Author - Shaheed U. Shaikh, Farha Y. Siddiqui, Fouran Singh, Pawan K. Kulriya, D.M. Phase, Ramphal Sharma.

Abstract - The CdS–Bi2S3 bi-layer thin films have been deposited on Indium Tin Oxide (ITO) glass substrates at room temperature by Chemical Bath Deposition Technique (CBD) and bi-layer thin films were annealed in air atmosphere for 1 h at 250 °C. The air annealed sample was irradiated using Au9+ ions at the fluence 5 × 1011 ion/cm2 with 120 MeV energy. Effects of Swift Heavy Ion (SHI) irradiation on CdS–Bi2S3 bi-layer thin films were studied. The results are explained on the basis annealing and high electronic excitation, using X-ray diffraction (XRD), Selective Electron Area Diffraction (SEAD), Atomic Force Microscopy (AFM), Raman Spectroscopy, UV spectroscopy and I–V characteristics. The photosensing property after illumination of visible light over the samples is studied. These as-deposited, annealed and irradiated bi-layer thin films are used to sense visible light at room temperature.

Abstract -  Considering the potential applications of transition metal doped nanostructured materials and the advantages of novel, cost-effective and environmentally friendly biosynthesis methods, Ni-doped SnO2 nanomaterials have been synthesized using remnant water (ideally kitchen waste) collected from soaked Bengal gram bean (Cicer arietinum L.) extract. The structural and optical properties of the Ni-doped SnO2 nanostructures were studied using various techniques such as UV/visible spectroscopy, FT-IR spectroscopy, X-ray powder diffraction (XRD), field-emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM). The SEM and TEM images and the XRD results of the biosynthesized Ni–SnO2 nanoparticles reveal a uniform size distribution with an average size of 6 nm and confirmed the formation of a rutile structure with the space group (P42/mnm) and the nanocrystalline nature of the products with a spherical morphology. Subsequently, Ni-doped biosynthesized SnO2 nanoparticles were coated onto a glass substrate using the doctor blade method to form thin films. The NO2 sensing properties of the materials have been studied in comparison with other gases. The reported gas sensing results are promising, which suggest that the Ni-dopant is a promising noble metal additive to fabricate low cost SnO2 based sensors.

Author - D. R. Sapate, C. M. Kale, A. A. Pandit and K. M. Jadhav,

Abstract - (x) CoFe2O4 + (1 − x) Ba0.9Sr0.1TiO3 magnetoelectric (ME) composites with x = 0.1, 0.2, 0.3, 0.4 and 0.5 were prepared by a conventional standard double sintering ceramic method. The magnetic and ME properties of composites consisting of cobalt ferrite (CoFe2O4) and barium strontium titanate (Ba0.9Sr0.1TiO3) were investigated. The X-ray diffraction analysis was carried out to confirm the phases formed during sintering and also to calculate the lattice parameters. The hysteresis measurements were done to determine saturation magnetization (Ms), remanence magnetization (Mr) and coercivity (Hc) of the samples. The ME voltage coefficient (dE/dH)H was studied as a function of intensity of the magnetic field. The measured ME response demonstrated strong dependence on the volume fraction of CoFe2O4 and the applied magnetic field. A large ME voltage coefficient of about 1,380 µV/cm/Oe was observed for 10 % CoFe2O4 + 90 % Ba0.9Sr0.1TiO3 composite.


Synthesis, structural investigation and magnetic properties of Zn substituted cobalt ferrite nanoparticles prepared by the sol–gel auto-combustion technique.

Author - V. Raut, R. S. Barkule, D. R. Shengule, K. M. Jadhav

Abstract - Structural morphology and magnetic properties of the Co1−xZnxFe2O4 (0.0≤x≥1.0) spinel ferrite system synthesized by the sol–gel auto-combustion technique using nitrates of respective metal ions have been studied. The ratio of metal nitrates to citric acid was taken at 1:3. The as prepared powder of cobalt zinc ferrite was sintered at 600 °C for 12 h after TG/DTA thermal studies. Compositional stoichiometry was confirmed by energy dispersive analysis of the X-ray (EDAX) technique. Single phase cubic spinel structure of Co–Zn nanoparticles was confirmed by XRD data. The average crystallite size (t), lattice constant (a) and other structural parameters of zinc substituted cobalt ferrite nanoparticles were calculated from XRD followed by SEM and FTIR. It is observed that the sol–gel auto-combustion technique has many advantages for the synthesis of technologically applicable Co–Zn ferrite nanoparticles. The present investigation clearly shows the effect of the synthesis method and possible relation between magnetic properties and microstructure of the prepared samples. Increase in nonmagnetic Zn2+ content in cobalt ferrite nanoparticles is followed by decrease in nB, Ms and other magnetic parameters. Squareness ratio for the Co-ferrite was 1.096 at room temperature.


