In order to reduce energy consumption and to improve impact energy absorption, Ball-chain type Metallic Hollow Sphere (MHS) Structure which is a new ultra-light porous metals and can be used for compressive and bending energy absorption was developed.
The photo-responsive molecular devices for sensing an oxygen gas are manipulated on the basis of the thin film formation of clay minerals. In the attempts, luminescent Ir(III) complexes (guests) were hybridized with clay minerals (hosts) in order to enhance robustness and reliability. Nanometer-thick hybrid films were constructed by applying the modified Langmuir-Blodgett method to an aqueous dispersion of clay minerals as a subphase. The achievement of multi-emitting properties in response to the change of oxygen pressure is described.
New surfactants which are easily preparable in situ from lysine and aldehydes and conveniently degradable after working were developed. They worked well for emulsion polymerization. This technology furnished polystyrene with good quality.
Using the newly developed measurement system of intact angiotensinogen (AGT), together with the measurement system of total AGT, we are able to diagnose the disease state that mimics primary aldosteronism in an animal study.
Periodontitis is one of the most major life style-related diseases.The water extract of Igusa, which is a material of tatami mat, has an antibitic activity against periodantal bacteria and a preventive effect of inflammation for oral epithelial cells. We aim for the application of Igusa extract to oral health care products.
