Scientists have formed an unusual new alliance in their fight against climate change. They are using bacteria to help them extract rare metals vital in the development of green technology. Without the help of these microbes, we could run out of raw materials to build turbines, electric cars and solar panels, they say.

The work is being spearheaded by scientists at the University of Edinburgh and aims to use bacteria that can extract lithium, cobalt, manganese and other minerals from old batteries and discarded electronic equipment. These scarce and expensive metals are vital for making electric cars and other devices upon which green technology devices depend, a point stressed by Professor Louise Horsfall, Chair of Sustainable Biotechnology at Edinburgh.

“If we are going to end our dependence on petrochemicals and rely on electricity for our heating, transport and power, then we will become more and more dependent on metals. All those photovoltaics, drones, 3D printing machines, hydrogen fuel cells, wind turbines and motors for electric cars require metals – many of them rare – that are key to their operations,” said Horsfall.

Politics is also an issue, scientists warn. China controls not only the main supplies of rare earth elements, but dominates the processing of them as well.

“To get around these problems we need to develop a circular economy where we reuse these minerals wherever possible, otherwise we will run out of materials very quickly,” said Horsfall. “There is only a finite amount of these metals on Earth and we can no longer afford to throw them away as waste as we do now. We need new recycling technologies if we want to do something about global warming.”

And the key to this recycling was the microbe, said Horsfall.

“Bacteria are wonderful, little crazy things that can carry out some weird and wonderful processes. Some bacteria can synthesise nanoparticles of metals, for example. We believe they do this as a detoxification process. Basically they latch on metal atoms and then they spit them out as nanoparticles so that they are not poisoned by them.”

Using such strains of bacteria, Horsfall and her team have now taken waste from electronic batteries and cars, dissolved it and then used bacteria to latch on to specific metals in the waste and deposit these as solid chemicals.

“First we did it with manganese. Later we did it with nickel and lithium. And then we used a different strain of bacteria and we were able to extract cobalt and nickel.”

Crucially the strains of bacteria used to extract these metals were naturally occurring ones. In future, Horsfall and her team plan to use gene-edited versions to boost their output of metals.

“For example, we need to be able to extract cobalt and nickel separately, which we cannot do at present.”

The next part of the process will be to demonstrate that these metals, once removed from old electronic waste, can then be used as the constituents of new batteries or devices.

“Then we will know if we are helping to develop a circular economy for dealing with green technologies. New legislation has decreed that by the next decade recycled metals will have to be used at significant levels for manufacturing new green technology devices. Those goals will be hard to achieve and bacteria will be vital in achieving them.”

Roll Forming: How To Get The Most Out Of Thin Materials

Christellee — Wed, 03 Jul 2024 09:24:29 +0000

Andrea Dallan, CEO of Italy-based Dallan Spa explains it’s a different ball game processing thin materials in roll forming, as it requires very different calculation and adjustment tools compared to thick materials.

The thinner the material, the more difficult it is to evaluate the spring back for open profiles, as well as for closed profiles. At Dallan, we have been developing specific calculation tools and algorithms for thin metal sheets since 1978. This has driven the development of our company and has become the distinctive factor of Dallan machines and equipment.

The image shows the accuracy of Dallan roll forming machines in a comparison between the theoretical design and the final result of a rolling shutter profile with a thickness of 0.20mm plus paint. The rolling shutter profile is one of the most technical made by Dallan systems. Since it is not a static profile, the hook needs to work correctly during winding and unwinding for the entire lifetime of the product.

The Original 1974 Study Of Thin Materials

In 2019, 45 years after its publication, we published the thesis written in Italian. It was written by our founder, Sergio Dallan, for his university degree.

The subject was the cold forming of thin metal sheets. Starting from this study, entitled “The Design Of Rollers For Light Profiles”, published in its original version and complete with all its formulas, our company gradually began to develop, first as a design studio, subsequently as a manufacturer of roll forming machines for the Italian market followed by the international market.

The formulas were included in the original Dallan roller development software, which we still use today. It has been updated with the experience accumulated in 40 years of work.

Characteristics Of Coatings For Roll Forming And Bending Radii

In addition to developing special techniques for thin materials, from the very beginning we started working in sectors such as metal suspended ceilings and rolling shutters, where many profiles are made of pre-painted material. When forming an aesthetic profile with a pre-finished surface, particular attention is needed in the design to guarantee product quality.

