We prepared robust cross-linked (x-linked) multilayer films under visible light irradiation with the catalysis of a Ru(ii) complex. The x-linking is achieved by the coupling reaction between phenol group and primary amine group within the self-assembled multilayer films that were prepared beforehand. Three kinds of po…
This study examined the effect of the cross-linking with riboflavin-ultraviolet A (UVA) irradiation on the chemical bonds and ultrastructural changes of human sclera tissues using Raman spectroscopy and atomic force microscopy (AFM). Raman spectroscopy of the normal and cross-linked human sclera tissue revealed differ…
We perform Monte Carlo simulations to analyze the equilibrium dynamics and the long-time structural relaxation decay of columnar liquid crystals of disk-like colloidal particles. In the wake of recent studies on the columnar mesophase of hard calamitic (rod-like) colloids, we now focus on the diffusion of their discot…
It has been reported that tablets of clarithromycin (CAM), a 14-membered macrolide antibiotic, are especially stable under low pH conditions such as in gastric fluid, and showed excellent antibacterial efficiency even though CAM molecules themselves are rapidly decomposed. Therefore, we aimed to clarify the stabilizat…
Novel phosphors of BaLa 2–x Bi x ZnO 5 exhibiting an emission in the blue region have been synthesized using a vibrating milled solid state reaction with metal oxides. The x-ray diffraction pattern indicates that all of the peaks can be attributed to the single phase. A double exponential decay behavior was observed i…
Low-temperature scanning tunneling microscopy and spectroscopy have been employed to analyze the local electronic structure of the (111) surface of a ceria thin film grown on Ru(0001). On pristine, defect-free oxide terraces, the empty 4f states of Ce(4+) ions appear as the only spectral feature inside the 6 eV oxide…
Recent developments indicate that Pluronic block copolymers can implement more than only inert carrier functions by being biological response modifiers Pluronics cause drastic sensitization of MDR tumors to various anticancer agents, enhance drug transport across the blood brain and intestinal barriers, and causes tra…
Inorganic/organic (hybrid) complementary electrochromic devices (ECDs) of the type [transparent conducting oxide (TCO)//inorganic counter electrode/hydrophobic electrolytic membrane/polymeric working electrode//TCO] were assembled. The working electrodes consisted of spin-coated polymer films prepared by moderator-con…
Complex experimental investigations of the structural, optical, and magneto-optical properties (magnetotransmission, magnetoreflection, and transversal Kerr effect, as well as the magnetoresistance, of La 0.7 Ca 0.3 MnO 3 epitaxial films indicate that magnetoreflection and magnetotransmission in manganite films can re…
The context of the this research is the development of nanoparticulate systems exhibiting long circulation times in the blood pool, loaded with X-ray contrasting compounds, to be used as blood pool contrast agents in computed tomography. This study presents an original, new and simple formulation of radiopaque nano-em…
A facile strategy has been successfully developed to fabricate hollow crosslinked polyphosphazene submicrospheres. The mean diameter of interior cavities can be well adjusted (typically in a range from 100 to 300 nm). Interestingly, there are plenty of uniform mesopores distributing in the organic-inorganic hybrid she…
The reversible hydrogen storage/release phenomena on a lithium–fullerene composite of lithium fulleride (LinC60) were reported. NMR analyses revealed that LiH and C60Hn were formed after hydrogen storage. Molecular hydrogen was stored as a proton (H+) incorporated with C60 and a hydride (H−) incorporated with a Li ion.
A mechanistic study regarding the synthesis of aromatic polyimides (PIs) under hydrothermal conditions is presented. We demonstrate evidence that the first step of the reaction is the formation of a nylon type salt, which can be isolated. Upon heating the salt in the presence of water at 180 °C, polyimides are formed…
Liposomes have been widely used as promising drug delivery systems. The stabilization of liposomes however remains challenging, especially when surface binding properties are involved. In this work, we reported carboxymethyl dextran-coated liposomes (CMD-LIPs), in an attempt to improve their stability, surface binding…
1,3-Alternate calix[4]arene with para-phenylene spacers connecting nitroxide monoradicals and high-spin (S = 1) diradicals provides tetraradical and octaradical scaffolds that possess conformations with slow electron spin relaxation rates (1/T(1)). Such scaffolds may facilitate tuning of relaxation rates that are more…
Abstract The article presents numerical investigations of high-contrast grating mirrors. First, it shows the basis of a new numerical method for computing the parameters of the grating and next it describes the results of the analysis of the manufacturing imperfections impact on the reflection coefficient. Finally, it…
We present the preparation of millimetre-sized liquid marbles with strong mechanical strength and good deformability using self-assembled fluoroalkylsilane functionalized titanate nanobelt powder. The strength and deformability of the marbles are adjustable by changing the intrinsic wetting state of the titanate nanop…
The three dimensional microstructure and fluid conductivity of hydrogels are major determinants of their physical and mechanical properties. Under free fluid flow conditions, highly hydrated fibrillar collagen gels expel fluid and undergo a gravity driven consolidation process (self-compression). Within minutes of the…
The results of studies of the hydrophobicity of composite coatings on titanium formed using the method of plasma electrolytic oxidation (PEO) with further treatment by superdispersed polytetrafluoroethylene and its low-molecular fractions are presented. The chosen regimes of application of fluoropolymer materials of d…
Serial sectioning by FIB/SEM and 3D reconstruction was used to study the microstructure-performance correlations for (LSM) and 8 mol% yttria-stabilized (YSZ) solid oxide fuel cell (SOFC) composite cathodes. In this study, the starting LSM and YSZ particle sizes were varied, keeping overall weight fractions of each sol…
