#Materials and drives for High & Wide efficiency electric powertrains-Reducing dependency on rare earth materials Presently, drives for Fully Electric vehicles and Hybrid electric vehicles develop their highest efficiency of around 935%within a speed range of usually 1
Considering the resource distribution of rare-earth metals, European car manufactures have to face the problem of restrictive and vulnerable supply chains for rare earth metals
because they use a reduced amount of rare earth materials, the new electromotors will eliminate or simplify the mechanical gearbox normally associated with electric motors through so-called magnetic gears,
because it doesn contain rare earth materials and metals. Activated carbon can come from a variety of low cost, easily-available sources.
require Rare earth minerals and lack the efficiency to make such massive installations practical. The HCPVT system uses a large parabolic dish, made from a multitude of mirror facets,
which reclaims rare earth elements from recycled electronics to create other resources, and MIT team Belleds Technologies,
With minimal demand for these abundant rare earths, they are stockpiled. Finding widely marketable uses for these stockpiled materials makes the best use of all mining resources,
#Quick, easy and early diagnosis with rare earth ions Lack of oxygen in cells is an indicator of diseases as serious as cerebral haemorrhages, stroke and cancer.
The compound is based on rare earths emitting coloured light that vary in colour with the amount of oxygen present in the sample.
and we are getting pretty good at synthesizing the rare earth containing molecules. Before the year is out,
The novel oxygen sensitive molecule is built with two rare earths, so called lanthanides. One lanthanide, europium, emits a constant red signal.
#US licensing of new rare earth recycling approach A new rare earth recycling technology developed by the US Department of energy's Critical Materials Institute (CMI) has been licensed to US Rare earths,
organic solvents and neutral extractants to'selectively recover'up to 90%rare earths. Lab tests indicate a high success rate for recovering a'highly pure form'of neodymium
'Our single-step process to recover rare earth elements from scrap magnets is more environmentally friendly
dysprosium and praseodymium for growing the clean tech sector-including electric vehicles, according to Kevin Cassidy, ceo of US Rare earths, Inc I
and wind turbines--eliminates the use of one of the scarcest and costliest rare earth elements, dysprosium,
and instead uses cerium, the most abundant rare earth. The result, an alloy of neodymium, iron and boron co-doped with cerium and cobalt
The research was supported by the U s. Department of energy's ARPA-E REACT program (Advanced Research Projects Agency-Energy-Rare earth Alternatives in Critical Technologies) which develops cost-effective alternatives to rare earths,
The REACT projects identify low-cost and abundant replacement materials for rare earths while encouraging existing technologies to use them more efficiently l
Cytof employs a technique called mass spectrometry and rare earth metals instead of fluorescent compounds, so scientists can use about 40 markers (and up to 100 in the future).
hings like yttria or lutecia and and dope them with rare earth ions. NRL has transitioned both types of laser materials and applications to industry.
However that trend could be short-lived as key materials known as rare earth elements become more expensive.
Plus most of these lights are made with rare earth elements that are increasingly in demand for use in almost all other high-tech devices
The researchers designed a family of materials that don't include rare earths but instead are made out of copper iodide
palladium, or rare earth materials from near-Earth asteroids. Prominent billionaire backers include Hollywood director James cameron and Google executives Larry page and Eric Schmidt.
the company is starting with rare earths because they fetch much higher prices. Its first customer is the U s. government,
which needs rare earth metals for its stockpile of strategically valuable materials. Rare earth ore is mined in just a few places in the world,
and high costs and environmental challenges have prevented companies from processing rare earth ore to make metals domestically.
Infinium process addresses a specific part of metal production: transforming partially processed oresetal oxidesnto metals. This can be done by immersing the oxides in a bath of molten salt and running electricity through the mixture.
This month Infinium is starting up production using a machine that will produce half a ton of rare earth metals annually.
and separating rare earth oxides from other materials in the ore (other new processes are being developed to address those issuesee he Rare-Earth Crisis. But for metals such as aluminum and magnesium,
#Novel Magnetic nanoparticles Could be an Alternative to Rare earth Magnets Researchers at Virginia Commonwealth University have constructed a powerful novel magnetic material capable of decreasing the dependence of United states
and other countries on rare earth elements produced by China. The unique material is made up of nanoparticles comprising cobalt,
These magnetic properties were far better than those of permanent magnets which usually posses rare earth elements.
The challenge of producing powerful magnets without using rare earth elements is a crucial national issue as about 70 to 80%of the current rare earth materials are made in China.
Permanent magnets possessing rare earth metals are a significant component required in communications, electronics, and automobile sectors. They are used also in radars and other applications.
China, being the chief global supplier of rare earth elements, have imposed restrictions on their export, which is causing an international problem.
A new analysis of zircon minerals suggests that the field originated at least 4. 2 billion years ago a hop after the planet formed in the geological timeline,
For this new estimate, Tarduno and his team looked at tiny zircon gemstones in Western australia that date back to the earliest two eons in the planet's history the Archean and Hadean periods.
A substance called magnetite that lies within the zircon crystals contains information about the magnetic field record at the time the minerals cooled from their molten state a process that took over a billion years.

#Researchers synthesize magnetic nanoparticles that could offer alternative to Rare earth magnets Abstract: A team of scientists at Virginia Commonwealth University has synthesized a powerful new magnetic material that could reduce the dependence of the United states
and other nations on rare earth elements produced by China.""The discovery opens the pathway to systematically improving the new material to outperform the current permanent magnets,
the material exhibits magnetic properties that rival those of permanent magnets that generally contain rare earth elements.
The need to generate powerful magnets without rare earth elements is a strategic national problem as nearly 70 to 80 percent of the current rare earth materials are produced in China.
Permanent magnets, specifically those containing rare earth metals, are an important component used by the electronics, communications and automobile industries,
China is the main supplier of world rare earth demands and has tried to impose restrictions on their export,

Many existing flow batteries use expensive rare earth metals like vanadium. This new battery is modeled on photosynthesis and uses quinones
The team of physicists at ANU and the University of Otago stored quantum information in atoms of the rare earth element europium embedded in a crystal.
In contrast to the massive and energy-intensive industrial process currently used to separate rare earths, the Penn team method works nearly instantaneously at room temperature and uses standard laboratory equipment.
Further modification of the ligand could enable other rare earths in technology products, such as compact fluorescent light bulbs, to be recycled this way n
