Influence of Applied Voltages on Mechanical Properties and In-Vitro Performances of Electroplated Hydroxyapatite Coatings on Pure Titanium
Titanium and its alloys have been extensively used in biomaterials due to their bone-compatible modulus, superior bio-compatibility and enhanced corrosion resistance. But the metal implants that contact the body will release ions and scraps. In this study, Hydroxyapatite (HA, Ca 10 (PO 4 ) 6 (OH) 2 ) was coated on a p…
Experimental characterization of the mechanical properties of railway wheels manufactured using class B material
The railway system has an important role in developed countries, it is possible to see, nowadays, passenger trains crossing the Old Continent and achieving impressive speeds in the East; at the same time, cargo wagons are hitting load-by-axle records in North America. Railway wheels are a critical component to this sy…
Structural diversity of alkylzinc complexes with pyrrole-based N,O-ligands: from molecular complexes to coordination polymers
The equimolar reaction of R2Zn (where R = Et or (t)Bu) with pyrrole-based N,O-proligands afforded a series of alkylzinc compounds with a variety of intriguing structures including a hexanuclear macrocyclic complex and 1D coordination polymers with versatile intramolecular or intermolecular bonding modes.
Highly planar thieno[3,2-b]thiophene-diketopyrrolopyrrole-containing polymers for organic field-effect transistors
Two novel thieno[3,2- b ]thiophene-flanked diketopyrrolopyrrole-based copolymers (PTTDPPTVT and PTTDPPSVS) with high planarity were synthesized and studied as semiconductors in OFETs.
Enhancement of encaged electron concentration by Sr 2+ doping and improvement of Gd 3+ emission through controlling encaged anions in conductive C12A7 phosphors
Conductive C12A7:0.1%Gd(3+),y%Sr(2+) powders with different Sr(2+) doping concentrations have been prepared in a H2 atmosphere by a solid state method in combination with subsequent UV-irradiation. The encaged electron concentration could be modulated through tuning Sr(2+) doping and its maximum value reaches 2.3 × 10…
Maltitol-based biodegradable polyesters with tailored degradation and controlled release for bone regeneration
Polyesters based on maltitol and different dicarboxylic acids promoted mineral deposition and directed cells towards osteogenic lineage.
Effects of 2CaO∙SiO2 and 2CaO∙Al2O3∙SiO2 on Primary Slag Melting of Sinters in the Cohesive Zone of a Blast Furnace
To investigate the relation between Al2O3 and the gas permeability resistance in a blast furnace, the effect of Al2O3 on the increment in the slag melt volume and the decrement in the temperature of the slag melt formation has been elucidated by comparing the reactions between liquid olivine and solid 2CaO∙SiO2 and be…
Vibronic Thulium Laser at 2131 nm Q-switched by Single-Walled Carbon Nanotubes
A vibronic Tm:KLu(WO4)2 laser Q-switched with SWCNTs as saturable absorber generated a maximum average output power of 705 mW at ~2131 nm. The shortest pulse duration was 25 ns at 0.62 MHz pulse repetition frequency.
Ultrafast spectroscopy, superluminescence and theoretical modeling of a two-photon absorbing fluorene derivative
A comprehensive study of photophysical and photochemical properties of an unsymmetrical fluorene derivative is presented, including linear absorption, fluorescence excitation anisotropy, photochemical stability, steady-state fluorescence, and fluorescence lifetimes in organic solvents of different polarities. Nonlinea…
Influence of additives on microstructure, mechanical and tribological properties of nanocrystalline Zn–Ni coatings in a novel alkaline bath
Nanocrystalline Zn–Ni coatings with excellent wear resistance can be obtained from a novel alkaline bath. Meanwhile, the effects of additives and Ni content in deposits on wear behaviors and the wear mechanism of Zn–Ni coatings are investigated.
Synthesis, characterization and evaluation of diglycidyl-1,2-cyclohexanedicarboxylate crosslinked polyethylenimine nanoparticles as efficient carriers of DNA
Crosslinked PEI nanoparticles were synthesized, which efficiently transported DNA inside the cells with minimal cytotoxicity.

This work first reported the conversion of CP to PCMs. The ultrahigh adsorption amount, fast kinetics and great regeneration made the PCMs-850-4 as promising adsorbents for the low-cost, highly efficient and fast removal of organic pollutants.
Low temperature high density plasma nitriding of stainless steel molds for stamping of oxide glasses
Various kinds of stainless steels have been widely utilized as a die for mold- and direct-stamping processes of optical oxide glasses. Since they suffered from high temperature transients and thermal cycles in practice, they must be surface-treated by dry and wet coatings, or, by plasma nitriding. Martensitic stainles…
Structural diversification and single-crystal-to-single-crystal transformation of alkaline earth metal-based MOFs regulated by solvent effect
Two pairs of alkaline earth metal-based MOFs have been synthesized by spontaneous self-assembly reactions of Mg(II) or Ca(II) and two tricarboxylate ligands, H3BTTB and H3TCM (H3BTTB = 4,4′,4′′-[benzene-1,3,5-triyl-tris(oxy)]tribenzoic acid; H3TCM = 4,4′,4′′-{[(2,4,6-trimethylbenzene-1,3,5-triyl)tris(methylene)]tris(o…
Following the nanostructural molecular orientation guidelines for sulfur versus thiophene units in small molecule photovoltaic cells
In bulk heterojunction (BHJ) organic photovoltaics, particularly those using small molecules, electron donor and/or electron acceptor materials form a distributed network in the photoactive layer where critical photo-physical processes occur.
