‘The value of instant steam lies in creating truly portable steam that can be generated intermittently on demand,’ says Dave Wardle, business development director at Oxford Catalysts.
The company is already in talks with UK specialist steam supplier OspreyDeepclean about possible applications for steam cleaning hospitals, Wardle adds. An as-yet unpublished 2006 study at University College London Hospital, commissioned by OspreyDeepclean, showed that dry steam applied at temperatures ranging from 150 to 180 C could destroy bacteria, including MRSA and Clostridium difficile, in less than 2s, without the use of chemicals.
The new technology, devised by scientists at UK firm Oxford Catalysts, employs a precious metal catalyst to generate the steam at temperatures up to 800 C in just 1-2 seconds, at room temperature and pressure. Steam produced by the technology is so-called ‘dry’ steam, generated by the highly exothermic reaction between methanol and hydrogen peroxide. While too expensive to replace the vast quantities of steam used routinely by industry, a reaction chamber the size of a sugar cube can pump steam at a rate of 7L/minute at temperatures up to 800 C.
The first application is likely to be a GumBuster backpack for removing chewing gum from pavements and other surfaces. The patented GumBuster technology currently requires a minimum of 3kW of electrical power to generate the steam used by each operator and relies on generators carried on trolleys or vans. Use of the catalyst technology ‘will make the system more portable and make it possible to place the steam when we need it, where we need it,’ says Thomas Stuecken, chief commercial officer at Proventec, the parent company of OspreyDeepclean.
Other more speculative applications for the steam for powering rockets and cars, and to provide mobile and portable power generation, are currently being considered.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
