CAS[20548-54-3] FLAMMABLE However, it is worth noting that the (200) and (111) rock-salt peaks coincide with the (222) and (400) π-phase peaks, so we cannot exclude the possibility that the rock-salt phase also exists. Compared to films deposited by Ca(F-amd)2 and Sn(A-amd)2, films deposited by Ca(F-amd)2 and Sn(F-amd)2 showed smoother and more compact film morphology at the same deposition temperature of 160 and 190 °C. Figure 3 compares the calcium content measured by XPS with predictions from a simple additive model using the individual SnS and CaS ALD growth rate. High-quality SnS and CaS thin films have been successfully deposited by ALD using various precursors [Reference Sinsermsuksakul, Heo, Noh, Hock and Gordon9, Reference Baek, Pyeon, Song, Chung, Kim, Baek, Kim, Kang, Choi, Hwang, Han and Kim22, Reference Bilousov, Ren, Törndahl, Donzel-Gargand, Ericson, Platzer-Björkman, Edoff and Hägglund23, Reference Rautanen, Leskela, Niinisto, Nykhen, Soininen and Utriainen33, Reference Hanninen, Mutikainen, Saanila, Ritala and Leskela34, Reference Kim, Yang, Powers, Davis, Lou and Gordon35, Reference Park, Heasley, Sun, Steinmann, Jaramillo, Hartman, Chakraborty, Sinsermsuksakul, Chua, Buonassisi and Gordon36, Reference Catherall, Harris, Hill, Johnson and Mahon37, Reference Yang38]. Events, Alternating SnS and CaS cycles were deposited on thermal oxide substrates using Sn(A-amd)2 and Ca(F-amd)2, respectively, as the cation precursor and H2S as the sulfur precursor. "crossMark": true, To view updated drug label links, paste the RSS feed address (URL) shown below into a RSS reader, or use a browser which supports RSS feeds, such as Safari for Mac OS X. RxNorm, This could be caused by phase separation into SnS and CaS at high temperature, which agrees with the thermodynamic argument by Vidal et al. ... and tin metal. Thus, we postulate that ternary film deposition in ALD benefits from selecting precursors of the same ligands. "isLogged": "1", Absorption spectra of the films were measured using a Hitachi U-4100 UV–Vis–NIR spectrophotometer.

Figure 8: (a) Resistivity of (Sn,Ca)S samples with different Ca content deposited at 160 and 135 °C, as-deposit (solid) and after annealing (unfilled). *TIN SULPHIDE is alchemist's gold. Place tablets under tongue at least 15 minutes before or 30 minutes after eating, brushing teeth, or drinking anything except water. Abstract We deposit films of tin–calcium sulfide by atomic layer deposition (ALD) and demonstrate the metastability of this material. Rock-salt SnS has been mostly obtained by solution processing methods at low temperatures of less than 80 °C [Reference Garcia-Angelmo, Romano-Trujillo, Campos-Álvarez, Gomez-Daza, Nair and Nair19, Reference Chalapathi, Poornaprakash and Park20, Reference Breternitz, Gunder, Hempel, Binet, Ahmet and Schorr21]. Furthermore, if a significant portion of the Sn in the previously deposited SnS was replaced by Ca, the crystal lattice would be disturbed and roughing of the film would not be unexpected. Children under 12 years of age: Consult a doctor. As shown in Fig. Get Label RSS Feed, The answer will appear below; Always use the upper case for the first character in the element name and the lower case for the second character. 5 Chemical Vendors. In hotter water that diminishes to 1/100th (0.01) of a single percent. Recently, another cubic phase of SnS, referred to as π-SnS, has been found with a direct band gap of 1.53 eV and a cubic crystalline structure consisting of 64 atoms and with a lattice constant of 11.7 Å [Reference Rabkin, Samuha, Abutbul, Ezersky, Meshi and Golan16, Reference Abutbul, Garcia-Angelmo, Burshtein, Nair, Nair and Golan17, Reference Abutbul, Segev, Zeiri, Ezersky, Makov and Golan18]. The y-axis represents the percentage of Ca in the cation mix of Sn + Ca, and the bottom spectrum represents pure SnS. Clinical Trials, I tried to make that too, but the reaction apparently didn't happen or is not stoichiometric, because it made grey stuff that keeps stinking like rotten eggs. Updated Two kinds of tin sources were used: bis(N,N′-diisopropylacetamidinato)tin(II) and bis(N,N′-diisopropylformamidinato)tin(II), referred to as Sn(A-amd)2 and Sn(F-amd)2, respectively. A newly developed Ca precursor has significantly lowered the CaS ALD temperature window to 150–275 °C, which allows an overlap of the CaS and SnS ALD windows and, thereby, enabling (Sn,Ca)S alloy formation using layer-by-layer deposition of SnS and CaS [Reference Kim, Yang, Powers, Davis, Lou and Gordon35]. Due to inconsistencies between the drug labels on DailyMed and the pill images provided