A successful research strategy lays out a path with small steps that allows for changes in direction along the way. The “SCO” flowchart for experimenters (Figure 1) is a prime example of such a template for success. Its tried-and-true core is screening (“S”), characterization (“C”) and optimization (“O”). One last, but perhaps most important, step is added: Confirmation. Let’s dive into the SCO strategy for researchers and find out what makes it work so well. The starting point is the Screening design. Screening designs provide a broad, but shallow, search for previously unknown process factors. Use a two-level factorial design to quickly identify variables that affect the responses. TIP – to keep the number of runs lower, don’t bother screening factors that are already known to affect your responses! Newly discovered factors—the “vital few” will carry forward into the next phase of experimentation, with the “trivial many” being set aside. By using medium-resolution (Res IV) designs, you can estimate the main effects cleanly—their effects unbiased by hidden interactions. Moving ahead to Characterization with the vital-few screened factors plus the big one(s) you originally set aside, the identification of two-factor interactions becomes the goal. This necessitates a high-resolution design (Res V or better). Be sure to add center points at this stage so you can check for curvature (non-linearity). If curvature is NOT significant, then your mission is nearly complete—all that remains is Confirmation! If curvature does emerge as being significant and important, then move on to Optimization using response surface methods (RSM). The beauty of RSM is that you can use contour and 3D surface maps to see where each response peaks. Also, via numerical optimization tools, you can pinpoint the setup of factors producing the most desirable outcome for multiple responses. Graphical optimization via overlay plots lays out a compelling visual of the sweet spot—the window where all specifications can be achieved. Last, but not least, comes Confirmation. Decide if you want to confirm one specific “optimal” location in the design space, or if your interest is in verifying a broader area.

Three poly (lactic acid) (PLA) resins with molecular weight (Mw) equal to 55 (3251D), 125 (L105) and 163 (LX175) kg/mol were characterized in terms of capillary viscosity, mechanical and thermal properties and used to produce blown films. The effect of temperature, extrusion rate, stretching (TUR) and blow-up (BUR) ratios were evaluated to determine the optimum processing conditions for blown films based on the bubble stability and to determine their final tensile properties. As expected, the processing temperature was the most critical parameter on the film stability. The lower Mw PLA showed limited processing stability. Stable conditions were found at higher temperature (200°C) for higher Mw. These results correlate with the PLA viscosity (melt strength). Finally, the PLA film tensile strength (TS) strongly depended on their processability. For example, 3251D and L105 required high stretching (TUR = 3.4 and 7) for maximum TS (30 and 64 MPa) with a low blow-up ratio (BUR = 1.02–1.15). However, a moderate increase in BUR (10% at TUR = 3) led to a substantial drop in TS (from 29 MPa to 21 MPa for PLA 3251D and 44 MPa–34 MPa for L105). Overall, LX175 was the most interesting resin with 49 MPa TS which was independent of the BUR and TUR used in this investigation.

How nanoparticle type and content affect polybutylene succinate (PBS) properties were investigated by varying nanoclay and calcium carbonate nanoparticles (nanoCaCO3) from 0 to 15 wt%. PBS/nanoparticle composites were prepared by compounding with a co-rotating twin-screw extruder and forming them with a compression molding machine. Their mechanical properties, filler dispersion, crystallinity, and permeability were evaluated using tensile testing, energy dispersive X-ray analysis, transmission electron microscopy, differential scanning calorimetry, X-ray diffraction, and water vapor and gas permeability measurements. The results showed that adding nanoclay and nanoCaCO3 enhanced the PBS stiffness. In comparison to neat PBS, the highest tensile moduli were 46% higher at 15 wt% nanoclay and 30% higher at 15 wt% nanoCaCO3. The ultimate tensile strength (UTS) for the PBS/nanoclay composites tended to decrease as the nanoclay content increased. Nanoclay dispersion was poor in composites containing more than 5 wt% nanoclay. Surface treating the nanoCaCO3 particles with a fatty acid resulted in similar UTS values and reduced the elongation at break to 15% from 225% for the neat PBS. The decrease in ductility resulted from PBS chain scission. The nanoclay and nanoCaCO3 at low content enhanced the PBS crystallization. The nanoplatelet-shaped nanoclay led to greater agglomeration than the cubic-shaped nanoCaCO3, but the nanoclay was more effective than the nanoCaCO3. The water vapor barrier properties improved with the added nanoclay, with about a 52% reduction in water vapor permeability as compared to neat PBS. The water vapor and oxygen barrier properties of nanoclay were more effective than the nanoCaCO3.

