We report the regiospecific synthesis of the first chloro-substituted porphycenes as two positional isomers of β-tetrachlorotetramethoxyporphycene. The positional effect of the substituents on these isomers could be clearly distinguished in their structure and photophysical properties.
Triiodothyronine incorporated nanofibers and its impact on wound healing.
It has been reported that Pd-Au bimetallic catalysts display improved catalytic performance after adequate calcination. In this study, a model catalyst study was conducted to investigate the effects of annealing in oxygen on the surface structures of Pd-Au alloys by comparing the physicochemical properties of Pd/Au(11…
We have studied the interaction of a polymeric water soluble anthracenyl derivative () with salmon testes DNA. The results from UV-Vis, fluorescence, Fourier transform infrared (FT-IR) and circular dichroism spectroscopies indicate that the groove binding process regulates the interaction between and DNA. The binding…
Herein, we report the preparation of crystalline mesoporous iron phosphate (FePO4, hereafter abbreviated as FeP) materials with 2D-plates and 1D-rods in the presence of an amphiphilic block copolymer (F127), iron nitrate, and phosphoric acid. The dimensionality of mesoporous FeP can be switched by changing the polarit…
In this study, structural, electronic, and magnetic properties of monolayer MoS2 on decorated AlN nanosheets have been systematically investigated using density functional theory with van der Waals corrections. The results indicate that the surface microstructure of the AlN substrate and stacking patterns significantl…
Dissolution of metal-based nanomaterials (MNMs) leads to the release of metal ion species; this phenomenon is a major concern affecting the widespread application of MNMs because it can affect their subsequent biodistribution patterns and toxic responses toward living biological systems.
The catalytic and photo-catalytic activity of well-defined anatase TiO2 nanocrystals for the partial oxidation of methanol was investigated using temperature-programmed desorption (TPD) in ultra-high vacuum in order to determine how crystallite size and shape affect reactivity. The TiO2 films used in this study were p…
Four tetranuclear lanthanide compounds with formulas [Ln4(HL)2(H3L)2(H2L′)2(PhCOO)2]·6CH3OH (Ln = Nd (1), Sm (2) and Gd (3)) and [Dy4(DFMP)2(H2L)2(HL)2]·6CH3OH·2H2O (4) (H4L = 3-((1,3-dihydroxy-2-(hydroxymethyl)propan-2-ylimino)methyl)-2-hydroxy-5-methylbenzaldehyde and H3L′ = 3-(4,4-bis(hydroxymethyl)oxazolidin-2-yl)…
The deep red phosphor Sr <sub>4</sub> (PO <sub>4</sub> ) <sub>2</sub> O:Eu <sup>2+</sup> , which has an excitation peak around 450 nm for blue LED applications, is reported.
Tetraarylpyrazoles are synthesized from commercially available materials in three steps and found to exhibit Aggregation Induced Emission Enhancement (AIEE) characteristics. Removing one aryl unit from tetraarylpyrazole leads to Aggregation Caused Quenching (ACQ), thus the number of aryl groups plays an important role…
Fluorescent dyes have become increasingly important in cell biology since they enable high signal-to-noise and selectivity in visualizing subcellular organelles. Photoactivatable dyes allow for tracking and monitoring of a subset of cells or organelles. Here, we report the synthesis and application of a new class of l…
Polymers typically have intrinsic thermal conductivity much lower than other materials. Enhancement of this property may be obtained by the addition of conductive fillers. In this research, epoxy nanocomposites with exfoliated graphite nanoplatelets are prepared and characterized. The chosen approach requires no surfa…
GY785 is an exopolysaccharide produced by a mesophilic bacterial strain Alteromonas infernus discovered in the deep-sea hydrothermal vents. GY785 highly sulfated derivative (GY785 DRS) was previously demonstrated to be a promising molecule driving the efficient mesenchymal stem cell chondrogenesis for cartilage repair…
We study atomic and electronic structures of hexagonal boron nitride (h-BN) bilayers on the basis of the first-principles density-functional calculations. The interlayer distances between two atomic layers in h-BN bilayer and the band gaps are calculated under biaxial tensile strains. It is found that the interlayer d…
A Ca-based layered double hydroxide (LDH) was synthesized from blast furnace slag (BFS) via a facile and low-cost manufacture process. The synthesis was performed through a two-step method including (i) an acid-dissolution and (ii) an alkali-precipitation process using BFS as a sole metal source. The formation of Ca–A…
The influence of ethylenediaminetetraacetic acid disodium (EDTA) on the corrosion behavior of carbon steel in 0.5M HCl solution has been investigated using open circuit potential (OCP), potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and weight loss measurements. The surface of the carbon st…
The effect of linseed oil (LO) on the corrosion of carbon steel in 1 M HCl solution was investigated using potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) technique and weight loss measurements. The inhibiting action increases with the concentration of the tested inhibitor. The highest effic…

The surface…
With Nb-Ti-stabilized 430 ferritic stainless steel(NTS430FSS) and SUS 430 ferritic stainless steel(SUS430FSS) as experimental materials, the influence of precipitation on intergranular corrosion resistance was investigated. A series of aging treatment were carried out. The free-exposure corrosion test and double loop…
