Despite the growing trend towards recycling, there are currently no effective technologies to offset the continuous increase in plastic production. Polyesters and polyamides are among the most widely produced single-use plastics, mainly used in the manufacture of textiles and soft drink bottles. Currently, only a small proportion of these polymers can be effectively recycled. The two primary methods employed for this purpose are mechanical and chemical recycling. Presently, mechanical recycling remains the more widely adopted process within the industrial sector. However, the treatment process is limited to a narrow range of waste materials as it is impossible to remove dyes and the mechanical properties deteriorate due to incompatibility between different plastic materials. Another critical limit of this recycling technology is the limited number of recycling loops that can be done due to the thermal degradation that occurs during the extrusion process. The alternative option is chemical recycling, which allows the depolymerization of the original product to recover the monomers directly. The main drawbacks are the long reaction times and the many solvents needed to achieve high-purity products. As a results, chemical recycling is only economically feasible for large companies that can produce the virgin polymer <em>in situ</em>. In this work, a new technology has been patented. This process consists of three main steps. The first one is the distillation-assisted cyclodepolymerization (DA-CDP), introduced as a modification of the CDP process. In this unit, cyclic oligomers together with high molecular weight compounds are produced. Then, after polymer purification, it is possible to achieve the same molecular weight as the initial polymer in less than 30 min, exploiting the ring-opening polymerization (ROP) of the next step.</p></div>","PeriodicalId":100728,"journal":{"name":"Invention Disclosure","volume":"4 ","pages":"Article 100026"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772444124000077/pdfft?md5=6f1761dd4e4424d4ed83c84cf75d7880&pid=1-s2.0-S2772444124000077-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141541120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, biodiesel appears as a potential liquid fuel for replacing petroleum diesel. Here we have utilized waste snail shells as a cost-effective material which will reduce the overall biodiesel manufacturing cost. We obtained a remarkable biodiesel yield of 96.1 % with a very low activation energy (30.45 kJ mol⁻¹). The catalyst displayed exceptional stability, maintaining consistent catalytic activity over six consecutive cycles without experiencing a notable decline.

This invention disclosure introduces a novel tri-axial hip replacement design aimed at addressing these issues. The design incorporates three orthogonal cylindrical articulations, each providing one rotational degree of freedom to replicate the natural movements of the hip joint. The prosthesis comprises two components made from UHMWPE (cup and rotator) and two components made from high-N stainless steel (flexor and abductor). Each articulation consists of metal-on-polyethylene bearing couples. Unlike traditional ball-and-socket implants, the novel design limits motion within each articulation to a single direction, taking advantage of friction-induced UHMWPE strain hardening. Moreover, cylindrical joints offer a larger contact surface area than their spherical counterparts, thereby reducing contact stresses. Mid-sized high-fidelity prototypes underwent wear resistance testing, demonstrating significantly superior performance compared to a commercial ball-and-socket implant of similar size tested in the same conditions. Moreover, a cadaveric implantation performed by experienced orthopaedic surgeons showed the implant has good stability even for postures requiring a wide range of motion. This innovative design represents a promising advancement in hip replacement technology, offering improved wear resistance and longevity, thus potentially reducing the need for revision surgeries and enhancing patient outcomes.</div></div>","PeriodicalId":100728,"journal":{"name":"Invention Disclosure","volume":"4 ","pages":"Article 100030"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142422220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main welding process used to join the products is MIG welding, which has several flaws, including low weld-metal toughness, spatter formation, undercut formation, and finally poor tensile strength and toughness. The company also uses TIG welding, which uses an inert gas to produce less smoke and fumes. While this technology produces precise welds, it is a time-consuming operation with a lower production rate. As a result, a special type of welding process is required that incorporates the properties of both types of welding