1H-1,2,4-Triazole-3-carboxamide [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2008
Planar mol-ecules of the title compound, C(3)H(4)N(4)O, are organized into sheets by extensive N-H⋯O and N-H⋯N hydrogen bonding in the (101) plane of the crystal structure. These hydrogen bonds may also stabilize the mol-ecule in the Z form. The title compound is in the amide form, as shown by the C=O bond length [1.252 (2) Å].

Site‐Selective Polyvinylpyrrolidone Adsorption Behavior for 3D Heterogeneous Integration

open access: yesAdvanced Materials Technologies, EarlyView.
Site‐selective adsorption behavior is presented with polyvinylpyrrolidone on a Cu/SiO2 pattern wafer, which enables 3D heterogeneous integration. Owing to the site‐selective adsorption behavior and its corresponding electrostatic interaction between SiO2 nanoparticles and the Cu surface, the selectivity of Cu/SiO2 is arbitrarily controlled ...
