A series of composite materials containing polyhedral oligomeric silsesquioxanes (POSS) and hydrogenated butadiene-acrylonitrile rubber (HNBR) were prepared. The goal of the work was to evaluate the effect of the type and reactivity of functional groups in the POSS cage on properties of the resulting elastomeric nanoc…
We theoretically study chemical spin doping into single porphyrins connected to nanoelectrodes via benzenethiols, ethynyl-benzenethiols, and vinyl-benzenethiols using the adsorption of a nitric oxide (NO) molecule. For all three anchoring groups, the adsorption of a NO molecule injects one spin into single-molecule ju…
Mechanical and thermal properties significantly affect many aspects of machining, such as chip formation, cutting forces, cutting temperatures, and surface integrity of machined products. One of the most important mechanical properties is the material flow stress, which is governed by the field variables including the…
The synthesis of polymer brushes containing poly (methyl methacrylate) (PMMA) chains grafted from hydroxyapatite (HAP) particles was disscussed. Surface of commercially available hydroxyapatite was first modified with atom transfer radical polymerization (ATRP) initiator and hydrophobized with isobutyric acid, and the…
The optimal conditions of prepared magnesium hydroxide using dolomite as raw material were systematically explored by carbonization. The influence between the factors of reactions and the extraction rate of magnesium hydroxide was studied. The structure and composition of product were analyzed by Fourier transform inf…
Highly concentrated aqueous solutions of lithium salts (LiCl, LiNO3, and LiClO4) and a nonionic surfactant (10-lauryl ether) form lyotropic liquid crystalline mesophases. The new mesophases display high ionic conductivities (10−2–10−4 S cm−1) over a broad temperature range (−10 to 80oC) and exhibit excellent behavior…
Shape memory alloy (SMA) wires are capable of providing contractile strain mimicking the functionality of muscle fibers. They are promising for the development of biomimetic robots due to their high power density and desired form factor. However, they suffer from significantly high power consumption. The focus of this…
It is shown analytically that plasmon-mediated magnetic response can be realized at optical frequencies in nanostructured magnetized metallic ferromagnetics under certain restrictions on their electronic subsystem. According to the results of our calculations, the occurrence of magnetic resonance in the visible spectr…
ABSTRACT In this paper, we demonstrate single‐sided screen‐printed emitters in thin monocrystalline Czochralski silicon (Cz‐Si) wafers with an improved gettering of iron compared with conventional double‐sided POCl3 emitters. The phosphorus dopant pastes used have to be chosen carefully to provide a sufficiently low e…
Time‐of‐flight SIMS was used to study monolayers of the siloxane terminated porphyrin Zn‐TESP (C 67 H 75 N 5 O 5 SiZn) attached to magnesium oxide (MgO) substrates in a silanisation reaction. Time‐of‐flight SIMS spectra show dependence of the coverage on the preparation temperature. The fragmentation pattern of the po…

The role of laparoscopic HIPEC has been reported by several centers around the world as a promising and appealing therapeutical alternative in the management of patients suffering of advanced intra-abdominal malignancies and peritoneal carcinomatosis. Laparoscopic HIPEC is implemented as a neoadjuvant and adjuvant the…
The oxidation of noradrenaline (NA) using copper phthalocyanine (CuPc) as catalyst was investigated by UV-Vis spectroscopic analysis. The influence factors of catalytic efficiency, such as catalytic time and temperature, the pH value of solution and the amount of CuPc, have been investigated. The results indicated tha…
A plasma electrolytic oxidation (PEO) ceramic coating process was used to form ceramic MoS2/oxide coatings on aluminum. The tribological properties of the PEO-MoS2 coatings were evaluated by sliding wear tests under the dry and lubricate conditions at the room temperature. The test results showed that the solid lubric…
The present studies are to investigate the microstructure features and macroscopical hardness during transformation from austenite to pearlite without and with 12T magnetic field on Fe-1.1%C alloy. It is found that 12T magnetic field can increase the area fraction of abnormal microstructure and the average width of se…
PEG/ ammonium sulfate aqueous two-phase systems were supplied to separate GMP. It was found that PEG molecular weight, PEG concentration and ammonium sulfate concentration could influence the partitioning of GMP. The data of experiment showed that 18% (w/w) PEG6000 and 15% (w/w) ammonium sulfate were the optimum syste…
The effects of Zr addition on the as cast microstructure, tensile and creep properties of Mg–3·8Zn–2·2Ca (wt-%) magnesium alloy were investigated. The results indicate that adding 0·19–0·81 wt-%Zr to the Mg–3·8Zn–2·2Ca does not cause the formation of any new phases but causes the morphology of the Ca2Mg6Zn3 phase to c…
The aim of this work was to obtain elastomer composite filled with carbon fillers with different structure. Three types of carbon black were used as reinforcing fillers: FEF N550, Colour Black FW200, Printex XE2B. In order to improve dispersion of fillers, different dispersing agents were used: anionic, cationic, noni…
We investigated the preparation of porous film of cellulose-based graft copolymer by breath figure method. The effects of substrate, solvent, graft density and graft length on the formation of porous film were elucidated. The results showed that ordered porous films could be facilely formed on the glass and mica subst…
