Watch a Plasma Cutter Make Quick Work of a Stainless Steel Bar at 30,000 FPS




Behold the awesome glory of the plasma cutter. These torches create electrically conductive jets of hot plasma that will cut through just about any conductive material, from steel to to brass. In the video below, the YouTube channel Warped Perception gives us a look at one of these at work on a bar of steel in slow motion.


The both educational and entertaining video exhibits how smooth and clean this tool can cut. At 30,000 FPS using a Phantom V2512 Camera, plasma cutting has never been so clear. The insanely hot cutter makes easy work of a bar of solid stainless steel as well as a bar of mild steel.

If you're going to equip your own garage with one of these viciously hot tools, make sure you have your faceplate, and make sure you know how to use it first.

Relax inside a giant golden Swedish Stainless Steel egg




Glimmering in solitude among the snow-laden landscape, stands a distinctive public sauna erected by artistic duo mats bigert and lars bergström. titled the solar egg, the installation stands at five meters high and four meters wide; the smooth and multi-faceted envelope or ‘shell’ wrapped in gold-plated stainless steel. a total of 69 separate pieces make up the egg’s exterior, reflecting glimpses of the swedish town of luossabacken in kiruna in the distance.


The project was commissioned by swedish developer riksbyggen to commemorate the growth of kiruna’s urban landscape which involves the relocation of entire city districts in response to ground subsidence caused by decades of iron ore mining. bigert & bergström’s response saw an oval-shaped sauna being created as a symbol of rebirth and as an homage to kiruna’s iron ore fields. a delicately-framed staircase reveals the entrance, an opening that appears to have cracked open to invite guests inside. the multi-faceted character is continued inside but instead, finished in pine wood. at the center, heat is emitted by a heart-shaped wood-fired burner.

Located in sweden’s northernmost town, the solar egg is a warm welcome and an intimate space of reflection for locals and visitors to take part in the unique sauna experience. created with the intention to be transportable, the faceted-structure can be de-constructed piece-by-piece and relocated to different locations within the city.

‘Saunas are places that fascinate. when riksbyggen asked us to interpret kiruna, we felt it was natural to explore a space that unites and encourages conversation,’ comments artists mats bigert and lars bergström. ‘saunas are sacrosanct places where you can discuss all manner of things - from the big to the small.’

The project continues bigert & bergström’s exploration with humanity’s relationship to climate, nature, energy and technology. on this occasion, the solar egg stands as a sculptural symbol that prompts thoughts of rebirth and an incubator that nurtures conversation and exchanges of ideas.

Consisting of 69 separate pieces, the installation can be taken down and moved to different locations

Just how is Galvanised and Stainless Steel different?



Galvanised and stainless steel look exactly the same to the untrained eye, but they are in fact completely different in terms of composition, weight, strength and application. It is important to be able to know the key differences and tell them apart when choosing duct work and steel hoppers, as each type of steel is suitable for a particular use and work environment.


Galvanised Steel:
Galvanised steel is created during the process of applying a protective zinc coating to steel or iron, which prevents rusting. Some of the most common methods of creating this type of steel are by hot-dip galvanising, where parts of the steel are placed into a bath of molten zinc, and electro-galvanising, which is done by immersing steel in an electrolyte solution. Galvanised steel is covered in a rust-protective layer, which is approximately a millimetre thick.  This layering can wear off over time, and if scratched or damaged, can begin to rust.

Stainless Steel:
The manufacture of stainless steel involves a mixture of chromium and regular carbon steel. Unlike galvanized steel, stainless steel has chromium throughout, which means that it has a protective layer in place at all times. Stainless steel is an excellent material for ductwork, and any machinery or systems which have moving parts, as it is scratch resistant. Stainless steel is also non-reactive to corrosive chemicals, which is beneficial for the industrial and manufacturing sectors.

Stainless steel is extremely durable, which provides a lot of cost saving benefits, it resists corrosive and harsh substances, cannot rust and is extremely strong. Unlike other materials, stainless steel remains strong and will even retain its shape in extreme heat.

Flying Fish can Fly Further thanks to Stainless Steel!


At the end of March the Australian company FishPac, the only approved oxygen-sustained live seafood air fright transport system in the world, revealed its new stainless steel container, which will allow fish to travel to a greater distances while reducing mortality rate.


The new container was designed and manufactured in Melbourne, Australia and the company envisages that it will reduce the cost for shippers and will increase the distance at which live seafood can be transported.

