PolyU study reveals the mechanism of bio-inspired control of liquid flow, enlightening breakthroughs in fluid dynamics and nature-inspired materials technologies

HONG KONG, July 2, 2024 /PRNewswire/ — The more we discover about the natural world, the more we find that nature is the greatest engineer. Past research believed that liquids can only be transported in fixed direction on species with specific liquid communication properties and cannot switch the transport direction. Recently, The Hong Kong Polytechnic University (PolyU) researchers have shown that an African plant controls water movement in a previously unknown way – and this could inspire breakthroughs in a range of technologies in fluid dynamics and nature-inspired materials, including applications that require multistep and repeated reactions, such as microassays, medical diagnosis and solar desalination etc. The study has been recently published in the international academic journal Science.

Liquid transport is an unsung miracle of nature. Tall trees, for example, have to lift huge amounts of water every day from their roots to their highest leaves, which they accomplish in perfect silence. Some lizards and plants channel water through capillaries. In the desert, where making the most of scarce moisture is vital, some beetles can capture fog-borne water and direct it along their backs using a chemical gradient.

Scientists have long sought to hone humankind’s ability to move liquids directionally. Applications as diverse as microfluidics, water harvesting, and heat transfer depend on the efficient directional transport of water, or other fluids, at small or large scales. While the above species provide nature-based inspiration, they are limited to moving liquids in a single direction. A research team led by Prof. WANG Liqiu, Otto Poon Charitable Foundation Professor in Smart and Sustainable Energy, Chair Professor of Thermal-Fluid and Energy Engineering, Department of Mechanical Engineering of PolyU, has discovered that the succulent plant Crassula muscosa, native to Namibia and South Africa, can transport liquid in selected directions.

Together with colleagues from the University of Hong Kong and Shandong University, the PolyU researchers noticed that when two separate shoots of the plant were infused with the same liquids, the liquids were transported in opposite directions. In one case, the liquid travelled exclusively towards the tip, whereas the other shoot directed the flow straight to the plant root. Given the arid but foggy conditions in which C. muscosa lives, the ability to trap water and transport it in selected directions is a lifeline for the plant.

As the shoots were held horizontally, gravity can be ruled out as the cause of the selective direction of transport. Instead, the plant’s special properties stem from the tiny leaves packed onto its shoots. Also known as “fins”, they have a unique profile, with a swept-back body (resembling a shark’s fin) tapering to a narrow ending that points to the tip of the plant. The asymmetry of this shape is the secret to C. muscosa’s selective directional liquid transport. It all has to do with manipulating the meniscus – the curved surface on top of a liquid.

Specifically, the key lies in subtle differences between the fin shapes on different shoots. When the rows of fins bend sharply towards the tip, the liquid on the shoot also flows in that direction. However, on a shoot whose fins – although still pointing at the tip – have a more upward profile, the direction of movement is instead to the root. The flow direction depends on the angles between the shoot body and the two sides of the fin, as these control the forces exerted on droplets by the meniscus – blocking flow in one direction and sending it in the other.

Armed with this understanding of how the plant directs liquid flow, the team created an artificial mimic. Dubbed CMIAs, for ‘C. muscosa-inspired arrays’, these 3D-printed fins act like the tilted leaves of C. muscosa, controlling the orientation of liquid flow. Cleverly, while the fins on a natural plant shoot are immobile, the use of a magnetic material for artificial CMIAs allows them to be reoriented at will. Simply by applying a magnetic field, the liquid flow through a CMIA can be reversed. This opens up the possibility of liquid transport along dynamically changing paths in industrial and laboratory settings. Alternatively, flow could be redirected by changing the spacing between fins.

Numerous areas of technology stand to benefit from CMIAs. Prof. Wang said, “There are foresee applications of real-time directional control of fluid flow in microfluidics, chemical synthesis, and biomedical diagnostics. The biology-mimicking CMIA design could also be used not just for transporting liquids but for mixing them, for example in a T-shaped valve. The method is suited to a range of chemicals and overcomes the heating problem found in some other microfluidic technologies.”

MUMBAI, India, April 20, 2026 /PRNewswire/ — LYKSTAGE, a video-sharing platform owned by LYK Inc., a Delaware-based entity, and founded by New York-based entrepreneur Adris Chakraborty, is redefining how the creator economy works — with a patented monetization model no other platform can legally replicate.

Built by a technology team in India under Manhattan Tech Ventures, LYKSTAGE runs on a patented Watch-Time Monetization Model that fundamentally changes who earns from video content. Creators earn whenever their content’s watch time gets monetized — no subscriber minimums, no waiting periods, and no thresholds to cross before earning begins.

What makes the model unprecedented is that viewers earn too. Logged-in viewers are rewarded whenever their watch time gets monetized — when they watch content uninterrupted and the ad served during viewing is fully consumed. When that happens, the creator earns, the viewer is rewarded, and the platform earns. Every reward is funded by actual ad revenue — not venture capital subsidies. The model is entirely self-sustaining.

The platform serves both skippable and non-skippable ads, determined by an ad server algorithm that optimizes based on viewing patterns and content traction. For advertisers, impressions are served intelligently — matching the right ad format to the right moment, delivering higher completion rates and genuine attention.

LYKSTAGE is now live across five markets — India, the United States, the United Kingdom, Canada, and the UAE — and available on Samsung TV, LG TV, Roku, Apple TV, Android TV, Amazon Fire TV, desktop, mobile web, and native apps on both the App Store and Google Play Store.

Adris Chakraborty, a Kolkata-born Columbia Business School alumnus based in the US since 2003, co-founded Mediamorphosis Advertising & Technology Inc. in New York in 2006 with his spouse and business partner Poulami Mukherjee. The company expanded to the UK in 2012, followed by Manhattan Communications in India — building a multicultural advertising group spanning five countries with over 100 clients, providing LYKSTAGE with built-in advertiser relationships and market intelligence.

The platform has crossed over one million users across all markets, with more than 20,000 creators on board and growing across all five countries — achieved with minimal paid marketing.

LYKSTAGE is a transparent, patented system where the people who create the value are the ones who earn from it.
