Effects of Tacticity and Crystallinity on Phase Behavior of Binary Blends Based on Polypropylenes: iPP, sPP, and aPP
E. M. Woo

Phase behavior of two isomeric polymers, such as poly(vinyl acetate) (PVAc) and poly(methyl acrylate) (PMA) has been an interesting topic of studies.  In the literature, the PVAc/PMA blend system is proven miscible with a stable homogeneous phase,[1,2] where PVAc differs from but is a structural isomer to poly(methyl acrylate) (PMA).  On the other hands, ...

Diffraction characteristics of a liquid crystal polarization grating analyzed using the finite-difference time-domain method
Andy Y.-G. Fuh

Liquid crystal polarization grating (LCPG) is a new diffraction grating formed by an interference field of two laser beams with their polarizations being orthogonal. It is interesting because most of LCPGs exhibit unique diffraction characteristics, such as polarization-independence, low scattering and high diffractive efficiency. Therefore, these devices have attracted much attention because of ...

A Rule Based Assembly Sequence Generation Method for Product Design
Ming-Chyuan Lin

A feasible design alternative that follows the design rules for assembly will make product manufacturing and assembly more successful.  To assist designers to deal with the assembly issue in the design process, this research presents a contact relation matrix (CRM) approach to generate assembly sequences for product design.  The procedure developed for the CRM approach is based on the four rules ...

To die or not to die, that depends on the tissue environment: Tumor extracellular matrix shapes the Fas-meditated apoptosis in T cells.
Bei-Chang Yang

Apoptosis triggered by Fas (CD95, Apo1) receptor is one of the important ways to regulate the biological functions at cellular level. Delayed Fas-mediated apoptosis in immune cells associates with many pathological inflammatory consequences. During tumor formation, inadequate accumulation of infiltrating immune cells, mainly due to defective Fas death signaling, may play an adverse role. ...

Recrystallization of epitaxial GaN under indentation
S. Dhara

Suji Nakamura’s hard work found GaN as potential candidate for the blue light source around 365 nm for which he received the prestigious Millennium Technology Prize in 2006. Blue diode laser have the huge market for printing (1200 dpi having ~17 μm spot size with 1 mm depth of field using 6 mm optics), high density DVD memories and white light based (using diode laser based RGB) ...
