Zero-Emission Cement Plants with Advanced Amine-Based CO Capture.

Decarbonization of the cement sector is essentially required to achieve carbon neutrality to combat climate change. Amine-based CO capture is a leading and practical technology to deeply remove CO from the cement industry, owing to its high retrofittability to existing cement plants and extensive engineering experience in industrial flue gas decarbonization. While research efforts have been made to achieve low-carbon cement with 90% CO removal, a net-zero-emission cement plant that will be required for a carbon neutrality society has not yet been investigated.

NO production of granulocytes associated with antibacterial immune response in Tegillarca granosa.

Nitric oxide (NO) is a signaling molecule and immune effector produced by the nitric oxide synthases (NOS), which involved to various physiological processes of animals. In marine bivalves, hemocytes play important roles in antimicrobial innate immune response. Although hemocyte-derived NO has been detected in several bivalves, the immune function of hemocyte-derived NO is not well understood.

Implicit Task-Driven Probability Discrepancy Measure for Unsupervised Domain Adaptation.

Probability discrepancy measure is a fundamental construct for numerous machine learning models such as weakly supervised learning and generative modeling. However, most measures overlook the fact that the distributions are not the end-product of learning, but are the input of a downstream predictor. Therefore, it is important to warp the probability discrepancy measure towards the end tasks, and towards this goal, we propose a new bi-level optimization based approach so that the two distributions are compared not uniformly against the entire hypothesis space, but only with respect to the optimal predictor for the downstream end task.

Achieving Zero/Negative-Emissions Coal-Fired Power Plants Using Amine-Based Postcombustion CO Capture Technology and Biomass Cocombustion.

The strengthening carbon mitigation efforts to meet the 1.5 °C target requires the development of zero/negative CO emission technologies to eliminate large direct CO emissions from fossil-fuel fired power stations. Amine scrubbing is a dominant technology to capture CO from fossil-fuel power stations, but its application in achieving zero/negative emission in power stations is rarely reported.

Mechanism Investigation of Advanced Metal-Ion-Mediated Amine Regeneration: A Novel Pathway to Reducing CO Reaction Enthalpy in Amine-Based CO Capture.

The high energy consumption of CO and absorbent regeneration is one of the most critical challenges facing commercial application of amine-based postcombustion CO capture. Here, we report a novel approach of metal-ion-mediated amine regeneration (MMAR) to advance the process of amine regeneration. MMAR uses the dual ability of amine to reversibly react with CO and reversibly complex with metal ions to reduce the enthalpy of the CO reaction, thus decrease the overall heat requirement for amine regeneration.

Information Derivation from Vapor-Liquid Equilibria Data: A Simple Shortcut to Evaluate the Energy Performance in an Amine-Based Postcombustion CO Capture.

Evaluation of amine absorbents is crucial for the development of a technically and economically feasible CO capture process. However, the capture performance estimation usually requires a load of experiments, which is time-consuming and labor-intensive. The present study proposed a simple but effective shortcut that employs the fewest experimental data, i.

The recycling of Mn-Zn ferrite wastes through a hydrometallurgical route.

A novel recycling route using acid leaching, reduction, purification, co-precipitation and traditional ceramic process was applied to process the Mn-Zn ferrite wastes and prepare the corresponding high permeability soft magnetic product. Above 95% of Fe, Mn, Zn in the waste materials could be recycled in the form of Mn-Zn ferrite products through the hydrometallurgical route. The comprehensive properties of Mn-Zn ferrite prepared from wastes by this route have broader frequency characteristics, higher resistivity, lower loss coefficient and temperature coefficient as compared to the A102 product (Acme Electronics Corporation, Taiwan).
