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}

The bottom-up process has been extensively used to produce functional materials for controlling the particle properties of composite particles. We propose crystallization at liquid-liquid interfaces as an advanced particle formation method. This review introduces crystallization at a liquid-liquid interface based on several case studies used in various applications. Conventional crystallization has been generally used to produce crystals and particles with homogeneous particle properties. Liquid-liquid interfacial crystallization makes it possible to create composite particles with hetero-phase structures and interfaces. Liquid-liquid interfacial crystallization with an inkjet technique can control the droplet size accurately, and the shape and particle size distribution are successfully controlled in inorganic-organic composite particles. In addition, we succeed in creating organic-organic composite particles using the interfacial crystallization by an ultrasonic spray nozzle. The coating efficiency of organic particles on the particles is enhanced using the ultrasonic spray nozzle in comparison with anti-solvent crystallization. In this study, the fabrication of inorganic-organic composite particles using a coaxial tube reactor on the liquid-liquid interfacial crystallization is proven successful. These findings suggest that liquid-liquid interfacial crystallization is a promising means of efficiently producing composite particles because of their applicability to infusion in various processes.","PeriodicalId":17828,"journal":{"name":"KONA Powder and Particle Journal","volume":"31 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2021-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90921988","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}

Traditional processing as CaO neutralization of acidic solutions is still a burden to many local governments of China and development of new process with lower cost is highly required. Mining exploitation produces large amounts of tailings in which industrial minerals such as carbonates, silicates and others have been left without proper utilization. Based on the intensive investigations in the field of mechanochemistry, we propose to use these mineral samples to deal with the purification of heavy metal polluted water by enhancing their reactivity through mechanochemical activation. The industrial minerals such as silicates (serpentine and kaolinite), carbonates (calcite) have been studied for the purposes on removal of contaminants from solution. In addition, the synergistic effects from mixtures of calcite with other material have been investigated to give their excellent adsorbent performance for purification of the wastewater.

Based on the multicycle calcination-carbonation reaction of CaCO 3 for both thermochemical energy storage and post-combustion CO 2 capture applications, the operating conditions for each application may involve remarkably different characteristics regarding kinetics, heat transfer and material multicycle activity performance. The novelty and urgency of developing these applications demand an important effort to overcome serious issues, most of them related to gas-solids reactions and material handling. This work reviews the latest results from international research projects including a critical assessment of the technology needed to scale up the process. A set of equipment and methods already proved as well as those requiring further demonstration are discussed. An emphasis is put on critical equipment such as gas-solids reactors for both calcination and carbonation, power block integration, gas and solids conveying systems and auxiliary equipment for both energy storage and CO 2 capture CaL applications.","PeriodicalId":17828,"journal":{"name":"KONA Powder and Particle Journal","volume":"16 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2021-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75145304","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 morphological analysis of the hybrid reveals the uniform coverage of the rGO sheets by IC-IO nanoparticles and the even distribution of carbon (C), oxygen (O), and iron (Fe) on the rGO nanosheets. As a result of the hybrid composition and controlled morphology, the surface area of the obtained IC-IO/rGO hybrid (~40 m2/g) is significantly enhanced compared to those of the calcined GO sheets and PB nanoparticles (without GO).","PeriodicalId":17828,"journal":{"name":"KONA Powder and Particle Journal","volume":"24 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2021-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75681958","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}

During the DEM parameter calibration process of a certain powder, several parameter combinations might lead to a similar bulk response, which could also vary for other bulk responses. Therefore, a methodology is needed in order to narrow down the number of combinations and be at once close to reality representation. In this study, a vertical auger dosing setup is used as a standard calibration device to extract three different bulk responses, i.e., angle of repose, bulk density, and mass flow rate. Simulations using LIGGGHTS software package are performed based on Design of Experiments (DoE) by varying four input factors, i.e., auger speed, particle-particle and particle-wall static friction coefficients, and particle-particle rolling friction coefficient. The successful application of multivariate regression analysis (MVRA) results in predicting the bulk behavior within the studied ranges of parameters. In this regard, clustering the different predicted behaviors of the three responses together allows to dramatically reduce the admissible parameter combinations. Consequently, an optimized set of calibrated DEM parameters is chosen, where the simulation results accurately match the experimental reference data. This simple dynamic calibration tool proves to strongly verify and predict the flowability of free-flowing bulk materials.","PeriodicalId":17828,"journal":{"name":"KONA Powder and Particle Journal","volume":"55 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2021-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78294728","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}
