The study of organic reactions will continue from CHEM 0203 with radical reactions, alkene and alkyne additions, aromatic reactions, oxidations and reductions, and additional carbonyl reactions.

Using chemical reactions, the team successfully generated aromatic carbons and hydrogen from their lignin jet fuel, an experimental fuel formulated on the foundation of lignin—an organic polymer ...

Reactions to a recent immunization (vaccine) Most are reactions at the shot site (such as pain, swelling, redness) General reactions (such as a fever or being fussy) may also occur ...

As there is no known natural enzyme that could catalyze S N Ar reactions, the team initially ... Engineered enzymes for enantioselective nucleophilic aromatic substitutions, Nature (2025).

Allergies are an immune system reaction to substances called allergens. The cause a range of symptoms from a stuffy nose to itchy eyes to difficulty breathing. How long allergies last varies based on ...

A change is called irreversible if it cannot be changed back again. Many chemical reactions are irreversible. In a chemical reaction, new materials are always formed. Sometimes these new materials ...

Reaction formation may be a temporary coping mechanism, but it’s unproductive in the long run. It ignores underlying beliefs or challenges that need to be addressed, which can hurt mental health.

Our research is motivated by a desire to understand how catalytic process occur at the detailed molecular level. In particular, we study palladium-catalyzed allylic-addition reactions and explore the ...

Quick reactions and selfie stickers have been added to make responding and creating stickers easier. The first update comes to the camera effects feature, which is now expanding the tools ...
