Metal powder: zero-carbon fuel for the future?

How iron can be used to store and transport energy

10-Oct-2022 - Gaining sustainable energy from wind, solar and water is commonly known and applied. However, renewable sources depend on environmental conditions: in peak times of wind and sun, excess energy is produced that is needed in times of less wind and sunshine. But how to store and transport this ...

Powder kit for more flexibility and material diversity in 3D printing

27-Jul-2022 - Powder-based laser beam melting (LPPF) is probably the best-known AM process and has great potential for industrial applications. But how can the limited range of materials for this process be circumvented and the market potential further expanded? This question was addressed by the IWM of RWTH ...

An alternative low-cost technique to produce metal powders for 3D printing

08-Apr-2022 - Additive manufacturing (AM), also known as metal 3D printing, creates objects by addition of material, layer by layer. A major source material for AM is metal powder, which is predominantly produced using a technique calledatomisation, in which a molten metal stream is broken up into fine ...

3-D printed metals can be both - strong and ductile

12-Dec-2017 - A new technique by which to 3D print metals, involving a widely used stainless steel, has been show to achieve exception levels of both strength and ductility, when compared to counterparts from more conventional processes. The findings outline how a joint research team from the University of ...

New application of the selective laser melting method

13-Mar-2017 - Scientists of Peter the Great St. Petersburg Polytechnic University (SPbPU) and Delft University of Technology developed a technology for obtaining new metal structures by selective laser melting method (additive technology of manufacturing three-dimensional objects from metal powders). Due to ...

Harnessing the energy of fireworks for fuel

20-Jan-2017 - The world relies heavily on gasoline and other hydrocarbons to power its cars and trucks. In search of an alternative fuel type, some researchers are turning to the stuff of fireworks and explosives: metal powders. And now one team is reporting a method to produce a metal nanopowder fuel with ...

A new way to print 3-D metals and alloys

13-Jan-2016 - While current methods rely on vast metal powder beds and expensive lasers or electron beams, Northwestern's new technique uses liquid inks and common furnaces, resulting in a cheaper, faster, and more uniform process. The Northwestern team also demonstrated that the new method works for an ...

Could metal particles be the clean fuel of the future?

11-Dec-2015 - Metal powders, produced using clean primary energy sources, could provide a more viable long-term replacement for fossil fuels than other widely discussed alternatives, such as hydrogen, biofuels or batteries. "Technologies to generate clean electricity - primarily solar and wind power - are ...

Short Laser Pulses for Material Deposition with Cold Spray Technology

17-Apr-2015 - In a new EU-funded project, ultra-short laser pulses modify material surfaces so that metal powder from a cold gas jet can adhere more easily. With Cold Spray Technology, coating lightweight materials such as plastics or carbon fiber reinforced plastic (CFRP) becomes significantly simpler. The EU ...
