One-dimensional Co3O4 nanotubes were grown in alignment on the surface of micron-sized Co3O4 hexagonal-box via a mild template-free wet chemical method. The nanotubes are ∼250 nm in diameter with several micrometers in length. The growth mechanism and phase formation for the vertically grown nanotubes on the surface o…
Single-walled carbon nanotubes were dispersed in deionized water with sodium dodecyl benzene sulfonate as surfactant. The solutions were sprayed on UV and plasma treated polyethylene terephthalate to achieve transparent conductive films with excellent adhesion. The carbon nanotube films were further treated with diffe…
We have grown graphene directly on alumina (Al2O3) substrates without catalysts using conventional thermal chemical vapor deposition. By choosing Al2O3 as a growth substrate, the polycrystallinity of graphene was enhanced to form nanometer-size dome-like grains, which ensured a statistically homogeneous electrical pro…
Phosphorus resources are limited in the world and there have been some alarming reports that deposits of high-grade phosphate ores are likely to be depleted in the next few decades. Layered double hydroxides (LDHs), known as hydrotalcite-like compound or anionic clays, have drawn much attention on their high adsorptio…
A free-standing fluorescent gelatin-Si nanoparticle composite thin film is facilely prepared by means of a filtration technique assisted by porous copper hydroxide nanostrands as a sacrificial layer. The as-prepared gelatin-Si nanoparticle composite film is greatly portable, flexible, transparent and free-standing. Th…
Developing a new type of automobile engine fuel injection system with a smart actuator instead of traditional serve valve controlling is the key source for the engine’s fuel-saving and emission reduction. It is critical to solve the environmental protection and energy conservation issues of automobile industry. In thi…
A novel method for the in situ generation of catalytically active small metal nanoparticles, by anion extrusion on a parent porous copper chloropyrophosphate framework, has been developed to generate gold, platinum and palladium nanoparticles for sustainable catalytic oxidations using molecular oxygen as the oxidant.…
An experimental and computational method of constructing true strain diagrams of steel tubular specimens under tension to rupture at large deformations is developed. Experimental and theoretical studies were performed to investigate the effect of the geometric parameters of cylindrical shells, initial imperfections of…
Cuprous oxide (Cu 2 O) films were prepared on an indium tin oxide glass substrate by radiofrequency magnetron sputtering using a high‐purity Cu target. The temperature of annealing was varied to obtain Cu 2 O thin films with various elements, compositions, and surface structures. The p‐Cu 2 O thin films thus formed we…
Surface morphology of materials brings various new properties to the surface, and thus, the control of the surface morphology is very important. In this paper, surface morphology control of sol–gel derived films using several processes has been reviewed. Hot water treatment (bottom up process), combination of UV-irrad…
We report on an emergent coherent behavior of a ferromagnetic colloidal monolayer suspended at a liquid–air interface and powered by a single-axis alternating in-plane magnetic field. Large-scale coherent states are manifested by formation of dynamic vortex arrays within the colloidal monolayer. Emergence of the dynam…
Molecular modeling as a tool in studying peptide-substrate interactions provides insight on peptide adsorption conformation, adsorption energy, and stability of the peptide-inorganic interface. This work investigates the hydration and interaction of cell-adhesion peptides, specifically RGD and YIGSR, with the hydroxya…
In this work, the effect of barium zirconate titanate (BZT) particle size on the dielectric properties and hysteresis behavior of 0-3 Barium zirconate titanate- Portland cement composites was investigated. BZT of various particle sizes (75, 212 and 425 μm) were used at 50% by volume to produce the 0-3 lead-free compos…
In this study, design experimental by two-level Factorial design to screen the factors to those factors that affect the ablation rate significantly. The following parameters were varied: amount of phenolic curing temperature and curing time. Factors that affect the ablation rate are as follows curing time, amount of p…
Porous materials allow for easier osseointegration of implants and their firmer connection with the bone. The presence of pores in a material may become a source of both mechanical and corrosion problems. The presented study explored a Ti-39Nb alloy with a porosity of 0-33%. Specimens were exposed in the physiological…
Polymer-derived ceramics (PDCs) represent a rather novel class of ceramics which can be synthesized via cross-linking and pyrolysis of suitable polymeric precursors. In the last decades, PDCs have been attaining increased attention due to their outstanding ultrahigh-temperature properties, such as stability with respe…
This work uses a finite element modeling method to study the electromechanical coupling factor of piezoelectric materials. Two types of piezoelectric materials were chosen, piezoelectric materials (PZT) and Pb-free piezoelectric materials Ba(Zr0.2Ti0.8)O3-50(Ba 0.7Ca 0.3)TiO3 (BZT -50BCT) that measure the resonance an…
Diatoms are unicellular algae, which due to their importance for the global primary production and their cellular and genetic complexity, became popular subjects of physiological and molecular biological research in the recent years. The increasing genomic information gathered on diatoms since the last decade promotes…
PLA-hemp-nanosilica composites were prepared by a film stacking method, using hot compaction in a heated press with interspersed layers of hemp fibre. Dynamic mechanical properties measured with modulated force thermomechanometry (mf-TM) showed that the storage modulus increased with increase in filler loading due to…
The effect of Co addition, as an alloying element, on the microstructure and corrosion behavior of Ni52Ti48-xCox (x = 0, 0.5, 1.5, and 4.0%) shape memory alloys (SMAs) was studied. The microstructure of Ni52Ti48-xCox SMAs consisted of B2 austenite phase as the matrix, and small percentages of B19' martensite phase. In…
