Tau aggregation inhibitor

A tau aggregation inhibitor reduces tau aggregation in cells. The tau aggregation inhibitor can include a catechol structure-containing compound or a salt thereof, and the catechol structure-containing compound can be one of isoprenaline, dopamine, dobutamine, levodopa, levodopa/carbidopa, trimetoquinol, hexoprenaline, methyldopa, and droxidopa. ...

Liquid-crystal varifocal lens and focal length control method

A liquid-crystal varifocal lens includes a liquid crystal lens, and an ultrasonic transducer for generating an ultrasonic wave with a frequency that matches a resonant frequency of the liquid crystal lens. The ultrasonic transducer generates flexural oscillation in the liquid crystal lens such that the flexural oscillation has a vibration intensity decreasing continuously from the center to the circumference of a liquid crystal layer, whereby the thickness of the liquid crystal layer is changed, with the result that the orientation of the liquid crystal molecules is changed.. ...

Magnetic material and production method therefor

A production method for a magnetic material, which is expressed by a chemical structure formula fe(al1−xmnx)2o4, where 0<x<1, and exhibits ferromagnetism, includes: preparing a mixed aqueous solution by dissolving, in distilled water, fe nitrate, al nitrate, and an oxide including mn, the fe nitrate, the al nitrate, and the oxide being parent materials; preparing a metal-citric acid complex by mixing citric acid and ethylene glycol with the mixed aqueous solution; obtaining a precursor by boiling the metal-citric acid complex to a gel and drying the gel; and obtaining the magnetic material by sintering the precursor.. . ... The Doshisha

Metal electrowinning anode and electrowinning method

An electrowinning system is provided that is capable of suppressing accumulation of a side reaction product on an anode and a rise of an electrolysis voltage caused thereby, and an electrowinning method is provided using the system. To solve this problem, the electrowinning system of the present invention applies predetermined electrolysis current between an anode and a cathode placed in an electrolyte, thereby depositing a desired metal on the cathode, in which the electrolyte is a sulfuric acid-based or chloride-based solution containing ions of the metal, and the anode has a catalytic layer, containing amorphous iridium oxide or amorphous ruthenium oxide, formed on a conductive substrate.. ... The Doshisha

Ion sensor catalyst, ion sensor using same, and quantification method

An inexpensive ion sensor catalyst capable of detecting hydrogen phosphate ions in water and determining hydrogen phosphate ion concentration on the basis of oxidation current density for the ions, along with an ion sensor and a quantification method, the ion sensor catalyst being characterized by providing higher detection sensitivity than conventional ion sensor catalysts, being capable of maintaining high detection sensitivity over a wide range of hydrogen phosphate ion concentration, achieving a proportional relationship between concentration and oxidation current density, so that the concentration can be determined with accuracy regardless of the concentration range, and allowing oxidation current to reach a steady-state value in a short time, so that time to determine current density is short, resulting in shortened time to quantify hydrogen phosphate ions, and stable response to hydrogen phosphate ion oxidation can be made repeatedly.. . ...
