Background: The oxygen isotopes O-17 and O-18 are extremely useful for tracing molecular processes in chemistry, agrochemistry, biology and pharmacy. The isotopes O-17 or O-18 are used to replace the common O-16 in a compound of interest. The O-17 and O-18 labelled compound can be traced by mass spectroscopy because O-17 and O-18 are both heavier than O-16. The O-17 compound can also be traced by NMR (nuclear magnetic resonance) spectroscopy as O-17 has a nuclear spin. Using oxygen isotopes, a pharmacist can label a drug and monitor its activity in a cell.

Plastic gears offer economic advantages, i.e design flexibility, reduced noise, ability to operate without lubrication and corrosion-resistance. Etc. In some cases they can be a better choice than metal gears. The research group on gear technology of a Swiss university of applied sciences carries out research, product and process development in the area of transmission systems and gearwheels made from steel and plastic in order to test the limitations of plastic gears relative to metal gears and improve quality, process productivity, and sustainability.

A Swiss company is looking for a board manufacturer - or a research & development partner - that produces - or develops - an open-pore, air-permeable, non-flammable or flame retardant, lightweight board. The board size is approximately 3.0 m x 1.2 m. The semi-finished product can be delivered from anywhere in the world and will be finished, processed and distributed by the Swiss company.

Diabetes mellitus is one of the major health concerns worldwide affecting 425 million people and its prevalence is expected to increase to 629 million in 2045. It is estimated that 12% of the global health expenditure is spent on diabetes (around $727 billion). One serious complication of diabetes mellitus is the diabetic foot ulcer (DFU). Impaired local blood circulation and the resulting low tissue oxygenation, nutrient supply and waste elimination is a major cause for compromised wound healing in diabetic patients and wounds often become chronic and non-healing.
