Iron-based solar cells on track to becoming more efficient

An international study led from Lund University in Sweden shows that 30 percent of the energy in a certain type of light-absorbing iron molecule disappears in a previously unknown manner. By closing this loophole, the researchers ...

Huge fire breaks out at Philadelphia oil refinery

A huge blaze erupted at a Philadelphia oil refinery early Friday, injuring five people, forcing residents to shelter in place for hours and causing gasoline prices to rise, officials said.

Eliminating infamous security threats

Speculative memory side-channel attacks are security vulnerabilities in computers for which no efficient solutions have been found. Existing solutions only address specific security threats without solving the underlying ...

Coffee-based colloids for direct solar absorption

Solar energy is one of the most promising resources to help reduce fossil fuel consumption and mitigate greenhouse gas emissions to power a sustainable future. Devices presently in use to convert solar energy into thermal ...

Sustainable pellet production saving lives

The world needs more efficient energy systems based on renewable raw material, an equation not easily solved. At Karlstad University, research and education are in progress to find sustainable energy systems, for instance, ...

A new way to transfer energy between cells

Researchers from the Catalonian Institute of Bioengineering (Instituto de Bioingeniería de Cataluña) and the Seville Chemical Research Institute (Instituto de Investigaciones Químicas de Sevilla) have described a new method ...

New facades enhance energy efficiency of buildings

Recently, two researchers from UPM have developed a ventilated façade with a double chamber and flow control device that significantly saves energy in buildings. This sustainable, efficient solution can be applied in both ...

Quantum tunnelling in water opens the way to improved biosensing

Researchers at the University of Sydney have applied quantum techniques to understanding the electrolysis of water, which is the application of an electric current to H2O to produce the constituent elements hydrogen and oxygen.

Opinion: A 'cleanish' energy target gets us nowhere

It seems that the one certainty about any clean energy target set by the present government is that it will not drive sufficient progress towards a clean, affordable, reliable energy future. At best, it will provide a safety ...
