Nifuroxazide is an antimicrobial drug from the nitrofuran group, which is used in the treatment of acute bacterial intestinal infections. Its mechanism of action is based on the reduction of the nitro group in bacterial cells, which produces reactive metabolites that permanently damage enzymes and the genetic material of microorganisms. Enzymes of ...

This study explores the potential of Bigpod Sesbania seed oil as feedstock for production of biodiesel. The extracted oil was transformed to biodiesel via transesterification reaction using potassium hydroxide as catalyst. The process variables methanol-to-oil molar ratio (4:1–8:1), catalyst concentration (0.1–0.5 wt%), reaction time (3...

In this work, I aim to examine the various influences of process parameters on the physical andmechanical properties of extruded polystyrene. Since XPS belongs to the group of thermoplasticpolymers, its properties are significantly affected by thermal treatment, particularly temperatureand pressure. However, in addition to these key factors, this p...

Plastic has become indispensable since its introduction in the late 1800s, valued for its flexibility, durability, and affordability. Global plastic production has grown exponentially, reaching 400.3 million metric tons in 2022, despite a temporary decline in early 2020 due to the Covid-19 pandemic. However, only 9% of all plastics ever produced ha...

Phytoremediation with wild plant species could be an environmentally friendly and economicalsolution. Selected wild plants like mint, oregano, chamomile, nettle, and St. John’s wort, from ruralareas in Bosnia and Herzegovina, were collected, lyophilized, and acid-digested for heavy metalsanalysis. Nickel (Ni), copper (Cu), chromium (Cr), cadm...
