Preparation and Characterization of Novel α-Naphthol Luminophors for Optoelectronic Devices.

Luminophors of α-Naphthol doped with varying concentrations of anthracene and perylene were prepared by conventional solid state reaction method to explore its fluorescence characteristics. The fluorescence spectra of bicomponent and tricomponent luminophors reveals the fluorescence excitation energy transfer (FRET) process. The prepared bi and tri component luminophors were excited at 290nm which corresponds to host excitation wavelength. The weak violet fluorescence of host, α-Naphthol, gets quenched and give anthracene like emission in bicomponent luminophor systems. Further doping with second host, perylene, in anthracene containing α-Naphthol luminophors, red shifted emission was observed at 605nm. The structural parameters, thermal stability and electrical properties of doped luminophors were studied by using X-ray diffraction, TGA-DSC and Cyclic Voltammetry respectively. The particle size of the prepared luminophors was confirmed by scanning electron microscopy (SEM).

Upconversion photoluminescence of Er-doped Bi$_{4}$Ti$_{3}$O$_{12}$ ceramics enhanced by vacancy clusters revealed by positron annihilation spectroscopy

Abstract Doping of rare earth elements into Bi$_{4}$Ti$_{3}$O$_{12}$ can significantly enhance the upconversion photoluminescence (UCPL) properties, but its structure-property relationship is still unclear. In this work, Er-doped bismuth titanate Bi$_{4-x}$Er$_{x}$Ti$_{3}$O$_{12}$ ($x$=0, 0.1, 0.2, 0.3, 0.4, 0.5) ceramics were synthesized via solid-state reaction method. The X-ray diffraction analysis confirmed the orthorhombic crystalline structure of the Bi$_{4-x}$Er$_{x}$Ti$_{3}$O$_{12}$ ceramics without any secondary phases. Experiments and calculations of positron annihilation spectroscopy were carried out to characterize their defect structure. The comparison between the experimental and calculated lifetime revealed that vacancy clusters were the main defects in the ceramics. The increase of the intensity of the second positron lifetime component (I$_{2}$) of Bi$_{3.5}$Er$_{0.5}$Ti$_{3}$O$_{12}$ ceramics indicated the presence of a high concentration of vacancy clusters. The UCPL spectra shown the sudden enhanced UCPL performance in Bi$_{3.7}$Er$_{0.3}$Ti$_{3}$O$_{12}$ and Bi$_{3.5}$Er$_{0.5}$Ti$_{3}$O$_{12}$ ceramics, which were consistent with the variation of the second positron lifetime component (I$_{2}$). These results indicate that the enhanced UCPL properties are influenced not only by the concentrations of rare earth ions but also by the concentration of vacancy clusters present within the ceramics.

Lattice constant, bandgap energy, absorption coefficient and dielectric function of the antimony-rich InBixSb1-x alloy using first-principles calculations

So far, little is known about the electronic and optical properties of InBixSb1-x. In this work, the first-principles calculations are performed to research the lattice constant, the bandgap energy, the absorption coefficient and the dielectric function of the antimony-rich InBixSb1-x. The results show that the bowing coefficient for the lattice constant is merely −0.012 Å. According to the band structures, it is found that the Sb-rich InBixSb1-x possesses a direct bandgap at G point. Its bandgap reduction is due to the ascending of the valence band maximum (VBM) and the descending of the conduction band minimum (CBM). For the sake of providing a good description for the bandgap energy in the Sb-rich range, the modified valence band anticrossing (MVBAC) model plus a linear equation is utilized. The result shows that the predicted positive to negative bandgap transition occurs at x = 0.13. Besides, the valence band offset between InSb and InBi is identified to be 0.27eV. For the optical properties, it is found that the Bi component is effective in raising the static dielectric constant of InBixSb1-x. However, it has a minor effect on the transition ability of the electrons. In the Sb-rich component range, the critical point energies E0+Δ0E1, E1+Δ1E2 and E1′ are found to shift toward the low energy direction. The result of the absorption spectra supports this opinion as increasing Bi component leads to a redshift of the absorption spectra. The adjustable bandgap energy and the optical properties of InBixSb1-x demonstrate that it is a strong candidate for fabricating the photodetectors in the 8–12 μm spectral region.

