I’m basically an explorer. Even if exploration doesn’t come naturally to you, I believe scientists of every temperament can learn to explore. I'd like to help everyone here become more creative, more open to oppo...
We have to assume that chemistry is chemistry, and that physiology or medicine is sort of biology. If there is a discovery in biochemistry, the decision is very difficult whether it should be awarded the chemistry prize or the physiology or medicine prize.” At some point, it has been ...
the only metal oxide, and six metal salts, namely zinc, magnesium, and copper sulfate, together with copper, zinc, and manganese gluconate, the metal salt of gluconic acid, a naturally occurring carboxylic acid which increases the bioavailability of metals, whose chemical structures are featured in...
In the game, the manufacturer produces both brown and green products, and the green product is sold to the final consumer through two channel structures: direct selling or agent selling. This paper explores manufacturers’ channel selection strategies and considers the impact of key factors such as...
Lewis structures provide you with a simple way to draw out an organic molecule showing every atom, bond, and lone electron pair. While not ideal for demonstrating bond angle and molecular geometry, it's a great way to begin your understanding of molecules and bonding in organic chemistry. ...
Thus, in chemistry, it's acceptable to interchange weight with mass. The equivalent weight of an element is its atomic weight (also known as atomic mass) divided by its valence (combining power or number of electrons in the outer shell available for chemical bond formation). It's the ...
Thioether, as the name implies, is a thio (or sulfur) version of the ether. As we’ll see shortly, ethers have an oxygen between 2 carbon atoms. Thioethers have a sulfur (rather than oxygen) between 2 carbon atoms. To recognize this functional group in organic molecules, look for a ca...
When you learn chemistry, it's much more important to understand the concepts than to memorize structures, elements, and formulas. However, rote memorization has its place, particularly when you arelearning functional groups(or other organic chemistry molecules) and when you're trying to keep name...
The name Markush comes from patent-law history, but the structures are used in many other contexts. From the first R-group you saw in an organic chemistry textbook, or the first structure you drew with variable repeats, you’ve worked with Markush structures. ...
When it comes to academic research, choosing the right chemistry topic is crucial. A well-selected topic aligns with your interests and contributes to current scientific discussions, allowing you to make meaningful contributions to the field. Whether you're interested in organic chemistry, physical ...
