Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

open access: yesAdvanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Landscape genetics and gene flow in the banana pathogenic fungus Mycosphaerella fijiensis [PDF]

open access: yes, 2007
Among the different evolutionary forces driving population genetics, gene flow related to dispersal plays a major role in local adaptation processes. However very few studies on plant pathogenic fungi focussed on deciphering gene flow patterns at the ...

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing

open access: yesAdvanced Engineering Materials, EarlyView.
The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

Belize Barrier Reef Transect: How Far Do Coral Reef Fish Larvae Travel In Marine Currents? [PDF]

open access: yes, 2011
The vast majority of coral reef fishes go through a pelagic larval stage, which provides potential for long-distance dispersal by marine currents. Yet planktonic larvae are notoriously difficult to track owing to their small size, and as a consequence ...

Photoswitchable Conductive Metal–Organic Frameworks

open access: yesAdvanced Functional Materials, EarlyView.
A conductive material where the conductivity can be modulated remotely by irradiation with light is presented. It is based on films of conductive metal–organic framework type Cu3(HHTP)2 with embedded photochromic molecules such as azobenzene, diarylethene, spiropyran, and hexaarylbiimidazole in the pores.

Estimation of the stratified dispersal rate [PDF]

open access: yes, 2011
The establishment and spread of invading organisms have dramatic consequences for ecosystems. Many organisms expand their range by being transferred passively over short and long distances simultaneously, thus resulting in a stratified dispersal process.

Intermolecular Interactions as Driving Force of Increasing Multiphoton Absorption in a Perylene Diimide‐Based Coordination Polymer

open access: yesAdvanced Functional Materials, EarlyView.
This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

Which combination of release techniques and ages minimizes post-release dispersal during Oriental Stork reintroduction?

open access: yesJournal of Field Ornithology
Many reintroduction attempts have encountered difficulties with long-distance dispersal of the released animals. In previous studies, release techniques and ages of the released individuals have been tested separately to examine their influence on post ...

Effects of burying and removing dead leaves from the ground on the development of scab epidemics in an apple organic orchard. [PDF]

open access: yes, 2004
Ascospores produced on scabbed leaves in the leaf litter constitute the primary inoculum causing scab infections in apple orchards during the year.
