Mobilities of ions in air

Mobilities of Ions in Air, Hydrogen, and Nitrogen.

Preliminary communication. s The paper will appear shortly in Science, New York, N. S., 1918. All the precautions mentioned in this account were carefully observed in the present investigation. 3 The methods previously used in studying the photosynthesis of aquatic plants are not as accurate as the one here described, nor do previous experiments afford the kind of data needed for our purpose.

ساخت الکترودهاِی اصلاح شده ِیکِی از چالشهاِی همِیشگِی در دانش شیمِی بوِیژه شیمِی تجزیه مِی باشد ،که با در نظر گرفتن سادگِی ساخت، کاربردی بودن و ارزان بودن روش مِی توان به باارزش بودن چنِین سنسورهاِی پِی برد.آنچه که در ادامه آورده شده به ساخت و کاربرد الکترودهاِی اصلاح شده با استفاده از نانو ذرات در اندازه گِیرِی ولتامترِی آهن وکادمِیم اشاره دارد. کار اول اختصاص دارد به ساخت الکترود خمِیر کربن اصلاح شده با لِیگاند داِ...

Mobilities of positive ions in some gas mixtures used in proportional and drift chambers

2014 We have measured the mobility of positive ions in several gas mixtures frequently used in proportional and drift chambers, namely Ar-(OCH3)2CH2, Ar-(OCH3)2CH2-IsoC4H10, Ar-CH4, and Ar-CO2. In all gas mixtures considered, Blanc’s law of positive ion mobility has been verified, except for a very small methylal concentration in argon-isobutane-methylal. The law permits the calculation of ion ...

Air ions and human performance.

Air Ions and Physiological Function

Although gaseous ions possess no obvious physical properties which would predict a capability to influence living cells or tissues they can be shown to produce functional changes. The physiological effects so far demonstrated are limited in extent. In the mammalian trachea air ion action appears to depend upon the release of bound 5-hydroxytryptamine by CO(2) (+) and upon O(-)-induced accelerat...