Нерелятивистское приближение в 39-компонентной теории для частицы со спином 2

The goal of the present paper is investigation of the nonrelativistic approximation in the 39-component theory for a spin 2 particle. We apply explicit expressions for four main matrices Γa with dimension 39×39 in the relevant first-order system of equations, written in Cartesian coordinates and in presence of external electromagnetic fields. For distinguishing the large and small constituents in the complete wave function, we apply three projective operators constructed on the base of the minimal polynomial of the 7-th order for the matrix Γ0. The relevant large and small components are found in explicit form. In each group, we have found independent variables; in particular, among the large components there exist only five independent ones. We have derived the nonrelativistic equation for 5-component wave function; it has the term describing interaction of the magnetic moment of the spin 2 particle with the external magnetic field we distinguished. This additional term is constructed by the projections of spin operator Si and the components of the magnetic field Bi.

Promoted photocatalytic N2 fixation to ammonia over floatable TiO2/Bi/Carbon cloth through relay pathway

The floatable photocatalyst at N2-water interface allows the adequate supply of N2 reactant and the utilization of photothermal energy for photocatalytic N2 fixation, however, the presence of non-volatile NO3− product poses a challenge to the stability as it easily covers the catalytic active sites. Herein, a floatable TiO2/Bi/CC (Carbon cloth) photocatalyst was designed, in which the non-volatile NO3− can be transformed to the volatile NH3 via the newly synergistic relay photocatalysis pathway (N2 → NO3− → NH3) between TiO2 (N2 → NO3−) and Bi (NO3− → NH3). Attractively, the spontaneous NO3− → NO2− step occurs on Bi component to promote the relay pathway performing. Therefore, TiO2/Bi/CC system displays better long-term stability than TiO2/CC, and moreover, it achieves a higher NH3 yield of 8.28 mmol L−1 h−1 g−1 (i.e. 4.14 mmol h−1 m−2) than that 1.46 mmol L−1 h−1 g−1 for TiO2/Bi powder. Importantly, the N2 fixation products by TiO2/Bi/CC effectively promote lettuce growth and enhance lettuce nutrient contents, which further validates the feasibility of this system in large-scale application of crop cultivation.

Thermophysical Properties of Cu-Based Subsystems of High-Entropy Alloys

According to the well-known concept of multicomponent high-entropy alloys, high entropy of mixing can stabilize the formation of solid solutions (simple bcc or fcc crystal structure) during solidification. Stabilization of the solid solution and prevention of the formation of intermetallic phases during solidification is provided by the high entropy of mixing in the solid and liquid states. High-entropy alloys have increased strength, high hardness, thermal stability in combination with good resistance to oxidation and corrosion. These properties allow to significantly expand the scope of these alloys. In this work, the electrical resistivity, thermoelectric power and surface tension of binary Cu–Sn, Cu–Ga and Cu–Bi alloys, which are the sub-system components of model low-temperature high-entropy Bi–Cu–Ga–Pb–Sn alloys, have been studied in a wide temperature range including solid and liquid states. The lack of the surface tension data of the above-mentioned alloys is compensated by the model predicted values.

A Safe Organic/Inorganic Composite Anode for Sodium‐Ion Batteries

AbstractSodium‐ion batteries (SIBs), based on hard carbon anodes and Na+‐intercalation compound cathodes, have gained significant attention. Nonetheless, hard carbon anodes involve the storage of Na+ at a low potential, typically below 0.1 V (vs Na/Na+), which increases the risk of dendritic Na growth on the anode surface during overcharging. Herein, a safe organic/inorganic composite anode containing tetrasodium 3,4,9,10‐perylenetetracarboxylate (Na4PTC) and Metallic bismuth (Bi) with a weight ratio of 7:2, which exhibits an average potential of 0.7 V (vs Na+/Na) and a capacity of 150 mAh g−1 is proposed. The electrode reaction involves a reversible coordination reaction within the organic host and alloying reactions within the metallic Bi component. Importantly, the organic component efficiently buffers the volume changes in Bi during the alloying reaction, while the metallic Bi enhances the electronic conductivity of the organic material. As a result, this composite anode shows high cycle stability and rate performance, even under high mass loadings ranging from 10 to 50 mg cm−2. Furthermore, it is demonstrated that the Na‐ion full cell, consisting of the composite anode and the Na3V2O2(PO4)2F cathode, exhibits minimal capacity degradation over 100 cycles while maintaining a high areal capacity of 1.1 mA cm−2.

