Oscillations support short latency co-firing of neurons during human episodic memory formation [PDF]

eLife, 2022
Theta and gamma oscillations in the medial temporal lobe are suggested to play a critical role for human memory formation via establishing synchrony in neural assemblies. Arguably, such synchrony facilitates efficient information transfer between neurons

Limited impact of hydrogen co-firing on prolonging fossil-based power generation under low emissions scenarios [PDF]

Nature Communications
Climate change mitigation generally require rapid decarbonization in the power sector, including phase-out of fossil fuel-fired generators. Given recent technological developments, co-firing of hydrogen or ammonia, could help decarbonize fossil-based ...

Simulation study on coal and ammonia co-firing in a tangential firing boiler under different ammonia injection methods [PDF]

Scientific Reports
As a new zero-carbon fuel, ammonia co-firing in coal-fired boilers is one of the feasible technologies for reducing carbon emission. This study validated an ammonia-coal co-firing simulation model using experimental data from a 300 MW unit tangential ...

Effect of combustion temperature on the unburnt carbon during ammonia co-firing with coal combustion [PDF]

Scientific Reports
Ammonia co-firing with coal seems to be the preferred approach to reduce unburnt carbon in existing pulverized coal-fired power plants. However, some operational conditions such as combustion temperature need to be carefully considered.

Studies of ignition behaviour of biomass particles in a down-fire reactor for improving co-firing performance [PDF]

, 2016
To realize large percentage biomass co-firing with coal in existing coal-fired boilers, the combustion behaviour of biomass is expected to be similar or comparable to that of coal. When co-firing with coal, biomass is not necessarily to be ground as fine
