NIST designs a prototype fuel gauge for orbit
Liquids aren't as well behaved in space as they are on Earth. Inside a spacecraft, microgravity allows liquids to freely slosh and float about. This behavior has made fuel quantity in satellites difficult to pin down, but a new 3D-imaging fuel gauge engineered at the National Institute of Standards and Technology could offer an ideal solution.

Climate change causes landfalling hurricanes to stay stronger for longer
Climate change is causing hurricanes that make landfall to take more time to weaken, reports a study published 11th November 2020 in leading journal, Nature. The researchers showed that hurricanes that develop over warmer oceans carry more moisture and therefore stay stronger for longer after hitting land. This means that in the future, as the world continues to warm, hurricanes are more likely to reach communities farther inland and be more destructive. (2020-11-11)

Decrease in fossil-fuel CO2 emissions due to COVID-19 detected by atmospheric observations
Atmospheric observations at Hateruma Island, Japan, successfully detected the decrease in fossil-fuel CO2 emissions in China associated with the COVID-19 outbreak. The weather in Hateruma island is frequently influenced by the northwest monsoon travelling over China, which carries the emission signals of air pollutants. The observed ratios of CO2 and CH4 variabilities showed a significant decrease during February-March 2020, corresponding to about a 30% decrease in China's fossil-fuel CO2 emissions, according to a chemistry-transport model simulation.

How to fix the movement for fossil fuel divestment
Bankers and environmentalists alike are increasingly calling for capital markets to play a bigger role in the war on carbon. In the absence of a meaningful global price on carbon, however, capital continues to flow freely toward fossil fuels and other carbon-intensive industries. The movement for fossil fuel divestment has been trying since 2012 to reverse this trend. (2020-11-03)

Leaving more big fish in the sea reduces CO2 emissions
Leaving more big fish--like tuna, sharks, mackerel and swordfish--in the sea reduces the amount of carbon dioxide (CO2) released into the Earth's atmosphere.This is because when a fish dies in the ocean it sinks to the depths and sequestrates all the carbon it contains with it. This is a form of 'blue carbon'. Big fish are about 10 to 15 percent carbon. (2020-10-28)

National laboratories point to sugars as a key factor in ideal feedstock for biofuels
Popular wisdom holds that tall, fast-growing trees are best for biomass, but new research by two US Department of Energy National Laboratories reveals the size of trees is only part of the equation. Of equal economic importance, according to scientists from the US Department of Energy's National Renewable Energy Laboratory (NREL) and Oak Ridge National Laboratory (ORNL), is the amount of sugars that can be produced from the ligno-cellulosic biomass that can be converted into fuels.

High-performance single-atom catalysts for high-temperature fuel cells
Platinum (Pt)-based catalysts demonstrate such excellent performance in fuel cell electrode reactions. However, at high temperatures, the Pt atoms are not stable and easily agglomerate. Therefore, Pt single-atom catalysts have been used only in low-temperature fuel cells, like polymer-electrolyte membrane fuel cells, which is used for hydrogen electric vehicles. Under these circumstances, a domestic research team have developed a catalyst that requires only a small amount of platinum for the significant improvement of performance and can operate stably at high temperatures.

Comprehensive look at US fuel economy standards show big savings on fuel and emissions
In one of the first comprehensive assessments of the fuel economy standards in the US, researchers found that, over their 40-year history, the standards helped reduce reliance on foreign oil producers, saved $5 trillion in fuel costs and prevented 14 billion metric tons of carbon from being released into the atmosphere. The standards (known as CAFE standards), first enacted to reduce foreign oil dependence, were cost-effective, fair, durable and adaptive, the researchers found. (2020-09-03)

Nano-sponges of solid acid transform carbon dioxide to fuel and plastic waste to chemicals
The primary cause of climate change is atmospheric CO2, whose levels are rising every day. There is, therefore, a great need to find ways to reduce CO2 levels. On other hand, an excessive amount of plastic waste has become a serious environmental problem. In this work, researchers dealt with both these problems at one stroke, by developing nano solid acids which transform CO2 directly to fuel (dimethyl ether) and plastic waste to chemicals (hydrocarbons).