Novel BCZT-based ceramics with ultrahigh energy storage efficiency and outstanding high temperature fatigue endurance and stability for practical application

Dielectric ceramic capacitors with superior energy storage efficiency and ability to operate in high temperature environments (T∼200 °C) are urgently needed for practical application. In this study, a relaxor component of Bi(Zn2/3Nb1/3)O3 (BZN) was massively doped into Ba0.85Ca0.15Zr0.1Ti0.9O3 (BCZT) ceramic to improve energy storage properties and ability to operate in high temperature. The massive introduction of Bi(Zn2/3Nb1/3)O3 optimizes dielectric relaxor behavior, enhances bandgap width, refines grain size and improves electrical homogeneity, which can significantly increase breakdown strength (Eb), decrease remanent polarization (Pr) and broaden dielectric constant peak. Here, the 0.75BCZT-0.25BZN ceramic possesses an ultrahigh energy storage efficiency (∼96.8%) with a large recoverable energy density (∼2.39 J/cm3) under a medium applied field (260 kV/cm). In addition, the optimum sample exhibits prominent thermal stability within 20∼200°C and dielectric temperature stability (ΔC/C25°C ≤ ± 15%, −63∼234°C) in accordance with X9R. More critically, the same composition was firstly measured fatigue endurance at 200°C and possesses excellent fatigue stability. The above results demonstrate that the optimum sample has potential for practical application in high temperature environments.

Rational designed novel TiO2-x/Bi6Cr2O15/Bi quantum dots: Bi-based plasmonic photocatalysts for boosted detoxifying organic and inorganic wastewaters under visible light

We combined brown TiO2-x with Bi6Cr2O15 and Bi using a facile procedure to fabricate Bi-based plasmonic TiO2-x/Bi6Cr2O15/Bi photocatalysts for detoxifying organic and inorganic wastewaters upon visible light. The TEM and HRTEM analyses provided strong evidence for the construction of quantum dots of the photocatalyst with diameter of almost 8.2 nm and intimate contact among TiO2-x, Bi6Cr2O15, and Bi components. The TiO2-x/Bi6Cr2O15/Bi nanocomposites exhibited boosted activity in the degradation of tetracycline (TC), azithromycin (Azi), rhodamine B (RhB), methylene blue (MB), and photoreduction of Cr (VI) pollutants, and the performance was 12.9, 1.67, 10.4, 3.50, and 6.91-folds greater than TiO2-x, and 19.1, 1.60, 3.44, 2.88, and 1.90-times higher than Bi6Cr2O15 photocatalysts, respectively. In particular, h+ and •OH species were identified as the key species involved in the TC degradation reaction. The electrochemical analyses, including EIS, Bode plots and photocurrent density, and PL spectroscopy exhibited efficacious segregation and transportation of charge carriers within the ternary photocatalyst. Finally, the biocompatibility of TC-treated solution over the TiO2-x/Bi6Cr2O15/Bi photocatalyst was verified by the growth of lentil seeds.

Leveraging Ligand and Composition Effects: Morphology-Tailorable Pt-Bi Bimetallic Aerogels for Enhanced (Photo-)Electrocatalysis.

Metal aerogels (MAs) are emerging porous materials displaying unprecedented potential in catalysis, sensing, plasmonic technologies, etc. However, the lack of efficient regulation of their nano-building blocks (NBBs) remains a big hurdle that hampers the in-depth investigation and performance enhancement. Here, by harmonizing composition and ligand effects, Pt- and Bi-based single- and bimetallic aerogels bearing NBBs of controlled dimensions and shapes are obtained by facilely tuning the metal precursors and the applied ligands. Particularly, by further modulating the electronic and optic properties of the aerogels via adjusting the content of the catalytically active Pt component and the semiconducting Bi component, both the electrocatalytic and photoelectrocatalytic performance of the Pt-Bi aerogels can be manipulated. In this light, an impressive catalytic performance for electro-oxidation of methanol is acquired, marking a mass activity of 6.4-fold higher under UV irradiation than that for commercial Pt/C. This study not only sheds light on in situ manipulating NBBs of MAs, but also puts forward guidelines for crafting high-performance MAs-based electrocatalysts and photoelectrocatalysts toward energy-related electrochemical processes.

