Effects of natural gas assessed in study of shale gas boom in Appalachian basin

Втр, 2019-12-17 21:15
A new study estimated the cumulative effects of the shale gas boom in the Appalachian basin in the early 2000s on air quality, climate change, and employment. The study found that effects on air quality and employment followed the boom-and-bust cycle, but effects on climate change will likely persist for generations to come. The study, which also considered how to compensate for these effects, provides insights for long-term decision making in this field.

Fine-tuning thermoelectric materials for cheaper renewable energy

Artificial intelligence may help scientists make spray-on solar cells

Пн, 2019-12-16 19:24
Artificial Intelligence may be just the thing to accelerate spray-on solar cell technology, which could revolutionize how consumers use energy. A research team has used Machine Learning, aka Artificial Intelligence to optimize the materials used to make perovskite solar cells (PSC). The Organic-Inorganic halide perovskites material used in PSC converts photovoltaic power into consumable energy.

Researchers perfect nanoscience tool for studies of nuclear waste storage

Чтв, 2019-12-12 21:19
Studying radiation chemistry and electronic structure of materials at scales smaller than nanometers, scientists prepared samples of clay in ultra-thin layers. Working at the TRIUMF particle accelerator, they bombarded the samples with antimatter subatomic particles. They found their system is a proven tool for radiation studies of material to be used to store nuclear waste -- important for Canadian nuclear industry looking to build its first geological repository.

Ethylene, or ethene, is a primary feedstock for the chemical industry, including as a starting material for the production of a wide variety of plastics. Scientists have now introduced a new electrochemical technique for selective and energy-efficient production of ethylene from carbon monoxide, which can be obtained from renewable resources and waste.

Punching holes in opaque solar cells turns them transparent

Срд, 2019-12-11 18:55
Researchers in Korea have found an effective and inexpensive strategy to transform solar cells from opaque to transparent. Existing transparent solar cells tend to have a reddish hue and lower efficiency, but by punching tiny holes on crystalline silicon wafers, it allows light through without coloring. The holes are then strategically spaced, so the human eye is unable to 'see' the pattern.

Green hydrogen: Research to enhance efficiency

Пн, 2019-12-09 17:20
Laboratory experiments and a parabolic flight campaign have enabled an international team of researchers to gain new insights into water electrolysis, in which hydrogen is obtained from water by applying electric energy. Water electrolysis could play a key role in the energy transition if efficiency improvements can be achieved. The findings offer a possible starting point for enhancing the environmental impact of hydrogen-based technologies.

As China rapidly adopts clean energy, use of traditional stoves persists

Чтв, 2019-12-05 22:53
Old habits are hard to break. A new study of replacement of traditional wood and coal burning stoves with clean energy in China suggests that, without a better understanding of the reasons behind people's reluctance to give up traditional stoves, it will be difficult for policies in China and elsewhere in the world to succeed in encouraging this shift towards clean energy.

Microwave treatment is an inexpensive way to clean heavy metals from treated sewage

Чтв, 2019-12-05 20:05
A team of researchers studying new methods to remove toxic heavy metals from biosolids -- the solid waste left over after sewage treatment -- found the key is a brief spin through a microwave.

Fusion by strong lasers

Чтв, 2019-12-05 18:32
Nuclear physics usually involves high energies, as illustrated by experiments to master controlled nuclear fusion. One problem is how to overcome the strong electrical repulsion between atomic nuclei which requires high energies to make them fuse. But fusion could be initiated at lower energies with electromagnetic fields that are generated by state-of-the-art free electron lasers emitting X-ray light. Researchers describe how this could be done.

Thermo-chemical power generation integrated with forced convection cooling

Срд, 2019-11-27 23:12
Scientists combine forced convection cooling with thermo-electrochemical energy conversion to create a self-sustaining liquid cooling system. A liquid electrolyte is circulated through a cell to cool a hot object, and the reversible chemical reaction in the cell generates a higher electric power than the hydrodynamic pump work required to drive the liquid through the cell. This technology resolves the longstanding unaddressed issue of the loss of free energy component of the thermal energy.
