Hexion introduces new bakelite phenolic resin for coatings
Thermoset resin specialist Hexion Inc has developed a new Bakelite phenolic resin for the production of coatings with a formaldehyde (ULEF) content of less than 0.1%.
Bakelite PF 7835 LB Resin offers adhesion and substrate protection when used as a crosslinking agent for polyester and acrylic based container coatings. Crosslinkers bind polymer chains together, and can produce tough and resilient coatings that can resist mechanical deformation, aggressive chemicals and sterilization processes. These coatings are used as protective liners in food cans, aerosol cans, tubes, and other metal containers.
‘Our new Bakelite ULEF phenolic resin will enable customers to formulate higher performance coatings, since they will be able to include a higher phenolic content without exceeding the preferred 0.1% limit of free formaldehyde for these applications,’ said JP Aucoin, vice president and general manager, Global Phenolic Specialty Resins. ‘The extremely low level of free formaldehyde in this resin system is significantly less than that of any other phenolic resin available in the market and provides manufacturers with a variety of formulation advantages, such as anticorrosion properties and a long shelf life.’
The new Bakelite resin features free phenol levels below 0.5%, resulting in lower overall free VOCs. Hexion also offers Bakelite ULEF resins specifically designed for use in anticorrosive and powder coatings.

Topological superconductivity in 2D materials could boost quantum computing
The experimental realization of ultrathin graphene has ushered in a new age in materials research. What started with graphene has now evolved to encompass numerous related single-atom-thick materials, which have unusual properties due to their ultra-thinness. Among these materials are transition metal dichalcogenides (TMDs), which offer several key features not available in graphene and are emerging as next-generation semiconductors.
Now, new research shows that TMDs could even realize topological superconductivity and thus provide a platform for quantum computing – the ultimate goal of a research group at Cornell University led by Eun-Ah Kim, associate professor of physics.
"Our proposal is very realistic – that's why it's exciting," Kim said of her group's research. "We have a theoretical strategy to materialize a topological superconductor ... and that will be a step toward building a quantum computer. The history of superconductivity over the last 100 years has been led by accidental discoveries. We have a proposal that's sitting on firm principles.
"Instead of hoping for a new material that has the properties you want, let's go after it with insight and design principle."
Yi-Ting Hsu, a doctoral student in Kim’s group, is lead author of a new paper on this research in Nature Communications. Other team members include Kim group alumni Mark Fischer, now at ETH Zurich in Switzerland, and Abolhassan Vaezi, now at Stanford University.
The group propose that TMDs' unusual properties favor two topological superconducting states, which if experimentally confirmed will open up possibilities for manipulating topological superconductors at temperatures near absolute zero.
Kim identified hole-doped (positive charge-enhanced) single-layer TMDs as a promising candidate for topological superconductivity. She did this based on the known special locking between spin state and the kinetic energy of electrons (spin-valley locking) of single-layer TMDs, as well as the recent observations of superconductivity in electron-doped (negative charge-enhanced) single-layer TMDs.
The group's goal is a superconductor that operates at around 1K (approximately -457°F), which could be sufficiently cooled with liquid helium to maintain quantum computing potential in a superconducting state. Theoretically, housing a quantum computer powerful enough to justify the power needed to keep the superconductor at 1K is not out of the question, Kim said. In fact, IBM already has a 7-qubit (quantum bit) computer that operates at less than 1K, which is available to the public through its IBM Quantum Experience.
A quantum computer with approximately six times more qubits would fundamentally change computing, Kim said. "If you get to 40 qubits, that computing power will exceed any classical computers out there," she said. "And to house a 40-qubit [quantum computer] in cryogenic temperature is not that big a deal. It will be a revolution."
Kim and her group are working with Debdeep Jena and Grace Xing of electrical and computer engineering, and Katja Nowack of physics, through an interdisciplinary research group seed grant from the Cornell Center for Materials Research (CCMR). Each group brings researchers from different departments together, with support from both the university and the US National Science Foundation's Materials Research Science and Engineering Centers program.
"We're combining the engineering expertise of DJ and Grace, and expertise Katja has in mesoscopic systems and superconductors," Kim said. "It requires different expertise to come together to pursue this, and CCMR allows that."

