Slurry

Video cameras mounted on an autonomous underwater robot captured footage of cracks associated with mud volcanism close to a potentially active fault on the shores of Lake Baikal.

The tiny fragments that tires shed are yet another reason to reduce car use.

Insiders say Quick Start is a major reason why the state has successfully wooed billions in investment from the world's leading solar, battery and EV companies.

With the new slurry, Liu Ren was able to print ceramic torsion springs at 3.5 millimeters thickness which retained their shape in mid-air.

Scientists in China have developed a new 3D printing technique that allows ceramics to be printed in mid-air without support structures.

DENVER (AP) — From Colorado's high desert to the wooded hills of Pennsylvania, millions...

One of the challenges of realizing smart dust concepts, as well as nano- and microrobotics in general, is a lack of equally small on-chip power sources for ubiquitous anytime anywhere operation. Now, researchers have created an on-chip micro-Swiss-roll battery by using a self-assembly process known as micro-origami. The batteries are 3 mm in length and about 178 micros in diameter and the self-assembly mechanism…

A new model suggests "mantle rain" ensures we will always have a surface ocean

Startups like Solid Power are beginning to roll out solid-state batteries that meet the needs of EVs. But hurdles remain for manufacturing them at scale.

Biochar has been used in agriculture for millennia, but industrial applications and a growing climate crisis mean it's in new demand.

Low-cost alternative to concrete absorbs CO2 during its formation

More than 200 earthquakes of 3 magnitude and greater shook Texans in 2021, more than...

By Gregory T. Benz, Lee Enterprise Consulting Partners/Benz Technology International Inc. Special to The Digest There are many ways to produce hydrogen: electrolysis, catalytic methods on alkane gasses, pyrolysis or organic matter and "wet" processing of biomass, usually converting to sugars before conversion to hydrogen. This brief paper is not about the reaction chemistry, but […]

A process to dissolve the mineral olivine in acid could provide a plentiful, energy-efficient material for carbon-negative cement

As high-yield oil supplies become harder to find, energy companies are turning to oil sands: mixtures of bitumen, sand and water. How do you extract oil from mucky, viscous soil?

The tiny fragments that tires release into the environment are yet another reason to reduce car use

In a collaboration led by Aarhus University, researchers have measured nitrous oxide emissions during two years at four different locations in Denmark, where representative crop rotations had been established to provide a realistic context for the measurements.

In an era of expertly manicured fields and shared knowledge among groundskeepers, crews have an unexpected tool in their arsenal: the ban on infield shifts.

Hundreds of landfills containing toxic coal ash have gone unregulated for years, posing hazards to human health and the environment.
