Ocean sink for man-made CO2 measured

18-Mar-2019

An international research project led by scientists from ETH Zurich has determined the amount of man-made CO2 emissions taken up by the ocean between 1994 and 2007. Not all of the CO2 generated during the combustion of fossil fuels remains in the atmosphere and contributes to global warming. The ...

Capturing carbon directly from the air – that has a future

Study analyzes energy requirements for negative emissions technologies

06-Mar-2019

Using special filters to remove the greenhouse gas carbon dioxide (CO2) directly from the air could be the best way to generate so-called negative emissions, at the scale of many billions of tons of CO2 per year throughout the world by 2050. “Direct Air Capture” has many characteristics that can ...

New molecular blueprint advances our understanding of photosynthesis

Shedding light on the process by which plants convert carbon dioxide into sugar

19-Feb-2019

Researchers at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have used one of the most advanced microscopes in the world to reveal the structure of a large protein complex crucial to photosynthesis, the process by which plants convert sunlight into cellular ...

Adding a porous envelope to aluminum plasmonics

Gas-trapping framework married to light-powered nanocatalysts

13-Feb-2019

When Rice University chemist and engineer Hossein Robatjazi set out to marry a molecular sieve called MOF to a plasmonic aluminum nanoparticle two years ago, he never imagined the key would be the same process nature uses to petrify wood. In a new paper Robatjazi and co-authors with Rice's ...

'Flipped' metal oxide cage can sort CO2 from CO

Spherical vanadium oxide clusters that can trap and hold carbon dioxide

10-Jan-2019

How do you separate carbon dioxide from carbon monoxide? One way, showcased by a new study from Kanazawa University, is to use a bowl of vanadium. More precisely, a hollow, spherical cluster of vanadate molecules can discriminate between CO and CO2, allowing potential uses in CO2 storage and ...

Powder could help cut CO2 emissions

20-Dec-2018

Scientists at the University of Waterloo have created a powder that can capture CO2 from factories and power plants. The powder, created in the lab of Zhongwei Chen, a chemical engineering professor at Waterloo, can filter and remove CO2 at facilities powered by fossil fuels before it is released ...

Almirall builds the largest self-consumption photovoltaic plant in Catalonia

Generating 1,200 MWh per year, avoiding more than 479 tons of CO2

29-Nov-2018

Almirall, S.A has completed the construction of an innovative 800 kWp photovoltaic plant, located in its pharmaceutical plant in Sant Andreu de la Barca (Barcelona), which aims to save 12% of the electrical energy consumption from the site. This initiative is part of the company's policy to ...

How to convert climate-changing carbon dioxide into plastics and other products

Scientists develop green chemistry based on a natural process

23-Nov-2018

Rutgers scientists have developed catalysts that can convert carbon dioxide - the main cause of global warming - into plastics, fabrics, resins and other products. The electrocatalysts are the first materials, aside from enzymes, that can turn carbon dioxide and water into carbon building blocks ...

Sustainable 'nano-raspberry' to neutralize poisonous carbon monoxide

22-Nov-2018

Scientists from the Nagoya Institute of Technology (NITech) in Japan have developed a sustainable method to neutralize carbon monoxide, the odorless poison produced by cars and home boilers. Traditionally, carbon monoxide needs a noble metal - a rare and expensive ingredient - to convert into ...

Carbon fibers from greenhouse gas

How algae could sustainably reduce the carbon dioxide concentration in the atmosphere

16-Nov-2018

In collaboration with fellow researchers, chemists at the Technical University of Munich (TUM) have developed a process that, according to initial calculations, can facilitate economically removing the greenhouse gas carbon dioxide from the atmosphere. The latest World Climate Report (IPCC ...
