Quantitative Evaluation of the Baroreflex Sensitivity of the Heart and Artery

NEXT
PREV
Features

Metabolic syndrome is an important view point, when we consider the preventive medicine. Hypertension is one of the most important points to prevent the cardiovascular events. However, there is no method to measure the baroreflex sensitivity of the artery in the patients with hypertension. Tohoku University had invented the new method to evaluate the baroreflex sensitivity of the heart and artery (JP Patent No.4789203).

Targeted Application(s)/Industry

By the use of this machine, the baroreflex sensitivity of an artery in the patients can easily be measured noninvasively. It enables to predict the occurrence of hypertension and evaluate the therapy of hypertension easily, while allowing prevention of the cardiovascular events.

Quantum and Molecular Dynamic Simulations of Transport Phenomena in Fuel Cell

NEXT
PREV
Features

It is necessary to grasp nanoscale transport phenomena of materials in polymer electrolyte fuel cell to improve its performance. In our laboratory, nanoscale transport phenomena are analyzed by large scale molecular dynamics simulations using a supercomputer system. As the present theme, the dependence of the materials or structures of polymer electrolyte membrane on the ability of proton transfer(Fig. 1), the ability of proton transfer or oxygen permeability of ionomer in catalyst layer(Fig. 2), and the mechanism of transport phenomena of a water droplet in a nano pore in gas diffusion layer or micro porous layer(Fig. 3), are analyzed in detail.

Targeted Application(s)/Industry

These research can be applied to the analysis of flow field in devices which have nanoscale structure, for instance, fabrication process of semiconductor, friction phenomena of such nanoscale devices or next generation batteries, as well as the field of fuel cell.
