Track-etched polymer membranes are used to realize low-voltage electroosmotic (EO) pumps. The nanopores in polycarbonate (PC) and polyethylene terephthalate (PET) membranes were fabricated by the track-etching technique, the pore diameter was controlled in the range of 100 to 250 nm by adjusting the etching time. The results show that these EO pumps can provide high flow rates at low applied vo...

The experimental study deals with Hybrid fibre reinforced concrete with the use of (Polypropylene and Recycled polyethylene terephthalate RPET). The M40 grade concrete used was designed by using IS10262-2009 code. The steel fibre and synthetic fibre were added at the volume fractions up to 0.5%. Test results showed that the fibres, when used in a hybrid form, could result in superior composite ...

In this study, based on ion-current rectification in the conically shaped nanochannel embedded in polyethylene terephthalate (PET) membrane, we have selectively discriminated three small biomolecules. Because three positive biomolecules (Hoechst 33342, Propidium and Bupivacaine) have different hydrophobicities, their interactions with inside wall of the conical nanochannel are different and the...

Metalworking-fluids (MWFs) perform essential functions to metal-products manufacturing industry. MWFs also have inherent environmental and health liabilities associated to industry. These liabilities viewed as opportunity to reevaluate the functionality of MWFs and improve profitability of operations. Several problems appeared in using of MWFs including biodegradation of constituents. The objec...

Having established commercial applications of hot compacted products based on polypropylene we are now actively exploring other polymers to ascertain whether these can provide practical alternatives and in particular improvements in terms of certain physical properties. We have selected polyethylene (PE), poly (ethylene terephthalate) (PET) and nylon for comparative trials. For these materials,...

Abstract In this article, the consistent pattern of mass transfer in process drying granular polyethylene terephthalate (PET), polycaproamide (PCA), and polyamide 66 (PA 66) were studied. A modified quasi-stationary method was used to analyze data. The characteristic time hydrodynamic intensity index obtained based on experimental Some features water sorption desorption by fiber-forming polymers

Abstract In this study, we evaluate the thermal and mechanical properties of materials based on polypropylene (PP), high-density polyethylene (HDPE), terephthalate (PET) using thermogravimetric analysis impulse excitation technique. The results show that even if melted input material together with pressure ~4 MPa was used to produce samples, can find small cavities around sand grains in samples...

The key-objective of this opinion paper is to highlight how and why (enzymatic) reactive extrusion, i.e., REx, expected reduce the plastic pollution particularly in oceans. As green (solvent-free) continuous innovative process, REx represents such an efficient tunable industrial tool either for producing biodegradable biosourced plastics, so called bioplastics, or enzymatically recycling bottle...

Poly (3,4-ethylenedioxythiophene)-poly (styrenesulfonate) (PEDOT:PSS) was coated on flexible polyethylene terephthalate (PET) substrate using slot die on a roll-to-roll (R2R) system under different web tensions. The electrical resistance, the standard deviation of the recorded resistance and surface roughness of the coating under different tensions were analyzed. Based on these data an optimum ...
