Hydrogen futures: toward a sustainable energy system

Fueled by concerns about urban air pollution, energy security, and climate change, the notion of a “hydrogen economy” is moving beyond the realm of scientists and engineers and into the lexicon of political and business leaders. Interest in hydrogen, the simplest and most abundant element in the universe, is also rising due to technical advances in fuel cells — the potential successors to batte...

TOWARD A SUSTAINABLE FOOD SYSTEM Reducing Food Loss and Waste

Sustainable carbon materials.

Carbon-based structures are the most versatile materials used in the modern field of renewable energy (i.e., in both generation and storage) and environmental science (e.g., purification/remediation). However, there is a need and indeed a desire to develop increasingly more sustainable variants of classical carbon materials (e.g., activated carbons, carbon nanotubes, carbon aerogels, etc.), par...

Materials for sustainable energy.

Materials for solar fuels and chemicals Joseph H. Montoya, Linsey C. Seitz, Pongkarn Chakthranont, Aleksandra Vojvodic, Thomas F. Jaramillo and Jens K. Nørskov 70 Available and affordable energy has so far led to spectacular industrialization and development, but with growth accelerating in developing countries, demands on non-renewable energy sources are reaching their limits. Moreover, the re...

A Step toward a Sustainable Diet by Reducing Carbon Footprint: A Case Study in Iran

Introduction: Greenhouse gas (GHG) emissions have caused environmental effects. Food production is one of the sources of GHGs. This study aimed to suggest dietary scenarios for decreasing GHG emissions. Materials and Methods: GHG emissions in the target population of Urmia city, Northwest Iran, were investigated using a modeling approach. Three dietary scenarios were modeled and analyzed to ev...
