Contaminated soil with high mobility of potentially toxic elements (PTEs) can threaten the environment and human health. Precisely quantifying trends in PTEs accumulation under changing pH conditions is essential to minimize potential exposure. However, this has long been a hard-to-monitor subject experimentally due relatively low content lack detailed knowledge minerals that control PTEs' leaching. Here we profoundly investigate critical role mineralogy release predict leaching behavior by...
World plastic production has increased since industrial-scale began in the 1940s and while large amount of thermoplastic polymers can be effectively recycled re-used, undifferentiated or thermoset cannot, as a result, most these raw materials end up landfill energy recovery incinerators. The synthesis carbon nanomaterials from conversion waste is an alternative, promising approach owing to high added-value products. In particular, novel materials, could translate into interesting cheap...
Significance The origin of diamonds in ureilites is still a debated issue among the scientific community, with significant implications for sizes early Solar System bodies. We investigated three diamond-bearing by multimethodological approach using scanning electron microscopy, micro X-ray diffraction, transmission and micro-Raman spectroscopy, aim determining diamonds. Our results show that formation both microdiamonds nanodiamonds can be explained impact shock events on small planetesimal...
In this work, the factors controlling fresh state properties of limestone calcined clay cement (LC3) are assessed and compared to Portland binary cements, extending scope previous research by combining rheological measurements with setting time determination evaluation plastic shrinkage a novel method. Yield stress elastic modulus considered indicators for structural build-up/breakdown process when is applied system. On other hand, occurs from mixing paste plays an important role in...
Identifying immobilization mechanisms of potentially toxic elements (PTEs) is paramount importance in the field application solidification/stabilization. Traditionally, demanding and extensive experiments are required to better access underlying retention mechanisms, which usually challenging quantify clarify precisely. Herein, we present a geochemical model with parametric fitting techniques reveal solidification/stabilization Pb-rich pyrite ash through conventional (ordinary Portland...
Metal–carbon interaction plays a fundamental role in tuning the electrocatalytic behavior of metal nanoparticles (NP). The aim this study is to emphasize effective synergy between sulfur doping and porous structure carbon support on Pt NPs morphology dimension. Thiophenic-like defects exert metal-support that affects nucleation growth their catalytic activity, versus oxygen reduction reaction (ORR), which makes them promising candidates for cathode side PEMFC defectivity, size, size...
Natural Hydraulic Lime (NHL) binders are generally preferred to those cement-based in case of restoration works, thanks their good compatibility with historical substrates. Moreover, they can be considered more sustainable comparison cement, being sintered at lower temperatures. Nonetheless, while having a historic substrates, performance might need improvement terms strength values and development without sensibly affecting stiffness.To this purpose, the incorporation Graphene Oxide (GO)...
Calcium-silicate hydrate (commonly referred to as C–S–H in cement chemistry) is the main phase and "glue" of hydrated cement, binding matrix building materials such concrete, which an essential commodity for modern infrastructures housing. The basic mechanisms that control hydration modes formation are not fully understood picture becomes even more complicated when organic polycarboxylate-based additives (PCE) added with aim controlling rheology fresh paste strength final product. Here, a...
The study of hydration kinetics by in‐situ X‐ray powder diffraction can provide fundamental details on the time evolution phase assemblage in hydrating cement pastes. main limit technique is lack quantitative information about amount C–S–H and unbound water, which cannot be measured directly conventional analysis procedures based diffraction, due to their amorphous nature. Here, a mass balance algorithm, used determine both capillary presented compared with methods standards. This method...
Abstract The metal–support interactions between sulfur‐doped carbon supports (SMCs) and Pt nanoparticles (NPs) were investigated, aiming at verifying how sulfur functional groups can improve the electrocatalytic performance of NPs towards oxygen reduction reaction (ORR). SMCs synthetized, tailoring density groups, deposited by thermal Pt(acac) 2 . extent interaction was proved X‐ray photoelectron spectroscopy (XPS) analysis, which revealed a strong electronic interaction, proportional to...
