AbstractWe tested 9 disinfectants against Candida auris using the quantitative disk carrier method EPA-MB-35-00: 5 products with hydrogen peroxide or alcohol-based chemistries were effective and 4 quaternary ammonium compound-based products were not. This work supported a FIFRA Section 18 emergency exemption granted by the US Environmental Protection Agency to expand disinfectant guidance for C. auris.

Surface Spread

The global outbreak of SARS-Cov-2 (called Covid-19) has claimed many lives, with currently over 59.95 million confirmed cases of infected persons and over 1.4 million deaths worldwide. Spray aerosols used to disinfect areas, surfaces, and objects are crucial to preventing and protecting people against Covid-19. This paper presents and examines various available and approved materials to formulate spray aerosols for disinfection against Covid-19. The formulations are discussed based on the active ingredient and the possible contact time. The virus can be inactivated. The major groups of spray aerosols discussed include quaternary ammonium-based sprays, hydrogen peroxide-based sprays, alcohol-based sprays, acid-based sprays, sodium-based sprays, and other formulations, some of which are recommended by the US Environmental Protection Agency. Information presented here could benefit governments, policymakers, communities, researchers, health workers, and the general public during this pandemic and beyond.

The benefits of electrified powertrains for light-duty vehicles are well understood, however sufficient published information is not available on the benefits of advanced powertrains on the various types of medium and heavy duty vehicles. Quantifying the benefits of powertrain electrification will help fleet operators understand the advantages or limitations in adopting electrified powertrains in their truck fleets. Trucks vary in size and shape, as they are designed for specific applications. It is necessary to model each kind of truck separately to understand what kind of powertrain architecture will be feasible for their daily operations. This paper examines 11 types of vehicles and 5 powertrain technology choices to quantify the fuel saving potential of each design choice. This study uses the regulatory cycles proposed by the US Environmental Protection Agency (EPA) for measuring fuel consumption.
