Exploration of the CU-MN-AS ternary phase diagram and MN3B4 antiferromagnets
… more than fifty years ago, both in a tetragonal phase (t-CuMnAs) and orthorhombic phase (o-CuMnAs). Today, the prospect of spintronics has created a new focus on antiferromagnetic materials with Néel temperatures above room temperature, with the goal of reading and writing spin orientations by …

Co-crystal screening of poorly water-soluble active pharmaceutical ingredients. Application of hot stage microscopy on curcumin-nicotinamide system and construction of ternary phase diagram of fenbufen-nicotinamide-water co-crystal system.
… and PXRD, and all confirmed a new crystal phase could have been formed between curcumin and a co-crystallizing agent, nicotinamide. We report that re-crystallization step essentially aids the purification of commercial curcumin, a herbal based actives. Otherwise the prevalence of a new …

A universal approach to stabilize water-oil interface via surfactant self-assembly
… technique (dissipative particle dynamics), the ternary phase diagram for the same material system (involving water, surfactant, and polar oil) that was used in liquid-in-liquid 3D printing is established to study the equilibrium phase behavior. The ternary phase diagram obtained from the …

Materials and coatings derived from the polymerizable ionic liquid surfactant 1-(2-Acryloyloxyundecyl)-3-methylimidazolium bromide
… bromide (IL-Br) was synthesized. The ternary phase diagram of the ILBr/ MMA/water system was constructed at 25 and 60 °C. Several microemulsion polymerizations were carried out, yielding materials that ranged from latexes, which formed transparent films upon drying, to solid rods. …

Development of in situ synthesis of silver polysulfone membrane for water separation
… thermodynamic stability was evaluated via ternary phase diagram. The membrane was characterized in term of morphology, existence of element, surface roughness, porosity and hydrophilicity. Then, the membrane performance was evaluated in respect to water permeability, water quality …

A study of alloys based on the magnesium-lithium system
… an attempt has been made to determine the phase equilibria that occur under near-equilibrium conditions for the case of Mg rich alloys. This has involved the application of optical metallography, x-ray diffraction and differential scanning calorimetry. As a result, the ternary phase diagram …

Use of diffusion multiples to explore the Co-Cr-Fe-Mn-Ni high entropy system, The
… After creation of these multiples, the ternary and quinary interface regions were examined using scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), and nanoindentation. The Cr/NiCo region experienced interdiffusion but no …

Irradiated recycled plastic as a concrete additive for improved chemo-mechanical properties in hardened cement pastes
… that various differences in C-S-H and C-A-S-H phase formation from the addition of both irradiated plastic and mineral additives helped to form high-density phases that contributed to higher relative strengths. BSE analysis showed that an increased alumina content among fly ash samples helped …

Reduction and softening/melting behaviour of olivine pellet in the experimental blast furnace
… but also initial melt formation containing FeO phase. The chemical composition of slag phases of excavated pellet samples were located on the line between 2FeO·SiO2 and 2MgO·SiO2 in the FeO-MgO-SiO2 ternary phase diagram. This result is in good agreement with the assumption that the initial slag …

Intermetallic phases formed during galfanizing
… to produce a coating which has no intermetallic phases in the coating but this condition is not always achieved. Though it is important, the nature of the intermetallic phases and the mechanisms of their formation and growth during Galfanizing are far from fully understood. The overall objective …

Structure Formation Mechanism of Isoporous Block copolymer Membranes
This thesis deals with the microphase separation of poly(styrene-b-vinylpyridine) block copolymers in highly concentrated solutions induced by evaporation of a binary solvent mixture of a high and low boiling solvent. During self-assembly and non-solvent induced phase separation by immersion in …
