Metals foams for biomedical applications: Processing and mechanical properties
Optimized structures found in nature can be sometimes imitated in engineering structures. The recent interest in functionally graded metallic materials makes bone structures interesting because bones are naturally functionally ...
Swarm and entropic modeling for landmine detection robots
Even at the dawn of the 21st century, landmines still pose a global threat. Buried just inches below the surface, combatants and noncombatants alike are all at risk of stepping on a mine. Their very nature is such that ...
Controlled release of drugs from tablet coatings
Controlled - release technology for drug delivery applications is designed to target the drug to particular places or cells in the body, to overcome certain tissue and cellular barriers, and to control the duration and ...
Organotin compounds as PVC stabilizers
When poly(vinyl chloride) is fabricated, it passes between rollers (calendars) at about 200 ◦C, which causes elimination of some HCl at allylic defects in the polymer, as shown below (Figure 3.3.1). Furthermore, the released ...
