Epoxy ternary systems were prepared from the diglycidylether of bisphenol-A (DGEBA), epoxidized castor oil (ECO), and nano-CaCO3 using a thermally latent initiator. The effects of ECO and the nano-CaCO3 contents on the thermal stability and mechanical interfacial properties of the prepared DGEBA/ECO/nano-CaCO3 ternary systems were examined by thermogravimetric analysis (TGA), Izod impact tests,...

The bio-thermodynamic structures of a mixed native species plantation, a conifer plantation and an Acacia mangium plantation in Southern China were quantified over a period of 15 years based on eco-exergy methods. The efficiencies of structural development and maintenance were quantified through an integrated application of eco-exergy and emergy methods. The results showed that the storage of e...

This paper aims to contribute to understanding the dynamics of industrial symbiosis. More specifically, we focus on the dynamics of anchoring as they can be observed in the Chinese context of eco-industrial development. We define anchoring as those activities that (typically local) actors perform to create local physical and institutional conditions conducive to the emergence and further develo...

objective(s): the development of reliable and ecofriendly process for the synthesis of nano-metals is an important aspect in the field of nanotechnology. nano-metals are a special group of materials with broad area of applications. materials and methods: in this study, extracellular synthesis of silver nanoparticles (snps) performed by use of the gram positive soil streptomycetes. streptomycete...

to enhance solubility and the performance of a plant gum (from south peach tree of china, sp gum) as a drilling fluid additive, we explored the potential of modified sp (msp) gum by modifying it with epichlorohydrin. the modification conditions, such as the mass ratio of  the crosslinking agent, ph and temperature, were optimized and the results show that 56.40 g/100g mass ratio of the crosslin...

Open innovation runs contrary to the individualistic mentality of traditional corporate R&D implementation while embracing external cooperation in a complex world. Our main motivation for study is assess and characterize knowledge structure that represents radical transformation toward accelerating co?development sustainable innovations. review points role open eco-innovation research landscape...

At present, overseas and domestic eco-security early warning research is in the exploratory stage. This paper uses Kizilsu Kirghiz Autonomous Prefecture as the research object and constructs an evaluation index system based on the pressure-state-response (P-S-R) conceptual model. This study analyzes eco-security early warning in the study area using the granger causality test model, the entropy...

eco village design is a new field of knowledge still under development. it will be the physical manifestation of the unfolding of the ecovillage dream held by so many. it is generally agreed that concept of sustainability should play an increasing role in future urban development world-wide. in order to ensure ecological sustainability, cities around the world have to decrease their environment...

There is a gap in the geographical/geopolitical literature about the process that motivates humans to conquer a boundless, timeless and invaluable wilderness in the name of plural ecologies to serve their own political interests in control and territory building by means of ‘green gerrymandering’. The ecological frontier (or eco-frontier), a neologism produced by a contemporary greened civil so...
