Nuts, on the other hand, serve as the complementary part to bolts. When tightened onto a bolt, they provide the necessary clamping force to hold components together, ensuring stability and resistance against dynamic forces such as wind, earthquakes, or the weight of the structure itself. The choice of nut, whether it's a hex nut, wing nut, or castle nut, is determined by factors like accessibility, safety considerations, and the need for locking mechanisms.

  • The versatility of HPMC lies in its ability to adjust its properties based on the degree of methylation and hydroxypropylation
  • One of the most significant advantages of HEC is its ability to form hydrogels. Hydrogels are three-dimensional networks of hydrophilic polymers that can absorb and retain large amounts of water. This property makes HEC an excellent material for drug delivery systems, as it can be used to control the release of drugs over a desired period. HEC hydrogels have also been used in the development of contact lenses, wound dressings, and tissue engineering scaffolds.
