Abstract: An acoustic core may include an array of resonant cells configured as a plurality of resonant cell groups. The resonant cell groups may include a plurality of resonant cells configured as a partitioned resonant cell that include a converging resonant cell and a diverging resonant cell. The converging resonant cell and the diverging resonant cell may be defined by a plurality of cell walls integrally formed with one another and a partition integrally formed with the plurality of cell walls. The partition may at least partially delimit the converging resonant cell from the diverging resonant cell. The converging resonant cell may define an upper resonant space delimited by the partition and a top face of the array of resonant cells. The diverging resonant cell may define a lower resonant space delimited by the partition and a bottom face of the array of resonant cells.

Abstract: Syrup produced in a lignocellulosic biomass fermentation process is used as a binder for soil conditioning materials to make an agricultural composition that is easily handled and applied. The syrup binds powdery soil conditioning materials such as lime and gypsum to form pellets or granules.

Abstract: A composition that is useful in land surface applications is produced from ash resulting from burning at least one of lignocellulosic filter cake and lignocellulosic syrup co-products of a lignocellulosic biomass fermentation process for production of ethanol. The composition can be applied to surfaces such as fields, roads, and landfills as a stabilizer and/or fertilizer. Burning of material to produce the ash provides thermal energy.

Abstract: Lignocellulosic syrup is produced as a co-product in a lignocellulosic biomass fermentation process, such as one producing ethanol from lignocellulosic biomass. The lignocellulosic syrup may be used as a binder of particulate materials. In addition, the syrup may be used as an adhesive.
