Dousing Flames with Low-Frequency Sound Waves

A new type of extinguisher that uses sound waves to put out fires has been built by two engineering students in the US. Both chemical- and water-free, the invention offers a relatively non-destructive method of fire control, which could find applications in fighting small fires in the home, and the researchers now hold a preliminary patent application for their device.

While the concept of using sound waves to extinguish flames is not new, previous attempts to realize the principle – including efforts by teams at West Georgia University and the US Defense Advanced Research Projects Agency (DARPA) – had not been successful.

Undeterred by this, as well as initial [...]

Nanotechnology to the rescue: Replacing chemical disinfectants with engineered water nanostructures

The burden of foodborne diseases worldwide is huge, with serious economic and public health consequences. The CDC estimates that each year in the USA approximately 48 million people get sick, 128,000 get hospitalized and 3,000 die from the consumption of food contaminated with pathogenic microorganisms. The food industry is in search of effective intervention methods that can be applied from 'farm to fork' to ensure the safety of the food chain and be consumer and environment friendly at the same time. In the food industry, chemicals are routinely used to clean and disinfect product contact surfaces as well as the outer surface of the food itself. These chemicals provide a necessary and [...]
