Superior Abrasibility of YSZ(ESP)/BN@ZrO2‐Polyester Composite Sealing Coating Reinforcing With Hybrid Micron/Nanometer Multiscaled Pore Structure

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Composite materials hold significant potential for abrasive sealing, yet composite materials used for abrasive sealing fall short in service durability under extreme environments. Here, a controllable strategy for adjusting pore structure is proposed, aiming to design a YSZ(ESP)/BN@ZrO2‐polyester coating with hybrid micron/nanometer ...

Efficient Hydrogenation of Furfural to Furfuryl Alcohol Using Cu‐Impregnated Chromium Silicate Catalysts in Ethanol Media

ChemistrySelect, Volume 11, Issue 17, 5 May 2026.
Efficient hydrogenation of furfural to furfuryl alcohol over a Cu‐impregnated mesoporous Cr‐silicate catalyst synthesized with PDADMAC, achieving complete conversion and 86% selectivity under mild ethanolic conditions. ABSTRACT A 10 wt.% Cu‐impregnated chromium silicate catalyst was synthesized via a sol–gel method followed by hydrothermal treatment ...

Assessing Deposit‐Derived Pyroclastic Flow Hazard at Stromboli (Italy): 1. Reconstruction of the Dynamics of the 11 September 1930 Event

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Stromboli volcano (Italy) is known for its persistent explosive activity punctuated by more energetic explosions called paroxysms. During paroxysms, pyroclastic density currents, triggered by the gravitational instability of hot pyroclastic deposits, can occur.
