The process of naming compounds allows chemists to communicate formulae in words rather than in chemical symbols. There are, however, a few rules about naming compounds which need to be known in order to write a formula in word form or translate a compound in word form into chemical symbols. Ionic compounds If the compound […]

“Better living through better chemistry” Chemistry affects our lives in many different ways, everyday. The air you inhale everyday is an element called hydrogen. Chemistry affects us in good ways and bad ways. So, I decided to do it in both points of view. Without chemistry our lives wouldn’t be as easy it is right […]

Research question: Does the concentration (mol DMS) of sulfur dioxide in wine rise or fall when exposed to alarm for different time periods (O, 75,150,225, 300 minutes)? Purpose: Many adults enjoy the consumption of wine but are not aware of the different preservatives and chemicals that are added to the drink. Sulfur Dioxide, which is […]

CHEM. RES. CHINESE UNIVERSITIES China Abstract A sensitive, simple, and low-cost method based on capillary electrophoresis(CE) with electrochemical(EC) detection at a carbon fiber microdisk electrode(CFE) was developed for the determination of nicotine. The effects of detection potential, concentration, and pH value of the phosphate buffer, and injection time, as well as separation voltage, were investigated. […]

In 2014, the Nobel Prize in Chemistry was awarded to Eric Betzig and William Moerner who, working separately, laid the foundation for SMLM. In essence, this method relies on the possibility to turn the fluorescence of individual molecules on and off. Scientists image the same area multiple times, allowing only a few interspersed molecules to […]