Solute-Solvent Interaction of Benzene with Acetic Acid at Different Temperatures.

Author - Siddarth P. Kamble, Y.S. Sudke, S.S. Patil, P.W. Khirade and S.C. Meharotra

Abstract - The present paper reports a study of binary mixtures of benzene and acetic acid over the entire range of composition at temperatures of 288, 298, 308 and 318 K. The measured values of static dielectric constant, density, and refractive index of the binary mixtures are further used to evaluate the excess dielectric constant, excess molar volume, excess refractive index, molar and excess molar refraction at these temperatures. The values of excess dielectric constant and excess refractive index are positive whereas the excess molar volume is negative over the entire range of mole fractions of acetic acid. The results are discussed in light of the intermolecular interactions occurring between the benzene and acetic acid molecules. The excess parameters were fitted with the Redlich–Kister equation and the resulting estimated Redlich–Kister coefficients (aj) and standard deviations are reported.


Dielectric characterization and molecular interaction behaviour in binary mixture of 1,2-diaminopropane with 2-aminoethanol

Author -   Undre P.B., Patil, S.S. , Khirade, P.W.

Abstract - The dielectric dispersion ε′ and dielectric loss ε″ of binary mixture of 1,2–diaminopropane – 2-aminoethanol were measured by employing the Time Domain Reflectometry technique over a frequency range 10 MHz to 20 GHz at 15, 25, 35 and 45°C. To evaluate various dielectric parameters, the frequency dependents complex permittivity (ε* (ω) = ε′- jε″) data such as static permittivity (εs), relaxation time (τ) and permittivity at high frequency (ε∞) were fitted by the non-linear least-squares fit method to Debye expression. Temperature dependent εs, τ, Kirkwood correlation factor (g), free energy of activation (ΔG) and enthalpy of activation (ΔH) have been determined and discussed in terms of the effect of -NH2 and -CH3 side-group on molecular dynamics and intermolecular hydrogen bonds. It is appropriate to report the present work on the dielectric behavior of 1,2–diaminopropane and 2-aminoethanol liquid molecules, and also their conformations, because the dielectric behavior and molecular dynamics of the system under study can be explored more clearly only by comparing the dielectric data of the mixture system with the dielectric data of the individual molecules and their dynamics.


Poly(o-toluidine) Nanowires Based Organic Field Effect Transistors: A Study on Influence of Anionic Size of Dopants and SWNTs as a Dopant.

Author -   Prasanta Ghosh, Kunal Datta, Ashok Mulchandani Sung-Hwan Han, Pankaj Koinkar and Mahendra D. Shirsat.

Abstract - Poly(o-toluidine) [P(OT)] nanowires electrode junction based organic field effect transistors (OFETs) with back-gated architecture are demonstrated. P(OT) nanowires have been site specifically synthesized to bridge Au micropatterns on Si/SiO2 substrate by facile galvanostatic route. Dopants with various sizes of anions have been employed during electrochemical synthesis of nanowires to study the possible impact of the same on electrochemical, morphological, spectroscopic, electrical, and FET characteristics. Observations show that varying the size of dopants significantly modulates crucial characteristic features of the FETs especially charge carrier mobility (μ) and on–off ratio (Ion/Ioff). A probable model of the observed behavior suggests the anionic size of the dopants to be a dominant factor in deciding the conduction behavior of the FETs, and such rationalization is supported by spectroscopic and electrical data obtained. The device fabricated with carboxylated SWNTs as dopant exhibited superior FET properties than its counterparts in terms of μ= 3.17 × 10–4 cm2 V–1 s–1 and Ion/Ioff = 1.85 × 104.


