Study of resin-bonded calcia investment: Part 1. Setting time and compressive strength. (1/25)

This study was carried out to develop a new titanium casting investment consisting of calcia as the refractory material and a cold-curing resin system as the binder. The setting time of the investment was investigated under different N,N-dimethyl-p-toluidine (DMPT) contents in methyl methacrylate monomer (MMA) and benzoyl peroxide (BPO) contents in calcia without any sintering agent. The effects of the sintering agents, which were calcium fluoride (CaF2) and calcium chloride (CaCl2), on the compressive strength of the investments were investigated at room temperature before and after heating to two different temperatures. The shortest setting time (68 minutes) of the investment was obtained at 0.37 DMPT/BPO (1.5 vol% /1.0 mass%) ratio by mass. The highest strength (16.5 MPa) was obtained from the investment which contained 2 mass% CaF2 and was heated to 1,100 degrees C. It was found that the developed calcia investment containing 2 mass% CaF2 has a possibility for use in titanium castings.  (+info)

Study of resin-bonded calcia investment: part 2. Effect of titanium content on the dimensional change of the investment. (2/25)

In the present study, titanium powder was chosen as an expanding agent of an experimentally prepared resin-bonded calcia investment. The effect of Ti content on the dimensional change was investigated. In addition, the effects of the heating rate and heating temperature on the dimensional change of the investment were investigated during setting and after heating. The expansion increased with Ti content and the highest expansion (1.57%+/-0.58) was obtained at 10 mass% Ti. The highest expansion was obtained at 900 degrees C for 30 min heating and was independent of the heating rate. These findings mean that the titanium powder in the calcia investment oxidized sufficiently at that heating condition. It was found that the developed resin-bonded calcia investment was able to compensate for casting shrinkage of pure titanium by adding some Ti powder to the investment.  (+info)

Binding of cations of group IA and IIA to bovine serum amine oxidase: effect on the activity. (3/25)

In this paper, we report on the presence of cation binding areas on bovine serum amine oxidase, where metal ions of the groups IA and IIA, such as Na(+), K(+), Cs(+), Mg(2+), and Ca(2+), bind with various affinities. We found a cation-binding area that influences the enzyme activity if occupied, so that the catalytic reaction may be altered by some physiologically relevant cations, such as Ca(2+) and K(+). This binding area appears to be localized inside the enzyme active site, because some of these cations act as competitive inhibitors when highly charged amines, such as spermine and spermidine, are used as substrates. In particular, dissociation constant values (K(d)) of 23 and 27 mM were measured for Cs(+) and Ca(2+), respectively, using, as substrate, spermine, a polyamine of plasma. An additional cation-binding area, where metal ions such as Cs(+) (K(d) congruent with 0.1 mM) and Na(+) (K(d) congruent with 54 mM) bind without affecting the enzyme activity, was found by NMR.  (+info)

Thermoluminescence in sintered CaF2:Tb. (4/25)

In order to observe and estimate the dose of ultraviolet (UV) radiation, the thermoluminescence (TL) of sintered CaF2 doped with Tb4O7 and Sm2O3 was studied. A several kind of lanthanides elements are doped in pure CaF2 powder crystals and properties of the TL to UV radiation were observed. The TL intensity from CaF2:Tb was the highest among the samples doped other lanthanide elements. The TL emission may be due to the recombination reaction; Tb2+ + hole-->Tb3+*-->Tb3+ + hv. The TL peaks are observed at about 353 K, 378 K and 458 K. It was found that the 378 K TL peak intensity of CaF2:Tb became strong by addition of Sm2O3. The 378 K TL peak may also be suitable for use as a dosimeter.  (+info)

Preparation and properties of nano-sized calcium fluoride for dental applications. (5/25)