This study focuses on the development of low-density polyethylene matrix nanocomposite films for food packaging industry and aims at improving low-density polyethylene oxygen barrier properties while maintaining other relevant characteristics, such as processability, easy post-processing, optical and mechanical properties. low-density polyethylene nanocomposites, with 1 and 2.5 wt.% nanoclay (NC) and also compatibilized with 5 wt.% polyethylene grafted with maleic anhydride (PE-g-MA), were prepared and used to produce blown films. The nanocomposites were characterized in terms of their morphology, thermal, rheological, mechanical, barrier and optical properties, through scanning electron microscopy (SEM), X-ray diffraction (XRD), differential scanning calorimetry (DSC), rheological measurements, tensile tests, water vapor transmission, oxygen permeability tests and spectrophotometry. The results demonstrated good NC dispersion in the polymer matrix and decreased oxygen permeability in the compatibilized nanocomposite films. All the other properties did not significantly change when compared to neat low-density polyethylene. Overall, the film properties were improved with the added nanoclay and PE-g-MA and, have potential for food packaging.

Roll-coating process plays an important role in many industries for its practical applications such as paint, PVC coated fabrics and plastic industries. There are several roll-to-roll coating methods including forward and reverse roll-coating. However, the roll-over-web coating study of the Rabinowitsch model is presented in this paper. The flow equations for the problem are developed and converted into dimensionless form with the help of dimensionless variables and then finally simplified by a well-known lubrication approximation theory. We employ the regular perturbation technique to get analytical expressions for velocity, pressure, and pressure gradient. Engineering quantities such as power input function and roll-separating force are calculated by Runge-Kutta method. The dimensionless Rabinowitsch parameter effect on velocity, pressure, pressure gradient, load-carrying force, and power input are shown graphically. It is interesting to note that for the shear thickening case, the Rabinowitsch model predicts 35% higher pressure, while in the shear thinning case it predicts 29% less pressure in the nip region when compared to the Newtonian model. The force and power show a decreasing trend on increasing the dimensionless Rabinowitsch parameter a. Moreover, the separation point shifts right of its Newtonian value when fluid behaves like shear thickening and volumetric flow rate increases which causes the coating thickness to increase.

The primary objective of this research paper is to control the material and process defects in polymer melt extrusion film casting (EFC) process for linear chain architecture polyethylene (PE) resins through polymer blending methodology. Extrusion film casting is a well-known industrially important manufacturing process that is used to manufacture thousands of tons of polymer/plastic films/sheets and coated products. In this research, the necking defect in an EFC process has been studied experimentally for a linear low density polyethylene (LLDPE) resin and attempts have been made to control its necking by blending in a long chain branched (LCB) low density polyethylene (LDPE) resin. The blending methodology is based on the understanding that a LDPE resin displays enhanced resistance to necking as compared to the LLDPE resin. It is found that added LDPE resin enhances necking resistance for the primary LLDPE resin. Further, as the LDPE concentration increases in the blend formulation, the necking is further reduced as compared to pure LLDPE. Analogous to past studies on EFC of linear and long chain branched architecture containing PEs, it is observed that as the LDPE is increased in the blend formulations, the formulations displayed enhanced melt elasticity and extensional strain hardening in rheological studies. It is concluded from this study that polyethylene resins having linear chain architecture can be made amenable to enhanced resistance to necking using appropriate amount of a long chain branched resins. Finally, process defects such as the draw resonance onset could be shifted to higher draw ratios as the LDPE level is increased in the LLDPE-LDPE blend formulation.

Die 1930er-Jahre gelten als das populistische Jahrzehnt Hollywoods. Regisseure wie Frank Capra, Leo McCarey und John Ford entwerfen in ihren Werken Szenarien geglückter oder gescheiterter politischer Repräsentation, in denen sich demokratische Ideale mit politischer Theologie und amerikanischem Exzeptionalismus verbinden. Die Szenographie dieser Filme hat sich tief in das kulturelle Gedächtnis der USA eingeschrieben und prägt die politische Inszenierung von Repräsentation bis heute. Johannes Pause liest die damals entstandene Bildsprache als eine Typologie populistischer Repräsentation neu und nutzt sie als Folie, um aktuelle politische Tendenzen zu analysieren.
