Measurement of refractive index change induced by dark reaction of photopolymer with digital holographic quantitative phase microscopy
Autor: Wataru Watanabe, Takashi Fukuda, Hidenobu Arimoto, Kazuyoshi Masaki
Publikováno v: Optics Communications. 285:4911-4917
Light-induced refractive index change in photopolymer is quantified by a digital holographic microscope. The refractive index change is induced as the dark reaction which proceeds inside the photopolymer after a writing beam is stopped. Time-lapse ph

Publikováno v: Ferroelectrics. 343:119-125
We have prepared new all-organic ferroelectric liquid crystalline materials containing a polar and dichiral cyclic-nitroxide unit within the rigid core. These compounds show distinct ferroelectricity in SmC* phases. The spontaneous polarization (Ps)

Enzymatic screening of microalgae as a potential source of natural antioxidants
Autor: Isao Karube, Kazuyoshi Masaki, Zvy Dubinsky, Toshifumi Takeuchi, Ritsuko Matsukawa
Publikováno v: Applied Biochemistry and Biotechnology. 66:239-247
Extracts of over 100 species of microalgae both from nature and from laboratory cultures were screened for antioxidant activity. As an assay for antioxidant function, we examined the inhibition of the activity of two oxidizing enzymes, lipoxygenase a

Publikováno v: Journal of Applied Phycology. 9:29-35
The inhibition of lipid peroxidation and radical scavenging effects were studied to evaluate the antioxidant activity for extracts of 17 species of seaweed. The antioxidant effect was evaluated by determination of lipoxygenase activity and by α, α-

Publikováno v: 2011 ICO International Conference on Information Photonics.
Development of a polarization-sensitive material is one of the approaches for the improvement of storage capacity of the holographic memory by using the polarization state in addition to the intensity of light. A feasibility study of our polarization
