Compositional variation of the band gap energy and refractive index of TlMeX2-type (Me = Ga or In and X = S or Se) layered mixed crystals have been studied by the transmission and reflection measurements in the wavelength range of 400–1100 nm. The analysis of absorption data of TlGa1-xInxSe2, TlGa(S1−xSex)2, TlGa1−xIn…
The performance of near-surface disposal facilities (NSDFs) for low-level radioactive waste depends on the type of materials used in the construction of barrier system, the properties of geological formations around the facility, and the type of waste containment system. By taking into account the effect of the factor…
Abstract Attachment of bulky substituents at both thiophene donor (D) and thiazole acceptor (A) heterocycles of a dipolar (μg=10.4 D) D‐π‐A merocyanine dye affords a more than 1 Å expansion of the common antiparallel supramolecular dimer motif in the solid state, enabling very close π‐contacts (3.36 Å) to two other ne…
Abstract Lowering the activation energy of a chemical reaction is an essential part in controlling chemical reactions. By attaching a single electron, a barrierless path for the cis–trans isomerization of maleonitrile on the anionic surface is formed. The anionic activation can be applied in both reaction directions,…
Single crystal growth of γ-glycine has been grown by solution growth technique. The lattice parameters and crystal system of the grown crystals were confirmed by single crystal X-ray diffraction analysis. The functional groups present in the grown crystal were identified by FT-IR spectral analysis. The optical propert…
Cellulose was used as a base polymer in two prepared resins when it was grafted by glycidyl methacrylate (GMA) then immobilized with 8-hydroxyquinoline by two different procedures. The resulting resins were characterized by infrared (IR) spectroscopy, thermogravimetric analysis (TGA), and nitrogen surface area measure…
We demonstrate that an adsorption potential at the gate adsorption pressure of soft porous crystals (SPCs) based on the Polanyi's potential theory of adsorption shows a constancy to temperature. This was done using grand canonical Monte Carlo simulations and free energy analysis, which were carried out with a simplifi…
Nanoparticles (NPs) are included in a variety of consumer products including cosmetics, food, and food packaging. They are also used in medical products for dermal and oral application and for inhalation. The thinness of the air–blood barrier, the large absorption area of the lung, and the relatively low inactivation…
This paper reports on an experimental and analytical investigation conducted into efficacy of the scraping shear-test method in estimating the shearing adhesive strength of a thermally sprayed coating. It was found that the critical average shear stress, the apparent failure strength of WC-Co thermal spray coating, de…
Utilizing wood powder and corn starch as the main materials with polyurethane adhesive as a cross-linking agent, the starch/wood powder composite material was prepared via molding forming techniques. The effects of wood powder mesh and addition of wood powder on the properties of composite material were investigated.…
Anion receptors based on a [CpFe(indenyl)] scaffold offer the possibility for the incorporation of adjacent Lewis acidic functions onto a six-membered carbocyclic framework, while at the same time retaining the colorimetric/electrochemical reporter mechanisms available to synthetically simpler ferrocene systems. Thus,…
In this study, the effect of pH values on the microstructure and photocatalytic activity of Ce-Bi2 O3 under visible light irradiation was investigated in detail. In alkaline condition (e.g. pH = 9), the as-prepared Ce-Bi2 O3 exhibited an agglomerated status and mesoporous structures without a long-range order. While i…
Machining, in general, and wood machining, in particular, is a complex to explain and describe many influencing factors. Natural wood is nonhomogeneous biological material, so each species of wood requires different machining conditions and tools. Understanding of wood properties, proper selection of cutting tools and…
Graphene is considered today the most amazing and versatile substance available to mankind, and since its discovery in 2004, it is without any doubt the most intensively studied material [1,2]. From a chemical point of view, it is constituted by a single atomic layer of sp2-hybridized carbon atoms, with a molecule bon…
We theoretically study the transmission reduction of light passing through absorptive molecules embedded in a periodic metal slot array in a near infrared wavelength regime. From the analytically solved transmitted light, we present a simple relation given by the attenuation length of light at the resonance wavelength…
The rolling process is widely used in the metal forming industry and has been so for many years. However, the process has attracted renewed interest as it recently has been adapted to very small scales where conventional plasticity theory cannot accurately predict the material response. It is well-established that gra…
Bleaching clay refers to clays that in their natural or activated state have the capacity to absorb dyes and other remaining undesirable ingredients from edible oil during its purification processes. Thus, the most important function of bleaching clay is to improve the appearance, flavor, odor, and stability of the fi…
A technique to determine the permeability from X-ray microtomographic images was developed and applied to paper structures. The images are thresholded and a skeleton of the pore space is obtained from the images. The skeleton is represented by means of a network of resistances. The total resistance of the network alon…
Fabrication of Solid Oxide Fuel Cells (SOFCs) electrolytes by Electrophoretic Deposition (EPD) was the target of our study. For such purpose, thin layers of Yttria Stabilized Zirconia (YSZ) were electrophoritically deposited on pre-sintered NiO-YSZ pellets. A thin graphite film on each pellet was painted to make it co…
Nanocomposite hydrogels were prepared through a blend solution of poly(lactic acid) and poly(N-isopropylacrylamide)-co-acrylamide via free radical polymerization. Plant extractions were used for the synthesis of Ag nanoparticles to study the antibacterial activity of the hydrogels. Similarly, 5-Fluorouracil drug was l…
