• Longer lasting de-icer cuts environmental impact of airports in winter

    When temperatures drop below zero, aircraft need to be doused with thousands of litres of de-icing fluids to keep them functioning. But when the plane takes off, most of the liquid has flowed off and ends up polluting freshwater streams and lakes. University of Illinois Chicago (UIC) researchers have developed an extensive family of more than 80 anti-freezing coatings, which can be easily applied to aluminium, steel, copper, glass, plastic or any industrial surface without preconditioning or expensive surface treatments. “We questioned the lifetime of the cryoprotectants and looked at new ways to increase their effectivity,” said researcher Sushant Anand. “Glycols dissolve very fast in the water and get washed away before the plane takes off, and it’s a serious problem that costs hundreds…

  • ‘Phenomenal’ live view of nesting eagles captured via camera hidden in stick

    White-tailed eagles Shona and Finn, also known as sea eagles, are incubating two eggs at their nest in the Cairngorms. A camera has been installed in a stick around three metres away from the nest and the birds’ activities are being beamed live to the Loch Garten Nature Centre at RSPB Scotland’s nature reserve at Abernethy. As eagles will often become nervous about new items or changes around their nest, all work was undertaken in autumn when it was safe to do so and the camera has been hidden in a stick to avoid unsettling them. Jess Tomes, Abernethy site manager for people at RSPB Scotland, said: “This is an enormously exciting addition to the visitor offer at the Loch Garten Nature Centre. The images we’re getting live from the nest are phenomenal and our visitors will get a very rare…

  • Diabetes patients trial ‘artificial pancreas’ on the NHS

    The device reads the patient's blood sugar levels and uses an algorithm to determine the amount of insulin that should be administered to keep the level steady. According to its developers, the technology is much more effective at managing blood sugar levels than current devices and requires far less input than at present. “Having machines monitor and deliver medication for diabetes patients sounds quite sci-fi-like, but when you think of it, technology and machines are part and parcel of how we live our lives every day,” said Professor Partha Kar, NHS national speciality adviser for diabetes. He explained the device picks up the patient’s glucose levels via a sensor under the skin, sends the reading across to a delivery system – the pump – and then the system kicks in to assess how much…

  • View from India: When design is democratised

    To put things in perspective, the desktop economy progressed into laptops and tablets, later the mobile and then the metaverse, whose thrust is on virtual 3D platforms. Understandably, product design has evolved at every stage. Design was an elaborate process in the desktop economy. Designers spent two to three months on the design that went through the beta phase before being piloted and then rolled out commercially. This was also the case with appliances such as washing machines that were designed two decades ago. The design perspective is different in the present scenario, and Alexa could be an example of that. Alexa works on voice command. The product is talking to the user. As a result, Alexa will have data about a particular user’s preferences. Being personalised in nature, improvisation…

  • RRS Sir David Attenborough completes ‘ice trials’ in Antarctica

    The trials saw the polar research ship tested through the ice at every power level to measure its performance against expectations. The vessel’s captain, Ralph Stevens, said that team was “really pleased” with its performance. Stevens and his team also performed a range of manoeuvres, including reversing, turning, and impact tests going into the ice at different speeds, in icy areas of the sea around the Antarctic Peninsula and Bellinghausen Sea. The British Antarctic Survey (BAS), which operates the RRS Sir David Attenborough, said  satellite data was used to locate suitable areas of ice for the trials. According to the team, most manoeuvres were in fast ice, which is attached to the coast and not moving, allowing them to work out accurately the amount of energy needed to break the ice…

  • Sponsored: The new era of technical conferences has landed – UKEmbedded

    The UK embedded event calendar has changed dramatically in the last decade. There are fewer large “expo” style events and many smaller one-day technical conferences.

Content rich agenda The day will deliver a balanced agenda covering many of the key areas affecting the embedded space at the…

  • UK greenhouse gas emissions rose 5 per cent in 2021

    However, the provisional data for 2021 reveals that climate pollution remained more than 5 per cent below 2019 levels, reflecting the ongoing impact of Covid-19 restrictions. Total greenhouse gas emissions were up 4.7 per cent in 2021 on 2020 levels, reaching 424.5 million tonnes, but were 5.2 per cent lower than 2019. Pollution from key greenhouse gas carbon dioxide was up 6.3 per cent year-on-year, with increases in all sectors, led by a 10 per cent jump in transport emissions, the statistics from the Business Department (Beis) show. Looking over the long term, greenhouse gas emissions in 2021 were 47 per cent below what they were in 1990. The biggest driver of the long-term fall in emissions is a decrease in pollution from power stations, as electricity generation shifts away from…

  • Plastic packaging tax could increase plastic exports warn experts

    E&T has also heard concerns that the tax will not be paid back into the UK’s recycling system, with retailers warning that the added costs could be passed on to consumers, exacerbating the cost-of-living crisis. From 1 April, businesses manufacturing or importing ten tonnes or more a year of plastic packaging that contains less than 30 per cent recycled plastic will be taxed at £200 per tonne. Big supermarkets and other retailers that produce and sell own-brand products will need to pay the tax. Imports of packaging which already contains goods, such as plastic bottles filled with drinks or plastic packaging around goods, will also be subject to the tax. In Europe, the EU Commission has already introduced a plastic packaging levy on Member States at a rate of €800/tonne based on the amount…

