Poly (ε-caprolactone), (PCL) or simply polycaprolactone as it is usually referred to, is a synthetic biodegradable aliphatic polyester which has attracted considerable attention in recent years, notably in the biomedical areas of controlled-release drug delivery systems, absorbable surgical sutures, nerve guides, and three-dimensional (3-D) scaffolds, for use in tissue engineering. Various poly...

we can recognize ancient environmental, political, economic and cultural conditions with study old textiles. textile objects are important cases for archaeological investigations at the museums. professor mohsen moghadam has collected unique textile collection belonged to parthian, sassanid, early islamic, middle islamic, safavid, qajar and pahlavi periods and a few foreign textiles for example...

Functional graphene-based fibers are promising as new types of flexible building blocks for the construction of wearable architectures and devices. Unique one-dimensional (1D) carbon nanotubes (CNTs) and 2D graphene (CNT/G) hybrid fibers with a large surface area and high electrical conductivity have been achieved by pre-intercalating graphene fibers with Fe3O4 nanoparticles for subsequent CVD ...
