The influence of phosphate of aluminum (PA) on the corrosion inhibition of mild steel in phosphoric acid solution was studied using the weight-loss method. The electrochemical performance of the inhibitors was also investigated through potentiodynamic polarisation and EIS measurements. The inhibition efficiency of inh…
In this study, our goal is to obtain lower density of ethylene-vinyl acetate copolymer (EVA)/ethylene-1-butene copolymer (EtBC) foams without sacrificing mechanical properties. For this purpose EVA/EtBC/organoclay (Cloisite 15A, Closite 30B) nanocomposite foams were prepared. To investigate the effect of compatibilize…
The substitution of cobalt and nickel for manganese in the perovskite manganate LaBiMn2O6+δ has been realized, leading to the perovskites LaBiMn2−MxO6+δ, with M = Co, Ni and 0 ≤ x ≤ 2/3. In contrast to the literature these phases are found to be orthorhombic with Pnma symmetry. More importantly, it is shown that ferro…
In this article a method is presented to prepare MCC from cellulose pulp employing an environment-friendly, effective two-step radiation-enzymatic depolymerisation process. The process was grounded on the radiation degradation by means of an electron beam to initially depolymerise the pulp prior to enzymatic hydrolysi…
Since Sumio Iijima identified the hollow Carbon Nanotubes (CNTs) in the early 1990s, there have been significant research efforts to synthesise inorganic nanotubes of various solids. Generally, the formation of tubular nanostructures requires layered, anisotropic, or pseudo-layered crystal structures. Inorganic nanotu…
We have established a fabrication process for conductive carbon nanotube (CNT) tips for multiprobe scanning tunneling microscope (STM) with high yield. This was achieved, first, by attaching a CNT at the apex of a supporting W tip by a dielectrophoresis method, second, by reinforcing the adhesion between the CNT and t…
We have developed a numerical model to simulate the hydrogen desorption profiles for pure iron and eutectoid steel, which is obtained in thermal desorption analysis (TDA). Our model incorporates the equation of McNabb and Foster without the hydrogen diffusion term combined with the Oriani's local equilibrium theory. I…
We describe the integration of optically pumped silicon nanocrystals (Si-ncs) embedded in SiO(2) with low loss silicon nitride slab waveguides. An emission waveguide containing Si-ncs with a broad band emission centered at 850 nm, together with a low loss transmission silicon nitride waveguide forms a two section devi…
Abstract Ion-based organic dye nanoparticles ranging from tens to hundreds of nanometers have been prepared in aqueous solution. The synthetic approach is based on “ion-association” (hydrophobic ion-pair formation) in water between the dye cation pseudoisocyanine (PIC) and the anion tetraphenylborate (TPB) or tetrakis…
This work has investigated luminescence properties of SrSi2O2N2: Eu2+ phosphors synthesized by a new method using Sr2SiO4: Eu2+ as a precursor. Compared with a conventional solid-state reaction method, this method provides increased crystallinity and luminescence efficiency. X-ray diffraction analysis has indicated th…
Recent results on the photoluminescence properties of silicon nanocrystals embedded in silicon oxide are reviewed and discussed. The attention is focused on Si nanocrystals produced by high-temperature annealing of silicon rich oxide layers deposited by plasma-enhanced chemical vapor deposition. The influence of depos…
A novel hierarchical porous material was synthesized via hydrothermal growth of faujasite on the surface of diatomite frustules previously seeded with nano-zeolite crystals. The material was successfully tested for the removal of cobalt from aqueous solutions and its subsequent vitrification proved to be a practical w…
An isothermal section of the partial Ag–In–Yb phase diagram, involving the icosahedral quasicrystalline (i-QC) phase and its corresponding 2/1 and 1/1 approximants (AP) at 823 K, has been determined. The i-QC, 2/1 and 1/1 AP exist in the compositional region around Ag42In42Yb16, Ag41In44Yb15 and Ag40In46Yb14, respecti…
The diversity and ubiquity of plastic products substantially testify to the versatility of the special class of engineering materials known as polymers. However, the non-biodegradability of these petrochemical-based materials has been a source of environmental concerns and hence, the driving force in the search for gr…
For CaO–CaF2–SiO2 and CaO–CaF2–Na2O–SiO2 systems, the effect of Na and Ca cation ions on the polymerization of silicate slags containing F ions and their structures are investigated by using molecular dynamics simulation. The substitution of F for O in the CaO–SiO2 melts enhances the polymerization of the melt due to…
Data mining has been successfully applied in many fields. However, little research has been done in the area of developing female size charts for consumer garment design. Focusing on the anthropometric data of adult females in Taiwan, the goal of this study was to develop garment-size charts, using a cluster-based dat…
The electrical conductivity of double-walled carbon nanotubes of the “armchair” type with the ABAB packing of layers is investigated theoretically. The temperature dependences of the longitudinal electrical conductivity σ( T ) for a number of double-walled carbon nanotubes, such as the (3, 3)@(8, 8), (5, 5)@(10, 10),…
α - Fe nanorods encapsulated in multiwall carbon nanotubes (CNTs) were characterized by x-ray diffraction (XRD), high resolution electron microscopy (HREM), and electron holography. HREM observations revealed that the α-Fe nanoparticles were single crystals with a preferential growth direction of ⟨200⟩α-Fe oriented al…
The use of holographic structures is promising for the realization of efficient systems in backlight applications for displays. By applying surface relief gratings on top of a side-lit lightguide we realize a backlight that avoids the use of color filters. The grating is used as a light outcoupling and color-separatin…
P-type Bi0.4Sb1.6Te3 thermoelectric materials were prepared by an angular extrusion technique with rapidly solidified and stacked foils in a temperature range from 643 K to 838 K. Textures of the angular-extruded specimens were observed by Orientation Imaging Microscopy (OIM). The average grain size was monotonously e…
