Since 2016, engineering firm NuScale has been working toward getting approval for a first-of-its-kind nuclear reactor, and late last week, the Nuclear Regulatory Commission (NRC) gave it the green light. The company’s pint-sized nuclear reactor has numerous safety benefits over larger reactors, and the small size makes it possible to build them at a centralized facility before shipping them to their final destination.

Nuclear power seems to flip between savior and boogeyman every few years. As climate change escalates due to the use of fossil fuels, nuclear is seen as a way to reduce carbon emissions while maintaining high electricity generation. However, all it takes is one accident like Fukushima or a reminder that Chernobyl is still incredibly dangerous decades later to make people second-guess the construction of new fission generators.

Musk responded to a question on Twitter as to whether he’d launch his own site by simply tweeting “X.com” on Tuesday. The comment came after it was revealed that the billionaire had sold 7.92 million Tesla shares worth $6.9 billion ahead of the very real chance he could be forced to purchase Twitter.

“In the (hopefully unlikely) event that Twitter forces this deal to close *and* some equity partners don’t come through, it is important to avoid an emergency sale of Tesla stock,” Musk said about the sale on Twitter.

JAKARTA, Aug 8 (Reuters) — U.S. carmaker Tesla (TSLA.O) has signed contracts worth about $5 billion to buy materials for their batteries from nickel processing companies in Indonesia, a senior cabinet minister told CNBC Indonesia.

Southeast Asia’s biggest economy has been trying to get Tesla to set up a production facility in the country, which has major nickel reserves. President Joko Widodo met with Tesla founder Elon Musk earlier this year to drum up investment. read more

“We are still in constant negotiation with Tesla … but they have started buying two excellent products from Indonesia,” Coordinating Minister for Maritime and Investment Affairs Luhut Pandjaitan said in an interview broadcast on Monday.

Tesla Inc TSLA CEO Elon Musk has taken Twitter by storm by sharing his “sex tape” tweet, sending his fans wild guesses.

What Happened: Musk shared an image that he labeled as his “sex tape,” showing two tape dispensers placed in a way that formed the number 69.

Then he joked in the caption, saying, “But have you seen my sex tape?”

Most of us have felt the shock from static electricity by touching a metallic object after putting on a sweater or walking across a carpet. This occurs as a result of charge build-up whenever two dissimilar materials (such as our body and the fabric) come in contact with each other.

In 2012, scientists from the U.S. and China used this phenomenon, known as “triboelectric effect,” to build a triboelectric nanogenerator (TENG) that converts unused mechanical energy into useful electrical energy. Their device consisted of two triboelectric polymer films with metallic electrodes, which, when brought together and separated, resulted in charge separation and the development of an electric voltage sufficient to power small electronic devices.

Viewed as potential sustainable energy harvesters, efforts have been made to enhance the power output of TENGs by injecting charges to the surface of triboelectric films. However, charge recombination in the electrode and charge repulsion on the surface of the material prevents them from achieving high surface charge densities.

The companies aim to achieve standardization in inductive charging systems.

Siemens and MAHLE have announced that the two companies signed a letter of intent.

They are teaming up to develop infrastructure and automotive engineering and to provide wireless charging to electric vehicles.

Solar cells based on organic molecules offer potential advantages over conventional devices for converting light into electricity. These organic solar cells could be inexpensive, durable, and easy to make. However, organic cells do not yet have the performance that matches conventional devices. Scientists’ efforts to improve performance have been limited by their limited understanding of how electrons excited by light (or “photoexcited”) become “free carriers.”

In principle, free carriers flow across a material and emerge as an electrical current. Prior scientific studies suggest that photoexcitation leads to a tightly bound pair consisting of an electron and a hole. These studies did not describe how to overcome the strong binding forces to form free carriers. This new study reveals that more sites on neighboring molecules can accept electrons, explaining how free carriers form directly.

Published in Materials Horizons, this research developed a new model called Distribution Range Electron Transfer (DRET). Previous models for the generation of free carriers in organic solar cells have generally invoked new physical phenomena to explain experimental results. In particular, they have said that free carriers can form with efficiency that approaches 100% in a material where opposite charges are traditionally difficult to separate and use.

The world is highly dependent on fossil fuels to power its industry and transportation. These fossil fuels lead to excessive carbon dioxide emission, which contributes to global warming and ocean acidification. One way to reduce this excessive carbon dioxide emission that is harmful to the environment is through the electroreduction of carbon dioxide into value-added fuels or chemicals using renewable energy. The idea of using this technology to produce methane has attracted wide interest. However, researchers have had limited success in developing efficient catalysts for methane.

A Soochow University research team has now developed a simple strategy for creating cobalt copper alloy catalysts that deliver outstanding methane activity and selectivity in electrocatalytic carbon dioxide reduction. Their research is published in Nano Research.

Over the past 10 years, scientists have made notable progress in advancing their understanding of catalysts and applying the knowledge to their fabrication. But the catalysts that have been developed have not been satisfactory for use with methane, in terms of selectivity or current density. Despite the great insights scientists have gained, the strategies they have attempted in creating catalysts for methane are just too costly to be useful in practical applications.
