Coupling hydrothermal liquefaction and aqueous phase reforming for integrated production of biocrude and renewable H2

AIChE Journal, Volume 69, Issue 1, January 2023., 2023
Abstract Lignin‐rich stream from lignocellulosic ethanol production was converted into biocrude by continuous hydrothermal liquefaction (HTL) while hydrogen was produced by aqueous phase reforming (APR) of the HTL aqueous by‐product. The effects of Na2CO3 and NaOH were investigated both in terms of processability of the feedstock as well as yield and ...

Birth defects associated with paternal firefighting in the National Birth Defects Prevention Study

American Journal of Industrial Medicine, Volume 66, Issue 1, Page 30-40, January 2023., 2023
Abstract Background Few studies have evaluated birth defects among children of firefighters. We investigated associations between birth defects and paternal work as a firefighter compared to work in non‐firefighting and police officer occupations. Methods We analyzed 1997–2011 data from the multi‐site case‐control National Birth Defects Prevention ...