Porphyrins-Functionalized Single-Walled Carbon Nanotubes Chemiresistive Sensor Arrays for VOCs.

Author - Mahendra D. Shirsat,Tapan Sarkar, James Kakoullis Jr, Nosang V. Myung, BharatanKonnanath, Andreas Spanias and Ashok Mulchandani

Abstract - Single-walled carbon nanotubes (SWNTs) have been used extensively for sensor fabrication due to its high surface to volume ratio, nanosized structure and interesting electronic property. Lack of selectivity is a major limitation for SWNTs-based sensors. However, surface modification of SWNTs with a suitable molecular recognition system can enhance the sensitivity. On the other hand, porphyrins have been widely investigated as functional materials for chemical sensor fabrication due to their several unique and interesting physico-chemical properties. Structural differences between free-base and metal substituted porphyrins make them suitable for improving selectivity of sensors. However, their poor conductivity is an impediment in fabrication of prophyrin-based chemiresistor sensors. The present attempt is to resolve these issues by combining freebase- and metallo-porphyrins with SWNTs to fabricate SWNTs-porphyrin hybrid chemiresistor sensor arrays for monitoring volatile organic carbons (VOCs) in air. Differences in sensing performance were noticed for porphyrin with different functional group and with different central metal atom. The mechanistic study for acetone sensing was done using field-effect transistor (FET) measurements and revealed that the sensing mechanism of ruthenium octaethyl porphyrin hybrid device was governed by electrostatic gating effect, whereas iron tetraphenyl porphyrin hybrid device was governed by electrostatic gating and Schottky barrier modulation in combination. Further, the recorded electronic responses for all hybrid sensors were analyzed using a pattern-recognition analysis tool. The pattern-recognition analysis confirmed a definite pattern in response for different hybrid material and could efficiently differentiate analytes from one another. This discriminating capability of the hybrid nanosensor devices open up the possibilities for further development of highly dense nanosensor array with suitable porphyrin for E-nose application.

Author - S.B. Sayyad, P.B. Undre, P. Yannewar, S.S. Patil, P.W. Khirade, and S.C. Mehrotra

Abstract - Complex dielectric spectra ε*(ω) = ε‘ − j ε‘ ‘, in the frequency range 10 MHz to 10 GHz, have been determined using the time domain reflectometry (TDR) technique at various temperatures and different concentrations of alcohols, viz., ethanol, propan-1-ol, butan-1-ol, hexan-1-ol, and heptan-1-ol + aniline binary mixtures. The static dielectric constant (ε0) and relaxation time (τ) have been obtained. The values of ε0 and τ decrease with an increasing percent of aniline in the alcohol.

Author - B. N. Dole, V. D. Mote, V. R. Huse, Y. Purushotham, M. K. Lande, K. M. Jadhav and  S. S. Shah

Abstract - Mn substituted ZnO nanoparticles with compositional formula Zn1−xMnxO where x = 0.00, 0.04 and 0.08 were synthesized by sol-gel route. All the samples sintered at 650 °C for 12 h in a furnace followed by furnace cooling up to room temperature. X-ray diffraction (XRD) studies shows the presence of hexagonal crystal structure as same as parent compound (ZnO) in all samples. The lattice parameters ‘a’ and ‘c’ were determined from XRD data and found that they increase linearly with the Mn content, which suggests that doped Mn ions go to Zn sites. Grain size, X-ray density and Atomic packing fraction (APF) were evaluated using XRD data and found that grain size increases while X-ray density and Atomic packing fraction (APF) decreases with dopant concentration increases. The functional groups and chemical interactions of Mn substituted Zinc oxide samples were also determined at various peaks using FTIR data and observed the presence of function groups in the samples. Results of such an investigation presented in this paper.


Modified structural, surface morphological and optical studies of Li3+ swift heavy ion irradiation on zinc oxide nanoparticles.

