We focus on the reduction in friction losses by the dilute addition of high-molecular weight polymers and/or fibers to flowing liquids. Although it has long been reasoned that the dynamical interactions between polymers/fibers and turbulence are responsible for DR, it was not until recently that progress was made in elucidating these interactions in detail. Advancements come largely from numerical simulations of viscoelastic turbulence and detailed measurements in turbulent flows of polymer/fiber solutions. Their impact on current understanding of the mechanics and prediction of DR is discussed, and perspectives for further advancement of knowledge are provided.","PeriodicalId":17828,"journal":{"name":"KONA Powder and Particle Journal","volume":"65 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2021-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87119108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ambrose","doi":"10.14356/kona.2021007","DOIUrl":"https://doi.org/10.14356/kona.2021007","url":null,"abstract":"Consistency and reliable flow are of great concern during the handling and processing of flour. In this study, wheat flour was consolidated by normal stress and vibration, and rheological factors including bulk solid compressibility, Warren-Spring cohesion strength, permeability, and wall friction were evaluated. Soft red winter (SRW) and hard red spring (HRS) wheat flours were vibrated for 5 and 10 minutes and compressed under 10 and 20 kPa for 12 and 24 h. After vibration, wall friction increased from 10.87° to 14.13° for SRW flour and decreased from 11.00° to 7.10° for HRS flour, and the permeability decreased for both the flours. Consolidation time and stress had a significant effect ( P < 0.05) on wall friction and compressibility. The HRS Carr index increased from 25.77 to 38.48 when consolidated under 20 kPa for 24 hours, but the SRW Carr index decreased slightly from 46.60 to 44.24. The SRW flour permeability decreased significantly ( P < 0.05) when compression pressure was increased from 10 to 20 kPa. while HRS permeability was less affected by consolidation. The consolidation and vibration effects on bulk flour properties differed likely due to inherent differences in the composition and hardness of HRS and SRW.","PeriodicalId":17828,"journal":{"name":"KONA Powder and Particle Journal","volume":"38 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2021-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80664509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The instrument modulates compression and decompression steps, allowing scrutiny of the overall compression response of samples. Compared to established methods for the determination of density and related parameters for pharmaceutical powders, this instrument has the capability of measuring smaller samples. The relative humidity can also be controlled in the instrument (3 % to 95 % RH), allowing assessment of the effect of moisture on compression response. We have used the instrument to determine the compressed bulk density of Trehalose, Leucine, Trileucine, and Mannitol powders of varying crystalline and amorphous compositions and particle size and size distribution, demonstrating that the new modulated compression tester is suitable for low pressure (< 1200 kPa) density measurement of respirable powders (< 10 μm) and expensive active pharmaceutical ingredients available in limited quantities (typical sample mass requirement of < 100 mg). In addition, the modulation feature of the instrument allows the analysis of the transition from plastic to semi-elastic compression response. The outputs and features of this instrument are useful for formulation development, quality control measurements, discerning between different or similar powders due to differences in the compression response, and optimizing powder compression parameters for pharmaceutical applications.","PeriodicalId":17828,"journal":{"name":"KONA Powder and Particle Journal","volume":"188 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2021-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73925847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The KONA Award 2019","authors":"","doi":"10.14356/kona.2021023","DOIUrl":"https://doi.org/10.14356/kona.2021023","url":null,"abstract":"The KONA Award 2019 was presented to Dr. Makio Naito, Professor of Joining and Welding Research Institute, Osaka University, Japan. He has conducted ground breaking and foundational studies contributing to novel powder processing technology to develop advanced materials to address energy and environmental issues. He aimed to develop smart powder processing techniques to support green and sustainable manufacturing of advanced materials. He has pro-posed and advanced new concept to achieve direct bonding between particles by activating their surfaces with mechani-cal energy, without any externally applied heat or added binders of any kind in the dry phase. By introducing controlled composite particles made by the direct bonding as precursors, new microstructure electrodes for Molten Carbonate Fuel Cells (MCFC) and Solid Oxide Fuel Cells (SOFC) have been created. Based on this concept, Professor Naito has pro-duced electrodes for SOFC that operate at lower temperature, and developed other new materials such as fibrous nanoparticle compacts having high thermal insulation performance at the high temperatures. By making use of particle bonding, he has developed a new one-pot processing method to synthesize nanoparticles without applying extra heat. Furthermore, the one-pot processing method can combine the synthesis of nanoparticles and their bonding with other particles to make nanocomposite granules in one step. Nanostructured granules of active materials for the cathodes and anodes for lithium ion batteries have been successfully synthesized by this novel method. Now, Professor Naito is developing electrodes for all-solid-state lithium ion batteries in collaboration with industry partners to reduce the huge thermal energy consumption traditionally required to manufacture high quality powders and ceramics. Professor Naito has also conducted research on powder processing to increase the performance and reliability of advanced ceramics, which is a very important issue in engineering ceramics. He has developed characterization tools to examine the evolution of large defects in ceramics during processing. Applying these tools in the ceramics manufacturing process, he has elucidated the failure mechanism, and demonstrated that very few large particles and/or large pores will","PeriodicalId":17828,"journal":{"name":"KONA Powder and Particle Journal","volume":"22 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2021-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78722298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
