Chemical looping combustion (CLC) is one of the most advanced technologies allowing for reduction in CO2 emissions during solid fuels. The modified method combines chemical with oxygen uncoupling (CLOU) and situ gasification (iG-CLC). As a result, an innovative hybrid came into existence, making above two complementary. Since complexity CLC still not sufficiently recognized, study this process ...

Enhancers are closely positioned with actively transcribed target genes by chromatin looping. Non-coding RNAs are often transcribed on active enhancers, referred to as eRNAs (enhancer RNAs). To explore the kinetics of enhancer-promoter looping and eRNA transcription during transcriptional activation, we induced the β-globin locus by chemical treatment and analysed cross-linking frequency betwee...

Studies of coal surface interactions are important for Understanding how technologically important reagents interact with Coal. Thermodynamic data provide a quantitative means to assess the interactions between reagents and coal. Knowledge of interaction strengths for solutes with coal surfaces should enable the design of more effective coal reaction strategies and lead to better utilization of...

The correlation between local mechanical (elasto-plastic) and structural (composition) properties of coal presents significant fundamental and practical interest for coal processing and for the development of rheological models of coal to coke transformations. Here, we explore the relationship between the local structural, chemical composition, and mechanical properties of coal using a combinat...

zeolite was synthesized from coal tailings and coal fly ash sampled from zarand coal washing plant, iran, using h2o2–promoted hydrothermal treatment. samples consisted mainly of sio2 and al2o3 which are the main components for the zeolite synthesis. to perform the experiments, appropriate amount of the starting materials were mixed with 240 ml volume of 30% h2o2 at room temperature with continu...

One of the most important methods to produce sponge iron is coal based reduction of iron ore. Direct reduction methods based on coal are being improved due to the abundance of coal sources and its lower cost in comparison with natural gas. Volatile materials in coal play an important role in the reduction of iron oxides. In this study, noncoking coal with high volatile materials from Iran and c...
