Prof. C. W. Lim, City University of Hong Kong, Hong Kong

Speech Title: A New Symplectic Approach for Thermal Buckling of Cylindrical Shells

 

Abstract: In the aftermath of 911, thousands of lives were sacrificed mainly due to the collapsed of two tall buildings resulted from excessive temperature that weakened the building structures.  In this aspect, we intend to study the effects of temperature on the possible collapse of building due to structural buckling.  Specifically, the research here deals with thermal buckling of cylindrical shells in a uniform temperature field based on the Hamiltonian principle in a symplectic space.  In the system, the buckling problem is reduced to an eigenvalue problem which corresponds to the critical temperatures and buckling modes.  Unlike the classical approach where a predetermined trial shape function satisfying the geometric boundary conditions is required at the outset, the symplectic eigenvalue approach is completely rational where solutions satisfying both geometric and natural boundary conditions are solved with complete reasoning.  The results reveal distinct axisymmetric buckling and non-axisymmetric buckling modes under thermal loads.  Besides, the influence for different boundary conditions is discussed.

Keynote Speaker III

Prof. Xiaohong Zhu, Sichuan University, China

Speech Title: Graphene-based Electrode Materials for Supercapacitors

 

Abstract: Graphene has attracted much attention since it was firstly stripped from graphite by two physicists in 2004, and the supercapacitor based on graphene has obtained wide attention and much investment as well. However, there are many problems to solve in practical application of graphene-based supercapacitors, for instance, how to reduce the cost and simplify the fabrication process and how to improve further the electrochemical performance. In this talk, I will present our recent breakthroughs in fabricating graphene-based electrode materials for high-performance supercapacitors. First of all, to avoid graphene restacking, we come up with a pumping paper process, that is, when we use force to draw the paper from a small pore, the paper would fold. So here, we report a novel strategy to prepare wrinkled flower-like graphene through a simple suction filtration process. The wrinkled flower-like graphene shows a high specific capacitance of 272 F g-1 and a perfect capacitance retention of 99.5% after 2,000 times of charging/discharging cycles. Second, graphene/MnO2 and graphene/Ni(OH)2 composites with high electrochemical performance are prepared. Last but not least, 3D hierarchical porous carbon-based electrode materials (3DHPCs) with a composite structure are prepared from a biomass waste, sheep manure, by a facile carbonization and activation process without using any additional template. Benefiting from the composite structure, the ions experience a variety of environments, i.e., graphene-like sheets, nanotube- and microtube-like pores coexist in the same material, which, in turn, contribute significantly to the excellent electrochemical properties of supercapacitors, comprising high specific capacitance, outstanding rate capability and excellent long cycle stability. The specific capacitance at large current densities of 1 A g-1 and 50 A g-1 reaches as high as 486 F g-1 and 411 F g-1, respectively, in 6 M KOH electrolyte. Furthermore, the supercapacitor device based on 3DHPCs shows a superior cycle stability with almost 100% retention of the initial specific capacitance after 10,000 cycles; in addition, it yields a Ragone curve with high energy and power density combinations of 57.08 Wh kg-1 at 25.37 kW kg-1.

Prof. Chien-Yuan Chen, National Chiayi University, Taiwan

Speech Title: Application of Thermal Images for Determining the Vegetation Coverage Ratio at Free-Frame Shotcrete Grid Beam Protected Slope

 

Abstract: In this study, infrared thermography was used to determine the vegetation coverage ratio (VCR) at a free-frame shotcrete grid beam-protected slope. An infrared thermal imager can detect the changes in surface radiation temperature on naked and vegetation-covered slope areas. Regional temperature analysis was performed through thermography, and the average temperature derived from the captured thermal images was used as the index for the vegetation area; the VCR was also evaluated. This method can be used in engineering practice after construction to reduce the errors in subjective visual judgment and can also serve as an effective and scientific evaluation methodology. A long-distance noncontact detection method for VCR evaluation can increase the engineering applicability of the proposed method after construction.

Plenary Speaker II

Prof. Andrew Boyd, McGill University, Canada

Speech Title: Using Tensile Strength of Concrete to Evaluate Deterioration

Abstract:  The vast majority of deterioration mechanisms in concrete revolve around the development of some form of internal expansive stress that causes cracking within the hydrated cement paste. Whether this expansive stress is due to the expansion of water during freezing, the expansion of alkali-silicate gel during an alkali silica reaction, or the formation of ettringite during sulfate attack, the mechanical effect is the same. Even the corrosion of reinforcing steel results in a volume increase of the steel that induces stress to the surrounding concrete. Cracking in a brittle material like concrete is a tensile phenomenon, and thus the evaluation of mechanical properties induced by such deterioration should rely on tensile strength evaluation. However, measuring the tensile strength of a brittle material, particularly concrete, is not easy. For example, gripping the specimens without inducing additional stresses and localized failure at the contact points is difficult. This presentation describes the development of an alternative technique that induces an internal pore pressure using a non-contact gas pressure loading approach. It is capable of generating a true tensile failure from the inside, using the diphase concept of load application. Though the fundamental form of this method for static tensile strength determination has been used for quite some time, recent developments to the apparatus have now expanded its capabilities to include long-term sustained loading (creep), cyclic loading, or any combination of loading and unloading the researcher desires. Results from testing various forms of deterioration have shown that the pressure tension test is capable of detecting damage at much lower levels, or at significantly earlier stages, than other destructive testing techniques currently in use.

Plenary Speaker IV

 

Prof. Cattaleeya Pattamaprom, Thammasat University, Thailand

Speech Title: Low-cost Bio-based Toughening agents for Polylactic Acid

Abstract: Poly(lactic acid) (PLA) is one of the most prevalent and the cheapest bio-based and biodegradable polymers used in many packaging applications. The advantages of PLA are its transparency and gloss. On the other hand, the brittleness and poor processability of neat PLA make it not suitable for packaging films and high impact applications. To improve toughness and processability of PLA while maintaining its bio-based, several additives and toughening agents have been investigated and one of the most effective polymers for improving toughness of PLA is Polybutyrate adipate-co-terephthalate (PBAT). However, the high cost of PBAT makes the compounds not cheap anymore. Other polymers could provide excellent toughness to PLA but they are not bio-based. Natural rubber (NR) is an interesting candidate for toughening PLA because NR is a rather inexpensive bio-elastomer which possesses high elasticity, high tensile strength, high tear resistance and high abrasion resistance. However, the incompatibility of NR and PLA leads to phase instability and agglomeration of NR domains. In this talk, several techniques have been applied to improve dispersion and phase stability of NR in PLA matrices and the improvement in the impact strength and properties of final film products will be described.  

Biography: Prof. Cattaleeya Pattamaprom was born on September 7, 1973. Prof. Cattaleeya achieved a B.S. in Chemical Engineering from Chulalongkorn University, Thailand.
