This is bad, really bad. This would be catastrophic for our chemistry researchers. Not just going forward looking for a replacement product (hello Chemdoodle), but the inability to open ~30 years of documents, edit old schemes and thesis figures etc would be incalculable. Now currently thePerki...
You add concentrated hydrochloric acid drop-wise in the hood to Flask #1 until the contents are acidic to litmus and then cool the flask in an ice bath. What is the chemistry of the color change of th Which substance will dissolve in water to produce an acidic solution? (a...
The brain consists of some 100 billion nerve cells (give or take a few bil- lion). Each cell is connected to thousands of other nerve cells in an astonishingly complex network. In scientific terms, the brain is sometimes called 'the final frontier,' because its function is still not ...
An indicator is used in titrations to determine the endpoint experimentally and visually. Indicators change their color at the endpoint (or near the endpoint) so that the human eye can detect the change. The change in color occurs either due to a redox reaction or an acid-base ...
记得有一次周末很晚从LX家出来,A发来短信问我所在,我回说让她猜,她说,是在LX家吧?我奇道你如何猜到?她这样回答: Your life is organized like an orbit. I know. 了解了这点,就知道为何四年于相隔千里的我们,似乎只是弹指一挥间而已。 我其实了解小女儿的心理,是希望多一点surprise多一点romantic多一点傻...
aThis termination process is not exclusive of another bimolecular one due to the reaction with the polymer.The fact that the unimolecular process is predominant explains the good fit observed in Fig.7 with the exponential law. 这个终止过程不是专属的另一二分子一个由于反应与聚合物。事实单分子的...
I had to take an oral examination in Chemistry for Physicists after the third semester in 1973. Dieter Ziessow, a young assistant professor of Chem- istry, was my examiner. After the examination he asked me if I were interested in a research project with him. I accepted. He gave me a...

The functional activity is revealed by a flow of physiologically relevant inorganic ions, such as Na+, K+ and Cl−, across the BLM either from cyclic voltammetry (current-voltage curves in biophysical jargon) or chronoamperometry measurements (current-time curves) [3]. A major drawback of ...
