Quantitative characterization of aggregates and their chemical constituents in terms of acid and alkaline indicators

open access: yesCase Studies in Construction Materials, 2023
The acidity and alkalinity of aggregates greatly affect the stability, demulsification rate, and road performance of asphalt mixtures. To study the effect of acidity and alkalinity and chemical composition of aggregates, five aggregates, namely limestone

Cell Membrane Composition Affects GPCR Aggregation [PDF]

open access: yesBiophysical Journal, 2014
Recent experimental studies demonstrate that membrane composition is altered in certain human disorders. Modifying membrane composition (e.g. varying the concentration of cholesterol or certain phospholipid species) could in turn affect the behaviour of transmembrane proteins such as G protein-coupled receptors (GPCRs).

Investigating the Effects of Recycled Micropowder and Aggregate on the Properties of Cement Stabilization of Crushed Aggregate (CSCA)

open access: yesAdvances in Materials Science and Engineering, 2022
The recycled powder produced in the process of crushing concrete and brick waste (C&BW) into recycled aggregate will cause environmental pollution. To realize the green full recycling of concrete and brick waste, the cement stabilization of crushed ...

Experimental Evaluation of the Properties of Recycled Aggregate Pavement Brick with a Composite Shaped Phase Change Material

open access: yesMaterials, 2022
Brick waste makes up a significant part of the solid waste that is generated from building demolition globally. The disposal of this waste consumes land, causes environmental pollution, and is a waste of resources. In order to use this construction waste
