Look around any modern device—your phone, laptop, car, airplane, or even medical equipment—and you’ll find something invisible doing an enormous amount of work: adhesion. Tiny layers of glue, tape, bonding agents, and molecular forces quietly hold together the systems we depend on every day.

In this episode, we explore the engineering behind “sticky technology.” We dive into materials science, polymer chemistry, nanotechnology, mechanical engineering, surface science, manufacturing engineering, and industrial design. We examine how adhesives work at a molecular level, how surfaces bond through chemical and physical interactions, and why modern engineering increasingly relies on glues instead of screws, bolts, or welds.

We also explore pressure-sensitive adhesives, epoxy resins, structural bonding in aerospace, medical-grade adhesives  ...
