Pal[10] et al use a simple device architecture based on a poly(3,4-ethylendioxythiophene) : poly(styrenesulfonate) (PEDOT:PSS)-coated indium tin oxide anode and a LiF/Al cathode to assess the effects of shell thickness on the properties of light-emitting diodes (LEDs) comprising CdSe/CdS core/shell nanocrystal quantum dots (NQDs) as the emitting layer (Figure 1).
(B) (A) Their simple device architecture comprises a NQD active layer in between a poly(3,4-ethylendioxythiophene):poly-(styrenesulfonate) (PEDOT:PSS)-coated indium tin oxide (ITO) anode and a LiF/Al cathode (Figure 1A).
The EL spectra were recorded with a spectrometer (Ocean Optics, Inc.) coupled to an optical fiber.

Reliability theory equation of long-term performance prediction of GFRP bars Trejo et al (2009) introduced exposure factor λ in prediction model (4) to make the model more flexible to fit the experimental data, which was modified as follows
Numerical examples Trejo et al.(2009) exposed GFRP bars to seven years outdoor exposure with nearly no stress which is one of the few long-term research results.
Trejo et al reported a range of diffusion coefficient for the different GFRP bars from 4.47×10-10 in2/sec (2.88×10-13 m2/sec) to 2.39×10-9 in2/sec (1.54×10-12 m2/sec), with a mean value of 1.38×10-9 in2/sec (8.9×10-13 m2/sec).
From the literature (Trejo al 2009) the tensile strength mean value was 537.21MPa and standard deviation was 75.23 MPa after 7 years.

Table 2 shows some important infrared absorption bands characteristic for jute fiber from the work of Rana et al [31].
According to Khan et al [34], this O-H stretching may be associated with absorbed water as well as alcohols found in cellulose, hemicellulose, lignin, extractives and carboxylic acids.
According to Ibrahim et al [33], bands in these regions could be attributed to vibration of the alpha-keto carbonyl for cellulose.

After the grinding process, the pastes (barbotines) were placed on a tray and then taken into an Odontobras, EL-1.6 model heating chamber, 2200 Watts, 130ºC temperature, for five hours.
Once pressed, the specimens were placed into the Odontobras EL-1.6 2200 Watts heating chamber, at 110ºC for 24 hours.
