New, active and stable catalysts competitive to Pt catalysts are necessary for fuel cell development. Here, we present few-layered graphene-supported Pd, revealing a performance superior to Pt/C and Pd/C ORR (positive half-wave potential shift E(1/2) by 50 mV, approximately one order of magnitude higher area- and mass-normalized current densities, I(area), I(mass), after 2500 cycles). The catal...

Cooperation has been studied extensively across the tree of life, from eusociality in insects to social behavior in humans, but it is only recently that a social dimension has been recognized and extensively explored for microbes. Research into microbial cooperation has accelerated dramatically and microbes have become a favorite system because of their fast evolution, their convenience as lab ...

Standing deadwood is an important structural component of forest ecosystems. Its occurrence and dynamics influence both carbon fluxes the availability habitats for many species. However, greatly reduced in managed, even currently unmanaged temperate forests Europe. To date, few studies have examined how environmental factors, management changing climate affect standing its dynamics. Data from f...

Eco-efficiency has emerged as a management response to waste issues associated with current production processes. Despite the popularity of the term in both business and government circles, limited attention has been paid to measuring and reporting eco-efficiency to government policy makers. Aggregate measures of eco-efficiency are needed, to complement existing measures and to help highlight i...

Eco-innovation always needs inspiration. This paper presents eco-innovative examples for 40 TRIZ inventive principles. These examples cover a wide range of products and processes. They are novelty, creative and eco-friendly.

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...

Using remote sensing (RS) data and geographical information system (GIS), eco-environmental vulnerability and its changes were analyzed for the Yellow River Basin, China. The objective of this study was to improve our understanding of eco-environmental changes so that a strategy of sustainable land use could be established. An environmental numerical model was developed using spatial principal ...

Plasmids of approximately 80 kb in size are found in nearly all clinical isolates of Salmonella dublin and are believed to be essential for virulence. We have shown previously that the 80-kb plasmid pSDL2 is required for the S. dublin Lane strain to establish a lethal systemic infection in BALB/c mice after oral or intraperitoneal inoculation. We now present a physical and genetic characterizat...

Component alpha DNA is a highly repetitive sequence that comprises nearly a quarter of the African green monkey (Cercopithecus aethiops) genome. A previous microbial restriction enzyme analysis showed that the repeat structure of component alpha DNA is based upon a monomeric unit of 176 +/- 4 base-pairs. An endonuclease, provisionally termed Case I, has been isolated from African green monkey t...
