Bringing the green revolution to electronics

From biomemory to implants, researchers are looking for ways to make more eco-friendly electronic components. Researchers are investigating how to make electronic components from eco-friendly, biodegradable materials to help address a growing public health and environmental problem: around 50 million tonnes of electronic waste are produced every year. Less than 20% of the e-waste we produce is formally recycled. Much of the rest ends up in landfills, contaminating soil and groundwater, or is informally recycled, exposing workers to hazardous substances like mercury, lead and cadmium. Improper e-waste management also leads to a significant loss of scarce and valuable raw materials, like gold, platinum and cobalt. According to a UN report, there is 100 times more gold in a tonne of e-waste than in a tonne of gold ore. While natural biomaterials are flexible, cheap and biocompatible, they do not conduct an electric current very well. Researchers are exploring combinations with other materials to form viable biocomposite electronics, explain Ye Zhou of China’s Shenzhen University and colleagues in the journal Science and Technology of Advanced Materials. The scientists expect that including biocomposite materials in the design of electronic devices could lead to vast cost saving, open the door for new types of electronics due to the unique material properties, and find applications in implantable electronics due to their biodegradability. For example, there is widespread interest in developing organic field effect transistors (FET), which use an electric field to control the flow of electric current and could be used in sensors and flexible flat-panel displays. Flash memory devices and biosensor components made with biocomposites are also being studied. For example, one FET biosensor incorporated a calmodulin-modified nanowire transistor. Calmodulin is an acidic protein that can bind to different molecules, so the biosensor could be used for detecting calcium ions. Researchers are especially […]

Funding boost for UC research on airborne microplastics

Could microplastics in the atmosphere play a role in climate change UC atmospheric chemist Dr Laura Revell is leading an investigation into this important question, with the support of a $300,000 Fast-Start grant from the 2019 Marsden Fund Te Pūtea Rangahau. In July 2019, a new report by the Royal Society Te Apārangi highlighted the issue of waste plastics in Aotearoa, noting that the amount of plastic produced each year has doubled over the last 20 years and is still growing rapidly. Less than 20 per cent of the waste plastic generated each year is recycled worldwide. Much of this plastic waste piles up in landfills or the natural environment and, as it breaks down, produces microplastics that contaminate waterways, oceans and land. Some also becomes airborne, with microplastics having recently been discovered over several of the world’s megacities as well as in several remote environments throughout the northern hemisphere. Dr Revell, a lecturer in environmental physics, is leading a team looking into what role these airborne microplastics could be playing in climate change. The endeavour has attracted a Marsden Fund Fast-Start grant, awarded to select world-class standard projects by emerging researchers. Joining Dr Revell on the collaborative project are associate investigators Associate Professor Sally Gaw (UC), Professor Eric Le Ru (Victoria University of Wellington) and Dr Andrea Stenke (ETH Zürich). The project’s mentor is UC chemistry researcher Dr Deborah Crittenden. The discovery of atmospheric microplastics is still so recent that it is not known whether they significantly influence Earth’s climate or not. “However, given that they are now being discovered in the atmosphere around the world and that their abundance is expected to increase in future, it is important to understand the role of microplastics in a changing climate,” Dr Revell says. By combining observational work, laboratory investigations and […]

EMEX is forty years old

At the end of 2019, I put together the Media Kit for this year and, as always, was the challenge of gathering feedback on what readers want to read and be informed about. Needless to say, Climate Change sits right up the top of the list as a major area of concern. It involves refocussing our business strategies, environmental care and the way in which we develop our products for key markets. Good will come from climate change – we just don’t know how yet. The way we adapt and the technologies and tools we use will determine our future. And – because technology change is so rapid – keep us on our toes as we continue to refine our products and our companies’ future direction. In Australia, after a devastating few months, rebuilding has commenced throughout the regions of the east coast. It is believed that with the impact of the bushfires there will not be the possibility of a similar event for four years. Hopefully never again! It gives some space – a window of opportunity for the Australian people to consider different and new ways to deal with Climate Change and review the way they have been allowed to tackle bushfire clearance methods and burn off. This year sees the 40th anniversary of EMEX, the major manufacturing and technology exhibition in New Zealand. Held every two years, EMEX places prominence on our manufacturers and technology which supports company success and forward planning. EMEX also brings together industry technocrats and experts who speak on issues which affect our day by day operations. NZ Manufacturer, as a media partner with XPO Exhibitions will again run Preview issues of this trade show – in March and April, with a Review in May issue. Contact me if your company would like […]

