European Journal of Inorganic Chemistry, Volume 27, Issue 36, December 20, 2024.Aqueous synthesis of ZIF‐8 MOF has been optimized and characterized. The material was then tested for acid environment response and loaded with a wide spectrum antibacterial molecule (sulfathiazole) used for SARA treatment in cows. The loaded material was tested for drug release at different pH, evidencing strong dependence in release time.

Experimental methods in chemical engineering: X‐ray fluorescence—XRF
The Canadian Journal of Chemical Engineering, Volume 102, Issue 6, Page 2004-2018, June 2024.Abstract X‐ray fluorescence (XRF) is a non‐destructive spectrometric technique to detect elements with an atomic number from 11 (sodium) and beyond 92 (uranium). When X‐rays or gamma rays eject tightly bound inner core electrons, an electron from an outer shell will fill the empty orbital and fluoresce.

The Roasting of Copper Anode Slimes in the Nichols‐Herreshoff Furnace
Transactions of The Electrochemical Society, 1932 Operating experiences with the new Nichols‐Herreshoff roaster are recorded. The roaster is installed at Laurel Hill, N. Y., El Paso, Texas, and Montreal East, Quebec. Slimes containing 25 to 50 per cent H2O are fed directly into the roaster. The maximum temperature range is 300 to 350° C. The capacity is 2,700 kg. per 24 hr.
