Effects of rotor and stator geometry on dissolution process and power consumption in jet-flow high shear

Lin Yang, Wenpeng Li, Junheng Guo, Wei Li, Baoguo Wang, Minqing Zhang, Jinli Zhang

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 2,   Pages 384-398 doi: 10.1007/s11705-020-1928-7

Abstract: The jet-flow high shear mixer (JF-HSM) is a new type of intensified equipment with special configurations of the rotor and the stator. The mass transfer property and power consumption were studied in the solid-liquid system for a series of JF-HSMs involving different configuration parameters, such as rotor diameter, rotor blade inclination, rotor blade bending direction, stator diameter, and stator bottom opening diameter. The flow characteristics were examined by computational fluid dynamic simulations. Results indicate that the turbulent power consumption of the JF-HSM is affected by the change in rotor blade inclination and stator bottom opening. With the increase in the shear head size and the change in the rotor into a backward-curved blade, the solid-liquid mass transfer rate can be remarkably increased under the same input power. Dimensionless correlations for the mass transfer coefficient and power consumption were obtained to guide the scale-up design and selection of such a new type of equipment to intensify the overall mixing efficiency.

Layer-like FAU-type zeolites: A comparative view on different preparation routes

Bastian Reiprich, Tobias Weissenberger, Wilhelm Schwieger, Alexandra Inayat

Frontiers of Chemical Science and Engineering 2020, Volume 14, Issue 2,   Pages 127-142 doi: 10.1007/s11705-019-1883-3

Abstract: The creation of intergrown layer-like zeolite crystals is one route to form hierarchical zeolites. Faujasite-type (FAU-type) zeolites are among the industrially most important zeolites and the implementation of hierarchical porosity is a promising way to optimise their catalytic and adsorptive performance. After a short general survey into routes for the preparation of hierarchical pore systems in FAU, we will review the currently existing strategies for the synthesis of FAU with layer-like morphology. Those strategies are mainly based on the presence of morphology modifying agents in the synthesis mixture. However, a very recent approach is the synthesis of layer-like FAU-type zeolite crystals assembled in an intergrown manner in the absence of such additives, just by finely adjusting the crystallization temperature. This additive-free preparation route for layer-like FAU, which appears very attractive from an ecological as well as economic point of view, is highlighted in this review. Concluding, a comparison, including powder X-ray diffraction, scanning and transmission electron microscopy, nitrogen physisorption and elemental analysis, between conventional FAU and three layer-like FAU obtained by different synthesis routes was carried out to show the structural, morphological and textural differences and similarities of these materials.

Robotic distal pancreatectomy versus conventional laparoscopic distal pancreatectomy: a comparative study

Eric C. H. Lai,Chung Ngai Tang

Frontiers of Medicine 2015, Volume 9, Issue 3,   Pages 356-360 doi: 10.1007/s11684-015-0404-0

Abstract:

Robotic system has been increasingly used in pancreatectomy. However, the effectiveness of this method remains uncertain. This study compared the surgical outcomes between robot-assisted laparoscopic distal pancreatectomy and conventional laparoscopic distal pancreatectomy. During a 15-year period, 35 patients underwent minimally invasive approach of distal pancreatectomy in our center. Seventeen of these patients had robot-assisted laparoscopic approach, and the remaining 18 had conventional laparoscopic approach. Their operative parameters and perioperative outcomes were analyzed retrospectively in a prospective database. The mean operating time in the robotic group (221.4 min) was significantly longer than that in the laparoscopic group (173.6 min) (P = 0.026). Both robotic and conventional laparoscopic groups presented no significant difference in spleen-preservation rate (52.9% vs. 38.9%) (P = 0.505), operative blood loss (100.3 ml vs. 268.3 ml) (P = 0.29), overall morbidity rate (47.1% vs. 38.9%) (P = 0.73), and post-operative hospital stay (11.4 days vs. 14.2 days) (P = 0.46). Both groups also showed no perioperative mortality. Similar outcomes were observed in robotic distal pancreatectomy and conventional laparoscopic approach. However, robotic approach tended to have the advantages of less blood loss and shorter hospital stay. Further studies are necessary to determine the clinical position of robotic distal pancreatectomy.

