TL;DR: In this paper, the authors used transition metals (Cu, Co, Fe, Ni) to find potential oxygen carrier candidates that had less interaction between the active-sites and supports, which could help increasing the selectivity of CO 2 among other gases (CO, H 2 ) and to reduce the solid inventories in the CLC reactor system.

TL;DR: In this paper, a two-phase solid-fluid flow is simulated to predict pressure losses and cuttings concentration in eccentric horizontal annuli as a function of varying drilling parameters: fluid velocity, diameter ratio, inner pipe rotation speed, and fluid type.
Abstract: In oil and gas drilling operations, predictions of pressure losses and cuttings concentration in the annulus are very complex due to the combination of interacting drilling parameters. Past studies have proposed many empirical correlations to estimate pressure losses and cuttings concentration. However, these developed correlations are limited to their experimental data range and setup, and hence, they cannot be applicable to all cases. CFD methods have the advantages of handling complex multiphase flow problems, as well as, an unlimited number of physical and operational conditions. The present study employs the inhomogeneous (Eulerian-Eulerian) model to simulate a two-phase solid-fluid flow and predict pressure losses and cuttings concentration in eccentric horizontal annuli as a function of varying drilling parameters: fluid velocity, diameter ratio (ratio of inner pipe diameter to outer pipe diameter), inner pipe rotation speed, and fluid type. Experimental data for pressure losses and cuttings concentration from previous literature compared very well with simulation data, confirming the validity of the current model. The study shows how reliable CFD methods can replicate the actual, yet complex oil and gas drilling operations.

TL;DR: In this article, a review of the literatures associated with the adoption of different novel techniques in Construction Waste Management and Policy (CWMP) to find out the state and development of the construction waste stream and to reveal gaps for further investigations through the exploration of several publications which have emphasis on construction waste management.
Abstract: The purpose of this study is to review extensively the literatures associated with the adoption of different novel techniques in Construction Waste Management and Policy (CWMP) to find out the state and development of the construction waste stream and to reveal gaps for further investigations through the exploration of several publications which have emphasis on construction waste management. A cross-referencing examination was performed to ensure the comprehensiveness of the study. All references cited by the selected papers were searched manually, and then the titles of potentially related articles were aggregated into an Excel table to avoid replication. Following a systematic evaluation of the retrieved papers, two characteristic classification criteria of the current literatures were revealed as waste management and waste regulatory or policy. The findings show that there is a substantial growth in the number of studies associated with construction waste which attempts to reveal comprehensive results in the adoption of numerous methods from various perspectives. Nevertheless, there are several areas which need further research in both theoretical and intensive approaches in the empirical aspect to experiment the real application of the proposed methods. This study shows that reuse and recycle rates of construction waste is still minimal which continue to impact the environmental well-being. This review presents future direction and research gaps as well as recommendations on CWMP adoption which will be helpful to academics and professionals that are working or intend to operate in the related area.
