Polypropylene-based aerogels with high surface area have been developed for the first time. By chemical crosslinking of polypropylene with oligomeric capped-end amino compounds, followed by dissolution, thermally induced phase separation, and the supercritical CO₂ drying process or freeze-drying...

Ammonia is expected to play an important role in the green transition, both as a hydrogen carrier and a zero-emission fuel. The use of refrigerated ammonia is attractive due to its relatively high volumetric energy density and increased safety compared to pressurized solutions. Ammonia is highly...

A rapid freezing of a sea water droplet moving in a cold air is modeled. A droplet freezing model is a key component needed for computational forecasting of ice accretion on surfaces of ships and other equipment operating in low-temperature regions. The freezing process consists of the three stages...

Dissimilar aluminium alloy-tailor weld blanks (DA-TWB) are increasingly being used in transportation industries due to their significant benefit in reinforcing vehicle structures as well as improving lightweight performance. Hot stamping technologies enabling the manufacture of lightweight pressings...
