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. Flat sheet membrane: Fabricated from commercial PVDF polymer. Superhydrophobic. High liquid entry pressure. One-step fabrication of the membrane with online modification of the membrane surface. Modules: Industrial-scale modules available. Customized modular design. Spiral-wound modules. Treatment of high salinity waters from mining, metal treatment, pharmaceutical, chemical synthesis, and oil and gas operations. Achieve zero-liquid discharge (ZLD) in industrial processes. Desalination of seawater or brackish water. Treat brine that is produced as a byproduct of desalination. Membrane distillation (MD) is a membrane technology that uses the vapor pressure gradient across a porous hydrophobic membrane to separate water from other components. MD offers several advantages over other membrane separation processes, including: Lower operating pressures Insensitivity to feed concentration for seawater desalination Almost 100% rejection of solutes Relatively low operating temperatures These advantages have led to promising results in MD processes for zero-liquid discharge, desalination, desalination brine treatment, and many other wastewater treatment applications. However, the commercialization of MD has been constrained by the lack of commercially available high-performance MD membranes and high energy consumption. This work addresses the lack of commercially available high-performance MD membranes and has the potential to be the next workhorse of the water industry. Treatment of difficult streams which is not possible with other conventional methods Usage of waste heat High surface area to volume ratio compared to the plate and frame membrane distillation as the current work is in the spiral-wound configuration Proven method of translating membrane fabrication from lab-scale to industrial-scale phase inversion (PI) casting line Readily available industrial-scale process settings to fabricate membrane of one meter in width and several hundreds of meter in length.

Osteoporosis is a significant global public health concern affecting approximately 500 million people. The condition is associated with high mortality and disability rates due to osteoporotic fractures. The management of osteoporotic fractures comes at a considerable cost of SGD 11K per patient in Singapore, placing a growing burden on healthcare budgets as the aging population increases. Currently, osteoporosis is assessed by measuring bone mineral density (BMD) using dual energy X-ray absorptiometry (DXA). However, the availability of DXA machines, particularly in developing countries, is limited. Consequently, DXA examinations are not routinely ordered, resulting in orthopaedists often lacking DXA results during examinations. Therefore, an alternative method for estimating and screening osteoporosis is necessary. To address this, an automated AI system that can predict a patient's osteoporotic score by evaluating the CTI (cortical thickness index) from a plain femur X-ray scan is designed and developed. This system would provide a preliminary assessment and enable mass screening for osteoporosis. The technology consists of an AI-based software algorithm, to analyse a plain femur X-Ray scan that produces an osteoporosis score, which is equivalent to BMD score produced by DXA machine. The ideal collaboration partners include hospitals and clinics for osteoporosis primary screening, and X-Ray equipment manufacturers to license and translate our invention as an additional feature in their offerings. The proposed automated osteoporotic score prediction technology using AI can be deployed in healthcare industry, e.g. hospitals, medical equipment manufacturers. The technology can be packaged as a cloud-based services, for doctors to use the service for osteoporosis screening from anywhere. It can also be a stand-alone software. The proposed technology is more accessible and less expensive over the traditional method, as it is based on a plain X-ray scan only, which is routinely ordered. The proposed technology is fully automated as it is trained using large amount of data, thus the result is more objective and consistent. The proposed technology can produce osteoporosis score, which is equivalent to BMD score, well-understood by doctors. Infocomm, Artificial Intelligence

