The K2CO3-based sorbent is promising for CO2 capture from the flue gas of fossil-fuel-fired power plant. In this work, various support/binder materials were utilized to prepare K2CO3-based sorbent pellets by an extrusion method, and their mechanical strength and CO2 capture performance were...

This article follows the development of early UCG (underground coal gasification) ideas. Historical facts are discussed mainly from the technological perspective and early experiments in UCG are analyzed. Our search for the first successful UCG experiment brings to light a new finding, which was...

In the present study, propagation of a gasification flame through a coal channel is considered. A simplified physical model incorporating all of the main physical factors determining the flame front propagation in a gasification reactor is suggested. It is demonstrated that the flame...

Traditional land subsidence indices primarily describe the characteristics of land subsidence at a given site, but such indicators cannot satisfy the requirements for effective land management. We propose a new index system called the point-line-area-volume (PLAV) index system, designed to...

Airlines commonly experience the problem that the sum of freight forwarders’ orders exceeds the airline's fixed capacity for hot-selling routes, while the orders are usually 50 percent for underutilized routes. Airlines cannot dynamically change flights to address the imbalance, since they...

This paper experimentally and analytically studies pricing decisions in closed-loop supply chains. Experimental results show considerable deviations from theoretical predictions by traditional pricing models. Moreover, social relationships can affect decision results, and double marginalization...

Polystyrene (PS) is a common substrate material for protein adsorption on biosensors and bioassays. By employing a quartz crystal microbalance (QCM) technique, we studied the kinetics and thermodynamics of anti-HBeAg adsorption on this substrate in situ. First, a thin PS film was deposited on...

The member selection problem is an important aspect of the formation of cross-functional teams (CFTs). Selecting suitable members from a set of candidates will facilitate the successful task accomplishment. In the existing studies of member selection, the individual performance concerning a...

When using linguistic approaches to solve decision problems, we need linguistic representation models. The symbolic model, the 2-tuple fuzzy linguistic representation model and the continuous linguistic model are three existing linguistic representation models based on position indexes. Together...

Collaboration satisfaction of new product development (NPD) team is a key factor that affects the performance of team. The evaluation of collaboration satisfaction is a useful work for managers to control the operational process of NPD team so as to promote the performance. This paper...
