The surface chemistry of different plasma-treated PEEK was characterized by contact angle measurements and X-ray photoelectron spectroscopy and the results of the different methods were compared. In addition, the physicochemical changes on the surface were documented and evaluated within the course of the aging/recove…
The synthesis of previously unknown esters of 4-(arylmethylene)-5-oxo-4,5-dihydroisoxazole-3-carboxylic acids from aromatic aldehydes, hydroxylamine-O-sulfonic acid and diethyl acetylenedicarboxylate via a two-step one-pot reaction is presented. The mechanism of the reaction is discussed, and optimization is carried o…
Electroabsorption in metallic nanoparticles within transparent dielectric media has been measured. In particular, gold nanoparticles in glass and subnanometer-size metallic domains in iodine doped nonconjugated conductive polymer have been studied. Measurements have been made for applied ac fields at 4 kHz, at a wavel…
Cerium (Ce) doped ZnO is a promising material for advanced photocatalysis. It is useful for inducing the treatment of many organic pollutants in water. However, the stability of its performance under varying temperature and saline condition has never been not fully assessed. In this study, powder form photocatalyst co…
Polymers are used as food packaging material to preserve the food and to increase the shelf life. Oxygen accelerates the growth of bacteria and other microorganisms and can reduce the durability of the food. By using polymers as a food packaging material, the decomposition and the amount of food waste can be reduced.…
Silica borotellurite glasses doped with different molar fraction of V2O5 have been prepared by melt quenching technique. The elastic properties of {[(TeO2)0.7 (B2O3)0.3]0.8(SiO2)0.2}(1-x)(V2O5)x glasses are investigated using ultrasonic pulse echo measurements and their elastic properties have been characterized at ro…
SiO2/ZrO2 and SiO2/ZrO2/Al2O3 composite organic–inorganic coatings were prepared by the sol-gel technology. The structure of the coating was characterized by IR, particle size analyzer, SEM, and AFM, respectively. The results showed that ZrO2, SiO2 (inorganic component), and siloxane had undergone a hydrolytic condens…
Abstract Solution–solid–solid (SSS) nanowires can be catalyzed by superionic Ag2S via ion diffusion. Here, we synthesize ZnS nanowires of the wurtzite crystal structure and heterostructures via a low-temperature growth pathway. Single-crystalline ZnS nanowires were produced by varying reaction time and temperature (12…
Three new cyclometalated iridium(III) complexes [(cf3piq)2Ir(N∧N)][PF6] (Ir1–Ir3) have been synthesized and characterized. The solid structure of Ir1 has been determined by X-ray crystallography. The structure–property relationships of these complexes have been discussed by spectroscopic, computational, and electroche…
Cyclic voltammetry can be used to investigate the chemical reactivity of species ion via oxidation and reduction process. The purpose of this study is to determine the level energy of high occupied molecule orbital (HOMO) and low unoccupied molecule orbital (LUMO) in polythiophene (PT), Poly (3-thiophene acetic acid)…
Abstract MnO 2 -doped lead-free ceramics 0.91K 0.45 Li 0.05 Na 0.5 NbO 3 -0.08BaZrO 3 -0.01Bi 0.5 Na 0.5 TiO 3 (KNLN-BZ-BNT-Mn) were prepared by conventional solid-state reaction method. Dielectric and piezoelectric properties of the ceramics with different amount of MnO 2 were studied. The experimental results showed…
Biofouling and biofilms exist as ubiquitous, undesirable accumulation of flora and fauna upon a given substrate when being immersed into an aquatic medium. Therefore, a novel antifouling based materials with the incorporation of nanotechnology has been developed for the prevention of biofouling in its initial stage th…
Because electromagnetic (EM) pollution of the environment is becoming such a pervasive issue, highly efficient solutions for EM protection are being keenly sought for. Our approach provides new avenues to simple, compact, and efficient broadband microwave absorbers designed to cancel EM interferences in the microwave…
Here we present the synthesis and redox properties of a selection of boron subphthalocyanine dimers that are either connected by an oligoyne bridge via the axial boron atoms or via peripheral positions on the cyclic cores. The compounds were prepared by oxidative homodimerization reactions under Glaser-Hay conditions.…
Single-segment collectors, commonly used in electrospinning, distribute nanofibers randomly over their entire length. To improve the orientation of resultant nanofibers, a multi-segmented collector has been developed having alternate conducting and nonconducting segments. The alignment principle is based upon the attr…
This article reports the synthesis of cobalt ferrite (CoFe2O4) nanoparticles by low-cost sol-gel auto combustion method. The synthesized CoFe2O4 nanoparticles were characterized using X-ray Diffraction (XRD), Field Emission Scanning Electron Microscope (FESEM), Energy Dispersive X-ray (EDX), UV-Visible (UV-Vis), Fouri…
The presence of random arrays of elongated nanostructures with dimensional nonuniformity on the cuticular surfaces of insects endows them with antiwetting characteristics, as exemplified by nanopillar arrays on dragonfly wings and nanocone arrays on cicada wings. But the roles of the nanostructure shape and dimensiona…
The objective of the study is to determine the patterns of regulation of single-walled carbon nanotube accumulation, distribution, and agglomeration in glioma cells exposed to an external electric field. C6 glioma cells were treated with 5 μg/ml DNA wrapped single-walled carbon nanotubes and exposed to bi-phasic elect…
Liquid-like materials have attracted increasing attention, owing to their phonon–liquid electron–crystal feature. As a typical representative, the superionic conductor AgCrSe 2 is regarded as a promising thermoelectric for its intrinsic ultralow lattice thermal conductivity. The primary challenge for achieving high th…
Abstract Carbon nano-onions are approximately spherical nanoscale graphitic shells. When filled with ferromagnetic Fe3C/α-Fe nanocrystals, these structures have several important applications, such as point electron-sources, magnetic data recording, energy storage, and others, that exploit the interaction of either or…
