PVC glue, also known as PVC cement or solvent cement, is a specialized adhesive used for bonding PVC pipes and fittings in plumbing and construction applications. The glue contains solvents that dissolve a thin layer of the PVC surface, effectively welding the pieces together as it dries. This chemical reaction ensures a strong, waterproof seal that can handle high pressure, making it ideal for both residential and commercial piping systems. Proper application involves cleaning the joining surfaces, applying the glue evenly, and quickly assembling the parts before it dries. It's crucial to use PVC glue in a well-ventilated area due to its strong fumes.

If a lithium-ion polymer (LiPo) battery gets wet, it could lead to serious safety issues. Water can react with the lithium, potentially causing short circuits, swelling, or even fires and explosions due to rapid heat release and gas expansion. It's crucial to immediately turn off the device (if possible) and disconnect the battery (with caution). Do not charge or attempt to use a wet LiPo battery. Instead, place it in a non-conductive and fireproof container and consult a professional for disposal advice. To prevent such instances, always ensure your LiPo batteries and devices are stored and used in dry environments and are adequately protected against moisture exposure.

There are three crystalline forms of titanium dioxide in nature: rutile. anatase. and plagioclase. Rutile and anatase are the most commonly used commercially.
