Oil seals work by creating a tight seal around the rotating shaft. This prevents oil and other fluids from escaping while allowing the shaft to rotate smoothly. The seal is usually made up of a lip that fits snugly against the shaft, preventing any leaks from occurring. Some oil seals also have additional features, such as springs or gaskets, to provide extra support and ensure a secure fit.

In the realm of material science and manufacturing, plastic fillers play a vital role in enhancing the properties of polymer-based products. Fillers are substances added to plastics to improve their performance, reduce costs, and achieve desired physical properties. They can be broadly classified into two categories unintentionally added inert fillers, which are primarily used to reduce manufacturing costs, and intentionally added functional fillers, which are designed to enhance certain characteristics of the end product.
Another fascinating example is the application of small-molecule APIs in the treatment of infectious diseases. Malaria, for instance, has been a global health challenge, prompting the development of effective small-molecule drugs such as artemisinin and its derivatives. These APIs, derived from the sweet wormwood plant, have become vital in the malaria treatment arsenal, showcasing the importance of natural products in API development. Advanced synthesis techniques and drug formulation strategies have further enhanced these molecules' efficacy, leading to better patient adherence and outcomes.
