Omani researchers develop eco-friendly method to combat bacteria
The study, led by Omani researcher Reem Hilal al Maamari from the UTAS, demonstrates how discarded aluminum foil – typically sent to landfills – can be transformed into high-value nanomaterials using a green synthesis method.
Titled 'Eco-Friendly Synthesis and Characterisation of Aluminum Oxide Nanoparticles from Waste Aluminum Foil for Antibacterial, Anti-fungal and Anti-Corrosion Applications', the research addresses the urgent need to develop sustainable recycling technologies amid rising global aluminum waste.
'These nanoparticles have shown remarkable antibacterial and antifungal properties, opening the door to diverse biological and industrial applications,' the research team stated.
In the healthcare sector, the nanoparticles can be used to manufacture antimicrobial coatings and medical tools, helping reduce the spread of infections in hospitals and clinics. Their anti-corrosion properties make them suitable for protective coatings in the construction and metal industries, particularly in humid or marine environments.
The research also explores their potential use in water purification systems, where the nanoparticles' antimicrobial traits could support clean water access in remote or water-scarce regions. In the food sector, they offer a viable solution for enhancing packaging materials to extend shelf life and prevent microbial contamination.
Agricultural applications include their use as natural antifungal agents to treat soil and seeds, potentially improving crop quality and resistance to disease.
By converting aluminum waste into functional nanomaterials, the project not only offers practical solutions to pressing environmental challenges but also contributes to Oman's sustainability goals and the development of advanced recycling technologies.
The researchers emphasised the need to adopt such technologies to promote environmental stewardship and innovation across multiple sectors, in line with the sultanate's broader vision for a greener and more resilient future.

MTCIT's national space accelerator to boost tech startups in Oman
Muscat – Ministry of Transport, Communications and Information Technology (MTCIT) launched a national initiative – designed to empower local startups to develop innovative space solutions and services – called Space Accelerators Programme on Wednesday. The one-year programme aims to stimulate entrepreneurship in the space sector, attract investment in advanced technologies, and support the localisation and transfer of space services within the sultanate. It also aligns with Oman's broader goals of economic diversification and technological advancement. The programme will be implemented by Omani firm Ankaa Space and Technology Company in partnership with Exotopic, a UK-based firm specialising in accelerator initiatives. It will support ten Omani startups in developing commercially viable space technologies, while enhancing national capabilities in space innovation. Dr Saud bin Humaid al Shuaili, Director General of Policies and Governance and Head of National Space Programme, said the initiative is part of MTCIT's broader efforts to build a vibrant ecosystem for space entrepreneurship. 'The programme offers an integrated environment that combines technical mentorship, entrepreneurial training, and access to a global network of partners and experts,' Shuaili said. It will focus on high-impact sectors including satellite communications, Earth observation, geo-spatial analytics, navigation, artificial intelligence, drones, the Internet of Things, spacecraft simulation, and advanced computing. The top three performing startups will also receive incentives supporting long-term sustainability and growth of their ventures. The programme will include a comprehensive training curriculum covering technical and commercial aspects aimed at enhancing skills of local entrepreneurs.

Oman launches space accelerator programme to boost innovation
MUSCAT: In a significant move in furtherance of Oman Vision 2040, the Sultanate of Oman has launched the Oman Space Accelerators Programme—an innovative programme to foster in-country capabilities in the global space sector and establish a knowledge-based economy. Commissioned by the Ministry of Transport, Communications and Information Technology (MoTCIT), the accelerator is Oman's first and is being established in partnership with Ankaa Space & Technologies and UK space innovation business Exotopic. Dr Ali bin Amer al Shidhani, Under-Secretary for Communications and Information Technology, explained: 'It is the first-of-its-kind accelerator programme in Oman that is initiated to serve technology companies that want to venture into the growing space industry. The programme will provide technical guidance, awareness training, and official networking with investors, global corporations, and world space industry legends.' He continued, "The long-term vision of the accelerator is to equip 10 Omani companies with the necessary tools and expertise to be path-breaking drivers of the space economy, contributing directly to Oman Vision 2040's innovation and human capital targets." The 15-week programme, extending from late August through early December, will support ten Omani startups, small and medium-sized enterprises, entrepreneurs, and academics with a fast-track sequence of training workshops and business development exercises. Dr Saoud bin Humaid al Shoaili, Head of the National Space Programme, linked the programme to broader national interests: "As part of an effort to realize the ambitious goals of the National Space Programme and Oman Vision 2040, we launched a comprehensive strategy aimed at developing strong national capabilities in the sector." Dr Al Shoaili also explained that the project fosters a competitive culture that encourages creative solutions, and the first three entities are awarded to encourage sustainable activities corresponding to strategic goals of the industry. The programme will focus on key space industry domains such as communications, earth observation, geospatial analytics, navigation, drones, AI and machine learning, advanced computing, data storage, IoT, spacecraft simulations, startup acceleration, and technology innovation. He outlined the three strategic pillars of the programme: institutional capacity, individual skills development, and entrepreneurial and commercial capability. 'Since January 2023, we've implemented a number of targeted initiatives to strengthen Omani expertise and readiness in the space domain, in line with national aspirations,' he said. Ghaida al Jabri, Project Manager at Ankaa Space & Technologies, highlighted the inclusive and collaborative nature of the project. "Oman has worked on this programme in partnership with MoTCIT, Al Ankaa, and Exotopic in the National Space Programme. It is a demonstration of direct contribution to the innovation and private sector development pillars of Oman Vision 2040." She added, "The programme aims to fast-track the growth of domestic entities and put them in a position to be at the forefront of Oman's new space economy." Speaking to the Observer, Dan Veal, Principal Investigator at Exotopic, emphasised the strategic timing of Oman's entry into the space race. "Oman is entering the international space sector at a critical time when neighboring nations are heavily investing in space technologies. The project represents a significant opportunity for young Omanis and small and medium enterprises to take up a forward-thinking and fast-growing global industry." He noted, "Given the data-driven nature of the space economy, it's quite open for new entrants to make a significant impact quite soon. Oman has a good chance of competing at the regional and global level."