Graphene helps stem cells to differentiate
Researchers looking for ways to regenerate nerves can have a hard time obtaining the key tools of their trade.
Take Schwann cells, which form sheaths around axons – the tail-like parts of nerve cells that carry electrical impulses – and also promote regeneration of those axons and secrete substances that promote the health of nerve cells. In other words, they're very useful to researchers hoping to regenerate nerve cells, especially peripheral nerve cells outside the brain and spinal cord. But Schwann cells are hard to come by in useful numbers.
So researchers have been taking readily-available and non-controversial mesenchymal stem cells (also known as bone marrow stromal stem cells, because they can form bone, cartilage and fat cells) and using a chemical process to turn them, or differentiate them, into Schwann cells. But it's an arduous, step-by-step and expensive process.
Researchers at Iowa State University are now exploring what they hope will be a better way to transform mesenchymal stem cells into Schwann-like cells. They've developed a nanotechnology-based process that involves using inkjet printers to print multi-layer graphene circuits, and then lasers to treat and improve the surface structure and conductivity of those circuits.
It turns out that mesenchymal stem cells adhere and grow well on the treated circuit's raised, rough and three-dimensional (3D) nanostructures. Add small doses of electricity – 100 millivolts for 10 minutes per day over 15 days – and the stem cells differentiate into Schwann-like cells.
The researchers' findings are reported in a paper in Advanced Healthcare Materials, and are also featured on the front cover. Jonathan Claussen, an Iowa State assistant professor of mechanical engineering and an associate at the US Department of Energy's Ames Laboratory, is lead author. Suprem Das, a postdoctoral research associate in mechanical engineering and an associate of the Ames Laboratory, and Metin Uz, a postdoctoral research associate in chemical and biological engineering, are first authors.
"This technology could lead to a better way to differentiate stem cells," said Uz. "There is huge potential here."
The electrical stimulation is very effective, differentiating 85% of the stem cells into Schwann-like cells, compared to 75% for the standard chemical process. The electrically-differentiated cells also produced 80 nanograms per milliliter of nerve growth factor compared to 55 nanograms per milliliter for the chemically-treated cells.
The researchers report that the results could lead to changes in how nerve injuries are treated inside the body. "These results help pave the way for in vivo peripheral nerve regeneration where the flexible graphene electrodes could conform to the injury site and provide intimate electrical stimulation for nerve cell regrowth," the researchers wrote in a summary of their findings.
The paper reports several advantages to using electrical stimulation to differentiate stem cells into Schwann-like cells. These include: doing away with the arduous steps of chemical processing; reducing costs by eliminating the need for expensive nerve growth factors; potentially increasing control of stem cell differentiation with precise electrical stimulation; and creating a low maintenance, artificial framework for neural damage repairs.
A key to making it all work is the graphene inkjet printing process developed in Claussen's research lab. This process takes advantage of graphene's wonder-material properties – it's a great conductor of electricity and heat, and is strong, stable and biocompatible – to produce low-cost, flexible and even wearable electronics.
But there is a problem: once the graphene electronic circuits are printed, they have to be treated to improve their electrical conductivity. That usually means exposing them to high temperatures or chemicals, and either could damage flexible printing surfaces including plastic films or paper.
Claussen and his research group solved the problem by replacing the high temperatures and chemicals with computer-controlled laser technology. This laser treatment removes ink binders and reduces graphene oxide to graphene – physically stitching together millions of tiny graphene flakes – improving the electrical conductivity more than a thousand times.
This collaboration between Claussen's group of nanoengineers developing printed graphene technologies and Mallapragada's group of chemical engineers working on nerve regeneration began with some informal conversations on campus. That led to experimental attempts to grow stem cells on printed graphene and then to electrical stimulation experiments.
"We knew this would be a really good platform for electrical stimulation," Das said. "But we didn't know it would differentiate these cells."
But now that it has, the researchers say there are new possibilities to think about. The technology, for example, could one day be used to create dissolvable or absorbable nerve regeneration materials that could be surgically placed in a person's body and wouldn't require a second surgery to remove.

New regulations needed for UK composites
A new report published by the University of Southampton suggests that regulation in the use of composites in marine, rail, oil & gas, and construction could save the UK money.
