1Effect of Konjac Food on Blood Glucose Level in Patients with Diabetes显示文摘Seventy-two type II diabetic subjects were given Konjac food for 65 days. The data analyzed by multiple F test indicate that the fasting blood glucose (FBG) and the 2-h postprandial blood glucose (PBG) on the 30th and the 65th days after the food was ingested were significantly reduced (P = 0.001, P < 0.001, respectively), as was the glycosylated hemoglobin level at the end of the trial (P < 0.05). The final FBG and PBG of the subjects with initial FBG-O >200 mg% decreased on the average by 51.8 and 84.6 mg%. respectively; those with FBG-0 150-200 mg% decreased by 24.1 and 68.7 mg%; and those with FBG-O < 150 mg% decreased by 4.8 and 21.4 mg%. No significant changes in blood lipid indexes were observed, except that the triglycer-ide values of subjects with hypertriglyceridemia (>200 mg%) significantly decreased by 118.7 mg%. It was concluded that Konjac food is very useful in the prevention and treatment of hyperglycemia. (C)1990 Academic Press.

6Mechanical Behavior of Single and Bundled Defect-Free Carbon Nanotubes显示文摘CONSPECTUS:Superstrong materials can be utilized in many fields such as bulletproof vests,airframes,suspension bridges,flywheel energy storage,etc.As one of the strongest materials,carbon nanotubes(CNTs)can potentially be used to fabricate superstrong fibers.However,the tensile strength of CNTs is impaired a lot by defects,and the CNT fibers prepared so far have strengths much lower than that of a single CNT,showing a“size effect”.The conventional study of solid mechanics is usually based on the assumption that materials contain defects.Defect-free ultralong CNTs can hopefully help us avoid the“size effect”of nanomaterials and produce superstrong CNT fibers.They would also provide a system for the study of the mechanical behavior of ideal solids with a nonlocalized“quantum stress singularity”.In this Account,we discuss our recent studies on the mechanical behavior of defect-free single CNTs and CNT bundles.First,we introduce the defect-free structure of ultralong CNTs,which is one type of ideal solid.Second,we review the investigation of the static tensile properties and dynamic fatigue resistance and their temperature-dependence of single centimeters long defect-free CNTs.The results showed that defect-free CNTs have superior comprehensive mechanical properties,including superstrength,-toughness,and-durability.Different from traditional materials,the fatigue lifetime and fracture of CNTs are dominated by the first single-bond-sized defect(quantum stress singularity),showing“superbrittleness”.Third,by using a gas flow focusing in situ synthesis method as well as a synchronous tightening and relaxing strengthening strategy,we successfully fabricated CNT bundles with tensile strengths approaching that of single CNTs and showed that the“size effect”can be avoided.In addition,the advantages and promising future of using CNTs in flywheel energy storage are discussed.Finally,we provide our perspectives on the challenges and future directions in this field.Yunxiang Bai Hongjie Yue Rufan Zhang Weizhong Qian Zhong Zhang Fei Wei 2021Accounts of Materials Research2021,2,11:1

9Failure-analysis of carbon nanotubes and their extreme applications显示文摘The study of material failure is crucial for the design of engineering applications,as it can have significant social and economic impacts.Carbon nanotubes(CNTs),with their exceptional electrical,mechanical,and thermal properties,hold immense potential for a wide range of cutting-edge applications such as superstrong fiber,lightning strike protector,and even space elevator.This review provides an overview of the advancement in understanding the mechanical and electrical failure study of CNTs and their assemblies,serving as a comprehensive reference for utilizing CNTs in various forms.To begin,we emphasize the importance of studying material failure and provide a brief introduction to CNTs.Subsequently,we explore the mechanical and electrical failure characteristics of CNTs and their assemblies,along with notable examples of applications that utilize their failure-resistant properties,such as flywheel energy storage and lightning strike protection.Lastly,we present perspectives associated with analyzing CNT failure and its implications for extreme applications.Mingquan Zhu Yunxiang Bai Runyi Gao Yajing Liu Peng Zhang Hui Zhang Luqi Liu Zhong Zhang 2023Nano Research2023,16,11:0
10General M-lump,high-order breather,and localized interaction solutions to(2+1)-dimensional generalized Bogoyavlensky-Konopelchenko equation显示文摘The(2+1)-dimensional generalized Bogoyavlensky-Konopelchenko equation is a significant physical model.By using the long wave limit method and confining the conjugation conditions on the interrelated solitons,the general M-lump,high-order breather,and localized interaction hybrid solutions are investigated,respectively.Then we implement the numerical simulations to research their dynamical behaviors,which indicate that different parameters have very different dynamic properties and propagation modes of the waves.The method involved can be validly employed to get high-order waves and study their propagation phenomena of many nonlinear equations.Hongcai MA Yunxiang BAI Aiping DENG 2022Frontiers of Mathematics in China2022,17,5:0
11Controlled growth of crossed ultralong carbon nanotubes by gas flow显示文摘Carbon nanotubes(CNTs)work as the promising components of miniature electromechanical systems due to their ecellent performances from individual to bundle scales.But it's challenging to achieve precise patterning at nanoscale resolution with controlled position and orientation.Here,we demonstrate a fluidic strategy to interlace one-dimensional(1D)ultralong CNTs into the crossed pattern in a one-step in-situ process.Semi-circular substrates of different diameters were placed in front of the growth substrate to change the path and momentum of gas flow.Such flow perturbation caused by substrates could be markedly reflected within a micro-channel reactor,which led to formation of crossed utralong CNTs at definite positions.Furthermore,precise control over the crossing angle as well as the diameter distribution of CNTs was achieved by varying the CNT length and diameter of semi-circular substrates.Our strategy has offered a feasible route for production of crossed ultralong CNTs and will contribute to multidimensional fluidic assembly of flexible nanomaterals.Zhenxing Zhu Yunxiang Bai Nan Wei Jun Gao Silei Sun Chenxi Zhang Fei Wei 2020Nano Research2020,13,7:0
