Insulating buildings with seaweed

Although this natural material is regarded as a waste product and generally ends up as landfill, this readily abundant and renewable material is in fact far too valuable to be thrown away. The seaweed displays a variety of characteristics that make it of interest to the building trade, such as virtual non-flammability and resistance to mould.

Doped carbon material produces low-cost energy and reduces CO2

Researchers from the University of Granada (UGR) have developed a new material using doped carbon that allows low-cost energy to be produced and also reduces the amount of CO2 released into the atmosphere. The recently-patented material is a gel that enables the CO2 to be turned back into hydrocarbons via electro-catalytic transformation, with great savings both in time and money.

Statistical physics offers a new way to look at climate

New research suggests that statistical simulations rooted in basic physics could make for new climate models that are more useful and require less brute-force computing power. A new paper shows how statistical simulations can be applied to fluid jets like the ones in Earth's atmosphere and oceans.

New method for greenhouse gas predictions

Until now, greenhouse gas emission estimates have been limited by the mathematical models used to predict them. Researchers at Concordia University have recently developed a new dynamic method to better predict the emission content of these gases.

Analytical theory may bring improvements to lithium-ion batteries

Researchers have shown theoretically how to control or eliminate the formation of "dendrites" that cause lithium-ion batteries to fail, an advance that if realized would improve safety and might enable the batteries to be charged within a matter of minutes instead of hours.
