Powder of BaZrO3was firstly synthesized by a solid phase method with BaCO3and ZrO2as starting materials, and then BaZrO3crucible was prepared by a cold isostatic pressing method as well as asolid phase sintering process. The crucible prepared was used for vacuum induction melting experiment of TiNi alloys. The constit…
Experiments on dynamic mechanical performance of granite are carried out under uniaxial cyclic impact loads by using a modified large diameter split Hopkinson pressure bar(SHPB).The dynamic characteristics of the granite specimens and the laws of the energy absorption are analyzed.The cumulative damage of the granite…
Self-healing is a basic and essential property of living organisms and a great challenge for materials sciences. Over the last decade self-repair mechanisms found in plants have proved to be promising role models for the development of bio-inspired self-healing materials. Biological self-repair processes typically can…
The susceptibility to hydrogen embrittlement of two types of high strength austenitic stainless steels containing a small amount nitrogen and niobium were investigated by conducting a series of slow strain rate tests (SSRT) and fatigue crack growth tests in hydrogen gas with a pressure of around 100 MPa. The JIS-SUS30…
The electrochemical property of RuO2 nanosheets in acetic acid-lithium acetate buffered electrolytes was studied in an attempt to understand the charge storage mechanism in neutral solutions and to improve the charge storage capability of aqueous hybrid capacitors. High specific capacitance and good rate capability we…
Dimethyl ether (DME) has been considered a potential and promising energy alternative for petroleum subproducts due to its good burning characteristics, and to its high cetana content which is superior to that of diesel. Furthermore, DME can be considered a cleaner fuel than diesel. DME can be produced by dehydration…
In this investigation two types of heat treatments, solutionizing and ageing were employed to nickelaluminium bronze (NAB alloy) containing 10% Al, 5% Fe and 5% Ni as the alloying elements. Heat treatment was done to access their influence on the microstructural and hardness. Solutionizing temperature carried out at 8…
Poly (lactic acid) (PLA) is an aliphatic polyester and ecofriendly material of a natural origin with biodegradable properties. The monomer for PLA is lactic acid obtained from the fermentation of sugar and vegetables like corn and cassava. This study investigated the effect of heatsetting and wet processes on the tens…
Cell migration plays a crucial role in embryonic development, wound healing, regeneration, inflammation, and immune response, as well as in dissemination of malignant tumors. Vimentin is the marker of migrating cells, but its role in cell migration is still unclear. However, recent studies have revealed novel function…
Encapsulation of therapeutic drugs inside nanoparticles has become the new norm in the field of drug delivery. Nanoparticles increase the therapeutic efficacy of the drugs by providing high loading efficiencies, shielding when in circulation, ability to target tumors, enhanced accumulations, and triggered release insi…
To date, several stem cell labeling protocols have been developed, contributing to a fast growing and promising field of stem cell imaging by MRI (magnetic resonance imaging). Most of these methods utilize iron oxide nanoparticles (MION, SPIO, USPIO, VSIOP) for cell labeling, which provide negative (dark) signal effec…
According to density functional theory of first-principles calculations theory, we systematically study the electronic structures, magnetisms and stabilities of transition metal (TM = V, Cr, Mn) doped MoS2 single-layers. The results show that V-and Mn-monodoped systems each have magnetism and the magnetic moment mainl…
The enhancement in cancer chemotherapy through incorporation into solid lipid nanoparticles (SLN) drug delivery system carries a lot of potential. Improving tumor diffusivity, improvement of body distribution, enhancing cellular uptake and inhibiting multidrug resistance mechanism are the main attributes. The availabi…
As opposed to culture on standard tissue-treated plastic, cell culture on three-dimensional scaffolds impedes additional challenges with respect to substrate preparation, cell seeding, culture maintenance, and analysis. We herewith present a general route for the culture of primary cells, differentiated cells, or stem…
The strength and elongation at break of a seam are very important characteristics of comfort clothing. Optimum seam strength must be durable enough to do our daily activities easily. Some parameters such as the type and count of the sewing yarn, the seam density, the size of the sewing needle, and type of stitch affec…
Self-assembly, the process by which building blocks spontaneously form an ordered structure, has become a key concept in soft matter science. In self-assembly, the physical properties of the building blocks determine the structure of the assembly. For example, the pitch and handedness of a self-assembled helix depend…
We applied first-principles calculations to study the relationship between the grain boundary energy (GBE) and grain boundary excess free volume (BFV) at the tilt grain boundaries in aluminum. GBE increased linearly as the grain BFV increased and the value of the proportionality constant between them, α, was 13.8 GPa…
Cosensitization by glutathione-protected Au25clusters on Ru complex, N719-sensitized TiO2photoelectrodes is demonstrated. Glutathione-protected Au25clusters showed no significant changes in properties after adsorption onto TiO2particles, as confirmed by optical absorption spectroscopy, transmission electron microscopy…
Poly(3,4-ethylenedioxythiophene), abbreviated PEDOT, is one of the most outstanding electroactive polymers, whose applications cover a wide range of fields from biomedicine to electronic components. In this work the physicochemical properties of nanoconstructs obtained by growing PEDOT chains over steel surfaces are i…
Corona discharge is a common phenomenon in power transmission lines external insulation, and it may cause serious defect if without effective detection. The ultraviolet (UV) imagery technology has been widely used to detect the corona discharge in industry in recent years, but some influence factors' functions are not…
