While human cognition excels in certain tasks, it is prone to biases that can distort our understanding. Applications of complex systems to engineering are often approximations of reality rather than exact truths. The concept of emergence is examined to illustrate how macroscopic behaviours in systems may not be easily reducible to their microscopic components, highlighting the importance of both reductionist and holistic approaches. The trade-offs between simple and complex models in solving real-world problems are discussed in the context of the limitations of models in capturing the full complexity of the real systems.</p>","PeriodicalId":9400,"journal":{"name":"Canadian Journal of Chemical Engineering","volume":"103 8","pages":"3512-3520"},"PeriodicalIF":1.6,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cjce.25764","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144551284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An electron beam illuminates the surface of a sample and produces backscattered electrons (BSE), secondary electrons (SE), characteristic X-rays, and light known as cathodoluminescence (CL). Combining energy dispersive spectrometry with wavelength-dispersive spectrometry improves trace analysis and differentiates overlapping X-ray lines, but the detection threshold is not much better than 100 ppm (parts per million). Implementing Monte Carlo simulation with better electronics and software are ongoing research areas to improve the method's precision, sensitivity, and spatial resolution. To detect Li, Be, and B (<span></span><math>\u0000 <mrow>\u0000 <mi>Z</mi>\u0000 <mo><</mo>\u0000 </mrow></math> 11) requires wavelength-dispersive X-ray spectroscopy (WDS), or soft X-ray emission spectroscopy (SXES), or a combination of BSE/EDS method.

Chemical engineering is ranked 21st among the 250 scientific categories that use the technique. It is also applied to reconstitute works of art and the antiquities.

Moreover, an overview of the various factors affecting enzymatic depolymerization of PLA have been done as well as the contribution of enzyme engineering in understanding the essential residues of these enzymes and improving their properties (e.g., thermostability and activity).