It has supported research into the first feasibility…

  • Oil prices fall as US considers record reserves release

    The price of Brent crude – the most used way of measuring the UK’s oil price – fell by nearly $4 (£3.05) to $109.21 (£83.21) a barrel on reports that President Joe Biden is considering releasing up to 180 million barrels from the US Strategic Petroleum Reserve. This would be the biggest release since they created the reserve in 1974. News outlets expect Biden to announce his administration’s latest measures to address soaring fuel prices later today (31 March). “Desperate times, clearly call for desperate measures and clearly the Biden administration believes the spike in oil prices warrants this move to eat into the country’s emergency supplies,” said Susannah Streeter, senior investment and markets analyst at Hargreaves Lansdown. “A drip release of one million barrels of oil is on the…

  • Safety fears emerge over government’s EV charging strategy

    While the ECA said it broadly welcomed the strategy, published last week, it warned that the government’s focus on “market-led” strategy and lack of joined-up policy could “encourage a race-to-the-bottom approach”. Andrew Eldred, the ECA’s director of workforce and public affairs, said: “Safe, high-quality electrical work needs to be done by electrically competent people. We know for a fact that our industry is ready to rise to the challenge of Net Zero, but a purely ‘market-led’ policy can lead to a race to the bottom on cost and a drop in quality follows. “This will inevitably compromise the efficiency and safety of what gets installed.” Eldred's comments come just days after Electrical Safety First - a charity dedicated to reducing fires, deaths and injuries arising from electricity…

  • Nearly 40 per cent of UK businesses hit by cyber attacks

    The ' Cyber Security Breaches Survey 2022 ' revealed that the most common threat vector was phishing attempts, reported by 83 per cent of businesses. The annual survey is intended to be a useful research study for UK cyber resilience, aligning with the National Cyber Strategy. It is primarily used to inform government policy on cyber security, making the UK cyber space a secure place to do business. The study explores the policies, processes and approaches to cyber security for businesses, charities and educational institutions. It also considers the different cyber attacks these organisations face, as well as how these organisations are impacted and respond. While the 39 per cent of UK businesses which identified a cyber attack is a consistent figure with recent years, the survey also…

Other focus areas include low-emissions technologies and new power electronics applications, as well as…

  • EV makers race to find workaround as supply shortages bite

    Following Russia’s invasion of Ukraine, the race is on for electric vehicle manufacturers, OEMs and their suppliers to find a solution to the critical supply shortages that are already impeding the production of battery-electric vehicles in Europe and the US. Car makers and EV platforms are desperate to establish alternative sources of supply for some components, which would typically come from production plants in Ukraine. Makers of EV batteries and semiconductors are also vying for supplies of vital raw materials, such as palladium and nickel, as well as noble gases such as neon, which are typically sourced from Russia and Ukraine. About half of the world’s supply of semiconductor-grade neon is sourced from two Ukrainian companies, Ingas and Cryoin. The gas is a by-product of the separation…

  • Committee challenges police use of AI

    The Lords Justice and Home Affairs committee said new technologies were being created in a “new Wild West” without the law and public awareness keeping up with developments, warning that the lack of oversight meant “users are in effect making it up as they go along”. The cross-party group added that while AI has the potential to improve people’s lives, it could have “serious implications” for human rights and civil liberties in the justice system. “Algorithms are being used to improve crime detection, aid the security categorisation of prisoners, streamline entry clearance processes at our borders and generate new insights that feed into the entire criminal justice pipeline,” the peers said. The committee added that scrutiny was not ensuring new tools were “safe, necessary, proportionate…

  • Petition calling for 40 per cent cut in fuel duty hits 100,000 signatures

    The petition calls for fuel duty and VAT on fuel to be slashed by 40 per cent for two years. Fuel retailers have been accused of failing to fully pass on the 5p per litre cut in fuel duty introduced by Chancellor Rishi Sunak in last week's Spring Statement. In theory, that cut represented a saving of 6p per litre because of its impact on VAT. However, the average price of a litre of petrol at UK forecourts has fallen by just 3.8p per litre. Figures from data firm Experian Catalist show the average price per litre on Tuesday was 163.5p, compared with 167.3p on 22 March. The average price of diesel fell by 2.2p per litre over the same period, from 179.7p to 177.5p. Rod Dennis, RAC fuel spokesman, said: “If the Treasury wasn’t aware of the strength of feeling when it comes to fuel prices…

  • Dyson unveils headphones with air-purifying mask

    Known as the Dyson Zone, the wearable device combines noise-cancelling over-ear headphones with a visor that sits in front of the nose and mouth that delivers filtered air. The air-purifying headphones result from over a decade of air-quality research and development and were designed to tackle the urban issues of air quality and noise pollution. “Air pollution is a global problem – it affects us everywhere we go. In our homes, at school, at work, and as we travel, whether on foot, on a bike, or by public or private transport,” said chief engineer Jake Dyson. “The Dyson Zone purifies the air you breathe on the move.” Jake Dyson unveils the new Dyson Zone air-purifying headphones in London.

