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.

Thus, engineered wood has emerged as a sustainable and environmentally friendly alternative to traditional building materials. However, this wood is prone to warping and deterioration of structural integrity, diminishing its life span.

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.

A Biodegradable Computer Chip That Performs Surprisingly Well

Posted by in categories: computing, sustainability

Year 2015 face_with_colon_three

Biodegradable, wood-based computer chips can perform just as well as chips commonly used for wireless communication, according to new research.

The inventors argue that the new chips could help address the global problem of rapidly accumulating electronic waste, some of which contains potentially toxic materials. The results also show that a transparent, wood-derived material called nanocellulose paper is an attractive alternative to plastic as a surface for flexible electronics.

This startup uses grass to build energy-efficient building panels

Posted by in categories: energy, sustainability

This innovative startup is revolutionizing architecture — with building panels made out of fastest-growing perennial grass on Earth.

With housing shortages in need of quick fixes, the manufacturing industry is facing a conundrum: how to source materials and build structures while cutting down on emissions. The answer lies with sustainable construction — not only could it help reduce our environmental impact, but it also keeps costs low during implementation.

Recently, a new startup named Plantd achieved a milestone of building ultra-strong building panels out of the fastest-growing perennial grass on Earth — the best sustainable alternative to construction.

‘Flash Joule’ technique efficiently turns would-be pollution into valuable nanomaterials

Posted by in categories: economics, nanotechnology, sustainability

Putting that soda bottle or takeout container into the recycling bin is far from a guarantee it will be turned into something new. Scientists at Rice University are trying to address this problem by making the process profitable.

The amount of waste produced globally has doubled over the past two decades—and plastic production is expected to triple by 2050—with most of it ending up in landfills, incinerated or otherwise mismanaged, according to the Organization for Economic Cooperation and Development. Some estimates suggest only 5% is actually being recycled.

“Waste plastic is rarely recycled because it costs a lot of money to do all the washing, sorting and melting down of the plastics to turn it into a material that can be used by a factory,” said Kevin Wyss, a Rice graduate student and lead author on a study published in Advanced Materials that describes how he and colleagues in the lab of chemist James Tour used their flash Joule heating technique to turn plastic into valuable carbon nanotubes and hybrid nanomaterials.

Ammonium-ion batteries — a metal-free solution for sustainable power?

Posted by in category: sustainability

The batteries comprise ammonium-ion electrolytes that may provide an environmentally friendly competitor to traditional metal-ion batteries dependent on precious, finite, and consistently dwindling resources. The ammonium-ion batteries may also have uses in several fields, most notably for grid storage.

KAUST researchers have innovated metal-free, ammonium-ion batteries that provide a sustainable alternative to power the green transition.
