The goal of this project was to research and propose the implementation of a polyethylene terephthalate (PET) recycling plant. The recommended process is recycling PET flakes into its base polymers and monomers via a hydrolase enzyme biocatalyst. The current design with supporting utilities and operations has an estimated total capital investment of $54.68 million dollars. The team recommends selling terephthalic acid (rTPA) at $2.21 per kilogram to reach a net present value of $0 after 10 years. This price is not yet competitive with the current market of virgin TPA, which historically has been between $1.00 and $1.50 per kilogram. This process also produces liquid ethylene glycol (EG) and sodium sulfate salt (SS) that can be sold as co-products. The return on investment (ROI) is 24.4% and the venture profit is $1.34 million. Future work includes further optimization of rTPA pricing, on-site wastewater treatment, unit operation modification, and further lab development and research regarding the biocatalyst enzyme
This dataset details the force-displacement response of porcine meniscus in no-slip uniaxial compression. Samples are cut from the anterior, middle and posterior regions of the meniscus.
Prior work on black hole (BH) thermodynamics suggests the entropy depends not on the volume, but rather the surface area of the event horizon. Such findings highlight the intriguing nature of BHs and give rise to the idea that information may be entirely encoded on the surface. We study the case of a superficial Schwarzschild BH, and calculate the net force (Fnet) exerted on the surface of its spherical shell from the self-gravitational pull. We demonstrate that the Fnet is exactly c^4/4G, 3.025•10^43 Newtons, a force that is constant and independent of the size and the mass of the BH, meaning all such Schwarzschild BHs share the same Fnet. Surprisingly, the Fnet matches Fmax, the limit of the maximum force conjecture. This establishes a new potential connection between the formation of BHs and the Fmax. We demonstrate that under the validity of this Fmax, the mass of the superficial BH is contained at precisely the Schwarzschild radius. Finally, we provide further evidence to reject the concept of a point mass singularity and we theorize on the creation of a BH given the findings.
What if the universe has a limit on the amount of energy that a certain mass can have? This article explores this possibility and suggests a theory for the creation and nature of black holes based on an energetic limit.
This is the first comment/addition to the theory published with the title "A First Note to the Short Theory on the Creation and Nature of Black Holes".