  • Cement industry takes next step on path to net zero

    Egypt, which will host the COP27 2022 UN Climate Change Conference later this year, is among the initial group of countries leading an international initiative to decarbonise the global cement and concrete industries. It joins India, Thailand and Colombia in the first wave of a series of Net Zero Accelerator projects announced by the Global Cement and Concrete Association today as part of plans to achieves targets established by its 2050 Net Zero Global Industry Roadmap. The four countries together represent approximately 10 per cent of the world’s cement and concrete production. Globally, cement and concrete manufacture accounts for around 7 per cent of carbon dioxide emissions. The GCCA roadmap, which was claimed to mark the biggest international commitment by a heavy industry to decarbonise…

  • ‘Paradigm change’ needed for forecasting corrosion damage of bridges

    A group of researchers from Switzerland, the US, Canada and Norway have said the most common cause of degradation and failures of reinforced concrete structures is chloride-induced corrosion of embedded steel elements. They warned that the issue is a “pervasive, urgent problem” that requires more attention and public awareness. An underlying concept of a chloride threshold is widely used, and all existing models to forecast corrosion performance of reinforced concrete structures exposed to chloride environments are based on this one common theoretical concept. But the researchers believe change is needed to address the growing challenges of ageing structures losing functionality and potentially collapsing, as well as their associated greenhouse gas emissions. “Corrosion of steel within…

  • IT body raises concerns over campaign to limit end-to-end encryption

    Facebook has previously announced plans to roll out end-to-end encryption across its messaging services. However, a recent campaign backed by the Government warned against a wider tech industry rollout. Critics of the technology have asked firms to find a way of allowing law-enforcement agencies to access communications while still protecting privacy, warning that otherwise the public, and particularly children, could be at greater risk of being exposed to worrying content and online predators. But in a survey carried out by IT professional body the BCS, 78 per cent of industry professionals said they did not believe restricting the use of such encryption in messaging would protect users. The research also found a further 66 per cent of specialists said restricting such encryption would…

  • BT halts removal of landline phones following customer backlash

    BT, among other telecoms companies, had pledged to equip all homes with digital voice-over-internet phones by 2025 as part of a much needed update to the UK’s communication infrastructure. The controversial rollout, which saw copper landlines removed in favour of fibre-optic cables, have resulted in some customers being unable to call 999 when their power has gone out as a result of storms cutting off their internet access. BT’s chief executive of consumer brands Marc Allera apologised and said the firm had “underestimated the disruptive impact this upgrade would have.” He added that “in hindsight” the company had rolled the technology out “too early”. Allera added that the disruption caused by recent Storms Arwen and Eunice brought these issues into sharper focus when people – including…

  • Book review: ‘The Joy of Science’ by Jim Al-Khalili

    “When you haven’t been properly introduced to a subject, it can seem downright forbidding,” says Jim Al-Khalili in the preface to his slender volume that sets out to explain to those who haven’t yet read the memo just why science is not only crucial but one of life’s great pleasures. While the poet Keats thought that Newton had destroyed the rainbow by explaining how prisms work, the theoretical physicist Al-Khalili goes into raptures about refraction. And it’s a good place to start a primer on how to think scientifically – plenty of other writers have started here too – because, if nothing else, rainbows aren’t forbidding. Although entitled ‘The Joy of Science’ (Princeton University Press, £12.99, ISBN 9780691211572), this book might just as easily have been called the gentle philosophy…

  • Towards a circular economy in lighting

    As a global society, we are incredibly and unsustainably wasteful. According to a recent WWF report , we use 1.8 times the volume of resources that our planet can sustain. Another study from the World Economic Forum estimates that one truckload of plastic is dumped into our oceans every minute. If we continue at the current rate, this is expected to increase to two per minute by 2030, and four per minute by 2050. As the world continues to overuse its limited resources, increasingly scarce materials will become more expensive and challenging to source. We owe it to our customers and the world to do better. The only way to do this is to create a model of manufacturing products with minimal waste that can be upgraded, serviced, reused, refurbished, or recycled and support saving energy. At…

  • National Grid to sell 60 per cent of its gas business

    The deal was first announced in March 2021 and forms part of National Grid’s shift towards investing more into its electricity business following last year’s acquisition of Western Power Distribution (WPD). The Competition and Markets Authority (CMA) gave the green light for the £7.8bn takeover of WPD in September after an investigation over the deal’s potential impact on the market. Once the sale of its gas business has gone through, National Grid will receive approximately £2.2bn in cash and will continue to own a 40 per cent minority equity interest. It will also receive approximately £2bn from additional debt financing at completion. Like the WPD purchase, completion of the sale will be subject to certain antitrust and regulatory conditions, but National Grid said it expects the transaction…
