Bismuth ferrite, BiFeO3, is the most investigated multiferroic material in which ferroelectricity coexists with an antiferromagnetic order at room temperature. The crystalline structure of BiFeO3 is well recognized for monocrystals as well as for polycrystalline materials or thin films. BiFeO3 is reported to have a rh…
Ionically crosslinked chitosan membranes were prepared and their density was determined using modified pycnometer method. High‑molecular compound: sodium alginate (NaAlg) and low‑molecular compounds: pentasodium tripolyphosphate (TPP) and trisodium citrate (CIT) were used as ionic crosslinkers of chitosan. As a refere…

We theoretically simulate one-photon and two-photon absorption spectra for monolayer and bilayer graphene employing the second-order perturbation theory of the electron-photon interaction. The tight-binding model is used to describe the band structure of graphene. The results show that one-photon absorption coefficien…
Utilizing insulator-metal phase transition of vanadium dioxide thin film, we propose a thermally controlled terahertz modulator based on metamaterial, and research the transmission characteristics and temperature tunable characteristics of phase transition in metamaterials in THz wave band. While the incident THz wave…

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…
