Growth of metallic Ag whisker single crystals on AgI films

The growth of silver whisker nanocrystals (WNCs) on the surface of an AgI film deposited by laser ablation is studied on a Zeiss Merlin scanning electron microscope. The chemical composition of WNCs is determined by electron-probe microanalysis. The growth rate of WNCs is estimated. Possible WNC growth mechanisms under the action of an electron beam are considered.     

Estimation of the size of drug-like chemical space based on GDB-17 data

The goal of this paper is to estimate the number of realistic drug-like molecules which could ever be synthesized. Unlike previous studies based on exhaustive enumeration of molecular graphs or on combinatorial enumeration preselected fragments, we used results of constrained graphs enumeration by Reymond to establish a correlation between the number of generated structures (M) and the number of heavy atoms (N): logM = 0.584 × N × logN + 0.356. The number of atoms limiting drug-like chemical space of molecules which follow Lipinsky’s rules (N = 36) has been obtained from the analysis of the PubChem database. This results in M ≈ 10³³ which is in between the numbers estimated by Ertl (10²³) and by Bohacek (10⁶⁰).
