Harvesting of solar energy by photovoltaic cells has the potential to compensate for this large energy requirement. As commercially available silicon-based solar cells have many disadvantages like high processing cost, rigidity, etc., organic solar cells are currently the subject of extensive research as an alternative to replace them. Because of the development of highly efficient donor-acceptor material, this type of solar cell has achieved a remarkable power conversion efficiency (PCE) above 20 %. Along with that side chain engineering of the active large and efficient optimization of nanoscale morphology of the active material also helps to enhance the performance of the solar cells. Generally, photovoltaic cells are composed of a cathode, anode, active layer made with donor and acceptor materials, and transparent substrate material. The active layer plays a pivotal role in the performance of the device and it mainly determines how effectively organic solar cells can convert solar energy to electrical energy. Furthermore, the substrate is also a crucial component since all other layers are deposited on it, allowing sunlight to pass through while serving as a barrier to shield the solar cells. In this review article, we have specifically concentrated on the development of active layers, substrate material, and the effects of nano-scale morphology.

Bio-based materials, including those derived from agricultural waste, exemplify the innovative recycling strategies central to circular economies, offering environmentally friendly alternatives to traditional petrochemical-based products. In this context, terahertz (THz) technology, widely employed in non-destructive testing, detection, imaging, and quality control in various industries, holds considerable potential for enhancing the production and quality of biopolymers. Although THz characterization techniques do not directly improve biopolymer performance, they can optimize production processes by providing detailed insights into material properties, thus contributing to the enhancement of biopolymer quality and, in turn, indirectly extending their lifecycle.

Amongst various Mg alloys, AZ91 alloy has been trending and needs to be completely explored. The corrosion resistance of AZ91 alloy has always been a question, hence needs further investigation. The impact of face milling operations under cryogenic conditions on the corrosion properties of AZ91 alloy is studied in the current work. Using electrochemical polarization testing technique with a 3.5 % NaCl solution, the optimal surface finish of the alloy produced by cryogenic assisted face milling has been contrasted with dry milling. The polarization method compares both specimens after testing them for 0.5 h. Cryogenic machining considerably minimized the roughness by upto 28 % with values ranging between 0.0525 µm and 0.1169 µm when compared to the 0.1259 µm and 0.0691 µm from dry condition. The comparatively low roughness surface from cryogenic condition demonstrated a relatively low corrosion rate (1.1992 mm/year in cryogenic; 1.2891 mm/year in dry), indicating that the corrosion rates are directly related to the surface roughness. The superior corrosion resistance of the cryogenic milled surface over the dry milled surface was supported by the polarization curves. Additionally, the elemental analysis test on the surfaces after the polarization test revealed that the cryogenic milled surface had less oxygen (44.28 wt% and 7.29 wt%) than the dry milled surface (47.13 wt% and 10.01 wt%), proving the superior corrosion resistance of cryogenic milled surface.</div></div>","PeriodicalId":100958,"journal":{"name":"Next Materials","volume":"8 ","pages":"Article 100600"},"PeriodicalIF":0.0,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143684504","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}

However, conventional PUs typically depend on petroleum-derived polyols, which present notable environmental and health challenges. To mitigate these issues, bio-based polyols have been developed as sustainable substitutes. Among these, vegetable oil (VO) based polyols have garnered significant attention for their potential to diminish dependence on fossil fuels. Even though bio-based PUs are better for the environment, they nevertheless have problems with good mechanical strength. Improving the mechanical properties of bio-based PUs is the goal of this research. To do this, several diols with aliphatic and aromatic nature are used as cross-linkers, including 1,3 propanediol (PR),1,5-pentanediol (PN), and hydroquinone (HQ). The effects of different aromatic and aliphatic diisocyanates on the thermosetting PU production process are being investigated. By adjusting the cross-linkers and diisocyanates, the mechanical strength and stiffness of the PU films are anticipated to increase. Samples containing methylene diphenyl diisocyanate (MDI) exhibited a tensile strength of approximately 40 MPa, up from 6 MPa in the control samples when crosslinked with HQ (10 wt%). For hexamethylene diisocyanate (HDI) based PU films, the sample with the maximum tensile strength of 9 MPa was PR-15 wt% (H). Also, elongation was better in films containing HDI than in films having MDI. Further evaluation of the cross-linking and stiffness of these PU films was performed using thermal experiments, examination of gel content, and degree of swelling.</div></div>","PeriodicalId":100958,"journal":{"name":"Next Materials","volume":"8 ","pages":"Article 100609"},"PeriodicalIF":0.0,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143684626","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}
