EXERGY-BASED INVESTIGATION OF A COAL-FIRED ALLAM CYCLE [PDF]

E3S Web of Conferences, 2019
Allam cycle is a novel cycle that capitalizes on the unique thermodynamic properties of supercritical CO2 and the advantages of oxy-combustion for power generation. It is a high-pressure supercritical carbon dioxide cycle designed to combust fossil fuels such as natural gas or syngas (from coal gasification systems) with complete CO2 separation at a ...

Effect of staining techniques and repeated firing cycles on translucency, color and biaxial flexural strength of advanced lithium disilicate containing Virgilite crystals

BMC Oral Health
Background The repeated firings can enhance shade matching, translucency, and strength; however, they may also lead to color shifts. Previous research suggests that multiple firings enhance these properties to a certain extent; however, the impact of ...

Assessment of the most adequate pre-treatments and woody biomass sources intended for direct co-firing in the U.S. [PDF]

BioResources, 2012
There is increasing interest in replacing coal with woody biomass in co-firing plants for electrical power. A variety of pre-treatments can be used to make biomass more suitable for co-firing.

A unified framework to model synaptic dynamics during the sleep-wake cycle.

PLoS Biology
Understanding synaptic dynamics during the sleep-wake cycle in the cortex is crucial yet remains controversial. The synaptic homeostasis hypothesis (SHY) suggests synaptic depression during non-rapid eye movement (NREM) sleep, while other studies report ...
