The flow of China's carbon emissions has reversed according to new research led by scientists at the University of East Anglia (UEA). The study estimates the carbon implications of recent changes in the country's economic development patterns and role in international trade since the global financial crisis.
An empirical model of 55 of California's major reservoirs reveals how they respond to shifting drought conditions and to one another.
New research on oxygen and iron chemistry under the extreme conditions found deep inside the Earth could explain a longstanding seismic mystery called ultralow velocity zones. Published in Nature, the findings could have far-reaching implications on our understanding of Earth's geologic history, including life-altering events such as the Great Oxygenation Event, which occurred 2.4 billion years ago.
The discovery of nanoscale changes deep inside hybrid perovskites could shed light on developing low-cost, high-efficiency solar cells. Using X-ray beams and lasers, a team of researchers led by the University of California San Diego discovered how the movement of ions in hybrid perovskites causes certain regions within the material to become better solar cells than other parts.
Three new research studies from the University of Texas at Arlington have found harmful pathogenic bacteria in Texas groundwater near unconventional natural gas extraction sites.
Scientists from the Princeton Plasma Physics Laboratory have built and delivered a high-resolution X-ray spectrometer for the largest and most powerful laser facility in the world.
In a breakthrough development, Los Alamos scientists have shown that they can successfully amplify light using electrically excited films of the chemically synthesized semiconductor nanocrystals known as quantum dots.
Electronic devices such as computers generate heat that mostly goes to waste. Physicists at Bielefeld University have found a way to use this energy: They apply the heat to generate magnetic signals known as 'spin currents'. In future, these signals could replace some of the electrical current in electronic components.
Scientists from ITMO University have developed a new solar cell coating based on amorphous silicon that combines the features of an electrode and those of a light-trapping structure. The coating enabled researchers to cut down on reflected light and avoid the overheating of solar cells, thus increasing their overall efficiency by 20%. Moreover, the suggested method is highly suitable for industrial needs due to its relatively low cost and simplicity. The research was published in Optics Letters.
Novel approach utilizes high mobility two-dimensional electron gas, boosting thermoelectric conversion efficiency.
