    Poly(γ-benzyl L-glutamate), partially transesterified with 1-dodecanol, and polysiloxane were employed to fabricate a right- and left-handed optical element, respectively. The wavelength of selective reflection was tuned via physical blending or annealing at a proper temperature. An optical notch filter comprising elements with each handedness showed an optical density of 2.0 within the rejection band and 73 to 83% transmission outside the band, suggesting liquid crystalline polymers as promising materials for the construction of environmentally robust optical notch filters.

    Abstract Specimens of investment-cast Mar-M247 superalloy were vacuum-plasma sprayed with Co-29Cr-6Al-1Y bond coat, and part of the specimens were further pre-aluminized at 980°C for 2, 4, 6, 8, and 10 hours. All the specimens were then deposited with ZrO2-8 wt.% Y2O3 thermal-barrier coatings (TBCs) and thermally cycled at 1050°C to evaluate the effect of time of the prealuminizing treatment on the performance and failure mechanism of the modified system. Results showed that TBC specimens with pre-aluminized bond coatings exhibited lower oxidation rates and significantly higher cyclic life when compared with unaluminized specimens. The failure of bond-coat pre-aluminized TBC specimens was observed to propagate mainly along the lamellar splats of the top coat, whereas the failure of conventional TBC specimens occurred mainly along the top-coat/spinel oxides interface.

    Notes:
    Abstract The thermotropic and optical properties of methacrylate copolymers and chemically modified poly(γ-benzyl L-glutamate) were investigated as part of our effort to explore the optical applications of these materials. It was found that besides the commonly cited comonomer ratio, physical blending and annealing followed by quenching represent a new and more flexible means to tune the selective reflection wavelength. In the chemically modified poly(γ-benzyl L-glutamate) system with Tg as low as — 25 °C, it appears that the relatively high-melt viscosity is capable of sustaining the cholesteric mesophase, generated by annealing and quenching, while subjected to heating up to 100°C.
