New Instant Water Disinfectant Far More Effective Than Commercial Methods

New Instant Water Disinfectant 'Millions of Times More Effective' Than Commercial Methods

The creators of a new instant water disinfectant, made using only hydrogen and the surrounding air, claim their invention is "millions of times more effective" at ridding water of viruses and bacteria than commercial purification methods. In addition to revolutionizing municipal water cleaning, the inventors of the novel technique suggest their disinfectant can help safely and cheaply deliver potable water to communities in need.

Around the world, an estimated 780 million people are without reliable access to clean water, and millions more experience water scarcity at least once a month.

The technique — described Thursday in the journal Nature Catalyst — uses a catalyst of gold and palladium to instantly turn hydrogen and oxygen into hydrogen peroxide, a common disinfectant... The new disinfectant, which can be made and used on site, eliminates the safety issues associated with commercial hydrogen peroxide and chlorine purification methods. In lab tests, researchers found their catalyst yielded not only hydrogen peroxide, but a variety of highly reactive compounds called reactive oxygen species, or ROS. It turned out that these novel compounds were responsible for the majority of the new disinfectant's impressive antibacterial and antiviral abilities...

When compared to commercially produced hydrogen peroxide, scientists found their instant disinfectant was 10 million times more potent against viruses and bacteria.

Nanofiber Membrane Filters 99.9% of Salt From Seawater Within Minutes

Nanofiber Membrane Filters 99.9% of Salt From Seawater Within Minutes (interestingengineering.com)

A team of Korean scientists may have found a way to desalinate seawater in minutes. An anonymous reader quotes a report from Interesting Engineering: When using membranes to filter seawater, the membrane must remain dry for long periods of time. If the membrane becomes wet, the filtration process becomes ineffective and allows large amounts of salt to pass through the membrane. For long term operations, progressive membrane wetting has been observed regularly, which be resolved by changing the membrane. Researcher Yunchul Woo and his team at the Korea Institute of Civil Engineering and Building Technology (KICT) have now developed a membrane that is less susceptible to wetting and is stable in the long term.

The membrane is made of nanofibers that have been fabricated into a three-dimensional hierarchical structure, This was achieved by using a type of nanotechnology called electrospinning. Using this technology, the researchers were able to fabricate a membrane that is highly hydrophobic -- i.e. water repellent. The hydrophobic nature of the membrane is helpful because it is designed to not allow water molecules to pass. Instead, a temperature difference is applied on the two sides of the membrane that causes water from one end to evaporate into water vapor. The membrane allows water vapor to pass, which then condenses onto the cooler side. Called, membrane distillation, this is a commonly used method of desalination using membranes. Since the salt particles are not converted to the gaseous state, they are left out on one side of the membrane, giving highly purified water on the other side. The Korean researchers also used silica aerogel in their membrane fabrication process which further enhanced the flow of water vapor through the membrane, providing quicker access to desalinated water. The team tested their technology for continuous operation for 30 days and found that the membrane continued to filter out 99.9 percent salt without any wetting issues.
The study has been published in the Journal of Membrane Science.

The factory of the future, batteries not included

Many analysts have predicted an explosion in the number of industrial “internet of things” (IoT) devices that will come online over the next decade. Sensors play a big role in those forecasts. Unfortunately, sensors come with their own drawbacks, many of which are due to the limited energy supply and finite lifetime of their batteries. […]

New Energy-Dense Battery Could Enable Long-Distance Electric Cars...

"NATIONAL HARBOR, Md.—A company founded in the Palo Alto public library has taken a dose of government money and technology and turned it into the most energy-dense battery ever. Envia System's new lithium-ion battery packs roughly twice as much energy per gram as present batteries, the company will announce here at the third annual summit of the Advanced Research Projects Agency—Energy, (ARPA–e). 'We achieved 400 watt-hours per kilogram'"... http://www.scientificamerican.com/article.cfm?id=new-energy-dense-battery-could-enable-long-distance-electric-cars
