Fabrication and Investigation of Graphite-Flake-Composite-Based Non-Invasive Flex Multi-Functional Force, Acceleration, and Thermal Sensor
منشور في 2023"…Sensor impedance was measured from DC to 200 kHz at up to 20 gf, 20 m/s2, and 26–60 °C. Sensor resistance and impedance to stretching force and acceleration at DC and 200 Hz rose 2.4- and 2.6-fold and 2.01- and 2.06-fold, respectively. …"

The Optical and Electrical Properties of Low Density Polyethylene Films in CuSo4 Solution
منشور في 2005"…The results of this study show that: (1) Direct and indirect optical transitions exist, (2) Direct and indirect energy gaps increase as the exposure time increases, (3) The Urbach energy band tail decreases as time increases, (4) The d.c. conductivity decreases, while the dielectric constant increases as time increases. …"

Synthesis and electrochemical properties of nickel oxide/carbon nanofiber composites
منشور في 2014"…These electrospun fibers were stabilized for 2 h at 200 °C and then carbonized at 800 °C for 5 h. Composites were prepared by depositing Ni(OH)2 on the carbon nanofibers (CNFs) and calcining them at different temperatures. …"

Hydrogen Production via Ethanol Decomposition over Bimetallic Catalyst
منشور في 2016"…Ethanol decomposition over bimetallic CuCo were conducted using in situ diffuse reflectance infrared fourier transform spectroscopy (DRIFT) study under N2 flow at different temperatures (50, 100, 200, 300, 400°C). Temperature-time profile of CuCo shows an increase in combustion temperature with increase in fuel ratio with maximum temperature at φ = 1 (stoichiometric ratio) and after that it decreases. …"

Thermal behavior and post-heating fracture characteristics of polypropylene microfiber-reinforced geopolymer binders
منشور في 2022"…Geopolymer binders with different fiber contents including 0%, 0.05%, 0.1%, and 0.2% by fly ash weight were prepared and exposed to elevated temperatures of 200 °C, 400 °C, and 600 °C. The effect of fiber reinforcement on the mechanical strengths of unheated binders, residual fracture characteristics of heat-damaged binders, microstructure deterioration, and thermal properties of geopolymer specimens were investigated. …"
