Objective: To evaluate the long-term mineralizing effects of an experimental ion-releasing, short fiber-reinforced flowable composite (SFC-active) applied to human teeth with molar–incisor hypomineralization (MIH). M...

ABSTRACT The expansion of the agricultural frontier into different geological environments in the west of the state of Pará, northern Brazil, makes it necessary to know the influence of the parent material on local soil...

As one of composition materials (asphalt, aggregate, mineral powder) for hydraulic asphalt concrete, the mineral powder has a messy process of manufacture. Comparatively, the cement is easily processed and available for ...

Refractories are defined as "non-metallic materials having those chemical and physical properties that make them applicable: for structures, or as components of systems, that are exposed to environments above 1,000 °F (...

Vertical root fractures of intentional replantation need a material capable of binding the fragments of the fracture line tightly and encouraging the regeneration of periradicular tissue. One of the indicators that regen...

Introduction. Magnetic separation is one of the most effective and widely used techniques for the purification and enrichment of materials. It plays a crucial role in mineral processing, recycling, and environmental appl...

Objective: Mineral bone disorders due to chronic kidney disease (CKD-MBD) in children occur as a result of decreased glomerular filtration rate and abnormalities in phosphorus, calcium, parathyroid hormone, and vitamin D...

Mineral-associated organic matter, the dominant form of relatively stable carbon (C) in soil, often co-occurs with reactive iron (Fe) and aluminum (Al) phases across soils. Yet, how organo-metallic associations at the mo...

In recent times, the development of innovative processes permits the application of a circular economy approach to the management and exploitation of mining waste with respect to human health and environment, such that s...

The study explores an eco-efficient synthesis method for hydroxyapatite (HAP) from mineral residues rich in calcium carbonate (CaCO3) and monopotassium phosphate (KH2PO4). The process is based on a chemical reaction in a...

The study of the vapor permeability and surface structure of polyethylene films modified with organic filler(casein) and mixed organic-mineral fillers stored under closed storage conditions have been shown. Changes indif...

Type 2 diabetes mellitus (T2DM) is associated with disturbances in bone metabolism that may increase fracture risk, even in the presence of normal or high bone mineral density (BMD). Dyslipidemia and elevated leptin leve...

El interés por disminuir la cantidad de cemento Portland utilizado en la construcción, surge de la necesidad medioambiental de disminuir las emisiones de CO2 hacia la atmósfera. Inmediatamente aparece la obligación d...

This study presents a novel, modular 3D printing system for the scalable production of microbially induced calcium carbonate (CaCO3) precipitation (MICP) produced bio-materials. Through modular design principles and oper...

Presentamos una síntesis de lo que conocemos hasta el momento sobre las actividades mineras y metalúrgicas prehispánicas desarrolladas en el territorio de la actual provincia de Jujuy (Argentina). Para ello, se analiz...

Presentamos la caracterización tecnológica y composicional de cerámica de estilo Molinos hallada en la localidad de Punta de la Peña en Antofagasta de la Sierra (puna meridional argentina) y en sitios de la cuenca de...

The effect of four commonly consumed beverages as mineral water, coffee, tea and mate tea on the elemental composition of a commercial glass ionomer was studied using Particle Induced X-ray Emission (PIXE) and Rutherford...

Solar iron production from H2-based direct reduction of iron ore was investigated in a continuously particle-fed reactor for performance analysis. Concentrated solar energy was used as the external source of high-tempera...

Heterogeneous catalytic ozonation(HCO) has garnered significant attention in the field of water treatment due to its exceptional capability to mineralize organic pollutants. This technology enhances the degradation and m...

Nickel salts of Keggin heteropolytungstates with the general formula NixAyW12−yO39or40 (A = Si/P) were synthesized and studied as bulk catalytic materials or supported ones by deposition on modified and functionalized ...

The aim of this work was to evaluate the composting process of poultry manure mixed with other complementary organic wastes. Two mixtures (treatment 1 and 2) were prepared with corn bare cobs, sawdust, shavings and manur...
