New Method 3D-Prints Metal Foam for Cheaper Oil Filters, Noise Isolation

A new method of 3D-printing metal foam has been developed that could lead to cheaper oil filters and better noise isolation in cars and other machinery.

The method, developed by researchers at the University of California, Irvine, involves using a 3D-printer to create a lattice structure out of metal powder. The lattice is then heated to a high temperature, causing the metal to melt and fuse together, creating a solid metal foam.

The resulting metal foam is lightweight and porous, making it ideal for use in oil filters and other applications where a high surface area is needed. The foam can also be used for noise isolation, as the porous structure helps to absorb sound waves.

One of the main advantages of this new method is that it is much cheaper than traditional methods of producing metal foam. The 3D-printing process is much faster and more efficient than other methods, and it also allows for greater control over the structure of the foam.

The researchers believe that this new method could have a significant impact on a wide range of industries, from automotive to aerospace. They are currently working on developing new applications for the metal foam, and are also exploring ways to improve the strength and durability of the material.

Overall, this new method of 3D-printing metal foam has the potential to revolutionize the way we think about manufacturing and engineering. It offers a cost-effective and efficient way to produce high-quality metal foam, which could have a wide range of applications in various industries.

Opinion: A shift to coastal shipping and rail could cut NZ's freight transport emissions. Why aren't we doing it?

New Zealand's freight transport sector is responsible for a significant amount of greenhouse gas emissions. In fact, it accounts for around 18% of the country's total emissions. This is a problem that needs to be addressed if we are to meet our climate change targets and reduce our impact on the environment.

One solution that has been proposed is a shift towards coastal shipping and rail. These modes of transport are generally more fuel-efficient and emit fewer emissions than road transport. They also have the potential to reduce congestion on our roads and improve safety.

So why aren't we making this shift? There are a few reasons. Firstly, there is a lack of infrastructure in place to support coastal shipping and rail. Ports and rail lines need to be upgraded and expanded to accommodate increased freight volumes. This requires significant investment, which may not be feasible for some companies.

Secondly, there is a lack of awareness and understanding about the benefits of coastal shipping and rail. Many companies are simply not aware of the potential cost savings and environmental benefits that these modes of transport can offer. There is a need for greater education and promotion of these options.

Finally, there is a lack of government support for coastal shipping and rail. While the government has set targets for reducing emissions, there has been little action taken to support the shift towards these modes of transport. This includes funding for infrastructure upgrades and incentives for companies to make the switch.

Overall, a shift towards coastal shipping and rail could have significant benefits for New Zealand's freight transport sector. However, there are a number of barriers that need to be overcome in order to make this a reality. It is up to government, industry and individuals to work together to make this shift happen.

Endangered Māori Construction Methods Pass Modern Seismic Testing Demands

For centuries, Māori people in New Zealand have been using traditional construction methods to build their homes and other structures. These methods have been passed down from generation to generation and have become an important part of Māori culture and heritage. However, with the increasing demand for modern seismic testing, many of these traditional methods have been deemed unsafe and have been replaced by modern construction techniques.

Recently, a team of engineers and architects in New Zealand decided to put these traditional Māori construction methods to the test. They wanted to see if these methods could withstand modern seismic testing demands and if they could be used to build safe and sustainable structures in the future.

The team used a combination of traditional Māori construction methods and modern engineering techniques to build a small house. The house was then subjected to a series of rigorous seismic tests to see how it would hold up in an earthquake.

The results were surprising. The traditional Māori construction methods used in the house were able to withstand the seismic testing demands with flying colors. The house remained intact and showed no signs of damage or collapse.

This discovery is significant for several reasons. First, it shows that traditional Māori construction methods are not only safe but also sustainable and environmentally friendly. Second, it highlights the importance of preserving these traditional methods and incorporating them into modern construction practices. Finally, it provides a new avenue for architects and engineers to explore when designing structures that can withstand earthquakes and other natural disasters.

In conclusion, the successful seismic testing of a house built using traditional Māori construction methods is a significant achievement. It demonstrates the resilience and durability of these methods and provides a new perspective on how we can build safe and sustainable structures in the future.

Air-breathing cathode enhances conversion efficiency, durability of alkaline nickel-zinc batteries

Alkaline nickel-zinc batteries are a promising alternative to traditional lithium-ion batteries due to their high energy density and low cost. However, these batteries have been limited by their short cycle life and low conversion efficiency.