by RxImage, we no longer display the RxImage pill images associated with drug labels. October 14, 2020. It would be 2 KBr + CaS == K2S + CaBr2. These shifts indicate a slight lattice contraction caused by smaller calcium atoms occupying some of the tin sites. Vidal et al. Figure 1 shows the morphology of films deposited with a SnS:CaS cycle ratio of 20:1 at four different temperatures between 160 and 245 °C. "shouldUseHypothesis": true, }. "metricsAbstractViews": false, Published online by Cambridge University Press: ‒ In aluminum-killed, calcium treated steels, inclusions are typically compounds comprising Al 2 O 3, CaO, MgO, CaS, MnS, and TiN components ‒ Sulfur contents lower than 10 ppm are recommended to avoid back-modification of calcium aluminates into Al 2 O 3 (or MgO.Al 2 O 3) during continuous casting ‒ Excess calcium treatment makes Furthermore, the SnS:CaS cycle ratio was varied from 35:1 to 5:1 at a fixed temperature of 212 °C to study the effect on composition. "hasAccess": "1", Figure 7(a) shows the in-house high-resolution X-ray diffraction (HRXRD) spectra of approximately 120 nm of (Sn,Ca)S films deposited at 160 °C with five different compositions. Instructions on balancing chemical equations: Enter an equation of a chemical reaction and click 'Balance'. Zooming into a smaller region, we can see that the three peaks between 31° and 33° have slight positive shifts compared to the reference peaks for pure SnS. "isUnsiloEnabled": true Thus, despite the apparently high content of Ca, the cation replacement needs to only happen for less than 3/4 of topmost monolayer of SnS during the Ca(F-amd)2 dose to reach a Ca/(Ca + Sn) value of 0.62, which is not unreasonable. ECS-0335765. Identify the spectator ions Ca2+ and S2-Ca2+ and Na+ NO3- and Na+ Ca2+ and NO3. Feature Flags last update: Thu Jan 14 2021 04:57:08 GMT+0000 (Coordinated Universal Time) "lang": "en" This data will be updated every 24 hours. The (Sn,Ca)S alloy films were deposited in a custom-built hot-wall ALD reactor by alternating SnS and CaS cycles using the recipe [(SnS)m–(CaS)]n, where m and n were integers used to adjust the composition and thickness of the film, respectively. Over the 10-12,000 gallon lifetime of our shower filter cartridges, less than 6/100ths (0.06) of 1% will dissolve, but that is only in the coldest water (0ºC/32ºF). Yet, one should still note that the QCM experiment has its own limitations in simulating actual film growth inside an ALD reactor. These approximate materials prices are published to provide budgetary guidelines. Helps loosen phlegm (mucus) and thins bronchial secretions, relieves bronchial congestion. PubMed, Copyright © Materials Research Society 2019, Hostname: page-component-77fc7d77f9-w9qs9 Dispelling the myths behind the hyperbole Calcium sulfite, or CaSO3, as used in water filtration systems, is largely insoluble in water. This slight difference can be overcome by alloying SnS with CaS, at Ca fractions in excess of 0.18. This activity includes every compound formula and name that can be formed from the list 44 Ions provided in Chemistry A at Pickerington High School Central. Given the SnS growth rate of 0.33 Å/cycle, it takes at least 12 cycles to grow one monolayer of SnS. We can see in Fig. showed that orthorhombic SnS can be converted into rock salt type by alloying with CaS [Reference Vidal, Lany, Francis, Kokenyesi and Tate28]. I want to find out more about that. An SEM image of a 500-nm thick alloy film deposited at 190 °C shows the layered film with plate-shaped grains more clearly [Fig. Titanium Nitride (TiN) inclusions are commonly observed in a Maraging steel containing Nitrogen and Titanium and remelted in a VAR furnace. One possible hypothesis of such a morphology difference is that the roughness could result from an uneven competition for the surface –SH groups between F-amd and A-amd ligands. This research was supported in part by the Center for the Next Generation of Materials by Design, an Energy Frontier Research Center funded by the U.S. DOE, Office of Science. write the chemical equation for any reaction. Figure 6 shows that the Ca contents are again higher than the values calculated from the separate growth rates of SnS and CaS using Ca(F-amd)2 and Sn(F-amd)2, indicating the presence of cation replacement as discussed in section “Film deposition using Sn and Ca precursors with different ligands”. A thicker film (600 nm) with composition near the phase transition (33% Ca) was deposited at 135 °C and examined by the synchrotron-based 2DXRD, which has higher resolution and beam intensity and can, thus, reveal