Coalescing Micro-Droplets Win The 10th Annual Nikon Small World in Motion Competition

MELVILLE, N.Y., Sept. 15, 2020 /PRNewswire/ -- Nikon Instruments Inc. today unveiled the winners of the tenth annual Nikon Small World in Motion Photomicrography Competition. This year's first place prize was awarded to Mr. Kazi Rabbi and Dr. Xiao Yan and for their eye-catching video of micro-droplets (made of 80% water and 20% ethanol) coalescing. Rabbi and Yan's research at the University of Illinois at Urbana-Champaign is focused on creating surfaces that enhance the condensation and evaporation of liquid (repelling liquids from the surface they are on). People see condensation every day but are likely unaware of how enhancing condensation carries significant implications for sustainable living and creating energy efficient technology.
"Think about anything from keeping the pipes from freezing in winter to making your air conditioning unit run more efficiently," said Rabbi, "If we can develop surfaces and materials that better repel liquids, we can create appliances, power systems, and other technologies that require less energy to run. It could lead to a more sustainable future."
Rabbi and Yan conduct many experiments to see how liquids react to the functionalized surfaces (materials that can be used in the creation of new technologies) they have created, which is how they were able to capture this year's top video. "Much of our microscopy is focused on visualizing how liquid droplets or condensate droplets interact with such surfaces at micro scale." Yan said. This visualization is no easy feat to capture. The surface the droplets in the video are reacting to is one of Rabbi and Yan's own design.
To capture the video, the pair used transmitted light microscopy. The biggest challenge, they said, was controlling the micro-droplet generation and growth. They had to use a frequency-controlled micro-droplet dispenser and a high-speed camera interfaced with a microscopic lens to accomplish the task – all while focusing on the perfect plane and maintaining perfect lighting. It was a two-person job.
"This year's movies, and our winning video in particular, captures the spirt of Nikon Small World in Motion on the competition's 10th anniversary," said Eric Flem, Communications Manager, Nikon Instruments. "The winning video illustrates how highly sophisticated imaging techniques and systems can help us see and better understand common concepts as well as lead to improvements to technologies and products we all use in our everyday lives."
Second place was awarded to Dr. Richard Kirby, a marine scientist focused on the study of plankton and their environments, for his darkfield video of a phoronid larva of a marine horseshoe worm. Dr. Kirby's subjects can be very hard to capture because of their delicate nature. Despite their importance to many ecosystems, people know relatively little about these creatures, Kirby said. Microscopy, he continued, creates great images that attract the public's curiosity and assist in better understanding of their lives and the role they play in our ecosystems.
Third place went to Mr. James Tandoc for his video of cytoplasmic streaming in onion cells, captured using Differential Interference Contrast (DIC). Tandoc says he hopes to help people learn the differences between animal and plant cells and the function of the different parts of the cell.
The 2020 judging panel included:
- Dr. Dylan Burnette, Assistant Professor of Cell and Developmental Biology at Vanderbilt University
- Dr. Christophe Leterrier, Group Leader at the Institute of Neurophysiopathology at CNRS and Aix-Marseille University
- Samantha Clark, Photo Editor at National Geographic
- Sean Greene, Graphics and Data Journalist at The Los Angeles Times
- Ariel Waldman, Chair of the External Council for NASA's Innovative Advanced Concepts Program
