Researchers Use E.coli to Engineer Improved Biofuels

Posted by in categories: engineering, sustainability

Interesting.


Although E. coli bacteria is often considered as a bad bug, laboratory-adapted E. coli that do not harm human beings and can multiply fast have been commonly used for various research purposes.

The same property allows the bacteria to rebuild into the smallest of factories when their chemical producing ability is utilized. E. coli possesses the ability to crank out pharmaceuticals, biofuels, and various other useful products.

How to turn green light blue

Posted by in categories: solar power, sustainability

The upconversion of photons allows for a more efficient use of light: Two photons are converted into a single photon having higher energy. Researchers at KIT now showed for the first time that the inner interfaces between surface-mounted metal-organic frameworks (SURMOFs) are suited perfectly for this purpose — they turned green light blue. The result, which is now being published in Advanced Materials (“Photon Upconversion at Crystalline Organic–Organic Heterojunctions”), opens up new opportunities for optoelectronic applications such as solar cells or LEDs.

With new water generators, Carrollton startup can unlock the ocean above your head

Posted by in categories: solar power, sustainability

In the blackland prairie of Texas, an ocean is thousands of miles away. But Benjamin Blumenthal, co-founder and chief executive officer of SunToWater Technologies, says we’re all standing under the sixth ocean — the one that’s above our heads.

The Carrollton startup makes an appliance that unlocks that water supply. The company’s water generators — each about the size of a central air conditioning unit — use air, salt and solar power to produce gallons of drinkable water. They could bring water to rural communities without a municipal water supply, regions stricken by drought or developing countries with water contamination.

But the company will target a higher-end market first: Homeowners with large lawns to water and swimming pools to fill. Blumenthal said SunToWater is focusing on customers in California and Texas, two states that have coped with an unpredictable, and often limited, water supply and the water restrictions and high utility bills that come with it.

Engineering a better biofuel

Posted by in categories: engineering, sustainability

The often-maligned E. coli bacteria has powerhouse potential: in the lab, it has the ability to crank out fuels, pharmaceuticals and other useful products at a rapid rate. A research team has discovered a new way to remove a major stumbling block in the process, and boost biofuel production from E. coli.

New way to model molecules

Posted by in categories: biological, chemistry, computing, encryption, quantum physics, robotics/AI, solar power, sustainability

Magine a future in which hyper-efficient solar panels provide renewable sources of energy, improved water filters quickly remove toxins from drinking water, and the air is scrubbed clean of pollution and greenhouse gases. That could become a reality with the right molecules and materials.

Scientists from Harvard and Google have taken a major step toward making the search for those molecules easier, demonstrating for the first time that a quantum computer could be used to model the electron interactions in a complex molecule. The work is described in a new paper published in the journal Physical Review X by Professor Alán Aspuru-Guzik from the Department of Chemistry and Chemical Biology and several co-authors.

“There are a number of applications that a quantum computer would be useful for: cryptography, machine learning, and certain number-theory problems,” Aspuru-Guzik said. “But one that has always been mentioned, even from the first conceptions of a quantum computer, was to use it to simulate matter. In this case, we use it to simulate chemistry.”
