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.

Non-glaring photovoltaic installations

Before a photovoltaic installation may be constructed, engineers calculate, for some selected days in the year, when and where the interfering light reflections occur, especially if airports, highways or larger residential areas are close by. In the future, this will be easier and more comprehensive: with software that creates a three-dimensional depiction of the glare at the touch of a button.

Improving climate protection in agriculture

Agriculture is responsible for around ten to twelve percent of all greenhouse gases attributable to human activities. This raises the question of how these emissions could be reduced. A recent study has investigated - for the first time - the full range of factors that contribute to greenhouse gas emissions, namely soil and climate conditions, the agricultural model and the farming intensity on both organic and conventional holdings.
