Formulation, characterization and evaluation of minocycline hydrochloride loaded polyurethane/collagen nanofibers via electrospinning as wound dressings.

Objective: It was aimed to formulate minocyline. HCI loaded electrospun polyurethane/collagen (PU/Col) and polyurethane/collagen/polycaprolactone (PU/Col/PCL) nanofibers are intended for use as a wound dressing.

Methods: The effect of polymer ratio and addition of PCL on the morphology, diameter, drug delivery, encapsulation efficiency, mechanical properties, antibacterial activity against and , cytotoxicity, cell adhesion and proliferation were investigated.

Investigation of Trace Elements in Vegan Foods by ICP-MS After Microwave Digestion.

Veganism is gaining popularity around the world day by day. Vegan nutrition is a diet in which not all animal foods are used. A vegan diet does not contain meat, fish, milk and dairy products, and eggs and consists of vegetables, fruits, grains, legumes, and nuts.

Valorization of spent coffee grounds recycling as a potential alternative fuel resource in Turkey: An experimental study.

Unlabelled: In this study, recycling of spent coffee grounds (SCG) as a potential feedstock for alternative fuel production and compounds of added value in Turkey was assessed. The average oil content was found (≈ 13% w/w). All samples (before and after extraction) were tested for scanning electron microscopy (SEM), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), X-ray diffraction (XRD), calorific value, surface analysis and porosity, Fourier transform infrared (FT-IR), and elemental analysis to assess their potential towards fuel properties.
