Solution to “Legionella”

15.09.2005


As a result of the joint working between teams of experts from the Iberia Ashland Chemical, S.A. company and the INASMET-Tecnalia Technological Centre, a solution has been found to prevent the serious disease caused by the bacteria known as “Legionella” and other similar disorders.


SONOXIDE system



This achievement has meant a great advance for human health. It is based on the biocidal and bacteriostatic effect of the SONOXIDE system, used in refrigeration towers of factory buildings and installations that are prone to be the focus for the proliferation of Legionnaires’ disease.

In order to validate the system, the team of INASMET-Tecnalia experts designed a refrigeration tower simulation within a biologically-isolated laboratory (P2 level). A wide range of trials were carried out in this isolated and secure system in order to determine the efficacy thereof.


Regarding the technology developed, it consists of a system based on low-intensity, high-frequency ultrasounds which, together with the introduction of micro-bubbles of air, produce an effect of photo-sonoluminiscence. The concentration of ultrasounds by constructive interference generates a pressure front that produces a decompression of the gases dissolved in the water. This wave front produces a luminous plasma around the bubbles, as well as high pressure and temperatures.

These pressures and temperatures have two effects: on the one hand, they eliminate the circulating bacteria and, on the other, they generate an oxidative stress that is transmitted throughout the water refrigeration system. This stress, together with the continuous loss of circulating bacteria throughout the system, reduces the formation of biofilm even at extremely low levels – and maintains this to such an extent that the fixing of “legionella” bacteria or any other micro-organisms needing biofilm in order to grow in the system, is impeded.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