OBJECTIVES: The aim of the present study was to prepare nano-sized calcium fluoride (CaF(2)) that could be used as a labile F reservoir for more effective F regimens and as an agent for use in the reduction of dentin permeability. METHODS: Nano-sized CaF(2) powders were prepared using a spray-drying system with a two-liquid nozzle. The properties of the nano-CaF(2) were studied and the effectiveness of a fluoride (F) rinse with nano-CaF(2) as the F source was evaluated. The thermodynamic solubility product of the nano-CaF(2) solution was determined by equilibrating the nanosample in solutions presaturated with respect to macro-CaF(2). Reactivity of the nano-CaF(2) was assessed by its reaction with dicalcium phosphate dehydrate (DCPD). F deposition by 13.2 mmol/L F rinse with the nano-CaF(2) as the F source was determined using a previously published in vitro model. RESULTS: X-ray diffraction (XRD) analysis showed pattern of low crystalline CaF(2). BET measurements showed that the nano-CaF(2) had a surface area of 46.3m(2)/g, corresponding to a particle size of 41nm. Transmission electron microscopy (TEM) examinations indicated that the nano-CaF(2) contained clusters comprising particles of (10-15) nm in size. The nano-CaF(2) displayed much higher solubility and reactivity than its macro-counterpart. The CaF(2) ion activity product (IAP) of the solution in equilibrium with the nano-CaF(2) was (1.52+/-0.05)x10(-10), which was nearly four times greater than the K(sp) (3.9 x 10(-11)) for CaF(2). The reaction of DCPD with nano-CaF(2) resulted in more F-containing apatitic materials compared to the reaction with macro-CaF(2). The F deposition by the nano-CaF(2) rinse was (2.2+/-0.3)mug/cm(2) (n=5), which was significantly (p<0.001) greater than that ((0.31+/-0.06)mug/cm(2)) produced by the NaF solution. SIGNIFICANCE: The nano-CaF(2) can be used as an effective anticaries agent in increasing the labile F concentration in oral fluid and thus enhance the tooth remineralization. It can also be very useful in the treatment for the reduction of dentin permeability.  (+info)

TiF(4) varnish-A (19)F-NMR stability study and enamel reactivity evaluation. (6/25)

The aim of this study was to develop a titanium tetrafluoride (TiF(4)) varnish and evaluate the stability of the formulation and its reactivity with dental enamel. The varnish was prepared in a resinous matrix using ethanol 96% as solvent. Samples (n=45) were aged at 65 degrees C and 30% of relativity humidity (RE n degrees 01/05-ANVISA) and after 3, 6, 9 and 12 months, nine samples were removed for evaluation and compared with fresh samples. Chemical stability of TiF(4) varnish was determinate by (19)F-NMR and the reactivity of the formulation was quantified by formation of fluoride loosely (CaF(2)) and firmly bound (fluorapatite; FA) to enamel. For reactivity comparisons, a varnish without TiF(4) was used as control. The loss of soluble fluoride was about 0.9% after one year of storage. The values of the reactivity (mean+/-S.D.) of fresh, aged at 3, 6, 9 and 12 months and control samples were: CaF(2) (microg F/mm(2)): 89.3+/-27.5(a); 54.5+/-14.3(b); 51.2+/-29.8(b); 69.3+/-21.3(a); 48.0+/-27.4(b); 0.10+/-0.07(c), FA (microg F/g): 2477.5+/-1044.0(a); 2484.8+/-992.0(a); 2580.0+/-1383.9(a); 2517.2+/-929.9(a); 2121.0+/-1059.2(a); 330.0+/-180.0(b), respectively. Means followed by distinct letters were statistically different (p<0.05). After one year of storage, the formulation was chemically stable and the levels of FA were maintained. However there was an initial decrease in the ability to form CaF(2).  (+info)

The adsorption of methylene blue (MB) onto pore-expanded calcium fluoride sludge (ECF) by the batch adsorption technique was investigated. The results showed that the adsorption capacity increased with increasing MB concentration but decreased as pH was increased. In order to investigate the adsorption mechanisms, three simplified isotherm models and kinetic models were used in this study. The best-fit adsorption isotherm was achieved with the Temkin model. Furthermore, the pseudo-second-order kinetic model agreed very well with the dynamical behavior for the adsorption of MB onto ECF. Thermodynamic studies revealed that the adsorption process of MB onto ECF was spontaneous and exothermic. The results indicated that ECF adsorbed MB efficiently and could be used as a waste adsorbent for the removal of cationic dyes in wastewater treatment ...
The high temperature combustion of hydrogen and oxygen is used to transform halogenated refrigerant gases (HRGs) and halons to produce calcium fluoride salts. Calcium carbonate is also produced by a series of chemical processes. Calcium chloride is partially consumed by the process by reaction with fluoride released during the high temperature combustion of the HRGs. Calcium chloride is also produced in the process during scrubbing of chlorine and during the recovery of ammonia used to remove carbon dioxide. The calcium chloride produced during the process can be used in the combustion reaction to further produce calcium fluoride.
A study of nuclear relaxation due to paramagnetic impurities has been made, using the system of F19 nuclei in Ca F 2. T1 was measured at helium, hydrogen, and nitrogen temperatures. The field dependence of T1 at helium temperatures consists of three parts: at fields less than a few hundred gauss, the dependence of T1 on the field is parabolic; between a few hundred gauss and about 2.5 Kg, the dependence is linear; and at higher fields, it is linear, but has a steeper slope. Moreover, there is a strong orientation dependence in the helium range for a single crystal, and a size effect appears at higher fields. At temperatures above 14°K, T1 has only a weak orientation dependence. The experimental data indicate that T1 is minimum between 14°K and 63°K. An analysis of the experimental results with existing theories permits a determination of the field and temperature dependence of the relaxation time rho of the spin of the paramagnetic impurity. The analysis gives rho ∼ H-2T-1 for ...

