Metalated and free-base A(3)B-type asymmetric phthalocyanines (Pcs) bearing, in the asymmetric quadrant, a flexible alkyl linker of varying chain lengths terminating in a phosphonic acid (PA) group have been synthesized. Two parallel series of asymmetric Pc derivatives bearing aryloxy and arylthio substituents are rep…
Hydroxyls are present as surface terminations of transition metal oxides under ambient conditions and may modify the properties of supported catalysts. We perform first-principles density functional theory calculations to investigate the role of hydroxyls on the catalytic activity of supported gold clusters on TiO 2 (…
The dynamic response of VO2-coated silicon microcantilevers thermally driven over the film’s insulator-to-metal transition was studied using laser light pulses directly incident on the cantilevers. The measured photothermal response revealed very high curvature changes of approximately 2500 m−1 up to pulse frequencies…
Heterogeneous acetylation to a low extent of bleached and unbleached commercial kraft pulps was performed with acetic anhydride without solvents and in the presence of sulfuric acid catalyst. The process was conducted in an effort to change the polarity of studied kraft pulps and to improve their compatibility with sy…
Over 50 years of nuclear fuels and materials irradiation testing has led to many countries developing significant improvements in instrumentation to monitor physical parameters and to control the test conditions in material test reactors (MTRs). Recently, there is increased interest to irradiate new materials and reac…
Equations resembling the Rayleigh-Plesset and Keller-Miksis equations are frequently used to model bubble dynamics in confined spaces, using the standard inertial term RR+3R([middle dot]) (2)/2, where R is the bubble radius. This practice has been widely assumed to be defensible if the bubble is much smaller than the…
The corrosion inhibition properties of ceftadizime (CZD) for mild steel corrosion .in H2SO4 solution were analysed by electrochemical impedance spectroscopy (EIS), potentiodynamic polarization and gravimetric methods. Mixed mode of adsorption (Physisorption and chemisorption) is proposed for the inhibition and the pro…
Although the viscosity of molten metal is very important, the measurement is considerably difficult for high temperature melts. The author's group has developed an oscillating viscometer for high temperature metal. The prediction of the viscosity behavior of the alloys is most useful task because the experimental data…
The Soret maxima of a number of metallotriarylcorroles shift sensitively in response to varying substituents on the meso-aryl groups. The effect is most pronounced for copper corroles but is not seen for silver and gold corroles. In the copper case, the effect has been attributed to a small HOMO–LUMO gap. Chromium-oxo…
Amine-terminated generation 5 poly(amidoamine) dendrimers were utilized as a platform to conjugate fluorescein isothiocyanate and lactobionic acid. The conjugated lactobionic acid moieties enabled effective targeting to human liver cancer cells (HepG2) in vitro, which was demonstrated by both flow cytometry and confoc…
BACKGROUND: The purpose of this study was to develop intraperitoneal hyperthermic therapy based on magnetic fluid hyperthermia, nanoparticle-wrapped cisplatin chemotherapy, and magnetic particles of albumin. In addition, to combine the multiple-killing effects of hyperthermal targeting therapy, chemotherapy, and radio…
The objective of this study was to investigate the inhibitive action of eggplant peel extract toward the corrosion of mild steel in 2M HCl solution by employing weight loss measurements and electrochemical techniques. The results of both methods showed that the corrosion rate is decreasing and inhibition efficiency is…

Abstract Nanoporous metallic glass palladium (PdNPore), which was fabricated by de‐alloying of a glassy metallic alloy Pd 30 Ni 50 P 20 , exhibited a remarkable catalytic activity for the Heck reaction of versatile aryl iodides and aryl bromides. Moreover, the PdNPore can be reused several times without a significant…
Boundary conditions for the equations of the theory of elasticity modified by the presence of the flexoelectric effect have been obtained. It has been shown that these conditions do not generally coincide with the boundary conditions of the standard theory of elasticity. In particular, stresses that are proportional t…
Reliable thermophysical property values of thin films are important to develop advanced industrial technologies such as highly integrated electronic devices, phase-change memories, magneto-optical disks, light-emitting diodes (LEDs), organic light-emitting diodes (OLEDs), semiconductor lasers (LDs), flat-panel display…
In this work, the electronic, structural, elastic, and thermodynamic properties of Ti2AX MAX phases (A = Al or Ga, X = C or N) were investigated using density functional theory (DFT). It is shown that the calculations of the electronic, structural, and elastic properties of these structures, using local density approx…
The structure and magnetic properties of Co 1− X Cu X Fe 2 O 4 were investigated. Cobalt copper ferrites have been synthesized by the double sintering ceramic technique. X-ray diffraction analysis and transmission electron microscopy (TEM) confirmed the formation of single-phase cobalt ferrite nanoparticles. The parti…
Leather processing involves conversion of putrescible hide/skin into nonputrescible leather. This results in generation of both solid and liquid wastes. Solid waste disposal is increasingly becoming a huge challenge to tanners due to paucity of landfill sites and strict environmental legislations worldwide. Hence, fin…
Bark, as a residue from trees, is mostly used for thermal energy production, but a better utilization of this resource was considered as an alternative raw material for wood-plastic composites (WPCs). The influence of bark, wood, and blending of bark and wood flour content of the poplar tree on the mechanical characte…
