To find the effects of cross-linker phenol-formaldehyde (PF) resin on the performance of soy-based adhesives, the reaction between model compounds hydroxymethyl phenol (HPF) and glutamic acid were studied in this paper. HPF prepared in laboratory conditions showed higher content of hydroxymethyl groups than normal PF resin, which was proved by the results of Electrospray Ionization Mass Spectrometry (ESI-MS) and 13C Nuclear Magnetic Resonance (13C-NMR). The results of ESI-MS, Fourier transform infrared spectroscopy (FT-IR), and 13C-NMR based on resultant products obtained from model compounds showed better water resistance of the soy protein-based adhesive modified by PF-based resin, which indicated the reaction between PF resin and soy protein. However, it seemed that the soy-based adhesive cross-linked by HPF with the maximum content of hydroxymethyl groups did not show the best water resistance.

4,6-Dinitro-7-(thiazol-2-ylamino)benzo[c][1,2,5]oxadiazole 1-oxide was synthesized by a SNAr reaction between 7-chloro-4,6-dinitrobenzofuroxan and 2-aminothiazole. The structure of the newly synthesized compound (45% yield) was elucidated based on 1H-NMR, 13C-NMR, NOESY-1D, ESI-MS, UV-Vis, and FT-IR techniques.

The substituted phenanthrenequinone thiosemicarbazones (HL1, HL2 and HL3), and their metal complexes (M = Ru(II) or Zn(II); SM1, SM2, SM3 and SM4) were synthesized and characterized by FT-IR, 1H & 13C NMR and ESI-MS. The spectral data IR, 1H & 13C NMR and ESI-MS indicates two tridentate ligands coordinating in the form of an octahedral geometry. The gas phase geometry of all the zinc(II) and ruthenium(II) complexes was carried by using density functional theory (DFT). The antimycobacterial susceptibility testing at 100 μM of the complexes using resazurin microtiter plate assay resulted in growth inhibition. Complexes SM2, SM3 and SM4 showed good antimycobacterial activity at 100 μM concentration by using rifampicin as inhibition control.
