GM unveiled Monday evening the Chevrolet Blazer EV, an all-electric SUV with up to 320 miles of range and a starting price of $48,000 that CEO and Chairman Mary Barra hopes will supercharge her bid to surpass Tesla in U.S. EV sales by 2025.

The Chevrolet Blazer EV, which will go on sale in 2023 as a 2024 model year, isn’t the only impending GM electric vehicle. A slew of Cadillac and Chevy EVs are also making their way to market. But the Blazer, at its more affordable price point and in the lucrative SUV segment, could kick-start GM’s sales goals.

Internally, the confidence is high. Blazer is going be a massive statement and illustrate how GM can hit big volume segments, according to Scott Bell, Global VP of Chevrolet.

The computational design of functional materials relies heavily on large-scale atomistic simulations. Such simulations are often problematic for conventional classical force fields, which require tedious and time-consuming parameterization of interaction parameters. The problem can be solved using a quantum mechanically derived force field (QMDFF)—a system-specific force field derived directly from the first-principles calculations. We present a computational approach for atomistic simulations of complex molecular systems, which include the treatment of chemical reactions with the empirical valence bond approach. The accuracy of the QMDFF is verified by comparison with the experimental properties of liquid solvents.

A space elevator, a technology connecting the Earth’s surface to a space station, would allow for the cost-efficient transport of people and materials. However, a very light yet strong material is essential to making such a technology a reality.

The carbon nanotube is a material that is 100 times stronger, yet four times lighter, than steel, with copper-like high electrical conductivity and diamond-like thermal conductivity. However, previous carbon nanotube fibers were not ideal for extensive use, owing to the small contact area with adjacent carbon nanotubes and limited length they possessed.