With no less than five (5) of its 10 elements made of calcium fluoride, it truly is an exotic lens. By comparison, perhaps one or two of Canons finest lenses might be made of fluoride. In addition, the lens coatings are 12-layers and designed to handle that 315-1100nm range-conventional lens coatings attenuate huge portions of that spectral band. Even the Zeiss ZF Prototype lenses use a simpler coating optimized only for infrared.. A few other exotic lenses exist in the rarefied territory of UV-capable lenses, including the Nikon 105/4 UV-Nikkor (long since discontinued), the Pentax 85/4.5 Ultra apochromatic (circa 1975), and the (medium format) Hasselblad/Zeiss 105/4.3 UV-Sonnar. There exist other specialty lenses, most of which were made in very small numbers (and of varying optical performance), but its a safe bet that few to none of them offer the versatility and high performance from UV through infrared that the Coastal 60/4 APO does, especially once one considers the MTF performance and ...

Recycle of radioactive scrap metals (RSM) from decommissioning of DOE uranium enrichment and nuclear weapons manufacturing facilities is mandatory to recapture the value of these metals and avoid the high cost of disposal by burial. The scrap metals conversion project detailed below focuses on the contaminated nickel associated with the gaseous diffusion plants. Stainless steel can be produced in MSC`s vacuum induction melting process (VIM) to the S30400 specification using nickel as an alloy constituent. Further the case alloy can be rolled in MSC`s rolling mill to the mechanical property specification for S30400 demonstrating the capability to manufacture the contaminated nickel into valuable end products at a facility licensed to handle radioactive materials. Bulk removal of Technetium from scrap nickel is theoretically possible in a reasonable length of time with the high calcium fluoride flux, however the need for the high temperature creates a practical problem due to flux volatility.

The piezobirefringence of calcium fluoride, barium fluoride, strontium fluoride, gallium arsenide, and cadmium fluoride has been measured in the infrared over the wavelength range 3.5 to 11 micrometers. A large dispersion was found in the coefficients of the fluorides; moreover, some of the coefficients were observed to reverse sign. The data for GaAs showed a small yet significant dispersion. The data for the alkaline-earth fluorides were fitted to a three parameter strain-dependent oscillator representation of the infrared-active transverse-optic (TO) phonon; the predominant contribution to the dispersion comes from the strain-induced TO phonon splitting; estimates were made to the strain-induced oscillator strength anisotropy. The GaAs data were fitted to the same model but with only two free parameters; here the predominant contribution to the dispersion came from the estimated strain-induced oscillator strength anisotropy of the TO phonon; the experimental data agree fairly well with the theory of
Potassium salts diffuse along dentinal tubules working to decrease the excitability of intradental nerve fibers by blocking axionic action. Potassium citrate 5%, potassium citrate 5.5%, and potassium chloride 3.75% can be used interchangeably and are more effective than fluoride alone.2 Potassium nitrate 5% is most commonly found in the United States because it is the only ingredient approved by the FDA and validated for the relief of sensitivity by interruption of neural response to pain stimuli.3 Studies show potassium nitrate 5% must be used twice daily for at least two weeks for a measurable reduction in sensitivity, and four to eight weeks for pain reduction.2 The downside of potassium salts is solubility; the ingredient is only effective when potassium ion concentrations remain high.1 If this ingredient is effective in reducing a patients dentin hypersensitivity, continued long-term use can be recommended..

