Nano-Engineered Structural Joints: Materials, Procedures and Applications Thereof

A method of joining two articles through a nano-enhanced joining medium is described. Nanomaterials are applied to the surfaces of sheets made of the joining medium via casting or spraying. Said sheets with nanomaterial coatings are then placed between the joining surfaces of the articles, and then application of pressure and heating is used to form a nano-engineered structural joint at the interface of said articles. The distinctly high specific surface area of nanomaterials and the energetic preference of their functionalized surfaces for bonding facilitate the joining process. Nano-engineered structural joints complement high strength levels with desired toughness and the compliance needed for accommodating deformation (e.g. thermal expansion) mismatches of joined articles without generating high stress levels near their interface. The limited quantity (per unit joint surface area) of nanomaterials utilized in nano-engineered joints benefits their economic viability.

Layered polymer film and its manufacturing process for medical bags with multiple chambers

본 발명은 다층 폴리머 필름 및 다중챔버가 있는 백에 대한 것으로서 챔버는 바깥쪽 경계지대의 시임과 하나이상의 챔버분리지대의 시임에 의해 형성되며, 시임은 챔버를 대면하는 폴리머 재료로 형성된다. The present invention is directed to a bag with a multi-layer polymer film and a multichamber wherein the chamber is formed by a seam of the outer boundary zone and a seam of one or more chamber separation zones, the seam being formed of a polymeric material facing the chamber. 챔버를 대면하는 폴리머 재료는 바깥쪽 경계지대에서는 분리될 수 없게 밀봉되며 챔버분리지대에서는 시임이 5N-20N 의 힘으로 분리될 수 있게 밀봉된다. 밀봉공정으로부터 다른 결합강도가 밀봉온도를 변화시킴으로써 얻어진다. The polymeric material facing the chamber is inseparably sealed at the outer boundary and the seam at the chamber separation is sealed so that it can be separated by a force of 5N-20N. Different bonding strengths are obtained from the sealing process by changing the sealing temperature.
