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 ...

Numerical investigation on ammonia co-firing in a pulverized coal combustion facility: Effect of ammonia co-firing ratio [PDF]

Fuel, 2020
Abstract Recently, the co-firing ammonia (NH3) with coal in boiler has been paid more and more attention. A computational Fluid Dynamics (CFD) simulation approach was built to investigate the NH3 co-firing in a pulverized coal combustion facility with a single swirling burner. The simulation accuracy was evaluated with the experimental data.

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.

Co-Firing of Low- and Middle- Permittivity Dielectric Tapes of Fabricating Low-Temperature Co-Fired Ceramics [PDF]

Korean Journal of Materials Research, 2004
Co‐firing and shrinkage matching of low‐ and middle‐ permittivity dielectric compositions for the application to a low‐temperature co‐fired ceramics system was investigated. Several glass compositions were initially examined for the low‐temperature firing of middle‐ K
