The time delay of photoelectron emission serves as a fundamental building block to understand the ultrafast electron dynamics in strong-field physics. Here, we study angular streaking CO molecules by using two-color ( 400 + 800 nm) corotating circularly pola...

An experimental study of the oxidation of CO in exhaust gas from a motorcycle has been carried out using plasma chemical reactions in a pulsed corona discharge. In the process, some main parameters, such as the initial CO concentration, amplitude and frequency of pulses, residence time, reactor volume, and relative humidity (RH), as well as their effects on CO removal characteristics, were inve...

A 'first-passage-time' analysis is applied to enzyme kinetics. It is shown that the residence times determined in this way are directly related to the steady-state parameters and are particularly useful in analysis of isotopic exchange. A simple linear means is used for the calculation of these residence times that makes this method easily applicable to the numerical evaluation of complex model...

       In recent decades, most of researchers in pharmaceutical preparations have focused increasingly on new formulations that control the site and amount of drug delivery. Mucoadhesive dosage forms are available for systemic or local treatment. The mucoadhesive dosage forms are introduced in various forms such as tablets, gels, ointments, patches and polymeric films. For buccal wound and inju...
