Electric heating properties of FexOy–C composites
Springer Science and Business Media LLC - Tập 6 - Trang 862-865 - 2021
Jorge Luis Hernández Morelos, Abigail Parra Parra, Pedro Antonio Márquez Aguilar, Marina Vlasova, Jesús Mario Colin de la Cruz
It has been established that during heat treatment of mixtures of waste activated sludge (WAS) and Fe2O3 under the conditions of oxygen deficiency at 800–1000 °C, reactive carbon, which initiates the reduction of Fe2O3 to Fe and the formation of C–FexOy mixtures, forms. Based on these compacted mixtures, having different electrical resistivity (from ~ 10–4 up to 10–1 Ω·m), it is possible to fabric...... hiện toàn bộ
Carbon Nanotube Fabric-Based Composites for Development of Multifunctional Structures
Springer Science and Business Media LLC - Tập 4 - Trang 3123-3132 - 2019
Michael B. Jakubinek, Yadienka Martinez-Rubi, Behnam Ashrafi, Nicholas Gumienny-Matsuo, Daesun Park, Hao Li, Stéphane Dénommée, Benoit Simard
Carbon nanotubes (CNTs) possess impressive properties along with low density. Integration of CNTs in the form of fabrics or other preformed assemblies simplifies their handling and allows for the higher CNT content needed to better leverage their properties in multifunctional structures. Here we describe production of non-woven CNT-polyurethane fabrics made from industrial-grade CNTs via a one-ste...... hiện toàn bộ
Optical design of perovskite solar cells for applications in monolithic tandem configuration with CuInSe2 bottom cells
Springer Science and Business Media LLC - Tập 3 - Trang 3111-3119 - 2018
Ramez H. Ahangharnejhad, Zhaoning Song, Adam H. Phillips, Suneth C. Watthage, Zahrah S. Almutawah, Dhurba R. Sapkota, Prakash Koirala, Robert W. Collins, Yanfa Yan, Michael J. Heben
Monolithic integrated thin film tandem solar cells consisting of a high bandgap perovskite top cell and a low bandgap thin film bottom cell are expected to reach higher power conversion efficiencies (PCEs) with lower manufacturing cost and environmental impacts than the market-dominant crystalline silicon photovoltaics. There have been several demonstrations of 4-terminal and 2-terminal perovskite...... hiện toàn bộ

Microstructural influence on piezoresponse and leakage current behavior of Na0.5Bi0.5TiO3 Thin Films
Springer Science and Business Media LLC - Tập 1 - Trang 2597-2602 - 2016
Kumaraswamy Miriyala, Ranjith Ramadurai
Sodium bismuth titanate (Na0.5Bi0.5TiO3: NBT) a lead free piezoelectric; exhibits promising features such that it could be an alternate to lead based piezoelectrics. In this work, we report the microstructural influence on piezoelectric and leakage current behavior of NBT thin films grown by pulsed laser ablation (PLD). Various microstructural features like coarse faceted grains and fine spherical...... hiện toàn bộ
Carboxylated Carbon Nanotubes/Polyethersulfone Hollow Fiber Mixed Matrix Membranes: Development and Characterization for Enhanced Gas Separation Performance
Springer Science and Business Media LLC - Tập 3 - Trang 3103-3109 - 2018
Akshay Modi, Surendra Kumar Verma, Jayesh Bellare
Carboxylated carbon nanotubes (C or cCNTs) were incorporated in polyethersulfone hollow fiber membranes (P HFMs) to improve the gas separation performance, i.e., pure gas permeability and ideal gas selectivity. The developed CP HFMs showed the remarkable improvement in thermal stability and mechanical strength as compared to that of the pristine P HFMs. The pure gas permeability of CO2, CH4, O2, a...... hiện toàn bộ
Enhanced Coercivity in BiFeO3/SrRuO3 heterostructures
Springer Science and Business Media LLC - Tập 1 - Trang 597-602 - 2016
Srinivasa Rao Singamaneni, J. T. Prater, J. Narayan
Transition metal oxide thin film heterostructures have garnered increasing research interest in the last decade due to their multifunctional properties, such as ferromagnetism and ferroelectricity, which may be utilized in next generation device applications. Many previous works reported on the deposition of such structures on oxide substrates such as SrTiO3, which are not compatible with CMOS app...... hiện toàn bộ
Investigation of BMI-PF6 Ionic Liquid/Graphite Interface Using Frequency Modulation Atomic Force Microscopy
Springer Science and Business Media LLC - Tập 3 - Trang 2725-2733 - 2018
Harshal P. Mungse, Takashi Ichii, Toru Utsunomiya, Hiroyuki Sugimura
Structural analysis on interfaces between ionic liquids (ILs) and solid substrates is an important study for not only the basic fundamental aspects but also many technological processes. In the present work, we utilized frequency modulation atomic force microscopy (FM-AFM) based on a quartz tuning fork sensor to elucidate the structure of interface between 1-butyl-3-methylimidazolium hexafluoropho...... hiện toàn bộ

Ion Beam Synthesis of Doped Nanocrystals of Si1-xGex Alloys Embedded in SiO2
Springer Science and Business Media LLC - Tập 2 - Trang 975-980 - 2017
D. Muller, D. Mathiot, G. Ferblantier, A. Chelouche, G. Schmerber
As an extension of our previous proving that ion beam synthesis is an efficient route to form doped silicon nanocrystals (nc’s) [1, 2], we show here that ion beam synthesis, by co-implantion of the dopant and of the constituents of the alloy, followed by a single high temperature anneal, is also a convenient way to grow more complex structures, such as As doped nc’s of Si1-xGex alloys.
