O reparo é o processo responsável pela substituição dos tecidos lesados por elementos novos, sadios e ocorre através da proliferação de tecido conjuntivo neoformado, vascularizado (cicatrização) ou por tecido igual ao original (regeneração). A regeneração é o processo responsável pela restituição da integridade anatôm…
Heavy metal contamination to Poyang Lake is increasingly severe. Bellamya aeruginosas, the dominant species of bellamya in Poyang Lake, was chosen in this project to carry out a proteomics study, because they obtain nutrients from sediments directly and have a strong heavy metal enrichment capability. To get a better…
Mesoporous titanium dioxide/graphitic carbon microspheres were synthesized by a simple nanocasting route using monodisperse silicon dioxide microspheres as the template. The characterize and the morphology of the titanium dioxide/graphitic carbon microspheres have been analyzed by means of XRD, N2-sorption, SEM, TEM,…
Electrospray deposition (ESD) is a widely used solution process which employs electric force to transform a liquid into a thin film through the formation of fine liquid droplets. In their Letter on pp. 154–157, Liao et al. demonstrate that the high-voltage rectangular pulse driven ESD can provide a way to probe the ef…
The rheological properties of sodium alginate (SA)/agar (AR)/montmorillonite (MMT) solutions were investigated using a rotational viscometer. The dependence of solution apparent viscosity on rotation speed, MMT proportion and solution temperature were researched systematically. Furthermore, the relation of apparent vi…
The paper aims to study the influence of high temperature processing on the substructure of laser shock processed titanium alloy. The titanium alloy specimens were first treated by laser shock processing (LSP), then treated at 700°C for three hours and air cooled to the room temperature to investigate the influence of…
We report a facile and efficient way to fabricate sensitive substrates for surface-enhanced Raman scattering (SERS) via sputtering Au nanoparticles on the surface of porous anodic aluminum oxide (AAO). This substrate could reduce the detection limit of Rhodamine 6G (R6G) to 10-12 M. Moreover, it exhibits excellent rep…
A azamacrocyclic compound with carboxyl branch, 5,5,7,12,12,1-hexamethy-1,4 ,8,11-tetraazacyclo- tetradecane-N/-acetic acid(L), and its neodymium complex ware synthesized and characterized. The mode of combination of the neodymium complex with DNA was investigated by UV-vis absorption spectroscopy methods. The cutting…
BET (Brunauer Emmett and Teller) surface area and pores distribution for the samples DX 09 Carbon were measured for of DX 09 carbon by N2 adsorption (195 °C) with Autosorb-1C (American Quantachrome Company).The adsorption of benzene over DX 09 Carbon was measured in the static vacuum adsorption equipment, which was se…
A thin cylindrical tube model was established. Its energy absorption property was analyzed when crushing through finite element method. Then its validity was verified through the corresponding experiment. On the basis of the above research, two different material tubes were selected which were aluminum alloy 6060 and…
Gamma-valerolactone (GVL) represents a promising future source for both fuel alternatives and renewable materials. It can be formed from the hydrogenation of levulinic acid (LA). However, when lower cost unprocessed biomass is utilized to form levulinic and formic acid, other organic compounds are created, primarily f…
This paper choose three kinds of explosives and two kinds of charge structure, the inner and outer layer, the left and the right structure. It studies the energy coupling between the two parts of explosives and the influence of charging way of energy output structure. Ls-dyna is used to numerically simulate the proces…
Graphite oxide (GO) is an important material of wide applications. Owing to its good mechanical property, the GO sheet is always expected to be stable and remains flat on various substrates. Here we demonstrate for the first time an unexpected behavior of the GO sheet on oxygen deficient ZnO film, namely the spontaneo…
Considerable progress to synthesize magnesium diboride (MgB2) films by electron-beam annealing has been made. A series of MgB2 films with a Tc higher than 35 K had been fabricated. MgB2 film superconductivity is affected by electron-beam accelerating voltage, beam current, annealing duration, beam spot size and Mg/B r…
This issue of the Israel Journal of Chemistry honors Professor Shimon Vega on the occasion of his 70th birthday. Starting with his M.Sc. work on paramagnetic solids and his Ph.D. thesis on pure nuclear quadruple resonance, Shimon proceeded to become one of the leaders of modern nuclear magnetic resonance spectroscopy…
Conversion coatings on cast AZ91D magnesium alloy were prepared in the manganese dihydro phosphate baths. The corrosion behavior of the coated and uncoated alloys has been investigated by polarization curve methods. The morphology and composition of coated surfaces were investigated by scanning electron microscopy (SE…
The Sr based ceramic thin films were deposited on Si substrate by RF magnetron sputtering method. And Sr based thin films were annealed at 500～700℃ using RTA. The surface roughness showed about 2.4 nm in annealed thin film at 600℃. The capacitance density of Sr based thin films were increased with the increase of anne…
Fuel Cell Vehicle (FCV) is the ideal solution for Sustainable Mobility in the future. A new type of hydrogen fuel battery –Lithium-ion battery hybrid power system was introduced; The current hydrogen fuel cell vehicles power system and automotive hydrogen storage system at home and abroad are summarized. Energy effici…
The corrosion behavior of stainless steel and carbon steel in the mortars suffered stress is studied by electrochemical tests. The results show that the corrosion of rebar is accelerated as the magnitude of stress increasing. Under the same stress magnitude, compressive stress more seriously degraded the corrosion res…
The cover picture shows the deposition cycle of a (Ti–O–C6H4–N=)n-type thin film with TiCl4 and 4-aminophenol as precursors. The atomic/molecular layer-by-layer growth process is carried out by employing a combination of the atomic and molecular layer deposition (ALD/MLD) techniques. The combined ALD/MLD technique pro…
