in this study the performance of clay nano-particles on the soil reinforced with polypropylene fibers (pp-fiber) has been investigated. also a series of investigations concerning the effect of random orientation of fibers on the engineering behaviour of soil were conducted. soil mixtures were modified with varying percentages of nanoclay and fibers. unconfined compressive strength (ucs), compac...

BACKGROUND The microstructural organization (collagen fiber alignment) of the posterior cruciate ligament (PCL), which likely corresponds with its functional properties, has only been described qualitatively in the literature, to our knowledge. The goal of this study was to quantify the tensile mechanical and microstructural properties of the PCL and compare these qualities between the anterola...

An optical fiber with nano-electromechanical functionality is presented. The fiber exhibits a suspended dual-core structure that allows for control of the optical properties via nanometer-range mechanical movements. We investigate electrostatic actuation achieved by applying a voltage to specially designed electrodes integrated in the cladding. Numerical and analytical calculations are preforme...

While melt electrowriting (MEW) can result in complex microstructures, research demonstrating such fabrication with active materials is limited. Herein, magnetoresponsive poly(?-caprolactone) (PCL) inks containing up to 10 wt% of iron-oxide (Fe3O4) nanoparticles are used produce fiber diameters 9.2 ± 0.6 µm ordered microstructures when processed by MEW. Introducing the Fe3O4 has a minimal overa...

FMLs are considered by many industries, including the aerospace industry, due to their important advantages such as high strength, low weight, corrosion and moisture resistance, good fatigue properties, and so on. The purpose of the present study is to improve the mechanical properties of the panel through the addition of nanoscale by improving the structure of the FML. For this purpose, the pe...

The study investigates the effect of polycaprolactone (PCL) concentration on metformin hydrochloride (MH) release ratio electrospun nanofiber scaffolds. Blend and emulsion electrospinning are used to produce performance nanofibrous scaffolds was evaluated by morphology (Field Emission Scanning Electron Microscopy, FESEM), chemical (Fourier Transform Infrared Spectroscopy, FTIR), thermal (Differ...

Poly(3-hydroxybutyrate) (PHB) has been proposed to be a potential candidate used as biomaterial. However, its poor processability, high brittleness and rigidity have limited applicability. Transesterification reactions with poly(e-caprolactone) (PCL), one of the most promising biomedical materials, emerge an attractive alternative improve mechanical properties. In this work, poly(3-hydroxybutyr...

Material composition and topography of the cell-contacting material interface are important considerations in the design of biomaterials at the nano and micro scales. This study is one of the first to have assessed the osteoblastic response to micropatterned polymer-ceramic composite surfaces. In particular, the effect of topographic variations of composite poly(ε-caprolactone)/hydroxyapatite (...

Identification of the key components in the physical and chemical milieu directing donor cells into a desired phenotype is a requirement in the investigation of bioscaffolds for the advancement of cell-based therapies for retinal neurodegeneration. We explore the effect of electrospun poly-ε-caprolactone (PCL) fiber scaffold topography and functionalization and culture medium, on the behavior o...
