Nanotechnology approaches for creating biodeterioration-resistant wood

Posted by in categories: nanotechnology, sustainability

Emerging technologies such as nanotechnology can provide efficient approaches by which new materials with broad functions, such as durable and fire-retardant properties, can be developed and subsequently used for the treatment of wood materials.

In a study published in the Journal of Bioresources and Bioproducts, an international team from New Zealand (Scion) and China (Northeast Forestry University) report a review that nanotechnology-based methods can be employed to mitigate these weaknesses and create durable, sustainable wood materials.

These wood nanotechnologies also can be employed to develop wood products with antimicrobial surfaces for various applications. Furthermore, analytical tools used in nanoscience and nanotechnology enable the precise study of wood structure and its components on a nanometer scale, particularly those aspects that can affect wood products’ biodeterioration resistance properties.

Discovery of new material is ‘giant leap’ towards clean energy production and colonisation of Mars

Posted by in categories: energy, nanotechnology, space, sustainability

Scientists have developed a new material from a mineral abundant on Mars that they claim could open the door to sustainable habitation on the red planet.

Researchers assessed the potential of a type of nanomaterials – ultrasmall components thousands of times smaller than a human hair – for clean energy production and building materials on Mars.

The study, published in the journal Advanced Functional Materials, found that a material typically considered a waste product by NASA can be altered to provide clean energy and sustainable electronics.

MIT’s Breakthrough: Cooling Homes Without Electricity

Posted by in categories: climatology, habitats, sustainability

Let’s face it: on a scorching hot day, the sweet hum of an air conditioner feels like a lifeline. But what if that lifeline is actually tying us into a knot of environmental woes?

It turns out, our reliance on air conditioning is heating up the planet just as much as it’s cooling our homes.

Enter a team of ingenious researchers from MIT with a revolutionary idea: aerogel. This isn’t just another tech buzzword; it’s a potential game-changer in our fight against climate change.

Tesla acquires Shanghai land for megapack battery plant

Posted by in categories: government, sustainability, transportation

BEIJING/SHANGHAI, Dec 22 (Reuters) — Tesla (TSLA.O) has acquired land in Shanghai for a megapack battery manufacturing plant with production expected to start in the fourth quarter of 2024, Chinese state media reported on Friday.

Tesla paid 222.42 million yuan ($31.13 million) for use rights to a 19.7-hectare (48.7 acres) plot, a separate government statement said on Thursday. The site is near an existing Tesla plant producing Model 3 and Model Y cars.

Tesla did not immediately respond to a request for comment.

Fusion power may run out of fuel before it even gets started

Posted by in categories: particle physics, sustainability

For decades, achieving controlled fusion was a physics challenge. But now, as the ITER megaproject gears up to demonstrate fusion’s potential as an energy source—and startup companies race to beat it—the practical roadblocks to fusion power plants are coming into focus. One is a looming shortage of tritium fuel. Others could prevent reactors from ever running reliably—a necessity if fusion is to provide a constant “baseload” to complement intermittent solar and wind power.

Some of fusion’s fitfulness is innate to the design of doughnut-shaped tokamak reactors. The magnetic field that confines the ultrahot, energy-producing plasma is generated in part by the charged particles themselves, as they flow around the vessel. That plasma current in turn is induced by pulses of electrical current in a coil of wire in the doughnut’s hole, each lasting a few minutes at most. In between pulses the magnetic field ebbs, interrupting tokamak operations—and power delivery. The repetitive starts and stops of the reactor’s powerful magnetic fields also generate mechanical stresses that could eventually tear the machine apart.

In theory, the beams of particles and microwaves used to heat the plasma can also drive the plasma current. So can a quirk of plasma physics called the bootstrap effect. Near the edge of the plasma, a sharp pressure gradient causes the particles to spiral in such a way that they interfere with each other and push themselves—by their own bootstraps—around the ring.

Tesla launches Megapack project in Shanghai

Posted by in categories: energy, sustainability

Tesla has officially launched its new Megafactory project in Shanghai, which will produce 10,000 Megapacks per year, according to a statement today.

A signing ceremony for the land acquisition of the project was held in Shanghai on Friday morning, marking the start of what the company called a “milestone project”

The Megapack is a powerful battery that stores and supplies energy to help stabilize the grid and prevent power outages.

Quantum battery technology works by breaking causality

Posted by in categories: quantum physics, sustainability

Future batteries could charge up by relying on a quantum effect known as indefinite causal order, whereby the laws of cause and effect are scrambled and power can move through the system quicker.

Using ‘waste’ product from recent NASA research, scientists create transformative nanomaterials

Posted by in categories: chemistry, energy, nanotechnology, physics, space, sustainability

Researchers at the University of Sussex have discovered the transformative potential of Martian nanomaterials, potentially opening the door to sustainable habitation on the red planet.

Using resources and techniques currently applied on the International Space Station and by NASA, Dr. Conor Boland, a Lecturer in Materials Physics at the University of Sussex, led a research group that investigated the potential of nanomaterials—incredibly tiny components thousands of times smaller than a —for clean energy production and on Mars.

Taking what was considered a by NASA and applying only sustainable production methods, including water-based chemistry and low-energy processes, the researchers have successfully identified within gypsum nanomaterials—opening the door to potential clean energy and sustainable technology production on Mars.
