[]-Face π-expanded coumarins are synthesized by employing the Scholl cyclization method. These new arene-annulated dipolar coumarins display interesting absorption and fluorescent properties. The large Stokes shifts, tuneable fluorescent quantum yields, and high photostability reveal promise in bioimaging application.

With the growing demand for nickel in the stainless steel and battery industries, conventional methods of extracting nickel from ores face challenges such as high production costs and environmental concerns. This study proposes a new process for the recovery of nickel metal and the production of nickel-iron alloys from nickel-bearing scrap. The reduction rates of nickel and iron oxides were investigated by optimizing the roasting temperature, time, and C/O ratio, and the process was optimized using response surface methodology (RSM).

Trigeminal neuralgia is the most common cause of facial pain in individuals over 50 years old and can have a profoundly negative impact on quality of life. Epidemiological studies have measured the annual incidence of trigeminal neuralgia at around 4-5 cases per 100,000 inhabitants per year. In Iceland, this would amount to about 16-20 new cases annually.