The stainless steel version replaces the traditional ceramic container and thus solves the issue with breakage. In addition it also features a highly specialized sintered metal filtering process and works on higher pressure rating, which removes back pressure from the system. The overall effect is an expect rate of 0 to 1% mortality rate of transported seafood.

The new diffusers are being delivered to various freight operators worldwide to be tested with variety of seafood.

China's latest supertall skyscraper hailed world's fourth-tallest



The Ping An Finance Centre has been hailed the world's fourth-tallest skyscraper by the influential Council on Tall Buildings and Urban Habitat (CTBUH). Rising to a total height of 599 m (1,965 ft) in Shenzhen, China, the tower is the latest in a series of impressive supertall skyscrapers by Kohn Pedersen Fox. Located in Shenzhen's central business district, the mixed-use Ping An Finance Centre comprises 462,000 sq m (4,973,000 sq ft) of floorspace, spread over 100 floors. Each day, the building will accommodate up to 15,500 workers and 9,000 visitors to its observation deck, which lies at a height of 550 m (1,804 ft), making it just a few meters short of the world's tallest observation deck in the Burj Khalifa.


The skyscraper is anchored by a large glass and stone podium that provides an additional five floors of retail space. A central atrium serves as a public lobby and provides an impressive location for meeting, shopping and dining, while allowing plenty of daylight inside too.

Though the Ping An Finance Centre's tapering form looks uncomplicated from a distance, closer inspection reveals an interesting sculpted facade that's shaped to mitigate the effects of wind. Stone chevron-shaped columns converge at the tower's top and stainless steel protrusions are aimed at protecting the building against lightning strikes. According to the CTBUH, the Ping An Finance Centre boasts the world's largest stainless steel facade, with a total of 1,700 tons (1,542 kg) of the metal installed for its corrosion resistance qualities, to stand up against Shenzhen's salty coastal atmosphere.

Currently, only the Burj Khalifa, Shanghai Tower, and Makkah Royal Clock Tower are taller worldwide. Indeed, KPF is a heavyweight presence in CTBUH's entire top 10 rankings of tallest buildings and is also responsible for the 6th place CTF Finance Centre, 8th place Shanghai World Financial Centre, and 9th place International Commerce Centre. In addition, its Lotte World Tower will likely soon be recognised in the rankings in 5th place, a position currently held by SOM's One World Trade Centre.

The Ping An Finance Centre was actually completed last year but was just recognised as complete by the CTBUH this week.

Copying Bone to create a stronger Stainless Steel



Research finds that introducing crack-resisting structures makes steel tougher against fatigue.


(Inside Science) -- Nature has relied on bone to make up skeletons for hundreds of millions of years. Now scientists taking a page from nature have developed a new kind of steel that imitates bone, which resists cracking under repeated pressure for far longer than conventional kinds of steel.

Steel helps make up the skeletons of suspension bridges that are miles long and skyscrapers more than a half-mile tall. However, in many ways, bone outclasses steel. For instance, bone can bear roughly as much weight as stainless steel while weighing four or five times less.

Previous research also found that despite the brittle minerals that bone is mostly made of, it is highly resistant to fractures because of the way in which it is structured. This led study co-author Cem Tasan, a metallurgist at the Massachusetts Institute of Technology, and his colleagues to explore whether steel that mimicked bone's structure could prove more resistant to fatigue.

Steel fatigues when it experiences repeated stress -- for instance, when trucks drive over bridges, or when airplanes undergo pressure changes during ascents and descents -- with microscopic cracks forming and growing over time. Many sudden and sometimes life-threatening failures of everything from power plants to spacecraft are due to fatigue. For this reason, these structures are often built with large safety margins that add to costs.

Prior work suggested that bone resists fracturing because its lattice like internal structure keeps cracks from spreading. "If you look at the structure of bone with increasing magnification, you'll see more and more complexity to it as you zoom in," Tasan said. "That's what helps it fight cracks."

To design a bonelike metal alloy, Tasan and his colleagues investigated two kinds of steel with structures comparable to that of bone -- ferrite-cementite pearlitic steel and martensite-austenite transformation-induced plasticity steel. These steels possessed key properties that limited the growth of cracks, Tasan said.

The ferrite-cementite steel is nanolaminated, meaning that its structure is separated into many layers only nanometers, or billionths of a meter, wide. This helps keep cracks from spreading beyond the layers where they start.

