Longer life for bioelectrodes with oxygen-free environment

Longer life for bioelectrodes with oxygen-free environment

April 28, 2019 |

In Germany, a research team from Ruhr-Universität Bochum has shown that operation in an oxygen-free environment significantly prolongs the life of the bioelectrode. “In order to generate energy sustainably and efficiently, we must not only understand but also overcome the processes that limit the lifetime of renewable energy conversion technologies,” says Wolfgang Schuhmann. The use […]

Structure and function of photosynthetic protein explained

Structure and function of photosynthetic protein explained

January 19, 2019 |

In Germany, an international research team has elucidated the structure and mode of action of the photosynthetic complex I. The membrane protein complex plays an important role in the electron transport processes in photosynthesis. “The results close one of the last major knowledge gaps in the understanding of the photosynthetic electron transport pathways,” said the […]

Quest fulfilled? Holy Grail found? 40% crop yield increase really possible?

Quest fulfilled? Holy Grail found? 40% crop yield increase really possible?

January 19, 2019 |

Regardless of your age, you’ve probably heard of the search for the Holy Grail, or at the very least watched Monty Python’s movie, “Holy Grail.” And while everyone is probably searching for their own holy grail, scientists in Illinois may have just gotten incredibly close to finding the treasure that any crop producer has been […]

Researchers look at altering tools cyanobacteria use to capture light for photosynthesis

Researchers look at altering tools cyanobacteria use to capture light for photosynthesis

April 25, 2017 |

In Washington state, a recent study by researchers from the Environmental Molecular Sciences Laboratory and Washington University investigated effects of altering large cellular complexes called phycobilisomes, which cyanobacteria use to efficiently capture light energy for photosynthesis, to guide development of optimal strategies for biofuel production. The findings revealed changes to phycobilisome structure indirectly affect critical, […]

Japanese researchers make breakthrough in understanding photosynthesis

Japanese researchers make breakthrough in understanding photosynthesis

April 19, 2017 |

In Japan, photosynthesis requires a mechanism to produce large amounts of chemical energy without losing the oxidative power needed to break down water. A Japanese research team led by the Kobe University has clarified part of this mechanism, marking another step towards the potential development of artificial photosynthesis. The findings were published on February 27 […]

University of Copenhagen researchers discover reverse photosynthesis

University of Copenhagen researchers discover reverse photosynthesis

April 5, 2016 |

In Denmark, researchers at the University of Copenhagen have discovered a natural process they describe as reverse photosynthesis. In the process, the energy in solar rays breaks down, rather than builds plant material, as is the case with photosynthesis. The sunlight is collected by chlorophyll, the same molecule as used in photosynthesis. Combined with a […]

Berkeley Lab unveils system to mimic natural photosynthetic process

Berkeley Lab unveils system to mimic natural photosynthetic process

April 27, 2015 |

In California, a potentially game-changing breakthrough in artificial photosynthesis has been achieved with the development of a system that can capture carbon dioxide emissions before they are vented into the atmosphere and then, powered by solar energy, convert that carbon dioxide into valuable chemical products, including biodegradable plastics, pharmaceutical drugs and even liquid fuels. Scientists […]

Substance in Photosynthesis Was in Play in Ancient, Methane-Producing Microbes

Substance in Photosynthesis Was in Play in Ancient, Methane-Producing Microbes

February 19, 2014 |

In Virginia, researchers from Virginia Tech, Berkeley and other institutions have discovered that a process that turns on photosynthesis in plants likely developed on Earth in ancient microbes 2.5 billion years ago, long before oxygen became available. The research offers new perspective on evolutionary biology, microbiology, and the production of natural gas, and may shed […]

Biofuels’ 10 scariest challenges: Part 2 of 2

Biofuels’ 10 scariest challenges: Part 2 of 2

August 21, 2013 |

Upstream, downstream, processing, policy, finance – opportunities and challenges abound in the bioeconomy – but which challenges are the most intractable and daunting of them all? In today’s part 1, #5 through #1. They go via various aliases — naysayers, pessimists, The Party of No, doom-and-gloom’ers, realists, skeptics, and so on. For almost every aspect […]

Go Wet, Young Friend

April 3, 2013 |

As bio, solar and computing inaugurate a spectacular Age of Convergence — the long-term opportunities in energy may well lie at sea. One of the perplexities of our time: why solar systems are so photon-efficient and so troubled in energy storage; conversely, how biomass systems are so photon-inefficient yet have magnificently dense energy storage options […]