Marsden Fund grant supports UC study on ‘killer robots’ debate

First there was gunpowder, then nuclear weapons. Now another revolution in warfighting is underway with the rise of algorithmic warfare using robots and precision targeting technology. Their use is highly controversial but to date there has been no systematic attempt made to map the debate unfolding in academic, intergovernmental, corporate and social media domains. Internationally, the use of lethal autonomous weapons (LAWS) or so-called ‘killer robots’ is being debated at the highest levels. A new University of Canterbury (UC) study, which has recently received a generous grant from the 2019 Marsden Fund/Te Pūtea Rangahau a Marsden, aims to map and analyse this fast-evolving debate. Its findings could help shape the development of effective and ethical regulation of these sophisticated weapons. Dr Jeremy Moses and Associate Professor Amy Fletcher, from the Department of Political Science and International Relations at UC, and Dr Geoff Ford, a political scientist with the UC Arts Digital Lab, aim to delve deeply into this issue in a three-year project starting this year. Their research has attracted a prestigious 2019 Marsden Fund grant of $842,000. Around 12 countries are known to be developing LAWS, among them the United States, China, Russia and Israel. While the perception in those nations is that LAWS are needed to maintain geopolitical balance, groups such as the Campaign to Ban Killer Robots and other international bodies are seeking a global ban on their use. “Proponents argue that autonomous weapons could decrease civilian casualties through enhanced targeting precision and reduce the risks for human soldiers,” Associate Professor Fletcher says. “Opponents fear a world of ‘algorithmic warfare’ in which robots can make decisions to kill in the absence of human oversight and in which the speed and complexity of war accelerates to the point that international rules of conduct are rendered irrelevant.” This project […]

Manufacturing talent: what can you do to bridge the gap?

From 3D printing to blockchain, automation to predictive analytics, the fourth industrial revolution is changing how the manufacturing industry is operating. However, with this rapid transformation comes manufacturing talent challenges, exacerbated by an industry that has struggled to recruit the right people. 29 per cent of manufacturing vacancies are hard to fill and with a rapidly ageing workforce, it becomes increasingly hard for leaders in manufacturing to know where to start when it comes to talent planning. Engineering businesses have always required a unique combination of technical and soft leadership skills, and it remains in short supply. The fourth industrial revolution is affecting all aspects of business because process is no longer about machines and people, but now about data. It is crucial that employees have the imagination and creativity to realise the full potential of digitilisation and end-to-end integration. Finding the right balance between the skills new technology requires and upskilling existing talent pools is the key challenge. Gap in the middle when it comes to manufacturing talent Siemens went through a period of structural reorganisation in 2014 to prepare it for the challenges facing the manufacturing industry, with industrial digitalisation being a key component of its Vision 2020 strategy. Commenting on the reasoning behind the changes in 2018, Siemens president and chief executive Joe Kaeser called digitilisation “the greatest transformation in the history of industry”. Brian Holliday, managing director of Siemens’ Digital Factory, the German manufacturer’s data integration wing, says: “From a talent perspective, many new roles are emerging in app development, connectivity and software engineering. Technology won’t replace people in future factories, but it will augment human effort through artificial intelligence and ‘co-bots’ [robots that work alongside people on the shop floor], so finding the right balance will be crucial to our survival. We won’t build factories in the future without full digital simulation and […]

Retrofitting legacy equipment

Updating legacy machinery to add smart capabilities After her mother took away her devices, a teen girl went viral after allegedly tweeting from her fridge. The reason this was so entertaining is because it’s unexpected — you don’t typically associate fridges with communication, just as you don’t with legacy equipment. Here John Young, APAC director at automation equipment supplier EU Automation, discusses the issues and solutions surrounding retrofitting legacy equipment with smart technology. Legacy equipment was not designed to communicate, but it can be given a new lease of life by retrofitting smart technology — even if it is 20 years old. Retrofitting avoids replacing an entire system by instead adding the required capabilities to equipment that is already installed. Issues with legacy equipment Functional legacy equipment, such as drives, sensors and PLCs, are often the backbone of a factory. As technology progresses, these machines may need to be integrated with newer machines, which come equipped with data collection and communication capabilities. This can cause issues for manufacturers in connectivity and interoperability. New machinery is being produced and saturating the market at an accelerated rate, despite the lifespan of older models not being complete. As technology advances, we don’t want legacy machinery to be left behind — replacing the backbone of the facility would be costly and time-consuming. However, manufacturers don’t want to be held back from collecting data on their processes and equipment that could hold valuable insights. So, asides from ripping entire systems out and replacing it all with new versions, what can we do? Finding a solution Design engineers should aim to implement a roadmap of the factory’s existing digital capabilities and focus on aims, targets and prioritising actions that will effectively increase business value. Some machinery may need replacing with new technology, however, retrofitting viable legacy […]

How viable is additive manufacturing?

