Damage to the water resources and environment as a consequence of oil production and use of fossil fuels, has increased the need for applying various technologies and developing effective materials to remove contaminates from oily wastewaters resources. One of the challenges for an economic indu...

Detection of radiological iodine gas after nuclear accidents or in nuclear fuel reprocessing is necessary for the safety of human life and the environment. The development of sensors for the detection of iodine benefits from the incorporation of nanoporous materials with high selectivity for I2 ...

Pyridine assisted alkaline desilication has been elaborated as new post-synthetic modification strategy of mordenite. The addition of pyridine during the desilication treatment revealed to impact materials properties through a dual action on textural and chemical properties; substantially differ...

Existing experimental results have shown that multi-step martensite transformation can be induced by the applied stress in single crystal NiMnGa ferromagnetic shape memory alloys (FSMAs) and the transformation property depends on the ambient temperature strongly. In this work, a crystal-plastici...

This work presents direct formulas to compute the HCP elastic constants of ε-martensite from the FCC ones of austenite. The derivation is performed thanks to mechanical compatibility arguments while considering ε-martensite as a laminate structure of twinned and untwinned FCC phases. The formu...

The formation abilities of nano-twin and ε-martensite in Fe-based laser surface modification layer were investigated. The result shows that nano-twin and ε-martensite grow by the overlapping of stacking faults on each and two (111)γ planes respectively. Si atom obviously affects the formation...

Size induced strengthening, i.e. increase in strength with decreasing sample size, has been reported for a variety of single crystal body centered cubic (bcc) materials. However, studies on bcc lath martensite are very limited, in part due to its complex microstructure and the difficulty of smal...

The effect of alloying element Zn on the characteristics of thermal induced martensite and magnetic properties of martensite phase were investigated with scanning electron microscopy (SEM) and Mössbauer spectroscopy characterization techniques. SEM observations revealed that the athermal martens...

The influence of the chemical composition of a NiTi alloy on the martensite stabilization effect was studied. The Ni- 50.0 at. %Ti, Ni – 49.5 at. % Ti and Ni – 49.0 at. %Ti alloys were quenched from 900 °C (10 min) into water and after this heat treatment, the alloys underwent the B2 ↔ B19′ ...

Lath martensite is widely present in advanced high strength steels as the key strengthening phase. Unexpectedly high ductility of lath martensite has been reported in the literature in both single-phase and multi-phase steels, however, without systematic identification of the underlying plastici...

Recent experimental investigations suggest that the martensite formed by quenching carbon steels (0.2–1.26 mass %C) are composed of twins and nanoscale ω particles in twin boundaries, rather than carbon supersaturated uniform solutions. In order to probe the microstructure of the martensite wi...

We present three-dimensional phase-field simulations of martensite microstructure formation in low-carbon steel. In this study, a full set of 24 Kurdjumov-Sachs symmetry variants of martensite is considered. Three different carbon compositions are investigated in order to reveal the effect of ca...

This work generalizes the geometric non-linear, phenomenological theory of martensite crystallography, a time-proven model for the description of martensitic microstructures. Particularly, the case of reconstructive lattice transformation associated with slip is treated as opposed to displacive ...

The aim of this study was to assess the feasibility of using bentonite, illite, and zeolite as capping materials to interrupt the release of and sequestrate carbon, nitrogen, and phosphorus from contaminated sediments. Their efficiency was assessed in batch isotherm, column incubation experiment...

A seed-induced rapid synthesis of submicron ZSM-5 zeolites from acid-leached illite clay was achieved via solid-like state conversion. The optimal synthesis conditions and crystallization mechanism were investigated. The synthesized ZSM-5 zeolites were characterized using X-ray diffraction, scan...

Illite is known to show highly selective Cs adsorption and can control the migration of Cs in a natural environment. However, the local environment and dynamic behavior of Cs with other ions on illite are not well known. To investigate this system, both NMR and theoretical calculation were used ...

The application of a multi-site ion-exchange (MSIE) model to the prediction of contaminant behaviour onto soils or sediments requires a coherent adsorption database. Following the same approach exposed in preceding works on smectite (Siroux et al., Appl. Geochem. 87, 167; Wissocq et al., Appl. G...

Using alkali activation, un-calcined soils have potential as precursors for low carbon, low cost, geopolymer-stabilised construction materials. This technology has been recently promoted as a lower impact alternative to cement stabilisation for walling materials in construction around the world....

Determining the physical conditions and material properties of low-grade (sub-green schist facies) deformation accurately is problematic due to the lack of adequate strain indicators and mineral equilibrium assemblages with established relationships to pressure and temperature conditions. For lo...

This study represents the results of investigations on the possible geopolymer formation of an alkali, mechanically and thermally (including hydrothermally) activated 2:1 layer silicate, namely, illite and illite clay, for low-temperature ceramic products. The main starting materials were Quater...
