New process could slash energy demands of fertilizer, nitrogen-based chemicals

Tue, 16 Jan 2018 14:43:18 EST ~ Nitrogen-based synthetic fertilizer forms the backbone of the world food supply, but its manufacture requires a tremendous amount of energy. Now, computer modeling points to a method that could drastically cut the energy needed by using sunlight in the manufacturing process. Find out more...

Magnetic liquids improve energy efficiency of buildings

Tue, 16 Jan 2018 09:36:54 EST ~ Climate protection and the reduction of carbon dioxide emissions have been on top of global development agendas. Accordingly, research and development projects have been conducted on national and international levels, which aim for the improvement of the CO2-footprint in diverse processes. Apart from particularly energy-intensive sectors of the industry, the building sector in particular is among the biggest CO2-emmitters: from residential homes, manufacturing facilities and storage depots to big commercial buildings, about 40 percent of the energy consumption within the EU are due to the heating, cooling, air conditioning and lighting of buildings.

Shale gas is one of the least sustainable ways to produce electricity, research finds

Tue, 16 Jan 2018 08:50:12 EST ~ Shale gas is one of least sustainable options for producing electricity, according to new research. Find out more...

Slow 'hot electrons' could improve solar cell efficiency

Tue, 16 Jan 2018 08:50:03 EST ~ Photons with energy higher than the 'band gap' of the semiconductor absorbing them give rise to what are known as hot electrons. The extra energy is lost very fast, as it is converted into heat so it does not contribute to the voltage. Researchers have now found a material in which these hot electrons retain their high energy levels for much longer. Find out more...

Solar fuels: better efficiency using microwires

Mon, 15 Jan 2018 12:16:41 EST ~ Researchers have made significant efficiency improvements to the technology used to generate solar fuels. This involves the direct conversion of energy from sunlight into a usable fuel (in this case, hydrogen). Using only earth-abundant materials, they developed the most efficient conversion method to date. The trick was to decouple the site where sunlight is captured from the site where the conversion reaction takes place. Find out more...

New application for acoustics helps estimate marine life populations

Mon, 15 Jan 2018 09:42:25 EST ~ Researchers have for the first time have used hydroacoustics as a method for comparing the abundance of fishes within and outside marine protected areas (MPAs). Find out more...

Thinking outside the box on climate mitigation

Fri, 12 Jan 2018 10:51:10 EST ~ A new article lays the groundwork for alternative climate mitigation scenarios that place less reliance on unproven negative emissions technologies in the future. Find out more...

California's water saving brings bonus effects

Thu, 11 Jan 2018 22:40:09 EST ~ Water-saving measures in California have also led to substantial reductions in greenhouse gas (GHG) emissions and electricity consumption in the state. Find out more...

All in the family: Focused genomic comparisons

Thu, 11 Jan 2018 22:39:54 EST ~ Aspergillus fungi are pathogens, decomposers, and important sources of biotechnologically-important enzymes. Scientists now report the first outcome from the large-scale sequencing of 300+ Aspergillus species. These findings are a proof of concept of novel methods to functionally annotate genomes to more quickly identify genes of interest. Find out more...

New hope for critically endangered Myanmar snub-nosed monkey

Thu, 11 Jan 2018 09:07:00 EST ~ Eight years after the discovery of a new primate species in Myanmar, scientists have released a new report revealing how the 'snubby' is faring. Find out more...
