Biocomposites Based On Cellulose And Starch Modified Urea-Formaldehyde Resin: Hydrolytic, Thermal And Radiation Stability
(Wiley, 2019-04-10)
Two biocomposites based on cellulose (UFC) and starch modified urea formaldehyde (UFS) resin (F/U ratio of 0.8) were synthesized using the same procedure. The hydrolitical, thermal, and radiation stability of biocomposites ...
Hydrolytic, thermal and radiation stability of modified urea-formaldehyde composites: influence of montmorillonite particle size
(Elsevier, 2022-06-15)
Urea-formaldehyde (UF) composites with a formaldehyde/urea (FA/U) ratio = 0.8 and different particle sizes of montmorillonite (MMT), namely UF/KSF and UF/K10 were synthesized. The hydrolytic stability of modified UF ...
Nano-silica-based urea-formaldehide composite with some derivates of coumarin as formaldehyde scavenger: hydrolitycal and thermal stability
(Springer Nature, 2021-01-25)
The hydrolytic stability of two nano-SiO2-based UF composites with derivates of coumarin (names as K-1 and K-2) was investigated. K-1 is 3-nitro-4-(p-tolylamino)-2H-chromen-2-one and K-2: 4-((3-nitro-2-oxo-2H-chromen-4-y ...
Hydrolytic, thermal, and UV stability of urea-formaldehyde resin/thermally activated montmorillonite nanocomposites
(Wiley, 2020-09-16)
Urea-formaldehyde resin (F/U ratio of 0.8)/thermally activated montmorillonite (UF/ΔTK10) nanocomposite was synthesized. The hydrolytical, thermal, and UV radiation stability of UF/ΔTK10 nanocomposites are determined. UF ...
Hybrid materials based on rubber blend nanocomposites
(Wiley, 2019-08-15)
In this applicative work, two types of silica filler were used to increase the adhesion strength between steel and elastomeric hybrid materials based on chlorosulfonated polyethylene rubber (CSM) and polychloroprene rubber ...
Enhancement of the bandwidth of W-type glass optical fibers in the infrared wavelength region
(Elsevier, 2018-08-28)
Transmission characteristics (bandwidth and steady state loss) of multimode W-type glass optical fibers are investigated by solving the time-dependent power flow equation. Results show how the bandwidth in W-type glass ...
Influence of width of launch beam distribution and mode coupling on transmission characteristics of W-type plastic optical fibers
(IOP Science, 2021-07-16)
We show strong effects of width of the launch beam’s angular distribution on bandwidth and
mode coupling in W-type plastic optical fibers (POFs). In general, the broader this width, the
stronger the coupling and the lower ...
Calculation of the bandwidth of W-type photonic crystal fibers by time-dependent power flow equation
(Elsevier, 2018-06-30)
A multimode photonic crystal fiber with a solid-core takes the characteristic W-shaped index profile upon forming
an inner cladding layer with its own value of the effective refractive index corresponding to the distinct ...
Influence of mode coupling on three spatially multiplexed channels in multimode graded index plastic optical fibers
(IOP Science, 2020-10-27)
The influence of mode coupling on three-channel spatial division multiplexing capability in
multimode graded index plastic optical fibers is investigated by solving the power flow
equation. Our numerical results show ...
Spatial division multiplexing in nine-core graded index plastic optical fibers
(IOP Science, 2020-07-28)
We propose a spatial division multiplexing in a new designed multimode multicore graded index
plastic optical fiber with nine cores arranged in an octagonal array. The influence of mode
coupling on two-channel spatial ...
