A New Centre for Additive Layer Manufacturing (CALM) opened in UK

The University of Exeter opened its Center for Additive Layer Manufacturing (CALM), which features machines that can work with several materials to allow for a huge range of possibilities in potential products. The first facility of its kind in the UK, the Center offers the EOSINT P800 laser sintering system from EOS, which can build parts at temperatures up to 385°C and enables production using high-performance polymers, such as PEEK.

The European Aeronautic Defense and Space Company N.V. (EADS) supports CALM, which is in part financed by the EU and the European Regional Development Fund under the competitiveness operating program (£1.5 million).

The partnership enables the University of Exeter to provide additive manufacturing facilities for the southwest of the UK, further helping to raise awareness for a technology that is currently shifting paradigms in design and manufacturing, says Dr. Hans J. Langer, founder and CEO of EOS. The company also looks forward to expanding the use of the PEEK material, which is being processed on the P800, in the aerospace, medical and motorsports arena.

High performance materials, including PEEK, are mechanically strong and wear-resistant in the toughest of operating environments. Parts made of PEEK are being developed as an alternative to metals for applications including aerospace parts and medical instruments. As a result, the manufacturing process for prototypes and products is being simplified.

Businesses that are producing prototypes and developing products can now benefit from this pioneering £2.6 million facility at the University of Exeter. The facility will enable businesses, entrepreneurs and researchers to harness the potential of additive manufacturing. The centre is offering heavily subsidised rates to SMEs in Devon, Dorset, Wiltshire and Cornwall, giving smaller businesses access to world-class facilities at affordable prices.

With this EOS manufacturing technology, complex or bespoke parts and complete products can be created by building them up one layer at a time via laser sintering, thus significantly reducing the time it takes to get a product from the design stage into market. Businesses will also benefit from the technical expertise of CALM staff, gained through their experience in industry.

Harmful Food Additives Found at Snacks and Beverages in Taipei Teashops

Cue:Sometimes our vision clears only after our eyes are washed away with tears.



A random sampling revealed that some of the ingredients added to snacks and beverages sold at shops in Taipei failed a test for a problematic additive, Taipei City health officials told a press conference yesterday.

The city’s Department of Health randomly inspected 54 ingredients often added to drinks and sweets sold at teashops, and found three of them did not meet regulations, constituting a 5.6 percent failure rate.

The three items were found to contain high levels of sorbic acid, a type of food preservative that is unfit for consumption, Food and Drug Division Director Chen Li-chi said.

The ingredients found to be unsafe were marble-sized black tapioca balls, taro beads and konjac, a long strand of chewy jelly consumed throughout Asia.

Officials have ordered that sales of the three products cease and any stocks be destroyed. They also fined the suppliers of one of the products, who was registered in the city.

Since the other two manufacturers who provided the unsafe items are not located in Taipei, the city government has forwarded the case on to the appropriate jurisdictional authorities, Chen said.

The officials called for food manufacturers to regulate themselves according to the Act Governing Food Sanitation and reminded the public that violators face fines between NT$30,000 and NT$150,000.

Results of future food inspections will also be posted on the health agency’s Web site, the officials said.

Digression:Everything will be okay in the end. If it's not okay, it's not the end.

New Additives Make the Oil Changes Changing

Advances in oil and automotive technology mean the old oil change rule "you should change your car's oil every 3,000 miles" no longer applies.



The reason oil needs changed is because it gets dirty and the additives inside get used up, just as they're designed to do. But by the late 80's, big changes in car manufacturing made them much cleaner.

Now, drivers can go 5,000 to 7,000 miles between oil changes, and some models can go as long as 20,000 miles.

The reason oil needs changed is because it gets dirty, and the additives inside get used up, just as they're designed to do, but by the late 1980s, big changes in car manufacturing made them much cleaner.

"We were carbureted then, we're fuel injected now. The rings are better now. We have better engines, better metal, so we do not get the contaminants and the sludge in the oil like we used to," said Joe Smith, automotive instructor.

Some companies are introducing re-refined oil because oil never wears out. Re-refined oil is used oil that's cleaned with new additives added back in.

"All the oil manufacturers have to meet a standard for oil, but they can meet a minimum standard or, if their oil's more expensive, they could increase their additive package because that's the most expensive part of the oil," said Richard Augustus, fuel engineer.

In fact, the better the additive package in oil the longer you can go without a change.

In the long run, it could actually save you money.

Chemists inside the BG lab in Wichita, KA, work diligently to mix and test additives, constantly keeping up with newer and tougher regulations by the American Petroleum Institute.

"There are numerous additives that are formulated into the oil. Those include detergents; those include anti-wear additives, antioxidants and dispersants. These different additives all have different functions," said Dustin Willhite, BG director of technology.

These changes have brought about many different oil types, such as semi-synthetic or full-synthetic. The way you know what's best for your car is a combination of letters and numbers, which are clearly stated in all owners' manuals.

In the small print, some manufacturers require a specific brand of oil be used.

"Basically, you have to use that manufacturer's oil, or else they void your warranty," Smith said.

Let's talk price. Is it true that you get what you pay for? In most cases, yes.

