Nano Device Based on AcrB Protein Offers Solar-Powered Water Filtering

A new nano-filter powered by sunlight can clean large bodies of water from antibiotics and carcinogens. The device, developed by the University of Cincinnati, is much more effective than the activated carbon that’s currently being used for this purpose. Two bacterial proteins absorb about 64 percent of the antibiotics in surface water. For a comparison, [...]

Perforene: A Graphene Water Filter 100 Times More Efficient

True, the technology is a couple years away, but graphene-based Perforene developed by Lockheed could revolutionize desalinization and water purification. Lack of freshwater is becoming an increasingly desperate situation, typical desalinization is energy intensive and expensive, but a graphene water filter could be 100x more efficient. Graphene, a nanoscale material made up of pure carbon, [...]

Lima, Perú – Freshwater From a Billboard, University of Engineering and Technology

If there’s one thing that mars a skyline worse than a building in front of your favorite mountaintop, it’s probably a billboard. Of course, a billboard is put there in your face for exactly that reason, so you take notice of it. In Lima, Perú, the University of Engineering and Technology [UTEC] has re-imagined the [...]

Toxins Removed from Water by New Metal-Organic Framework

A new Metal Organic Framework (MOF) may have the ability to filter environmental toxins out of water, thanks to a team of scientists at Monash University at CSIRO who developed it. MOFs are comprised of clusters of atoms that are connected by organic molecules. MOFs have identically sized pores, making it very easy to capture and [...]

Chlorinator Water Treatment System for Developing Countries Developed by GE Engineer

One of the most basic human needs is clean drinking water, which for millions of people in developing countries is simply not available. Without access to clean water, the population is vulnerable to water-borne diseases, something as simple as dysentery killing thousands every year. Unfortunately, getting clean water to these people is often expensive and [...]

Graphene Oxide Offers New Hope for Water Decontamination

Water is the universal solvent on the planet, and without it, minerals and nutrients can’t be transported. Life would cease to exist. This property of water, though, means it also transports and disperses toxins just as easily, including radioactive materials. Cleanup around nuclear sites, such as the recent disaster at the Fukushima Daiichi nuclear power [...]

14 Year-Old Invents Cheap Solar Powered Water Purification System

As teenagers, most of us cared more about say, a humiliating acne outbreak or which classmate we’d ask to homecoming, rather than the difficulties of developing countries. When she watched some Indian children drinking from a pool of stagnant water, Deepika Kurup, a 14-year-old living in Nashua, New Hampshire made it her goal to help [...]

Phosphine-Functionalized Resins Capturing Gold From Wastewater

The extraction of toxic but valuable metals such as nickel, chromium, lead, and mercury, from wastewaters produced in various industries such as semiconductor and mining has been a serious challenge to these industries. Unlike the commonly used ion-exchange resins that bind with metals unspecifically, a newly developed phosphine-functionalized resins bind with metals selectively via coordination [...]

A Novel Water Treatment Method Using Simple Electrochemistry

Various water treatment systems have sprung up to increase the quality of drinking water. For remote and underdeveloped areas, unfortunately, these technologies are not within reach. This situation led two chemists to a simple, yet brilliant idea to transform bore water into a potable one. Through electrochemistry, Dr. Hilary Nath and Associate Professor Alan Langdon [...]
