The “Safer Trucks” concept brings a valuable contribution to road safety and environment by improving three aspects: passive safety, aerodynamics and safety of vulnerable road users. EAA Automotive & Transport group has extensively worked with FKA (Forschungsgesellschaft Kraftfahrwesen Aachen) on a design concept for crash boxes (or “Crash Management System”) at the front of trucks’ cabin that would absorb energy in case of a frontal crash with a vehicle. 03/16 > BE Suède 28 > Découverte d'un nouveau convertisseur catalytique pour le diesel. Energies & environnementDécouverte d'un nouveau convertisseur catalytique pour le diesel La consommation croissante de diesel, au détriment de l'essence, nécessite de mettre au point un nouveau processus de fabrication du diesel.

03/16 > BE Suède 28 > Découverte d'un nouveau convertisseur catalytique pour le diesel

Des chercheurs de l'Université de Stockholm en Suède et de l'Université polytechnique de Valence en Espagne ont découvert un nouveau matériau poreux présentant des propriétés uniques pour convertir la gazoline en diesel. L'aluminosilicate, appelé ITQ-39, appartient à la classe des zéolites regroupant des minéraux naturels et synthétiques ayant une structure cristalline ouverte. ITQ-39 a été produit par une équipe de recherche de l'Université polytechnique de Valence, dirigée par le professeur Avelino Corma. 06/14 > BE Allemagne 575 > Des amortisseurs de vibrations actifs à base d'élastomère. MatériauxDes amortisseurs de vibrations actifs à base d'élastomère En raison de leurs propriétés (faible rigidité, résistance à de hautes déformations, élasticité), les élastomères sont très utilisés dans les amortisseurs de vibrations.

Jusqu'alors, ils agissaient de manière passive au sein des amortisseurs, c'est à dire sans aucune intervention extérieure supplémentaire et sans apport extérieur d'énergie. Or, l'amortissement des vibrations serait plus efficace si les élastomères pouvaient réagir de manière active aux vibrations, c'est-à-dire en annulant ces dernières en leur superposant une excitation "inverse". 06/18 > BE Norvège 109 > L'aimant le plus puissant du monde.

Des travaux de recherche sur les matériaux magnétiques sont conduits depuis plus de 50 ans sur le site de l'IFE. L'aimant, décrit comme un produit dérivé du réacteur nucléaire de recherche JEEP II [2] de Kjeller, est d'ores et déjà breveté au Japon, en Russie et au Canada, et bientôt aux Etats-Unis et en Corée du Sud. 06/14 > BE Allemagne 575 > Capacité de décharge de 900 mAh/g pour des batteries lithium-soufre. ElectromobilitéCapacité de décharge de 900 mAh/g pour des batteries lithium-soufre L'utilisation du soufre en tant que matériau pour cathode de batterie repose sur de nombreux avantages : densités énergétiques élevées, non-toxicité, coût peu élevé et réserves disponibles en grande quantité.

New electrode material could lead to rechargeable sodium batteries. A new electrode material could help make lightweight, powerful rechargeable sodium batteries to replace lithium-ion batteries used in electronics and some electric vehicles.

New electrode material could lead to rechargeable sodium batteries

The material contains widely available iron, instead of the nickel and cobalt commonly used in these electrodes, and enables a similar energy density to electrodes in lithium batteries. Sodium is an attractive candidate to replace lithium in batteries because it’s cheaper and widely available around the world. But building a sodium battery requires redesigning battery technology to accommodate the chemical reactivity and larger size of sodium atoms.

Mine to Magnet. Richard (Rick) Mills Ahead of the Herd As a general rule, the most successful man in life is the man who has the best information The rare earths are a group of 17 elements comprising Scandium, Yttrium, and the Lanthanides.