Vietnam Real Estate Market In 2024 Shows Signs Of Recovery

Christellee — Tue, 09 Apr 2024 07:21:57 +0000

1,300 Vietnamese real estate companies folded in last year, according to Vietnam Express. This time, Hanoi Times paints an optimistic outlook for 2024 albeit for the housing market. There will be differences in the timing of the recovery across segments.

Nearly 50% of respondents in Vietnam’s real estate industry believe the market will recover in the second half of 2024, according to Vietnam Report’s latest survey. This is a stark contrast to Vietnam Express’ earlier report that some 1,300 real estate companies went bankrupt in 2023, an 8% increase from 2022, according to the General Statistics Office.

Companies that suspended business for a limited time increased by 21% compared to 2022, while companies waiting to complete procedures to be disbanded increased by 29%. On average, 107 businesses go bankrupt every month, while the number of new businesses being established dropped by 45% compared to 2022.

Vietnam’s real estate market has been in hot water since 2022, and the situation persisted until now, even with assistance from the government. Experts said there were issues regarding the law, land handovers, pricing and capital, among others. The precarious real estate scene caused several projects to be delayed, incurring losses for construction and material businesses.

Statistics from the Ministry of Construction revealed the total revenue of several companies under the ministry, including HUD, Coma and Vicem, decreased by 16% compared to 2022. Their profit dipped by 66% compared to 2022, to VND1.38 trillion ($56.86 million).

In a report sent to the Economic Commission, the construction ministry said the real estate market still harbours instabilities, stemming from the risk of a crash, lack of supply and inappropriate goods structure, among other factors.

Vietnam Report CEO Vu Dang Vinh said companies expect three factors to boost their performance in 2024: gradual economic recovery, lower interest rates, and successful application of digital transformation in management and operations. Real estate experts and businesses agree that the real estate market will show more positive signs in 2024 than in 2023, but there will be differentiation among different segments, according to the survey.

The report highlighted office leasing and industrial real estate segments are benefiting from favourable factors such as geographical location, public investment in infrastructure, strong FDI inflows due to the impact of newly signed free trade agreements, the “China+1” strategy, stable economic-political environment, and competitive advantage due to low industrial land prices compared to other countries in the region.

These factors drive development and investment attractiveness of the office leasing and industrial real estate segments. Some 34.5% of companies predict that the industrial real estate segment will thrive in the first half of 2024. Regarding the office leasing market, about 35.7% of respondents forecast a recovery in the second half of 2024.

Residential real estate, high-end apartments and resorts will experience a slower recovery than other segments due to oversupply after a period of rapid growth and people’s caution in investing in these segments, according to the report.

The focus in these segments is on the vision of building one million social housing units between 2021 and 2030, along with planning for land reserves, incentives for investors, and adjustments to sales policies. This will be an opportunity to increase the supply of housing and provide access to social housing for people on low incomes, the report stresses.

The Vietnam Report also examines the state of the real estate market in 2023, a challenging year for the industry as global and Vietnamese economic growth slowed, affecting people’s incomes and reducing the number of successful real estate transactions. By the end of 2023, the number of dissolved real estate companies reached 1,286, an increase of 7.7% from 2022, according to data from the General Statistics Office.

3,705 real estate companies that temporarily suspended operations, an increase of 47.4% compared to 2022. In 2023, 41.2% and 16.1% of the businesses experienced revenue and profit declines of less than 25%, respectively. In addition, most of these companies will trim their payroll by 42.9% in 2023.

Many real estate companies surveyed said the three most important drivers of their business results were the company’s reputation and brand in the market, a skilled and experienced workforce with high discipline, and efficient cost reduction and utilisation measures, Vinh said.

As a result, he said, leveraging their existing position and reputation, along with cost-cutting measures, has helped real estate companies maintain operations, with hopes for a more vibrant market in the current year.

The Age Of New Materials Sandvik Coromant: Is The Future Now?

Admin — Wed, 04 Oct 2017 20:10:48 +0000

Throughout history, materials and advances in material technology have influenced humankind. Now we just might be on the verge of the next shift in this type of technology, enabling products and functions we never believed possible. Contributed by Sandvik Coromant

Demands from Sandvik Coromant industry are requiring that materials be lighter, tougher, thinner, denser and more flexible or rigid, as well as to be heat- and wear-resistant. At the same time, researchers are pushing the boundaries of what we imagine is possible, seeking to improve and enhance existing materials and at the same time come up with completely new materials that, while years away from day-to-day use, take us down entirely new technological pathways.

