Abstract:

When biomass of the thermophilic bacteria <em>Geobacillus thermoglucosidasius</em> is brought into contact with a hydrogel containing sodium acetate and strontium, the biomass petrifies and hardens, becoming a mineralized thin film after incubation at 60˚C for 72 h. Analysis by energy dispersive X-ray and X-ray diffraction shows that the mineralized thin film is strontianite. This is the first report of biomass completely changing to strontianite. Strontianite of thermophilic bacterial origin may be formed in the hydrothermal oligotrophic environment of the deep subsurface.

Abstract:

Titanium dioxide-based photocatalysis is a type of advanced oxidation process that can be used to completely degrade and mineralize organic pollutants. The semiconductor titanium dioxide (TiO2) is used as a photocatalyst and is activated when it absorbs photon energy equal or greater than its band gap energy. The activation of TiO2 as a photocatalyst leads to the formation of active sites on its surface that can trigger series of oxidative-reductive reactions to mineralize the pollutants. In most cases, TiO2 is commonly used in slurry form and the recovery of the catalyst after water treatment

Abstract:

The lack of direct bonding between the surface of an implant and the mineralized bony tissue is among the main causes of aseptic loosening in titanium-based implants. Surface etching and ceramic coatings have led to improved osteointegration, but their clinical performance is still limited either by partial bonding or by coating delamination. In this work, a solid-phase synthesis method has been optimized to produce poly(ε-lysine) dendrons, the outermost branching generation of which is functionalized by phosphoserine (PS), a known catalyst of the biomineralization process.

Plasma sprayed coatings composed of stoichiometric hydroxyapatite have been extensively used to improve integration of metallic implants in the host bone, as hydroxyapatite (HA) is normally regarded as similar to the mineralized phase of bone.

On the one hand biological apatite is a carbonated-HA, containing significant amounts of foreign ions, having low crystallinity and a small crystals size. This means that it differs from stoichiometric HA in terms of composition, stoichiometry, crystallinity degree, crystal s

Abstract The in-situ electrochemical corrosion behavior of oil well tubing at 80 °C and 150 °C in highly mineralized oilfield produced water was investigated by conventional electrochemical methods. The results indicated that N80 steel is controlled by charge transfer in the initial-corrosion stage (2-8 h) of 80 °C, and the corrosion rate weakens with the accumulation of corrosion product films. The post-corrosion stage (12-72 h) is controlled by a combination of reactive adsorption and charge transfer, and the adsorbed intermediates lead to enhanced reactive dissolution of the substrate, whic

Collagenase production by rodent osteoblasts in response to calciotropic hormones has led to the hypothesis that bone cells play a major role in bone resorption by degrading the surface osteoid layer, thereby exposing the underlying mineralized matrix to osteoclastic action. Many studies suggest, however, that this model might not apply to bone resorption in the human. Human osteoblasts have been shown to produce gelatinase-A (72 kDa) and TIMP-1 (tissue inhibitor of metalloproteinases), but previous investigators have been unable to demonstrate the synthesis of collagenase by human osteoblasts

Abstract:

The purpose of this study was to evaluate the results of socket preservation after extraction using human particulate mineralized cancellous allograft bone (MCAB) and type I porcine collagen membranes (PCM) as a guided bone regeneration barrier. Fourteen patients, 12 women and 2 men, were selected who had a diagnosis of one or more unsalvageable teeth with a treatment plan to replace them with implant-supported single crown restorations. Extractions were preformed atraumatically by sectioning teeth for removal to avoid damaging the socket walls and by immediately placing MCAB graft to fill the

Abstract:

Humic acid (HA) has complex molecular structure and is capable of adsorption, ion exchange, and chelation with organic and inorganic pollutants in water bodies, worsening water quality and jeopardizing human health and ecological environment. How to effectively remove HA from water is one of the research focuses of this paper. In this study, the UV-activated sodium perborate (SPB) synergistic system (UV/SPB) was established to eliminate HA in water. The effects of initial HA concentration, SPB dose, and initial pH value on the HA elimination were determined, and the main mechanisms of the syne

Abstract:

Dental enamel is the most highly mineralised and hardest biological tissue in human body [1]. Dental enamel is made of hydroxylapatite (HAP) - Ca5(PO4)3(OH), which is hexagonal (6/m). The lattice parameters are a = b = 0.9418 nm und c = 0.6875 nm [1]. Although HAP is a very hard mineral, it can be dissolved easily in a process which is known as enamel demineralization by lactic acid produced by bacteria. Also the direct consumption of acid (e.g. citric, lactic or phosphoric acid in soft drinks) can harm the dental enamel in a similar way. These processes can damage the dental enamel. It will b

It is novelty proposed to use electrochemical oxidation (EO) coupled with BDD anode and nitrate to improve Reactive Red 24 (RR24) removal efficiency in wastewater treatment. The effects of operating parameters in the EO-NO3 −/SO4 2− system on the decolorization efficiency of RR24 were discussed, and the optimal operating parameters were obtained. The energy consumption for 100% decolorization within 15 min is 0.92 kWh m−3, and the total organic carbon (TOC) reaches 51.35% within 90 min. The degradation efficiency is excellent and energy saving. Through the effect of quenchers on RR24 decoloriz

It has almost the same characteristics where the fractures formed are quite large so that it influences the class of rock mass, but the other side is the presence of many fractures which make it easier for scattered mineralization to fill the fracture so that the formed vein is

Abstract The Coles Hill uranium deposit, with an indicated resource of about 130 Mlb of U3O8, is the largest unmined uranium deposit in the United States.

The host rock was metamorphosed to orthogneiss during the Alleghanian orogeny (approx. 325–260 Ma), when it also underwent dextral strike-slip movement along the Brookneal shear zone.

A previously developed laser spallation technique to determine the tensile strength of thin film interfaces was successfully adopted to study the effect of microsurface roughness of titanium disks on the adhesion strength of mineralized bone tissue. The study demonstrated that mineralized tissue has about 25% higher interfacial strength when it is cultured on the acid-etched titanium surface than on its machined counterpart. Specifically, interfacial tensile strength of 179±4.4 MPa and 224±2.6 MPa were measured when the mineralized tissue was processed on the machined titanium and acid-etched