Mine to Magnet

The Lanthanides are a group of 15 (Cerium, Dysprosium, Erbium, Europium, Gadolinium, Holmium, Lanthanum, Lutetium, Neodymium, Praseodymium, Samarium, Terbium, Thorium, Thulium, Ytterbium) chemically similar elements with atomic numbers 57 through 71, inclusive. Yttrium, atomic number 39, isn’t a lanthanide but is included in the rare earths because it often occurs with them in nature - it has similar chemical properties.

Scandium, atomic number 21 is also included in the group although it usually occurs only in minor amounts. Rare Earths from Mine to Magnet. The rare earths are a group of 17 elements comprising scandium, yttrium and the lanthanides.

The lanthanides are a group of 15 (cerium, dysprosium, erbium, europium, gadolinium, holmium, lanthanum, lutetium, neodymium, praseodymium, samarium, terbium, thorium, hulium, ytterbium) chemically similar elements with atomic numbers 57 through 71, inclusive. Yttrium, atomic number 39, isn't a lanthanide but is included in the rare earths because it often occurs with them in nature - it has similar chemical properties. Scandium, atomic number 21 is also included in the group although it usually occurs only in minor amounts. Reality Check: First Solar and Tellurium. Is there enough Tellurium to meet the future needs of First Solar (FSLR) and other thin-film CdTe solar sell producers? The answer is crucial to long-term investors in FSLR who are looking at a P/E over 100. With a market capitalization of $16 billion and a likely future profit of $1 per peak watt ($1/Wp), FSLR needs to produce 1 GWp per quarter to have a P/E of 18. Old research from 2000 (and still being referenced as a 2006 Hoffman article) claims there's enough Te for 20 GWp/yr.

Newer 2005 research says otherwise. FSLR expects to produce 0.380 GWp in 2008 which will use only 10% or 20% of the world's 200 to 400 tonnes/yr Tellurium production ( 100 tonnes Te per 1 GWp is required for a 3 micron thickness). Plusieurs technologies ''vertes'' vont pâtir de tensions sur l'approvisionnement en matières minérales rares. Une liste de quatorze matières minérales critiques a été publiée jeudi 17 juin par la Commission européenne. Difficilement substituables et produites dans quelques pays, elles sont vitales pour plusieurs technologies environnementales. Antimoine, béryllium, cobalt, spath fluor, gallium, germanium, graphite, indium, magnésium, niobium, métaux du groupe du platine, terres rares, tantale et tungstène : ce sont les 14 matières premières (sur les 41 analysées) désormais considérées comme ''critiques'' en termes d'approvisionnement par la Commission européenne, selon une communication de l'exécutif européen publiée jeudi 17 juin.

Graphite: Supply and Demand | MiningFeeds.com. A magnified image of large flake graphite using an electron microscope. In 2010 a European Commission included graphite among the 14 materials it considered high in both economic importance and supply risk. The British Geological Survey listed graphite as one of the materials to most likely be in short supply globally. The US has also declared graphite a critical material. The U.S. Department of Homeland Security, and the State Department, said America could be hurt if terrorists were to disable graphite mines in China. Graphite: Pencil It In. As a general rule, the most successful man in life is the man who has the best information Sometime between 1500 and 1565 a large graphite deposit was discovered in Cumbria, England.

Because the graphite was extremely pure and solid it could easily be sawed into sticks. The graphite was actually thought to be a form of lead and called plumbago – Latin for lead ore. The Borrowable Mine was soon ordered to be put under armed guard by Queen Elizabeth because the “lead” could be used to line the moulds for making her armies cannonballs. But black marketers managed to smuggle out the graphite for continued use in pencils. Graphite. The mineral / ˈ ɡ r æ f aɪ t / is an allotrope of carbon . It was named by Abraham Gottlob Werner in 1789 from the Ancient Greek γράφω ( ), "to draw/write", [ 4 ] for its use in pencils , where it is commonly called (not to be confused with the metallic element lead ).

Unlike diamond (another carbon allotrope), graphite is an electrical conductor , a semimetal . Carbon nanotube. Allotropes of carbon. Graphene.