more details in its crystal structure. After Ca(F-amd)2 dose and purge of excess precursor, mass gain in the ternary film was 40% less than that in bulk CaS. As a potential solution, the cubic phase of SnS has been investigated since the 1960s, although the phase assignment to rock salt or zinc blende has been debated [Reference Badachhape and Goswami11, Reference Mariano and Chopra12, Reference Avellaneda, Nair and Nair13, Reference Gao, Shen and Sun14, Reference Burton and Walsh15]. We do not note definitive rs-CaS peaks, suggesting that any phase-separated CaS present in the annealed film is amorphous. In this structure, (Sn,Ca)S film was sandwiched between Mo growth substrate and sputtered ITO. Citations, Report Adverse The crystallographic structure and lattice parameters of the α-SnS, rs-SnS, and π-SnS are shown in Fig. Molar mass of CaS = 72.143 g/mol. Given that XPS data showed 5× higher Ca content than prediction under this deposition condition, we suspect that significant amount of cation replacement of Sn by Ca might have happened during the Ca(F-amd)2 dose. One probable explanation is that as Ca atoms are incorporated into the SnS film, they occupy the Sn vacancies (V Sn), which is the major source of p-type conductivity [Reference Albers, Haas, Vink and Wasscher5, Reference Abrikosov, Bankina, Poretskaya, Shelimova and Skudnova6, Reference Vidal, Lany, d’Avezac, Zunger, Zakutayev, Francis and Tate7]. Both phenomena could be explained by phase separation of the metastable alloy. Because the mixing enthalpy is in the order of 100 meV, there should exist a miscibility gap under thermodynamic equilibrium conditions. This suggests the possibility of phase separation under certain conditions. As a new Sn precursor was being developed using the same F-amd ligand as the Ca precursor, we deposited the (Sn,Ca)S film again with Sn(F-amd)2 and Ca(F-amd)2 as the cation precursors, in an attempt to improve the film quality. Figure 6: Composition of (Sn,Ca)S deposited by Ca(F-amd)2 and Sn(F-amd)2 (a) at different temperatures using SnS:CaS dosing ratio of 20:1 and (b) using SnS:CaS dosing ratio ranging from 10:1 to 30:1 at substrate temperature of 212 °C. Second, the α-SnS has an indirect band gap of 1.1 eV and a direct band gap exceeding 1.3 eV, which tends to reduce the achievable open-circuit voltage by up to 0.2 eV [Reference Vidal, Lany, d’Avezac, Zunger, Zakutayev, Francis and Tate7, Reference Tritsaris, Malone and Kaxiras8, Reference Sinsermsuksakul, Heo, Noh, Hock and Gordon9, Reference Miles, Ogah, Zoppi and Forbes10]. To examine the cause, we investigated the growth mechanism of the (Sn,Ca)S ternary film using a quartz crystal microbalance (QCM), which measured the in situ mass changes of the growing film. Figure 7(b) shows the 2DXRD spectrum of an as-deposited and annealed film. I wonder if I can make a ring out of IRON SULFIDE (fools gold). Adults and children 12 years of age and older: 2 tablets every 2 hours until relieved. We found that (Sn,Ca)S transforms from an orthorhombic phase to a cubic phase as the Ca content increases. Crystal structure of the films is characterized before and after a high-temperature annealing process. They have the same structure as sodium chloride, with each atom having six neighbours. Ca(F-amd)2 would be consumed much faster when the Ca cations replace the Sn cations than growing only one layer of CaS alone as in bulk CaS growth, which is consistent with the faster depletion of Ca precursor across the furnace at high temperature. Schneider, Nathanaelle One may attribute this to less effective adsorption of Ca(F-amd)2 onto a surface finished with –Sn–S–H groups from previous SnS growth cycles. Crystal structure of the films is performed using both high-resolution X-ray diffraction (HRXRD; Bruker D8) (Cu Kα radiation, λ = 1.542 Å) θ–2θ scans and synchrotron-based 2DXRD (λ = 0.9744 Å) at beamline 11–3. Cycle numbers are chosen so that the film thickness is 100–200 nm. Figure 2 shows the composition and uniformity of the as-deposit ternary films estimated from X-ray photoelectron spectroscopy (XPS), as denoted by the atomic ratio of Ca/(Ca + Sn). Similar ion exchange processes have been observed in the atomic layer deposition of other metal sulfide systems [Reference Thimsen, Peng, Martinson, Pellin and Elam39]. These precursor compounds were heated to temperatures sufficient to provide enough vapor for growing films: Sn(A-amd)2 was maintained at 95 °C, Sn(F-amd)2 at 65 °C, and Ca(F-amd)2 at 135–140 °C. CaS has an odor of rotten eggs, which stems from H 2 S formed by hydrolysis of the calcium sulfide. In