1. Introduction to Molecular Sieves 1.1 What is a molecular sieve? A molecular sieve is a porous solid material whose pores (or “cages” / “channels”) have well-defined and extremely uniform diameters on the molecular scale (typically 3–10). Because of this, the material can selectively adsorb or exclude molecules based on their kinetic diameter (size), shape,

Introduction to Photoinitiator 127 Photoinitiator 127, also known by trade names such as Omnirad 127 or Irgacure 127, is a difunctional α-hydroxyketone (AHK) photoinitiator widely used in ultraviolet (UV)-curable systems. This compound plays a vital role in initiating free-radical polymerization upon exposure to UV light, allowing for rapid curing of coatings, inks, adhesives, and related