Author - B. N. Dole H. A. Khawal, U. P. Gawai, K. Asokan

Abstract - Nanoparticles of ZnO were synthesized by a co-precipitation method. The ZnO samples were irradiated by Li3+ swift heavy ions (SHI) with fluences of 5 × 1011 and 1 × 1013 ions per cm2, constant current of 1 particle nano ampere (PNA) and Li3+ ion energy of 50 MeV. Structural parameters of pristine and SHI-irradiated ZnO nanoparticles were investigated by XRD. It was explicitly confirmed by XRD data that pristine and SHI-irradiated ZnO samples show wurtzite structures. The particle sizes of pristine and SHI-irradiated ZnO samples were estimated using XRD data and found to be in the range of 20 nm to 22 nm. SEM images show that the pristine sample has a spherical shape, whereas the ZnO sample SHI-irradiated with 5 × 1011 ions per cm2 fluence exhibits enlargement in grain size, and the sample irradiated with 1 × 1013 ions per cm2 fluence has a rod-like structure. EDAX was employed to investigate the elemental composition of the materials. Raman spectra show phonon interaction and vibration bands in the materials at 438.69 cm−1 and 435.95 cm−1 due to ZnO bonding. Atomic force microscopic (AFM) studies evince enhancement in roughness and track formations after SHI irradiation of ZnO samples as compared to the pristine counterpart. The UV-vis spectroscopy results show a decreased energy band gap (red shift) with enhanced Li3+ swift heavy ion irradiation on the ZnO nanoparticles.


Structural Studies on nanocrystallineZnS and CdS”

Author - S. Deshpande, K. Pandey, G. M. Dharne and S. Deshpande

Abstract - II-VI semiconductor nanocrystals have attracted much attention due to their size dependent properties ranging from electronic to biological regimes. Herein results of ZnS and CdS ADXRD (Angle dispersive X-ray diffraction) data, recorded in transmission mode, on BL-11 Beamline of INDUS Synchrotron are reported. Semiconductors obtained using wet chemical co-precipitation method, were kept for a few hours in the deep freezer. The wavelength of x-rays was 0.04666 nm (27 keV). A MAR 3450 image plate was used as detector. Sample to detector distance was 185.9178 mm. XRD data were extracted using fit2d. ADXRD pattern was recorded in transmission mode. The fityk program was used to fit pseudo Voigt A function to the ADXRD data to get the half width at half maximum (HWHM) of the peaks. These HWHMs values as well as the Scherrer formula yielded the particle sizes. The Neilson-Riley method was used to refine the lattice parameters. Results of the ADXRD data analyses for both ZnS and CdS are given below:The Particle size (nm), Bravais Lattice, Lattice parameter (nm) and Eg (eV) [UV abs spectra] for ZnS are 2.81, F43m, 0.5371 and 3.82 respectively while for CdS these values are 3.03, F43m, 0.580, 2.59 respectively. From these data the metal-S and Metal-Metal distances were calculated and were found out for ZnS to be 0.2326 nm and 0.3798 nm while for CdS these distances are 0.251 nm and 0.41 nm respectively. These data match well with the literature/1/. Particle sizes were in agreement with Brus's /2/ method.

Effective atomic number and electron density of amino acids within the energy range of 0.122–1.330 MeV

Author - Pravina P. Pawar  Chaitali V. More  Rajkumar M. Lokhande

Abstract - Photon attenuation coefficient calculation methods have been widely used to accurately study the properties of amino acids such as n-acetyl-l-tryptophan, n-acetyl-l-tyrosine, d-tryptophan, n-acetyl-l-glutamic acid, d-phenylalanine, and d-threonine. In this study, mass attenuation coefficients (µm) of these amino acids for 0.122-, 0.356-, 0.511-, 0.662-, 0.884-, 1.170, 1.275-, 1.330-MeV photons are determined using the radio-nuclides Co57, Ba133, Cs137, Na22, Mn54, and Co60. NaI (Tl) scintillation detection system was used to detect gamma rays with a resolution of 8.2% at 0.662 MeV. The calculated attenuation coefficient values were then used to determine total atomic cross sections (σt), molar extinction coefficients (ε), electronic cross sections (σe), effective atomic numbers (Zeff), and effective electron densities (Neff) of the amino acids. Theoretical values were calculated based on the XCOM data. Theoretical and experimental values are found to be in a good agreement (error<5%). The variations of µm, σt, ε, σe, Zeff, and Neff with energy are shown graphically. The values of µm, σt, ε, σe are higher at lower energies, and they decrease sharply as energy increases; by contrast, Zeff and Neff were found to be almost constant.