Fluoride (F) varnishes are effective in preventing caries and reducing dentin sensitivity. The addition of calcium (Ca) and phosphate (PO4) salts may influence the F release rate and also induce formation of calcium/phosphate/fluoride as persistent F reservoirs. The hypothesis is that F release rate can be optimized with the F content and the addition of Ca and PO4 salts. Objectives: To study the effect of the F content and the Ca and PO4 salts on the ion release and precipitation of F varnishes. Methods: The varnish containing 1670 ppm or 22600 ppm fluoride with or without Ca salt (10%) and PO4 salt (5.8%) was painted on a 2x2 cm plastic substrate and immersed in a 0.03 mol/L NaCl solution (n=3). The released ions were measured with pH, Ca, and F electrodes under slow stirring at 22 oC for 3 days. The concentrations of Ca and PO4 were analyzed by spectrophotometric methods. The precipitated calcium phosphate fluoride was characterized with X-ray Powder Diffraction and Scanning Electron ...

1. Introduction. In recent years there has been much attention given to polymer-clay nanocomposites, particularly those developed with layered silicates due to the need of more efficient engineering materials, and because of the fact that pure polymers do not present the properties needed for certain applications. Several methods have been applied for the preparation of polymer-clay nanocomposites, such as melting intercalation, the most used among them1.. Polymeric nanocomposites are hybrid materials where inorganic nanosized substances are dispersed in a polymer matrix2-3. Polymer layered silicate nanocomposites are compared to conventional polymeric composites due to the use of fillers to improve some specific properties1. Such nanocomposites present improvement on mechanical, thermal, flammability and dimensional stability properties, using low concentrations of silicate, around 1-5% by weight4.. From the surveys conducted by the Toyota group which developed polyamide 6 nanocomposites using ...

This article reviews nanocomposites focusing on their impact and recent trends in the field of bone grafting. Although autogenous- and allogeneic-bone grafts have been used for a long time in bone therapies, there is still a donor shortage and infection risk. As an alternative, synthetic biomaterials have been developed and clinically used as bone grafts, but most of them differ substantially from natural bone either compositionally or structurally. It remains a great challenge to design an ideal bone graft that emulates natures own structure. Owing to the composition and structural similarity to natural bone, most of the current investigations involve the use of nanocomposites, particularly hydroxyapatite/collagen system, as promising bone grafts, but it is surprising that none of the reports review the rationale and design strategy of such nanocomposites in detail for the benefit of researchers. Accordingly, this article addresses the state-of-the-art of those nanocomposites and provides ...
Lithium-ion batteries designed for use in heavy-duty hybrid vehicles are continuously improved in terms of performance and longevity, but they still have limitations that need to be considered when developing new hybrid vehicles. The aim of this thesis has been to study and evaluate potential test and analysis methods suitable for being used in the design process when maximizing lifetime and utilization of batteries in heavy-duty hybrid vehicles.. A concept for battery cell cycling on vehicles has been evaluated. The work included development of test equipment, verification of hardware and software as well as an extended period of validation on heavy-duty trucks. The work showed that the concept has great potential for evaluating strategies for battery usage in hybrid vehicles, but is less useful for accelerated aging of battery cells. Battery cells encapsulated in flexible packaging material have been investigated with respect to the durability of the encapsulation in a demanding heavy-duty ...

Polymer nanocomposites with practically all the commercial polymer matrices have been synthesized and nano-scale filler dispersion has been achieved with varying degrees of success. The commercial polymer nanocomposites studied to a great extent are unfortunately non-biodegradable like polyethylene, polypropylene and polystyrene etc. To a small extent, these nanocomposites are reformed or recycled into other products after one life cycle, however, the properties of such recycled materials are very poor. Therefore, subject of bio-based nanocomposites and biodegradable nanocomposites has become topic of interest in the recent years and a number of suitable bio-based and biodegradable polymer matrices have been developed and their property enhancement have been reported after the incorporation of the inorganic filler materials. These systems include poly(lactic acid), poly(butyl succinate), alginate, cellulosic plastics, gelatine, starch, soy protein based polymers, plant oil based polymers, poly