Comparative transcriptomics revealed enhanced light responses, energy transport and storage in domestication

Zhiqiang XIA,Xin CHEN,Cheng LU,Meiling ZOU,Shujuan WANG,Yang ZHANG,Kun PAN,Xincheng ZHOU,Haiyan WANG,Wenquan WANG

Frontiers of Agricultural Science and Engineering 2016, Volume 3, Issue 4,   Pages 295-307 doi: 10.15302/J-FASE-2016126

Abstract: Cassava is a staple food, feed and bioenergy crop important to the world especially in the tropics. Domesticated cassava is characterized by powerful carbohydrate accumulation but its wild progenitor is not. Here, we investigated the transcriptional differences of eight cDNA libraries derived from developing leaf, stem and storage root of cassava cv. Arg7 and an ancestor line, W14, using next generation sequencing system. A total of 41302 assembled transcripts were obtained and from these, 25961 transcripts with FPKM≥3 in at least one library were named the expressed genes. A total of 2117, 1963 and 3584 transcripts were found to be differentially expressed in leaf, stem and storage root (150 d after planting), respectively, between Arg7 and W14 and ascribed to 103, 93 and 119 important pathways in leaf, stem and storage root, respectively. The highlight of this work is that the genes involved in light response, such as those for photosystem I (PSA) and photosystem II (PSB), other genes involved in light harvesting, and some of the genes in the Calvin cycle of carbon fixation were specially upregulated in leaf. Genes for transport and also for key rate-limiting enzymes (PFK, PGK and PK, GAPDH) coupling ATP consumption in glycolysis pathway were predominantly expressed in stem, and genes for sucrose degradation (INVs), amylose synthesis (GBSS) and hydrolysis (RCP1, AMYs), the three key steps of starch metabolism, and transport associated with energy translocation (ABC, AVPs and ATPase) and their upstream transcription factors had enhanced expression in storage root in domesticated cassava. Co-expression networks among the pathways in each organs revealed the relationship of the genes involved, and uncovered some of the important hub genes and transcription factors targeting genes for photosynthesis, transportation and starch biosynthesis.

The current phosphate recycling situation in China and Germany: a comparative review

Qing XUE, Xinyue HE, Saskia D. SACHS, Gero C. BECKER, Tao ZHANG, Andrea KRUSE

Frontiers of Agricultural Science and Engineering 2019, Volume 6, Issue 4,   Pages 403-418 doi: 10.15302/J-FASE-2019287

Abstract:

Phosphorus (P) is an indispensable element for organisms but the primary source of P—mineral phosphate resources—are non-renewable. Agricultural production has a high demand for fossil phosphate resources, but the resulting phosphate-rich residues are lack of management. This leads to rapid reserves depletion and severe phosphate pollution risks. One sustainable way is to reuse the phosphate dispersed in various residues such as sewage sludge and livestock manure. Diverse techniques have emerged to recover phosphate from wastes to close the phosphate cycle. While it is a global issue, the regional situations regarding potential phosphate scarcity and its management differ strongly. China is rich in phosphate resources, but over-exploitation has greatly increased the risk of phosphate rocks depletion, while in Germany the P resources depend on imports, but there is commitment to keep a balance between import and utilization. This had led to great differences in the way the two countries deal with the “re-use” of phosphate in waste. China is now in a transition phase from the simple terminal pollution control to “waste” reuse and nutrient resources recycling. One sign of this tendency is the mandatory garbage classification and preparation for further processing and recycling. This was first implemented in Shanghai in 2019, whereas Germany has been following the legal framework for waste management since the 19th century. There are a series of laws to control the nutrient loss from municipal and agricultural activities, as for instance with sewage sludge ordinance and fertilizer legislation. Many of these laws have been newly revised recently. Sewage sludge cannot be directly utilized on farmland as organic fertilizer any more. Alternatively, phosphate and other nutrients should be recovered from sewage sludge. Advanced phosphate recovery technologies and related nutrient recycling schemes are proceeding. This review summarizes the current situation of phosphate-containing residues management and phosphate reuse in China and Germany. The state legislation and policies, which would affect the phosphate recycling concept are presented as well. As there are various kinds of phosphate-containing residues, different phosphate recovery technologies can be applied. Those technologies are discussed from their mechanism and suitability.

Yu Zhongguang, Zhang Pengjun, Zhang Zhixin, Wang Chen

Strategic Study of CAE 2020, Volume 22, Issue 1,   Pages 139-145 doi: 10.15302/J-SSCAE-2020.01.018

Abstract:

The medical specialty catalogue is of great significance for promoting the development of the medical discipline and cultivating qualified medical talents; therefore, a comprehensive and scientific medical specialty catalogue becomes even more important in the context of constructing first-class disciplines in colleges and universities. To promote the progressive development of medical disciplines in China, this research sorted out the medical specialty category by literature analysis, and systematically compared the features and category of medical specialty among the U.S. and the U.K. and China. Several major problems are raised as follow: non-uniform medical specialty and sub-specialty category, outdated arrangement of specialties in quantities and content, premature entry into sub-specialty training, inconsistent categories with standardized residential training, etc. To tackle the problems above, this research suggests that the medical specialty category should be in track with global standard, unified with interdisciplinary approach,and standardized admission and exit criteria be set up, which will prepare future qualified health professionals and promote the advancement of medical disciplines.