A team of researchers from the University of Waterloo has developed a new air-breathing cathode that can enhance the conversion efficiency and durability of alkaline nickel-zinc batteries. The cathode is made of a porous carbon material that allows oxygen from the air to enter the battery and react with the zinc electrode, which improves the battery's performance.

The researchers tested the new cathode in a prototype alkaline nickel-zinc battery and found that it had a conversion efficiency of 87%, which is significantly higher than the 70% efficiency of traditional alkaline nickel-zinc batteries. The new cathode also showed improved durability, with the battery maintaining 80% of its initial capacity after 1200 cycles.

The air-breathing cathode has the potential to make alkaline nickel-zinc batteries a more viable option for energy storage applications, such as electric vehicles and renewable energy systems. These batteries are also safer and more environmentally friendly than lithium-ion batteries, as they do not contain toxic or flammable materials.

The researchers are continuing to optimize the design of the air-breathing cathode and plan to test it in larger-scale batteries. They hope that their work will contribute to the development of more efficient and sustainable energy storage solutions.

The device, called an artificial synapse, is capable of processing information in a way that is similar to the way the brain processes sensory information.

What is an Artificial Synapse?

An artificial synapse is a device that mimics the function of a biological synapse, which is the junction between two neurons that allows them to communicate with each other. The artificial synapse is made up of a thin film of material that can change its resistance in response to an electrical signal. This change in resistance can be used to store and process information, just like the way the brain processes sensory information.

How Does it Work?

The artificial synapse works by using a process called spike-timing-dependent plasticity (STDP), which is a mechanism that allows neurons to change the strength of their connections based on the timing of their activity. The artificial synapse uses this mechanism to store and process information in a way that is similar to the way the brain processes sensory information.

What are the Applications?

The development of artificial synapse devices has many potential applications, including the development of more advanced artificial intelligence systems, the creation of more efficient and powerful computers, and the development of new medical treatments for neurological disorders.

Conclusion

The development of artificial synapse devices is a major breakthrough in the field of artificial intelligence and has the potential to revolutionize the way we process and store information.

Impossible to keep track: Spain's gamble on green hydrogen

Spain is betting big on green hydrogen as a key component of its energy transition. The country aims to become a major producer and exporter of the fuel, which is made by using renewable energy to split water into hydrogen and oxygen.

Green hydrogen is seen as a promising alternative to fossil fuels in sectors such as transport, industry and heating. It can be used in fuel cells to power electric vehicles, in industrial processes that require high temperatures, and in buildings as a clean source of heat.

Spain has several advantages that make it well-suited to produce green hydrogen. The country has abundant renewable energy resources, particularly solar and wind power, which can be used to generate the electricity needed to produce hydrogen. It also has a well-developed gas infrastructure that can be repurposed to transport and store hydrogen.

However, the road to a green hydrogen economy is not without challenges. One of the biggest hurdles is the high cost of producing hydrogen using renewable energy. The process is still more expensive than producing hydrogen from fossil fuels, which has led some critics to question the economic viability of green hydrogen.

Another challenge is the lack of a clear regulatory framework for green hydrogen. Spain, like many other countries, is still in the process of developing policies and incentives to support the development of a green hydrogen industry.

Despite these challenges, Spain is moving forward with its green hydrogen plans. The country has set a target of producing 4 GW of electrolysis capacity by 2030, which would make it one of the largest producers of green hydrogen in the world. It has also launched several pilot projects to test the feasibility of using hydrogen in different sectors.

Spain's gamble on green hydrogen is a bold move that could pay off in the long run. If the country can overcome the challenges and establish itself as a leader in the green hydrogen industry, it could reap significant economic and environmental benefits.

One of the biggest concerns with self-driving taxis is the safety of passengers. Without a human driver behind the wheel, there's no one to take control in an emergency situation. This means that the car's software and sensors must be able to detect and respond to any potential hazards on the road.

Another concern is the potential for hacking. Self-driving cars are essentially computers on wheels, and like any computer, they are vulnerable to cyber attacks. If a hacker gains control of a self-driving taxi, they could potentially cause a serious accident or even use the car as a weapon.

Despite these concerns, many experts believe that self-driving taxis have the potential to revolutionize the transportation industry. They could reduce traffic congestion, improve safety, and provide a more efficient and convenient way for people to get around.

However, it's important to proceed with caution. Self-driving technology is still in its early stages, and there are many kinks that need to be worked out before it can be considered completely safe and reliable. As with any new technology, there will be risks and challenges that need to be addressed.

In conclusion, self-driving taxis have the potential to change the way we think about transportation. However, we must be mindful of the potential risks and work to address them before we can fully embrace this technology.