Self-Supporting Bi-Sb Bimetallic Nanoleaf for Electrochemical Synthesis of Formate by Highly Selective CO2 Reduction.

Electrocatalytic reduction of CO2 into valuable fuels and chemical feedstocks in a sustainable and environmentally friendly manner is an ideal way to mitigate climate change and environmental problems. Here, we fabricated a series of self-supporting Bi-Sb bimetallic nanoleaves on carbon paper (CP) by a facile electrodeposition method. The synergistic effect of Bi and Sb components and the change of the electronic structure lead to high formate selectivity and excellent stability in the electrochemical CO2 reduction reaction (CO2RR). Specifically, the Bi-Sb/CP bimetallic electrode achieved a high Faradic efficiency (FEformate, 88.30%) at -0.9 V (vs RHE). The FE of formate remained above 80% in a broad potential range of -0.9 to -1.3 V (vs RHE), while FECO was suppressed below 6%. Density functional theory calculations showed that Bi(012)-Sb reduced the adsorption energy of the *OCHO intermediate and promoted the mass transfer of charges. The optimally adsorbed *OCHO intermediate promoted formate production while inhibiting the CO product pathway, thereby enhancing the selectivity to formate synthesis. Moreover, the CO2RR performance was also investigated in a flow-cell system to evaluate its potential for industrial applications. The bimetallic Bi-Sb catalyst can maintain a steady current density of 160 mA/cm2 at -1.2 V (vs RHE) for 25 h continuous electrolysis. Such excellent stability for formate generation in flow cells has rarely been reported in previous studies. This work offers new insights into the development of bimetallic self-supporting electrodes for CO2 reduction.

Enhanced photoactivity and selectivity over BiOI-decorated Bi2WO6 microflower for selective oxidation of benzylamine: Role of BiOI and mechanism

The importance of developing effective and selective photocatalytic materials to realize efficient renewable energy-based organic synthetic processes, such as selective oxidation of benzylamines and its derivatives to the corresponding imines has become more apparent in recent years. Here we present the first reported BiOI/Bi2WO6 (BI/BW) microflower heterostructure as a visible-light-driven photocatalyst for such reactions. By decorating the hydrothermally prepared BW with BI via successive ionic layer adsorption and reaction (SILAR) method, benzylamine conversion is improved from 68 % to 92 % as compared to undecorated. Furthermore, selectivity to desired imine product is substantially increased from 59 % to 95 %. These outstanding performances are attributed to enhanced electron-hole separation and transfer efficiency as well as a greater preference for adsorption of benzylamine compared to the imine products and extended visible-light absorption range inherited from BI component as supported by competitive adsorption studies, ultraviolet–visible diffuse reflectance spectroscopy, and photoelectrochemical experiments. Possible mechanisms, band energy diagram, and decisive roles of O2− and h+ in the selective transformation of benzylamine were proposed based on Mott-Schottky, scavenging, and electron paramagnetic resonance radical trapping experiments. This work highlights a simple approach for improving photocatalytic activity and selectivity which are highly desirable in renewable energy-based chemical synthetic processes.

Is fixation of the medial malleolus necessary in unstable ankle fractures?

It is unclear whether the medial malleolus in unstable bi- and tri- malleolar ankle fractures without medial talar displacement should be addressed surgically. This study reviews a fixation protocol for the medial malleolar component of unstable bi- or tri- malleolar ankle fractures. Two hundred fifty-seven patients who sustained bi- (AO/OTA 44-B2) or tri- (AO/OTA 44-B3) malleolar ankle fractures between January 2005 and August 2019 at two Level 1 trauma centers were retrospectively identified. Medial malleolar fractures were defined as anterior, supra or intercollicular fractures based on the exit of the posterior fracture line. Fixation of the medial malleolar component was performed based on surgical algorithm. Only large or significantly displaced medial malleolar fractures were fixed if the soft tissues were amenable. Primary outcome measure was the presence of medial-sided ankle pain after operative or non-operative treatment of the medial malleolar fracture after a minimum follow up of 6months. Presence of pain was defined by a pain score of 3 or higher on a 10-point VAS pain score at the site of the medial malleolar fracture. Significantly more patients in the supracollicular group reported the presence of pain when this type was not fixed versus fixed (28 vs 14%, p = 0.0094). Significantly more patients in the anterior collicular subgroup reported the presence of pain when this type was fixed versus not fixed (40 vs 10%, p = 0.0438). There was no difference in the number of patients reporting pain in the intercollicular group when comparing those who were fixed versus not fixed, (21 vs 22%, p = 1.000). When examining post-operative pain, not all medial malleolar fractures require fixation when appropriately selected based on fracture pattern. Only 10% of patients with anterior collicular fractures reported pain after non operative management. Unsurprisingly, more patients in the supracollicular fractures reported pain without surgery compared to with surgery. Fracture pattern should be considered in the treatment algorithm for the medial malleolar component in bi- and tri- malleolar fractures.

