Electrodes with hollow nanotubes improve performance of potassium-ion batteries
2023-10-27
Researchers who are working to find alternatives to lithium-ion batteries have turned their attention to potassium-ion batteries. Potassium is an abundant resource and the technology functions in much the same way as lithium-ion batteries, but these batteries have not been developed at a large scale because the ionic radius causes problems in energy storage and substandard electrochemical performance.   To solve this problem, researchers are considering NiCo2Se4, a bimetallic selenide, to create sphere-shaped electrodes. The spheres are constructed with NiCo2Se4 nanotubes, which improve ...

Common chemotherapy drugs don't work like doctors thought, with big implications for drug discovery

Common chemotherapy drugs dont work like doctors thought, with big implications for drug discovery
2023-10-27
A new study from the University of Wisconsin–Madison suggests that chemotherapy may not be reaching its full potential, in part because researchers and doctors have long misunderstood how some of the most common cancer drugs actually ward off tumors. For decades, researchers have believed that a class of drugs called microtubule poisons treat cancerous tumors by halting mitosis, or the division of cells. Now, a team of UW–Madison scientists has found that in patients, microtubule poisons don't actually stop cancer cells from dividing. Instead, these drugs alter ...
