New mechanisms to control dental procedure spray emissions

Alexandria, Va., USA — Since the onset of COVID-19 the potential risk of dental procedure spray emissions for SARS-CoV-2 transmission has challenged care providers and policy makers alike. The study, “Mechanisms of atomization from rotary dental instruments and its mitigation,” published in the Journal of Dental Research (JDR), found that there are multiple mechanisms for […]

New procedure will reduce the need for rare metals in chemical synthesis

Tertiary alkylative cross-coupling of alkyl or aryl electrophiles. Credit: Kanazawa University Pharmaceuticals, plastics, and many other chemical products have transformed human life. To prepare these products, chemists often use a catalyst—frequently based on rare metals—at various points in their syntheses. Although rare-metal catalysts are incredibly useful, their limited supply means that their use is unsustainable […]
