Waste disposal becomes a crucial issue for both the environment and the economy. One of the solutions for waste disposal is to utilize waste materials in concrete production. Nowadays, alkali activated concrete takes attention since waste materials (fly ash and ground granulated blast furnace slag) are utilized instea…
The energy crisis and environmental pollution from excessive use of traditional fossil fuel have been prompting a number of researchers and institutes to develop new technology, emerging mat-erials, and potential applications for green, sustainable and renewable power source. There is a rich source of energy in the en…
The precipitates in Q460FRW fire-resistant steel under equilibrium state were calculated using Thermo-Calc thermodynamic software. The evolutions of matrix and precipitates in this steel before and after high temperature exposure at 600℃ were experimentally observed and analyzed using optical microscopy(OM), scanning…
Nickel-rich ternary materials for lithium ion batteries are the preferred cathode materials for automotive power batteries at present and in the future, due to their low cost, high energy density, high reversible capacity and environmental friendliness. On the basis of reviewing the crystal structure and electrochemic…
The application of high-strength aluminum alloy on the vehicle body will be the development trend of automobile lightweight in the future.The effects of two-step aging on the microstructure and properties of high-strength aluminum alloys for automobile were investigated by tensile tests, electrical conductivity, and t…
A hydrothermal method was employed to synthetise NaV6O15 nanobelts, then nanobelts were annealed in air, the nanorods (NRs) were obtained at 350℃, which possess a length and diameter of 500nm and 100nm, respectively. NaV6O15 NRs as the electrode of supercapacitor exhibit significantly improved electrochemical performa…
With the rapid development and application of nuclear energy and technology, a large number of radioactive wastewater was produced, which caused potential pollution to the ecological environment. The research on radioactive wastewater treatment is of great significance to environmental protection. Graphene oxide and i…
Background: The development of biocompatible nanocarriers that can efficiently encapsulate and deliver anticancer drug to the tumor site and provide controlled release of cargos in response to the specific cues for cancer therapy is of great significance. Methods: In this work, dual pH/redox-responsive fabrication of…
Abstract Herein we report a crystalline molecular rotor with rotationally modulated triplet emission that displays macroscopic dynamics in the form of crystal moving and/or jumping, also known as salient effects. Molecular rotor 2 with a central 1,4‐diethynyl‐2,3‐difluorophenylene rotator linked to two gold(I) nodes,…
This work reports a novel type of reversible shape memory polymers (RSMPs) from commercially available thermoplastic polyolefin elastomers (POEs). Two RSMPs based on Dow Chemical’s POE Engage 8003, Engage 8137, Engage 8180, and olefin block copolymer elastomer Infuse 9007 were prepared by simple blending of the commer…
Abstract Silver nanoparticles have been successfully synthesized using a chemical reduction method at room temperature using glucose as a reducing agent, silver nitrate as a source of nitrate, polyvinyl alcohol (PVA) as a stabilizing agent. The purpose of this research was to determine the effect of the mole ratio of…
In this work, density functional theory (DFT) calculations at the M06-2X/6-31+G* level are performed to the adsorption of COn (n=1, 2) and HnX (n=2, 3 and X=O, N)molecules onto pristine as well as Al- and Ga-doped B12N12 nanocages. We study the effect of Al- and Ga-doped on the sensing properties of B12N12 nanocages.…
Abstract The article presents the developed rationalization technique of composite steel reinforced concrete sections with steel open section beams based on the criterion of equal strength of the section elements that are extremely distant from the neutral line. Algorithms for search for geometric parameters of a comp…
Nitrogen-vacancy centers in diamond are promising as sensitive vector magnetometers, quantum repeaters, and qubits, but realizing this potential has been limited by the diamond material itself. Here a comprehensive study addresses creation of nitrogen-vacancy centers, balancing the impact of irradiation and annealing…
The energetics of rotation around single bonds (torsions) is a key determinant of the three-dimensional shape that druglike molecules adopt in solution, the solid state, and in different biological environments, which in turn defines their unique physical and pharmacological properties. Therefore, accurate characteriz…
The concept, design strategy and self-assembly of chiral supra-amphiphiles were summarized in this review article.
The pore structure of expanded graphite (EG) including pore volume, pore size distribution and surface area is investigated by mercury porosimetry, nitrogen adsorption and SEM. Also, the diffusion of silicone oil molecules as macromolecules with different molecular weights into EG pores is studied. Various EG samples…
In the laboratory experiment described here, students synthesize silver nanostructures (AgNS) with different shapes and sizes to elucidate the shape- and size-dependent optical properties of nanostructured materials. Students also develop understanding of some thermodynamic and kinetic aspects of the synthesis process…
Recently, a new novel nonthermal technology being investigated is Hydrodynamic Cavitation (HC), which can be used for sterilization of liquid foods such as liquid beverages (water, juices, milk), homogenization, emulsification, enhanced extraction, with minimal loss of bioactive compounds. This novel technology has po…
The jet characteristics of bubbles near mixed boundaries have been the focus of research in many fields. As the associated parameters are complicated, relatively few reports have been published. In this paper, a numerical model is established by considering the influence of the free surface and a mutual vertical wall…