The martensite-austenite steel is metastable, which means that one of the kinds of crystal making up its structure can switch between different states of stability. This helps the steel absorb the energy of spreading cracks and even close them back up.

And finally, both these kinds of steel are multiphase, which means that they have multiple kinds of crystals in their structure with different levels of hardness. This means that when cracks want to spread, they prefer not to do so in straight lines. Since the resulting fractures cover more area, they experience more friction against their surroundings, decelerating their growth.

The scientists then developed a new alloy that combined all three of these properties. On its smallest levels, this steel was composed of layers just 100 to 300 nanometers wide. (In comparison, the average human hair is about 100,000 nanometers in diameter.)

The researchers found that their new alloy was significantly more resistant to cracking than a type of steel typically used in automobile bodies. When subjected to repeated cycles of stress, the automotive steel developed microscopic cracks after roughly 10,000 to 100,000 cycles, while the new alloy only did so after about 10 million cycles, said study lead author Motomichi Koyama at Kyushu University in Fukuoka, Japan.

"This is a truly fantastic piece of research," said materials scientist Daolun Chen at Ryerson University in Toronto, who did not take part in this study. This work could lead to the development of advanced fatigue-resistant steels that "will have important implications for load-bearing structural applications in the automotive and aerospace industry," Chen said.

Future research can better control the metallurgical processes to manufacture this new steel and related alloys to prevent the formation of impurities that can weaken them, Tasan said.

Stainless Steel T-Shirts turned into Radios? whatever next!



Posters and t-shirts are being turned into (very) local FM radio stations


What if a band's poster could actually transmit a sample of their music to your phone, or your t-shirt could monitor your vital signs while you exercise? Researchers at the University of Washington (UW) have pioneered a technique where everyday objects can be embedded with transmitters that piggyback ambient FM signals to send data to nearby smartphones and radios using almost no power.

The technique makes used of backscattering, which is the reflection of waves, particles, or signals back in the direction they came from. The system uses a low-power reflector to encode specific audio or data on top of reflected signals from an existing FM broadcast, with the data sent on an adjacent band so as not to interrupt any current radio transmissions. The key benefit of the technology is that it has an extraordinarily low level of power consumption, meaning that it can easily be incorporated into everyday objects at a low cost.

"The challenge is that radio technologies like Wi-Fi, Bluetooth and conventional FM radios would last less than half a day with a coin cell battery when transmitting," says study co-author and UW electrical engineering doctoral student Vikram Iyer. "So we developed a new way of communication where we send information by reflecting ambient FM radio signals that are already in the air, which consumes close to zero power."

The antennas are made of thin copper tape and can be simply embedded into objects like advertising posters or articles of clothing. Initial demonstrations of the technique showed the total power consumption of a transmitter embedded into a poster to be as little as 11 microwatts – an output that could run uninterrupted off a small coin-cell battery for two years.

The team at UW has previously showed how an ambient backscatter technique can convert existing TV and cellular signals into electricity, allowing for battery-free sensors to be embedded into objects. This latest innovation excitingly evolves that technique allowing objects to send more complex information on top of existing radio frequencies.

"What we want to do is enable smart cities and fabrics where everyday objects in outdoor environments – whether it's posters or street signs or even the shirt you're wearing – can 'talk' to you by sending information to your phone or car," explains Shyam Gollakota, one of the lead authors in the research.

Using materials such as conductive threads, these flexible FM antennas can be woven into fabrics, creating smart clothes that sense a wearer's vital signs and transmit information to a nearby smartphone. The low-power consumption of the system means that such clothing wouldn't require large batteries, allowing them to become much more functional as wearable items.
The antennas can be woven into textiles creating smart fabrics that track vital body signs and...

The UW team has produced two working proof-of-concept prototypes demonstrating the technology. The first was dubbed a "singing poster" that transmitted portions of a band's music to a smartphone up to 12 ft (3.6 m) away, or a car up to 60 ft (18 m) away.

Stainless Steel fibres:
The second demonstration involved sewing a conductive three-ply thread made of Stainless Steel fibers into a cotton t-shirt. The fibers were chosen specifically as they don't oxidize, enabling the garment to be easily washed with no damage to the transmitter. The smart t-shirt was found to be able to transmit data at rates up to 3.2 kilobits per second to a nearby smartphone.

The combination of such minimal power consumption with the piggy backing of FM signals that are so pervasively present in modern cities, make this an innovation that takes us one step closer to a world filled with smart objects that communicate information instantly as soon as they are approached.
