Abstract: A simple, efficient, and ecofriendly method was employed to synthesize TiO2/ZrO2/SiO2 ternary nanocomposites using Prunus × yedoensis leaf extract (PYLE) that shows improved photocatalytic and antibacterial properties. The characterization of the obtained nanocomposites was done by X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, field-emission scanning electron microscopy (FE-SEM), and energy-dispersive X-ray spectroscopic (EDS) analysis. The synthesized ternary nanocomposites with nanoscale pore diameters were investigated for the elimination of Reactive Red 120 (RR120) dye. The obtained results showed about 96.2% removal of RR120 dye from aqueous solution under sunlight irradiation. Furthermore, it shows promising antibacterial activity against Staphylococcus aureus and Escherichia coli. The improved photocatalytic and antibacterial activity of TiO2/ZrO2/SiO2 may bring unique insights into the production of ternary nanocomposites and their applications in the environment and biomedical field.

Abstract: Clean technology-based natural fiber composite fabrication is the prime aim of this piece of research. Natural fibers highly replace metal usage in industries and automobile, marine, medical applications, and so on. Vast amounts of natural fibers are freely available in all areas. In this research, work nanofiller material such as nano form waste coir fiber is collected from used car seat. The 10 wt.% of nanofiller material is added to the preparation of natural nanocomposites (ramie and abaca fiber). Hybrid composites are fabricated with the influence of different process parameters, namely, fiber weight percentage (20 wt.%, 30 wt.%, 40 wt.%, and 50 wt.%), NaOH action % (4%, 6%, 8%, and 10%), compression pressure (9 MPa, 12 MPa, 15 MPa, and 18 MPa), and temperature (100°C, 120°C, 140°C, and 160°C). Furthermore, the strength of this hybrid composite has analyzed by conducting flexural, impact, and shore hardness tests. These tests have provided the influence of selected parameters and their effects on the results of experimental work. In the flexural analysis, 6% of NaOH action has offered maximum flexural strength of the specimens. Correspondingly in the impact test, 30 wt.% of fiber is produced higher impact strength. Finally, applying 15 Mpa of compression pressure records the maximum shore hardness.

Abstract: Aluminium alloy strengthened with the ceramic particle is widely utilized for numerous engineering usages owing to its less weight, and superior mechanical and tribological behavior. The purpose of this research is to manufacture AA6063-Nano AlN composites via stir casting (SC) process and to examine the mechanical, tribological, electrical, and thermal and CNC drilling behavior. Nano AlN was mixed with AA6063 at 4, 8, and 12 wt.%. The occurrence and dispersal of Nano AlN particles in AA6063 matrix were inspected via Scanning Electron Microscope (SEM). The density and porosity were explored. The mechanical studies on microhardness, tensile strength and yield strength, flexural strength, and compressive strength have been done. SEM fractographic examination was made on the tensile fracture s les. The thermal conductivity, electrical resistivity and electrical conductivity, and salt spray corrosion analysis were made on the produced composites. The tribological behavior of the composites was studied using numerous parameters, reinforcement wt.%, load (L), sliding velocity (SV), and sliding distance (SD). The worn surface examination was done via SEM. The CNC drilling behavior was done at different parameter speed (S), feed (F), and depth of cut (DOC). Experiments were carried out according to the L9 orthogonal array (OA). Optimal process parameter to attain higher material removal rate (MRR) and least surface roughness (SR) was identified via Grey Relational Analysis (GRA). ANOVA outcomes revealed that feed rate is the foremost noteworthy parameter (45.89%) influencing MRR and SR.

Abstract: There is a constant drive to improve disease treatments. Much effort has been directed at identifying less immunogenic anti-cancer agents that produce fewer and less severe side effects. For more than a decade, bacteriophages have been discussed as an effective treatment for cancer with an exact mode of delivery. We review how bacteriophages are used in cancer treatment, the underlying therapeutic mechanisms, and the tumor attacking peptide screening process. The filamentous bacteriophages are an effective vehicle for delivering displayed peptides toward the tumor target. The peptide must be expressed at the appropriate coat protein, and the peptide must be effective enough to disrupt the complex cancer matrix. The present review also sheds light on the dynamic use of phage in cancer treatment, from detection and diagnostics to treatment. Phage has a versatile role as a diagnostic and therapeutic tool. By acting as an appropriate recombinant drug, this phage has every potential to replace existing laborious, high capital investing therapies that may at many times result in failure or drastic side effects. One of the most significant challenges would be identifying tumor homing peptides. Although a few have been discovered, the most effective ones are yet to be determined. This therapeutic method plays a significant role in tumor therapy with high accuracy and efficiency, irrespective of the target location.
