in production of tissue paper, the adhesion of a liquid adhesive creping aid, compound polymer, as creping aids on the yankee dryer surface was investigated. a compound polymer was prepared based on mixing ratio of poly (amideamine)-epichlorohydrin resin (pae) as an adhesive agent, polyvinyl alcohol (pva) as a modifier agent, and cationic fatty acid (cfa) and ethylene glycol (eg) as release age...

It is widely appreciated that an attractive polymer-substrate interaction can slow relaxation in thin supported polymer films and polymer nanocomposites. Recent measurements and simulations on nancomposites have indicated that this slowing of polymer dynamics occurs more strongly near a highly attractive particle surface where a "bound" layer having a much lower mobility can form, strongly infl...

Polyacrylonitril (PAN)-supported chitosan (CS) nanocomposite membranes were prepared by cross-linking the CS with 3-aminopropyl-triethoxysilane (APTEOS) via sol-gel method. Pervaporative performances of the CS-SiO2/PAN membrane for dehydration of aqueous alcohol solutions were investigated. From SEM cross-sectional images of the membrane, the spongy pores and the finger-like pores we...

In situ fracture study of a Cu/Al composite laminate was discussed via the observation of scanning electron microscope (SEM). The experimental test was carried out by a modified miniature tensile device. With the aid of the SEM’s sample stage and a wedge block, the profile morphology of the specimen was observed. The substrate layer (1060 aluminum) and the plate layer (C11000 copper) of the spe...

In this work we demonstrate a growth process for obtaining high optical emission efficiency InAs/GaAs(001) quantum dots (QD) formed at short distance to the interface with the GaAs substrate. In particular, after an initial exposure of the substrate surface to long times of atomic hydrogen flux (tH up to 45 min) followed by a posterior growth of a GaAs buffer layer by atomic layer molecular bea...

DC transfer characteristic measurements have been carried out on one n-channel Si/SiGe MODFETs with a MOS gate at three different substrate biases. For our layer structure, electrons are supplied into the strained Si quantum well (QW) from the top heavily doped layer and below the QW is non-intentionally doped (setback). Here, we numerically studied the setback layer, for which the doping can b...

By studying the adsorption of CO on up to 30 layers of Pt deposited on Ru(0001) the influence of surface strain on the adsorption energy has been disentangled from the residual chemical interaction with the substrate. While the electronic influence of the substrate has largely vanished for three Pt layers, the effect of surface strain due to the 2.5% lattice mismatch of Pt and Ru remains initia...

Using molecular dynamics simulation, we have shown that multilayer graphene nanoribbons located on the flat surface of h-BN crystal (on substrate) delaminate due to thermal activation into a parquet single-layer substrate. The delamination requires overcoming energy barrier associated with initial shift its upper layer. After barrier, proceeds spontaneously release energy. value this has been e...
