In this collaborative project between Newcastle University and Universiti Malaysia Perlis (UniMAP), the team aimed to create a sustainable, cost-effective lower limb prosthetic socket (LLPS) using natural fiber-reinforced composites. The objectives included designing a green LLPS, assessing its environmental impact, and engaging stakeholders. Pineapple Leaf Fiber (PALF) was chosen for sustainability. The project has also inspired worldwide interest in sustainable LLPS development through a press release, receiving inquiries from students at Nanyang Technological University in Singapore and a group of 7th graders in the USA.

Associate Professor Taweechai Amornsakchai and his team of international researchers have developed novel bio-degradable rigid foams derived from pineapple waste, showcasing impressive properties. Starch and cellulosic materials are key components of the foams, which are processed via microwave gel formation and filler blending. The foams feature high strength, and rapid biodegradation, with potential for practical use from packaging, to construction, automotive, and aerospace.

A team of scientists from Thailand and Malaysia, led by principal investigator, Associate Professor Taweechai Amornsakchai from Mahidol University, has successfully developed a low-cost and green method to make films prepared from pineapple stem starch for food packaging, such as fruits and vegetable.

A team of researchers from Singapore and the UK, led by Dr Wei Liang Lai, with supervisor, Associate Professor Kheng Lim Goh, has developed a portable device for repairing hard-to-see damage in carbon fiber materials. The device has great potential for the aerospace industry, such as to repair the fuselage of commercial aircraft.

An international team of researchers from India and Singapore, led by Associate Professor Kheng Lim Goh from Newcastle University in Singpaore, has examined the impact of plastic waste management on creating a new type of clean-energy device, Tribo-electric nanogenerator. It compares recycling practices in Singapore and India, highlighting the importance of waste policies and infrastructure for successful recycling of plastics for making the clean-energy device. Challenges include contamination and decreased material quality with recycling.

A group of researchers from universities in Thailand and Malaysia have collaborated to develop a unique kind of film that is good for the environment and can decompose naturally. They made this film using leftover pineapple stems, which helps reduce the use of harmful plastic films. This new film has the potential to be used as packaging material, contributing to a more sustainable way of doing business and promoting a circular economy.

Synthetic hydrogels were shown to provide an effective scaffold for neuronal tissue growth in areas of brain damage, providing a possible approach for brain tissue reconstruction.

An international team of researchers from India and Singapore has successfully developed a novel coating with enhanced water repellent properties using natural material from the waste crab shell.

Scientists demonstrate an optical trapping technique using nanotextured black silicon that can efficiently trap polymer chains. By adjusting the laser intensity, these “optical tweezers” can control the florescence color emitted through a local concentration of a perylene-modified polymer solution. From a low intensity blue to high intensity orange, this reversible and fully remote technology can almost reach the entire RGB spectrum.

Spontaneous wide-area spreading of oil on water inspires a facile energy-saving route of crafting electrically conductive nanostructures for future sensor/energy devices

Using a CeO2 catalyst, researchers develop an effective catalytic process for the direct synthesis of polycarbonate diols without the need for dehydrating agents. The high yield, high selective process has CO2 blown at atmospheric pressure to evaporate excess water by-product allowing for a catalytic process that can be used with any substrate with a boiling point higher than water.

Scientists develop degradation-mitigating additives that vastly extend the lifespan of Nafion-based fuel cells

An inexpensive hydrogel-based material efficiently captures moisture even from low-humidity air and then releases it on demand.

Conjugated polymers designed with a twist produce tiny, brightly fluorescent particles with broad applications.
