Nylon nucleic acids containing oligouridine nucleotides with pendent polyamide linkers and flanked by unmodified heteronucleotide sequences were prepared by DNA templated synthesis. Templation was more efficient than the single-stranded synthesis: Coupling step yields were as high as 99.2%, with up to 7 amide linkages formed in the synthesis of a molecule containing 8 modified nucleotides. Cont...

We assess the performance of wire leaders, which some jurisdictions have banned to reduce shark mortality from pelagic longline fishing. Experiments were conducted on commercial vessels that deployed equal numbers of wire and nylon monofilament leaders randomly along their longlines. Catch rates of several species, including sharks, were significantly lower on nylon than on wire leaders, probab...

Functional nylon 6,6 nanofibers incorporating cyclodextrins (CD) were developed via electrospinning. Enhanced thermal stability of the nylon 6,6/CD nanofibers was observed due to interaction between CD and nylon 6,6. X-ray photoelectron spectroscopy and attenuated total reflectance Fourier transform infrared spectroscopy studies indicated the existence of some CD molecules on the surface of the...

This comparative study analyzes the relationship between archaeological interventions in districts of Supe Puerto and Paramonga, located province Barranca, department Lima, anda identity formation their respective secondary school student groups. To understand this relationship, semi-structured interviews were conducted with students, information on general was reviewed, most representative sit...

Purpose: To compare the outcome of corporeal plication using absorbable versus nonabsorbable sutures for the treatment of congenital penile curvature. Materials and Methods: Thirty-eight men older than 15 years old with congenital penile curvature were enrolled in the study. Patients were randomly divided into two equal groups based on the suture material (Nylon versus Vicryl) used in corporeal...

Industrial oil spills into aquatic environments can have catastrophic environmental effects. First responders to oil spills along the coast of the Gulf of Mexico in the southern United States have used spunbond nylon fabric bags and fences to separate spilled oil and oil waste from contaminated water. Low area mass density spunbond nylon is capable of sorbing more than 16 times its mass in low ...

The revolution of 3D-printing technology has caused an additional source plastic waste, especially the new generation composite filaments that are linked with commercial fused deposition modeling process, adding pressure to find a sustainable solution tackle emerging waste problem. This study aims investigate mechanical and thermal properties blended recycled material produced by mixing two dif...

Dissimilar material bonding is a challenge constantly being considered within engineering. This paper presents method for tailoring metal surfaces by covalently grafting polymers that are directly complimentary to their respective dissimilar material. Acrylic acid was grafted onto the surface of aluminium which subsequently bonded poly-lactic (PLA), nylon-6, and nylon-6/carbon fiber hybrid via ...
