Photosynthesis, pigment–protein complexes and electronic energy transport: simple models for complicated processes

Posted on 18. December, 2017.

Essentially all the accessible energy for life in the Earth’s biosphere is made available through the process of photosynthesis, the conversion of light energy from the Sun into storable chemical energy for metabolism. The process itself has been the subject of remarkable evolution throughout Earth’s history.

Biochar, soils and carbon capture

Posted on 24. October, 2012.

Could the creation of artificial terra preta assist sustainable agriculture, and possibly avert global warming? In his latest Current Commentary, Chris Rhodes considers the advantages of adding charcoal – “biochar” – to soil with the aim of recreating the properties of the dark earth. Biochar binds the essential nutrients N, P and K, and impedes dramatically the rate at which they are washed away by rain. Minute pores form in the charcoal which can hold more nutrients on its larger surface area and act as "condominiums" for microorganisms to grow in and so increases their density in the soil. However, to be effective, the biochar production process must produce more energy overall than it consumes.

DNA-binding transcription factors in prokaryotes

Posted on 24. October, 2012.

How organisms contend with environmental changes depend on their genes and ability to regulate their expression. DNA-binding transcription factors play a central role by regulating gene expression By considering the abundance of TFs in bacteria and archaea, the role of DNA-binding domains and their partner domains, and the effects of duplication events in the evolution of regulatory networks provides a comprehensive picture for how regulatory networks have evolved in prokaryotes.

Lithium-ion batteries on micro and nano scales

Posted on 24. October, 2012.

Lithium-ion batteries offer high energy density, flexibility, lightness in weight, design and longer lifespan than comparable battery technologies. A brief historical review of the development of Li-ion rechargeable batteries highlights the research strategies and the challenges of the synthesis, characterisation, electrochemical performance and safety of these systems. Moving from bulk materials to the nanoscale can significantly change electrode and electrolyte properties and consequently their performance in devices for energy storage and conversion.

Disruptive technology of additive manufacturing

Posted on 24. October, 2012.

Additive manufacturing could radically change the way in which many products are made and distributed. It fabricates components directly from 3D computer models by selectively depositing, curing, or consolidating materials one layer upon the next. It has state of the art applications. Additive manufacturing is already a valuable tool for surgeons to better understand unique, intricate anatomical relationships that are difficult to visualise using two-dimensional images.

Robert Hooke, polymath and flights of fancy

Posted on 24. October, 2012.

Robin Rowbury, in his final article for Science Progress, paid tribute to Robert Hooke in a series of “thumbnail sketches”. A polymath, Hooke was a gifted artist and scientist whose ideas were often pirated or under-rated.

Can Solar Fuels Avert A Petroleum Fuel Crisis?

Posted on 20. September, 2012.

The world population uses vast amounts of energy mainly obtained from fossil fuels. Renewable energy from all sources amounts to just above 1% of the total required. In his latest current commentary for Science Progress, Chris Rhodes shows how by capturing even a small amount of the solar radiation striking the top of the earth’s atmosphere, the imminent energy crisis could be averted and carbon emissions dramatically reduced.
