Reusing coal ash of thermal power plant in a pavement base course

Journal of King Saud University: Engineering Sciences, 2021
Nowadays, the disposing of coal bottom ash from thermal power plants is increasing day by day and creates serious environmental problems, especially in Vietnam. The utilization of coal ash from Vietnam’s thermal power plants in a pavement base course has

Hydrological and Geochemical Properties of Bottom Ash Landfills

Environmental Earth Sciences, 2023
Abstract In Switzerland, municipal solid waste incineration (MSWI) bottom ash is deposited in open landfills, which leads to its interaction with rainwater and thus the formation of a polluted leachate. After completion, the landfill enters the aftercare phase, during which leachate contamination is expected to decrease to such level, that no ...

Enhanced Formation of Dicarboxylic Acids in the Catalytic Oxidation of Polyethylene With O2 and NOx

Angewandte Chemie, EarlyView.
The oxidation of polyethylene in the presence of a mixture of O2 and NOx and with Cu2+/V5+ as catalyst yields ∼51 mol% diacids, while retaining ∼80 mol% of the carbon in the oil fraction. The developed method is robust and tolerates several polymer types as well as impurities.

Influence of the Mass Percentage of Bottom Ash and Its State of Maturation on the Mechanical Performance of a Bio-Composite

Buildings
This study examines the influence of the mass percentage and maturation stage of bottom ash on bio-composite mechanical strength. Two kinds of bottom ash were used: matured and non-matured.

Design Experiment for Leveraging Material Value Coal Ash as Material Mixture of Paving Block

MATEC Web of Conferences, 2018
The coal-fired thermal power plant is the main source of coal ash production. Coal ash collected at the bottom of the furnace (boiler) is called coal bottom ash (CBA) and fly ash remaining combustion called coal fly ash (CFA).

Interface Effects in Ultrathin Silicon on Insulator Films

Advanced Functional Materials, EarlyView.
This work establishes a systematic framework to discriminate how bulk and interface phenomena affect charge transport in ultrathin P‐doped silicon‐on‐insulator (SOI) films. For Si films below 15 nm, electrical characterization demonstrates that interface states drive charge transport, shifting the metal‐insulator transition (MIT) critical dopant ...

Interstitium‐Mimicking Porous Alveolar Membranes Enable Physiologic Aerosol Transport and Distinct Acute‐Chronic Lung Injury Responses

Advanced Functional Materials, EarlyView.
An interstitium‐mimicking membrane combines three‐dimensional alveolar geometry, high pore interconnectivity, and mechanical compliance to overcome transport limitations of conventional lung‐on‐chip barriers. The resulting platform supports physiologic aerosol transport, quantitative analysis of cross‐barrier particle movement, and reveals divergent ...

Applicability of coal bottom ash for the rehabilitation of clay mines: Potential as a backfill material

, 2023
The higher cost associated with the restoration of clay mines and shortage of suitable filling materials have created many abandoned clay mines in Sri Lanka, which leads to many environmental and health issues.

Second‐Harmonic Hyper‐Mie Optical Activity Enables Closed‐Loop Chiral Photochemistry

Advanced Materials, EarlyView.
Nonlinear chiral photochemistry is demonstrated in CdTe/CdO nanohelices, where circularly polarized infrared light both drives and tracks photo‐oxidation via second‐harmonic scattering. This closed‐loop process reveals real‐time structural evolution, including shell fracturing and core exposure, accompanied by a transition from hyper‐Mie to hyper ...
