One solution comprises one part ammonium hydroxide, two parts hydrogen peroxide, and 300-600 parts deionized water together with a trace of high purity surfactant. Rinsing water is flowed through the tank after the first solution is dumped. A second solution comprises highly dilute hydrofluoric acid...

The second method is to use the reaction of hydrogen with oxygen in a battery, making the car a kind of electric one. The dream of producing hydrogen in the car while driving along by electrolyzing(电解)water is a long way off, so we are still at the period of batteries and filling...
In this study we conducted the experiment using two hydrogen atomic clocks (noted as H-masers), namely CA and CB, respectively. The CA (VCH-1003A) is a fixed clock while CB (BM2101-02) is a portable clock. We adopt the Modified Allan Deviation (MDEV) to evaluate the frequency stabilit...
and absorption. There are also two-component liquid-gas systems where the gas is noncondensable; these include air/water flow in aeration, deaeration, and humidification or dehumidification processes. A biomedical engineering example is the development of artificial lungs where absorption of oxygen or ...