Offshore land reclamation has been an important strategy for Singapore to meet its land needs. However, the ultra-soft soil in the surrounding waters makes land reclamation extremely difficult. Besides, many infrastructure projects (i.e., tunnelling, deep excavation, etc.) are also challenging when encountering soft marine clay due to its poor engineering properties, such as high water content, high compressibility, and low shear strength. Currently, ordinary Portland cement (OPC) is the most common binder used for soft clay stabilisation through deep mixing or jet grouting. However, OPC is not very effective for the stabilisation of marine soft clay with high water content. In addition, the production of OPC leads to negative environmental impacts such as non-renewable resources, high energy consumption, and high carbon emissions. The technology owner has developed a sustainable novel binder, entirely from industrial by-products, that has high stabilisation efficiency for marine soft clay. Using the same binder content, the 28-day strength of the novel binder-stabilised soft clay can be 2–3 times higher than that of the OPC-stabilised clay. In addition, the novel binder has a lower cost and less environmental impact, making it an economical and sustainable alternative to OPC. This technology is available for R&D collaboration, IP licensing, and test-bedding with industrial partners in the construction and infrastructure sectors. The features of this technology are: Renewable sources: entirely from industry by-products High strength: the 28-day strength is 2–3 times higher than that of OPC-stabilised soft clay Low permeability: one order of magnitude lower than that of OPC-stabilised soft clay Cost-effective: the total binder cost is 30–40% lower than that of OPC Low energy consumption: about 70% lower than that of OPC production Low carbon emissions: about 90% lower than those of OPC production The novel binder can be used in deep mixing and jet grouting processes for a variety of construction and infrastructure projects to improve the strength and stability of soft clay. The potential applications are as follows: Densification of granular soils Underground tunnelling Support for deep excavations Underpinning of existing foundations Settlement control Liquefaction mitigation The technology offers the following unique features: Extremely high stabilisation efficiency Low binder cost (30–40% lower than OPC) Renewable resources (from industrial by-products) Low energy consumption and CO2 emissions Easy adaptation to existing soil stabilisation processes This technology is available for R&D collaboration, IP licensing, and test-bedding with industrial partners in the construction and infrastructure sectors.

(SGX recommendation for core metrics includes GHG emissions, Energy consumption and Water consumption) Factories and Manufacturing Facilities: Ideal for wastewater management, water-flow and additional IoT sensors may be added to track that the output remains within regulations, or recycled inputs are within specifications. Idle machines can also be switched off, allowing better resource management. Public Institutions: Complements and reinforces water conservation efforts Private Commercial Facilities- provides surveillance for a long-term redesign of water distribution throughout a facility for cost-effectiveness. Housing facilities: Monitor the usage of electricity and water to study possible areas of savings to reduce CO2-Eq. Help to raise general awareness regarding carbon footprint generation. Facilities with unstable power supply or critical processes: With the monitoring and control system, it is possible to control the usage of resources when it is limited or restricted. Power to non-critical equipment may be cut to reduce consumption, and the allocation of fluids may also be set based on different conditions. Compared to existing systems in the market which typically cater to either power or energy monitoring, this solution offers the additional integration of water monitoring as well as additional control features to trigger intervention steps should there be anomalies such as piping leaks. The system allows direct insight to the correlation between what is used to carbon footprint. Data is collected to help users understand the greatest generators of carbon footprint, so that users are more aware, and can consider ways to reduce their carbon equivalent emissions.

All-solid-state lithium-ion batteries (LiBs), also known as the most promising next-generation batteries, have attracted much attention due to their high energy density and safety. The replacement of liquid electrolyte with solid electrolyte could not only improve battery safety and also prolong its lifetime. The most commonly used solid polymer electrolytes (SPEs) are poly(ethylene oxide) (PEO) based, which typically have poor mechanical properties, low ionic conductivity, and a limited oxidation window, thus precluding their use with high-voltage cathodes. Therefore, it is essential to develop cross-linked SPEs with high oxidative stability for high-voltage all-solid-state LiBs in high energy applications. The technology owner has developed a reprocessible cross-linked cationic polytriazolium (PT) based SPE for all-solid-state LiBs. This PT-based SPE is electrochemically stable at voltages >4.0 V, exhibiting a high ionic conductivity below the melting point as well as a high Li+ transference number. In addition to its electrochemical characteristics, this PT-based electrolyte is reprocessible and healable with good flexibility. Such polymeric electrolytes could sustain internal and external stresses during the charging-discharging process, thus prolonging the lifetime of Li-ion batteries while simultaneously tackling safety issues. The technology owner is keen to collaborate with industrial partners such as battery developers and manufacturers for further co-development and test-bedding of solid polymer electrolytes and subsequent licensing of this technology for commercialisation. The technology is a reprocessible cross-linked cationic polytriazolium (PT) based solid polymer electrolyte (SPE) that has the following features: Can be charged to a higher voltage (> 4.0 V), offering stability against high-voltage cathodes Higher energy as compared to commercial polyethylene oxide (PEO) based polymer electrolytes Ionic conductivity is 10-4 S cm-1 at 60 °C, higher than current solid polymer electrolytes (around 10-5 S cm-1 above the melting point > 150 °C) Li+ transference number is around 0.7, higher than current solid polymer electrolytes (around 0.4) Can be reprocessed by pressing at 180 °C This solid polymer electrolyte can be applied to high voltage all-solid-state rechargeable lithium ion batteries, which have the following potential applications: Aerospace and aviation Medical devices Electric vehicles Grid energy storage Consumer electronics IoT devices Electrochemically stability at high voltage (4.2V) Higher ionic conductivity and Li transfer number Simple and efficient one-pot synthesis Reprocessible and healable Enable high-energy-density all-solid-state Li-ion batteries solid polymer electrolyte, energy storage, all solid state, lithium ion battery Materials, Composites, Energy, Battery & SuperCapacitor