TY - JOUR. T1 - Experimental evidence for reduced chain segment mobility in poly(amide)-6/clay nanocomposites. AU - Miltner, Hans E.. AU - Rahier, Hubert. AU - Pozsgay, András. AU - Pukánszky, B.. AU - Van Mele, Bruno. PY - 2005. Y1 - 2005. N2 - Poly(amide)-6/clay nanocomposites are investigated by means of modulated temperature differential scanning calorimetry. The importance of polymer-filler interaction is explored by comparing nanocomposites based on untreated and organically modified clay. During quasi-isothermal crystallization experiments, an excess contribution is observed in the recorded heat capacity signal due to reversible melting and crystallization. The magnitude of this excess contribution depends on the nanocomposite investigated. We suggest that it is directly related to the segmental mobility of the polymer chains in the interphase region. As such, the magnitude of this excess contribution can be used to quantify the efficiency of the polymer-clay interaction. Depending on ...
Varnish stores data in virtual memory and leaves the task of deciding what is stored in memory and what gets paged out to disk to the operating system. This helps avoid the situation where the operating system starts caching data while it is moved to disk by the application. Varnish is heavily threaded, with each client connection being handled by a separate worker thread. When the configured limit on the number of active worker threads is reached, incoming connections are placed in an overflow queue; when this queue reaches its configured limit incoming connections will be rejected. The principal configuration mechanism is Varnish Configuration Language (VCL), a domain-specific language (DSL) used to write hooks that are called at critical points in the handling of each request. Most policy decisions are left to VCL code, making Varnish more configurable and adaptable than most other HTTP accelerators.[citation needed] When a VCL script is loaded, it is translated to C, compiled to a shared ...
For their research, Gilani and her team cut 40 wood samples in the direction of the grain. 20 of these samples were taken from the young wood and the other 20 from the heartwood of a Norway spruce. Gilani and her colleagues also cut a further 20 samples from the same spruce across the grain. Based on these three types of test samples, the researchers were able to study the sound behaviour of different wood structures. Johanna Pflaum, a trained violin maker, student of environmental sciences and member of Gilanis research group, created two varnishes in the lab. The research group also received two further varnishes from German violin makers. Gilani coated the spruce samples with these four varnishes. For each type of sample, five of the twenty pieces of wood were coated with the same varnish and were dried and cured for eleven hours using UV light.. However before this, the researchers measured the stiffness and sound insulation of the wood samples in their raw state and the mass of the ...

Objective: The capability of drinks and foods to resist pH changes brought about by salivary buffering may play an important role in the erosion of dental enamel. The aim of the present study was to measure the initial pH of several types of yogurt and to test the degrees of saturation (pK-pl) with respect to hydroxyapatite and fluorapatite to determine the buffering capacity and related erosive potential of yogurt. Method and Materials: Twenty-five milliliters of 7 types of freshly opened yogurt was titrated with 1 mol/L of sodium hydroxide, added in 0.5 mL increments, until the pH reached 10, to assess the total titratable acidity, a measure of the drink s own buffering capacity. The degrees of saturation (pK-pl) with respect to hydroxyapatite and fluorapatite were also calculated, using a computer program developed for this purpose. For statistical analysis, samples were compared using Kruskal-Wallis test. Results: The buffering capacities can be ordered as follows: fruit yogurt > low-fat ...
After their discovery in 1991 by Iijima [1], carbon nanotubes (CNTs) have attracted considerable interest because of their unique as well as superior physical, electrical, magnetic, chemical stability, thermal conductivity and mechanical properties [2]. Due to their exceptionally high aspect ratio and mechanical properties, incorporation of small amounts of CNTs into a polymer matrix is expected to enhance the properties of the resulting nanocomposites more than any existing material. The most critical issue of CNTs/polymer nanocomposites is the adhesion/compatibility between the nanotubes and polymer which ultimately controls the interface between the CNTs and the polymer matrix. Unfortunately pure CNTs are insoluble in any organic solvents and they tend to form agglomerates because of strong Van der Wall forces which results in negative effects on the properties of the resulting nanocomposites. As such achieving a high degree of dispersion of CNTs in any polymer matrix is quite a challenging ...

Through the use of custom-engineered synthetic proteins known as monobodies, scientists have resolved the atomic structure of the fluoride ion channel, revealing a unique double-barreled architecture that contains two pathways through which fluoride ions flow -- a potentially new mechanism of ion transport. The study, published in Nature, sheds light on the evolution of these channels and enables new approaches to modify their function, with potential applications such as the development of novel antibiotics.
