Acoustic emissions evaluation of the dynamic splitting tensile properties of steel fiber reinforced concrete

Frontiers of Structural and Civil Engineering   Pages 1341-1356 doi: 10.1007/s11709-023-0988-4

Abstract: This study empirically investigated the influence of freeze–thaw cycling on the dynamic splitting tensileBrazilian disc splitting tests were conducted using four loading rates (0.002, 0.02, 0.2, and 2 mm/s)The dynamic splitting tensile damage characteristics were evaluated using acoustic emission (AE) parameterprocess; however, the primary crack type observed during the later stage of loading changed from shear to tensile

Generation of enhanced stability of SnO/In(OH)/InP for photocatalytic water splitting by SnO protection

Frontiers in Energy 2021, Volume 15, Issue 3,   Pages 710-720 doi: 10.1007/s11708-021-0764-x

Abstract: InP shows a very high efficiency for solar light to electricity conversion in solar cell and may present an expectation property in photocatalytic hydrogen evolution. However, it suffers serious corrosion in water dispersion. In this paper, it is demonstrated that the stability and activity of the InP-based catalyst are effectively enhanced by applying an anti-corrosion SnO layer and In(OH)3 transition layer, which reduces the crystal mismatch between SnO and InP and increases charge transfer. The obtained Pt/SnO/In(OH)3/InP exhibits a hydrogen production rate of 144.42 µmol/g in 3 h under visible light illumination in multi-cycle tests without remarkable decay, 123 times higher than that of naked In(OH)3/InP without any electron donor under visible irradiation.
