PolyU researchers develop breakthrough method for self-stimulated ejection of freezing droplets, unlocking cost-effective applications in de-icing
Published in Nature Chemical Engineering as the cover feature for its last December issue, the research project “Freezing droplet ejection by spring-like elastic pillars” is led by Prof. Zuankai WANG, Associate Vice President (Research and Innovation), Kuok Group Professor in Nature-Inspired Engineering and Chair Professor of the PolyU Department of Mechanical Engineering, and Prof. Haimin YAO, Associate Professor of the PolyU Department of Mechanical Engineering. First co-authors include Postdoctoral Fellow Dr Huanhuan ZHANG, PhD student Mr Wei ZHANG, Research Assistant Professor Dr Yuankai JIN, and PhD student Mr Chenyang WU.
The discovery of the self-ejection phenomenon in freezing droplets was inspired by a fungus capable of shooting its spores away through osmosis-induced volume expansion. Noting that a similar volume expansion occurs when water droplet is freezing, the research team has replicated the self-shooting mechanism found in the fungi and developed a structured elastic surface (SES) with spring-like pillars and wetting contrast that allows for the spontaneous ejection of freezing water droplets.
The SES structure is designed to accelerate the ejection velocity and enlarge the kinetic energy transformation of freezing droplets. When the freezing droplet undergoes volume expansion, it compresses the pillar of SES. The volume expansion work is first converted to and stored as elastic energy in the pillar within tens of seconds, and then to be transformed into the droplet’s kinetic energy rapidly within milliseconds. This thousandfold reduction in timescales leads to sufficient kinetic energy to drive freezing droplet ejection.
The simple SES structure, after parameter design, is effective in ejecting freezing droplets without external energy input and even against the forces of wind and gravity. It can be applied to aircraft, wind blades or cable lines to prevent hazards caused by ice accretion. Dr Huanhuan Zhang said, “It is exciting that we, for the first time, introduce a self-powered ice removal concept that will offer a wide range of innovative solutions. We will continuously improve the design of SES, allowing it to be manufactured at various scales and at a low cost to meet societal needs.”
Furthermore, the theoretical model developed in the research elucidates the factors determining the successful onset of the freezing droplet ejection phenomenon, with scalable design exhibiting potential practicability in various fields.
Prof. Wang envisions, “This nature-inspired research paved the way for numerous impactful applications. We believe that the freezing droplet ejection, as a prototype, could stimulate the development of self-powered concepts and methods for a wide range of purposes such as de-icing, energy harvesting and soft robotic applications.”
Specifically, droplet ejection induced by volume expansion enhances understanding of multi-phase freezing dynamics for anti-icing applications. Prof. Yao remarked, “Our research demonstrates a strategy to efficiently harness and utilise the volume expansion work of freezing droplets to generate ballistic motion. This could subsequently expand the application of energy conversion phenomena, and inspire the development of droplet-based energy generators and soft robotic catapults.”

The Taiwan-born pet mobility brand opens its first SoHo pop-up inside Flying Solo, bringing its Nordic-designed pet stroller collection to the heart of New York City.
NEW YORK, USA – Media OutReach Newswire – 02 April 2026 – FikaGO, the design-led pet mobility brand recognized across Asia and Europe, has opened its first New York City pop-up store inside Flying Solo in SoHo. The opening marks a deliberate move for a pet brand into one of the world’s most competitive retail districts.
Since entering the online American market in 2025, FikaGO has built a growing community of pet parents who see their animals as a central part of everyday life. Positioned as lifestyle essentials rather than conventional pet gear, FikaGO’s range of products is designed for people who want the best for their fur babies.
“We’ve always believed that pet products should not only be functional, but also beautifully integrated into everyday life.” — Eric Guu, Co-founder, FikaGO
SoHo was a considered choice: Flying Solo, with locations in New York and Paris, is known for championing independent design with a distinctly global sensibility.
The pop-up showcases FikaGO’s auto-folding Free To Go 2 in Sandy Beige, the brand’s bestselling product. All FikaGO’s products are manufactured using eco-friendly fabrics made from recycled materials, reflecting a commitment to sustainability. This includes their large-capacity Agile 2 pet strollers to their airline-approved Truffle carriers and the heavy-duty Kross pet wagon.
“Launching in SoHo is a meaningful milestone for us; it allows customers to truly experience the quality, design, and intention behind every FikaGO product.” — Eric Guu, Co-founder, FikaGO
As pet ownership rises globally, particularly among urban millennials and Gen Zs, demand for products that combine functionality, design, and lifestyle integration continues to grow. FikaGO was built for precisely this moment, and SoHo is precisely where that moment lives.
Visit the FikaGO pop-up at Flying Solo, 419 Broome Street, New York, or explore the full collection at https://us.fikago.com/.

Lee Kum Kee Celebrates Culinary Excellence at the Historic Hong Kong Debut of Asia’s 50 Best Restaurants 2026
From 23-25 March, Lee Kum Kee brought together top chefs, diverse cultures and industry communities through a range of thoughtfully curated experiences, bringing authentic Asian flavours to the global stage. As well as reaffirming the brand’s Asian roots and international perspective, its involvement reflected an enduring commitment to preserving culinary heritage and driving gastronomic innovation.
“Asian Flavour Duet“: A Culinary Journey Through Heritage and Innovation
Helping to build momentums for this year’s awards, Lee Kum Kee collaborated with Vicky Cheng, the acclaimed Executive Chef and owner of WING, to co-create the “Asian Flavour Duet”, a Hong Kong-style late-night supper party on 24 March. Hosted at two Hong Kong culinary landmarks, the experience unfolded in two chapters – “Paying Tribute to Heritage” and “Innovative Fusion” – and invited guests to explore the limitless possibilities of Asian flavour.
The evening began at the century-old Lin Heung Lau teahouse, a space filled with nostalgia and memories for generations of Hong Kongers. Chef Vicky reinterpreted classic Hong Kong late-night dishes using signature Lee Kum Kee sauces, while guests were immersed in the warmth of the historic venue.
The celebration then moved to Medora, Chef Vicky’s Western dining space, where an “Innovative Fusion” was revealed. He showcased his modern culinary philosophy by incorporating Lee Kum Kee sauces with contemporary techniques to create bold, unexpected dishes. Guests also enjoyed specially crafted cocktails infused with Lee Kum Kee sauces, alongside a delightful yet refined sauce-inspired gelato, demonstrating a harmonious interweaving of savoury, umami, sweetness and spice.
