Advanced Synthesis and Fabrication Strategies for 2D Mesoporous Carbon Materials in Energy Storage and Conversion

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
The rising demand for efficient energy systems has spotlighted 2D mesoporous carbon materials due to their high surface area, tunable porosity, and electrical conductivity. This article explores synthesis methods (template‐assisted, chemical vapor deposition), fabrication techniques (electrospinning, freeze‐drying), and applications in batteries ...

Ökologische und genetische Differenzierung von Daphnia-galeata-Populationen in Europa [PDF]

open access: yes, 2005
Here I analyse 23 populations of D. galeata, a large-lake cladoceran, distributed mainly across the Palaearctic. I detected high levels of clonal diversity and population differentiation using variation at six microsatellite loci across Europe.

On the interplay of speciation and dispersal: An evolutionary food web model in space [PDF]

open access: yes, 2014
We introduce an evolutionary metacommunity of multitrophic food webs on several habitats coupled by migration. In contrast to previous studies that focus either on evolutionary or on spatial aspects, we include both and investigate the interplay between ...

Evolution and Ecology of Actinobacteria and Their Bioenergy Applications.

open access: yesAnnual Review of Microbiology, 2016
The ancient phylum Actinobacteria is composed of phylogenetically and physiologically diverse bacteria that help Earth's ecosystems function. As free-living organisms and symbionts of herbivorous animals, Actinobacteria contribute to the global carbon ...

Functional Starch‐Based Conductive Hydrogel for Flexible Electronics: Design, Construction, and Applications

open access: yesAggregate, EarlyView.
The natural biomass‐based hydrogel is critical to sustainable development of bioelectronic device. Our review introduces design, construction, and applications involved in fabricating starch‐based conductive materials. We also elucidate their synthesis mechanisms, and elaborate on the methods for imparting conductivity to starch and their application ...

Grass functional traits reflect the long history of fire and grazers in the savannas of Texas

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Understanding relationships among grass traits, fire, and herbivores may help improve conservation strategies for savannas that are threatened by novel disturbance regimes. Emerging theory, developed in Africa, emphasizes that functional traits of savanna grasses reflect the distinct ways that fire and grazers consume biomass ...
