Simulation study of shock wave reaction on porous materia

Xu Aiguo,Zhang Guangcai,Yu Xijun,Pan Xiaofei,Zhu Jianshi

Strategic Study of CAE 2009, Volume 11, Issue 9,   Pages 13-19

Abstract:

Complex spatial-temporal dissipative structures occur in shocked porous material. The system is globally in nonequilibrium. Both the simulation and data analysis for such a system are challenging.The system was simulated by using the material-point method which was developed recently. The Minkowski functionals were introduced to describe the Turing pattern of the map of state variable like temperature.The relevance among the three Minkowski functionals,the area fraction of the high-temperature regions and the distribution of "hot-spots"  in space was pointed out.The shock wave reaction with inhomogeneous material was studied by analyzing the evolution of Minkowski functionals. The effects of porosity and shock-wave-strength were investigated.

An experimental characterization of human torso motion

Daniele CAFOLLA,I-Ming CHEN,Marco CECCARELLI

Frontiers of Mechanical Engineering 2015, Volume 10, Issue 4,   Pages 311-325 doi: 10.1007/s11465-015-0352-z

Abstract:

The torso plays an important role in the human-like operation of humanoids. In this paper, a method is proposed to analyze the behavior of the human torso by using inertial and magnetic sensing tools. Experiments are conducted to characterize the motion performance of the human torso during daily routine operations. Furthermore, the forces acting on the human body during these operations are evaluated to design and validate the performance of a humanoid robot.

Synthesis and characterization of norfloxacin biomonomer

Shengxiong DONG, Qiaoping CHEN, Hongfang XIE, Jianhua HUANG

Frontiers of Chemical Science and Engineering 2011, Volume 5, Issue 1,   Pages 55-59 doi: 10.1007/s11705-010-0537-2

Abstract: A novel drug agent named norfloxacin biomonomer was developed in order to solve the problem of low drug content, uneven drug distribution, low molecular weight, and wide molecular weight distribution of polymer drug, based on polyurethane, which was used as an antibacterial agent to control the bacterial infection associated with biofilm formation on polymeric materials used in biologic environments. In this research, norfloxacin biomonomer was synthesized by esterifying the compound of norfloxacin. High-performance liquid chromatography system was used to analyze the purity of the final product and intermediate products, and Fourier transform infrared spectrometer and mass spectrum were used to verify the final product and intermediate products. The results showed that the objective product was developed successfully. The final product of norfloxacin biomonomer could be incorporated into the polyurethane as chain extender.

Microplastic and Nanoplastic Pollution: Characterization, Transport, Fate, and Remediation Strategies

Frontiers of Environmental Science & Engineering 2022, Volume 16, Issue 1,   Pages 12-12 doi: 10.1007/s11783-021-1446-y

Abstract: Plastics continues to have a critical and essential role in human society such as food packing, product packages and building materials. In the meantime, it has been recognized as a global sustainability priority to study and mitigate pollution of plastics and the associated unknown impacts from ultrafine plastic particles. Microplastic (<5 mm) particles, for instance, have been detected in the aquatic environment globally and have raised scientific interests and environmental concerns. Microplastics (MPs) can enter rivers through a variety of pathways (e.g., wastewater effluent, breakdown of plastic debris) and can negatively impact aquatic organisms through both direct injection with food and indirect contamination from absorbed toxins. MPs can absorb heavy metals, pathogens, and organic contaminants, mainly persistent organic pollutants (POPs) that can be ingested by organisms and introduced into the food web. Meanwhile, MPs may also release potentially toxic substances (e.g., plasticizers, flame retardants and antimicrobial agents) during weathering and degradation. An increasing number of papers are being published during the last years related to the effects of MPs as well as with synergistic effects when associated with MPs and their byproducts such as nanometer sized plastics or nanoplastics. This special issue successfully garnered a collection of research articles that addressed various topics of microplastic or nanoplastic pollution, characteristic, and environmental fate in the water environment. Particularly, this issue reported the seasonable occurrence and distribution of microplastics in different regions (e.g., China and India) from high-latitude nature reserve to sediments and coastal marine environments. Moreover, new sampling and analytical methodologies (e.g., fluorescent labeling) to identify MPs in diver matrixes (e.g., wastewater, sediment, and biota) are critically reviewed. The information is critical for scientists, business leaders, legislators, and the public are to explore and develop solutions that lessen society’s plastic footprint. We thank all authors, reviewers, and editorial staff of FESE for their efforts and contributions to this special issue.