Functionalized hybridization of bismuth nanostructures for highly improved nanophotonics

Bismuth (Bi) has achieved remarkable progress due to its intriguing physicochemical properties, such as low toxicity, controllable stability, tunable bandgap, superior optical response, and strong diamagnetism. Bi-based hybrids have drawn increasing attention in recent years due to the integrated features of the Bi component and the synergistic effect on the separation and transfer of charges, holding great promises for versatile applications. In this Perspective, we systematically review the recent progress on the controlled synthesis of Bi-based heterostructures and their improved nanophotonic performances compared with those of mono-element Bi counterparts and present the existing challenges and future opportunities. It is anticipated that this Perspective can shed light on new designs of high-performance functional Bi-based heterostructures to meet the growing demand for next-generation nanophotonic systems.

Synthesis of acrylic acid through aldol condensation of acetic acid with formaldehyde catalyzed by Bi‐,W‐ and Cs‐doped B2O3/SiO2 nanocomposites

AbstractBACKGROUNDAcrylic acid commercially produced by the successively catalytic oxidation of propylene has a high cost. The synthesis of acrylic acid by aldol condensation between coal derivatives, acetic acid and formaldehyde, is an economic alternative to the propylene oxidation process. However, the development of an environmentally friendly and effective catalyst has remained a challenge.RESULTSDiboron trioxide [B2O3(6–20%)]/silica (SiO2) nanocomposites with B2O3 particle sizes of 1–2 nm prepared by the wetness impregnation of boric acid into silica aerogel and subsequent calcination at 500 °C effectively catalyzed the gas‐phase aldol condensation reaction between acetic acid and formaldehyde (trioxymethylene) to acrylic acid with a selectivity of ≈87% at 340–400 °C. Bismuth (Bi‐), tungsten (W‐) and caesium (Cs)‐doped B2O3/SiO2 nanocomposites had higher catalytic activities in the gas‐phase aldol condensation reaction to acrylic acid than the undoped B2O3/SiO2 nanocomposite.CONCLUSIONWeak‐strength Lewis acid and alkali sites of the B2O3(6–20%)/SiO2 nanocomposites co‐catalyzed the aldol condensation reaction to form acrylic acid. The doping of B2O3/SiO2 nanocomposites with Bi, W and Cs components results in the formation of BiBO3, WO3 and CsBO2 phases, which lead to an increase in acidity and basicity resulting in higher catalytic activity in the formation of acrylic acid. © 2022 Society of Chemical Industry (SCI).

Abstract: Self-service Business Intelligence (SSBI) is an emerging topic for many companies. Casual users should be enabled to independently build their own analyses and reports. This accelerates and simplifies the decision-making processes. Although recent studies began to discuss parts of a self-service environment, none of these present a comprehensive architecture. Following a design science research approach, this study proposes a new self-service oriented BI architecture in order to address this gap. Starting from an in-depth literature review, an initial model was developed and improved by qualitative data analysis from interviews with 18 BI and IT specialists form companies across different industries. The proposed architecture model demonstrates the interaction between introduced self-service elements with each other and with traditional BI components. For example, we look at the integration of collaboration rooms and a self-learning knowledge database that aims to be a source for a report recommender.

Improvement of Oxygen Reduction Performance in Alkaline Media by Tuning Phase Structure of Pd-Bi Nanocatalysts.

