INTERDEPENDENCE BETWEEN POINT LOAD INDEX, COMPRESSIVE STRENGTH AND CRUSHING RESISTANCE OF JORDAN OIL SHALE AND RELATION TO CALORIFIC VALUE; pp. 252–268 [PDF]

Oil Shale, 2015
Rock parameters are important to be considered in mine design. Physical-mechanical tests were carried out on oil shale and dolostone samples from the Attarat Um Ghudran oil shale area in central Jordan, in order to determine the rock mass properties.

Scaled water sigma potential as a descriptor of LCST and UCST behavior in aqueous ionic liquid solutions

Journal of Ionic Liquids
This study introduces the scaled sigma potential of water (σr), a new metric using the COSMO-RS (Conductor like Screening Model for Real Solvents) framework, as a descriptor of upper and lower critical solution temperature (UCST and LCST) governed phase ...

Tuning the Size of Thermoresponsive Poly(N-Isopropyl Acrylamide) Grafted Silica Microgels

Gels, 2017
Core-shell microgels were synthesized via a free radical emulsion polymerization of thermoresponsive poly-(N-isopropyl acrylamide), pNipam, on the surface of silica nanoparticles. Pure pNipam microgels have a lower critical solution temperature (LCST) of

Synthesis and Thermo-Responsive Performance of Chitosan-Based UCST-Type Superplasticizers for Cement Composites

Polysaccharides
Conventional polycarboxylate superplasticizers (PCEs) suffer from uncontrollable adsorption, characterized by rapid initial uptake and limited subsequent release, which causes pronounced slump loss, particularly at elevated temperatures where hydration ...

Thermodynamic Limits to Molecular Doping in Conjugated Polymers: A Perspective on Phase Behavior and Miscibility

Advanced Materials, EarlyView.
Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.
