SnO2/graphene composite with superior cycle performance and high reversible capacity was prepared by a one-step microwave-hydrothermal method using a microwave reaction system. The SnO2/graphene composite was characterized by X-ray diffraction, thermogravimetric analysis, Fourier-transform infrared spectroscopy, Raman spectroscopy, scanning electron microscope, X-ray photoelectron spectroscopy,...
Nitrogen-doped carbon microspheres (NCSs) were fabricated via a simple, fast and energy-saving microwave-assisted method followed by thermal treatment under an ammonia atmosphere. NCSs thermally treated at different temperatures were investigated as anode materials for lithium ion batteries (LIBs). The results show that NCSs treated at 900 °C exhibit a maximum reversible capacity of 816 mA h g(...
به سبب بهبود خواص فیزیکی و مکانیکی مانند پایداری حرارتی، استحکام کششی و ممانعت در برابر نفوذ، نسبت به پلیمر خالص، تمایل زیادی برای استفاده از نانوکامپوزیت های پلیمر و نانوخاک رس وجود دارد. در چند دهه گذشته، کارایی نانوکامپوزیت های تهیه شده برپایه پلی اتیلن و نانوخاک رس در صنایع حمل و نقل، سیم و کابل، بسته بندی مواد غذایی و ساختمان منجر به استفاده گسترده از آنها شده است. البته ماهیت آب دوست نانو...
Homogeneous VO2 (B) nanorods approximately 100 nm in width and 1–2 mm in length have been fabricated via the hydrothermal process, and are then transformed into irregularly shaped V2O5 nanoparticles of several hundreds nanometers large and 20–30 nm thick after annealing the precursor material at 500 C for 30 min. Both the V2O5 sheet-like nanoparticles and VO2 (B) nanorods were tested as active ...
In this work, a one-dimensional Co3O4@TiO2 core-shell electrode material with superior electrochemical performance is fabricated by a convenient and controllable route. The approach involves two main steps: the homogeneous deposition of polydopamine and TiO2 layers in sequence on the cobalt coordination polymer and the thermal decomposition of the polymer matrix. The as-prepared electrode mater...
DOI: 10.1002/aenm.201500174 The continuous pulverization of alloy anodes during repeated sodiation/desodiation cycles is the major reason for the faster capacity decay. However, if these elements can form a compound (such as Sn 4 P 3 ) after each Na extraction, the pulverization of these elements can be partially repaired and the accumulation of pulverization can be terminated. Therefore, we ca...
Polylactic acid (PLA) is one of the most promising biopolymers often used as a raw material in 3D printing many industrial areas. It has good mechanical properties, characterized by high strength and stiffness, but unfortunately, it some disadvantages; brittleness, other slow crystallization. Amounts 1–5% SEBS (styrene-ethylene-butylene-styrene) thermoplastic elastomer were blended into PLA the...
Introduction & Objective: Benzene is a light yellow liquid with aromatic odor and has effects to human body. The main and dangerous health effect of chronic exposure to benzene in workplace is hematopoetic system disease or blood cancer that it's primarily clinical figures are anemia, leucopenia, thrombocytopenia. The objective of this study was evaluation of benzene exposure by analysis of uri...
