De-aluminated metakaolin-cement composite modified with commercial titania as a new green building material for gamma-ray shielding applications

“…3) show presence of sharp peaks from the anatase phase (TiO 2 , 2θ = 25.9, 37.9, 48, 53.8, 55.1, 62.5 and 68.4 • with (101), ( 112), ( 200), ( 105), ( 211), ( 204) and ( 216) diffraction planes, respectively, PDF# 01-071-1167). The average crystallite size for the anatase phase estimated from XRD-pattern is 21 nm, using Debye -Scherrer's equation (D= 0.9λ/βcosθ) [56,57]; Where, 0.9: shape factor, λ: X-ray wavelength, β: line broadening at half of the maximum intensity in radian (FWHM), and θ: Bragg angle (in degree). The anatase phase a tetragonal structures have a [TiO6] 2octahedra arranged in zigzag chain along (221) diffraction plane, sharing by 4 edges [58].…”

A Novel Method to Control the Crystallographic‐Preferred Orientation of Lead Iodide Toward Highly Efficient and Large‐Area Perovskite Solar Cells

“…The PSCs based on PbI 2 synthesized with 10 wt% of acetic acid exhibited the best PCE of 20.22%. Elshimy et al [9] adopted mechanical milling treatment to obtain nano-sized PbI 2 powders to improve the quality of perovskite films. Afterward, the device of DOI: 10.1002/solr.202200609 Perovskite solar cells (PSCs) have been the promising stars in the solar cell industry for dramatically improving the power conversion efficiency (PCE) in the past decade and reaching a record over 25%.…”

“…The PSCs based on PbI 2 synthesized with 10 wt% of acetic acid exhibited the best PCE of 20.22%. Elshimy et al [ 9 ] adopted mechanical milling treatment to obtain nano‐sized PbI 2 powders to improve the quality of perovskite films. Afterward, the device of fluorine‐doped tin oxide (FTO)/titanium dioxide (TiO 2 )/MAPbI 3 /carbon was fabricated in the air via a two‐step dipping method, and the PSCs based on the milled and un‐milled PbI 2 powders achieved a PCE of 5.8% and 2.55%, respectively.…”