The manufacturing and legal issues surrounding additive manufacturing. In 1984, Charles Hull invented the first 3D printer, which used stereolithography to build up a plastic product layer by layer. Over 35 years later, additive manufacturing (AM) is drastically altering a range of industries, from manufacturing to the medical sector. But what are the limitations of the technology? H In some applications, component manufacturing is shifting away from traditional subtractive machining methods and towards additive manufacturing techniques. The broadening of the applications of AM is causing manufacturers to assess the viability of using it in their own facilities. To do this, there are a few considerations to make before turning to 3D technology. Quality not quantity When moving from one manufacturing method to another, quality is a huge factor, particularly in highly regulated industries like aerospace and medical devices. In fact, quality has been one of the major hurdles to the widespread adoption of AM. One critical consideration is that quality and consistency must be the same machine to machine, regardless of location. Powder bed fusion is one of the most frequently used additive manufacturing methods and there is a possibility that it may introduce defects. However, if the process has a constant thermal gradient, it can prevent warping of the product, avoiding the introduction of defects due to incorrect temperatures. Another concern is that unsintered powder will degrade as a result of heat exposure and that this could impact quality, although regular changing of the powder can prevent this from becoming an issue. When investing in an AM system, manufacturers can overcome quality concerns by working with an experienced partner, who provides training and support on best practice. Those looking to invest in AM parts produced elsewhere should be mindful of their supplier’s approach to quality, to ensure that what […]

Connection Technologies Limited – looking forward to the next 20 years

The founder of Connection Technologies, Lewis Woodward, started the business in December 1999. The aim then and still now is to work with the customer and assist them in achieving their goal. “I knew that without a successful customer, I was going nowhere”. 20 years ago, business conditions were different to what they are today. Business then relied on personal contact and who you knew. Then there was no internet and business was largely done with New Zealand based companies. Technical input and having people who knew your business was important. Today “faceless” internet websites located outside NZ shores compete with each other for business. In the “old” days the customer did not need to know the part number of the item they needed, just a description. Today, you must have the part number to order on the web and so often you are drowned with the range of products available “Our aim was to be the best pro-active supplier with a finite range of product focusing on connectors and supporting tooling as might be required for the industrial, military and aviation market”. This was further narrowed down on the basis that Lewis recognised the OEM PCB market in any volume was dying in NZ. The data reticulation industry he had previously been part of was being. fought after at minimal margins, much of the coax market had moved to the data industrial markets. Getting the right staff in any business is always a challenge. Lewis said he was fortunate that an ex-employee from the same industry wanted to move back to Wellington and “this was exactly what we needed. “Hiring knowledgeable staff with industry background has always been a challenge. We needed people who saw sales different from the normal perspective of selling “nuts and bolts” and making their […]

This is what we can really do about climate change

Despite efforts to achieve net-zero by 2050, global emissions are still rising. A new study suggests ways to fast-track efforts to decarbonise the planet. Building a business case for sustainable energy could drive the transition. It’s not too late to stop climate change. According to new research, decarbonising fast enough to stabilise the climate and fast-track the planet to net-zero rests on all of us changing how we think and act – and doing it fast. The report, published in Proceedings of the National Academy of Sciences of the United States (PNAS), identifies six “tipping dynamics”, or interventions, that could act as catalysts to bring about rapid societal and technological change towards a sustainable future. The study highlights the importance of intervening to make fossil fuels less economically – and morally – attractive. A step-change of this kind could bring about tipping points that divert investment and consumer demand away from fossil fuels towards more sustainable energy sources. It says this can be done by: Removing fossil-fuel subsidies and boosting incentives to move to decentralised energy systems and make clean energy production and storage systems more economically competitive. Encouraging financial markets to divest of assets linked to fossil fuels, to divert investment towards less-polluting technologies, leaving investors keen to avoid the prospect of holding ‘stranded assets’ tied to fossil fuels. Building sustainable cities powered by renewable energy. Revealing the “moral implications” of fossil fuels. Disclosing greenhouse gas emissions information. Strengthening climate education and engagement. While awareness of the climate emergency is growing, global efforts to reduce carbon emissions are not moving fast enough to avoid irreversible damage to the planet. Moving from the fossil fuels that drive global warming to cleaner energy sources, such as wind or solar power, is at the heart of global efforts to decarbonize. Yet emissions […]