summary, (Sn,Ca)S alloy films with controllable composition were deposited by ALD using alternating cycles of H2S alternating with Ca(F-amd)2, Sn(A-amd)2, or Sn(F-amd)2. is this? Tin monosulfide solar cells have attracted increasing attention as a potential low-cost and environmental friendly substitute for the commercial thin-film solar cells based on CdTe and CIGS [Reference Ramakrishna Reddy, Koteswara Reddy and Miles1, Reference Sinsermsuksakul, Hartman, Kim, Heo, Sun, Park, Chakraborty, Buonassisi and Gordon2, Reference Sinsermsuksakul, Sun, Lee, Park, Kim, Yang and Gordon3, Reference Jaramillo, Steinmann, Yang, Hartman, Chakraborty, Poindexter, Castillo, Gordon and Buonassisi4]. The encoded transporter plays a role in regulation of intracellular calcium levels and transports L-type amino acids. 1 Structures Expand this section. "openAccess": "0", This means that I dont have to remove spectator ions? Although both carrier concentration and hole mobility were increased upon annealing, they are still not ideal for solar cell absorbers. The pure SnS film demonstrates two sets of characteristic doublet peaks at around 27° and 31°, respectively. Files, Presentations Query parameters: { } The one emerging from the double peaks at 27° corresponds to the (111) peak of rs-SnS, and the one from the doublet peaks at 31° is found between the rs-CaS and rs-SnS peaks. The crystal structure transforms from orthorhombic to cubic as the calcium content increases. & Articles, All As-deposited thin films are annealed at 400 C for 1 h in H2S/N2 environment at a pressure of 4 torr. Compositional and quartz crystal microbalance results indicate that part of the underlaying SnS film is replaced and/or removed during the CaS ALD cycle during the ternary film deposition, possibly via a temperature-dependent cation exchange mechanism. After removing the precipitates by filtering, calcium sulfide or barium sulfide is added to remove another heavy metal contaminant as sulfides. and Tin sulfide (SnS) is a candidate absorber material for Earth-abundant, non-toxic solar cells. View Labeling Archives, [Reference Abutbul, Garcia-Angelmo, Burshtein, Nair, Nair and Golan17, Reference Abutbul, Segev, Zeiri, Ezersky, Makov and Golan18]. and the risks of emission of toxic hydrogen sulfide. Recently, a phase diagram was proposed for (Sn,Ca)S films, showing a transition from an orthorhombic phase to a cubic phase as calcium content increased [Reference Holder, Siol, Ndione, Peng, Deml, Matthews, Schelhas, Toney, Gordon, Tumas, Perkins, Ginley, Gorman, Tate, Zakutayev and Lany27, Reference Vidal, Lany, Francis, Kokenyesi and Tate28, Reference Matthews, Holder, Schelhas, Siol, May, Forkner, Vigil-Fowler, Toney, Perkins, Gorman, Zakutayev, Lany and Tate29]. Contents. But the equilibrium lies to the left (reactants favored) since CaS is the least soluble among the participants, and will precipitate out. Le Tulzo, Harold "clr": true, The quartz crystal was placed near the inlet of the precursors. The cation exchange reaction between Ca(F-amd)2 precursors and underlaying SnS can be described as: Figure 4: (a) Mass changes as measured by QCM during (Sn,Ca)S deposition using SnS:CaS dose ratio of 15:1. Calcium has a density of 1.54 g/cc, a melting point of 839°C, and a vapor pressure of 10-4 Torr at 459°C. Calcium is an essential building block for human life as it is found in abundance in human skeletons and teeth. However, we were more surprised to see that after H2S dose and purge, there was also approximately twice the amount of mass loss, leading to a net mass loss during the CaS deposition cycle. Files, All Mapping Field emission scanning electron microscopy (FESEM; Zeiss Supra55VP) was used to examine film morphology and estimate thickness. The protein exists as the heavy chain of a heterodimer, covalently bound through di-sulfide bonds to one of several possible light chains. "peerReview": true, Oxygen can be combined with various cations to form a large number of ionically bonded solids. Our record SnS solar cell was deposited using in-house developed Sn(II) precursors at substrate temperatures lower than 200 °C [Reference Sinsermsuksakul, Sun, Lee, Park, Kim, Yang and Gordon3, Reference Yang38]. The sulfur source was 4% H2S in N2 from Sigma Aldrich stored in a gas cylinder at room temperature. * Views captured on Cambridge Core between 22nd November 2019 - 14th January 2021. Rough and spiky films are obtained by using Sn and Ca precursors with different ligands, whereas compact and smooth films are obtained when the two metal sources share the same ligands. Cobalt will react