In this paper, the effects of alignment, pH, surfactant and solvent on heat transfer nanofluids containing Fe2O3 CuO nanoparticles are studied analyzed. The microscope images show that could form some kind alignment spontaneously in water even without external magnetic field. With addition field, is strengthened. water, particle agglomeration to larger size occurs easily, which makes directional much faster easier. Ethylene glycol chemical sodium dodecyl benzene sulfonate, NaDDBS separate...
We report fast synthesis of bamboo-type TiO2 nanotube arrays via anodization Ti in nonhazardous electrolyte under alternating voltage condition for applications as photoanodes high-efficiency dye-sensitized solar cells (DSSCs). Formation mechanism nanotubes is also explored. The low-voltage step reduces pH and ion-diffusion gradient inside induces formation bamboo ridges on outer tube walls when a second high-voltage conducted. Ridge spacing length can be facilely tuned by adjusting time...
A first electrolyte gated polymer light-emitting transistor (PLET) is reported with high performances up to 4000 cd m−2 brightness and 2.3% external quantum efficiency. This novel (PE) PLET characterized interpreted as reversible electrochemical doping of under the assistance PE at their interface, leading current density electroluminescence modulation by applied gate potential. As a service our authors readers, this journal provides supporting information supplied authors. Such materials...
LiMn2O4 suffers from severe capacity degradation when used as a cathode material in rechargeable lithium-ion batteries, especially cycled at high rates and elevated temperatures. To enhance its high-rate electrochemical performance temperature (55 degrees C), we use atomic layer deposition (ALD) to deposit ultrathin highly conformal Al2O3 coatings (as thin 0.72 nm) onto micron-sized nano-sized with precise thickness-control scale. All ALD-modified electrodes exhibit significantly improved...
In the present work, we use chemical exfoliation to fabricate ultrathin two-dimensional anatase TiO2 nanosheets (NSs) for application as photoanode materials in dye-sensitized solar cells. For first time, colloidal Ti0.91O2 NSs are synthesized via of a layered precursor (HxTi2–x/4□x/4O4·H2O; □: vacancy, x = 0.7) through ion exchange with tetrabutylammonium (TBA+) cations. The as-prepared well-dispersed and lateral size up few micrometers. Subsequent acid treatment induces reassemble...
Energy relay dyes based on GUMBOS displayed improved characteristics in comparison to respective parent including solubility and solar efficiency.
Low-cost and low-voltage active matrix displays were fabricated by simply patterning gate electrode arrays on a polymer electrolyte (PE)-coated light-emitting diode (PLED). Structurally, PE capacitor seamlessly stacked PLED sharing common Al:LiF composite (PEC|PLED). This monolithic integrated organic optoelectronic device was characterized interpreted as the tunable work function (surface potential) because of perturbation accumulated ions PEC charging discharging. The modulation electron...
We report vertical electrolyte-gated red, green, and blue phosphorescent small-molecule organic light-emitting diodes (OLED), in which light emission was modified by tuning the electron injection via electrochemical doping of layer 4,4-bis(N-carbazolyl)-1,1-biphenyl (CBP) under assistance a polymer electrolyte. These devices comprise an electrolyte capacitor on top conventional OLED, with interfacial contact between CBP OLEDs achieved through porous cathode. exhibit tunable luminance 0.1 10...
