Origin and formation of a chondritic xenolith in Krymka (LL3.2, breccia): Indications for a late formation of the accretionary breccia

Meteoritics &Planetary Science, EarlyView.
Abstract An unusual chondritic xenolith was found in two sequentially prepared thin sections of a sample from the Krymka (LL3.2) chondrite. The xenolith has a rounded, slightly deformed shape of about 5 mm in apparent diameter and is partially surrounded by a double rim made of an inner fine‐grained silicate‐rich rim and an outer sulfide‐rich rim.

Comparative Evaluation of Single and Combined Adsorption and Peroxone Processes for Taste and Odour Control in Reservoir Water

Water and Environment Journal, EarlyView.
ABSTRACT Taste and odour compounds (T&O), particularly 2‐methylisoborneol (2‐MIB) and geosmin, pose persistent challenges in drinking water treatment, as conventional methods often achieve limited removal. This study provides a comparative evaluation of five treatment strategies: activated carbon (AC) adsorption, sulfonic acid‐modified activated carbon

Recovering the properties of aged bitumen using bio-rejuvenators derived from municipal wastes

Ageing of bitumen leads to significant performance deterioration of asphalt pavements and leads to material properties that are not conducive to recycling.

ENABLING PARTIAL UPGRADING IN ALBERTA: A REVIEW OF THE REGULATORY FRAMEWORK AND OPPORTUNITIES FOR IMPROVEMENT

The School of Public Policy Publications, 2019
One of the ways that Alberta can help alleviate its worsening bottleneck in oilexport pipelines is by partially upgrading oil sands bitumen before shipping it to market.

Computational fluid dynamics investigation of bitumen residues in oil sands tailings transport in an industrial horizontal pipe

, 2023
Pipeline transport is commonly used in the oil sand industry to convey crushed oil sand ores and tailings. Bitumen residues in the oil sand tailings can be a threat to the environment that separating them from tailings before disposal is crucial. However,

Use of Hansen Solubility Parameters (HSP) in the selection of highly effective rejuvenators for aged bitumen

While there is considerable research regarding the recycling and reuse of aged bitumen in terms of the evaluation of rheological properties, there is not much fundamental understanding regarding the underlying mechanisms of the rejuvenation process ...

Influence of rejuvenators on bitumen ageing in hot recycled asphalt mixtures

Journal of Traffic and Transportation Engineering (English ed. Online), 2018
The use of reclaimed asphalt pavement (RAP) in new hot mix asphalt (HMA) by means of hot recycling techniques generates the advantage linked to the exploitation of both lytic and bituminous component, consequently leading to the decrease of both virgin ...
