Polyethylene oxide –b– polypropylene oxide -bpolyethylene oxide (EO106PO70EO106) block copolymer self-organizes into polymeric supramolecules, characterized by NMR as phase transition from the isotropic stack-up block structure to the ordered cubic polymeric supramolecular structure. Its dependence on both temperature and copolymer concentration is clearly shown by the changes in line shape and...

Newly synthesized Polypropylene-g-Polyethylene glycol polymer was first time used for a compartment-less enzymatic fuel cell. Working electrodes based on Polypropylene-g-Polyethylene glycol were operated as unmediated and mediated system (with ferrocene and gold/cobalt oxide nanoparticles). Glucose oxidase and bilirubin oxidase was selected as anodic and cathodic enzyme, respectively. Glucose w...

Hypothesis / aims of study The use of polypropylene mesh to repair urinary incontinence and vaginal prolapse has decreased the recurrence of these conditions. However, it has also been related to specific complications such as vaginal erosions (1). Nitric oxide (NO) can modulate angiogenesis, vasodilation and fibroblastic reaction (2). We studied the effect of a NO donor (S-nitrosoglutathione G...

Polypropylene has been widely used as dielectric material in organic thin-film capacitors due to their high breakdown strength, low loss and self-healing capability. However, polypropylene’s energy density is relatively low. Increasing the of polypropylene by adding materials with a constant commonly used. Still, it often leads an increase loss, lower strength other shortcomings. In this study,...

3-Hydroxy-2-naphthoic acid hydrazide (HNH), a new reductant and modifier, was applied to reduce and modify graphene oxide (GO) in a one-step process. The obtained HNH reduced graphene oxide (HNH-rGO) was characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), Raman spectroscopy, X-ray photoelectron spectroscopic (XPS) and Fourier transform infrared spectra (FTIR). The resu...

BACKGROUND AND AIM Prosthetic mesh repair for abdominal wall hernias is widely used because of its technical simplicity and low hernia recurrence rates. The most commonly used material is pure polypropylene mesh, although newer composite materials are recommended by some centers due to their advantages.However, these meshes are more expensive than pure polypropylene meshes. Resterilization of a...
