CO2 for a clean performance: Rheticus research project by Evonik and Siemens enters phase 2

High-value specialty chemicals produced from CO2 and water using electricity from renewable sources and bacteria

14-Oct-2019

Evonik and Siemens launched their joint research project Rheticus II. The goal is to develop an efficient and powerful test plant that will use carbon dioxide and water as well as electricity from renewable sources and bacteria to produce specialty chemicals (CO2). In the Rheticus I project, the ...

Bioplastics from Waste Fats

Using bacteria to replace plastics derived from fossil oil

25-Sep-2019

450 million tons of plastic are produced globally each year. PHAs represent a tentative approach to defeating the plague that is plastic. PHA stands for Polyhydroxyalkanoates. Polyhydroxyalkanoates are biopolymers and are referred to as bioplastics due to the similarity of their thermoplastic ...

Antiseptic resistance in bacteria could lead to next-gen plastics

Ancient protein pumps could be key to new green polymers

15-Aug-2019

The molecular machinery used by bacteria to resist chemicals designed to kill them could also help produce precursors for a new generation of nylon and other polymers, according to new research by scientists from Australia and the UK. "Resistance to artificial antiseptics appears to be a lucky ...

No chance for environment-relieving plastic decomposition by bacteria

Burst Hope

08-Aug-2019

No, they won’t help us with this particular environmental problem: Bacteria are definitely not able to decompose plastic released into marine environments, and they are unlikely to acquire this ability through evolution. This is the conclusion reached by microbiologists Sonja Oberbeckmann and ...

Actively Swimming Gold Nanoparticles

Chemotactic movement on the macroscale by a swarm of bacteria-mimicking nanoswimmers

07-Aug-2019

Bacteria can actively move towards a nutrient source—a phenomenon known as chemotaxis—and they can move collectively in a process known as swarming. Chinese scientists have redesigned collective chemotaxis by creating artificial model nanoswimmers from chemically and biochemically modified gold ...

'Semi-synthetic' bacteria churn out unnatural proteins

19-Jul-2019

Synthetic biologists seek to create new life with forms and functions not seen in nature. Although scientists are a long way from making a completely artificial life form, they have made semi-synthetic organisms that have an expanded genetic code, allowing them to produce never-before-seen ...

Will your future computer be made using bacteria?

Scientists are making graphene easier and more environmentally friendly to produce

12-Jul-2019

In order to create new and more efficient computers, medical devices, and other advanced technologies, researchers are turning to nanomaterials: materials manipulated on the scale of atoms or molecules that exhibit unique properties. Graphene--a flake of carbon as thin as a single later of ...

Methane-consuming bacteria could be the future of fuel

Discovery illuminates how bacteria turn methane gas into liquid methanol

13-May-2019

Known for their ability to remove methane from the environment and convert it into a usable fuel, methanotrophic bacteria have long fascinated researchers. But how, exactly, these bacteria naturally perform such a complex reaction has been a mystery. Now an interdisciplinary team at Northwestern ...

How to purify water with graphene

02-May-2019

Scientists from the National University of Science and Technology "MISIS" together with their colleagues from Derzhavin Tambov State University and Saratov Chernyshevsky State University have figured out that graphene is capable of purifying water, making it drinkable, without further ...

New sensor detects rare metals used in smartphones

25-Apr-2019

A more efficient and cost-effective way to detect lanthanides, the rare earth metals used in smartphones and other technologies, could be possible with a new protein-based sensor that changes its fluorescence when it binds to these metals. A team of researchers from Penn State developed the ...
