Co‐Electrospinning Extracellular Matrix with Polycaprolactone Enables a Modular Approach to Balance Bioactivity and Mechanics of a Multifunctional Bone Wrap

Advanced Healthcare Materials, EarlyView.
The incorporation of nondigested ECM and synthetic polymers into a co‐electrospinning system enables the decoupling of bioactivity and mechanical properties within a single wrap. This technique is used to develop a multifunctional bone wrap that achieves augmented membrane durability, sustained infection control, and enhanced vascularity for use in ...

Approximating Generalized Network Design under (Dis)economies of Scale with Applications to Energy Efficiency

, 2018
In a generalized network design (GND) problem, a set of resources are assigned to multiple communication requests. Each request contributes its weight to the resources it uses and the total load on a resource is then translated to the cost it incurs via ...

A Functional 2D Carbon Allotrope Combining Nanoporous Graphene and Biphenylene Segments

Advanced Materials, EarlyView.
The synthesis of a novel nanoporous graphene (NPG) is reported with biphenylene segments via thermal fusion of 12‐armchair porous graphene nanoribbons grown on gold surfaces. Characterization using STM, AFM, and DFT reveals low‐defect semiconducting behaviour and tunable band gaps.

Potential habitats and historical distribution changes of three species of musk deer in China under habitat fragmentation

Endangered Species Research
Species potential habitat modeling and quality assessment are useful tools for effective conservation of endangered animals. Species distributions are influenced by environmental variables such as topography, climate, and anthropogenic disturbance.

Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD

Advanced Materials, EarlyView.
Combining STM measurements and ab‐initio calculations, we show that zig‐zag edges in graphene nanoislands grown on Ni(111) by CVD retrieve their spin‐polarized edge states after intercalation of a few monolayers of Au. ABSTRACT Spin‐split states localized on zigzag edges have been predicted for different free‐standing graphene nanostructures.

Sustainability-focused leadership and pro-environmental behavior in SMEs: through the lens of conservation of resources theory [PDF]

Central European Management Journal
PurposeBased on the conservation of resources theory (COR), we examined how sustainability-focused leadership (SFL) influences pro-environmental innovative behaviors (PEIBs) by exploring employee well-being (EWB) as a mediating mechanism. Thus, the study

To what degree are philosophy and the ecological niche concept necessary in the ecological theory and conservation? [PDF]

, 2017
Ecology as a field produces philosophical anxiety, largely because it differs in scientific structure from classical  physics. The hypothetical deductive models of classical physics are simple and predictive; general ecological models are ...
