Application of artificial neural network and general machine learning modelling on CO2 adsorption in moisture equilibrated South African high and medium rank coals

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the effect of moisture on CO2 adsorption in South African coals using both experimental and machine learning approaches. Three coal samples (SL, TN, and EM) with varying ranks (RoVmr: 3.49%, 1.26%, and 0.64%, respectively) were collected from different regions of South Africa.

Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.

Influence of Thermal Treatment on the Chemical and Structural Properties of Geopolymer Gels Doped with Nd₂O₃ and Sm₂O₃

Gels
In this research, the influence of the thermal treatment of geopolymer gels at 300 °C, 600 °C and 900 °C when incorporated with 5% rare earth elements (REEs) in the form of (GP-Sm) Sm2O3 and (GP-Nd) Nd2O3 was investigated.

Integrating X‐Ray Computed Tomography and Hydraulic Properties for Soil Quality Assessment Under Soil Compaction

Land Degradation &Development, EarlyView.
ABSTRACT Soil compaction poses a significant threat to soil quality and sustainability, necessitating advanced assessment methods. We hypothesized that incorporating x‐ray computed tomography (XCT)‐derived pore characteristics with hydraulic properties would significantly enhance the development of a soil quality index (SQI) under soil compaction ...

Ternary blend cements concrete. Part II: Transport mechanism

Materiales de Construccion, 2007
With today’s extensive use of cements containing two or more additions (blended cements), predicting concrete durability on the grounds of its strength alone leads to errors that may affect the service life of the resulting structures.

Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

Structural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...
