• Joint research project will combine effort and expertise of pavement engineers, material scientists and computational fluid dynamics experts

• Project to look at improving quality, longevity and accessibility of the highway network

• Aston University will be working with University of Nottingham and seven other industrial partners including Highways England and the Road Surface Treatment Association



A project which will be the driving force behind the redesigning of roads and changes in road repairs could revolutionise the way potholes are repaired, and road surfaces are designed.

The three-year collaboration, ‘Prevention and Management of Road Surface Damage’, is being led by Mujib Rahman, professor in civil engineering, Department of Civil Engineering at Aston University and Dr Nick Thom of the University of Nottingham.

The project will combine the efforts and expertise of pavement engineers, material scientists and computational fluid dynamic experts from both universities.

The research aims to improve the design and construction of roads to minimise surface damage caused by water freezing and thawing, and general wear and tear from traffic. It also will be looking at how to change the science behind road repairs and maintenance.

Research will be looking at two main elements:


- Enable the design of roads to prevent surface damage from water and environmental factors

- Introduce a change in the management of road repair and create a more durable repair of the road surface.

.

Professor Rahman said that smoother roads were critical to the nation as the 250,000 miles of paved road, valued at £750 billion, which is the network for deliveries of goods and services across the UK.

But he added potholes and damage to roads had become ‘increasingly problematic’ for all users.

“We want to drive out the pothole epidemic that has overcome the UK in recent years. Due to record breaking rainfall, extreme cold weather and tight financial constraints on highway authorities, this situation has become much worse. This has been combined with the lack of longevity in some repairs” he said.


Dr Nick Thom, from the Nottingham Transportation Engineering Centre Research Group, said: “The expected deliverables are material specifications and maintenance guidelines designed – like a Covid vaccine – to stop this disease of the road in its tracks. In the main this will be about doing better with currently-used resources, but, given the expected slump in future oil production with consequent loss of bitumen supplies, the search will also be on for alternative viable high-performance products.”

The project has been funded by Engineering and Physical Science Research Council (EPSRC) and will be running until March 2024. Supporting it will also be ADEPT, Highways England, Transport for London, Nottinghamshire County Council, Cooper Technology and the Road Surface Treatment Association (RSTA).

Aston University and Birmingham Women and Children’s Hospital developing new devices to improve drug treatment safety

The new device is designed to reduce the risk of injuries when medicines being delivered into a vein enter the surrounding tissues It detects this problem at the earliest stages, before it is visible to the human eye The project is being supported by SPARK The Midlands at Aston University, a network to support technology development for unmet clinical needs. Clinicians at Birmingham Women’s and Children's NHS Foundation Trust (BWC) have joined with academics at Aston University to create an innovative sensor to reduce the risk of injuries caused when drugs being delivered into a vein enter the surrounding tissue. This complication, called extravasation, can cause harm and, in the most severe cases, life-changing injuries and permanent scarring. It happens most often when infusing medicines into peripheral intravenous (IV) devices, such as a cannula, but can also occur when infusing into a central venous access device. By joining together, BWC and Aston University are combining clinical, academic and engineering expertise to create a sensor that can detect extravasation at its earliest stages. Karl Emms, lead nurse for patient safety at BWC, said: “We've done lots of work across our Trust that has successfully reduced incidents. While we've made fantastic progress, there is only so much we can do as early signs of extravasation can be difficult to detect with the human eye. “The next step is to develop a technology that can do what people can't - detection as it happens. This will make a huge impact on outcomes as the faster we can detect extravasation, the less likely it is that it will cause serious harm.” The focused work to date addressing the issue has recently been recognised by the Nursing Times Awards 2024, winning the Patient Safety Improvement title for this year. This new project is supported by SPARK The Midlands, a network at Aston University dedicated to providing academic support to advance healthcare research discoveries in the region. SPARK The Midlands is the first UK branch of Stanford University's prestigious global SPARK programme. It comes as a result of Aston University’s active involvement in the delivery of the West Midlands Health Tech Innovation Accelerator (WMHTIA) – a government-funded project aimed at helping companies drive their innovations towards market success. The SPARK scheme helps to provide mentorship and forge networks between researchers, those with technical and specialist knowledge and potential sources of funding. SPARK members have access to workshops led by industry experts, covering topics such as medical device regulations, establishing good clinical trials, and creating an enticing target product profile to engage future funders. Luke Southan, head of research commercialisation at Aston University and SPARK UK director, said: “I was blown away when Karl first brought this idea to me. I knew we had to do everything we could to make this a reality. This project has the potential to transform the standard of care for a genuine clinical need, which is what SPARK is all about.” Work on another potentially transformative project has also begun as the team are working to develop a medical device that detects the position of a nasogastric feeding tube. There is a risk of serious harm and danger to life if nasogastric tubes move into the lungs, rather than the stomach, and feed is passed through them. Emms explained: “pH test strips can usually detect nasogastric tube misplacement, but some children undergoing treatment can have altered pH levels in the stomach. This means this test sometimes does not work. “A medical device that can detect misplacement can potentially stop harm and fatalities caused by these incidents.” SPARK will bring together engineers, academics and clinicians for both projects to develop the devices for clinical trial, with a goal of the technologies being ready for clinical use in three to five years. Southan said: “BWC is one of our first partners at SPARK and we're really excited to work with them to make a vital impact on paediatric healthcare in the Midlands and beyond."

