The palladium nanoparticle grafted manganese oxyhydroxide nanorod(MON) electrocatalyst has been synthesized and tested for the electrooxidation of ethylene glycol(EG) in an alkaline medium. The MON was prepared using the hydrothermal method and the Pd nanoparticles were coated on the MON using an in situ reduction method. The nanocatalyst thus prepared was characterized by powder X-ray diffraction, scanning electron microscopy, high resolution transmission electron microscopy, energy dispersive X-ray spectroscopy and electrochemical methods. The microscopic studies confirm the formation of MON and reveal that the Pd nanoparticles were grafted uniformly on the MON. In the voltammetric studies, the Pd/MON catalyst exhibited a six-fold improved peak current for ethylene glycol electrooxidation compared with the C/Pd. The EG electrooxidation reaction performances of the Pd/MON nanocatalyst in the alkaline solutions containing different quantities of EG were tested through cyclic voltammetry. The catalytic removal of the poisonous intermediates formed during electrooxidation of EG was explained. The present study shows that MON can act as an active support for the Pd nanocatalyst.

French philosopher Gabriel Tarde is known as a philosopher who describes sociology ontologically with an integrated approach and mostly by means of metaphysical interpretations. Opposing his coeval Durkheim＇s “social fact”, Tarde claims that this notion constitutes a methodological problem and the term “social” of Durkheim＇s crowds out “variability of relations”. According to him, determinants in social relations are more general and dynamic notions, such as： “change”, “contrast”, and “adaptation”. In this respect, not quite celebrated in his era, this philosopher is widely known as a metaphysician as well as a sociologist. His metaphysical ideas are clearly visible in various sections of his works, where he described with inspirations from natural phenomenon. Descriptions and analysis on natural phenomena constitute the greater part of his works. He points out similarities between the universe and the world of men in terms of functioning. Presenting these similarities, Tarde seems to reject any division between the men and the nature built up by “positive philosophy” and modern understanding. With his natural descriptions and concepts he inferred from these descriptions, such as“contradiction” and “harmony”, he almost tries to re-establish the bonds between the nature and the social life. Tarde＇s perception of holistic being and his ideas of “contradiction” and “harmony” in nature, are very close to the most basic axioms of the traditional Chinese thought. As a matter of fact, Tarde denotes these similarities in his novella called “Fragment d＇histoire future （Underground Man）”. It is also an example to display an “East-West encounter” on a fictional plane.

A ternary hybrid membrane architecture consisting of sulfonated fluorinated multi-block copolymer （SFMC）, sulfonated （poly ether ether ketone）（SPEEK） and I or 5 wt% graphene oxide （GO） was fabricated through a facile solution casting approach. The simple, but effective monomer sulfonation was performed for SFMC to create compact and rigid hydrophobic backbone structures, while conventional random sulfonation was carried-out for SPEEK. Hydrophilic-hydrophobic-hydrophilic structure of SFMC enhances the compatibility with SPEEK and GO and allows for an unprecedented approach to alter me- chanical strength and proton conductivity of ternary hybrid membrane, as verified from universal test machine （UTM） curves and alternating current （AC） impedance plots. The impact of GO integration on the morphology and roughness of hybrid membrane was scrutinized using field emission scanning electron microscope （FE-SEM） and atomic force microscope （AFM）. Ternary hybrid showed uniform intercalation of GO nanosheets throughout the entire surface of membrane with an increased surface roughness of 8.91 nm. The constructed ternary hybrid membrane revealed excellent water absorption, ion exchange capacity and gas barrier properties, while retaining reasonable dimensional stability. The well-optimized ternary hybrid membrane containing 5 wt% GO revealed a maximum proton conductivity of 111.9 mS/cm, which is higher by a factor of two-fold with respect to that of bare SFMC membrane. The maximum PEMFC power density of 528.07mW/cm2 was yielded by ternary hybrid membrane at a load current density of 1321.1 mA/cm2 when operating the cell at 70 ℃ under 100% relative humidity （RH）. In comparison, a maximum power density of only 182.06 mW/cm2 was exhibited by the bare SFMC membrane at a load current density of 455.56 mA/cm2 under same operating conditions.

In this study, we developed a general method to analytically tackle a kind of movable boundary problem from the viewpoint of energy variation. Having grouped the adhesion of a micro-beam, droplet and carbon nanotube （CNT） ring on a substrate into one framework, we used the developed line of reasoning to investigate the adhesion behaviors of these systems. Based upon the derived governing equations and transversality conditions, explicit solutions involving the critical parameters and morphologies for the three systems are successfully obtained, and then the parameter analogies and common characteristics of them are thor- oughly investigated. The presented method has been verified via the concept of energy release rate in fracture mechanics. Our analyses provide a new approach for exploring the mechanism of different systems with similarities as well as for understanding the unity of nature. The analysis results may be beneficial for the design of nano-structured materi- als, and hold potential for enhancing their mechanical, chemical, optical and electronic properties.
