My Ph.D. supervisor just won the Nobel Prize in Chemistry for designing a safer, cheaper and faster way to build molecules and make medicine

October 12, 2021 No Comments

The reason that ibuprofen treats headaches and ice cream tastes sweet is that their chemical components fit perfectly into certain receptors in your body. The better a drug or flavor molecule fits with its matching receptor, the more effective the medicine or tastier the treat. But an interesting quirk of

New fabric could protect against both biological and chemical threats

October 11, 2021 No Comments

Credit: Northwestern University. A Northwestern University research team has developed a versatile composite fabric that can deactivate both biological threats, such as the novel coronavirus that causes COVID-19, and chemical threats, such as those used in chemical warfare. A material that is effective against both classes of threats is rare.

How the harmful mercury gets into the sea

October 4, 2021 No Comments

Credit: André Santana AndreMS/Pixabay. Every year, 2,000 metric tons of gaseous mercury are released into the atmosphere by coal-fired power stations and mining activities. The harmful substance then adopts various chemical forms as it circulates between the air, soil and water in a complex cycle. Mercury is particularly dangerous in

How flawed diamonds ‘lead’ to flawless quantum networks

October 3, 2021 No Comments

Credit: Dieter_G/Pixabay. The color in a diamond comes from a defect, or “vacancy,” where there is a missing carbon atom in the crystal lattice. Vacancies have long been of interest to electronics researchers because they can be used as ‘quantum nodes’ or points that make up a quantum network for