Tuning the crystal phase of bimetallic nanocrystals offers an alternative avenue to improving their electrocatalytic performance. Herein, we present a facile and one-pot synthesis approach that is used to enhance the catalytic activity and stability toward oxygen reduction reaction (ORR) in alkaline media via control of the crystal structure of Pd-Bi nanocrystals. By merely altering the types of Pd precursors under the same conditions, the monoclinic structured Pd5Bi2 and conventional face-centered cubic (fcc) structured Pd3Bi nanocrystals with comparable size and morphology can be precisely synthesized, respectively. Interestingly, the carbon-supported monoclinic Pd5Bi2 nanocrystals exhibit superior ORR activity in alkaline media, delivering a mass activity (MA) as high as 2.05 A/mgPd. After 10,000 cycles of ORR durability test, the monoclinic structured Pd5Bi2/C nanocatalysts still remain a MA of 1.52 A/mgPd, which is 3.6 times, 16.9 times, and 21.7 times as high as those of the fcc Pd3Bi/C counterpart, commercial Pd/C, and Pt/C electrocatalysts, respectively. Moreover, structural characterizations of the monoclinic Pd5Bi2/C nanocrystals after the durability test demonstrate the excellent retention of the original size, morphology, composition, and crystal phase, greatly alleviating the leaching of the Bi component. This work provides new insight for the synthesis of multimetallic catalysts with a metastable phase and demonstrates phase-dependent catalytic performance.

Carbon Xerogel Nanostructures with Integrated Bi and Fe Components for Hydrogen Peroxide and Heavy Metal Detection.

Multifunctional Bi- and Fe-modified carbon xerogel composites (CXBiFe), with different Fe concentrations, were obtained by a resorcinol–formaldehyde sol–gel method, followed by drying in ambient conditions and pyrolysis treatment. The morphological and structural characterization performed by X-ray diffraction (XRD), Raman spectroscopy, N2 adsorption/desorption porosimetry, scanning electron microscopy (SEM) and scanning/transmission electron microscopy (STEM) analyses, indicates the formation of carbon-based nanocomposites with integrated Bi and Fe oxide nanoparticles. At higher Fe concentrations, Bi-Fe-O interactions lead to the formation of hybrid nanostructures and off-stoichiometric Bi2Fe4O9 mullite-like structures together with an excess of iron oxide nanoparticles. To examine the effect of the Fe content on the electrochemical performance of the CXBiFe composites, the obtained powders were initially dispersed in a chitosan solution and applied on the surface of glassy carbon electrodes. Then, the multifunctional character of the CXBiFe systems is assessed by involving the obtained modified electrodes for the detection of different analytes, such as biomarkers (hydrogen peroxide) and heavy metal ions (i.e., Pb2+). The achieved results indicate a drop in the detection limit for H2O2 as Fe content increases. Even though the current results suggest that the surface modifications of the Bi phase with Fe and O impurities lower Pb2+ detection efficiencies, Pb2+ sensing well below the admitted concentrations for drinkable water is also noticed.

ELECTRICAL AND THERMAL CONDUCTIVITY AND PHONON CONTRIBUTION TO THE THERMAL CONDUCTIVITY IN THE BI-IN SYSTEM

In this study, the contribution of phonon to the thermal conductivity in the In-Bi (Indium-Bismuth) system due to its composition variation was determined from their electrical and thermal conductivity measurements. Because of the common usage of In-Bi system in many technological applications, thermal and electrical conductivity variations with temperature for different compositions of Bi component were measured. Four-Point Probe (FPP) and Linear Heat-Flow (LHF) methods were used for electrical and thermal conductivity measurements respectively. Intermetallic systems' electrical conductivity values were determined between 0.8524 (1/Ω m) ×106 and 2.8381(1/Ω m) ×106 and thermal conductivity values were found between 14.50 (W/Km) and 35.93 (W/Km) at the melting temperature. Electron and phonon contributions to the thermal conductivity were calculated by using Wiedemann-Franz Law (WFL) from the measured values. The temperature coefficients values () of electrical and thermal conductivity were calculated between 0.46-2.54 (K-1) x10-3 and 1.29-4.34 (K-1) x10-3 respectively. In order to observe microstructure of the Bi-In intermetallic alloy Scanning Electron Microscopy (SEM) and to determine the composition of the phases in the structures, Energy Dispersive X-Ray Analysis (EDX) were used. Also melting temperatures (349.03 K-387.24 K), enthalpy of fusion (17.97 J/g- 42.37 J/g) and specific heat change (0.159 J/gK-0.372 J/gK) of Bi-In alloy systems were measured by using Differential Scanning Calorimeter (DSC).
