This unique and significant group of compounds has a special relationship with inorganic clay minerals, which are hydrous aluminium phyllosilicates. Clay minerals, known to be typical layered materials, act as unique hosts for porphyrin molecules or their precursor materials. When the porphyrin compound enters between the layers of a clay, it can orient horizontally, diagonally, or perpendicularly. Cation-exchanged clay can provide the acidity required for the formation of porphyrins from its precursor molecules without the need for other auxiliary factors such as heating. Clays are also capable of facilitating the incorporation of various metals into the porphyrin ring to form a metalloporphyrin. The properties of these metalloporphyrin clay complexes have been studied extensively. Modern applications of such clay-porphyrin materials include their use as heterogeneous catalysts for oxidation and polymerization reactions in the synthesis of new materials. These heterogeneous catalysts have a wide range of uses in vital sectors, such as food manufacturing, pharmaceuticals, and the chemical industry. Additionally, clay-porphyrin systems are employed in constructing various types of self-assembling artificial photo-synthesis systems.","PeriodicalId":9765,"journal":{"name":"Chemical and Biochemical Engineering Quarterly","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141647615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These encompass selecting appropriate excipients, comprehending miscibility and solubility factors, ensuring efficient drug encapsulation and release, assessing stability, and facilitating drug transport in the bloodstream for accurate targeting and attachment. To address these intricate issues, a range of molecular computational models is utilized. These models include quantum mechanical simulations that handle the smallest particles and move through atomistic molecular dynamics for detailed molecular interactions, coarse-grained molecular dynamics (MD) for larger scale phenomena, and dissipative particle dynamics (DPD) for mesoscale modeling. Further scaling up, computational fluid dynamics (CFD) is used for fluidic behaviors, discrete element modeling for large particle systems, and both pharmacokinetic/pharmaco-dynamic (PK/PD) and physiologically based pharmacokinetic (PBPK) modeling for whole-body dynamics. These methodologies play a crucial role in elucidating the complex mechanisms involved in the development of nanoparticle formulations and are essential in the creation of varied organic and inorganic systems for drug delivery. This review primarily concentrates on these computational simulation models and their significance in the context of nanoparticle-based drug delivery systems.","PeriodicalId":9765,"journal":{"name":"Chemical and Biochemical Engineering Quarterly","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141647176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Naringin, the dominant flavonoid responsible for bitterness in citrus fruit juice, can be mitigated by the enzyme naringinase. This study focuses on the isolation of novel naringinase-producing bacterium from mandarin orange peel, followed by the production and partial purification of naringinase. The bacterial strain exhibiting the highest enzyme production potential was identified as Bacillus megaterium AULS 1. The effects of carbon source (naringin) concentration, inducer (naringenin), pH, and temperature on narin-ginase production were investigated. Optimized conditions yielded a maximum naringi-nase production of 386.43 U mL –1 . The produced enzyme was partially purified using ammonium sulfate precipitation and dialysis. The effects of pH, temperature, and metal ion concentration on the activity of the partially purified enzyme were evaluated, resulting in a highest activity of naringinase of 539.25 U mL –1 under optimized conditions. The debittering activity of the partially purified enzyme was 45.78 %. These findings demonstrate that Bacillus megaterium AULS 1 has the potential for naringinase production, and can be utilized for debittering citrus juices.","PeriodicalId":9765,"journal":{"name":"Chemical and Biochemical Engineering Quarterly","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141645282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to the improvement in flow characteristics, this study presents the basic dimensionless characteristics in regression form, along with the measurement of the Metzner–Otto constant. These characteristics are essential for the use of the paddle mixer as an onsite rheometer, enabling rapid and straightforward evaluation of the desired rheological properties of the prepared mixture. The performance of the paddle mixer was assessed through homogenization experiments and power input measurements at various rotation speeds. The paddle mixer displayed creeping flow behavior up to a Re value of 50. The geometry of the paddle mixer was modified to achieve homogeneity throughout the volume, significantly influencing mixing mainly in the axial region of the mixer. To compensate for the non-Newtonian behavior, the Metzner–Otto approach was employed. Under creeping flow conditions and for pastes displaying flow index above 0.5, the paddle mixer can be characterized by a Metzner-Otto constant of 54.","PeriodicalId":9765,"journal":{"name":"Chemical and Biochemical Engineering Quarterly","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141646351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These devices are widely used in both clinical/hospital settings and at-home care. A prototypical example is the treatment of nephrological diseases through hemodialysis and continuous renal replacement therapy using a hemodialyzer or an artificial kidney. The various applications of ETDs share common limitations such as coagulation, hemolysis, air embolism, and sensitivity reactions, all of which arise from the interactions of human physiology with the treatment mechanisms. Researchers are implementing microscale-based technology to achieve the next-generation ETD that can address persistent problems and improve therapeutic performance. This review article focuses on the evolution of the structure and development of conventional ETDs towards the miniaturization of the device. We begin with a narrow but common definition of ETDs as well as their current form and uses for renal replacement followed by a review of the importance and progression of microscale-based ETD development together with future directions towards achieving fully functional micro-scale-based ETDs that reflects contemporary technological and engineering advancements.","PeriodicalId":9765,"journal":{"name":"Chemical and Biochemical Engineering Quarterly","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139526045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
