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...

The investigation of conductive characteristics and surface structure of polyethylene films modified by fillers was carried out. The dependence of changes in surface and volume resistivity on the quantity of non-metallic...

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...

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...

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...

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...

Abstract Background Metformin has emerged as a potential bioactive agent in regenerative medicine; however, its optimal concentration for enhancing dental pulp stem cell (DPSC) function remains unclear. This study evalua...

Abstract Bone fracture healing requires coordinated regulation of osteogenesis, angiogenesis, and immune homeostasis within a dynamically evolving microenvironment. However, current biomaterials rarely integrate these th...

Ochre pigments, in all their varieties, have played a key role in Northwestern Argentinian pottery for more than 2000 years. Present in different styles, they are combined with other colours on surface paints. This artic...

This work presents, for the frst time, the development of magnetic composites using activated biochar (BC-Act) derived from yerba mate waste. It includes an analysis of the effect of the activation process on the formati...