The report suggests that industry and government should work together to put an end to the constraints that currently inhibit the growth and use of composite materials in these sectors. This could bring more than £4 billion worth of benefit to the UK by the year 2030.
The paper entitled ‘Modernising composite materials regulations’, was complied by a multidisciplinary team from Southampton’s Faculties of Engineering and the Environment, and Business, Law and Art (Institute of Maritime Law), supported by the Southampton Marine and Maritime Institute and the University’s department for Research and Innovation Services (RIS).
‘As economic and sustainability pressures have grown, so too has pressure increased to reduce energy consumption (including fuel usage) whilst improving both ‘through-life costs’ and installation times,’ a press release said. ‘All of these factors have increased demand for stronger, lighter, more intelligent and more durable materials tailor made for purpose.’
In 2013, the global market for composite products was US$68 billion, which is predicted to grow to US$ 105 billion by 2030 (UK Composites Market Study). The UK’s share of this market is £2 billion (around 3%) which is estimated to grow to £12 billion or more by 2030 (2016 UK Composites Strategy). This figure could rise to as high as £16 billion if the sectors that have not previously embraced the use of composites were to experience the same rate of growth as the aerospace sector, where the use of composite materials has increased massively over the last three decades, the report suggests.
‘One of the major inhibitors to the uptake of composites in new sectors is that regulations, codes and standards are often inappropriate for composites,’ added the press release. ‘This is because they are both explicitly and implicitly based on named materials, such as steel, and do not permit consideration of composites applications despite the strengths and benefits of the materials in many cases.’
‘Advanced polymer composite materials have a huge potential to shape the modern world,’ said Professor Ole Thybo Thomsen, head of the Infrastructure Research Group at Southampton and co-author of the position paper. ‘The use of composites in aerospace and automobile design is now the norm, but they have much broader potential for use in other sectors such as in building and bridge construction, railway and rail infrastructure, as well as marine and offshore. In aerospace alone, 52% by weight of the latest generation of aircraft are now composed of composite materials.
‘In the UK there is currently very limited coordination and centralisation of the codes and standards data associated with new composite materials,’ added Professor Simon Quinn, director of the University’s Research Institute for Industry (RiFi) and the lead researcher of the paper. ‘There is neither a coherent development of certified testing facilities, nor a formal process for different sectors to share information and best practice. These factors have reduced productivity, discouraged research and development and innovation, and significantly increased the time to market for new composite products.
‘Industry and government have not shared information,’ he added. ‘In the UK there are four government departments dealing with material regulation and the minister with overall responsibility for Health and Safety (the Minister for the Disabled) has neither the mandate nor the resources to harmonise this system. There are also seven agencies involved in regulation, alongside a lack of Suitably Qualified and Experienced Personnel (SQEP), creating a labyrinth of assurance without the guarantee of certification at the end. This is a considerable disincentive to those companies wanting to innovate, and a significant barrier to new companies entering the markets.’
The paper recommends that ‘performance’ assessment methods should be adapted to the needs of each sector to make it easier for manufacturers to prove that their materials can perform to the required operational safety and performance standards related to that sector.
It also calls for one government department to have overall responsibility for regulation, with representation in other departments. The lead department would work closely with the Composites Leadership Forum (CLF) and would oversee material regulatory policy and management of the centre, would have the responsibility to develop codes and standards, and would authorise both UK and nominated overseas test centers.
‘This approach will increase the value, utility and sustainability of the UK’s composites research and by speeding up the ‘route to market’, allowing the UK to both achieve and maximise its predicted market share and prevent the more agile manufacturing nations using our research to gain a first-mover competitive advantage,’ said Rear Admiral Rob Stevens, the lead author of the paper. ‘The next step is create a task group sponsored by government and including key players from the regulatory bodies, industry and academia to take the new regulatory proposition forward in industries that are not utilising composite materials to their full potential.’
An Executive Summary of the paper is available online.

Defective diamonds combine for quantum leap forward
Diamonds with minute flaws could play a crucial role in the future of quantum technology. For some time now, researchers at TU Wien in Austria have been studying the quantum properties of such diamonds, but only now have they succeeded in coupling together the specific defects in two separate diamonds. This is an important prerequisite for the development of new applications, such as highly sensitive sensors and switches for quantum computers. The researchers report their advance in a paper in Physical Review Letters.
