Scientists at the Institute of Process Engineering (IPE) at the Chinese Academy of Sciences in Beijing and Yangzhou University (YZU) in Jiangsu have developed an effective and energy-efficient technique for purifying water by using graphitic carbon nitride sheets.

Their prototype, presented February 7 in the journal Chem, purified pathogen-rich water in 30 min, killing over 99.9999% of … [more…]

TULSA — A Tulsa teen making major strides in cleaning our rivers and streams is now getting global recognition for his advancements in environmental engineering.

"Seeing what will make an impact on the world really drives me forward," said Braden Milford, senior at Cascia Hall.

Braden created a water purification system right in his Cascia Hall classroom.

"My project associates environmentally extracted bacteria with algae in a jelly-like system that

Mere sunlight can be used to eradicate pollutants in water

Chemists present new process to produce hydrated electrons — ScienceDaily

Advances in environmental technology: You don’t need complex filters and laser systems to destroy persistent pollutants in water. Chemists have developed a new process that works using mere sunlight. The process is so simple that it can even be conducted outdoors under the most basic conditions.

A hiker gets disoriented while on a desert trek when she comes upon a drying puddle left by a recent rain. Consumed by thirst, miles from home, the hiker must decide whether to drink and risk infection from whatever bacteria are in the puddle, or endure dehydration.

But that hiker might one day be able to drink worry free, thanks to a new kind of water

When you think about the English computer scientist Alan Turing you most probably think of either his code-breaking efforts at Bletchley Park during World War II or his early hypotheses about artificial intelligence, which resulted in the formulation of the famous Turing Test.

Something you probably don’t associate him with? Groundbreaking chemistry — and, more specifically, groundbreaking chemistry which could soon be used to provide people around the world with