“All the oil manufacturers have to meet a standard for oil but they can meet a minimum standard or, if their oil's more expensive, they could increase their additive package because that's the most expensive part of the oil,” said Fuel Engineer, Richard Augustus.

In fact, the better the additive package in oil the longer you can go without a change. So in the long run, it could actually save you money.

And the science behind these additives is nothing to sneeze at.

The best advice? Do your homework. Know what your car needs and be diligent with your maintenance. It's a small price to pay to keep your engine clean and your wallet full.

Experts Query Use of Rice Additives

In China, Some food safety experts have expressed doubts about the use of additives in rice, although officials said they are free from potential safety hazards.



In response to media reports questioning the revised National Standard for Food Additives, the Ministry of Health issued a statement on Saturday, saying two additives - sodium diacetate and chitosan - were permissible for rice, and that a thickening agent - sodium starch phosphate - can be used in some rice products, such as rice noodles.

In the statement, Wang Zhutian, deputy director of the Fortified Food Office (FFO) under the Chinese Center for Disease Control and Prevention, said sodium diacetate is a widely used preservative in grain, rice and pastry, and chitosan is a coating agent used in rice. Both can help retain freshness and prevent mildew.

The revised regulation, issued early this month, comes into force on June 20.

"The two additives were allowed in rice before 2007, and they passed the safety assessment," Chen Junshi, director of the office, told China Daily on Sunday.

However, some food experts warned that using additives in rice might put food safety at risk, Beijing News reported on Friday.

One expert who wished to remain anonymous was less convinced.

"Rice is a staple food in China as well as a major ingredient for other food products. We must treat the use of rice additives with great caution," the expert was quoted by the newspaper as saying.

Other experts also questioned the need for additives in rice.

"According to the standards for using additives, a substance is used when it is technically indispensable. If rice is rot-resistant without additives, they should not be added," said Sang Liwei, a food-safety lawyer and the China representative of the NGO Global Food Safety Forum.

"I have worked in the grain industry for many years, but never heard of the practice of adding additives to rice during processing. There is no need," a technical veteran with the Food Research Institute of Guangdong province, surnamed Guo, was quoted on Saturday by Guangzhou-based Information Times as saying. According to Guo, there are two ways of packaging grain products in China to keep the rice fresh: vacuum packaging and aerating nitrogen into the packaging bags.

"It is easy, safe and inexpensive to retain the freshness of rice," Guo told the paper.

The revised national standard sought opinions from July to September last year, but officials said they did not receive any objections, so the additives were included on the final list.

"According to the procedure, if someone files an objection, the health department will examine and decide whether to exclude the additive," Chen said.

The standards can also be changed at any time if there are objections from the industry.

"If any rice manufacturer objected to the use of the additives, the health authority will take advice from other businesses and the industry, and make changes in the standard accordingly," Chen said.

Bloody Mary Preparation Recipe Open to The Public

[Guide] Bloody Mary is a low alcohol wine among cocktail, its bright red color together with a touch of salt savors, that make people feel a taste of a bloody existence. The reason why this cocktail is become so popular today, it is because in the West, Bloody Mary is a psychic game that very popular in young people, while in China, people usually go to bars, but very few people will try this cocktail.




2011 is the International Year of Chemistry. So scientists at the national meeting of the American Chemical Society in Anaheim raised a glass. (Or a beaker.) And they celebrated as only chemists can—by carefully analyzing its contents. [Neil Da Costa, "Flavor chemistry of the "Bloody Mary" cocktail"

The drink they dissected was the Bloody Mary, perhaps the world’s most chemically complex cocktail. A mix of tomato juice and vodka, along with lemon or lime, horseradish, Tabasco and Worcestershire sauces, black pepper and celery salt, the Bloody Mary packs a punch. And it lights up nearly our entire range of taste receptors, giving us sweet, salty, sour and savory.

To find out the Bloody Mary’s secret, researchers shared one with a chromatograph, which identified the various compounds that contribute to the drink’s flavor and bouquet. The scientists turned up plenty of antioxidants, as well as a few bartending tips.

First, make it fresh. The acids in tomato juice can degrade the drink’s other ingredients. Also, make it cold—ice slows the degradation. Use the best tomato juice --- the major source of flavor. But feel free to cheap out on the vodka. Its taste gets lost in the complex mix. In other words, chemists say to save the Grey Goose for other experiments.

Diesel Price Raise Link to 5% Bio-Additive

Last week, fuel and diesel prices on the European stock markets were relatively stable. Fuel prices increased to USD 1,115 (LVL 540) per ton, while diesel dropped to USD 1,050 (LVL 510) per ton, informs LETA.

But fuel stations have started to sell summer diesel, however, its price could grow due to the obligatory 5% bio-additive, which costs 43% more than fossil diesel, the Statoil Latvija spokesman, Kaspars Skrabans, informed the business information portal Nozare.lv.

The bio-additive currently costs slightly more than USD 1,500 (LVL 739).

Fuel and diesel prices are still affected by the political instability in Libya, the positive macroeconomic data in China and the United States as well as Russia's announcement that it could increase the export tax on oil products.
