Structural Basis of MicroRNA Biogenesis by Dicer-1 and Its Partner Protein Loqs-PB
bioRxiv, 2022 In animals and plants, Dicer enzymes collaborate with double-stranded RNA-binding proteins to convert precursor-microRNAs (pre-miRNAs) into miRNA duplexes. We report six cryo-EM structures of Drosophila Dicer-1 and its partner Loqs-PB.

International Journal of Energy Research, 2021 This study presents some physical properties of fluoroperovskite NaQF3 (Q = Ag, Pb, Rh, and Ru) compounds computed with the help of the first‐principle study. Fundamental structural features, ie, basic structural parameters, are investigated and reported,

Surface Phase Transitions Induced by Electron Mediated Adatom-Adatom Interaction [PDF]
, 2003 We propose that the indirect adatom-adatom interaction mediated by the conduction electrons of a metallic surface is responsible for the $\sqrt{3}\times \sqrt{3}\Leftrightarrow 3\times 3$ structural phase transitions observed in Sn/Ge (111) and Pb/Ge ...

Cubic lead perovskite PbMoO3 with anomalous metallic behavior [PDF]
, 2017 A previously unreported Pb-based perovskite PbMoO$_3$ is obtained by high-pressure and high-temperature synthesis. This material crystallizes in the $Pm\bar{3}m$ cubic structure at room temperature, making it distinct from typical Pb-based perovskite ...

Structural and ferroelectric properties of perovskite Pb(1−x)(K0.5Sm0.5)xTiO3 ceramics [PDF]
, 2017 PbTiO3 has the highest tetragonal distortion (c/a ∼ 1.064) and highest spontaneous polarization among perovskite titanates. But, it is hazardous and hence one needs to reduce Pb content by substituting or reducing Pb content for use in practical ...
