After tooth extractions the alveolar bone reabsorbs due to the lack of mechanical loading of the mastication. Such reabsorption hinders the rehabilitation of edentulous patients due to possible non-adaptation of the prosthesis and lack of height for implants, causing various health damages. To minimize reabsorption gr…
Abstract Since their discovery by Iijima in 1991 [1], carbon nanotubes have sparked unwavering interest among researchers all over the world. This is due to the unique properties of carbon nanotubes (CNTs). Carbon nanotubes have excellent mechanical and electrical properties with high chemical and thermal stability. I…

In the framework of the Advanced Demonstration and Test Reactor Options (ADTRO) study commissioned by the U.S. Congress and executed by the Department of Energy through prominent U.S. National Laboratories, Westinghouse Electric Company proposed a pre-conceptual design of a Demonstration Lead Fast Reactor (DLFR) inten…
a (*),Omid Forough(**), Cristina Gabriela Onate Salazar(*) (*) Politecnico di Torino (Italy), colorado school of mines (USA) A. B. Unknown Affiliation, City, Country. In the recent years, Earth Pressure Balance (EPB) shields have been successfully used in many tunnels in urban areas. One of the critical issues for suc…
For the rapid hardening of concrete, various types of calcium aluminate composite have been used for special purpose as shotcrete or rapid repairing in construction field. However, high cost of calcium aluminates is demerit in the point of expanding usage. In recent years, a new binder for rapid hardening has been int…
Accompanying the improvement of vehicle interior quietness in recent years, there has been a need to manufacture low-noise transmission gears at low cost. In response to this need, we adopted a gear honing process as the finishing method following heat treatment in order to reduce the source of gear noise. Previously,…
Caltrin (calcium transport inhibitor) is a family of small and basic proteins of the mammalian seminal plasma which bind to sperm cells during ejaculation and inhibit the extracellular Ca2+uptake, preventing the premature acrosomal exocytosis and hyperactivation when sperm cells ascend through the female reproductive…
In the present work the liquid morphology, under partially saturated conditions inside two carbon aerogel and xerogel samples, was investigated using the low-field nuclear magnetic resonance (NMR) relaxometry. Information about the tortuosity of the two samples was also extracted using pulse field gradient NMR diffuso…
Interstitial phenomena functioning as surface roughness, voids and irregularities in nano scale influence the heat transfer and these effects become very significant with the reduction of material size. Non-equilibrium Molecular Dynamics (NEMD) simulation was employed in this study to understand the effects of interfa…
We demonstrate a vertical-cavity surface-emitting laser, with an integrated all-dielectric metasurface, generating vortex-like coherent state in the Laguerre-Gauss basis. This coherent photonic device was theoretically calculated and experimentally characterized to achieve both high transmission efficiency and high OA…
Dimensional stability of knitted fabric is a key factor for garments manufacturing. To make the fabric dimensionally stable fabric width, shrinkage, spirality and areal density should be under tolerance limit. Knitted fabric structure plays an important role on dimensional properties. This paper focuses on the fabric…
This work is aimed to study the plasticizing effectiveness of different cardanol derivatives, characterized by different yields of epoxidation, for the production of soft PVC. The properties of the cardanol derived plasticizers were compared to the properties of commercial plasticizers, both phthalates and natural der…

The present study on the microstructure evolution of hot form-quench (HFQ) AZ31 twin roll cast magnesium alloy attempt to provide an understanding on the grain structure and heterogeneous intermetallic phase formation in the alloy and texture development following the HFQ process. Grain recrystallization and partial d…
Electrochemical noise (EN) was used to study the corrosivity of haze under Tianjin’s urban atmosphere by using two electrochemical corrosion probes made by T91 and Q235B steels. Experimental results indicate that temperature, relative humidity and concentrations of pollutants (PM10, PM2.5, SO2, NO2 and O3) can affect…
Foam injection molding uses physical blowing agents under high pressure and temperature to produce structural foams having a cellular core and a compact solid skin. This technology is particularly interesting for biodegradable polymers, which often present a very narrow processing window, with the suitable processing…
Hydrogen is considered to be a clean, economical and safe renewable energy source that would be ideal to replace fossil fuels, because it is light, highly abundant and its oxidation product (water) is environmentally benign. However, hydrogen is easy to burn (the chemical energy per mass of hydrogen is at least three…
With the increasing of the traditional energy, the utilization of traditional energy and new energy researching is an important direction for the development of the new era. Phase change material, is a new era for the sustainable development of new energy research. The phase change material wrapped into microcapsules…
We report the synthesis of a photocatalytic composite of spherical porous hydroxyapatite (sHAp) and TiO2. sHAp was prepared by a wet method using simulated body fluid as a slurry and was then mixed with a TiO2 sol to obtain the sHAp + TiO2 composite. The TiO2 content of sHAp + TiO2 was ~7.8 wt. %. sHAp+TiO2 showed pho…