processes. As a result, the hybrid TIG-MIG welding configuration was proposed. The optimization of process parameters of EN24 mild steel material for TIGMIG hybrid welding is presented in this paper. The test was carried out on a 6 mm EN24 mild steel plate. The butt joint configuration was used. MIG welding current, TIG welding current, MIG welding voltage, TIG welding voltage, and welding gun travel speed were used as process parameters. A single-level L27 orthogonal array is used to optimize process parameters. Tensile and hardness tests are used to evaluate the mechanical properties of the weld joint. The optimum level setting of the test, according to the mean effect plot of GRG, is MIG welding current of 200 A, MIG welding voltage of 15 V, TIG welding current of 200 A, TIG welding voltage of 18 V, and welding gun travel speed of 5 mm/s. The significant process parameters were investigated using ANOVA. MIG welding current and MIG welding voltage were significant factors in the ANOVA, with percentage contributions of 44.19 % and 49.20 %, respectively. Five confirmation tests were performed, and the results show that the mean grey relational grade of the conformation test was 0.7594, which falls within the 90 % confidence interval, indicating that the experiment is reliable. Finally, MIG welding, TIG welding, and TIG-MIG hybrid welding processes were compared, with the results indicating that TIG-MIG hybrid welding has the highest hardness and tensile strength of all. Based on the findings, it is possible to conclude that the company should use the hybrid welding method to improve the weld joint's hardness and tensile strength.</p></div>","PeriodicalId":100728,"journal":{"name":"Invention Disclosure","volume":"4 ","pages":"Article 100016"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772444123000071/pdfft?md5=3aeb31e9879780b0c9330ac4a844665c&pid=1-s2.0-S2772444123000071-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136094976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"A steel joint for driven precast concrete geothermal energy pile foundations","authors":"Habibollah Sadeghi,&nbsp;Rao Martand Singh","doi":"10.1016/j.inv.2024.100028","DOIUrl":"10.1016/j.inv.2024.100028","url":null,"abstract":"<div><p>This invention describes a steel joint used for connecting two precast concrete driven energy pile (DEP) segments which is known as DEP joint. Precast concrete DEPs are cast in segments with a maximum length of 12 m at a concrete factory. DEPs are typically driven into the ground until bedrock; hence, in places where the bedrock is deeper than 12 m, two or more segments must be connected using a joint to produce longer energy piles. DEPs have not been frequently used because no suitable joint existed that could maintain structural integrity and provide leak-proof coupling between the pipes at the joint interface. The present invention addresses this problem by designing a steel joint that can meet the structural and hydraulic requirements of a suitable steel joint for DEPs. Each quadratic concrete energy pile segment is prefabricated in a concrete factory, where the heat transfer pipes are embedded inside the steel cage of each segment. The steel DEP joint is installed at one or both ends of each concrete segment, and has two or four sidewall channels, depending upon its size. Heat transfer pipes are coupled between every two segments, inside the sidewall channels, while the energy piles are installed at a construction site. The sidewall channels are protected using steel shielding plates that are riveted to the joint so that the pipes and the coupling inside the sidewall channels are protected against harsh frictions during the installation of the DEPs in the ground. The steel joint facilitates the installation of longer precast concrete energy piles up to the bedrock depth, especially in sites where the bedrock is deeper than a single segment length. The main advantages of precast concrete energy piles compared to cast-in-place piles are that they enable better quality control and quality assurance, as well as being easier, faster, and cheaper to install. The invented DEP joint has passed structural integrity tests as required according to the BS EN 12794 standard, and also passed hydraulic pressure tests according to the ASTM F2164 – 21; hence, it is certified to be used in construction projects. We are now looking for potential licensees to start manufacturing the joints and using them in the energy pile industry.</p></div>","PeriodicalId":100728,"journal":{"name":"Invention Disclosure","volume":"4 ","pages":"Article 100028"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772444124000090/pdfft?md5=42485897c1eee43fb65646ba81ee5fb2&pid=1-s2.0-S2772444124000090-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141852853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
