Performance–Emission Trade‐Offs in RCCI Engines Using High‐Viscosity Alcohol–Diesel Blends Under Variable Injection Pressures

open access: yesEngineering Reports, Volume 8, Issue 1, January 2026.
Blending high‐viscosity 2‐Methyl‐1‐butanol with diesel in an RCCI engine enhanced thermal efficiency and significantly reduced NOx and smoke emissions. The D70MB30 blend at 800 bar injection pressure achieved the best performance–emission trade‐off, supporting cleaner and more sustainable combustion.

Mechanical and Physical Performance of Mortars Incorporating Crushed Hazelnut Shells as Partial Fine Aggregate Replacement

open access: yesAdvances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
This study investigates the mechanical and physical properties of mortars incorporating crushed hazelnut shell (HS) as a partial replacement for fine aggregates. Mortar mixtures were prepared with varying water‐to‐cement (w/c) ratios ranging from 0.35 to 0.50 and HS dosages of 2.5%, 5%, and 7.5% by weight, along with reference mixtures without HS.
