The modulation of the morphology and structure of the quantum wires may give rise to the modulation of the energy levels and band offset positions to enhance the charge carriers transfer through any electronic device and improve the overall performance for the future application in the field of spintronics and photonics. Here, we proposed, for the first time, a novel rectangular architecture based Al_xGa_1-xAs and Ga_xIn_1-xAs quantum wires to engineer the electron energy spectrum according to a wide range of applications in electronics and optical devices. The electron energy levels in rectangular Al_xGa_1-xAs and Ga_xIn_1-xAs quantum wires with infinite potential barrier were calculated at different <i>x</i> values and different cross-section areas to explore the role of dopant and compared with the cylindrical shape. The calculations of the electron confinement energy in the first and second energy levels indicate that the energy value in cylindrical quantum wire is less than its value in rectangular one while for <i>E</i>₃ the energy value in cylindrical quantum wire is larger than its value in rectangular one for all values of <i>x</i>.

Similarly, lignin is a precursor for carbon fiber but requires plasticizers to be spun into fibers. This hampers their use in areas like carbon fiber production and tissue engineering, thus the reason for this study. Lignin was extracted from the plantain stem, and a lignin blend with PLA and PVA was made and electrospun into fibers. Thereafter, the physiochemical properties of the composite fibers were analyzed. The XRD spectra revealed increased crystallinity in PLA/Lignin fiber. When 0.75 wt.% of lignin was added to PVA, a new peak and peak shift were formed in the composite fiber, indicating strong interaction. The crystallinity of PVA/lignin decreased from 71.5 to 60.1% when 0.25 wt. % of lignin was added. DSC showed miscibility of polymers and improved melting temperatures from 155 to 228 °C, for PLA/lignin (0.5wt.%) fiber, but a reduction in melting temperatures of PVA, with higher lignin content (149–143 °C). FTIR showed notable functional groups, typical of PLA, PVA, and lignin, such as the OH group between 3800 and 3459 cm⁻¹. The minor peak shift in PLA/lignin showed that the level of molecular interaction is less than that of PVA/lignin. PLA/lignin displayed better fiber morphology compared to PVA/lignin, where fibers became sheet-like with higher lignin content. The addition of lignin improved the tensile strength of PVA (0.7 to 2.7 MPa). Conversely, PLA/lignin’s tensile strength decreased, due to reduced load transfer efficiency. Overall, PVA/lignin and PLA/lignin composites exhibit potential as reinforcement materials for biopolymers and carbon fiber precursors, with PVA showing more promise for carbon fiber production due to robust polymer-lignin interaction.</p></div>","PeriodicalId":592,"journal":{"name":"International Journal of Mechanical and Materials Engineering","volume":"20 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://jmsg.springeropen.com/counter/pdf/10.1186/s40712-025-00218-7","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143184750","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}

Here, we found that both magnetic properties and corrosion resistance of Nd-Fe-B magnets can be significantly improved by grain boundary diffusion (GBD) of Tb₆₉Ni₃₁ alloy. The diffusion temperature is a key factor in determining both the magnetic properties and corrosion resistance. The wettability of Tb₆₉Ni₃₁ alloy with the magnet and the fluidity of Tb₆₉Ni₃₁ alloy gradually increase with increasing temperature above 750 ℃, which facilitates the elements diffusion. Tb and Ni show different diffusion behaviors at different temperatures. The magnet diffused at a relatively high temperature exhibits high coercivity due to the formation of a thick Tb-rich shell in the grain with high magnetocrystalline anisotropy field. However, excessive grain growth leads to a reduction in coercivity as the diffusion temperature further increases. The highest corrosion resistance is achieved by Tb₆₉Ni₃₁ alloy diffusion at a relatively lower temperature. By analyzing the Volta potential distribution using scanning Kelvin probe force microscopy, the Ni-rich phase with high potential formed in grain boundaries is mainly responsible for the improved corrosion resistance.
