Electronic entropy enhances water splitting

An electron transitioning from state to state increases cerium's entropy, making it ideal for hydrogen production, researchers have found.

Single nanoparticle mapping paves the way for better nanotechnology

Researchers have developed a method that makes it possible to map the individual responses of nanoparticles in different situations and contexts. The results pave the way for better nanomaterials and safer nanotechnology.

Expanding Brazilian sugarcane could dent global CO2 emissions

Vastly expanding sugarcane production in Brazil for conversion to ethanol could reduce current global carbon dioxide emissions by as much as 5.6 percent, researchers report. This can be accomplished without impinging on environmentally sensitive areas in Brazil and while allowing for the expansion of other agricultural crops and human needs, the researchers report.

Purple power: Synthetic 'purple membranes' transform sunlight to hydrogen fuel

A new way has been found to produce solar fuels by developing “synthetic purple membranes.” These membranes involve an assembly of lipid nanodiscs, man-made proteins, and semiconducting nanoparticles that, when taken together, can transform sunlight into hydrogen fuel.

Converting carbon dioxide to carbon monoxide using water, electricity

Researchers have determined how electrocatalysts can convert carbon dioxide to carbon monoxide using water and electricity. The discovery can lead to the development of efficient electrocatalysts for large scale production of synthesis gas -- a mixture of carbon monoxide and hydrogen.

Mimicking two natural energy processes with a single catalyst

Researchers take inspiration from natural chemical processes based on hydrogenase and photosystem II, to produce a single metal catalyst with both fuel cell and solar cell functionalities. The combination of these two processes into one system suggests great potential for biologically inspired energy generation technologies.

New nanomaterial can extract hydrogen fuel from seawater

A new hybrid nanomaterial harvests solar energy and uses it to extract hydrogen from seawater, cheaply and efficiently. Future commercialization could mean a new source of environmentally friendly fuel and less dependence on fossil fuels.

A new way to produce clean hydrogen fuel from water using sunlight

Researchers combined graphitic carbon nitride and black phosphorous to make a new metal-free composite photocatalyst capable of producing hydrogen from water. The photocatalyst featured good photocatalytic production of hydrogen, even when powered by low-energy near infrared light.

Surrounded by potential: New science in converting biomass

To take full advantage of biomass, lignin needs to be processed into usable components along with the plant cellulose. Currently, that process requires an acid plus high heat, or pyrolysis -- treating with high heat in the absence of oxygen. Besides being energy-consuming processing methods, the results are less than optimal. Scientists are now working to develop a method to deconstruct lignin in a way that is economically feasible and into stable, readily useful components.

New efficient catalyst for key step in artificial photosynthesis

Chemists have designed a new 'single-site' catalyst that speeds up the rate of a key step in artificial photosynthesis. It's the first to match the efficiency of the catalytic sites that drive this reaction in nature and could greatly improve the potential for making efficient solar-to-fuel conversion devices.

Compound from oilseeds may be high-value product

Extracting a substance called glucosinolate from camelina and carinata seeds may help bring these promising sources of biofuel one stop closer to reality.

Ultra-fast and ultra-sensitive hydrogen sensor

Scientists have made an ultra-fast hydrogen sensor that can detect hydrogen gas levels under 1 percent in less than seven seconds. The sensor also can detect hundreds of parts per million levels of hydrogen gas within 60 seconds at room temperature.

Sensible driving saves more gas than drivers think

A new study has quantified the impact speeding and slamming on the brakes has on fuel economy and consumption. Aggressive behavior behind the wheel can lower gas mileage in light-duty vehicles, which can equate to losing about $0.25 to $1 per gallon.

Hydrogen power moves a step closer

Physicists are developing methods of creating renewable fuel from water using quantum technology. Renewable hydrogen can already be produced by photoelectrolysis where solar power is used to split water molecules into oxygen and hydrogen. But fundamental problems remain before this can be adopted commercially due to inefficiency. A new study demonstrates that the novel use of nanostructures could increase the maximum photovoltage generated in a photoelectrochemical cell, increasing the productivity of splitting water molecules.

Graphene-wrapped nanocrystals makes inroads toward next-gen fuel cells

A new study provides insight into how an ultrathin coating can enhance the performance of graphene-wrapped nanocrystals for hydrogen storage applications.

Ten million tonnes of fish get wasted every year: study

Industrial fishing fleets dump nearly 10 million tonnes of good fish back into the ocean every year - enough to fill about 4,500 Olympic sized swimming pools - a study has found.
