Isoxazolinyl Spironucleosides by Nitrile Oxide Cycloadditions to 7-Methylenepyrrolo[1,2-c]pyrimidin-1(5H)-one

The isoxazolinyl spironucleoside, bearing a primary hydroxymethyl group in C-3 position of the isoxazolinyl ring, was prepared from TBDPS substituted 6,7-dihydro-5-hydroxy-3-methoxy-7-methylenepyrrolo[1,2-c]pyrimidin-1(5H)-one.

In The Direction of Perfect Design of Self-Assembled Monolayers: Scanning Tunneling Microscopy Study of SAMs Made of Decanethiol on Au(111)

The self-assembled monolayers (SAM's)of decanthiol (C10) on Au(III) using scanning tunneling microscope (STM) at different preparation temperatures showed the formation of highly ordered monolayers in the temperature range (298-333)KO. The rotational ordered domains and depression increase in size with temperature.

Miscibility, Crystallinity and Morphology of Polymer Blends of
Polyamide-6/ Poly (

Blending of polyamide-6 (PA6) with bacterial poly (-hydroxybutyrate) (PHB) is studied.  Ellis approach has been improved to calculate the segmental interaction parameter. Crystallinity, miscibility and morphology of the blends have been investigated at different weight fractions and different crystallization temperatures.
