Fabrication of free-standing/highly conducting ultrananocrystalline diamond (fc-UNCD) films at low growth temperature (<475 °C) is demonstrated. The fc-UNCD films show high conductivity of σ = 146 (Ω cm)−1 with superior electron field emission (EFE) properties, viz. low turn-on field of 4.35 V/μm and high EFE c…
The temperature dependences of the lattice parameters and residual stress have been measured for a fine-grained Ni52.2Mn26.8Ga21.0 (at. %) thin film fabricated by sputter deposition onto a heated silicon wafer with SiNx buffer layer. The transformation volume strain in the film was found to be a lattice expansion duri…
We demonstrated a way to fabricate the crystalline Ba0.6Sr0.4TiO3 (BST) thin films using excimer laser annealing technique on the amorphous BST thin films fabricated by sol-gel process. The grain size of the laser-annealed films is larger than that of the conventionally thermal-annealed films. However, an uncrystalliz…
ABSTRACT Electrospinning has been recognized as a feasible process for fabrication of continuous fibers with diameters ranging from several micrometers to a few nanometers. In the present study, electrospinning of acrylonitrile (AN) and methyl methacrylate (MMA) copolymer in tetrahydrofuran (THF) solvent has been inve…
The solubility of α-calcium sulfate hemihydrate in CaCl 2 –MgCl 2 –KCl solution at temperatures from (353.0 to 371.0) K was measured by the dissolution equilibrium method. The investigated concentration ranges of CaCl 2, MgCl 2, and KCl were up to (6.01, 4.50, and 0.27) m, respectively. The calcium ion demonstrates th…
The atomic layer deposition (ALD) of ZnS films with Zn(TMHD)2 and in situ generated H2S as precursors was investigated, over a temperature range of 150–375 °C. ALD behavior was confirmed by investigation of growth behavior and saturation curves. The properties of the films were studied with atomic force microscopy, sc…
Aluminum fluoride (AlF(3)) is a low-refractive-index material widely used in coatings for deep-ultraviolet (DUV) optical systems, especially 193 nm laser systems. Low optical loss and stability are essential for film application. In this study, AlF(3)> thin films were prepared by thermal evaporation with a resistive h…
We describe the synthesis, crystal structures, electronic absorption spectra, and electrochemistry of a series of square-planar nickel-bis(quinoxaline-6,7-dithiolate) complexes with the general formula [Bu(4)N](2)[Ni(X(2)6,7-qdt)(2)], where X = H (1a), Ph (2a), Cl (3), and Me (4). The solution and solid-state electron…
Nanowire arrays have typical distributions of coercive and interaction fields, as revealed in experiments by means of the first-order reversal curve (FORC) method. In an axial applied field, each nanowire is subjected to a state dependent interaction field created by all wires from the array, which strongly influences…
Abstract Epoxy/anhydride networks were modified, in the presence of benzyldimethylamine as catalyst, with two polyhedral oligomeric silsesquioxanes (POSS), whose inorganic framework had a compact and stable Si‐O core and an organic substituent shell. The influence of the content and type of POSS during curing and on t…
ABSTRACT This article reports the first oil‐absorbent cross‐linked copolymer consisting of modified multiwalled carbon nanotube (MWCNT) and showing high oil absorbency. Also, to investigate and evaluate the effective parameters on oil absorbency, cross‐linked dodecyl methacrylate (DDMA)–diphenylacrylamide (DPAA) and D…
We report on the properties of metal-semiconductor-field-effect-transistors (MESFETs) on ZnO films grown using the filtered cathodic vacuum arc (FCVA) technique. FCVA ZnO films deposited on a-plane sapphire at 200 °C showed good structural and electrical properties that improved further on annealing at 800 °C in oxyge…
We have successfully prepared unique inorganic-organic hybrid materials that demonstrate excellent transparency and dewettability toward various alkane liquids (n-hexadecane, n-dodecane and n-decane) without relying on conventional surface roughening and perfluorination. Such coatings were made using a novel family of…
The sulfur-transfer catalyst is widely used to remove the sulfur oxides (SO x ) from the flue gas in the fluid catalytic cracking (FCC) units. This paper reports the influence of the pore structure of the Ce/MgAl hydrotalcite-derived mixed oxides on its SO x pick-up capacity. The Ce/MgAl hydrotalcites precursors were…
The charge confinement in silicon nanocrystals over the temperature range 35–300 K was investigated by complex impedance spectroscopy (CIS). A charge response found in the “dark” (i.e., no laser pumping) CIS spectrum indicated a frequency shift with temperature, which was well correlated with the temperature dependent…
The development of drug delivery systems in experimental therapy usually requires in vitro release models, that should posses specific characteristics including: low cost, simple procedure, high reproducibility and very importantly resemble as strictly as possible the in vivo behaviour. In this respect, the paper desc…
In this study, various alkyl 3,4-ethylenedioxythiophene derivatives (methyl to dodecyl) were used as monomers for the electrodeposition of conducting polymer films from hydrophilic to superhydrophobic. For a deposition charge of 100 mC/cm 2 , the study of their surface wettability reveals that superhydrophobic propert…
For some specific biomedical applications, connected with in-situ measurements of the absorbed dose of ultraviolet (UV) light, we have developed materials, sensitive to the light emission with a wavelength up to 320nm. Thermoluminescence (TL) yield of Gd 2 O 3 , doped with Eu and Li has been analysed with respect to t…
Single-crystal strontium titanate (SrTiO3) dense spheres have been synthesized via a solvothermal reaction route with monoethanolamine as reaction medium solvent. The as-synthesized SrTiO3 products were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, high-resolution…
We reported a highly efficient and low-cost way to synthesize silver nanosphere dimers on a poly(dimethylsiloxane) (PDMS) sheet by using a stepwise upright assembly method for the “hot spots” study of surface-enhanced Raman scattering (SERS). The first silver nanoparticle (NP) layer is almost entirely embedded in PDMS…
