‘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 An as-yet unpublished 2006 study at University College London Hospital, commissioned by OspreyDeepclean, showed that dry steam applied at temperatures ranging from 150 to 180 C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.

Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal “Nature Communications” together with their colleagues from ETH Zurich.
Electronic components are becoming smaller and smaller. Components measuring just a few nanometers – the size of around ten atoms – are already being produced...

On Tuesday, 19 May 2015 the research icebreaker Polarstern will leave its home port in Bremerhaven, setting a course for the Arctic. Led by Dr Ilka Peeken from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) a team of 53 researchers from 11 countries will investigate the effects of climate change in the Arctic, from the surface ice floes down to the seafloor.
RV Polarstern will enter the sea-ice zone north of Spitsbergen. Covering two shallow regions on their way to deeper waters, the scientists on board will focus...
Nanoengineers at the University of California, San Diego developed a gel filled with toxin-absorbing nanosponges that could lead to an effective treatment for skin and wound infections caused by MRSA (methicillin-resistant Staphylococcus aureus), an antibiotic-resistant bacteria. This "nanosponge-hydrogel" minimized the growth of skin lesions on mice infected with MRSA - without the use of antibiotics. The researchers recently published their findings online in Advanced Materials.
To make the nanosponge-hydrogel, the team mixed nanosponges, which are nanoparticles that absorb dangerous toxins produced by MRSA, E. coli and other...