Sandvik Coromant Sky’s The Limit

Based on the research we’re seeing today, the field of applied material science is set to move in new, almost science-fiction-like directions. Looming resource scarcity is demanding innovations and out-of-the-box thinking. On the materials front, composites with such desirable attributes as low weight, high strength and high durability look likely to take a larger market share, and more of these materials will likely be based on renewable resources, as the need for this becomes greater.

The most promising jewel in this arena is graphene.

Sandvik Coromant Graphene is a single atom thick (1 million times thinner than a human hair) but 200 times stronger than steel by weight, extremely flexible, super light and almost transparent with great heat and electricity conductivity. It’s the stuff legends are made of.

In fact, researchers at Nankai University in Tianjin, China, recently found that a graphene sponge can turn light into energy, thus taking humankind one step closer to a fuel-free spacecraft, one that runs by the light of the sun.

Heading For The Graphene Revolution

Sandvik Coromant Graphene was discovered almost accidentally when professors Andre Geim and Kostya Novoselov at the University of Manchester in England experimented with pencils and sticky tape in 2004. In 2010, Geim and Novoselov won the Nobel Prize in physics for their graphene research, and the European Union subsequently committed 1 billion euros to fund the Graphene Flagship, a research initiative aimed at speeding up the development of commercial applications.

Sandvik Coromant Potential areas of application range from water purification and energy storage to household goods, computers and other electronics. Meanwhile, although graphene-related patents are increasing by the thousands, widespread industrial adoption of graphene is limited by the expense of producing it – but that may be about to change. Researchers at the University of Glasgow have found a way to produce large sheets of graphene at a cost some 100 times cheaper than the previous production method.

Synthetic skin, capable of providing sensory feedback to people with limb prostheses, is one of the many possibilities that could grow out of this development. “Graphene could help provide an ultraflexible, conductive surface that could provide people with prosthetics capable of providing sensation in a way that is impossible for even the most advanced prosthetics today,” says Dr. Ravinder Dahiya, who led the research team at the University of Glasgow.

Death Of Metals?

Sandvik Coromant Metals have dominated the industry, defining entire periods of human history. Such long-term use has created a wealth of information and expertise, but scientists and researchers continue to work to extend the boundaries of these materials. Nanomaterials figure prominently in this research, enhancing metals and opening up new application areas. Developments in metal matrix nanocomposites – composites that partially consist of carbon nanotubes or nanoparticles – could usher in a new era of weight reduction in the aerospace industries, with added strength and stiffness.

Self-Healing Properties

Nanocomposite research Sandvik Coromant is opening up the possibility of materials that fix themselves, much the way the human body heals itself. Researchers at the Beckman Institute’s Autonomous Materials Systems Group at the University of Illinois in the United States are working on fibre-composite materials with self-healing properties that involve the integration of healing agents that are released to mix and polymerise when a defect is detected.

“Materials that heal themselves are coming,” says material scientist Mark Miodownik. For now, what’s technically possible isn’t close to being reasonable economically, but the possibility of fixing anything on the fly, from airplane wings to bike frames to car parts crucial to the safety of vehicle and passengers, is on the horizon. And it will have a massive impact on product development, life cycle and sustainability. Researchers are even working on materials that will allow a roadway to repair itself instead of waiting for an overworked, understaffed maintenance crew.

Outperforming Nature

For thousands of years, material science moved forward through a series of accidental discoveries of materials that existed in nature. Today researchers are looking beyond what’s in the natural world, combining multiple conventional materials or parts of materials and focusing on the inherent structure or pattern, to create properties that do not exist in nature – or at least haven’t been discovered thus far.

One such development is an arrangement of ridges formulated to resemble a shark’s skin. The micropattern, named Sharklet, protects against the harbouring and transmission of bacteria and is being developed for use in hospital and health-care settings.

Another materials development involves invisibility. Physicists in several countries are working on metamaterials that hold the promise of rendering objects invisible by cloaking them with a material that can bend the electromagnetic radiation, such as light, around an object, creating the illusion that it isn’t really there.

Key Driver: Sustainability

Sandvik Coromant Material science and the development of new materials, as well as improvement of existing ones, look likely to play a crucial role in such areas as resource scarcity and sustainability. New materials – for example, light-absorbing building materials – could help counter global warming.

We seem to be on the verge of a new age, one that is characterised not only by digitalisation and the Internet of Things but also, importantly, by new materials – materials that can make our future easier, safer and more sustainable. The sky really is the limit.
