The nanotechnology kit is available to teachers through our network of science products dealers across the United States,” said Soni. “Most components are designed for repeated classroom use.”
United Scientific is planning to continue work with Argonne to develop another NextGen STEM kit in the near future.
“Argonne’s Center for Nanoscale Materials is committed to groundbreaking science and inspiring the next generation of researchers,” said Center for Nanoscale Materials Director Supratik Guha.
About Argonne’s Center for Nanoscale Materials
The Center for Nanoscale Materials at Argonne National Laboratory is one of the five DOE Nanoscale Science Research Centers (NSRCs), premier national user facilities for interdisciplinary research at the nanoscale, supported by the DOE Office of Science. Together, the NSRCs comprise a suite of complementary facilities that provide researchers with state-of-the-art capabilities to fabricate, process, characterize and model nanoscale materials, and constitute the largest infrastructure investment of the National Nanotechnology Initiative. The NSRCs are located at DOE’s Argonne, Brookhaven, Lawrence Berkeley, Oak Ridge and Sandia and Los Alamos National Laboratories.

Trouble in Your Tank: Implementing Direct Metallization in Advanced Substrate Packaging
09/15/2025 | Michael Carano -- Column: Trouble in Your TankDirect metallization systems based on conductive graphite are gaining popularity throughout the world. The environmental and productivity gains achievable with this process are outstanding. Direct metallization reduces the costs of compliance, waste treatment, and legal issues related to chemical exposure. A graphite-based direct plate system has been devised to address these needs.
Closing the Loop on PCB Etching Waste
09/09/2025 | Shawn Stone, IECAs the PCB industry continues its push toward greener, more cost-efficient operations, Sigma Engineering’s Mecer System offers a comprehensive solution to two of the industry’s most persistent pain points: etchant consumption and rinse water waste. Designed as a modular, fully automated platform, the Mecer System regenerates spent copper etchants—both alkaline and acidic—and simultaneously recycles rinse water, transforming a traditionally linear chemical process into a closed-loop system.
Driving Innovation: Depth Routing Processes—Achieving Unparalleled Precision in Complex PCBs
09/08/2025 | Kurt Palmer -- Column: Driving InnovationIn PCB manufacturing, the demand for increasingly complex and miniaturized designs continually pushes the boundaries of traditional fabrication methods, including depth routing. Success in these applications demands not only on robust machinery but also sophisticated control functions. PCB manufacturers rely on advanced machine features and process methodologies to meet their precise depth routing goals. Here, I’ll explore some crucial functions that empower manufacturers to master complex depth routing challenges.
Trouble in Your Tank: Minimizing Small-via Defects for High-reliability PCBs
08/27/2025 | Michael Carano -- Column: Trouble in Your TankTo quote the comedian Stephen Wright, “If at first you don’t succeed, then skydiving is not for you.” That can be the battle cry when you find that only small-diameter vias are exhibiting voids. Why are small holes more prone to voids than larger vias when processed through electroless copper? There are several reasons.
The Government Circuit: Navigating New Trade Headwinds and New Partnerships
08/25/2025 | Chris Mitchell -- Column: The Government CircuitAs global trade winds continue to howl, the electronics manufacturing industry finds itself at a critical juncture. After months of warnings, the U.S. Government has implemented a broad array of tariff increases, with fresh duties hitting copper-based products, semiconductors, and imports from many nations. On the positive side, tentative trade agreements with Europe, China, Japan, and other nations are providing at least some clarity and counterbalance.
