In situ graphene hybridization is applied within the nanotube voids to reinforce carbon nanotube (CNT) networks, as demonstrated by X. M. Li, H. W. Zhu, Y. Fang, and co-workers on page 2078. The CNT–graphene hybrids effectively resist buckling deformation of the CNT network and load transfer within the hybridized film…
Friction properties being influenced by scale effects are simulated in the paper by the example of polymer composite material made from Ultra High-Molecular Weight Polyethylenes (UHMWPE) filled by calcium stearate (C 36 H 70 CaO 4 ). Of interest are the composites whose mechanical properties and tribotechnical charact…
Hexagonal phase NaYF4:Yb3+,Er3+ nanoclusters were prepared using a facile solvothermal method. The structures and morphologies of the products were investigated using an X-ray powder diffractometer and a transmission electron microscope. Modified by the capping agent of poly(acrylic acid), the as-prepared NaYF4 NCs sh…
En este trabajo se presenta un estudio sobre el comportamiento del campo de temperatura y del perfil de esfuerzos residuales que aparecen en una unin soldada tipo cruciforme durante la fase de enfriamiento postsoldadura. Se utiliza un modelo 3D y un anlisis de transferencia de calor transciente no lineal mediante el m…
Phase behavior of a neutral colloid dispersion is investigated based on an improved Asakura-Oosawa (AO) model. Several observations are made: (i) an increase of solvent fugacity can enlarge the fluid-solid (FS) coexistence region, and this makes fugacity become a powerful factor in tuning a vapor-liquid transition (VL…
Optical and electrical properties of 95% In2O3 + 5% SnO2/ns-Si heterostructures with films 6 and 12 nm in thickness deposited on a nanostructured silicon surface by the magnetron sputtering have been considered. It is shown that the 6-nm film is characterized by several peaks in the optical absorption spectrum, while…
1J50 alloy is one of the major iron–nickel compositions,well-known for high flux density, low coercivity and high saturation induction.In this study,the microstructure and magnetic domain struture of the soft magentic alloy 1J50 before and after heat treatment (HT) were studied using scanning electron microscopy (SEM)…
CoFe-LDH with broad interlayer space is strongly coupled with 2D graphene, leading to a novel composite with well interconnected conductive networks and enhanced mass and charge transfer ability. As reported by Jieshan Qiu, Chang Yu and co-workers in article number 1500782, this hydride material can deliver a low over…
In this study, to understand the effects of paramagnetic impurities, we investigated the temperature dependent of the spin-lattice relaxation times of pure LiNbO3, LiNbO3:Mg, LiNbO3:Mg/Ti, LiNbO3:Mg/Fe, and LiNbO3:Mg/Fe (thermally treated at 500°C) single crystals. The results for the LiNbO3:Mg single crystals doped w…
MnAlFe alloy was prepared by the combined use of smelting, high-energy ball milling and tempering heat treatment process. The phase composition and microwave absorbing properties of MnAlFe alloy were investigated by X-ray diffractometer(XRD) and vector network analyzer. The results show that the powders consist of Al8…

In this paper we study the morphology of drops formed on partially wetting substrates, whose footprint is not circular. These drops are consequence of the breakup processes occurring in thin films when anisotropic contact line motions take place. The anisotropy is basically due to the hysteresis of the contact angle s…
Mass transfer was examined at a stationary rectangular copper electrode (cathode) by using the reduction of cupric ions as the electrochemical reaction. The influence of electrolyte temperature (25, 45, and 65 oC), and cupric ions concentration (4, 8, and 12 mM) on mass transfer coefficient were investigated by using…
Nowadays, constant pressure on enviromental aspects in the foundry industry is calling for an improvement in casting production. The almost not used inorganic binders are coming back to the fore. Into this group, among others, belong binders based on alcali silicate solutions, known as water glass. The new hot-curing…
In this work, anthocyanin dye was extracted in ethanol from black rice and used as a sensitizer together with CdS and CdSe quantum dots (QDs) in a QD-dye-co-sensitized TiO 2 solar cell. QDs were prepared via wet solution processed method. Performances of the natural dye-sensitized solar cells with iodide based or coba…
We introduce a novel apparatus designed for stress-controlled rheometers to perform simultaneous rheological and electrical measurements on strongly conductive complex fluids under shear. By means of a non-toxic liquid metal at room temperature, the electrical connection to the rotating shaft is completed with minimal…
ABSTRAK Kerajinan kerang simping atau dalam bahasa latinnya Amusium pleuronectes banyak diminati oleh konsumen. Umumnya produknya berupa kap lampu yang dibuat dengan sistem bingkai menggunakan kuningan. Pada beberapa daerah kuningan sulit diperoleh, sehingga perlu dilakukan penelitian produk kerang dengan sistem bingk…
Dy1-x(Gd or Yb)xBa2Cu3O7-δsamples were prepared using chemical solution deposition, based on trifluoroacetate metal-organic decomposition methods. X-ray diffraction results demonstrated the formation of the RE123 superconducting phase with strong in-plane and out-of-plane texture. For all samples doped with Gd or Yb,…
Composite fibrous electrospun membranes based on poly(dl-lactide) (PLA) and poly(e-caprolactone) (PCL) were engineered to include borate bioactive glass (BBG) for the potential purposes of guided bone regeneration (GBR). The fibers were characterized using scanning and transmission electron microscopies, which respect…
Favimat single fibre tester is non-conventional textile testing equipment. Review of several Textile Testing textbooks revealed that neither any information nor mentioning of the equipment was provided even in the most recent publications. As a result, the mainstream force of textile professionals in most countries, i…
