By the use of non-contact atomic force microscopy (NC-AFM) and Kelvin probe force microscopy (KPFM), we measure the local surface potential of mechanically exfoliated graphene on the prototypical insulating hydrophilic substrate of CaF 2 (111). Hydration layers confined between the graphene and the CaF 2 substrate, re…
ABSTRACT In this work we report the synthesis process and properties of PMMA‐ZrO 2 organic–inorganic hybrid films. The hybrid films were deposited by a modified sol‐gel process using zirconium propoxide (ZP) as the inorganic (zirconia) source, methyl methacrylate (MMA) as the organic source, and 3‐trimetoxy‐silyl‐prop…
Cadmium selenide (CdSe) and cadmium sulfoselenide (CdSxSe1−x) are important semiconductor materials for photovoltaic and other optoelectronic applications. Highly crystalline thin films of CdSe and CdSxSe1−x have been deposited on glass substrates by Aerosol Assisted Chemical Vapour Deposition (AACVD) from bis(diethyl…
The native cysteine (Cys)-Ag3 cluster hydrogel is approved for the first time by both experimental and theoretical studies. From the detailed molecular structure and energy information, three factors are found to ensure the self-assembly of Cys and Ag3 , and result in the hydrogel. First, the Ag-S bonds make Cys and A…
Ferroelectric materials are highly sensitive to grain size reduction because strain and ferroelectric polarization have a direct connection. Using 15 nm (Ba,Sr)TiO 3 particles obtained by advanced supercritical synthesis and their densification by high‐pressure spark plasma sintering under air, reproducible and dense…
A method of controlling the morphology of SnTe nanostructures produced by a simple chemical vapor deposition is presented, in which Au-containing catalysts with different Au concentrations are used to induce specific growth behavior. Triangular SnTe nanoplates with a {100} dominated surface and {100}, {111} and {120}…
A heat-sensitive layer (TiO 2− x ) was successfully deposited by RF reactive magnetron sputtering for infrared (IR) image sensors at different relative mass flow of oxygen gas ( R O2 ) levels. The deposition rate was decreased with an increase in the percentage of R O2 from 3.4% to 3.7%. TiO 2− x samples deposited at…
Abstract Energy storage devices, such as lithium‐ion batteries and supercapacitors, are required for the modern electronics. However, the intrinsic characteristics of low power densities in batteries and low energy densities in supercapacitors have limited their applications. How to simultaneously realize high energy…
The antimonate compound La3SbO7 has high chemical stability, lattice stiffness and thermal stability. Orange-red-emitting antimonate-based phosphors La3SbO7:xSm(3+) (x = 0.02, 0.05, 0.08, 0.10, 0.15, 0.20 and 0.25) were synthesized. The phase structure and photoluminescence properties of these phosphors were investiga…
In this article, a novel intumescent alumina–silica hydrogel double shell microencapsulated ammonium polyphosphate flame retardant is prepared and filled into polypropylene as a flame retardant. The structure and properties of alumina–silica hydrogel double shell microencapsulated ammonium polyphosphate are characteri…
Classical antibacterial surfaces usually involve antiadhesive and/or biocidal strategies. Glycosylated surfaces are usually used to prevent biofilm formation via antiadhesive mechanisms. We report here the first example of a glycosylated surface with biocidal properties created by the covalent grafting of sophorolipid…
Azobenzene linker molecules can be utilized to control peptide/protein function when they are ligated to appropriately spaced amino acid side chains of the peptide. This is because the photochemical E/Z isomerization of the azobenzene N=N double bond allows to switch peptide conformation between folded and unfolded. I…
Na8Al6Si6O24(Cl,S)2 materials were prepared with a solid state reaction. The products were studied using X-ray powder diffraction, reflectance measurements as well as X-ray fluorescence, conventional and persistent luminescence, nuclear magnetic resonance, and electron paramagnetic resonance spectroscopies. All materi…
The corrosion inhibition behavior of Ketosulfone for zinc is investigated by polarization and AC-impedance techniques at 303-333K. The Tafel plots indicates that the Ketosulfone is a mixed type inhibitor. The interaction between metal and inhibitor is explained by Langmuir adsorption isotherm. DG0ads andDH0ads value i…
One-dimensional (1D) and two-dimensional (2D) titania/titanate nanostructures are fabricated directly on a self-source metallic titanium (Ti) surface via in situ surface re-construction of a Ti substrate using potassium hydroxide (KOH) under a hydrothermal (HT) condition. The effect of temperature and the concentratio…
CdTe quantum dots (QDs) capped with different stabilizers, i.e. thioglycolic acid (TGA), 3-mercaptopropionic acid (MPA) and glutathione (GSH) were investigated as fluorescent probes for the determination of Cu(2+). The stabilizer was shown to play an important role in both the sensitivity and selectivity for the deter…
This article contains a critical review of the literature concerning the information depth of electron backscatter diffraction (EBSD) and a viewpoint on the topic is formulated. EBSD is applied to a crystal partially covered by a wedge of amorphous glass. EBSD-patterns of decreasing quality are obtained from a crystal…
A one-dimensional continuum endowed with internal structure, previously introduced by the authors, is extended and generalized by giving a procedure for constructing the constitutive functions. Starting from the reference configuration of a carbon nano sheet (CNS), a representative elementary volume (REV) is chosen. T…
The unique mechanical performance of nacre, the pearly internal layer of shells, is highly dependent on its complex morphology. Inspired by the structure of nacre, the fabrication of well-ordered layered inorganic-organic nanohybrids is presented herein. This biomimetic approach includes the use of a block copolymer t…
In this study, tribological investigations were carried out on ZTA ceramics with 17 vol% Y‐TZP and different stabilizer contents (1, 1.5, and 2 mol% yttria) to analyze the influence of zirconia transformation on wear properties. Samples were tested in a linearly reciprocating ball on flat setup with different applied…