"Unfortunately, quantum states are very fragile and decay very quickly," says Johannes Majer, head of the hybrid quantum research group at TU Wien’s Institute of Atomic and Subatomic Physics. For this reason, in-depth research is being carried out with the aim of finding quantum systems that can be used for technical applications. Although several promising candidate systems have been developed, each of which possess specific advantages, until now there has been no system that fulfills all the necessary requirements simultaneously.
"Diamonds with very specific defects are one potential candidate for making quantum computers a reality," says Majer. A pure diamond is made up solely of carbon atoms. In some diamonds, however, a nitrogen atom can replace a carbon atom at specific points, which causes a neighboring anomaly within the atomic structure of the diamond where there is no atom at all, referred to as a 'vacancy'. This defect, consisting of the nitrogen atom and the vacancy, forms a quantum system with a very long-lasting state, making diamonds with these particular flaws ideally suited for quantum experiments.
One important prerequisite for many quantum technological applications is the ability to couple such quantum systems together, which until recently had scarcely been possible for diamond systems. "The interaction between two such nitrogen-vacancy defects is extremely weak and only has a reach of around 10nm," says Majer.
With the help of a superconducting quantum chip that produces microwave radiation, this feat has now been achieved. For a number of years, the team at TU Wien has been investigating how diamonds can be manipulated with the help of microwaves. "Billions of nitrogen-vacancy defects in diamonds are coupled collectively with a microwave field," explains Majer. "In this way, the quantum state of the diamonds can be manipulated and read out."
Now, the team has succeeded in taking the next step: they were able to couple the defects in two different diamonds, one at each end of the chip, thus producing an interaction between the two diamonds. "This interaction is mediated by the microwave resonator in the chip in between; here, the resonator plays a similar role to that of a data bus in a regular computer," says Majer.
This coupling between two separate diamonds can be switched on and off selectively. "The two diamonds are rotated against each other at a certain angle," explains Thomas Astner, also at TU Wien and lead author of the paper. "Additionally, a magnetic field is applied, with the direction playing a decisive role: if both diamonds are aligned at the same angle within the magnetic field, then they can be coupled using quantum physics. With other magnetic field directions, it is possible to investigate the individual diamonds without coupling".

Next-generation transistors revealed in print
Graphene Flagship researchers from AMBER at Trinity College Dublin in Ireland have fabricated printed transistors consisting entirely of layered materials. Reported in a paper in Science, the team’s advance could be used for cheaply printing a range of electronic devices from solar cells to light-emitting diodes (LEDs), with applications from interactive smart food and drug labels to next-generation banknote security and e-passports.
The researchers were led by Jonathan Coleman from AMBER (the Science Foundation Ireland-funded materials science research center hosted in Trinity College Dublin), in collaboration with the groups of Georg Duesberg at AMBER and Laurens Siebbeles at TU Delft in the Netherlands. They used standard printing techniques to combine graphene flakes as electrodes with tungsten diselenide and boron nitride as the channel and separator (two important parts of a transistor) to form an all-printed, all-layered materials, working transistor.
All of these are flakes are just a few nanometers thick but hundreds of nanometers wide. Critically, it is the ability of flakes made from different layered materials to encompass the full range of electronic properties – conducting (in the case of graphene), insulating (boron nitride) and semiconducting (tungsten diselenide) – that allows them to produce the building blocks of electronics. While the performance of these printed layered devices cannot yet compare with advanced transistors, the team believe there is great scope for improving the performance of their printed thin-film transistors (TFTs) beyond the current state-of-the-art.
“In the future, printed devices will be incorporated into even the most mundane objects such as labels, posters and packaging,” says Coleman. “Printed electronic circuitry will allow consumer products to gather, process, display and transmit information: for example, milk cartons will send messages to your phone warning that the milk is about to go out-of-date. We believe that layered materials can compete with the materials currently used for printed electronics.”
All of the layered materials were printed from inks created using a liquid exfoliation method previously developed by Coleman and already licensed. Using liquid processing techniques to create the layered material inks is especially advantageous because it yields large quantities of high-quality layered materials, allowing circuitry to be printed at low cost.
