Transitioning of the Chemical Industry Toward a Net‐Zero Carbon Dioxide Emission Path
Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.One way to reduce the greenhouse gas footprint of the chemical industry to almost zero would be the production of the platform molecules C1‐compounds, olefins, aromatics, and ammonia by non‐fossil pathways. The rest of the chemical production chains could be essentially left unchanged, provided the process energy input is renewable.

Materials and Corrosion, EarlyView.Ta‐Mo‐Cr‐Ti‐Al refractory high‐entropy alloys show atmosphere‐dependent oxidation performance based on Cr:Ti ratios. Cr‐rich compositions excel in dry oxygen through continuous chromia formation, while Ti‐rich alloys perform better in humid conditions due to reduced chromium volatilization and hydrogen uptake effects.

Effects of leakage vortex on aerodynamic performance and loss mechanism of steam turbine
Proceedings of the Institution of mechanical engineers. Part A, journal of power and energy, 2019 To avoid friction, a clearance between the rotor blade tip and the cylinder is needed in a steam turbine. As a result, the leakage flow is formed under the pressure difference which mixes with the main flow and causes the mixing loss.
