Optimizing large-scale CO pipeline networks using a geospatial splitting approach.

CO transport infrastructure is the backbone of carbon capture and storage (CCS) technology for the mitigation of carbon emissions and project deployment viability. In conventional large-scale CO pipeline network designs, the storage sites are generally assumed as the centroids of the major geologic basins, however, this approach might provide suboptimal solutions since the large extension of some storage formations significantly increases the length of the CO transportation networks. To address this situation and obtain optimal pipeline routes, we present a novel geospatial splitting framework that partitions large basins into multiple sub-sinks.

Two-Dimensional Ultrathin FeSn Kagome Metal with Defect-Dependent Magnetic Property.

Two-dimensional (2D) FeSn, which is a room-temperature ferromagnetic kagome metal, has potential applications in spintronic devices. However, the systematic synthesis and magnetic study of 2D FeSn single crystals have rarely been reported. Here we have synthesized 2D hexagonal and triangular FeSn nanosheets by controlling the amount of FeCl precursors in the chemical vapor deposition (CVD) method.

Sustainable energy solutions: Well retrofit analysis and emission reduction for a net-zero future in the Intermountain West, United States of America.

To achieve net-zero emissions by 2050, we need economic means of sequestering carbon dioxide (CO) and reducing greenhouse gas emissions (GHG). We analyze the sequestration potential of the Intermountain West (I-West) region, US, as a primary energy transition hub through analysis of wellbore retrofit potential and emission reduction in both fugitive gas abatement and flare gas. We selected the I-West region due to its abundant energy sources and oil and gas production legacy.

Modeling Ecological Constraints on a CO Pipeline Network.

Carbon capture, utilization, and storage (CCUS) are a critical set of strategies to decarbonize the industrial and power sectors and to mitigate global climate change. Pipeline infrastructure connecting CO sources and sinks, if not planned strategically, can cause environmental and social impacts by disturbing local landscapes. We investigated the impacts of these considerations on optimal CO pipeline routing and sink locations by modifying and leveraging an open-source CCUS infrastructure model, We expanded from a cost-minimizing to a multiobjective framework, explicitly incorporating environmental protection objectives.

Phase-based design of CO capture, transport, and storage infrastructure via SimCCS.

The design of optimal infrastructure is essential for the deployment of commercial and large-scale carbon capture and storage (CCS) technology. During the design process, it is important to consider CO capture and storage locations and CO transportation pipelines to minimize the total project cost. SimCCS, first introduced in 2009, is an integrated open-source tool to optimize CCS infrastructure.

Improving deep learning performance for predicting large-scale geological [Formula: see text] sequestration modeling through feature coarsening.

Physics-based reservoir simulation for fluid flow in porous media is a numerical simulation method to predict the temporal-spatial patterns of state variables (e.g. pressure p) in porous media, and usually requires prohibitively high computational expense due to its non-linearity and the large number of degrees of freedom (DoF).

Impact of adjustment measures on reducing outpatient waiting time in a community hospital: application of a computer simulation.

Background: As an important determinant of patient satisfaction, waiting time, has gained increasing attention in the field of health care services. The present study aimed to illustrate the distribution characteristics of waiting time in a community hospital and explore the impact of potential measures to reduce outpatient waiting time based on a computer simulation approach.

Methods: During a one-month study period in 2006, a cross-sectional study was conducted in a community hospital located in Shanghai, China.
