Nowadays, SiC is one of the refractory materials which is used widespread because of its unique properties like structural stability in high temperatures. SiC nano whiskers are important in reinforcement of different kinds of composites like ceramic base materials, thanks to their outstanding mechanical, thermal, and chemical properties like low expansion coefficient, high thermal resistant, hi...

Extremely high capacity hard carbon for Na-ion battery, delivering 478 mAh g−1, is successfully synthesized by heating a freeze-dried mixture of magnesium gluconate and glucose MgO-template technique. Influences synthetic conditions nano-structures on electrochemical Na storage properties in the are systematically studied to maximize reversible capacity. Nano-sized MgO particles formed matrix p...

In order to explore the modification effect of carbonization time on nano-MgO-modified cement soil, unconfined compressive strength tests soil with times 0 h, 6 1 d, 2 d and 4 were carried out. A method for normalizing stress–strain curve was proposed, influence nano-MgO content investigated from three aspects strength, peak strain energy dissipation. The test results show following: (1) modifi...

Silica exists in Rice husk, an agriculture waste, as a naturally occurring phase. In first step, acidic pre-treatment and calcination of the rice husk were performed to obtain nano-silica, in which various sizes of the nano-silica, totally with sizes under 80 nm, were achieved. Second, to reduce nano-silica to elemental Si and subsequently formation of the composite, Mg used as the reducing age...

The basic building blocks of nano-structured hierarchical cellular materials are nano-sized wires or plates. Due to the effects of surface elasticity and the initial stress/strain, their bending, torsion, stretching and transverse shear rigidities are not only size-dependent, but also tunable and controllable over a large range. Based on the closed form results of the bending, torsion, stretchi...

Regeneration of complex orthopedic tissues (such as ligament, bone, and the tendon-to-bone insertion site) is problematic due to a lack of suitable biomaterials with the appropriate chemical and mechanical properties to elicit the formation of tissues with similar structure, organization, and functionality to natural tissues. Additionally, a non-trivial fraction of implanted biomaterials acquir...

Extensive use of nanoparticles (NPs) in consumer and industrial products has led to concerns about their potential environmental impacts; however, the influences of different NPs (e.g., nZVI (nano zero-valent iron), Ag NPs, Fe2O3 NPs and MgO NPs) on the anaerobic digestion of sludge have not yet been studied in depth. Additionally, a new guideline or the use of different NPs in the anaerobic di...

Magnesium oxide (MgO) thin films were deposited on silicon and glass substrates by the radio frequency (RF) sputtering method. The MgO annealed at 400 ⁰C for 4h. effect of working pressure structure optical properties was investigated. Structural characterization determined using X-ray diffraction (XRD) XRD results showed presence dominant peaks corresponding to (200) (220) lattice planes MgO. ...

We report the results of spatial resolution and conversion efficiency measurements on new fluorochlorozirconate and lithium-borate glass-ceramics that are being researched for x-ray and thermal neutron imaging applications. The sensitivity of the fluorochlorozirconate glass-ceramics containing BaCl2:Eu nano-crystallites is up to 80 % of that found in BaFBr(1000ppm Eu), which is the material use...

Highly localized and very fast electron amplification of microchannel plates (MCP) enables a large number of high resolution and high sensitivity detection technologies, which provide spatial and/or temporal information for each detected photon/electron/ion/neutron. Although there has been significant progress in photocathode and readout technologies the MCPs themselves have not evolved much fr...
