Effect of Peanut Shell Powder as a Pore‐Forming Additive in the Production of Ceramic Membranes

International Journal of Ceramic Engineering &Science, Volume 8, Issue 3, May 2026.
This study investigates the sustainable use of an agricultural by‐product, Peanut shell powder (PSP), to create pores in clay‐alumina membranes sintered at 1150°C. With 30 wt.% PSP, porosity reaches 49%, achieving high water flux (∼2300 L·h−1·m−2) and usable strength (17 MPa). Ideal for low‐cost membrane and effluent treatment.

Characterization of Ultrafast Decomposition Dynamics in Nitrate Esters

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 5, Page 714-723, May 2026.
ABSTRACT Ignition of energetic materials initiates chemical reactions on atomic length scales within femtoseconds, making these reactions difficult to investigate experimentally. The technique of femtosecond time‐resolved mass spectrometry (FTRMS) can capture molecular rearrangement and bond‐breaking events in isolated molecules with sub‐50 femtosecond
