Abstract: Compositions and methods are provided for the prevention or treatment of RSV infection and SARS-CoV2 virus related infections, such as COVID-19 (2019-nCoV), in a human. The methods include administering one or more doses of a composition comprising an encapsulated nano-metal oxide (NMO) or nano-metal oxide chelate (NMO-Ch). The dose can be formulated for topical or parenteral administration. Topical administration includes administration as a nasal spray, or by inhalation of respirable particles or droplets. Particles or droplets contain material systems that include composite particles having a core and one or more shells that enclose the core. In this case, the shell is a nonlamellar amorphous material, and the internal matrix core contains a metal oxide or metal oxide chelate.

Abstract: After disposable pipette tips are used by an automated pipettor, they are released by the pipettor and fall into a waste container. When the waste container is removed to be emptied, the pipette tips are temporarily sequestered in a pipette tip holding station so that the automated pipettor may operate uninterrupted. After the waste container is replaced, the sequestered pipette tips are released by the holding station into the waste container.

Abstract: A friction disk includes a friction disk core having a first surface with multiple channels extending radially across the first surface. The friction disk may further include a first wear liner having two wear liner segments each configured to be coupled to the first surface of the friction disk core to form an annular liner and each including a wear surface, a non-wear surface, and a rib extending from the non-wear surface and configured to be received by one of the multiple channels.
