Effect of filler-ash on the properties of epoxy resin composite [PDF]

E3S Web of Conferences, 2023
At present in Russia a huge amount of ash and slag waste from thermal power plants is accumulated in dumps and heaps. For several decades the problem of utilisation of non-combustible residues generated during coal combustion has been studied.

Fe–Mn Heterojunction Modulated Electronic Environment for Enhanced CO2 Capture and In Situ Conversion

Carbon Energy, EarlyView.
Fe–Mn heterojunctions in CaO‐based dual‐functional materials create a built‐in electric field that drives electron transfer. This process generates oxygen vacancies and facilitates CO2 activation, achieving superior conversion. Waste‐derived Fe/Ca oxides enable low‐cost, thermally stable materials, offering a strategy for sustainable carbon capture and

Carbon emission assessment of tunnel infrastructures: From construction to operation

Deep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Uniaxial compressive strength prediction and ratio parameter optimization of titanium tailings composite backfill materials using intelligent hybrid models

Deep Underground Science and Engineering, EarlyView.
Based on the 90 datasets, ERT and four optimization algorithms were used to build four hybrid models to predict the UCS of the backfill body. The SMA‐ERT model was the most effective model, and it can reliably guide the design of the backfill ratio parameters. Abstract This study analyzed the feasibility of using titanium (Ti) tailings as a backfilling
