Glancing angle deposition

A naturally occurring chiral metal structure is a screw dislocation (Fig. 3.4),11 which is a chiral arrangement observed in metal crystals but never resolved and tested for enantioselective heterogeneous catalysis. A possible method of making chiral arrangements like screw dislocations is by the glancing angle deposition technique, which can produce chiral sculptured thin films.12...

In almost all cases, commercial HPTLC plates have been used with the TLC-MS interface. A few papers (e.g.. Reference 25) were published involving its use with commercial Merck ultrathin layers (UTLC) (introduced in 2001 and now discontinued), and, more recently, laboratory-made UTLC plates such as those produced by glancing angle deposition (GLAD) [26,27]. Layers for TLC-MS are covered in detail by Rabel in Chapter 5, and Table 3.1 lists layers used with the TLC-MS interface.
