Liquid photopolymers are used in applications such as 3D printing, where they are deposited layer by layer and cured by exposure to light. Solid photopolymers, also known as photoresists, are used in applications such as lithography and microfabrication, where they are applied as a thin film and selectively exposed to light to create a pattern. The properties of photopolymer materials, such as mechanical strength, thermal stability, and chemical resistance, can be tailored by adjusting the monomer type, photo initiator type, and processing parameters such as the exposure time and intensity. Overall, photopolymer materials are a versatile and widely used type of polymer material that can be tailored for specific applications through the choice of monomer, photo initiator, and processing parameters. Photopolymer-metal composites based on metal foil deposition on additive manufactured substrates are a technique for creating composite materials with a combination of metal and polymer properties. This approach involves the deposition of a thin layer of metal foil onto a 3D printed polymer substrate, which is then cured using photopolymerization to create a composite material with unique properties.","PeriodicalId":232294,"journal":{"name":"Journal of Metallic Material Research","volume":"1 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138949344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study uses a complex dynamic turning model with two degrees of freedom for the orthogonal cutting system. Tool holders made from different materials, including Al 5083, Al 6082, Al 7012, and a standard 4140 material, were subjected to chatter vibration to investigate their process damping capabilities. The study found that the standard tool holder 4140 allows for higher stable depths of cut and produces similar process damping values compared to the other tool holders. Finite element analyses (FEA) were performed to verify the experimental results, and the modal and FEA analyses produced very similar results. The study concludes that future research should investigate the effects of tool holders made from high alloy steel alloys on process damping. Overall, this paper provides important insights into the effects of tool holder materials on chatter vibration and process damping in turning operations, which can help in the design of more efficient and effective cutting systems.","PeriodicalId":232294,"journal":{"name":"Journal of Metallic Material Research","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134292365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Readily availabledrugs are getting ineffective by each passing day as the mutation is veryfast in these pathogenic microbes resulting in drug resistance. The growingresistance of bacteria necessitates the development of new and effectivecompounds of desired characteristics that could bar the rapid development ofbacterial cell inside of the host body. Along with cellular resistance for clinicalantibiotics, co-bacterial infections during microbial attacks (viz. virus, fungus,protozoans etc.) also demand for some novel antibacterial drugs having highefficacy and minimal side effects on human body. These antibiotics shouldalso be compatible with remedies ongoing for core microbial infections. So,in demand of search for effective antibacterial moieties, the scope of transitionmetal complexes as drug gives a good signal against the pathogenic bacteriaby inhibiting their growth. The action of metal complexes on bacterial cellmay be due to impremiablity, enzymatic interruptions, ribosomal interactions,disturbance in the path of protein synthesis, denaturing of genetic materialsetc. inside the cell. Metals in complexes may interrupt the lipophilisity throughthe bacterial cell wall. Inclusion of metal ions in organic moieties behavingas ligand delocalize π-electrons upon the entire chelate ring and this chelationresults in overlapping of ligand orbital and partial sharing of (+)ve chargeof metal ion with donor atoms.

The temporal andspatial variation of arsenic was evaluated by examining its concentrationsbetween March 2015 and December 2021. Values between March 2015and December 2019 were evaluated as pre-pandemic, and values betweenMarch 2020 and December 2021 were evaluated as post-pandemic. Theresults were compared with national and international standards and thechronic and cancer risks were calculated for adults. When the 7-yeargeneral averages were examined, it was seen that the highest concentrationwas 0.0256 mg/L at the 8th Station, and the lowest concentration was0.0182 mg/L at the 1st Station. The reason why the highest value is atthe 8th station was that the wastewater of Nilüfer and Bursa OrganizedIndustrial Zones was discharged to Bursa West Wastewater TreatmentPlant before this station. After the pandemic the raises in concentrationswere observed at all stations, except for the 3rd Station. This shows thatthe pollution load had increased in general during the pandemic. However,it was estimated that there was a decrease in the pollution load of theindustrial wastewater coming to the 3rd Station, which was located afterthe Eastern Wastewater Treatment Plant of the City. It was observed thatall stations examined were higher than drinking water standards and lowerthan irrigation water standards according to WHO and Turkish NationalStandards. All measuring stations were greater than 1 of the hazardquotient (HQ) values. In terms of human consumption risk, all stations hada chronic and carcinogenic risk according to the values before and afterthe pandemic.
