Abstract:

The preparation of sweet potato starch phosphates which possess height stable paste was optimized in this study. A central composite design of response surface methodology involving phosphate (sodium dihydrogen phosphate and disodium hydrogen phosphate) concentration, the ratio of sodium dihydrogen phosphate and disodium hydrogen phosphate, phosphorylation temperature and urea concentration was used, and second-order model for paste stability was employed to generate the response surface. The optimum condition for preparation of sweet potato starch phosphates was as follows: phosphate concentr

Abstract:

The plasma electrolytic oxidation(PEO) process of the potassium fluorozirconate electrolyte were investigated with disodium hydrogen phosphate used as additives. Ceramic films were prepared on magnesium alloy in electrolytes with different content of disodium hydrogen phosphate under constant voltage. The effect of disodium hydrogen phosphate on the pH of the electrolyte and the dissolution of the substrate were investigated. It was found that disodium hydrogen phosphate could influence the pH and dissolved magnesium ions significantly.

AbstractFor the purpose of clay examination, a new one-step method for the removal of organic matter was developed using sodium peroxodisulphate combined with different buffers such as sodium hydrogen carbonate, disodium hydrogen phosphate and disodium tetraborate. From an early Cretaceous black shale from the Apennines with a high organic carbon content, the <2 µm clay fraction was separated and contained 10.9 wt% organic carbon. To prevent decomposition of the clay layers, the period of oxidation was short (25-60 min) and the pH was kept between 5 and 9.5. Up to 98% of carbon was removed

Among the calcium phosphate cements, the system based on alpha-tricalcium phosphate (α-TCP) combines several interesting properties.

Abstract:

The reduction of I2 by hydrogen peroxide, a primary water radiolysis product, has been identified as a key reaction that would influence iodine volatility in nuclear reactor accident conditions (13). Although there have been a number of studies of the reduction of I2, there exists a great degree of controversy regarding the intermediates involved, the effect of buffers, and the general rate law (19). Because the rates and the mechanism of this reaction are important in predicting the pH dependence of iodine behaviour in reactor containment building after a postulated reactor accident, we hav

Abstract:

An energy-efficient eutectic hydrated salt phase change material based on sodium carbonate decahydrate and disodium hydrogen phosphate dodecahydrate (SD) was prepared. Then, SD was encapsulated into expanded graphite (EG) to produce form-stable composite phase change materials (SD/E), which indicated a positive effect on preventing the leakage of SD, decreasing the supercooling and improving the thermal conductivity. SD/E was further tested for thermal efficiency by simulating the indoor environment with a house-like model which was composed of SD/E and magnesium oxychloride cement. The result

Abstract:

A method for the simultaneous separation and determination of vanillin ando-vanillin by capillary electrophoresis (CE) was developed. The influence of type, concentration and pH of running buffer, and applied voltage on separation was investigated. Under the condition of 50 mmol/L borax-150 mmol/L disodium hydrogen phosphate (pH 7.5) and applied voltage of 15 kV, the vanillin ando-vanillin were separated in less than 6 min. The method was validated in terms of accuracy, precision and linearity and proved to be robust. This CE method is comparable with high performance liquid chromatography (HP

Abstract:

This study investigates the fabrication and bioactivity of monophasic octacalcium phosphate (OCP) constructs using 3D-printed calcium sulfate precursors. A single-step and a two-step process were employed, transforming calcium sulfate into OCP through a controlled phase transformation in a disodium hydrogen phosphate solution. The results revealed that a single-step process for OCP conversion in 3D printed samples was unsuccessful due to incomplete transformation and the formation of intermediate phases such as brushite and monetite. In contrast, the two-step process enabled the efficient prod

Abstract The grafting reaction of β-cyclodextrin-based microcapsules containing neroline onto pure cotton jersey knitted fabric is studied. The influence of the concentrations of microcapsules, citric acid (CA) crosslinking agent and catalyst on the fabric mass gain was studied to determine the optimum operating conditions. For this purpose, an experimental design based on response surface methodology (RSM) was used leading to the development of a predictive statistical model. The optimal grafting conditions were thus determined: 107.6 g ⋅ L−1 for microcapsules concentration, 111.9 g ⋅ L−1 for

Abstract:

A system was developed for determining dipicolinic acid in “natto” using liquid chromatography with fluorometric detection. The compound was separated by reversed-phase chromatography using a mobile phase of 0.1 mol/L disodium hydrogen phosphate, 0.05 mol/L citric acid buffer (adjusted to pH 3.0) containing 3.0 mmol/L zinc acetate and 35 mmol/L perchloric acid. The compound in the column effluent was irradiated with ultraviolet light to produce fluorescence. This fluorescence was monitored at an excitation at 336 nm and an emission at 448 nm. The calibration curve for dipicolinic acid was obse

Abstract:

Carbonate apatite (CO3Ap) is expected to be an ideal bone substitute since it can harmonize with the bone remodeling cycle. The aim of this study is to fabricate a CO3Ap bone substitute from gypsum (calcium sulfate, CaSO4·2H2O) hardening bodies based on dissolution-precipitation reaction. Calcium sulfate hemihydrate mixed with water at a water-to-powder ratio of 0.5 was packed in a split stainless mold and kept at room temperature for 24 hours to obtain set CaSO4·2H2O. The set CaSO4·2H2O was hydrothermally treated in the presence of disodium hydrogen phosphate (Na2HPO4) and sodium hydrogen car
