  • The electrospinning technique for the scaffolds designing utilizes the electrostatic force for the production of polymeric fiber ranging from nanoscale to microscale. This process is control by high intensity electric field between two electrodes having electric charges of opposite polarity. One electrode is placed in the polymer solution and other is placed in collector. Generally polymer solution is pumped as result in forming a drop of solution.

  • This paper proposes a novel scaffold cooling for the design of a more conformal and hence more uniform cooling channel. CAD model for constructing the scaffolding structure is examined and cooling performances are validated by computer-aided engineering (CAE) and computer fluid dynamics (CFD) analysis.

  • More than 200 polymers are used for electrospinning like silk fibroin (Zarkoob et al., 2004; Sukigara et al., 2003; Jin et al., 2004), collagen (Mathews et al., 2002), chitosan (Ohkawa et al., 2004), gelatin (Ma et al., 2005) etc. In the field of tissue engineering electrospinning technique is applied for the preparation of nanofiber scaffold design. The process is very versatile in terms of use of polymers, non-invasive and does not require the use of coagulation chemistry or high temperature for fiber generation.

  • Particulate leaching is one of the popular techniques that are widely used to fabricate scaffolds for tissue engineering applications (Ma & Langer, 1999; Lu et al, 2000). Salt, wax or sugars known as porogens are used to create the pores or channels. Here salt is grounded into small particles and those particles that have desired size are poured into a mold and filled with the porogen. A polymer solution is then cast into the salt-filled mold. After the evaporation of the solvent, the salt crystals are leached away using water to form the pores of the scaffold. The process...

  • This is because the extent of damage of the beam members using design solutions at 800 gal 2 at 350 girls, while the beam member by using design solution at 750 gal is not damaged until the seismic force at 800 gal. Since the repair beam member requires scaffolding and other construction works even if the damage is small, repair costs higher than for the column members.

  • A series of RNA-cleaving or DNA-cleaving DNAzymes have been obtained by in vitro selection. However, engineering an allosteric DNAzyme with dual RNA-cleaving and DNA-cleaving activities is very challenging. We used an in vitro-selected pistol-like (PL) DNAzyme as a DNA scaffold for designing a DNAzyme with dual catalytic activities.
