Abstract The lattice dynamics in the IV–VI compounds GeTe, SnTe and PbTe were studied by 125 Te and 119 Sn nuclear inelastic scattering and the obtained partial density of phonon states were compared with published theoretical calculations. The phase purity and structure were characterized by high energy X‐ray diffrac…
In this study, we demonstrate that hydrothermal carbonization of low-cost wastes of willow bark leads to water-soluble, photoluminescent carbon dots (CDs) with diameters ranging from 1 to 4 nm and a quantum yield of approximately 6.0%. We further demonstrate the proof of concept that such CDs can be used as an effecti…
A structure prediction method for layered materials based on two-dimensional (2D) particle swarm optimization algorithm is developed. The relaxation of atoms in the perpendicular direction within a given range is allowed. Additional techniques including structural similarity determination, symmetry constraint enforcem…
Lithium salts have been shown to dramatically increase the conductivity in a broad range of polymeric and small molecule organic semiconductors (OSs). Here we demonstrate and identify the mechanism by which Li(+) p-dopes OSs in the presence of oxygen. After we established the lithium doping mechanism, we re-evaluate t…
Though building an AMESim physical model of vehicle three-way catalytic converter (TWC), this article aims to study the light-off characteristics of TWC. By solving the energy and mass conservation equations of gas-solid two phase of the model, this article obtains the emissions conversion rate, such as CO, unburned h…
The diffusion and conduction electrons in a bilayer graphene ribbon in an external electric field have been calculated. The Boltzmann kinetic equation in the semi-classical approximation of the relaxation time has been used. The analytical expressions for the diffusion of electrons and its nonlinear dependence on the…
We report on the synthesis and magnetic characterization of ultralong (1 cm) arrays of highly ordered coaxial nanowires with nickel cores and graphene stacking shells (also known as metal-filled carbon nanotubes). Carbon-containing nickel nanowires are first grown on a nanograted surface by magnetron sputtering. Then,…
This paper addresses the question to which extent anisotropic atomic motions in proteins impact angular-averaged incoherent neutron scattering intensities, which are typically recorded for powder samples. For this purpose, the relevant correlation functions are represented as multipole series in which each term corres…
Naturally available green spinach, which is a rich source of potassium, was used as the key ingredient to extract mixed-phase ferroelectric crystals of nitrite and nitrate derivatives (KNO2 + KNO3). The KNO3 phase was found to be dominant for higher pH values, as revealed by the x-ray diffraction patterns. The charact…
Benzotriazole-maleimide (BTM)-coated silver nanoparticles were synthesized through a simple one-pot route. The BTM linker serves as a bifunctional unit for the subsequent preparation of polymer–NP conjugates and the design of bio–Ag NP hybrids for further applications in biosensing platforms and material science.
We have presented the results of ab initio investigations on the structural, electronic and optical properties of MB 12 (M = Zr, Hf, Y, Lu) dodecaboride compounds. Especially, the lattice parameters, bond distances, bulk modulus, electronic band structure, density of state, optical properties and their related quantit…
We present the evolutionary algorithm that evolves the population of numerical solutions of the variational problem. The evolved solutions are model-independent, smooth, can have a predefined shape (if needed), and satisfy boundary or any other additional conditions (if imposed). To exemplify the performance of the pr…
Three new compounds, [MIMPS]5GeW11VO40, [MIMPS]5GeW10MoVO40, and [MIMPS]5GeMo11VO40, have been synthesized from 1-(3-sulfonic group) propyl-3-methyl imidazolium (MIMPS, C7H13N2O3) and germanium-containing heteropoly acids H5GeW11VO40, H5GeW10MoVO40, and H5GeMo11VO40. IR spectra indicate the formation of the hybrid mol…
Coatings are one of the most used protection methods for metals. Metallic coatings, such as zinc and its alloys, are used to protect steel in mild corrosive environments. In aggressive environments, on the other hand, organic coatings must be employed in the so-called duplex systems. However, the galvanized steel/orga…
A systematic approach was followed to develop a new hybrid organic–inorganic composite material with intriguing electrical and fluorescence properties into one ultrathin film system. Providing facile and cost-effective synthesis, this method utilizes a double decomposition reaction to introduce electric and fluorescen…
Tissue engineering research continues to captivate the interest of researchers and the general public alike. Popular media outlets like The New York Times, Time, and Wired continue to engage a wide audience and foster excitement for the field as regenerative medicine inches toward becoming a clinical reality. Putting…
We studied the structure and optical properties of B(4)C/Mo/Y/Si multilayer systems. Using extended x-ray absorption fine structure measurements at the Y and Mo K-edge, the structure of the subnanometer thick Y layer and the underlying Mo layer were analyzed. It was found that even a 0.2 nm thick Y layer significantly…
A process for the chemical modification of Chinese fir with alkyl ketene dimer (AKD) was studied. The hydrophobicity of the resulting products was evaluated by characterization of the equilibrium moisture content, water-surface contact angle, water absorption coefficient, and antiswelling efficiency. The results indic…
Recent experimental and theoretical investigations on asymmetric field emission induced by weak femtosecond laser pulses and also its emission mechanisms are briefly reviewed. The emission mechanisms are discussed further for a wider range of DC fields and laser power. It appears that firstly photo‐assisted field emis…
Abstract Biosolids from the Cañeveralejo WWTP were dehydrated by filter press and then applied two processes to reduce pathogens (PRP): thermally dried biosolid (TDB) and alkalinized biosolid (AB). Untreated, dehydrated biosolid (DB) was used as a control. We evaluated the impact of thermal drying and alkaline treatme…
