Metal-Incorporated Mesoporous Silicates: Tunable Catalytic Properties and Applications
Molecules, 2018 A relatively new class of three-dimensional ordered mesoporous silicates, KIT-6, incorporated with Earth-abundant metals such as Zr, Nb, and W (termed as M-KIT-6), show remarkable tunability of acidity and metal dispersion depending on the metal content,

Late‐Stage Functionalization of Peptides on the Solid Phase
Angewandte Chemie International Edition, EarlyView.Peptide modifications are essential to control pharmacodynamic and pharmacokinetic properties of peptide drugs. Consequently, strategies that allow for efficient and rapid incorporation of non‐canonical modifications into peptides in parallel formats are highly sought after.
