Poloxamer 407 (POL) is widely used as a thermosensitive hydrogel for intravesical instillation. When POL hydrogel is instilled in the bladder, several problems, including urinary tract obstruction, are observed. To overcome this problem, a POL-based floating hydrogel (PFH) system was developed. Sodium bicarbonate (BC) was used as a floating agent. PFH was optimized using a central composite design with two independent variables (X 1 [POL concentration, 42.43%] and X 2 [BC concentration, 5.23%]) and three response factors (Y 1 [floating time, 240.33 s], Y 2 [duration time, 270 min], and Y 3 [viscosity, 110.39 Pa. s]). In gel erosion and drug-release studies in vitro, the remaining PFH fraction decreased exponentially with time, while gemcitabine release was biphasic and surface erosion-controlled. A plot of drug release versus gel erosion showed good linearity. Visual observation for floating, gel duration, and dye release supported the time-course behaviors of the PFH, indicating its usefulness in intravesical instillation.

“…is shows the removal of few materials from the mild steel surface, which supports the findings provided in Figure 12. Low-viscosity oil may assist in heat reduction in the interface and debris washing [41,42]. On the other hand, Figure 14 exhibits the surface morphology of the worn surface of mild steel lubricated by 40% synthetic oil and 60% canola oil.…”

New lubricants based on vegetable oil were developed in this study. Different blends of canola oil mixed with fully synthetic two stock engine oils were developed (0, 20%, 40%, 60%, and 80% of synthetic oil). The viscosity of the prepared blends was determined at different temperatures (20°C–80°C). Tribological experiments were conducted to investigate the effect of the newly developed oil on the wear characteristics of mild steel material compared with stainless steel when subjected to adhesive wear loading. The weight loss (WL) and the specific wear rate (SWR) of the mild steel using each of the prepared lubricants were determined. Scanning electron microscopy was used to examine the worn surface of the mild steel. The results revealed that pure canola oil as a lubricant performed competitively against a blend of 80% synthetic and 20% canola oils. The viscosity of the canola oil and its various blends with synthetic oil are controlled by the environmental temperature since an increased temperature reduces the viscosity. Also, the experimental results revealed that operating parameters play the main role in controlling the wear behavior of mild steel since increasing the sliding distances increases the weight loss. The specific wear rate exhibited a steady state after about 5 km sliding distance, and different blends influenced the applied loads and velocity differently. The mixing ratio of canola and syntactic oil was not particularly significant since the pure canola oil exhibited competitive wear performance compared with the blends. However, an intermediate mixing ratio (40%–60% synthetic oil mixed with 60%–40% canola) can produce a slightly low specific wear rate among other things.

“…The review discussed in this sub-section [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 ] concludes that experimental work completed so far for slurry and cavitation erosion is encouraging but lacks similarity with the field studies. There is a need for the appropriate design, development and execution of experiments to reasonably predict the wear in both cases.…”

“…The techniques discussed in this section are in their preliminary phase and will take time to become mature. Tang et al [ 23 ] studied the interesting behavior; that by increasing the fluid viscosity, the erosion rate decreases significantly. Fluid viscosity enhances the tearing effect and limits the solid erodent’s motion and minimizes the impact energy, which results in the erosion loss reduction.…”

Centrifugal pumps are being widely used in various industries for moving fluids that carry solids through pipelines where the need of head and flow rate is not high. Slurry erosion and cavitation are an extremely complex and not yet fully understood phenomenon that occur in centrifugal pumps; however, these undesirable phenomena can be reduced to a certain extent. Appropriate design and development of experiments is required to reasonably predict slurry erosion and cavitation. However, CFD methodology complements analytical solutions and experiments whenever testing of equipment has limitations. The current paper highlights the various slurry erosion and cavitation reduction techniques utilized by different researchers. Economic analysis conducted for a case study relevant to centrifugal pump (CP) usage in Pakistan shows that an 8% enhancement in pump efficiency can reduce the life cycle cost to about 17.6%, which could save up to USD 4281 for a single pump annually in Pakistan.
