Single-chain mechanical property of poly (N-vinyl-2-pyrrolidone) and interaction with small molecules

Article Abstract:

Atomic force microscopy based technique-single molecule force spectroscopy was used for examining the single-chain nanomechanical properties of poly (N-vinyl-2-pyrrolidone) (PVPr) and povidone-iodine (PVPr-I2) under different solution conditions. The force-extension curve (force curve) of PVPr in water is deviated from that obtained in ethanol or tetrahydrofuran.

Thermal properties of Bi nanowire arrays with different orientations and diameters

Article Abstract:

Diffractional scanning calorimeter and in situ high-temperature X-ray diffraction are used to study the thermal properties of single-crystalline Bi nanowire arrays with different orientations and diameters. The results have shown that the physical properties of Bi nanowires depend strongly on the orientation of the nanowires.