Aston University researcher develops new optical technique that could revolutionise medical diagnostics

New light technique could revolutionise non-invasive medical diagnostics Orbital Angular Momentum could be harnessed to improve imaging and data transmission through biological tissues Could eventually have potential to make procedures such as surgery or biopsies unnecessary. An Aston University researcher has developed a new technique using light which could revolutionise non-invasive medical diagnostics and optical communication. The research showcases how a type of light called the Orbital Angular Momentum (OAM) can be harnessed to improve imaging and data transmission through skin and other biological tissues. A team led by Professor Igor Meglinski found that OAM light has unmatched sensitivity and accuracy that could result in making procedures such as surgery or biopsies unnecessary. In addition it could enable doctors to track the progression of diseases and plan appropriate treatment options. OAM is defined as a type of structured light beams, which are light fields which have a tailored spatial structure. Often referred to as vortex beams, they have previously been applied to a number of developments in different applications including astronomy, microscopy, imaging, metrology, sensing, and optical communications. Professor Meglinski in collaboration with researchers from the University of Oulu, Finland conducted the research which is detailed in the paper “Phase preservation of orbital angular momentum of light in multiple scattering environment” which is published in the Nature journal Light Science & Application. The paper has since been named as one of the year’s most exciting pieces of research by international optics and photonics membership organisation, Optica. The study reveals that OAM retains its phase characteristics even when passing through highly scattering media, unlike regular light signals. This means it can detect extremely small changes with an accuracy of up to 0.000001 on the refractive index, far surpassing the capabilities of many current diagnostic technologies. Professor Meglinski who is based at Aston Institute of Photonic Technologies said: “By showing that OAM light can travel through turbid or cloudy and scattering media, the study opens up new possibilities for advanced biomedical applications. “For example, this technology could lead to more accurate and non-invasive ways to monitor blood glucose levels, providing an easier and less painful method for people with diabetes.” The research team conducted a series of controlled experiments, transmitting OAM beams through media with varying levels of turbidity and refractive indices. They used advanced detection techniques, including interferometry and digital holography, to capture and analyse the light's behaviour. They found that the consistency between experimental results and theoretical models highlighted the ability of the OAM-based approach. The researchers believe that their study’s findings pave the way for a range of transformative applications. By adjusting the initial phase of OAM light, they believe that revolutionary advancements in fields such as secure optical communication systems and advanced biomedical imaging will be possible in the future. Professor Meglinski added: "The potential for precise, non-invasive transcutaneous glucose monitoring represents a significant leap forward in medical diagnostics. “My team’s methodological framework and experimental validations provide a comprehensive understanding of how OAM light interacts with complex scattering environments, reinforcing its potential as a versatile technology for future optical sensing and imaging challenges.” ENDS https://www.nature.com/articles/s41377-024-01562-7 Light: Science & Applications volume 13, Article number: 214 (2024) August 2024 https://doi.org/10.1038/s41377-024-01562-7 Authors: Igor Meglinski, Ivan Lopushenko, Anton Sdobnov & Alexander Bykov About Aston University For over a century, Aston University’s enduring purpose has been to make our world a better place through education, research and innovation, by enabling our students to succeed in work and life, and by supporting our communities to thrive economically, socially and culturally.

Aston University researchers to explore using AI and fibre-optic networks to monitor natural hazards and infrastructures

Aston University is leading a new £5.5 million EU research project Will focus on converting fibre-optic cables into sensors to detect natural hazards Could identify earthquakes and tsunamis and assess civil infrastructure. Aston University is leading a new £5.5 million EU research project to explore converting existing telecommunication fibre-optic cables into sensors which can detect natural hazards, such as earthquakes and tsunamis, and assess the condition of civil infrastructure. The project is called ECSTATIC (Engineering Combined Sensing and Telecommunications Architectures for Tectonic and Infrastructure Characterisation) and is part of the Horizon Europe Research and Innovation Action (RIA), which aims to tackle global challenges and boost the continent’s industrial competitiveness. Converting telecom fibres into sensors requires new digital signal processing to overcome the limited data storage and processing capabilities of existing communication networks. To address this the project will use localised, high performance digital processing that will integrate artificial intelligence and machine learning. The researchers’ goal is to minimise algorithms’ complexity while providing extremely accurate real-time sensing of events and network condition. The new laser interrogation and signal processing technologies will be tested using existing fibre optic networks, including those underwater, in cities, and along railway infrastructure to assess their potential. Delivered by a consortium of 14 partners across seven countries, from academic and non-academic sectors, the research will start in February 2025 and will last three and a half years. The Europe-wide team will be led by Professor David Webb who is based in the Aston Institute of Photonic Technologies (AIPT). Professor Webb said: “There are more than five billion kilometres of installed data communications optical fibre cable, which provides an opportunity to create a globe-spanning network of fibre sensors, without laying any new fibres. “These traverse the seas and oceans - where conventional sensors are practically non-existent - and major infrastructures, offering the potential for smart structural health monitoring.” Professor Webb will be joined by fellow researchers Professor Sergei Turitsyn, Dr Haris Alexakis and Dr Pedro Freire.
