Nonstick pans. Pizza boxes. Even food itself. It’s impossible to avoid PFAS and BPA entirely, but experts have tips on how to limit your exposure.
I stand corrected and my apologize for the error, but it changes things only very little. If Fluorite was meaningfully better, one would think that AP would have used it as a mainstay in its product lineup rather than in couple of models. Also, in an amature market where people will sp...
If atoms are so tiny, there must be zillions and zillions of them in all the things around us... but how many are there, exactly? Chemists have a handy way of talking amount these vast numbers of atoms—by using the rather unusual word mole. A mole of something (anything) has exactly...
Fluorine-18 g. Americium-241 What is the name of period seven elements that are radioactive? What are the nuclear processes used to power commercial nuclear reactors and provide electricity? What are the waste products, and why are they so dangerous? Describe the three basic types of radio...
Per- and polyfluoroalkyl substances (PFAS) is a term often used to represent a diverse group of chemistries that contain carbon-fluorine bonds, the strongest chemical bonds in organic chemistry. Due to their unique and useful properties, PFAS are widely used and critical to enabling numerous tech...
What physical properties of calcium chloride, citric acid, sodium iodide, potassium iodide, and sucrose have in common? What is the positive valence of Sodium Sulfate (Na_2SO_4) ? What is the role of potassium in living things? What are the possible effects if too much or too little of...
Additionally, the new zoom features Moisture-Resistant Construction and Fluorine Coating. The easy handling provided by its compact size makes it a great choice for active scenarios such as mountain climbing or other outdoor activities. 4. Fast and accurate AF for still and video shooting The ...

We have listened and are thrilled to bring the new capabilities of the Alpha 9 III to market---capabilities which allow photographers to capture things they’ve never been able to capture before." Cheng continued, "For professionals everywhere, they can achieve even more dynamic expressions when...
Chemistry has been called the science of what things are. Its intent is the exploration of the nature of the materials that fabricate our physical environment, why they hold the different properties that depict them, how their atomic structure may be fathomed, and how they may be manipulated ...
