Films formed by blending of two polymers usually have modified physical and mechanical properties compared to films made the individual components. Our preliminary studies indicated that incorporation chitosan in polyethylene oxide (PEO) may provide additional functionality PEO decrease their tendency spherulitic crystallization. The objective this study was determine correlation between chitosan/PEO weight ratio physical, mechanical, antibacterial corresponding films. with ratios from 100/0...
Nonwoven fiber mats of chitosan with potential applications in air and water filtration were successfully made by electrospinning poly(ethyleneoxide) (PEO) blend solutions. Electrospinning pure was hindered its limited solubility aqueous acids high degree inter- intrachain hydrogen bonding. Nanometer-sized fibers diameter as low 80 ± 35 nm without bead defects molecular weight chitosan/PEO (95:5) blends. Fiber formation characterized shape size found to be strongly governed the polymer...
Steel slag is a solid waste product generated during the carbonation stage of steelmaking. It has high levels heavy metals and substantial amounts free calcium magnesium oxide, making it unsuitable for use as cement material. Furthermore, disposal steel in landfills requires many resources can seriously contaminate surrounding environment. One method reducing its negative environmental impact carbonation, which involves reacting with carbon dioxide to form stable minerals. However,...
The magnesium oxysulfate (MOS) cement has problems of short setting time, poor water resistance, and volume instability. This paper investigates the potential steel slag (SS) to modify properties microstructure MOS prepared by desulfurization byproducts (MDBs). results showed that SS delayed restrained shrinkage, improved resistance cement. hydration products were fibrous 318 phase (3Mg(OH)2•MgSO4•8H2O), lamellar Mg(OH)2, MgCO3. addition increased pH decreased overall reaction rate amount...
In order to solve the problems of large-scale resource utilization iron ore waste rock, rock is used prepare green building materials, but it needs be further promoted for use in high-strength concrete. this study, concrete was prepared using as coarse and fine aggregates combined with solid waste-based cementitious materials. The mechanical durability properties washed unwashed two types were compared, including compressive strength, freeze resistance, chloride ion carbonation pore...
Recently, integrated mineral carbonation for CO2 sequestration has received significant attention due to the high potential commercialization towards mitigating climate change. This review compiles work conducted by various researchers over last few years on processes in mining industry, which use ultramafic mine wastes as feedstock carbonation. Here, we introduce basic concepts of including a brief description process routes and pre-treatment techniques. We discuss scope application,...
Previous works verified experimentally that interactions between vortex-induced vibration (VIV) and galloping may greatly improve the performance of piezoelectric wind energy harvesters (PWEHs) at low speeds. However, no mathematical model has been available to date predict responses or optimize structures PWEHs. In this paper, a distributed-parameter electromechanical coupling VIV-galloping interactive PWEH was derived then validated using two harvester prototypes. For first prototype,...
In this paper, we investigate the mean field games with $K$ classes of agents who are weakly coupled via empirical measure. The underlying dynamics representative is assumed to be a controlled nonlinear Markov process associated rather general integro-differential generators Lévy-Khintchine type (with variable coefficients). We show that measure-valued kinetic equations describing dynamic law large numbers limit for system number N solvable and their solutions represent 1/N-Nash equilibria...