Vannamei shrimp culture is often plagued by disease outbreaks. White Spot Syndrome Virus (WSSV) and other pathogens can make shrimp harvest cycles unpredictable.  This technology relates to a comprehensive hybrid biofloc-RAS (recirculatory aquaculture system) shrimp farming system that delivers high yields and mitigates disease. Shrimp post-larvae typically grow faster in biofloc systems and have lower feed conversion ratios (FCRs) for the first 30 days of culture than in clear water recirculation systems. Our technology is cost-effective, scalable, and can be adapted to vertical farming formats. The technology provider is looking for aquaculturist partners who would like to embark on indoor shrimp farming projects. Biofloc technology is an organic approach to shrimp farming. Instead of using costly water purification strategies, sterilization methods, or medicinal applications to eradicate harmful pathogenic agents such as viruses and bacteria, we focus on populating the water microbiota with a community of beneficial microbes, algae, and zooplankton. These beneficial microorganisms outcompete harmful pathogenic agents, remove toxic ammonia, and serve as a food source for shrimp. This technology includes: A proprietary process for inoculating, growing, and maintaining biofloc throughout the duration of shrimp culture, until animals reach a harvest size of 10-20g. A database of the biofloc microbiome obtained via DNA sequencing. A proprietary hybrid biofloc-clearwater RAS system design. Training programs and knowledge transfer opportunities. The biofloc technology has been tested indoors and has achieved successful disease-free survival rates of up to 70-75%. This know-how can also be adapted for use in outdoor commercial shrimp ponds with similar survival rates. In addition to shrimp cultivation, biofloc technology can also be used for fish hatchery/nursery operations for certain fish species, general water treatment operations, and possibly for the cultivation of oyster spats. The global P. vannamei shrimp market is currently worth about USD 30 billion annually. Biofloc shrimp culture can be easily scaled up indoors for super-intensive commercial production in 10-20 ton PVC culture tanks. The average harvest yield is between 4-6 kg/ton of water over a period of 8-10 weeks. This translates to 40-50 tons/hectare in an optimal situation, which is significantly higher than the typical yield of 10-20 tons/hectare for outdoor pond shrimp culture. If PVC culture tanks are stacked vertically, harvest yields can potentially reach >200 tons/hectare. Water expenditure is low because biofloc does not require daily water changes. Water only needs to be topped up to compensate for losses through evaporation. Electricity consumption is also very low because there is no need for high-power water purification equipment or continuous water circulation. In addition to these advantages, biofloc also lowers feed conversion ratio (FCR) and can be easily adopted by existing shrimp farms or land-based fish farming operations. This innovation represents a low-cost, controlled indoor shrimp farming solution that mitigates disease outbreaks. Some of its features are as follows: Low capital expenditure (CAPEX): The initial investment required to set up a biofloc shrimp farm is relatively low. Low operating costs: The day-to-day costs of running a biofloc shrimp farm are also low, as there is no need for expensive water treatment chemicals or additives. No harmful or toxic chemicals/additives: Biofloc shrimp farming is an environmentally friendly approach, as it does not require the use of harmful chemicals or additives. Predictable harvest cycles: Biofloc shrimp farming can produce predictable harvest cycles, as the water quality is tightly controlled. Low or no disease incidents: Biofloc shrimp farming can help to reduce the risk of disease outbreaks, as the water quality is kept optimal. Zero-water exchange: Biofloc shrimp farming does not require the exchange of water, which can save water and reduce the risk of introducing pathogens. Easily scalable indoors: Biofloc shrimp farming can be easily scaled up indoors, making it a viable option for commercial production.
