Internal friction investigation of phase transformation in nearly stoichiometric LaMnO3+δ [PDF]

, 2005
Rhombohedral LaMnO3+δ powders, prepared by two different soft chemistry routes (co-precipitation and hydrothermal synthesis), are sintered at 1400 °C for 2 h in air. Measurements of internal friction Q−1(T) and shear modulus G(T), at low frequencies from

Pushing the Limits of Solid-Phase Peptide Synthesis with Continuous Flow

, 2018
Since its invention by Bruce Merrifield, solid-phase peptide synthesis has conventionally been performed in batch reactors. With systems created by Atherton, Dryland, and Sheppard in the 1980s, flow-chemistry techniques began to be applied to enhance ...
