Electrospinning

Dosimetry systems developed in standards laboratories utilize calorimetry, ionization and chemical methods for determining absorbed dose to water. One chemical method, the gel dosimeter, in which substances carrying dosimetric information are suspended in a gel matrix, allows dose distributions to be measured in three dimensions (3D), promising true 3D quality assurance measurements in radiotherapy treatment planning. Gel dosimetry has many advantages compared to conventional dosimetry techniques

the fiber surface to enhance vascular endothelial cell (VEC) adhesion and encapsulation of miRNA-126 (miR-126) complexes in the electrospun fibers to accelerate VEC proliferation. The electrospun membranes were specially prepared by emulsion electrospinning

Abstract Conductive polymers have promising applications in the field of tissue engineering as tissue scaffolds. Many tissue types respond favorably to electrical stimulation, because of this conductive polymers can be used for the regeneration of damaged tissue. This review will focus on the synthesis and fabrication of conductive polymers as well as their applications in tissue engineering. Introduction All cells exhibit some form of electrical excitability, from voltage gated ion channels

environment. Another advantage of this machinery is that it is low-cost and eco-friendly. Recycling of spilled oil and regeneration of the Me-CNT sponges is done primarily by heat treatment. After use, the sponges are gathered by magnets, collected and heated (to 493K to release the gasoline vapour or 573 °C to release diesel). After regeneration, the sponge can be reused multiple times for oil sorption. In fact it can be recycled more than 1000 times. [Xuchun Gui, Zhiping Zeng, Magnetic and Highly

Topical Review Use of nano-structured neural scaffolds for neural regeneration in case of Parkinson’s Disease ABSTRACT Parkinson’s Disease (PD) affects a large percentage of people all over the world. Currently, an effective strategy for regeneration of neurons that are lost in PD does not exist; however, nanotechnology has offered new avenues in the field of neural tissue regeneration. Nanostructured scaffolds have been shown to have the ability to promote neuronal growth and their excellent biomimetic

Hai (2011) demonstrated that the highly active carbonaceous nanofibers (CNFs), that are prepared via a template-directed hydrothermal carbonization process, can be used as a versatile scaffold for constructing multifunctional membranes. They fabricated CNF-based composite nanofibers, containing different metallic composits through various chemical routes and analysed their inherit dimension and mechanical properties along with application potentials of these membranes in magnetic actuation and continuous-flow

2.3 Cross-linking by two photon polymerization (2PP) Rapid prototyping approaches [28, 29] (e.g., stereolithography, electrospinning, and 3D fiber deposition modeling) have garnered attention for fabricating materials for tissue engineering and other biomedical applications. However, those techniques have lower resolution and are not effectively used to mimic features of the architecture of the natural cells and/or tissues. Recently, 2PP has been employed to create the 3D materials because it can

Chemically these are copolymers of poly (ethylacrylate, methyl methacrylate and chlorotrimethyl-ammonioethyl methacrylate). Electrospinning generates interconnected, nonwoven 3D porous mats with high porosity and high surface area which can mimic

Master of Science in Mechanical Engineering University of Illinois Chicago, Fall 2014 Statement of Purpose by Samuel Devdas The undergraduate curriculum in Mechanical Engineering at RTM Nagpur University introduced a wide gamut of subjects, both in and outside the field. These courses enabled me to understand the field of Mechanical Engineering on the whole. In my opinion, having just a bachelor degree would not allow me to narrow down my research areas for further doctoral thesis. Thus, my purpose

Develop 3D printable natural and synthetic polymer systems, for biological scaffolds, that are tough enough to produce highly complex parts with small internal features and porosity to allow for microvascular regrowth to attach onto the scaffolds. To obtain a scaffold with suitable mechanical and viscoelastic properties (Young’s modulus 0.35± .11 MPa, Tensile stiffness 8.59±3.5 MPa, Equil. Modulus 13.6±1.5 MPa), it is very important to choose the proper polymeric material and fabrication technique10
