Researchers uncover new water monitoring technique

Posted by in categories: biological, chemistry, engineering, particle physics, sustainability

Water is a vital resource, and clean water is a necessity. Texas A&M University researchers have developed a new technique to monitor one of the key processes of purifying water in real time.

Raw water contains microscopic pathogens that are too small to remove during water and easily. Chemicals are added to form large clumps called flocs, which are easily filtered out. Flocculation is the process used in water treatment to remove suspended particles from the water.

“Coagulant chemicals need to be added to purify drinking water and remove turbidity (cloudiness) and microbes that are too small to be visible to the ,” said Dr. Kuang-An Chang, professor in the Zachry Department of Civil and Environmental Engineering at Texas A&M.

A hydrogen-powered autonomous ship could help decarbonize maritime transport

Posted by in categories: government, robotics/AI, sustainability, transportation

The ship could be ready by the autumn of 2024.

A consortium of companies in the U.K. has bagged a GBP 5.4 million (US$6.46) government grant to build the world’s first liquid hydrogen-powered autonomous vessel and its allied infrastructure, a press release said. The grant is aimed at helping decarbonize the maritime sector.

Corralling ions improves viability of next generation solar cells

Posted by in categories: solar power, sustainability

Researchers have discovered that channeling ions into defined pathways in perovskite materials improves the stability and operational performance of perovskite solar cells. The finding paves the way for a new generation of lighter, more flexible, and more efficient solar cell technologies suitable for practical use.

Perovskite materials, which are defined by their , are better at absorbing light than silicon is. That means that can be thinner and lighter than silicon solar cells without sacrificing the cell’s ability to convert light into electricity.

“That opens the door to a host of new technologies, such as flexible, lightweight solar cells, or layered solar cells (known as tandems) that can be far more efficient than the solar harvesting technology used today in so-called solar farms,” says Aram Amassian, corresponding author of a paper on the discovery. “There’s interest in integrating materials into silicon solar cell technologies, which would improve their efficiency from 25% to 40% while also making use of existing infrastructure.” Amassian is a professor of materials science and engineering at North Carolina State University.

Nokia launches smartphone you can fix yourself, jumping on ‘right to repair’ trend

Posted by in categories: mobile phones, sustainability

Armed with tools and repair guides from hardware repair advocacy firm iFixit, a user can remove and replace the phone’s back cover, battery, screen and charging port.

Adam Ferguson, head of product marketing at HMD Global, said that this process would cost on average 30% less than replacing an old phone with a new one.

Smartphone companies are increasingly working to make phones last for longer amid pressure from regulators to make electronics devices more sustainable.

An entry-level Tesla now costs less than the average new car

Posted by in categories: sustainability, transportation

After the automaker started slashing prices on its vehicles earlier this year, making them more affordable than some new gas-powered cars.

The Tesla Model 3 now starts at $43,000, not including the $7,500 tax credit Americans can get for buying an electric vehicle. That brings the after-rebate price of a Model 3 down to $35,500.

-plus other companies are lowering prices because of Tesla.

NASA Issues Award for Greener, More Fuel-Efficient Airliner of Future

Posted by in categories: space, sustainability

NASA announced Wednesday it has issued an award to The Boeing Company for the agency’s Sustainable Flight Demonstrator project, which seeks to inform a potential new generation of green single-aisle airliners.

Under a Funded Space Act Agreement, Boeing will work with NASA to build, test, and fly a full-scale demonstrator aircraft and validate technologies aimed at lowering emissions.

Over seven years, NASA will invest $425 million, while the company and its partners will contribute the remainder of the agreement funding, estimated at about $725 million. As part of the agreement, the agency also will contribute technical expertise and facilities.

Anti-dust tech paves way for self-cleaning surfaces

Posted by in categories: solar power, space travel, sustainability

Dust is a common fact of life, and it’s more than just a daily nuisance—it can get into machinery and equipment, causing loss of efficiency or breakdowns.

Researchers at The University of Texas at Austin partnered with North Carolina-based company Smart Material Solutions Inc. to develop a new method to keep dust from sticking to surfaces. The result is the ability to make many types of materials dust resistant, from spacecraft to solar panels to household windows.

The research is published in ACS Applied Materials & Interfaces.

Researchers use light to convert abundant lignin into plastic that can be continually recycled

Posted by in categories: chemistry, sustainability

Lignin is arguably the most abundant component of biomass that most people have never heard of. That may be about to change.

Many people are familiar with its biochemical cousin cellulose, a byproduct of paper and wood milling. But the same processes produce 50 million tons of lignin annually, industry experts estimate. Once distilled, 98 percent of the inky liquid is burned to produce electricity.

Scientists have been working to find more efficient and sustainable approaches to transform this naturally occurring polymer for use as a cleaner and greener building block to develop next generation materials.

Tesla Cybertruck sightings continue, this time with better look at air suspension

Posted by in categories: sustainability, transportation

Tesla Cybertruck sightings are continuing, and a video of the all-electric pickup released today gives a much better look at the vehicle’s air suspension.

Last night, a video of the Cybertruck rolling around Gigafactory Texas was shared, showing off its air suspension at what people said was its maximum ride height. However, it was very unclear and grainy, so it didn’t necessarily give a great look at what the Cybertruck will look like when utilizing its air suspension.

Now, a new video has been shared, where the Cybertruck appears to be, once again, at its maximum ride height, thanks to its air suspension, but the clearer resolution gives us a much more revealing look at the beast in its rarest form.
