Gaseous titanium hydroxide and oxyhydroxide species were studied with quantum chemical methods. The results are used in conjunction with an experimental transpiration study of titanium dioxide (TiO 2 ) in water vapor-containing environments at elevated temperatures to provide a thermodynamic description of the Ti(OH)…
Abstract The fuel cell system is modeled to investigate output factors including voltage, power, and system efficiency for various input elements including different fuel composition, the air and fuel temperature and their utilization ratios. The purpose of this study is to examine the proficiency of a tubular solid o…

An experimental investigation of spontaneous emulsification is proposed with a water drop pendant in a paraffin oil (PO) solution loaded with a surfactant (SPAN80). Optical microscopy in a transmission mode is employed for high-spatial-resolution image recording. The kinetics of spontaneous emulsification is studied.…
The adsorption of NO on cationic Rh clusters, Rh n + ( n = 6–16), was studied by IRMPD spectroscopy using FELIX in combination with DFT calculations. The IRMPD spectra show that NO adsorbs molecularly on an on-top site of Rh n + for all n studied, while for n = 7, 12, 13, and 14 evidence is found for a second, bridgin…
Europium doped Y 2 O 3 nanophosphors have been prepared by the solution combustion method. The prepared nanophosphors were characterized by powder x-ray diffraction (XRD). XRD revealed that the cubic phase with crystallite size in the range 25–37 nm formed. Surface morphology of the samples was studied by field emissi…
The lattice oxygen in PGM/Sr <sub>3</sub> Fe <sub>2</sub> O <sub>7−δ</sub> contributes to the oxidation of CO and C <sub>3</sub> H <sub>6</sub> and the oxygen vacancy sites can play a role in NO reduction.
Two conjugated polymers (CPs) with various compositions of phenylene and benzoselenadiazoben (BSD) are synthesized to have a special emitting property; different fluorescence colors in solution and in the solid states, allowing the resulting conjugated polymer dots (Pdots) to emit different fluorescence colors upon th…
In the presence of a midblock-selective solvent, triblock copolymers not only self-organize but also form a molecular network. Thermoplastic elastomer gels constitute examples of such materials and serve as sealants and adhesives, as well as ballistic, microfluidic, and electroactive media. We perform Monte Carlo and…

While there is great interest in understanding the fate and transport of nanomaterials in the environment and in biological systems, the detection of nanomaterials in complex matrices by fluorescence methods is complicated by photodegradation, blinking, and the presence of natural organic material and other fluorescen…
Electromagnetic metamaterials offer great flexibility for wave manipulation and enable exceptional functionality design, ranging from negative refraction, anomalous reflection, super-resolution imaging, transformation optics to cloaking, etc. However, demonstration of metamaterials with unprecedented functionalities i…
This paper compares the impact of laser treatment on cotton and cotton/polyester blended fabric hand properties, using the PhabrOmeter system. Five fabric hand properties, namely, stiffness, smoothness, softness, wrinkle recovery rate, and drapability, were obtained, and it was proven that laser treatment could be suc…
Selective catalytic reduction technology was considered to be the most effective technology for NO x treatment, and Mn 2 O 3 had good catalytic activity. In this paper, we successfully synthesized α -Mn 2 O 3 and γ -Mn 2 O 3 nanorods by hydrothermal method. Moreover, in order to study the effects of surface physicoche…
In this paper a rigorous mathematical approach to the near-field diffraction of 1D periodic structures at quarter-Talbot distances is presented. At the beginning of the paper, we present a mathematical investigation on the behavior of periodic functions under squaring by the aid of Fourier analysis. We determine suffi…
Elastocaloric cooling demands for temperature changes larger than 30 K to become an alternative to classical vapour compression cooling systems. The principle of active regeneration allows to exceed the materials intrinsic adiabatic temperature change. The resulting temperature gradient of the cooling demonstrator lea…
In this work, carbon papers and aerogels based on graphene layers and chitosan were prepared. They were obtained by mixing chitosan (CS) and a high surface area nanosized graphite (HSAG) in water in the presence of acetic acid. HSAG/CS water dispersions were stable for months. High resolution transmission electron mic…
Scanning electron microscopy (SEM) is widely used to observe graphene on metal substrates. However, the origin of the SEM image contrast of graphene is not well understood. In this work, we performed in situ SEM imaging of layer-number-controlled graphene on a Ni substrate using a high-pass energy filter for secondary…
Enzymes are biopolymeric complexes that catalyse biochemical reactions and shape metabolic pathways. Enzymes usually work with small molecule cofactors that actively participate in reaction mechanisms and complex, usually globular, polymeric structures capable of specific substrate binding, encapsulation and orientati…
Two types of GaN based photoelectrodes using either horizontally aligned or vertically aligned nanopores have been fabricated by means of using an electrochemical etching approach. The photoelectrodes based on such nanostructures have demonstrated an up to 5-fold enhancement in applied bias photon-to-current efficienc…
