The Era Beyond Fluorescence and Phosphorescence – Thermally Activated Delayed Fluorescence
Advances in knowledge about light emission have brought breathtaking innovations in lighting and display technologies. The well-known light-emitting processes are fluorescence and phosphorescence. Let’s take a closer look into their dynamics and another light-emitting process: Thermally Activated Delayed Fluorescence (TADF)!
A Simple Approach for Developing Inexpensive and Sustainable Metal Catalysts
In order to keep catalyst-based industries sustainable and profitable, new catalysts need to be developed that utilize inexpensive, earth-abundant materials. The authors here present a novel method for easily forming stable earth-abundant metal catalysts, which are inexpensive and sustainable alternatives to precious-metal catalysts.

Continuing the pesticide analysis journey: peeking into different LC-MS instrumentation
This article will be focusing on a very commonly used instrumentation, Liquid Chromatography-mass spectrometry (LC-MS). Who wins in the battle between LC-QqQ, QTOF, TOF?
Using Biology to Harness the Power of Fluorine Chemistry
What comes to mind when you think of fluorine? The sodium fluoride in toothpaste and mouthwash is the typical, everyday example that most people think of, but fluorine plays a large role in many other compounds. Pure fluorine is a highly reactive and poisonous gas, while fluorinated compounds are incredibly stable, fairly nontoxic, and used in many real-life applications.
How much pesticides are in your food? – Sample preparation in a nutshell
How do we know we are safe with what we eat? Here, the authors introduce a fast and easy way to dig out the pesticides from our food for analysis.
Stacks on stacks on stacks
Finding ways to create order is a common theme in science. Here researchers are trying to carefully arrange chromophores in order to create better solar cells (among other potential uses). In particular, these chemists are trying to make porphyrins stand up on a surface creating stacks of porphyrins that are a well defined distance from each other and from the surface they are attached to.
“Chemical-free”
Here the authors describe all of the consumer products that are utterly and completely chemical-free. I hate to ruin the surprise, but their aren’t any.
Can adding calcium help forests?
This study further supports a connection between acid deposition and forest decline. The authors state, “Continued vigilance in the control of acid rain precursors will be needed to correct these problems, and aggressive options to reduce pollution in rapidly industrializing regions of Latin America, Asia, and Africa are warranted.”
Questions are raised about “unclick” reaction
Click chemistry, a term used to describe a number of high yield reactions, is used far and wide by chemists. The azide alkyne Huisgen cycloaddition typifies click chemistry and awhile back, I described it as my favorite reaction.
