BACKGROUND AND OBJECTIVES: AD-MSCs (adipose-derived mesenchymal stem cells), as an easy obtainable population of multipotent cells, have been successfully applied in many diseases in animals. Having very similar properties and morphology to these collected from bone marrow, are very attractive object for regenerative…
Using the mixed ligands bis(3-pyridylformyl)piperazine (3-bpfp) and 5-nitroisophthalic acid (H2NIPH) or 3-nitrophthalic acid (H2NPH), four two dimensional (2D) copper or cadmium coordination polymers with different structural features formulated as [Cu(3-bpfp)(NIPH)(H2O)] (1), [Cu(3-bpfp)0.5(NPH)(H2O)2] (2), [Cd(3-bpf…
Orthorhombic Cu3SnS4 nano-cuboids and nanosheets were synthesized by using monoclinic Cu31S16 nanocrystals as seeds. Transmission electron microscopy and powder X-ray diffractometry were adopted to investigate the resultant nanocrystals and the structural transformation of monoclinic Cu31S16 to orthorhombic Cu3SnS4.
We investigated the effect and feasibility of hyperthermia treatment on subcutaneous pancreatic cancer in female Kunming mice, using a murine pancreatic cancer cell line (MPC-83) established by us and found in this study to originate from epithelial pancreatic acinus. Magnetic fluid (MF) with ferromagnetic particles o…
Current lithium-ion battery (LIB) technologies are all based on inorganic electrode materials, though organic materials have been used as electrodes for years. Disadvantages such as limited thermal stability and low specific capacity hinder their applications. On the other hand, the transition metal oxides that provid…
This paper reports the optical effects of a two-dimensional (2D) SiNx photonic crystal layer (PCL) on Y3Al5O12:Ce3+ (YAG:Ce) yellow ceramic plate phosphor (CPP) in order to enhance the forward emission of YAG:Ce CPP-capped high-power white light-emitting diodes (LEDs). By adding the 2D SiNx PCL with a 580 nm lattice c…

HiRadMat (High Irradiation to Materials) is a new facility under construction at CERN designed to provide high intensity pulsed beams to an irradiation area where material samples as well as accelerator component assemblies can be tested. The facility uses a 440 GeV proton beam extracted from the CERN SPS with a pulse…
This work presents a scanning electrochemical microscopy (SECM)-based in situ corrosion probing methodology that is capable of monitoring the release of zinc species in corrosion processes. It is based on the use of Hg-coated Pt microelectrodes as SECM tips, which offer a wider negative potential range than bare plati…
A comprehensive understanding of chemical interactions between water and actinide dioxide surfaces is critical for safe operation and storage of nuclear fuels. Despite substantial previous research, understanding the nature of these interactions remains incomplete. In this work, we combine accurate calorimetric measur…
The Li–Co–O and Li–Ni–O systems, used as cathodes in lithium ion batteries, have been investigated by means of ab initio calculations and empirical methods. An approach based on ab initio calculations to obtain accurate enthalpies of formation for transition metal oxides is proposed. With the obtained enthalpies of fo…
A new dinuclear copper salicylaldehyde-glycine Schiff-base complex [Cu(2)(Sal-Gly)(2)(H(2)O)(2)] was synthesized and structurally characterized. [Cu(2)(Sal-Gly)(2)(H(2)O)(2)] crystallized in the monoclinic system in the P2(1)/c space group. The molecule is a dinuclear complex, formed by two [Cu(Sal-Gly)(H(2)O)] units.…
New parameters for the electronegativity equalization model (EEM) and the split-charge equilibration (SQE) model are calibrated for silicate materials, based on an extensive training set of representative isolated systems. In total, four calibrations are carried out, two for each model, either using iterative Hirshfel…
To increase the biochemical efficiency of biosynthetic systems, metabolic engineers have explored different approaches for organizing enzymes, including the generation of unnatural fusion proteins. Previous work aimed at improving the biosynthesis of resveratrol, a stilbene associated a range of health-promoting activ…
The drying of sawdust was studied in a conical spouted bed pilot plant in order to adapt this feed for the pyrolysis process. Air at different temperatures was used and the effect of sawdust particle size and operating gas velocity was studied. Batch operation was performed with no internal device and with nonporous a…
Three dimensionally ordered macroporous (3DOM) silicon films have been made via ordered polystyrene (PS) templates by electrodeposition from an ionic liquid (IL). For this purpose, the ionic liquid 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)amide ([Py(1,4)]Tf(2)N) with SiCl(4) dissolved in it was used a…
The mechanical properties of monolithic metallic glasses depend on the structures at atomic or subnanometer scales, while a clear correlation between mechanical behavior and structures has not been well established in such amorphous materials. In this work, we find a clear correlation of (27)Al NMR isotropic shifts wi…
In the last decade, research concerning nanoporous siliceous materials has been focused on mesoporous materials with intrinsic zeolitic features. These materials are thought to be superior, because they are able to combine (i) the enhanced diffusion and accessibility for larger molecules and viscous fluids typical of…
Synthesis of the [Ru(dcbpy)(2)(OQN)](+) complex is reported in which dcbpy and OQN(-) are the bidentate 4,4'-dicarboxy-2,2'-bipyridyl and 8-oxyquinolate ligands, respectively. Spectroscopic, electrochemical, and theoretical analyses are indicative of extensive Ru(OQN) molecular orbital overlap due to degenerate Ru d(π…
The MoS2 nanocrystals coupled with anatase nanoparticles were prepared by the solvothermal method at relatively low temperatures. It was determined that the materials consisted of 15–20 nm diameter anatase nanoparticles with highly dispersed MoS2 nanocrystals of approximately 3–7 nm in size. Visible light absorption i…
