[long fatigue life]

Novel CoCr-based superelastic metallic biomaterial with low Young's modulus

NEXT
PREV
特徴・独自性
  • General metallic biomaterials, such as stainless steels and conventional CoCr alloys, show a high Young's modulus ten times higher than that of human bones. This is an unfavored feature because it causes the so-called "stress shielding effect" when they are used as implants. β-type Ti alloys have a relatively lower Young's modulus, but they come with a compromise of low wear resistance. The current novel CoCr-based alloys are a breakthrough; they exhibit both a low Young's modulus similar to human bones and a high wear and corrosion resistance. Moreover, they exhibit superelasticity with a huge recoverable strain over 17%, also showing promise as shape memory alloys.
実用化イメージ

It is the first time that a low Young's modulus, a high corrosion and wear resistance, and a superior superelastic behavior are simultaneously obtained in a single material. The current novel CoCr-based alloys are promising for biomedical applications such as total hip or knee joint replacements, bone plates, spinal fixation devices, and vascular stents.

[low-temperature injury]

Methods to Restore Strelity of Gramineous Plants under High- and Low-Temperature Stress Conditions

NEXT
PREV
特徴・独自性
  • Plant reproductive development is more sensitive than vegetative growth to many environmental stresses. High-temperature injury is becoming an increasingly serious problem due to recent global warming. In wheat, barley, and other crops, the early phase of anther development is most susceptible to high temperature. Oppositely, grain yields in rice plants are often reduced by exposure to low temperature. Unexpected climate change, such as abnormally hot or cool summer temperatures, have occurred repeatedly during recent years. This method indicates that an appropriate use of specific phytohormones, such as auxin and GA, may promote stress tolerance and adaptation to abiotic stresses.
実用化イメージ

These potentially novel functions of the classical phytohormones will be important sustainable agriculture in the face of global climate change.

Development of High Performance Carbon Nanotube-Alumina Composite

NEXT
PREV
特徴・独自性
  • One of the important challenges in the development of carbon nanotubes (CNTs) reinforced ceramic composites is uniform dispersion of CNTs in the matrix. The mechanical properties of CNT/ceramics composites have been limited to date due to the formation of CNT agglomerates in the composite. We have successfully produced CNT/alumina composites with world top class strength and toughness, by employing a newly developed CNTs dispersion technique based on a flocculation method. The processing method developed in this study enables us to prepare high performance CNT materials using a pressureless sintering method.
