How small changes to methylated piperidinium cations impact the synthesis of zeolite SSZ‐39

AIChE Journal, EarlyView.
Abstract Here we report a synthesis study of SSZ‐39 with four different organic structure directing agents (OSDA). The goal was to determine how subtle changes to the OSDA architecture impact crystallization kinetics, material composition, and other properties.

a-Si:H crystallization from isothermal annealing and its dependence on the substrate used

, 2010
We present hydrogenated amorphous silicon (a-Si:H) films which were deposited on two different substrates (glass and mono-crystalline silicon) after an isothermal annealing treatment at 250 ◦C for up to 14 h.

Tuning Pore Geometry of Zirconium Metal–Organic Frameworks via Bent Ligands for Enhanced Sulfide Oxidation Catalysis

Angewandte Chemie, EarlyView.
Engineering pore geometry through ligand conformational bending enhances active‐site accessibility and mass transport in Zr‐MOFs, leading to superior catalytic sulfide oxidation. ABSTRACT Pore engineering represents a powerful strategy to tailor the physicochemical properties of metal–organic frameworks (MOFs), yet the structure‐activity relationship ...
