This Design Idea utilizes an optical computer mouse's sensor for measuring rotation of a disk which can be mechanically connected to any sort of rotating apparatus. One feature is to allow adjustment ...

Tartaric acid, a naturally occurring dicarboxylic acid found in many plants, most notably grapes, exhibits a fascinating ...

Basic polarimeters are comprised of a light source, two polarizing filters, an eyepiece for direct observation of optical rotation and a sample tube containing a solvent of interest. This phenomenon ...

In work that could aid predictions of unknown molecules' spectroscopic and other physical properties, researchers have measured optical rotation by an achiral organic compound. A prevalent ...

Gyroscope designs used in inertial navigation systems (INS) fall into three basic groups: the classic spinning-rotor mechanical gyro (still in use in specialized situations due to its superior ...

Chiral media exhibit optical phenomena that provide distinctive responses from opposite circular polarizations. The disparity between these responses can be optimized by structurally engineering ...