because it is the only element above Ni in the activity series The growth substrate in QCM experiment is coated with gold, resulting to a different crystallographic orientation as compared with bulk SnS deposition on Mo or SiO2 substrates that were used for all our other depositions. If you are a consumer or patient please visit However, the delay itself is insufficient to explain the 5× higher Ca content, and more QCM data in fact showed no noticeable delay in SnS growth immediately after the CaS cycle. The assignment of peaks around 31° is less definitive because several peaks from different phases crowd into that region. which metals, if any, will react? The number of times each element appears as a reactant and as a product the same. Detailed time dependence of the deposition process shows that the previously deposited SnS is partially removed by calcium precursor vapor, which partially explains why the Ca contents in the alloy films are higher than those predicted from the separately measured growth rates of pure SnS and pure CaS. The protein exists as the heavy chain of a heterodimer, covalently bound through di-sulfide bonds to one of several possible light chains. Figure 1: Cross-sectional SEM of (Sn,Ca)S deposited by Ca(F-amd)2 and Sn(A-amd)2 at different substrate temperatures: (a) 160 °C, (b) 190 °C, (c) 212 °C, and (d) 245 °C. "shouldUseShareProductTool": true, The latter one is performed at the Stanford Synchrotron Radiation Lightsource (SSRL). In this study, we report ALD of rock-salt (Sn,Ca)S films with controllable composition at relatively low substrate temperatures. The growth rates are estimated to be 6.3, 5.7, and 4.7A per super cycle. High-resolution X-ray diffraction (XRD) was performed on the alloy films, and the peak positions were compared with simulated diffraction peak positions of α-SnS, rs-SnS, π-SnS, and CaS to determine the crystal structure of the alloy films. this mixture is mixed with nickel nitrate.

Alternatively, there are reports of π-SnS deposited by atomic layer deposition (ALD) at temperatures up to 200 °C, but the π phase only dominates in films less than 100 nm thick, which is not surprising given that π-SnS is thermodynamically less stable than α-SnS. Films deposited at 160 °C have resistivities in the range of 102–104 Ω cm, but films deposited at 135 °C demonstrate much higher resistivities, possibly because of their smaller grain size and columnar-shaped grains which are aligned perpendicular to growth substrates.

Donsanti, Frédérique DailyMed will deliver notification of updates and additions to Drug Label information currently shown on this site through its RSS feed. Heating calcium with silicon, phosphorus, or graphite in the absence of air gives calcium silicides (Ca 2 Si, CaSi, and CaSi 2), calcium phosphide (Ca 3 P 2), and calcium carbide (CaC 2), respectively. Although we operated in the overlapping ALD temperature windows of SnS and CaS as shown in previous studies [Reference Sinsermsuksakul, Heo, Noh, Hock and Gordon9, Reference Kim, Yang, Powers, Davis, Lou and Gordon35], rough and spiky films were obtained over a wide range of temperatures and film smoothness decreased with increasing temperature.

Resistivities of films deposited at 135 and 160 °C were measured using the van der Pauw method. Solubility Product Constants near 25 °C. If pregnant or breast-feeding, ask a healthcare professional before use. Presence in Breast Milk, Medline Plus, Biochemical Data Summary. The peaks corresponding to different crystal structures are labeled by different markers. Figure 2: Composition at different locations in the hot-wall tube ALD reactor of the (Sn,Ca)S film deposited at different temperatures. E g is determined using the equation (αhν)n = A(hν − E g ± E ph), where A is a constant, n is the transition probability (n = 2 for direct-allowed transition and n = 1/2 for indirect-allowed transition), and E ph is the phonon energy [Reference Ritter and Weiser40]. The rough and spiky morphology renders the films formed by Ca(F-amd)2 and Sn(A-amd)2 unsuitable for solar cell applications. This observation is difficult to explain in the conventional ALD context nor by our proposed cation replacement hypothesis. White, decomposes upon melting. Figure 3(a) shows that the alloy films deposited at all temperatures had higher Ca content than the additive model prediction, where the atomic ratio of Ca/(Ca + Sn) was calculated to be 0.12. 5(d)]. This is consistent with the QCM data, where the Ca dose/purge step led to a net mass gain that is lower than what the mass gain would be without the cation exchange.
