Automated Guided Wave Ultrasonic Imaging for Continuous Pipeline Health Monitoring
To ensure safe and cost-effective operations across various industries, it is essential to identify potential pipeline damage early to prevent leaks. This includes monitoring changes in wall thickness to estimate corrosion rates and alerting operators with advanced warning signals about possible corrosion, allowing for rectification before leaks occur. Conventional thickness evaluation processes require manually scanning pipelines using probes, a method that is tedious and challenging, especially in remote locations. Additionally, the high upfront costs (approximately 75%) of traditional non-destructive evaluation (NDE) methods are often incurred before each pipeline thickness measurement. These costs can be even higher if the pipelines are in inaccessible or harsh environments. To address these challenges, an innovative guided wave monitoring system has been developed, which can be permanently installed at critical points along the pipeline network. This system continuously monitors pipeline wall thickness and assesses potential corrosion damage. Compared to other NDE techniques, it accurately measures corrosion rates, sends early warning signals when wall thickness falls below a critical threshold, and significantly reduces the costs associated with setting up measurement equipment in difficult-to-access environments.

High-Performance Boron Absorbents With Flexibility and Minimal Environmental Footprint
Boron is an essential micronutrient necessary for the growth and development of plants, animals, and humans, while also playing a critical role in industries such as manufacturing, agriculture, and semiconductors. However, while beneficial in trace amounts, excessive boron levels can be toxic. High concentrations in drinking water pose significant health risks, particularly to reproductive and developmental systems, while boron contamination in industrial water supplies can degrade process efficiency and product quality. Current methods for boron removal, such as reverse osmosis and ion exchange, face significant limitations. Reverse osmosis struggles to remove boron efficiently, especially in seawater desalination, often requiring multiple stages and high energy consumption to achieve acceptable levels. Ion exchange resins pose low loading capacity and require massive harsh chemicals for regeneration.  The proposed boron absorption technology provides a solution that efficiently removes boron from diverse water sources, including seawater and wastewater. It effectively reduces boron levels to meet stringent standards, such as drinking water limits of less than 0.5 mg/L. The technology aligns with sustainability goals, consuming fewer chemicals and exhibiting strong recovery stability. Additionally, the proposed absorbent is flexible, customizable and compatible with various water treatment applications. The technology owner seeks partnerships to integrate this solution into existing water treatment systems or collaborate on industrial-scale demonstration projects to address boron contamination across multiple sectors.
Oily Wastewater Treatment Technology using High-Performance Oil-Degrading Microorganisms

By decomposing fats and oils directly, it reduces the need for physical separation and incineration, cutting down on industrial waste management costs. This approach also supports sustainable waste reduction and mitigates the risk of clogged sewer pipes. Technology has demonstrated the stable performance of oil decomposition in wastewater throughout a year in a field test at a food oil factory.  The technology owner seeks collaboration with food, oil, and other plants with oily wastewater and wastewater treatment facility providers looking for organic solutions for end users.
Solar Powered Portable Water Purification System
Access to clean and safe drinking water is essential for health, yet millions of people worldwide still lack this necessity. According to the World Health Organization (WHO), over 2 billion people globally use drinking water sources contaminated with feces, leading to severe health consequences. Unsafe water, along with inadequate sanitation and hygiene, is estimated to cause 485,000 diarrheal deaths each year. Water purification technologies face significant challenges, especially in decentralized systems lacking the efficiencies of large-scale operations. They often have a substantial carbon footprint due to energy-intensive processes and reliance on chemicals. Existing portable devices primarily use filtration and have a limited lifetime on-site, with little opportunity for cleaning to restore its performance.  Developed by a research team, this technology effectively addresses the above challenges by employing electrochemical methods that generates strong oxidizing agents to kill micro-organisms present in raw water and potentially degrade organic pollutants that conventional portable reactors cannot remove via filtration. Due to its working mechanism, the device is self-cleaning and does not need regeneration. By harnessing solar energy and activated carbon, this chemical-free purification approach is not only environmentally friendly but also perfectly suited for deployment in remote areas, developing countries, and disaster-stricken zones where traditional water treatment infrastructure is lacking. The technology owner is looking for collaborations with local SMEs to co-develop scaled systems and deploy it through disaster relief organizations, government agencies and non-profit organizations in selected developing countries.

Nature-Inspired Superhydrophobic Membranes for Membrane Distillation
Current state-of-the-art lab-scale methods for fabricating superhydrophobic membranes for membrane distillation often involve complex surface modifications or the use of nanomaterials. However, these methods are difficult to scale up. This technology relates to a pure rheological spray-assisted non-solvent induced phase separation (SANIPS) approach to fabricate superhydrophobic polyvinylidene fluoride (PVDF) membranes. The resulting membranes have high porosity, superhydrophobicity, high liquid entry pressure, and hierarchical micro/nanostructures. They can also be easily scaled up. The spraying step caused local distortion of the membrane surface, which induced a two-stage phase inversion. This led to the formation of multilevel polymeric crystal structures. The morphological structures and other membrane properties (e.g., mechanical strength and liquid entry pressure) could be tuned by applying spraying materials with different physicochemical properties. This facile fabrication method will pave the way for the large-scale production of superhydrophobic membranes for membrane distillation.
