Un aérogel en graphène imprimé en 3D pour la nanoélectronique Une équipe de chercheurs du célèbre Lawrence Livermore National Laboratory a réalisé un aérogel en graphène qui pourrait avoir d'importantes applications en nanoélectroniques, notamment pour fabriquer des batteries et des capteurs. La nouveauté par rapport aux précédents matériaux de ce type est que celui-ci présente une structure plus ordonnée obtenue par impression 3D. Les chercheurs du Lawrence Livermore National Laboratory se sont illustrés plusieurs fois par des travaux sur l'aérogel. Cette mousse supporte plus de 2.000 fois son poids et constitue le solide le plus léger du monde. L'année dernière, les chercheurs du laboratoire Lawrence Livermore ont confectionné un aérogel à base de graphène et l'ont utilisé pour réaliser un supercondensateur. Le processus de fabrication de l'aérogel en graphène commence par la confection d'une encre à base d’oxyde de graphène en suspension dans l’eau et mélangé à de la silice.

Ask the Expert: Adding alternative energy to an existing home | Solar panels added to home Finding ways to add alternative energy to an existing home can be a challenge. And a challenge worthy of our ProudGreenHome experts. So we asked our Approved Contributing Experts, also known as ACE's, to tell us about the top challenges and solutions to adding alternative energy to a home. Ted Clifton, founder of Zero-Energy Plans LLC, and CVH Inc. When adding alternative energy sources to a home, I often find the biggest challenge to be that the original design either had the ridge running north to south, instead of east to west, or the roof was so littered with dormers, plumbing vents and other obstructions that there is no place on the south face of the roof to install a solar hot water heater or photovoltaic (PV) panels. The only solution to this is some kind of a ground-based system, like a rotating array on a pedestal, or mounting the system on a garage or garden shed. The second challenge is somewhat related to the first, but more difficult to deal with.

Insulation - Lowimpact.orgLow impact living info, training, products & services What is it? It is any material that slows down the rate at which heat is lost through the fabric of your building (although it can also mean sound or fire insulation, or keeping heat out, this factsheet is about keeping heat in). Air is actually the insulator, and the material is a way of trapping air. For example, you may sleep under a duvet containing eider (duck) feathers. Installing internal wall insulation. Houses had solid walls until the 1920s, when they started to be built with two walls with a cavity in between. k-values, R-values and U-values The insulation properties of a material can be expressed by its k-value. Some building materials are themselves very insulating, such as hempcrete – here being used to insulate a roof; and straw bale walls have an exceptionally good U-value (0.13). What are the benefits? It will reduce the amount of heat you need to generate, and therefore save energy, along with the associated pollutants and emissions. What can I do?

Aérogel Il a été créé par Steven Kistler en 1931, lors d'un pari avec Charles Learned de la forme : « Qui pourrait remplacer le liquide à l'intérieur d'un bocal de gel, par du gaz, sans qu'il se rétracte ? »[1]. Les travaux de Kistler l'ont amené à composer des aérogels de silice, d'alumine, d'oxyde de chrome(III) ou d'oxyde d'étain. Des aérogels composés de carbone ont été inventés au début des années 1990. Caractéristiques[modifier | modifier le code] Une démonstration des capacités isolantes de l'aérogel. L'aérogel est composé jusqu'à 99,8 % d'air avec un rapport masse de solide / volume de l'aérogel pouvant descendre à 0,16 mg/cm3, ce qui en faisait le solide le plus léger connu encore récemment (micro-lattice, aérographite). L'aérogel est un isolant remarquable, car il stoppe presque complètement trois méthodes de propagation de chaleur (la conduction thermique, la radiation thermique et la convection). À cause de sa nature hygroscopique, l'aérogel est sec au toucher et il assèche.

Webshop Wohnwagon | Die Dämmstoff-Parade! Wir stellen vor… Willkommen bei der Parade! Heut machen die verschiedensten Dämmstoffe ihre Aufwartung. Dämmplatten, Wolle, Verbunddämmstoffe, eingeblasene, geschüttet, gestopfte – eine bunte Mischung! Jeder Dämmstoff hat andere Stärken und Schwächen, manche eignen sich besser für Türen & Fenster, andere für erdberührte Zonen. Im heutigen Blog sind viele Dämmstoffe an der Reihe. So, da marschieren sie auch schon auf! Schaumglas – Schaumkrone kennen wir, aber was ist Schaumglas? Schaumglas ist Glas das mit Treibmitteln und hoher Temperatur aufgeschäumt wird. Schaumglas hat eine Dämmwirkung von λ = 0,038 W/mK (was das heißt erklären wir in unserem letzten Blog – schau rein!) Perlit – Keine Angst das kauft man nicht beim Juwelier Perlit ist ein Vulkanisches Gestein und wird auch gerne als Naturglas bezeichnet. λ ≈ 0.050 W/mK Vulkanischer Perlit ist als Rohstoff weltweit in ausreichendem Maße vorhanden, aber nicht regional. Die Produktion ist gleich wie beim Blähton sehr energieaufwendig. Was Kork kann: Links

Cómo fabricar aerogel: 25 pasos 3 partes:Construye el secador supercríticoPrepara aerogel de síliceInstrucciones de secado alternativas – secado subcrítico El aerogel es un material ultra liviano con una densidad muy baja y muy poca conductividad térmica. Es bastante traslúcido; sin embargo, tiene una textura áspera al tacto. Tradicionalmente, el aerogel se fabrica con un proceso de secado supercrítico, así que deberás construir en tu casa tu propio secador supercrítico si quieres fabricar este material por tu cuenta. Existen algunas variedades que se pueden fabricar sin un secador supercrítico, pero tienden a ser más sensibles y más densas.

EcoSeal Take comfort in knowing your home is sealed tight. Together, EcoSeal and Knauf Insulation EcoBatt® or premium blowing wool make up the Knauf Insulation EcoSeal® System, your best option for total energy efficiency in your home. Energy efficiency Comfort andPeace of Mind Sustainability Close The Best Insulation Types for Your Home Installing insulation is one of the most environmentally friendly things a homeowner can do. About 65 percent of U.S. houses are poorly insulated, a 2005 Harvard study estimates. Fortunately, you can cut heating and cooling bills by about 30 percent with proper insulation. These days, insulation is made with everything from newspaper and sheep's wool to cotton and chemical foams. Many are far more "green" than their predecessors-including formaldehyde-free and recycled-content insulation. Even fiberglass, that old standard, has improved environmentally. When choosing insulation, most homeowners contemplate R-value, which measures resistance to heat flow. A federal energy tax credit can help homeowners recoup their insulation investment if they complete the improvements by the end of 2007. Fiberglass insulation: The pink stuff Foam insulation Spray foam insulation is an effective insulator with an R-value that ranges from about 3.2 to 7 per inch. Cotton insulation Cellulose insulation 1. 2.
