Bone cements have been used very successfully to anchor artificial joints (hip joints, knee joints, shoulder and elbow joints) for more than half a century. Artificial joints (referred to as prostheses) are anchored with bone cement. The bone cement fills the free space between the prosthesis and the bone and plays the important role of an ...
Polyethylene was first synthesized by the German chemist Hans von Pechmann, who prepared it by accident in 1898 while investigating diazomethane. [12] [a] [13] [b] When his colleagues Eugen Bamberger and Friedrich Tschirner characterized the white, waxy substance that he had created, they recognized that it contained long −CH 2 − chains and termed it polymethylene.
Wound care with Steri-Strip tape and glue. Wound closure strips are ideal for use in highly contoured areas or areas of musculoskeletal movements, such as joints. They are also for use in areas where swelling, edema, hematomas, or bloating may occur. [citation needed] Additionally, they provide wound support following early suture or staple ...
HDPE is resistant to many different solvents, and is exceptionally challenging to glue; joints are typically made by welding. The physical properties of HDPE can vary depending on the molding process that is used to manufacture a specific sample; to some degree, a determining factor is the international standardized testing methods employed to ...
Adhesive bonding has the advantage of relatively low bonding temperature as well as the absence of electric voltage and current. Based on the fact that the wafers are not in direct contact, this procedure enables the use of different substrates, e.g. silicon, glass, metals and other semiconductor materials.
The adhesive sheet is usually a woven fabric, plastic (PVC, polyethylene or polyurethane), or latex strip. It may or may not be waterproof; if it is airtight, the bandage is an occlusive dressing. The adhesive is commonly an acrylate, including methacrylates and epoxy diacrylates (which are also known as vinyl resins). [2]
The fibrin acts like a glue to seal the injury and builds the fledgling adhesion, said at this point to be "fibrinous." In body cavities such as the peritoneal, pericardial , and synovial cavities , a family of fibrinolytic enzymes may act to limit the extent of the initial fibrinous adhesion, and may even dissolve it.
The glue gun melts the solid adhesive, then allows the liquid to pass through its barrel onto the material, where it solidifies. Thermoplastic glue may have been invented around 1940 by Procter & Gamble as a solution to the problem that water-based adhesives, commonly used in packaging at that time, failed in humid climates, causing packages to ...
